Target certificate detection method and device and terminal equipment

Abstract

Embodiments of the invention provide a target certificate detection method and apparatus, and a terminal device. The method comprises the steps of obtaining a face image of a target object and a target image containing a target certificate; Respectively acquiring first feature data and second feature data according to the picture data; Calling the first MPC node to take the first feature data andthe second feature number as input data; a second MPC node preset in the server takes a data template of the face feature data as input data; carrying out operation according to preset rules, and detecting whether the target certificate meets a preset requirement or not; According to the scheme, the first MPC node of the terminal equipment and the second MPC node of the server are called to take respective owned data as input; The operation is performed according to the preset rule to determine the authenticity of the target certificate, so that the terminal equipment or the server is prevented from knowing the data owned by the opposite side, and the technical problem that the data privacy of the user cannot be protected in the detection process is solved.

Description

technical field [0001] The present application relates to the technical field of security inspection, and in particular to a detection method, device and terminal equipment of a target certificate. Background technique [0002] In many scene applications, the authenticity of the certificate held by the object to be detected is often determined by using the face photo of the object to be detected and the ID photo on the certificate held by the object to be detected. [0003] For example, in the security check scene at the airport, the face photos of the passengers currently passing the check will be taken through the security check equipment, and the passports held by the passengers currently passing the check will be scanned at the same time; The pictures obtained by scanning the passports are based on facial feature recognition to detect whether the passports held by passengers who have passed the inspection are forged passports. Only when it is confirmed that the passport...
