On the display.

The system control unit 20 records or updates the reference count information counted up by the access counter unit 22 in the database DB 14 in association with the account authenticated by the authentication unit 16 and the authentication date and time, and is referred to in the past from a plurality of terminals. The reference count is classified for each type of industry (financial industry) and displayed on the terminal 10a. Further, after the display of the information search result display area 40 is completed, when the operator clicks on an account group character that displays the pointer in the right button of the reference count, for example, “Finance”, the telephone number information determination device 1 The access log in the transmitted reference count information is displayed in the balloon message 46 on the display of the terminal 10a.

  In the figure, the reference count 42 displays “0” as an example, but it goes without saying that the reference count is displayed when it has been referred to in the past from a plurality of terminals. Further, after the display of the information search result display area 40 is completed, when the operator clicks on an account group character that displays a pointer in the right button of the reference count, for example, “Finance”, the terminal 10a displays the telephone number being searched. It is also possible to send an access log request for a financial account to the telephone number information determination device 1 via the Internet network 12.

  In this case, the telephone number information determination device 1 searches the access log stored in the database DN14 in response to the access log request from the terminal 10a, and sends the financial account access log to the terminal 10a via the Internet 12. Send back.

  The terminal 10 a causes the balloon message 46 to appear so as to be superimposed on the information search result display area 40 on the display, and displays the access log of the financial account in the balloon message 46. The contents to be displayed can include the company-specific account symbol and the access date and time.

  However, the present invention is not limited to a mode in which the search result of the access log stored in the database DB 14 is displayed. For example, the access counter unit 22 of the telephone number information determination device 1 counts up the record currently accessed by the terminal 10a. A later access log can be displayed, or the access log information recorded in the database DB 14 can be transmitted along with the data of the information search result screen transmitted from the telephone number information determination device 1.

  In the present embodiment, the telephone number information determination device 1 can determine the region determination match, the history determination normality, and the real determination actuality and the survey date from the search information transmitted by the terminal 10a.

  Then, the operator can operate the terminal 10a to scroll the screen and display the phone number use history information 48 shown in FIG. 4 on the display. In this telephone number use history information 48, the telephone number status of October 15, 2008 is recorded as “real” as the most recent investigation history, and the latest data from September 04, 2008 to November 25, 2006 is recorded. In the past, the telephone number status can be recorded as “real”, and the operator can display the telephone number usage history information 48 that is the basis for the “normal” history determination by simply scrolling the display. The telephone number usage history information 48 displays telephone number statuses for 23 generations.

  This embodiment takes into account that the credit card industry is dealing with the expected increase in consumer defaults by methods such as closing millions of accounts, reducing credit facilities, and raising interest rates. For example, the credit card industry reviews 100,000 new credit applications and card loan limits every month, but it is effective for computer processing to estimate that many consumers are subscribers of the telephone numbers shown in FIG. Contribute to utilization.

  Specifically, when a predetermined risk factor is detected in the phone number use history information 48, the computer ends the phone number use history analysis, and the phone number for which the assumed risk factor is not detected is “normal”. ”Can be estimated. It is a simple and accurate process to read the phone number usage history information from the beginning to the end using a computer, judge the phone number status, check "real" with a solid, and judge the history judgment to "normal" However, the present embodiment provides a determination process that can effectively use computer resources compared to such an execution process in order to process a credit investigation amount required by the credit industry.

  For example, the risk is estimated based on an empirical rule that there are only about 10,000 phone numbers to detect the risk of about 100 million phone numbers. The load on the computer can be reduced by the determination process of estimating the telephone number that is not to be “normal” or “long-term subscriber number”.

  FIG. 5 is a flowchart showing an operation sequence of the telephone number information determination apparatus 1 according to the embodiment of the present invention. The system control unit 20 executes a telephone number use history analysis start step S50 (hereinafter, step S is abbreviated as “S”) after the authentication unit 16 permits the authentication.

  The system control unit 20 searches the database DB 14 using the telephone number received by the search information receiving unit 18 and executes telephone number field extraction S51.

  In the determination S52 for the degree of risk “5”, even if the use history information of the telephone number being searched is not present or exists in the database DB14, if the telephone number status is a line error history including the most recent (Yes) ( YES), the process branches to S58 and "5" is recorded in the danger element flag CF. The telephone number of the risk factor flag CF “5” is used, for example, as “not classified”, “line error”, “preparing for investigation”, “discontinued” from the latest investigation record to the past investigation record. This corresponds to a non-accumulated history of telephone number history information, which is a telephone number for which a person has no track record of paying out a telephone number. In the determination of the unaccumulated history, the determination process can be completed only by analyzing and determining the telephone number status for one generation.

  Next, the system control unit 20 performs a missing number change analysis S53 of the telephone number field that passes the determination S52 by a non- (NO) determination. This missing number change analysis S53 analyzes whether there is a plurality of histories that transition from the subscription state to the missing number state in the telephone number history information. In this analysis, the missing number change analysis may be terminated at the time when two transition states are detected, and the next step may be performed.

  The system control unit 20 executes the risk “1” determination S54. For example, if the telephone number history information includes a telephone number status that has changed from “real” to “missed” twice (YES) ), The process branches to S59, and “1” is recorded in the danger element flag CF.

  Here, the “transition of the telephone number status” is, for example, 1 when the telephone number history information is read back from the most recent survey date to the past survey date, the telephone number status is read, and “real” is read after “missing number”. The transition is detected and the process is continued to determine whether or not there is a second transition. Then, when the transition state is detected twice, the telephone number status transition detection process may be terminated and the process may proceed to the next step.

  However, the present invention is not limited to a mode in which the telephone number status is read back to the past survey date. For example, the telephone number status is read back from the earliest survey date to the most recent survey date. Even if “missing number” is read, one transition can be detected.

  The system control unit 20 performs an effective change analysis S55 of the telephone number field that passes the determination S54 by a non- (NO) determination. This effective change analysis S55 analyzes whether there are a plurality of histories that transition from the missing number state to the joined state in the telephone number history information. For example, it is analyzed whether there are a plurality of histories transitioning from “missing number” to “real”. In this analysis, the missing number change analysis may be terminated at the time when two transition states are detected, and the next step may be performed.

  The system control unit 20 executes a risk “1” determination S56. For example, if the telephone number history information includes a telephone number status that has changed from “missing number” to “real” twice (YES (YES). ) And branch to S60 to record “1” in the danger element flag CF.

  When the risk control flag CF process of S58, S59, and S60 described above is executed, the system control unit 20 shifts the process to search result output and count-up S61, and combines the information search result screen with the terminal 10a or the terminal 10b. Is displayed on the display and the process is terminated.

  On the other hand, when the system control unit 20 makes a non-NO determination in the risk “1” determination S56, the process proceeds to a risk 2 to 4 determination S57. In the risk level 2 to 4 determination S57, the latest (latest) state analysis S62 is executed. In this state analysis S62, for example, the latest (latest) telephone number status in the telephone number history information is read and the process proceeds to the risk “2” determination S63.

  The system control unit 20 executes risk level “2” determination S63, determines whether or not the telephone number status recorded on the most recent investigation date of the telephone number history information is “missing number”, and “missing number”. If YES, it is determined YES (Yes), the process branches to S69, and "2" is recorded in the risk element flag CF.

  On the other hand, the system control unit 20 branches the process to the immediately preceding analysis S64 when making a non- (NO) determination in the risk “2” determination S63. This latest analysis S64 reads and analyzes the telephone number status surveyed before the latest survey date. That is, a phone number having a history other than “missing number” is analyzed for the phone number status of the most recent survey date.

  The system control unit 20 executes a risk “3” determination S65, and determines whether or not the telephone number status recorded on the survey date immediately before the most recent survey date of the telephone number history information is “missing number”. If it is “missing number”, it is determined to be YES (YES), the process branches to S70, and “3” is recorded in the risk element flag CF.

  On the other hand, the system control unit 20 branches the process to the call stop analysis S66 when determining non- (NO) in the risk “3” determination S65. This call stop analysis S66 reads and analyzes the telephone number status to determine whether a plurality of “call stop” is recorded in the telephone number history information. For example, in this analysis, when the “call stop” is detected twice, the call stop analysis may be terminated and the process may proceed to the next step.

  The system control unit 20 executes the risk “4” determination S67 to determine whether or not the “call stop” of the telephone number status is detected twice in the telephone number history information. It is determined YES (YES), the process branches to S71, and “4” is recorded in the danger element flag CF.

  Further, when the system control unit 20 makes a non-NO determination in the risk “4” determination S67, the system control unit 20 branches the process to a risk non-detection S68. This risk level non-detection S68 is based on the condition that any risk history is not determined in the determination of the history of the above-described unaccumulated, missing number transition, actual transition, latest missing number, last missing number, for example, For example, a history determination that determines a telephone number of a search information as a long-term subscriber number including a contracted telephone number in which the status of “real”, “departure”, or “temporarily removed” that does not correspond to a risk factor is continuous. Information is generated, and “0”, “space” or “normal code” is recorded in the danger element flag CF.

  The system control unit 20 executes the risk element flag CF process of any one of S68, S69, S70, and S71 described above, and then shifts the process to a search result output and count-up S72 to be combined with the terminal 10a or the terminal 10b. The information search result screen is transmitted and displayed on the display, and the process is terminated.

  In the search result output and count-up S61, the system control unit 20 may return the numerical value recorded in the flag CF to the terminal 10a or the terminal 10b as a determination result as it is, and converts the numerical value recorded in the flag CF into a character string. The determination result may be returned to the terminal 10a or the terminal 10b. For example, CF “1” is replied so as to notify and display the degree of danger with a character string “there are many repetitions of actual and missing numbers” and CF “5” is “undecidable”.

  Further, in the search result output and count-up S72, the system control unit 20 may return the numerical value recorded in the flag CF as it is as the determination result to the terminal 10a or the terminal 10b, and the numerical value recorded in the flag CF is converted into a character string. You may convert and return to the terminal 10a or the terminal 10b as a determination result. For example, CF “2” is a character string “Most recent is missing”, CF “3” is “Slight history”, CF “4” is “There are many calls stopped”, and CF “Normal value” is “Normal”. Reply so that the danger level is informed.

  Further, the system control unit 20 may detect an event that transitions from any one of the “real”, “call stop”, and “removed” phone number statuses to “missed number” in the risk “1” determination S54. Good. In short, if the event of transition from a telephone number in a subscription contract to a telephone number that has not been subscribed or has been canceled is detected, the reliability of the telephone number can be determined.

  Similarly, the system control unit 20 detects an event that transitions from the telephone number status of “missing number” to any one of “real”, “call stop”, and “removed” in the risk level “1” determination S56. May be. In short, the reliability of a telephone number can be determined by detecting an event in which the telephone number that has not been subscribed or the contract has been changed to a telephone number that has been subscribed.

  Similarly, the system control unit 20 corresponds to any one of “transfer”, “preparing for investigation”, “abolition”, and “no station number” equivalent to “missing number” in the risk “3” determination S65. It may be detected whether or not. In short, it is possible to determine the credibility of a telephone number that has not been subscribed or has been canceled.

  In this embodiment, in order to increase the accuracy of the phone number history determination, the phone number area information is searched from the database DB 14 using the zip code information provided as the search information by the terminal 10a or the terminal 10b, and the area information is output and searched. It is also possible to determine whether or not it matches the station number area of the telephone number being operated and output the area determination information. For example, the area specified in the postal code information is compared with the area number area in charge of the telephone number being searched. If they match, the area determination result is output as `` match '', and if they do not match, the area determination result is By outputting “mismatch”, the operator can easily determine consistency with the telephone number history determination result.

  In the present embodiment, in order to further improve the accuracy of the telephone number history determination, the reference number information of the telephone number searched by the terminal 10a is read from the database DB 14, and the reference number of the telephone number for each account as shown in FIG. It can be displayed on the display 10a.
