This optional function is a function that enables decryption from electronic tally to registered identification information only between two parties, the applicant terminal device 10 and the agent terminal device 20, and the management server 30 divides the third tally. The temporary tally A and the temporary tally B are created, the temporary tally A is combined with the first tally, the temporary tally B is combined with the second tally, and each is transmitted to the applicant terminal device 10 and the agent terminal device 20. Decryption is executed by agreement between the applicant terminal device 10 and the agent terminal device 20.

9 and 10 are flowcharts showing a series of processes in the optional function.
After the electronic tally creation means of the management server 30 creates the first tally, the second tally, and the third tally (S301), the third tally re-dividing means re-divides the third tally into the temporary tally A and the temporary tally B ( S302). The provisional tally creation means combines the provisional tally A with the first tally to create the first tally with provisional tally, and combines the provisional tally B with the second tally to create the second tally with provisional tally (S303). The provisional tally storage means stores provisional tally in the tally database 33 (S304). Then, the tally transmission means transmits the first tally with provisional tally to the applicant terminal device 10 (S305), and the applicant terminal device 10 receives the first tally with provisional tally (S306). The second tally with provisional tally is transmitted to the agent terminal device 20 (S307), and the agent terminal device 20 receives the second tally with provisional tally (S308).

  FIG. 10 shows processing when the applicant wishes to view the registration identification information. That is, a browsing request is transmitted from the applicant terminal device 10 to the agent terminal device 20 (S401). The agent terminal device 20 receives the transmitted browsing request (S402). It is determined whether or not the agent approves browsing (S403), and when browsing is permitted, browsing permission data is returned to the applicant terminal device 10 (S404). In the applicant terminal device 10, the browsing permission data receiving unit receives the browsing permission data (S 405), and the second tally acquisition unit with provisional tally acquires the second tally with provisional tally from the agent terminal device 20 ( S406). Then, the registration identification information decoding means extracts and collates the first tally with provisional tally stored in the storage unit with the second tally with provisional tally acquired from the agent terminal device 20, and stores it in the registration identification information. Decryption is performed (S407). When the agent wishes to view the registration identification information, the positional relationship between the applicant and the agent in FIG. 8 is reversed.

  That is, in the optional function, the temporary tally A and the temporary tally B obtained by re-dividing the third tally are combined with the first tally for the applicant and the second tally for the agent and transmitted, and they are collated at the time of decoding. Thus, the registration identification information can be decrypted only by agreement (tally) between the applicant and the agent. Therefore, decryption can be performed without requiring the management server 30, which contributes to improvement in convenience.

  In the normal state, only the first tally and the second tally are visualized as the first tally with the tally and the second tally with the tally, and the tally A and the tally B are configured as invisible data. That is, when the first (second) tally stored in the storage unit in the applicant (agent) terminal device 10 is seen, the applicant terminal device 10 receives the first tally, and the agent terminal device 20 receives the first tally. The tally tally A and the tally tally B are formed as secret data (invisible) without changing to the state of receiving the tally.

  This is because the registration identification information is not assumed to be decrypted only between the two parties, but decryption using the third tally of the management server 30 is preferable from the viewpoint of security. However, for example, if an unexpected situation such as a failure of the management server 30 occurs and the applicant or the agent needs the registration identification information, the third tally stored in the management server 30 is obtained. There is a possibility that it cannot be decrypted because it cannot. The optional function makes it possible to cope with such a case, and decryption is possible only between two parties.

  Further, in the optional function of the present embodiment, the two parties are described as the applicant and the agent, but it is also possible to change to the applicant and the management server, and the agent and the management server. That is, the registration identification information can be decrypted if there is agreement between the two parties.

  The present invention can be used when an applicant and a judicial scrivener make an online application for real estate registration at a registry office.
