Abstract

Exemplary methodology, procedure, system, method and computer-accessible medium can be provided for authenticating a non-digital medium of a physical object, by receiving at least one image of video of at least one marked or unmarked region, and comparing the first microscopic image or video of at least one marked or unmarked region with at least one second microscopic image or video relating to the non-digital medium to determine if a similarity between the first and second microscopic images or videos matches or exceeds a predetermined amount.

First claim

What is claimed is:

1. A non-transitory computer-accessible medium having stored thereon computer-executable instructions for authenticating at least one physical object, wherein, when a computer hardware arrangement executes the instructions, the computer arrangement is configured to perform procedures comprising:
(a) determining, a priori, settings for an imaging device;
(b) receiving at least one of at least one first microscopic image or at least one first microscopic video of the at least one physical object based on a partially coherent light source from the imaging device;
(c) determining at least one first set of keypoint descriptors related to at least one first microscopic texture of the at least one physical object based on the at least one of the at least one first microscopic image or the at least one first microscopic video using a fixed scale and a fixed orientation version of a scale invariant feature transform (SIFT) procedure;
(d) receiving at least one of at least one second microscopic image or at least one second microscopic video of the at least one physical object based on the partially coherent light source;
(e) determining at least one second set of keypoint descriptors related to at least one second microscopic texture of the at least one physical object based on the at least one of the at least one second microscopic image or the at least one second microscopic video using the fixed scale and the fixed orientation version of the SIFT procedure;
(f) comparing at least two descriptors of the first set of keypoint descriptors with at least two descriptors of the second set of keypoint descriptors to determine matching descriptors;
(g) obtaining a first slope of at least two of the matching descriptors, and a second slope of at least other two of the matching descriptors;
(h) determining a set of differences of slopes comprising the first slope and the second slope and between other slopes; and
(i) authenticating the at least one physical object based on a minimum percentage of the set of differences of the slopes.

2. The computer-accessible medium of claim 1 , wherein the physical object includes a paper.

3. The computer-accessible medium of claim 1 , wherein the computer arrangement is stored on at least one of a handheld computing device, a cellphone or a stationary computing device, and at least one microscope arrangement is attached to the handheld computing device, the cellphone or the stationary computing device.

4. The computer-accessible medium of claim 1 , wherein the at least one first microscopic texture is from at least one of a region in the at least one physical object without a mark or at least one content of the at least one physical object.

5. The computer-accessible medium of claim 4 , wherein the at least one content includes information related to at least one of at least one user or at least one object identity.

6. The computer-accessible medium of claim 1 , wherein the at least one first microscopic texture is extracted from at least one region near at least one landmark, and wherein the at least one landmark is at least one content of the at least one physical object.

7. The computer-accessible medium of claim 1 , wherein at least one of the at least one first microscopic texture or the at least one second microscopic texture includes at least one texture speckle pattern.

8. The computer-accessible medium of claim 1 , wherein the at least one first set of keypoint descriptors and the at least one second set of keypoint descriptors include at least one of a local descriptor or a global descriptor.

9. The computer-accessible medium of claim 1 , wherein the computer arrangement is further configured to (i) convert the at least one first microscopic texture, using an object invariant procedure, into a first low dimensional representation, (ii) convert the at least one second microscopic texture, using the object invariant procedure, into a second low dimensional representation, and (iii) perform a further comparison procedure by determining if a particular metric distance between the first low dimensional representation and the second low dimensional representation is within a predetermined amount, wherein the predetermined amount is determined using a mathematical function.

10. The computer-accessible medium of claim 1 , wherein the computer arrangement is further configured to (i) convert the at least one first microscopic texture into first data using an object invariant, scale and rotation invariant gradient histogram feature descriptor procedure, (ii) convert the at least one second microscopic texture into second data, using the object invariant, scale and rotation invariant gradient histogram feature descriptor procedure, and (iii) determine the similarity measure by determining if a certain metric distance between the first data and the second data is within a predetermined amount, wherein the predetermined amount is determined using a mathematical function.

11. The computer-accessible medium of claim 1 , wherein the partially coherent light source is at least one of a visible, an infra-red, an ultra-violet or a combination thereof, which is configured to provide a multispectral electromagnetic radiation.

12. The computer-accessible medium of claim 1 , wherein the at least one physical object is at least one of aged, tampered, crumpled or soaked.

13. The computer-accessible medium of claim 9 , wherein the computer arrangement is further configured to cause the first low dimensional representation to be printed on the at least one physical object.

14. The computer-accessible medium of claim 1 , wherein computer arrangement is further configured to authenticate the at least one physical object using at least one of a secret key cryptography procedure or a public key cryptography procedure.

15. The computer-accessible medium of claim 1 , wherein the computer arrangement is further configured to store the at least one first microscopic texture and the at least one descriptor as data in an online repository.

16. The computer-accessible medium of claim 1 , wherein the computer arrangement is further configured to perform the authentication procedure by comparing a first portion of the at least one first microscopic texture to a second portion of the at least one second microscopic texture, wherein the first portion is less than an entirety of the at least one first microscopic texture and the second portion is less than the entirety of the at least one second microscopic texture.

17. The computer-accessible medium of claim 1 , wherein (i) the at least one physical object is a particular physical object, and (ii) the at least one first microscopic texture is a unique identification of only the particular physical object.

18. A method for authenticating at least one physical object comprising:
(a) determining, a priori, settings for an imaging device;
(b) receiving at least one of at least one first microscopic image or at least one first microscopic video of the at least one physical object based on a partially coherent light source from the imaging device;
(c) determining at least one first set of keypoint descriptors related to at least one first microscopic texture of the at least one physical object based on the at least one of the at least one first microscopic image or the at least one first microscopic video using a fixed scale and a fixed orientation version of a scale invariant feature transform (SIFT) procedure;
(d) receiving at least one of at least one second microscopic image or at least one second micro
