Abstract
A first server receives from a device(s) an identifier, retrieves a reference credential(s) associated with the identifier(s), generates a reference token(s) using the reference credential(s) and a predetermined key(s) and sends to a second server the reference token(s) and a script(s) for requesting the user to provide a credential(s). The second server gets a device identifier(s) and sends to the device a request(s) by executing the script(s). The device gets a submitted credential(s), generates and sends to the second server a submitted token generated by using the submitted credential(s) and the predetermined key(s) stored by the device. The second server compares each of the submitted token(s) to the received reference token(s) and generates and sends to the first server a comparison and/or an authentication result(s). The invention also relates to corresponding device, first and second server and system.
