ELECTRONIC LOCAL GOVERNMENT SHARED SERVER USING ENCRYPTION DATA CONVERTER, AND ELECTRONIC LOCAL GOVERNMENT TERMINAL USING ENCRYPTION DATA DECODING DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a means of eliminating "security holes" in an electronic local government shared server, and safely relaying data between terminals of different encryption protocols, in terms of security. PSOLUTION: An electronic application system is constructed of the local government shared server 1, a plurality of terminals for residents 3, and a plurality of local government terminals 4. The local government shared server 1 is constructed of a first network connection means 11, an encryption data converter 2, a reference table producing means 12, a reference table storage means 13, an encryption data storing means 14, a second network connecting means 15, a reference table search means 16, and a data access control means 17. The encryption data converter 2 converts encryption data, based on an external protocol into those based on an internal protocol and secures confidentiality of clear text data once decoded in this procedure. In correspondence to a single application data, a reference code, to be referred by the local government terminal 4 before the acquisition of the application data, is created.
