Abstract
A method for using optical media for identification purpose including the steps of exposing a portion of the optical media to a source of radiation; detecting an imperfection in the portion of the optical media; and, quantifying the imperfection to create a unique identifier. An apparatus for using an optical media for identification purposes, including a light source for exposing a portion of the optical media to a radiation; and, a receptor for receiving the radiation through the portion of the optical media, wherein the receptor measures a change in radiation that is received once the radiation has passed through the portion of the optical media.
Claims24
A method for using optical media for identification purposes, comprising:
- exposing a portion of the optical media to a source of radiation;
- detecting one or more imperfections in the portion of the optical media;
- quantifying the imperfections to create a unique identifier;
- and
- using the identifier as part of an authentication or security system to ensure that subsequent use of the optical media is properly authorized.
An apparatus for using an optical media for identification purposes, comprising:
- a light source for exposing a series of different locations of the optical media comprising one or more imperfections to a radiation;
- a receptor for receiving the radiation through the different locations of the optical media, wherein the receptor measures a change in radiation that is received once the radiation has passed through the different locations of the optical media comprising the imperfections;
- a computer system attached to the light source and to the receptor. the computer system configured to evaluate the change in the radiation received by the receptor and to determine from the evaluated change a unique identifier corresponding to the presence or lack of imperfections at the series of different locations;
- wherein the unique identifier is used to authenticate subsequent use of the optical media.
An apparatus for using optical media for identification purposes, comprising:
- a laser transmitter for directing a laser beam onto a series of different locations of an optical media;
- a laser receiver for receiving the laser beam after it has passed through the series of different locations of the optical media;
- and
- a processor configured to:
- evaluate the laser beam received by the laser receiver to detect a presence or lack of an imperfection at each location in the series of different locations,
- formulate a unique identifier for the optical media based on the detected presence or lack of an imperfection each location in the series of different locations, and
- record in a memory coupled to the processor the unique identifier to authenticate subsequent use of the optical media.
A method for uniquely identifying an optical media comprising the steps of:
- directing radiation to a first portion of the optical media;
- receiving the radiation once it has contacted the first portion of the optical media;
- evaluating a change in the radiation after it has contacted one or more imperfections existing in the first portion of the optical media;
- directing radiation to a second portion of the optical media;
- receiving the radiation once it has contacted the second portion of the optical media;
- evaluating a change in the radiation after it has contacted one or more imperfections existing in the second portion of the optical media;
- developing a unique identifier for the optical media based on the evaluated changes, wherein the unique identifier corresponds to the presence or lack of imperfections in the first and second portions;
- and
- storing and using the unique identifier to authenticate subsequent use of the optical media.
