| 1. An optically-readable storage media, comprising:
a substrate having encoded data stored thereon;
a reactive agent that, in response to a predetermined stimulus, interferes with the passage of light of a predetermined frequency
range,
wherein said reactive agent resides on the optically readable storage media directly in the optical path of a reading laser
of a reading device capable of reading the optically readable storage media; and
a second reactive agent, that in response to said predetermined stimulus, degrades the readability of the encoded data,
wherein said second reactive agent is in conformation with at least one of said encoded data, said substrate, or combination
thereof.
