Abstract
Abstract A method is disclosed for printing an authenticatable image having an embedded image into a receiver having a discernible physical characteristic, such that the printed image can be used to authenticate the receiver includes scanning the receiver to produce information related to the discernible physical characteristic of the receiver, and providing a carrier which includes information related to the scanned receiver discernible physical characteristic. The method also includes combining the carrier with an input image to form the authenticatable image having the embedded image, and printing the authenticatable image having the embedded image onto the receiver.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
A method for printing an authenticatable image having an
embedded image into a receiver having a discernible physical characteristic, such
that the printed image can be used to authenticate the receiver, comprising the
steps of: a) scanning the receiver to produce information related to the
discernible physical characteristic of the receiver; b) providing a carrier, which includes information, related to
the scanned receiver discernible physical characteristic; c) combining the carrier with an input image to form the
authenticatable image having the embedded image; and d) printing the authenticatable image having the embedded
image onto the receiver.
Claim 2
Dependent Claim
33 words
The method of claim 1 wherein the discernible physical
characteristic of the receive is the fibrous content of the receiver and the carrier is
produced from scanning a predetermined region of the receiver.
Claim 3
Dependent Claim
52 words
The method of claim 3 wherein the carrier producing step
includes: i) transforming the carrier to a Frequency domain to
form a transformed carrier; ii) shaping the transformed carrier's spectrum to cancel
the MTF of the print process or to facilitate the human visual system; and iii) inverse transforming the transformed carrier.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein the carrier producing step
further includes encrypting the carrier signal by rearranging portions of the carrier
in accordance with a key.
Claim 5
Independent Claim
75 words
A method of authenticating a receiver having an
authenticatable image having an embedded image having information related to
the discernible physical characteristic of the receiver, comprising the steps of: a) scanning the authenticatable image on the receiver to
produce information related to the discernible physical characteristic of the
receiver; and b) comparing the scanned discernible physical characteristic
information with the discernible physical characteristic of an authentic receiver to
determine the authenticity of the authenticatable image.
Claim 6
Dependent Claim
30 words
The method of claim 5 wherein the discernible physical
characteristic of an authenticated receiver is determined by scanning a portion of
the receiver on which the authenticatable image is formed.
Claim 7
Dependent Claim
33 words
The method of claim 5 wherein the discernible physical
characteristic of the receiver is the fibrous content of the receiver and the carrier is
produced from scanning a predetermined region of the receiver.
Claim 8
Dependent Claim
49 words
An authenticatable digital image, comprising: a) an input image which will be visible to a viewer when the
authenticatable image is printed; and b) an embedded image in the input image and having a
discernible physical characteristic related to the receiver into which the
authenticatable image will be provided.
Claim 9
Dependent Claim
33 words
The method of claim 1 wherein the discernible physical
characteristic of the receive is the fibrous content of the receiver and the carrier is
produced from scanning a predetermined region of the receiver.
