Vehicle owner identity pre-authentication method based on behavior characteristics

Abstract

The invention discloses a vehicle owner identity pre-authentication method based on behavior characteristics, and the method specifically comprises the steps: collecting pressure data when different volunteers open a vehicle door through a pressure sensor, and carrying out the manual marking; preprocessing the pressure data, and training an authentication model by using the preprocessed pressure data to obtain a trained authentication model; collecting pressure data when a legal user of a vehicle opens a vehicle door for multiple times, and preprocessing the pressure data to serve as a reference sample set of the legal user; collecting pressure data when an unknown user opens a vehicle door, and preprocessing the pressure data as an authentication sample; and performing similarity comparison on the authentication sample and each reference sample in the reference sample set by using the trained authentication model, performing pre-authentication, opening the vehicle door if the pre-authentication is passed, or else, performing unlocking by using a key by the user. According to the method, the legality of the user identity is pre-authenticated by utilizing the action characteristics of the user in the door opening process, so that the user experience and the safety are improved.

Description

Technical field [0001] The present invention relates to an owner-based pre-certification method based on behavioral characteristics, belonging to the field of identity authentication. Background technique [0002] In the transportation field, the identity authentication method of the owner is mainly to unlock the vehicle using the key, and the vehicle is used to remotely unlock the vehicle using the wireless car key, and the vehicle is unlocked using a keyless entry technology. However, these technologies have a drawback: all unlocking methods need to carry additional unlocking equipment, the key is easy to be attacked by attackers, remote unlocking and keyless entry have a threat of playback attack, while keyless enters the system The signature and certificate of defects are easily attacked. Therefore, in order to be effective authentication to the owner, it is necessary to improve user experience and security, and a new identity authentication method is needed. Inventive conte...
