System and method for network-based object authentication
A method is provided for determining whether an object is an authentic object to which an expected encoded image has been applied. The expected encoded image having been constructed by encoding an authentication image using a set of one or more encoding parameters. The method comprises receiving a digital image of at least a portion of the test object including a target area where the expected encoded image would be applied if the test object is an authentic object. The method further comprises determining the one or more encoding parameters and applying a digital decoding algorithm to the captured digital image to establish a decoding result. The decoding result may then be compared to object authentication criteria to establish an authentication result. In particular embodiments of the invention, the actions of receiving, determining, applying and comparing are carried out by an authentication server and the digital image is received from an inspection processor over a network.
1. A method for determining whether a test object is an authentic object to which an expected encoded image has been applied, the expected encoded image having been constructed by encoding an authentication image using a set of one or more encoding parameters so that if the expected encoded image is printed the authentication image is not discernible to a viewer without an optical decoding device having characteristics corresponding to at least one of the set of one or more encoding parameters, the method comprising:
Receiving a digital image of at least a portion of the test object including a target area where the expected encoded image, which was constructed so that if the expected encoded image is printed the authentication image is not discernible to a viewer without an optical decoding device having characteristics corresponding to at least one of the set of one or more encoding parameters, would be applied if the test object is an authentic object; determining the one or more encoding parameters; and applying a digital decoding algorithm to the captured digital image to establish a decoding result; wherein the actions of receiving, determining and applying are carried out by a decoding processor.
2. A method according to claim 1 wherein the digital image is received from an inspection processor over a network.
3. A method according to claim 2 wherein the network is the Internet.
4. A method according to claim 2 wherein the network is a telecommunications network.
5. A method according to claim 1 wherein the action of determining includes retrieving the one or more encoding parameters from an encoding information database.
6. A method according to claim 1 further comprising:
in an authentication processor, comparing the decoding result to object authentication criteria to establish an authentication result.
7. A method according to claim 6 further comprising:
transmitting the decoding result from the decoding processor to the authentication processor over a first network.
8. A method according to claim 7 wherein the digital image is received from an inspection processor over a second network with a request for authentication of the object.
9. A method according to claim 8 wherein the request for authentication includes at least one of the set consisting of object information, inspection processor information, requestor information, username and password information, and inspection location information.
10. A method according to claim 6 further comprising:
extracting decoded indicia from the decoding result.
11. A method according to claim 10 wherein the action of comparing the decoding result includes:
retrieving the authentication image from an encoding information database; and
comparing the decoded indicia to authentication image indicia.
12. A method according to claim 10 wherein the action of comparing includes:
comparing the decoded indicia to object-specific information.
13. A method according to claim 12 wherein the object-specific information is received with the digital image.
14. A method according to claim 12 wherein the object-specific information is retrieved from at least one of the set consisting of a database, a smart card, a magnetic strip, a bar code, a processor chip and a memory chip.
15. A method according to claim 12 wherein the object-specific information is extracted from the digital image.
16. A method according to claim 6 further comprising:
storing in an authentication database by a database server at least one of the set consisting of the decoding result and the authentication result.
17. A method according to claim 6 further comprising:
receiving by the database server from a monitoring processor a result request for the authentication result;
determining by the database server whether the result request is valid; and
in response to a determination that the result request is valid, transmitting the authentication result from the database server to the monitoring processor.
18. A method according to claim 17 wherein the result request is received from the monitoring processor and the authentication result is transmitted to the monitoring processor over a network.
19. A method according to claim 18 wherein the network is the Internet.
20. A method according to claim 17 wherein the authentication result is transmitted via electronic mail.
21. A method according to claim 17 wherein the authentication result is transmitted via text message over a telecommunications network.
22. A method according to claim 1 wherein the digital image is received via electronic mail.
23. A method according to claim 1 wherein the digital image is received via text message transmitted over a telecommunications network.
