By the way, from the perspective of ensuring the appropriateness of the test, all test result data should be stored in the storage area, but when a huge amount of tests are performed on test objects, it is difficult to store all the test result data. If this happens, there are concerns that the cost and burden of managing test result data will increase.

The present invention has been made in view of the above circumstances, and aims to provide an inspection system and an inspection method that can ensure the appropriateness of the inspection without increasing the management cost or management burden of inspection result data. This is an issue to be addressed.

To achieve the above object, an inspection system according to the present invention is an inspection system that inspects an object to be inspected, and includes an inspection information acquisition means for acquiring inspection information from the object to be inspected, and an inspection information acquisition means acquired by the inspection information acquisition means. Test information processing means that generates partial information by reducing the amount of information, and test result data generated for each partial information generated by the test information processing means based on the test result data immediately before the test result data was generated. and a database that is stored in a state where it is associated with the immediately preceding test result data using a hash value generated by the method.

According to this, the test result data of the object to be inspected is stored in association with the previous test result data using a hash value generated based on the test result data immediately before the test result data. It becomes virtually impossible to modify only arbitrary test result data.

Moreover, since the test result data is generated based on partial information generated by reducing the amount of test information, unnecessary consumption of the capacity of the database in which the test result data is stored is suppressed.

Therefore, the appropriateness of the test can be ensured without increasing the cost and burden of managing test result data.

In this inspection system, the leader node is a user server managed by a user who is a business operator that inspects the object to be inspected, and the approval node is a business server managed by a business other than the user. The present invention is characterized in that when the result data is transmitted to the approval node and the transmitted test result data is confirmed by the approval node, the test result data is stored in a database different from the database by the approval node.

According to this, when the test result data transmitted to the approval node is confirmed by the leader node, the test result data is stored in a database different from the database by the approval node.

Therefore, since the same test result data as the leader node is stored and managed at the approval node, the appropriateness of the test can be easily confirmed by comparing the test result data of the leader node and the test result data of the approval node. can do.

This inspection system is characterized in that it includes a plurality of approval nodes each managed by a plurality of different businesses, and that the test result data to be stored is set for each of the plurality of approval nodes.

Furthermore, the test information processing means of this test system may generate partial information by extracting a part of the test information, or may generate partial information by compressing the test information. Good too.

By the way, the inspection information used in this inspection system may be binary information of an image of the inspection object.

The inspection method according to the present invention for achieving the above object is an inspection method using an inspection system that inspects an inspection object, and in which the amount of inspection information acquired from the inspection object by an inspection information acquisition means is processed through inspection information processing. partial information is generated by subtracting the partial information, and the test result data generated for each partial information is associated with the previous test result data using a hash value generated based on the test result data immediately before the test result data was generated. The feature is that it is stored in the database in the state in which it is written.

According to the present invention, the appropriateness of the test can be ensured without increasing the management cost or burden of test result data.

In this embodiment, blockchain BC is a consortium-type blockchain that uses PBFT (Practical Byzantine Fault Tolerance), an algorithm that allows consensus building among the user server 30, service provider server 40, and certification provider server 50. It is blockchain.

This blockchain BC includes a block B that stores test result data D1 in the order in which the test result data D1 was generated, and the block B stores the test result data D1 generated immediately before. The generated hash value D2 is stored.

Block chain BC is formed by linking block B in which hash value D2 is stored to the immediately preceding block B that caused this hash value D2 to be generated.

FIG. 6 is a block diagram illustrating the outline of the configuration of the test result data D1. As illustrated, the test result data D1 is composed of test meta information d1 and partial information d2a.

This information processing program 32 is stored in the user server 30 in this embodiment, and includes an input module 32a, a test information processing module 32b serving as test information processing means, a test result data generation module 32c, and a blockchain generation module 32d. .

The input module 32a is a module into which the inspection meta information d1 generated by the inspection device 20 and inspection information as an image acquired by the imaging device 24a installed in the inspection section 24 of the inspection device 20 are input.

The test information processing module 32b is a module that processes the test information input to the input module 32a, and in this embodiment executes a first process and a second process.

In the first process, inspection information as an image of the packaging box 110 captured by the imaging device 24a of the inspection section 24 of the inspection device 20 is binarized and converted into binary information.

FIG. 8 is a diagram illustrating an outline of the second processing by the examination information processing module 32b. As shown in the figure, in the second process, an arbitrary part is extracted from the examination information d2 converted into binary information in the first process, and the extracted part is generated as partial information d2a.

This is a module that checks whether it matches or not.

When the block confirmation module 42a, 52a confirms that the hash value D2 of the block B transmitted from the user server 30 matches the immediately preceding block B, the block storage modules 42b, 52b store the block B as the immediately preceding block. This module is linked to B and stored in the databases 41 and 51.

FIG. 10 is a diagram illustrating an outline of a blockchain network that generates blockchain BC. In the blockchain network of this embodiment, the user server 30 functions as a leader node, and the service provider server 40 and authentication provider server 50 function as approval nodes.

The leader node transmits the block B in which the test result data D1 is stored to the approval node, and when the approval node confirms that the block B matches the immediately previous block B, the approval node transmits the sent block B to the immediately previous block B. Chain to B.

As a result, as shown in the figure, a blockchain BC is generated in which a plurality of mutually adjacent blocks B are chained to the immediately preceding block B in the leader node and each approval node.

In this embodiment, each approval node can set an arbitrary block B to be stored in the generated blockchain BC. This avoids unnecessary consumption of storage capacity in each approval node.

For example, as shown in FIG. 11, blocks B with block numbers 2 and 5 are stored in both approval nodes, block B with block numbers 4 is stored in only one approval node, and blocks with block numbers 1 and 3 are stored in both approval nodes. It is possible to arbitrarily set the block B to be stored in each approval node, such as storing block B only in the other approval node.

Next, operation of the inspection system 10 according to this embodiment will be explained.

First, when the user 1 inspects the packaging box 110 with the inspection device 20, the inspection section 24 acquires inspection meta information d1, and the imaging device 24a of the inspection section 24 generates an image for each inspected packaging box 110. The test information d2 is acquired.

When the examination information d2 is acquired, the acquired examination information d2 is converted into binary information, and then an arbitrary part is extracted from the examination information d2 converted into binary information to reduce the information amount of the examination information d2. Partial information d2a with the subtracted information is generated.

Test result data D1 is generated in the user server 30 using these test meta information d1 and partial information d2a, and the generated test result data D1 is stored in block B. This block B stores a hash value D2 generated based on the block B generated immediately before.

Thereafter, block B is transmitted from the user server 30 as a leader node to the service provider server 40 and authentication provider server 50 as approval nodes.

When block B is transmitted, the approval node checks whether the transmitted block B and the immediately preceding block B match. When a match is confirmed, the approval node chains the transmitted block B to the immediately preceding block B.

As a result, a block chain BC is generated in which test result data D1 generated based on the partial information d2a generated by subtracting the information amount of the test information d2 is stored.

Therefore, it is possible to ensure the appropriateness of the inspection of the packaging box 110 without increasing the management cost or burden on the user server 30, service provider server 40, and certified provider server 50 in which the inspection result data D1 is stored. can.

In particular, in this embodiment, when the leader node transmits the block B in which the test result data D1 is stored to the approval node, a check is performed to see if the block B matches the immediately preceding block B. , if there is a match, the transmitted block B is stored in the databases 41, 51.

Therefore, since the same blockchain BC managed by the leader node, in which the inspection was performed and the inspection result data was stored, is also managed by the approval node, the blockchain managed by the leader node By comparing the BC with the blockchain BC managed by the approval node, the appropriateness of the inspection can be easily confirmed.

Note that the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit of the invention.

In the above embodiment, a case has been described in which an arbitrary part is extracted from the examination information d2 to generate the partial information d2a, but the information amount of the examination information d2 is reduced by compressing the examination information d2. Partial information d2a may be generated.

In the above embodiment, the case where the examination information d2 is an image (binary information) has been described, but it is not limited to an image, and can be various types of information depending on the characteristics of the object to be examined, such as biological information or text information. There may be.

In the above embodiment, a case has been described in which the user server 30 and the service provider server 40 are connected via the network, but the inspection device 20 and the service provider server 40 are connected via the network. may be configured.

In this case, the information processing program stored in the user server 30 is stored in the storage area of the inspection device 20, and the inspection device 20 functions as a leader node.

Furthermore, the inspection unit 24 of the inspection device 20 is equipped with an artificial intelligence program that autonomously determines whether or not there is a defect in the inspection object such as the packaging box 110 based on the image captured by the imaging device 24a. It may be something that
