Abstract:
1. A method of authenticating user access to a restricted resource across a computer network, the method comprising: receiving user input identifier data, corresponding to a user, from a client device; determining whether the user is authorized, and if authorized, generating a random series of image identifiers in response to said user input identifier data; generating a set of user selectable images comprising a collection of images including a user-known image and a plurality of false images; receiving client device configuration data; determining a risk analysis score based on the client device configuration data; distorting each of the set of user selectable images if the risk analysis score is above a risk threshold; assigning the image identifiers to the user selectable images; sending the distorted user selectable images to the client device for display; receiving the image identifier assigned to the distorted image selected by the user; authenticating identity of said user from said selected image identifier; and allowing access to a restricted resource.
