Embodiment Construction

[0016] The invention is a fingerprint-based dynamic password network authentication scheme. By partially modifying the existing general network password login system, the entire system can realize user login by fingerprint.

[0017] Hardware composition:

[0018] (1) Install a dedicated fingerprint collection head for each PC that needs to use fingerprints to log in;

[0019] (2) A server for fingerprint identification is installed in the whole system.

[0020] Software composition:

[0021] (1) Server software: Send a random character string to the client and use it to accept the fingerprint identification request. After the fingerprint identification is passed, the dynamic password is sent to the requesting client;

[0022] (2) Client software: collect fingerprints and perform feature extraction, and send the extracted features, user ID and a random character string to the server, and use the dynamic password returned by the server to complete the login.

Abstract

The present invention relates to a fingerprint based dynamic cipher network identity authentication system and its implementation method. Said invention includes fingerprint identification server mounted in the system and customer machine matched with fingerprint collector. Its implementation method includes the following steps: the fingerprint identification server can down-send a random character string to customer terminal and is used for receiving fingerprint identification request, after the fingerprint identification is passed, the dynamic cipher can be sent to the customer sending request, the customer terminal can acquire fingerprint and make characteristic extraction, and can send the extracted characteristics, user ID and a random character string to server and use dynamic cipher back-transferred by server so as to implement logging.

Description

1. Technical field: [0001] The invention relates to a network identity authentication system, in particular to a fingerprint-based dynamic password network identity authentication system and its realization method. 2. Background technology: [0002] The most common way to log in the current network system is to use the password mode, that is, the user can log in by entering his user name and password. In addition to problems such as easy forgetting and complicated input, traditional passwords also have problems such as too short password length, too simple password characters, and users do not change passwords for a long time, which are easy to reduce and damage the system. safety. The dynamic password has the advantages that the traditional password does not have. It can be randomly generated without repetition every time according to the requirements. The content of the password is completely irregular and the length can be set according to the needs of the user, thereby ...
