Thanks Plank , these paragraphs show absolutely no prior art for Micro signet !

Some techniques offer data access security through the use of data related to physical characteristics of the storage media. These systems rely on precise measurement of solid state media process characteristics. Examples of these include variations in the remnant charge of EEPROM's, or variations in row/column addressing circuits. These and other characteristics have been used for authentication when the memory is presented, and the authenticating characteristics are measured. Such techniques are described in detail in Fernandez (U.S. Pat. No. 5,644,636).
The critical issue which cannot be addressed by the prior art are applications where data security is not simply shifted to attacks on the reader mechanisms and where data must not be duplicated or separated even by trusted and/or authorized users.
