Abstract: In a method for activating a palm-scanning service, a palm enrollment interface is displayed on a display of a terminal based on a pre-activation operation in association with a target account for the palm-scanning service and through execution of a target application by processing circuitry of the terminal. An image captured by a camera of the terminal is displayed in the palm enrollment interface. In the method, when palm information obtained from the image satisfies a palm enrollment condition, a server is notified to record pre-enrolled palm data for the target account based on the image. The server is configured to, when sample palm data for the target account collected separately from the image matches the pre-enrolled palm data, activate the palm-scanning service for the target account and record benchmark palm data for the target account according to the sample palm data.

Abstract: An iris feature acquisition policy of an iris identification device for a user is determined, the iris feature acquisition policy indicates a manner of acquiring an iris feature by using light spot imaging, and the iris feature acquisition policy includes one or more light spot imaging modes. One or more light spot iris images of the user are acquired based on the one or more light spot imaging modes and by using the iris identification device. Feature extraction is performed respectively on the one or more light spot iris images to obtain one or more light spot iris features. A light spot iris identification feature of the user under the iris feature acquisition policy is determined based on the one or more light spot iris features. The light spot iris identification feature is stored with identification information of the user into a database associated with the iris identification device.
