  • Tamper-evident form for securely carrying information
    Patent number: 6231082
    Abstract: A tamper-evident form for securely carrying information includes a scrambling pattern (4) which underlies the printed information such that the printed information cannot be read. Separation of the printed information and scrambling pattern, or other disabling of the scrambling pattern, is tamper-evident and renders the information readable. In preferred embodiments the information is printed on a lamina (6) which overlies the scrambling pattern (4). The information can be printed by conventional printers and no post-processing of the form is required to render the information secure.
