Abstract: Cryptography is utilized widely in the field of information security. This paper discusses some shortcomings of cryptographyand proposes an improved method of high reliability. Based on automated fingerPrint verification system, network users can communicatewith each other safeIy without retaining the keys by themse1ves. The main idea is that saving all users' keys and their fingerPrint features inKDC (Key Distribute Center) together, one user acquires his(her) key through AFVS when he (she) needs the key, that is, the encryptedfingerprint image is transformed to KDC and compared with the user's fingerprint features, after being verified correctly the user will get itssecret key. Experimental resultS demonstrate the effectiveness of the proposed method. From thc specific utilization point, this mechanism canbe used in security of Internet communicahon, electronic commerce, govemmental organization and military fields, etc.
