  • Patent number: 6523859
    Abstract: Confidential information is printed on an upper transparent laminate. A scrambling pattern is associated with a lower laminate. The upper surface of the lower laminate and the lower surface of the upper laminate are complementary in shape such that the upper laminate appears transparent, but alters to appear translucent when separated from the lower laminate. This provides a tamper-evident mechanism for indicating separation of the laminates.

  • Patent number: 6481753
    Abstract: Variable confidential information (12) is printed over scrambling pattern (14) which is formed of thermochromatic ink. Information (12) cannot be read due to the presence of the underlying scrambling pattern. The information becomes readable when heat is applied to the thermochromatic ink and the optical properties of the thermochromatic ink are altered.

  • 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.
