Information storage and retrieval

摘要

Identifying information is stored or recorded on a recording element and camouflaged by recording the identifying information on a recording element through an information transformation medium such as a lenticular plate and then camouflaging the recorded information by recording the information on the same recording element through the information transformation medium, disposed at a different position than that used in recording the identifying information thereby concealing the identifying information recorded on the recording element. The concealed information thus storaged or recorded can be identified by observing the recording element through the same information transformation medium at the same position used in the initial recording of the identifying information.
