Abstract: Provided is technology for enabling an ordinary user to generate a virtual currency that is data created as crypto cash in the true sense of the word. A user ID and amount information that are input to a user terminal by a user are sent from the user terminal to a settlement device (S913). Upon receiving the user ID and amount information, the settlement device performs a credit determination (S922), and transmits permission information to the user terminal (S923). At the user terminal, upon receiving the permission information, original data that combines the user ID and the amount information is generated (S915), the original data is encrypted and thereby converted to virtual currency encryption data (S916), and virtual currency data including the virtual currency encryption data is generated (S917). The authenticity of the virtual currency data is guaranteed by the fact that the settlement device which received the virtual currency data could decrypt the virtual currency encryption data (S925).

Abstract: Provided is a data structure of virtual currency data with high safety. The virtual currency data, which is used in combination with a settlement device that accepts settlement when the virtual currency data is received from a predetermined device via a network and when predetermined conditions are satisfied, includes virtual currency encryption data which is data generated by encrypting, according to a predetermined encryption method, original data including at least amount information that is information for specifying a monetary value of the virtual currency data, and by further extracting characters, in conformity with a predetermined rule, from a character string obtained by the encryption.

Abstract: A technique of preventing a man-in-the-middle attack is proposed. An internet banking system includes a user terminal and a settlement device that can communicate with each other via a network. The user terminal generates original data containing instruction data related to an instruction to be executed by the settlement device (S802), encrypts the original data into encrypted instruction data (S803), and transmits the encrypted instruction data to the settlement device (S805, 901). The settlement device decrypts the encrypted instruction data to returns the encrypted instruction data to the original data (S902), and executes an operation specified by the instruction data contained in the original data (S904).

Abstract: A technique for preventing a man in the middle attack is proposed. A security gate system includes an admission card and a security gate apparatus. The admission card has condition data that is data for specifying a condition to be satisfied when or before or after encrypted authentication data are transferred from the admission card to the security gate apparatus. When a user attempts to enter a building, authentication data including condition data are generated in the admission card 100 (S802), and encrypted into encrypted authentication data (S803). The encrypted authentication data are transmitted from the admission card to the security gate apparatus (S804, S904), and decrypted to be returned to the authentication data (S905). The security gate apparatus performs authentication determination which is a determination as to whether a condition specified by the condition data included in the authentication data is satisfied (S906), and opens a gate plate when a determination result is positive (S907).

Abstract: An authentication technology with far higher safety than the technology using a general one-time password is provided. A client and a server both have the function to generate the same solution under the same condition. The client creates a 20-digit first solution including alphabetical characters and numbers (S1002), generates a partial solution obtained by extracting a part of the solution according to a certain rule (S1003), and sends the partial solution to the server with identification information, which is a user ID (S1004). The server receives them (S2001), generates a solution (S2002), and generates a partial solution (S2003). When the partial solution generated by the server matches the partial solution sent from the client, the server authenticates the client to be valid.

Abstract: A safer settlement system as an alternative to a settlement system using a credit card is provided. The settlement system has a user terminal, a settlement device, and a settlement terminal. First, the user terminal receives inputting of a user ID, a password, and money amount information specifying a money amount (S912), and transfers the same to the settlement device (S913). The settlement device performs credit determination (S922), generates provisional permission information if credit is possible (S923) and transfers the same to the user terminal (S924). The user terminal generates a one-time password (S915). The one-time password is input to the settlement terminal (S931). If the one-time password transferred from the settlement terminal to the settlement device is same as a one-time password produced by the settlement device (S926), the settlement device authorizes user's payment (S927).
