Abstract
A method, system, and display apparatus, for securely transmitting and displaying visual data, are disclosed. The method of securely transmitting and displaying the visual data includes encrypting the visual data, transporting encrypted visual data to a display apparatus, decrypting the encrypted visual data within the display apparatus, and displaying the visual data as a visual image. The step of decrypting the visual data includes maintaining an electronic version of the visual data within circuit elements that are substantially inaccessible. The system for securely transmitting and displaying the visual data includes an encryption apparatus, means for transporting the encrypted visual data, and the display apparatus. The display apparatus includes circuit elements that are substantially inaccessible. The circuit elements include a decryption circuit for decrypting the encrypted visual data, which forms the visual data within the display apparatus. The circuit elements also include a display circuit for displaying the visual data as a visual image. The circuit elements are configured such that an electronic version of the visual data is maintained within the circuit elements.
