Abstract
The present invention is a secure data entry and visual authentication system that allows a user to securely input and communicate data, including passwords. The system includes a client subsystem (100), a server subsystem (200) and a communication subsystem (300). Server subsystem (200) generates a pseudorandomly arranged display image (250) including a plurality of icons associated with data, and transmits said display image to client subsystem (100) for display on a display device (104). A user consecutively selects at least one said icons corresponding to data desired to be input. Selected icon location information for those selected icons is communicated by client subsystem (100) to server subsystem (200), which then compares that selected icon location information to icon location information and associated data stored in memory (210) to ascertain the data input by the user.
