Abstract
A method and an apparatus of verifying a usability of a biological characteristic image are disclosed. The method includes: receiving a biological characteristic image uploaded by a terminal; verifying a digital watermark included in the biological characteristic image; and if verification is passed, determining that the biological characteristic image is usable. The technical solution of the present disclosure can ensure that a biological characteristic image generated in a device can only be used in that device, thus avoiding a security problem which may be caused by the theft and interception of a biological characteristic image of a user when storing or transmitting the image using a biological recognition technology.
