Abstract
Disclosed is a method for authenticating a user by user identifier and associated graphical password. The graphical password includes a sequence of several images belonging to a group of images. The user provides a user identifier to an application, and graphically selects a sequence of several images in this group of images, the image order being randomly displayed by the application with each authentication of the user. The application identifies the position of each selected image in the sequence, establishes the correspondence between the sequence of the positions and the sequence of the identifiers of the selected images, compares the sequence of the selected images identifiers with the registered sequence, the application being the only entity able to establish this correspondence and/or the application being the only entity able to make this comparison, and authenticates the user if the comparison is positive but refuses authentication for negative comparison.
