Claim Text:
1. A self-authenticatable object, comprising: (a) a manufactured sealing tape product having a top surface and an adhesive lower surface, and at least one tamper evident feature to indicate a removal of the sealing tape from a surface to which it was adhered, or tampering with the sealing tape, produced by a manufacturing process having limited precision with respect to a state of a set of stable, optically readable, non-deterministic characteristics of features beneath the top surface and visible from outside of the top surface, the state being defined as a set of information determined based on a measurement of a plurality of non-deterministic characteristics to assure that the defined state of the set of non-deterministic characteristics is unique with respect to other manufactured products; (b) a fiducial guidance pattern printed on the sealing tape configured to define a series of authentication regions of the sealing tape; and (c) a set of automatically readable, recorded messages periodically printed on the sealing tape in a deterministic printing process after the state of the set of stable, optically readable, non-deterministic characteristics is established, each being associated with a respective defined authentication region and representing self-authenticating cryptographically protected irreversible compressed information defined selectively in dependence on a subset of the set of stable, optically readable, non-deterministic characteristics to be authenticated which are associated with a respective recorded message, determined at a time when authenticity is assured and after the manufacturing process is complete, wherein the features and the recorded messages are disposed to be readable in a single image, and wherein analysis of a state of the defined subset of the set of stable, optically readable, non-deterministic characteristics within a respective authentication region, at a time when authenticity is to be ascertained, with respect to the respective recorded message associated with that respective authentication region, permits authentication of the a portion of the sealing tape associated with a respective recorded message with respect to other portions of sealing tape, without revealing the information defining the subset of the set of stable, optically readable, non-deterministic characteristics to be authenticated, determined at a time when authenticity is assured.
