Abstract

The embodiment of the invention provides an image information processing method and device for protecting privacy and an identity authentication method and device for protecting privacy. One specificembodiment of the image information processing method comprises the steps of obtaining a feature character string formed based on image features of a biological feature image of a user; allocating a corresponding shift number to the feature character string; according to the shift number, performing shift operation in a predetermined direction on the feature character string to obtain valid verification information in the current period; and respectively sending the verification information and the shift number to the client. Therefore, the feature character string subjected to the shifting operation is used as the effective verification information in the current period, so that the client stores the verification information, and the risk caused by loss of the biological feature data canbe reduced. Besides, when the verification information is sent, the shift number is also sent, so that the client can realize identity verification of the user subsequently according to the verification information and the shift number.

Description

technical field [0001] The embodiments of this specification relate to the technical field of data security, and in particular, to a privacy-protecting image information processing method and device, and a privacy-protecting identity verification method and device. Background technique [0002] With the continuous improvement of the operation capability and storage capacity of the terminal equipment, some functions of the server side can be implemented on the terminal side. For example, user authentication can be implemented on the end device. [0003] Take the terminal equipment that supports facial recognition payment in offline physical stores as an example. The terminal device can store the biometric data of the registered user received from the background server. When any user uses the terminal device to pay by swiping his face, the terminal device can collect the user's face image, and perform identity verification on the user based on the face image and locally stor...
