Abstract
An authentication process controls access from a client terminal 2 to a remote server 3 via an unsecure network, by transmitting a challenge 63 from the server to the client in the form of a matrix barcode into which is embedded a sequence of images embedded in it selected (step 61) from a predetermined set of images stored on the server. The user responds to the challenge (e.g by sorting the images into groups, or order, according to a rule which is a shared secret (step 64) and generates a response in the form of a code (step 67) generated dynamically by convolving the user response 64 with a random PIN string (65) extracted from the matrix barcode, and data intrinsic to the user terminal, using a predetermined dynamically generated encryption algorithm for transmission to the server (step 68) for verification (69).
