Abstract
The owner sameness confirmation system determines whether or not the owners of two terminals (A,B) are the same. Authentication station servers (A,B) store electronic certificates issued to the terminals and identity confirmation information of the owners of the terminals in association with each other. The authentication station server (A) transmits information obtained by encrypting the identity confirmation information of the owner of the terminal (A) through homomorphic encryption and the electronic certificate of the partner terminal (B) to the authentication station server (B). The authentication station serverB transmits response encrypted information including information obtained by encrypting the identity confirmation information of the owner of the terminal (B) as a response. The authentication station server (A) decrypts the response encrypted information and determines the sameness of the owners based on whether or not the decryption result matches a predetermined value.
