Image verification by an electronic device

摘要

A method for verifying an image by a first electronic device, the method comprising the first electronic device: sending a request for an image to a second electronic device, wherein the second electronic device is remote from the first electronic device and, optionally, a server; receiving an image and a certificate from the second electronic device, wherein the certificate comprises a protected checksum of at least the image; generating a checksum in dependence on at least the received image; performing a comparison in dependence on said generated checksum and the protected checksum received in the certificate; and verifying the received image in dependence upon the comparison. Advantageously, the first electronic device is able to verify each received image and to prevent the display of any received images that are not authenticated. Applications include the display of card images.
