Abstract
The owner sameness confirmation system determines whether or not the owners of two terminals (A,B) are the same. The terminals (A,B) store identity confirmation information stored in association with electronic certificates issued to the terminals by authentication station servers (A,B). The terminal (A) transmits information obtained by encrypting the identity confirmation information of the owner through homomorphic encryption to the terminal (B). The terminal (B) transmits response encrypted information including information obtained by encrypting the identity confirmation information of the owner of the terminal (B), as a response to the terminal (A). The terminal (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.
