Abstract
Based on the demand of developing a data encryption technique for the optical storage media, the present invention discloses a cryptography for data encryption based on a design of specific hardware conditions, so as to achieve the security requirements for the encrypted digital data stored in the optical storage media and the design requirements for the security issues on the optical storage media for software vendors in the current market.
Claims8
An optical storage media comprising a media content storage area and a code area, the code area comprising at least one damageable memory cell for providing a capability to record digital data;
- after a first data reading by a light source is completed, said memory cell is changed and thus the data is damaged, such that said light source cannot perform a second data reading;
- and said code area also comprises at least one general memory cell that remains readable after the first data reading by the light source.
An optical storage media comprising a media content storage area and a code area, the code area comprising at least a Read Once/Un-reversible reaction memory cell for providing a capability to record digital data;
- after a first data reading by a light source is completed, said memory cell is changed, and thus the data's logic level is reversed, such that at a second data reading, said light source can obtain a logic level that is reversed from said logic level of said first data reading;
- afterwards said memory cell permanently sustains said data with said reversed logic level and does not change anymore;
- and said code area also comprises at least one general memory cell that remains readable after the first data reading by the light source.
