Abstract
A server accesses a user identifier associated with a first user device and a reference image as a first image set, to be displayed. The server sends to a second user device an image, as a second image set, to be displayed, and a user request to select an image within the first image set. The second user device displays the second image set and the user request. The user of the first user device selects at least one displayed first image, the selected first image matching an image visually selected within the displayed second image set, according to a rule known to the user and the server. The first user device sends to the server the first user device identifier accompanied with data relating to the selected first image. If the data relating to the selected first image matches the data relating to the first reference image the server authenticates the user.
