1. An authenticator device of verifiable composition substance and informational content comprising:
- a sheet of medium having a machine-readable uniqueness characteristic sensible as translucency at specific locations of the sheet;
a format on said sheet of medium representative of critical statistical data; and
a machine-readable record on said sheet of medium decodable for comparison at least in part with each of said machine-readable uniqueness characteristic and said critical statistical data from a latter sensing.

Abstract
An authenticator device, e.g. card, of verifiable composition substance and informational content with a system of production and verification. Character uniqueness signals identifying the composition of the device are recorded on the card in an encrypted form combined with statistical data signals representative of information on the card. Testing the card involves freshly sensing the character uniqueness data and entering the statistical data. Such fresh data is then compared with the recorded values after decoding. Favorable comparisons manifest approval and enter the statistical data for processing.

9. An authenticator device for verifying authenticity comprising:
-
a sheet of medium having a varying random characteristic over an area of said sheet, said characteristic being inherent in the composition of said medium; machine-readable indicia on said sheet of medium, said indicia being decodable to specify the characteristic of said sheet at a specific area location; and print substance on said sheet positioned on at least a part of said specific area location to vary said random chartacteristic thereat.

10. A processor for a document or the like of a basic material substance having a uniqueness characteristic and bearing a machine-readable format representative of critical statistical data, said document further bearing a record relating to said uniqueness characteristic and said statistical data, said processor comprising:
-
means for sensing said record on said document to provide location signals indicative of at least one specific location on said document, prior characteristic signals indicative, at least in part, of the uniqueness characteristic of the basic material substance of said document at said specific location from a prior sensing, and prior data signals indicative, at least in part, of the critical statistical data on said document; means for sensing said uniqueness characteristic from said document to provide fresh characteristic signals representative, at least in part, of the uniqueness characteristic of the basic material substance of said document at said specific location; means for sensing said document format to provide fresh data signals representative, at least in part, of said critical statistical data; and means for comparing at least portions of said characteristic signals representative of said uniqueness characteristic and at least portions of said data signals representative of said critical statistical data to provide signals indicative of the authenticity of said document substance and content. - View Dependent Claims (11, 12, 13, 14, 15)
