摘要:
A method and system for providing copy-protected optical medium using transient optical state change security materials capable of changing optical state when exposed to a wavelength of about 630 nm to about 660 nm and software code to detect such change in optical state.

摘要:
A method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed. Light-sensitive compounds can be used to identify the product or product packaging. The product or product package may include visible or invisible ink containing a particular light-sensitive compound. One or more light-sensitive compounds and ink, if used, may be printed in one or more locations on the product or product packaging to produce an authentication mark to inhibit inadvertent or intentional removal of the mark, thereby rendering the mark tamper-resistant. The mark is sealed to isolate the mark from the environment. A device may be used to irradiate the mark and read light absorption or emission. A controller determines the authenticity of the mark by comparing the emitted or absorbed properties to a standard.
摘要:
A method and system for providing copy-protected optical medium using a substrate having information stored thereon in information pits and information lands, wherein the information lands comprise lands in two different planes.
摘要:
A method and apparatus for controlling access to a storage medium, such as an optically readable medium. Light sensitive or other materials that are adapted to change state and affect reading of a storage medium are used to control access to data that may be stored on optical medium and/or to control use of the medium.
