Authentication Method for Information Retrieval System

Abstract

The invention discloses an authentication method of an information retrieval system. The authentication method comprises the following steps: A, initializing; B, authenticating; C, authenticating pass. When personal information is logged in a retrieval webpage, a user changes a password as the password is more complex and inconvenient to memorize for the user. The authentication method disclosed by the invention can randomly draw previous stored passwords of the user, remind the user and force the user to recall the previous designed passwords; thus, the user does not need to set a password again, and user experience degree is improved.

Description

technical field [0001] The invention relates to a method for user identity authentication, in particular to an authentication method for an information retrieval system. Background technique [0002] Generally speaking, information retrieval is a process of finding and retrieving user-related information from a large amount of information storage. In the process of performing information retrieval, it is important to retrieve all the information that the user needs (that is, completeness is important), and it is also important to limit the retrieved information that is irrelevant to the user (that is, selectivity is also important). These aspects are usually defined in terms of recall (completeness) and precision (selectivity). In many information retrieval systems, it is very necessary to achieve good performance in terms of both recall and precision. [0003] The current information search needs to go through the visit of the webpage to further search for information. At...

[0003] The current information search needs to go through the visit of the webpage to further search for information. At present, when visiting the webpage, it is mainly through the process of requesting webpage access, and judge whether to give the webpage login authority according to the user name and password information filled in by the user PC, and , Now log in to the system and set the user PC to input 3 times, the login system will automatically lock the account of the user PC, and the user PC has to go to the webpage linked by the login system to unlock it. Although the login system improves security, its user experience is reduced. , and when logging in to a webpage, the passwords saved in the webpage are generally more complex and difficult to remember
