摘要:
A storage case of storing optical digital data storage media, the case including a cover with a defined area therein that permits transmission of certain energy to the medium stored therein while the area of the cover outside of the defined area does not.
摘要:
Formulations useful in the manufacture of anti-theft and copy-protected digital recording media, in an embodiment comprising a state change material in a hardcoat polymer.
摘要:
Light sensitive materials applied in shipping materials, including security seals and tear tape, for authentication, discrimination and recognition of items.
摘要:
A system for selectively enabling or disabling an optical device. In an illustrative embodiment, the system implements an optical-device theft-prevention system. The theft-prevention system includes a material that is selectively positioned on, in, or relative to the optical device so that the transparency of the material affects a desired operation of the optical device. An energy beam is selectively employed to enable or disable the optical device by affecting the transparency of the material. In a specific embodiment, the fist material includes a dye, such as an energy-sensitive dye. The optical device includes an optical disc, such as Compact Disc (CD) or Digital Video Disc (DVD). The energy-sensitive dye is disposed over an entire readable surface of the optical device.
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.
摘要:
Embodiments of the invention relate to the association of a non-guessable, unique ID with a user and the automatic or electronic referral of user ID to a medical service provider, without revealing private medical information. After the assignment of a unique ID to a User, the ID may then provide authentication by a certified health care source. In some embodiments, the delivery of a unique ID to a User can act as a token that can provide authentication for data entering a secure transmission system for medical referrals and tracking. In some embodiments, an electronic system compensates various parties by tracking activities associated with a unique user ID number without revealing any private medical information of a user also associated with the ID.
摘要:
A piracy protection digital recording medium comprising a polymeric layer incorporating an optical state change material in conjunction with a cationic photoinitiator.
摘要:
A piracy protection digital recording medium comprising an optical recording medium coated with a polymeric film containing authentication state change material therein, the authentication state change material being readable by a digital reader of such optical recording medium.
摘要:
An optical medium piracy method and system employing a ultraviolet-sensitive state-change material capable of changing state upon activation with a wavelength of ultraviolet between 253+/−25 nm to 365+/−25 nm, the state-change material in association with digital data indicia, wherein when the state-change material is activated to change state by the ultraviolet radiation, the optical medium moves from an unreadable to a readable condition, or from a less readable to more readable condition.
摘要:
A method and apparatus for preventing copying of data from optical disks. A locus on optical disk is initially read to produce a signal and is then re-read by a reader to produce a second signal. The signal detected upon re-reading is different from the signal that is detected upon initial sampling. A method and apparatus for controlling access to an optical disk, such as an optically readable disk. Light sensitive or other materials that are adapted to change state and affect reading of an optical disk are used to control access to data that may be stored on optical disk and/or to control use of the optical disk.
