Secure login method and apparatus

Abstract

The present invention discloses a secure login method. The method comprises: obtaining first voice data generated by a user by reading a preset feature text, and determining a voiceprint feature of the first voice data; obtaining second voice data generated by a user by reading a random text, and determining the voiceprint feature of the second voice data; and determining the matching degree of the voiceprint feature of the first voice data with the voiceprint feature of the second voice data, and when he matching degree is greater than the preset matching degree threshold, allowing the user to login. The present invention also discloses a secure login apparatus.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a secure login method and device. Background technique [0002] With the popularity of mobile terminals, the security of mobile terminals has attracted more and more attention; usually, users will lock mobile terminals when they are not in use, and mobile terminals themselves can also be automatically locked according to the settings. In this way, Non-secure users cannot operate the mobile terminal; after the mobile terminal is locked, security login is required for normal operation, also known as unlocking; some software applications with high security requirements, such as online banking software, also require security login. common secure login methods include password unlocking and fingerprint unlocking. [0003] With the development of technology, the application of voice input technology in secure login of mobile terminals has become a trend; especiall...

Problems solved by technology

[0004] However, the simple voice recognition technology, which only matches the voice sound waves, is far from meeting the requirements of protecting user privacy; at present, the industry basically adopts the following methods for voiceprint security login: start the voice recognition mode, listen to voice commands; match and save If the voice commands in the mobile phone and the voice commands heard reach a certain degree of matching, the mobile phone will be logged in safely; if the matching degree is not reached, the mobile phone cannot be logged in safely

At the same time, the single security login entry also caused troubles for users. The security login entry is easy to be obtained by people around, and it is not interesting.

[0005] The existing technology only matches specific voice commands. When affected by the environment and other aspects, the fluctuation of the matching rate will increase, which will affect the matching results; moreover, it does not protect the user's safety from the user's own characteristics. If the voice command is forgotten, it will not be safe. Login; a single security login entry is easy to be deciphered and intercepted by others; it is not associated with the user’s voiceprint characteristics, so it is easy to imitate and be deciphered; repeating the same security login voice command for a long time is boring, uninteresting, and easy to cause User disgusted
