Evidence preservation system and evidence preservation method

摘要

PROBLEM TO BE SOLVED: To generate data which is established as evidence of explanation of important matters while protecting personal information. A preferred aspect of the present invention is an evidence preservation system that processes recorded data of a video conference between a first terminal and a second terminal communicating via a network. This system includes a processing unit that can use an identity verification unit. The processing unit causes the identity verification unit to collate the image data of the first user himself / herself acquired by the first terminal with the certificate with an image of the first user. When the matching of the image of the first user is successful, the processing unit performs the first private key, the first public key, the first self-signed certificate, and the first of the first user. The first information for recovering the first private key is generated from the image data of one user himself / herself. [Selection diagram] FIG. 6A
