password represented by diamond 44 in an input device such as a keyboard by way of example the user name may be a series of alphanumeric characters as is well known by way of example the password maybe a series of alphanumeric and special characters as is well known fig3 shows an example of the traditional username password login screen the username password is validated in box 46 if the authentication fails because of the username password entered a fake series of images that appear normal is displayed as shown at box 48 the user will be able to enter image identifier normally at diamond 58 however any authentication attempt fails as shown at reference numeral 68 if the username password pair is authenticated an image series will be generated and displayed at box 50 as shown on fig5 the cells of the series will display images from different categories the location of the categories in the series is randomized the specific image for each category is chosen from a database of images for that specific category each image will be overlaid with a unique randomly generated image key captcha techniques could be employed to obfuscate the image key so that it is not machine readable this would require a human to mediate the login and prevent automated brute force attacks on the authentication process an ancillary benefit of the present invention stems from the requirement of the user to view each of the visual images to determine which image is in the user.
