  An embodiment of the present invention will be described with reference to FIG. The IP access log analysis device 14 of the present embodiment schematically includes an IP address determination unit 18 and a determination data transmission unit 20 provided in a computer 24, and is connected to a storage device 16 that stores address information corresponding to the IP address. The CPU 22 provided in the computer 24 controls the storage device 16, the IP address determination unit 18 and the determination data transmission unit 20. The IP access log analysis device 14 and the user terminal 10 analyze the IP access log included in the request information received from the user terminal 10 by transmitting information to each other via the Internet network 12, and use the analysis result as a user. A reply can be made to the terminal 10.

  The IP access log analysis device 14 of this embodiment shown in FIG. 1 is connected to a storage device 16 (for example, a hard disk) that stores an IP address database DB that stores address information corresponding to an IP address. The illustrated memory, I / O, and storage unit for storing the computer software program are provided, and the CPU 22 executes the computer software program to cause the IP address determination unit and the determination data transmission unit to function.

  The storage device 16 includes, as address (position) information corresponding to the IP address, information specifying the country, region, prefecture, municipality, area code, latitude and longitude, and connection environment information corresponding to the IP address as a domain, Information specifying the line type and proxy usage is stored as an IP address database DB.

  For example, the address information corresponding to the IP address “202.234.1.10” of the Internet service provider (hereinafter abbreviated as “ISP”) can specify Hokkaido, and the connection environment information can specify the ISDN line. Similarly, the address information corresponding to the IP address “202.234.2.100” of the ISP can specify Tokyo, and the connection environment information can specify the FTTH line, and corresponds to the IP address “202.234.3.200”. The address information to be specified can specify Osaka, and the connection environment information can specify the ADSL line.

  However, the present invention is not limited to the IP address database DB stored in the storage device 16. For example, the IP access log analysis device 14 is connected to the IP address database DB of a web server (not shown) via the Internet 12. Address information and connection environment information can also be received and used in real time.

  The operation of the IP access log analyzer 14 will be described with reference to FIGS. 1 and 2.

  The IP access log analyzer 14 receives request information from the user terminal 10 via the Internet network 12 and inputs the request information to the memory area of the IP access log analyzer 14. This request information is exemplified in the XML specification. In step S1, XML version, authentication information “ID = xxx, PASS = xxx”, inquiry IP address “163.135.172.4”, prefecture information “Kanagawa”, municipal information “Kawasaki city” ”, The connection environment information“ FTTH ”, the prefecture code“ 90 ”, the municipality code“ 95 ”, the request information describing the connection environment code“ 85 ”is received by the IP access log analyzer 14 via the Internet 12 and stored in the memory area. input. Next, the CPU 22 executes the IP log information input process on condition that the authentication information matches the account information stored in the storage device 16. The illustrated request information indicates a part of the inquiry IP address and receives a plurality of subsequent inquiry IP addresses from the user terminal.

  The IP access log analysis device 14 can receive request information of the CSV specification in addition to the XML specification from the user terminal 10 via the Internet network 12 and input it to the memory area. In this case, the authentication process is completed between the IP access log analyzer 14 and the user terminal 10 via the Internet network 12. The IP access log analyzer 14 receives condition designation information, IP access log collection date information, branch name information (optional), registration number information, inquiry IP address information, customer registration prefecture name information, customer registration from the user terminal 10 City name information is received via the Internet 12.

  In step S2, the IP access log analyzer 14 causes the IP address determination unit 18 to function and picks up the inquiry IP address “163.135.172.4” in the request information and uses it as a search key. Address information corresponding to the IP address that matches the search key is read from the storage device 16.

  Even if the IP address that completely matches the inquiry IP address “163.135.172.4” does not hit (match) in the storage device 16, the IP address determination unit 18 does not start the first address “163”, the second address When “135” matches the third address “172”, information on the prefecture and the municipality can be acquired as the address information.

  The Ip address determination means 18 shifts the processing to step S3, and determines whether or not the inquiry analysis has been completed for all the inquiry IP addresses of the request information received from the user terminal 10 in the IP address database in the storage device 16. .

  The condition for completing the IP log analysis may be that the reading of the “End Of File” in the request information is detected and it is determined that the IP log analysis of all the inquiry IP addresses is completed. When the maximum value is reached, it may be determined that the IP log analysis is complete. The IP address determination means 18 branches to step S2 (determination result = N) until the determination result “Y” of completion of the IP log analysis in step S3 is output (determination result = N), and repeats the address information extraction processing until the CPU 22 times out.

  In the condition designation information described above, the verification rule ID can be selected from the types “R00” to “R07”. For example, the verification rule ID “R00” executes access verification from an IP address address different from the user registration address.

  The verification rule ID “R01” executes access verification in which the same registration number (credit card number or bank account number) is used from a plurality of IP addresses on the same day.

  The verification rule ID “R02” executes access verification from a plurality of prefectures (identified from the reference IP address) using the same registration number (credit card number or bank account number).

  The verification rule ID “R03” executes access verification in which a plurality of registration numbers (credit card numbers or bank account numbers) are used from the same inquiry IP address (a domain name may be used).

  The verification rule ID “R04” executes access verification with purchase payment using the same registration number (credit card number or bank account number) from a plurality of locations (found from the reference IP address).

  The verification rule ID “R05” executes access verification from a site (domain name or IP address) registered in the black IP list managed by the company that manages the user terminal 10.

  As the verification rule ID “R06”, any one of access verifications from other than Japan can be selected. However, the present invention is not limited to the seven types of verification rules, and other customized verification rule IDs using a reference IP address search key can also be added.

  When the IP address determination means 18 detects the determination result “Y” of the completion of the IP log analysis, it executes the IP log analysis result display process in step S4. In this case, the IP address determination unit 18 can display the IP log analysis result on the user terminal 10 via the Internet network 12 on a display (not shown). On the display, warning information for identifying and displaying a mismatch between the determination result of the IP address determination determination means 18 and the inquiry address information is displayed.

  “Warning information” may highlight (bold or underline) the character string of the reference address, and specify a background color that is different from the background color of the upper or lower line for the line displaying the registration number that does not match the address. By displaying, the user can easily identify.

  Further, the “warning information” may display a character string of the address of the IP address based on the determination result instead of the character string of the reference address. In short, it is possible to arbitrarily set a means for warning the user of an event where the reference address and the IP address do not match.
