Title:
SECURITY DEVICE FOR DATABASE ACCESS
Document Type and Number:
Japanese Patent JP3614638
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simply and also surely perform authentication by storing a temporary key in a user data file, also sending only a password or the password and a user's ID to a client device side and finishing an online session to a database.
SOLUTION: A server device outputs a key generation command to a key generator (S5a) if a received collation result shows the coincidence (S4). If it does not coincide, it rejects log on (S5b). The key generator produces a temporary key that consists of optional character/numeric character/symbol based on it (S6). The server device which receives the produced temporary key stores it together with a user ID in a temporary storage region (S7) and also stores the temporary key in the key storage region of the corresponding user ID of a user data file (S8). Also, the server device sends the temporary key and the user ID to a client device side and allows access to a database (S9).
