本人認証インフラストラクチャシステム
Document Type and Number:
Japanese Patent JP4097623
Kind Code:
B2
Abstract:
There is disclosed a user identification infrastructure system which does not depend on a user identification device (token) and which sets user identification to be independent of an application (Ap) which requests or uses the user identification and to which Ap-related data can easily be added. A virtual token memory (VETM) service server stores virtual region management information (a user ID, a user access key and/or a user encryption/decryption key, an Ap access key and/or an Ap encryption/decryption key and information of a data file storage place): acquires an Ap ID from a VETM corresponding client by an operation of a VETM corresponding Ap; acquires information of the file storage place based on the user access key and/or the user encryption/decryption key uniquely derived and produced from a user identifier or the like received from the token and the Ap ID; decrypts the information with the Ap encryption/decryption key; and/or accesses the information with the Ap access key.
