Detailed Description
The technical solutions in the present application will be described clearly and completely with reference to the accompanying drawings in the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application relates to a technology of a seed wallet in a blockchain network, in particular to a hierarchical deterministic seed wallet. The seed wallet is a wallet capable of generating innumerable sub-keys through one seed and generating more grandchild keys infinitely through the sub-keys. In addition, only one seed needs to be stored, other child keys and grandchild keys generated by the seed can be deduced, and the generated child keys and grandchild keys can also be applied to different service scenes.
Please refer to fig. 1, which is a schematic diagram of a system architecture provided in the present application. As shown in fig. 1, the system architecture diagram includes a server 100 and a plurality of terminal devices, and the plurality of terminal devices specifically include a terminal device 200a, a terminal device 200b, and a terminal device 200 c. The terminal device 200a, the terminal device 200b, and the terminal device 200c can communicate with the server 100 through a network, and the terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device (e.g., a smart watch, a smart band, etc.). The present application will be described with reference to communication between the terminal device 200a, the terminal device 200b, and the server 100 as an example.
Please refer to fig. 2, which is a scene diagram of a communication method provided in the present application. As shown in fig. 2, the server 100 may be a background server of a carrier that maintains a call service (a call service for a call number). When the server 100 receives a virtual communication number generation request sent by the user B through the terminal device 200a, the server 100 may obtain a seed key 100a of the communication number 105a of the user B according to the virtual communication number generation request, where the seed key 100a includes the master public key 101a and the master private key 102 a. The server 100 may generate a sub-private key 103a from the master private key 102a in the seed key 100a, and then the server 100 may generate a corresponding sub-public key 104a from the sub-private key 103 a. The server 100 may generate a virtual communication address 106a via the child public key 104 a. The virtual communication address 106a is substantially the same as the real communication address corresponding to the communication number 105a of the user B, specifically, the address character string of the virtual communication address 106a is different from the address character string of the real communication address corresponding to the communication number 105a, but the virtual communication address 106a and the real communication address corresponding to the communication number 105a are mapped to the same communication address, and it can be understood that the virtual communication address 106a is mapped to the real communication address corresponding to the communication number 105 a. One virtual communication number 107a corresponding to the communication number 105a of the user B can be obtained from the obtained virtual communication address 106 a. The server 100 may transmit the generated virtual communication number 107a to the terminal apparatus 200a so that the user B can know the virtual communication number 107a corresponding to the own communication number 105a through the terminal apparatus 200 a.
Here, a description is given of the usage of the virtual communication number 107a, as shown in fig. 2, a user B may notify the user a of the virtual communication number 107a corresponding to its own communication number 105a, a terminal device 200B of the user a may respond to a dialing request of the user a for the virtual communication number 107a and dial the virtual communication number, and after the dialing succeeds, the terminal device 200a of the user B may have an incoming call reminder for the communication number 105a (the incoming call reminder may be an incoming call ringing reminder, an incoming call shaking reminder, or an incoming call muting reminder, and a specific reminding manner of the incoming call reminder is determined according to an actual application scenario), that is, the terminal device 200a of the user B has an incoming call, where the incoming call reminder is to prompt that the user B initiates an incoming call to the user a through the virtual communication number 107 a. The terminal 200a can connect a call with the user a in response to a call-on operation of the user B for an incoming call of the user a.
It is to be understood that the virtual communication number 107a corresponding to the communication number 105a of the user B may also be generated by the terminal device 200a, and then the terminal device 200a may send the generated virtual communication number 107a to the server 100, and the server 100 may back up the received virtual communication number 107a corresponding to the communication number 105a of the user B, so that subsequently, the user a may dial through the virtual communication number 107a to dial through the real communication number of the user B. The execution entity (including the terminal device 200a and the server 100 corresponding to the user B) for generating the virtual communication number 107a corresponding to the communication number 105a of the user B is determined according to the actual application scenario, and is not limited thereto.
Through the process, when the user B needs to communicate with the user a but does not want to inform the user a of the real communication number, the user B can inform the user a of the virtual communication number corresponding to the real communication number, so that the user a can initiate a communication request (i.e., initiate an incoming call) for the real communication number of the user B through the obtained virtual communication number, and normal communication between the user a and the user B is realized. Therefore, by the method provided by the application, on the premise that the user B can normally communicate with other users through the real communication number of the user B, the real communication number of the user B can be hidden from other users, and privacy of the real communication number of the user B is improved. The communication number can be a mobile phone number, and the virtual communication number can be a virtual mobile phone number, so that the privacy of the real mobile phone number of the user can be improved by the method provided by the application.
In the following processes, the terminal device is used as the execution agent to generate the virtual communication number corresponding to the communication number, but it should be understood that the server may be used as the execution agent to generate the virtual communication number corresponding to the communication number. The specific execution body for generating the virtual communication number corresponding to the communication number is determined according to the actual application scenario, and is not limited thereto.
Referring to fig. 3, it is a schematic flowchart of a data communication method based on a blockchain network provided in the present application, and as shown in fig. 3, the method may include:
step S101, generating a target random number corresponding to the communication number based on a random algorithm;
specifically, here, the communication number may be a telephone number of any user, and the telephone number may be a telephone number of a landline phone or a mobile phone number. The terminal device may generate a target random number corresponding to the communication number through a random algorithm. The following procedures are all descriptions of processing procedures corresponding to one communication number, and when a plurality of communication numbers need to be processed in the same way, the processing procedures corresponding to each communication number are the same and independent. For example, when a certain user has a plurality of communication numbers and the processing procedure described in the present application needs to be performed on each of the plurality of communication numbers, the processing corresponding to each of the communication numbers corresponding to the user may be performed separately.
Step S102, segmenting the target random number into a plurality of character strings according to the segmentation length threshold;
specifically, the terminal device may segment the generated target random number into a plurality of character strings according to a segment length threshold. Actually, the target random number further corresponds to a check bit for checking the target random number, and the target random number and the check bit corresponding to the target random number may be spliced to obtain a spliced character string (the check bit in the spliced character string is behind and the target random number is in front), so that the spliced character string is split by the split length threshold to obtain a plurality of character strings corresponding to the target random number. The target random number is a binary number, the number of bits of the target random number is 128, and the number of bits of the check bits corresponding to the target random number is 4, so that the number of bits of the concatenated string is 132 bits. The segmentation length threshold may be 11, that is, each 11 bits of the spliced character string are segmented once, and after the segmentation is completed, 12 character strings corresponding to the target random number may be obtained, that is, the plurality of character strings are actually exactly 12 character strings.
The number of bits of the target random number may also be 128 to 256, so that the number of mnemonic words in the obtained mnemonic word string is 12 to 24 (all are segmented according to 11 bits).
Step S103, generating mnemonic word strings corresponding to the communication numbers according to the character strings, and generating seed keys corresponding to the communication numbers according to the mnemonic word strings;
specifically, the terminal device may obtain mnemonic words corresponding to the plurality of character strings in the mnemonic word list; determining the mnemonic word strings corresponding to the communication number according to the mnemonic words corresponding to the character strings respectively:
the terminal device may obtain a mnemonic word list including a mapping relationship between each mnemonic word and the corresponding character string. The terminal device may find the mnemonic word corresponding to each character string obtained by the segmentation in the mnemonic word list. The terminal device may splice the mnemonic words respectively corresponding to each character string obtained by the segmentation to obtain the mnemonic word string corresponding to the communication number. The splicing sequence of the mnemonic words corresponding to each character string is the front-back sequence of the position of each character string in the spliced character strings. The mnemonic word list comprises 2048 mnemonic words, so that the number of the mnemonic words in the mnemonic word list is large, and the uniqueness of the obtained mnemonic word string is ensured to a great extent. In other words, since the number of words of the mnemonic words included in the mnemonic word list is large, it can be understood that the obtained mnemonic word string is not easily derived and is not easily overlapped with (i.e., identical to) the mnemonic word strings corresponding to other communication numbers.
Please refer to fig. 4, which is a schematic view of a scene for obtaining a mnemonic word string according to the present application. As shown in fig. 4, the terminal device may concatenate a random number 100b (i.e., corresponding to the target random number) generated by a random algorithm and a check bit 101b corresponding to the random number 100b to obtain a concatenated string 102 b. The random number 100b is a 128-bit binary number, and the check bit is a 4-bit binary number, so the concatenated string 102b is a 132-bit binary number. The terminal device may segment the spliced character string 102b to obtain a plurality of character strings, where the plurality of character strings includes 12 character strings in total, i.e., a character string 101c, a character string 102c, a character string 103c, a character string 104c, a character string 105c, a character string 106c, a character string 107c, a character string 108c, a character string 109c, a character string 110c, a character string 111c, and a character string 112 c. The terminal device may obtain the mnemonic word table 104b, and the terminal device may find, from the mnemonic word table, the mnemonic word corresponding to each of the character strings obtained by the above-mentioned segmentation, including the mnemonic word 1 corresponding to the character string 101c, the mnemonic word 2 corresponding to the character string 102c, the mnemonic word 3 corresponding to the character string 103c, the mnemonic word 4 corresponding to the character string 104c, the mnemonic word 5 corresponding to the character string 105c, the mnemonic word 6 corresponding to the character string 106c, the mnemonic word 7 corresponding to the character string 107c, the mnemonic word 8 corresponding to the character string 108c, the mnemonic word 9 corresponding to the character string 109c, the mnemonic word 10 corresponding to the character string 110c, the mnemonic word 11 corresponding to the character string 111c, and the mnemonic word 12 corresponding to the character string 112 c. The mnemonic word string 105b can be obtained by concatenating the obtained mnemonic word 1, mnemonic word 2, mnemonic word 3, mnemonic word 4, mnemonic word 5, mnemonic word 6, mnemonic word 7, mnemonic word 8, mnemonic word 9, mnemonic word 10, mnemonic word 11, and mnemonic word 12.
The terminal equipment can determine a salt value corresponding to the mnemonic word string according to the constant character string and the password character string; determining the mnemonic word string and the salt value as input parameters corresponding to a pseudo-random algorithm; calculating the input parameters based on a pseudo-random algorithm and a calculation frequency threshold value to obtain a seed key corresponding to the communication number; the number of times the input parameter is operated on is equal to the operation number threshold:
the salt value can increase the difficulty of cracking the generated seed number, the password character string in the salt value can be determined by a user, and the constant character string in the salt value is a character string constant mnemonic word. Please refer to fig. 5, which is a schematic view of a scenario for acquiring a seed key according to the present application. As shown in fig. 5, the obtained mnemonic word string 101d and the salt 102d may be operated by a pseudo-random algorithm, and the calculation may be repeated according to an operation number threshold, for example, 2048 times (i.e., the operation number threshold is 2048), and a seed number 103d may be obtained after the operation. The larger the threshold of the number of operations is, the larger the difficulty of cracking the seed number 103d finally obtained. Furthermore, the terminal device may generate a mother key, which is the seed key 104d, from the seed number 103d and the key stretching function. Additional subkeys may then be generated from the seed key 104 d. The scheme of hierarchical deterministic seed wallets is adopted, so that all generated sub-keys can be deduced by only storing one seed number or mnemonic word string, and the difficulty of recording the generated sub-keys and the generated mother key is reduced.
Step S104, generating a virtual communication number corresponding to the communication number according to the seed key;
specifically, the seed key includes a master private key and a master public key, the terminal device may generate a sub private key corresponding to the master private key in the seed key, and then the terminal device may generate a sub public key corresponding to the sub private key. The seed key can be operated through an HMAC-SHA512 algorithm (a hash algorithm) to obtain a sub-key, where the sub-key includes a sub-public key and a sub-private key. The terminal device may generate a virtual communication address from the sub-public key, the virtual communication address being in fact mapped to the real communication address corresponding to the communication number. Then, a virtual communication number whose communication address is mapped to the virtual communication address can be obtained from the obtained virtual communication address. The terminal equipment can also uplink the generated virtual communication number to the block chain network for storage.
Step S105, acquiring a communication request aiming at the virtual communication number, and executing a communication service corresponding to the communication request to the communication number according to the communication request;
specifically, the terminal device may obtain a communication request of a communication request device (which may be understood as another terminal device different from the terminal device) for the virtual communication number corresponding to the generated communication number. In practice, the communication request device is a communication request initiated to a virtual communication number (because the communication request device does not know the actual communication number of the terminal device), but the terminal device is a communication service that performs the communication request corresponding to the acquired communication request on the communication number. The communication service corresponding to the communication request may be a short message service or a call service.
The terminal equipment can acquire a call request aiming at the virtual communication number, and acquire an acquisition timestamp corresponding to the call request and an effective time period corresponding to the virtual communication number; when detecting that the obtaining timestamp corresponding to the call request is within the effective time period corresponding to the virtual communication number, executing a call service corresponding to the call request on the communication number:
the terminal device can respond to the valid time setting operation of the virtual communication number of the communication number by the user, and the terminal device can set the valid time period of the virtual communication number through the valid time setting operation. The terminal device can respond to the communication request for the virtual communication number by the communication request device only during the valid period, and outside the valid period, the virtual communication number is in a disabled state, and the terminal device cannot respond to the communication request for the virtual communication number by the communication request device. Therefore, the terminal device can acquire a communication request of the communication request device for a virtual communication number of the communication numbers, and acquire an acquisition time stamp corresponding to the communication request, where the acquisition time stamp is a time point when the communication request is acquired. When the terminal device detects that the obtaining timestamp of the communication request is within the valid time period of the virtual communication number, the terminal device may respond to the communication request and respond to a confirmation operation of the user for the communication request, and execute a communication service corresponding to the communication request. For example, if the communication request device sends a communication request for a call (i.e., calls out from the terminal device) to the terminal device, the terminal device may respond to the received communication request for the call sent by the communication request device and perform a communication prompt, where the communication prompt may be incoming call ringing. The terminal device may respond to a confirmation operation of the user for the call service corresponding to the incoming call ring (that is, the communication service is the call service), and connect the call service with the communication request device (that is, the call service of the successful call is connected, and a corresponding call may be performed between the user corresponding to the communication request device and the user corresponding to the terminal device). When the terminal device detects that the obtaining timestamp of the obtained communication request is not in the valid time period corresponding to the virtual communication number, the terminal device will not respond to the communication request, and will not execute the communication service corresponding to the communication request, and the communication request device may pop up a prompt message of communication failure.
The terminal equipment can acquire a communication request of a visiting communication number aiming at the virtual communication number and acquire an authorized communication number list corresponding to the virtual communication number according to the communication request; when detecting that the visiting communication number exists in the authorized communication number list, executing a communication service corresponding to the communication request to the communication number:
the terminal device may add a corresponding authorized communication number to the authorized communication number list in response to an addition operation of adding an authorized communication number to the authorized communication number list by a user. Only authorized communication numbers that exist in the authorized communication number list can successfully initiate a communication request for a virtual communication number to the terminal device, whereas other visiting communication numbers that do not exist in the authorized communication number list cannot successfully initiate a communication request for a virtual communication number to the terminal device. The communication request device corresponds to a visiting communication number. The terminal device may obtain a communication request initiated by the communication request device to the virtual communication number using the visiting communication number, and when obtaining the communication request, the terminal device may obtain an authorized communication number list corresponding to the virtual communication number. When the terminal device detects that the visiting communication number exists in the authorized communication number list, the terminal device may respond to the communication request, perform a communication prompt, and execute a communication service corresponding to the communication request, or the terminal device may respond to the communication request, and execute the communication service corresponding to the communication request after responding to a confirmation operation of the user for the communication request. When the terminal device detects that the visiting communication number does not exist in the authorized communication number list, the terminal device does not respond to the communication request.
The terminal equipment can acquire a communication request aiming at the virtual communication number, identify a communication type corresponding to the communication request and acquire an authorized communication type list corresponding to the virtual communication number; when detecting that the communication type corresponding to the communication request exists in the authorized communication type list, executing a communication service corresponding to the communication request on the communication number:
the terminal device may respond to a communication type setting operation of the user for the virtual communication number, and create an authorized communication type list corresponding to the virtual communication number. And only when the communication type corresponding to the communication request acquired by the terminal equipment is in the authorized communication type list, responding to the communication request and executing the communication service corresponding to the communication request. And if the communication type corresponding to the communication request acquired by the terminal equipment is not in the authorized communication type list, the communication request is not responded. The communication type of the communication request may include a short message type and a call type. That is, the authorized communication type list may be used to implement a short message service that only opens the virtual communication number, a call service that does not open the virtual communication number (that is, the authorized communication type list only includes the short message type and does not include the call type), or a short message service that only opens the virtual communication number and does not open the virtual communication number (that is, the authorized communication type list only includes the call type and does not include the short message type). The terminal device may obtain a communication request for a virtual communication number sent by the communication request device, may identify a communication type of the communication request, and obtains an authorized communication type list corresponding to the virtual communication number. When the terminal device detects that the communication type of the received communication request is in the authorized communication type list, the terminal device may respond to the communication request and execute a communication service corresponding to the communication. When the terminal device detects that the communication type of the received communication request is not in the authorized communication type list, the terminal device will not respond to the communication request, and will not execute the communication service corresponding to the communication request.
Further, the terminal device may also respond to a user's usage number setting operation for the virtual communication number, by which a usage number threshold value of the virtual communication number may be set. When the number of times that the virtual communication number has been used (i.e., the number of times that the terminal device has successfully responded to a communication request for the virtual communication number) is equal to the above-described usage number threshold, then the terminal device will no longer respond to a communication request for the virtual communication number. When the number of times of use of the virtual communication number is smaller than the above-described number-of-use threshold, the terminal device may respond to a communication request for the virtual communication number and execute a communication service corresponding to the communication request. When the terminal device obtains a communication request of the communication request device for the virtual communication number, the terminal device may obtain a usage number threshold and a usage number (a previously accumulated usage number, which does not include the current usage number) corresponding to the virtual communication number, and when the terminal detects that the usage number is smaller than the usage number threshold, the terminal device may respond to the communication request of the communication request device for the virtual communication number, and execute a communication service corresponding to the communication request. When the terminal device detects that the number of used times is equal to the number-of-used-times threshold, the terminal device does not respond to the communication request for the virtual communication number by the communication request device. And the used times of the virtual communication number are not greater than the used times threshold value of the virtual communication number.
Furthermore, a communication rule of the virtual communication number corresponding to the communication number may also be set, where the communication rule may include a unidirectional communication rule, and the unidirectional communication rule may further include a forward unidirectional communication rule and an anti-unidirectional communication rule. The forward one-way communication rule indicates that the terminal equipment can only respond to communication requests of other visiting communication numbers to the virtual communication number, and the virtual communication number cannot initiate the communication requests of other visiting communication numbers. For example, the terminal device can respond only to a call request (i.e., incoming call) from the other visiting communication number to the virtual communication number, and the terminal device cannot respond to a call request (i.e., outgoing call) from the virtual communication number to the other visiting communication number. For another example, the terminal device can only receive the short message sent by other visiting communication numbers to the virtual communication number, and the terminal device cannot send the short message to other visiting communication numbers through the virtual communication number. The anti-one-way communication rule means that the terminal equipment cannot respond to communication requests of other visiting communication numbers to the virtual communication numbers, and the terminal equipment can initiate the communication requests of the other visiting communication numbers through the virtual communication numbers. For example, the terminal device cannot respond to a call request (i.e., incoming call) by the other visiting communication number to the virtual communication number, and the terminal device may respond to a call request (i.e., outgoing call) by the virtual communication number to the other visiting communication number. For another example, the terminal device cannot receive the short message sent by the other visiting communication number to the virtual communication number, and the terminal device can send the short message to the other visiting communication number through the virtual communication number.
The method includes the steps that firstly, a seed key corresponding to a communication number is obtained; the seed key comprises a main private key corresponding to the communication number; generating a sub private key corresponding to the communication number according to the main private key, and generating a sub public key corresponding to the communication number according to the sub private key; generating a virtual communication number corresponding to the communication number based on the sub public key; the virtual communication number and the communication number have the same communication address; and acquiring a communication request aiming at the virtual communication number, and executing a communication service corresponding to the communication request to the communication number according to the communication request. Therefore, when the communication number is used for communication, the method can externally disclose the virtual communication number corresponding to the communication number without disclosing a real communication number, and improves the privacy of the communication number.
