The reception unit 32 (see FIG. 3) accepts at least the input of the second telephone number.
The reception unit 32 further receives the second communication device information regarding the communication device using the second telephone number.

The second telephone number is a telephone number that is judged to be fraudulently used, and "second" is added as an identifier to the "telephone number" so that it can be distinguished from other telephone numbers in the present disclosure. It is crowned.

The business operator A, the business operator B, and the business operator C use the business operator A terminal 13, the business operator B terminal 14, and the business operator C terminal 15 to transfer the second telephone number to the information processing device 10 via the Internet 11. Send. The information processing device 10 can also receive a second telephone number input by using the keyboard, mouse, or the like which is the input device 26.

The second communication device information is information about the communication device 18b such as a smartphone and a mobile phone used when the second telephone number is used, like the first communication device information described above, and is the second telephone. It is obtained in cooperation with the number. The communication device 18b is the communication device 18 that was used when the second telephone number was used.

The second communication device information is, for example, the "serial number", "user information", "hardware name", and "device name (model name)" set in the communication device 18b using the second telephone number. , "Model number", etc., including information on which country / region the access came from and which time zone the access was made, and these are the same as the first communication device information.

The determination unit 33 (see FIG. 3) determines the possibility that the second telephone number is being used illegally, based on whether or not at least the second telephone number is registered in the fraudulent information database 46.
If the second telephone number matches the first telephone number registered in the fraudulent information database 46, the determination unit 33 determines that the second telephone number may be illegally used.

The determination unit 33 (see FIG. 3) determines the possibility that the second telephone number is being used illegally based on whether or not there is the first communication device information that is highly related to the second communication device information. May be good.
When the characteristics of the second communication device 18b often match the characteristics of the first communication device 18a registered in the fraudulent information database 46 and are highly related, the determination unit 33 has the second communication device 18b and the first. It is assumed that the communication device 18a can be identified with the communication device 18a, and it is determined that the second telephone number used by the second communication device 18b may be misused.

The determination unit 33 (see FIG. 3) is a case where the same telephone number as the second telephone number is registered as the first telephone number in the fraudulent information database 46, and the first communication device corresponding to the first telephone number. When the degree of correlation between the information and the second communication device information corresponding to the second telephone number is higher than the predetermined first threshold value, it is determined that the second telephone number may be misused. May be good.

The degree of correlation is the matching ratio between the first communication device information and the second communication device information, and among the features of the second communication device in the second communication device information, the characteristics of the first communication device and It shows the percentage of matches. When there are many matches between the characteristics of the first communication device and the characteristics of the second communication device, the degree of correlation is high.

Even if the second telephone number matches the first telephone number, if the correlation between the first communication device information and the second communication device information is low, the second telephone number is a history of unauthorized use in the past. However, it can be said that the possibility of unauthorized use is low now.

Therefore, the determination unit 33 determines when the second telephone number matches the first telephone number and the degree of correlation between the first communication device information and the second communication device information is higher than a predetermined first threshold value. , It is determined that the second telephone number may be misused.

As shown in FIG. 4, a "correlation score" is assigned to each of the features 1 to 24 of the first communication device, and among the features of the second communication device, a feature that matches the feature of the first communication device. If there is, the total number of "correlation scores" assigned to the characteristics of the first communication device may be used as the correlation degree of the second communication device.

As for the "correlation degree", the same score may be assigned to different "characteristics of the communication device", and it is important for estimating whether or not the telephone number is being used illegally. The higher the score, the higher the score may be assigned.

For example, the first threshold value is set to "6".
When the "serial number" of "feature 1" in the second communication device information is "SN.GQTYV ***", it matches the "serial number" of "feature 1" of the first communication device information. Therefore (see FIG. 4), the "correlation score" of the second communication device information is "10", which exceeds the first threshold value of "6". Therefore, the determination unit 33 determines that the second telephone number may be misused.

If the "hardware name" of "feature 3" and the "model number" of "feature 5" of the second communication device information match those of the first communication device information, the second communication The "correlation score" of the device information is "8", which exceeds the first threshold value of "6". Therefore, the determination unit 33 determines that the second telephone number may be misused.

In addition, among the second communication device information, "device name (model name)" of "feature 4", "screen size" of "feature 12", "screen resolution" of "feature 13", and "feature 15" When only the "language used" of "" matches that of the first communication device information, the "correlation score" of the second communication device information is "6" and does not exceed the first threshold value "6". Therefore, the determination unit 33 does not determine that the second telephone number may be misused.

The determination unit 33 (see FIG. 3) determines the degree of correlation with the second communication device information even when the same telephone number as the second telephone number is not registered as the first telephone number in the fraudulent information database 46. If there is information on the first communication device that is higher than the second threshold value of, it may be determined that the second telephone number may be misused.

That is, even if the second telephone number does not match the first telephone number registered in the fraudulent information database 46, the second telephone if the degree of correlation between the first telephone device information and the second telephone device information is high. It is determined that the number may be misused.

For example, the second threshold value is set to "9".
Of the second communication device information, the "user information (email address)" of "feature 2" is "aaa123@pmail.com", and the "keyboard input method" of "feature 7" is "pin-in input, kana input". In the case of "none", it matches the "user information (email address)" of "feature 2" of the first communication device information and the "keyboard input method" of "feature 7" (see Fig. 4), so the second communication device The "correlation score" of the information is "10", which exceeds the second threshold "9".

Therefore, the determination unit 33 correlates the first communication device information with the second communication device information even when the same telephone number as the second telephone number is not registered as the first telephone number in the fraudulent information database 46. The degree is high, and it is determined that the second telephone number may be misused, assuming that the first communication device and the second communication device can be identified with each other.

In addition, among the second communication device information, only the "hardware name" of "feature 3", the "battery level" of "feature 6", and the "communication company" of "feature 16" are the first communication device information. If it matches, the "correlation score" of the second communication device information is "9" and does not exceed the second threshold value "9".

Therefore, in the determination unit 33, the first telephone number and the second telephone number do not match, and the degree of correlation between the first communication device information and the second communication device information is not high, so that the first communication device and the second communication device are the first. 2 It is not determined that the second telephone number may be misused because it cannot be identified with a communication device.

The output unit 34 (see FIG. 3) is information indicating that the second telephone number is a telephone number that may be illegally used when the second telephone number is registered in the fraudulent information database 46. Is output.

Further, the output unit 34 may output the information related to the second telephone number when the determination unit 33 determines that the second telephone number may be misused.

The output unit 34 outputs the information regarding the second telephone number to the business operator via the information processing terminal used by the business operator. Further, the output unit 34 can also output the information regarding the second telephone number by using the monitor, the printer, the speaker, or the like of the output device 27 of the information processing device 10.

When the receiving unit 30 receives fraudulent information from one of a plurality of different businesses, the notification unit 35 (see FIG. 3) receives the fraudulent information to other businesses other than one business. Send and notify the fraudulent information.

For example, when the fraudulent information is received from the business operator A, the notification unit 35 transmits the fraudulent information received from the business operator A to the business operator B and the business operator C to notify the business operator B.

Next, the data structure of the fraudulent information database 46 will be described with reference to FIG. The fraudulent information database 46 creates a database of fraudulent information as a blacklist and stores it. The fraudulent information includes the first telephone number and the first communication device information.
