Problems solved by technology

The only way to achieve fast login is by remembering the password, but there is a great risk that other users can successfully enter the system to view relevant information by remembering the password, resulting in information leakage
Especially in cars, it is very inconvenient to use digital passwords and pattern passwords to manually enter; digital passwords and pattern passwords can only be logged in quickly by remembering the passwords, which has many risks; different users need to set different passwords, Every time you log in, you have to re-enter the password. This method cannot be widely used in cars, and the operability and comfort of the driver are seriously affected.

Abstract

The invention discloses a voiceprint recognition automobile login method. The method includes the following steps that a voice collector is used for collecting voice information, and a login voice file is obtained; voiceprint features of the login voice file are extracted; the voiceprint features are compared with a standard voiceprint digital file, a login numerical value string corresponding to the login voice file is obtained, and each voiceprint feature of the standard voiceprint digital file corresponds to one specific numerical value; the login numerical value string is compared with registered numerical value strings in a database for identity authentication, and an authentication result is obtained; the identity of a user is confirmed according to the authentication result; voice of the user is collected, the features of voiceprints of the voice are extracted, the voiceprint features are converted into the numerical value string, the numerical value string is compared with the numerical value strings in the database for identity authentication, the identity of the user is confirmed, and whether the user can log in to an automobile control system or not is judged.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a voiceprint recognition car login method. Background technique [0002] At present, when users log in to ID (ID is the abbreviation of identity in English, meaning identification number. It is also called serial number or account number), they basically log in through passwords, such as digital passwords, pattern passwords, etc. to achieve ID login. The only way to achieve fast login is by remembering the password, but there is a great risk that other users can successfully enter the system to view relevant information by remembering the password, resulting in information leakage. Especially in cars, it is very inconvenient to use digital passwords and pattern passwords to manually enter; digital passwords and pattern passwords can only be logged in quickly by remembering the passwords, and there are many risks in this method; different users need to set different passwords, ...
