Abstract: A camera authentication method and a control apparatus are provided, and are applicable to an identity authentication of an on-board camera in the autonomous driving field. The method includes: obtaining one or more frames of a first image shot by a to-be-authenticated camera; determining one or more light intensity offset values of N photosensitive units based on the one or more frames of the first image; determining a matching degree between the light intensity offset values of the N photosensitive units and a preset N-dimensional vector; and if the matching degree meets a preset condition, determining that authentication of the to-be-authenticated camera succeeds, where the N photosensitive units are in a photosensitive layer of the to-be-authenticated camera, and the photosensitive layer includes M photosensitive units, where N≤M. This technical solution is used to improve camera security.

Abstract: A smart lock unlocking method and a related device are provided, and may be specifically applied to an intelligent vehicle and a self-driving vehicle, to implement an unlocking function of a smart lock of the vehicle. The method includes: A terminal device monitors a distance change trend between the terminal device and an intelligent device, where the intelligent device includes a smart lock (S401). If the terminal device determines that the terminal device is approaching the intelligent device and a distance between the terminal device and the intelligent device is less than a first distance threshold, the terminal device enables an identity authentication process between the terminal device and the intelligent device (S402). The terminal device unlocks the smart lock when identity authentication between the terminal device and the intelligent device succeeds (S403).

Abstract: This disclosure provide a vehicle control method. A first terminal device obtains first biometric information of a first user, generates a first key based on the first biometric information and identifier information of the first terminal device, and generates first verification information based on the first key. Further, the first terminal device sends the first verification information to an in-vehicle device. When successfully verifying the first verification information, the in-vehicle device controls a vehicle to start. If the first user loses the first terminal device, an unauthorized user that obtains the first terminal device cannot control the vehicle based on only the identifier information of the first terminal device. Because different users have different biometric information, a key generated by the first terminal device is different from the first key, and the in-vehicle device cannot control the vehicle to start. This improves vehicle security.

Abstract: An electronic device displays one or more pieces of content on a display screen. k face images are obtained by using a camera during display of the content. t facial expression parameter values are determined according to the obtained k face images. If a matching degree of the t facial expression parameter values and a first preset reference sequence is not less than a first preset threshold, and if face matching according to at least one of the obtained k face images succeeds, determine that a face verification result is success.
