The embodiment of the invention provides an identity verification method and device and equipment. The method comprises the steps that partial coding processing is performed on a first image of a userto obtain first partial coding data of the first image, wherein the partial coding processing comprises filtering processing, data blocking processing and data block prediction processing; first feature information of the first image is extracted from the first partial coding data; pre-stored ciphertext data is decrypted to obtain second feature information, wherein the ciphertext data is data obtained after partial coding processing, feature extraction and data encryption processing are performed on a second image; and the first image is verified according to the first feature information and the second feature information. The identity verification method and device and the equipment are used for improving the security of user identity verification.
Description
technical field [0001] The embodiments of the present invention relate to the field of image technology, and in particular, to an identity verification method, device and equipment. Background technique [0002] Currently, in various application scenarios (eg, access control systems, payment systems, etc.), user images (eg, face images, etc.) can be used for identity verification. [0003] In the prior art, before the user's image can be used for authentication, registration is required. When the user registers, the terminal device (for example, the device corresponding to the access control system, the device corresponding to the payment system, etc.) acquires the image information of the user, and stores the image information of the user. When the user is authenticated, the terminal device collects the user's image information through the camera, and compares the collected image information with the pre-stored image information. If the similarity between the collected ima...
