  The content information receiving unit 302 receives content information from the number management server device 200.

  The number management server device 200 includes a request reception / response unit 201, a number payout unit 202, a number management unit 203, and a number inquiry unit 204.

  The request reception / response unit 201 receives a request signal from the number issue client device 100 and transmits a content identification number. The request reception / response unit 201 receives a request signal from the number inquiry client device 300 and transmits content information.

  The number payout unit 202 pays out a content identification number that is valid for a certain period in response to a request signal from the number payout client device 100. Specifically, the number payout unit 202 pays out a number different from other content identification numbers for a predetermined digit in the content identification numbers, and randomly pays digits other than the predetermined digits. . Alternatively, the number payout unit 202 pays out consecutive numbers for a plurality of predetermined consecutive digits in the content identification number, and randomly discharges digits other than the predetermined consecutive digits.

  Also, the number issue unit 202 registers the content information received from the number issue client device 100 and the content identification number in the number management unit 203 in association with each other.

  The number management unit 203 manages the content identification number issued by the number issuing unit 202 in association with the content information, and manages the expiration date for each content identification number. Specifically, the number management unit 203 monitors the delivery order of the content identification numbers, and manages the expiration date of each content identification number based on the difference in the expiration date from the content identification number registered immediately before.

  The number management unit 203 deletes the corresponding content identification number from the storage unit (not shown) when the expiration date has passed. The storage unit refers to a database, and specifically, may be an internal storage device such as a RAM or an external device such as an HD.

According to the recording medium holding such a program, the program can be easily stored, transported, sold, and the like.

(Number management method)
Next, the number management method according to the present embodiment will be described with reference to FIGS.

  First, in step S101 in FIG. 2, the number issue client device 100 transmits content information linked to the content identification number to the number management server device 200.

  Next, in step S102, the number management server device 200 pays out a content identification number associated with the received content information. At this time, the number payout unit 202 of the number management server device 200 uses a random number to randomly pay out the number of digits and the number of each digit so that the content identification number to be paid out cannot be easily estimated. Also, in order not to pay out the same number as the content identification number that has been paid out in the past, it is confirmed that the randomly paid number and all the numbers that have expired in the past have been matched. In this case, it is necessary to reissue the number, and it takes time to pay out the number. For this reason, in order to avoid paying out the same content identification number as the previously paid content identification number, the number payout unit 202, as shown in FIG. The content identification number is paid out so as to eliminate randomness and intentionally not be the same number as other content identification numbers. For example, in FIG. 3, the number of digits is at least 14 and the third, seventh, tenth, eleventh and fourteenth digits are intentionally paid out. Then, for example, as shown in FIG. 4, the third digit, the seventh digit, the tenth digit, the eleventh digit, and the fourteenth digit are respectively changed to the thousands, the first place, the tens place, and the tenth place of the content identification number. Used for hundreds and hundreds. In addition, the number management server device 200 gives an upper limit to the number of content identification numbers that can remain valid depending on the performance of the system. Do not give out the identification number.

  In addition, when a content information inquiry request to be described later is received, it is necessary to collate all paid-out content identification numbers within the validity period with the inquiry number in order to acquire content information associated with the corresponding content identification number. , Processing time and processing time are increased. For this reason, the number payout unit 202 of the number management server device 200 pays out a plurality of specific digits with consecutive numbers, and randomly pays out other digits. For example, as shown in FIG. 5A, the first digit and the second digit are paid out with consecutive numbers, and the third digit and the fourth digit are randomly given out. At this time, the number of content identification numbers that can be held by the number management server device 200 can be considered as a cycle in which the number that increases sequentially returns to the original number once. FIG. 5B shows a sequentially arranged number and a content identification number corresponding to the number.

  Next, in step S <b> 103 of FIG. 2, the number management server device 200 transmits the content identification number associated with the content information to the number payout client device 100.

  Next, in step S104, the number management unit 203 of the number management server device 200 manages the content identification number assigned in step S102 and the content information in association with each other. Then, the number management unit 203 manages the expiration date for each content identification number that has been paid out, and deletes the content identification number that has expired. At this time, if expiration time management is performed for all the content identification numbers that have been paid out, the processing load on the machine increases as the number of content identification numbers that have been paid out increases, and the number payout time and content information Inquiry response time becomes longer. Therefore, expiration date management is performed by the following method shown in FIG.

  First, the number management unit 203 stores the content identification number data in a chain table in the order in which the numbers are issued. For this chain table, a FIFO (First-in First-out) method for retrieving data stored in a certain place in the order in which it was stored may be used.

  Next, a content identification number registration method will be described. The number management unit 203 receives a number issue request from the number issue client device 100 (S201), and if there is no registration data before, sets the expiration date (here 60 seconds) as a timer value as it is. Then, an expiration date (60 seconds here) is set in the total timer value. Next, the number management unit 203 issues a number to the number issue client device 100 via the number issue unit 202 and the request reception / response unit 201 (S202). Further, after 10 seconds from the state of step S202, when the number management unit 203 receives a number issue request from the number issue client device 100 (S202), since the registration data exists before, the expiration date (in this case, 60 A value obtained by subtracting the total timer value (here, 50 seconds) from (second) (here, 10 seconds) is set as the timer value. Then, an expiration date (60 seconds here) is set in the total timer value. Next, the number management unit 203 issues a number to the number issue client device 100 via the number issue unit 202 and the request reception / response unit 201 (S204). Further, after 10 seconds have elapsed from the state of step S204, when the number management unit 203 receives a number payout request from the number payout client device 100 (S205), since there is registration data before, an expiration date (in this case, 60 A value obtained by subtracting the total timer value (here, 50 seconds) from (second) (here, 10 seconds) is set as the timer value. Then, an expiration date (60 seconds here) is set in the total timer value. Next, the number management unit 203 issues a number to the number issue client device 100 via the number issue unit 202 and the request reception / response unit 201 (S206).

  Next, a method for monitoring the content identification number will be described. The number management unit 203 monitors the validity period of the content identification number data while performing the registration process described above. That is, as shown on the right side of FIG. 6, the number management unit 203 monitors the top content identification number data in a specific second α cycle, and subtracts the timer value and the total timer value according to the elapsed time. . If the timer value of the top data becomes 0 as a result of the subtraction, the corresponding data is deleted. Next, the data registered next to the deleted head data is set as the head data, the head data is monitored, and the timer value and the total timer value are similarly subtracted. If the timer value of the top data becomes 0 as a result of the subtraction, the corresponding data is deleted. These processes are performed until the registered data becomes zero.

  On the other hand, in step S <b> 105 of FIG. 2, the number inquiry client device 300 transmits the content identification number to the number management server device 200.

  In step S <b> 106, the number inquiry unit 204 of the number management server device 200 acquires content information corresponding to the content identification number from the number management unit 203. At this time, since the content identification number is issued with a plurality of specific digits as consecutive numbers and other digits are randomly assigned, the number management unit 203 does not require much processing time and the content Content information corresponding to the identification number can be found.

  In step S107, the number management server device 200 transmits corresponding content information to the number inquiry client device 300.

(Function and effect)
According to the number management server device 200 and the number management method according to the present embodiment, among the content identification numbers, a predetermined digit is a different number from the other content identification numbers, and a digit other than the predetermined digits Can be paid out randomly. For this reason, by making the specific digit of the content identification number different from other content identification numbers, it is not necessary to confirm matching with all content identification numbers that have been issued in the past, and the processing load can be reduced. In addition, the processing speed can be improved.

  In addition, according to the number management server device 200 and the number management method according to the present embodiment, among a plurality of predetermined consecutive digits in the content identification number, a consecutive number is assigned and a plurality of predetermined consecutive numbers Digits other than digits can be paid out randomly. For this reason, by managing with the consecutive numbers paid out, when the content information is inquired from the content identification number, the content identification number can be collated at high speed, and the processing load can be reduced. Specifically, when content information is inquired from the content identification number, the content identification number can be searched or acquired when the content identification number exists.

  Further, according to the number management server device 200 and the number management method according to the present embodiment, the number management that receives content information from the client device that uses the content and transmits the content identification number corresponding to the content information to the client device. The server device can monitor the delivery order of the content identification numbers, and manage the expiration date of each content identification number based on the difference of the expiration date from the content identification number registered immediately before. For this reason, the expiration date of each content identification number can be managed and the processing load can be reduced only by monitoring the head data registered earliest in a specific cycle and updating the timer value. Specifically, the expiration date of each content identification number can be managed by subtracting the timer value and the total timer value.
