Abstract
A method for secure authentication is provided which includes having a user who wishes to gain access to a computer or computer network select from among a plurality of randomly displayed images, having different background colors, the correct image and background color which correspond to the user's computer account. In one advantageous form, in addition to selecting the correct image, the user must first enter a username and password. In an alternative form, if a user is seeking access to a computer network by using a preapproved access point or computer having an approved IP address, a user is allowed to gain access to the computer network without being prompted to select a correct image.
