User registration and logon method by combining speaker speech identity authentication and account code protection in network games

Abstract

The invention discloses a user registration and logon method by combining speaker speech identity authentication and account code protection in network games. A client receives and processes a speech signal, and a server carries out speaker speech identity authentication through a speech template. The method adopts speaker text related speech identity authentication related and account code protection, and has an anti-theft function. At the client, the method comprises: dual-cache sound storage scheme: acquiring and storing a sound signal; and end-point detection and feature extraction: detecting end points in the sampled sound signal to determine start/end frames of an effective speech signal, and extracting feature parameter (linear prediction cepstrum factor) of each frame. At the server, the method adopts dynamic programming to compute matching degree of speaker speed parameter and speech template. If the account code is thieved, since the vocal process and vocal organ of an illegal user are different from a registered user, the illegal user can not easily pass through the speech identity authentication. Even if the illegal user logs on by copying the account code and speech parameter, the server can compare with the prestored speech parameter and detect parameter conformity, causing speech identity authentication failure. After having successfully registered the account code, the user has to register a speech code by speaking and repeating the same text content until enough quantity of speech templates are successfully generated. The user needs to speak the speech code to log on. After the speaker speech identity authentication is successful, the server can confirm a user logon success immediately or after the user has input the correct account code; and after the speaker speech identity authentication fails, the server can determine a user logon failure immediately or confirm a user logon success after requiring the user to input the correct account code.

Description

technical field [0001] The invention relates to a network security verification method in network games, especially a user registration and login method. Background technique [0002] At present, in online games, the account number and password for user login are stolen more and more seriously. There are many account hacking Trojan horses on the Internet that use keyloggers, screenshots, memory scans, etc. to steal other people's account passwords, illegally obtain virtual property, and cause economic losses and mental harm to the stolen users. [0003] In order to protect the user's account and game security, some online game companies have launched security products to protect the account and game security. On the one hand, although users use security products, users still have the risk of account passwords being modified and suffering losses after account passwords are stolen; on the other hand, these security products undoubtedly increase users' expenses.
