Abstract
Systems and methods are disclosed that enable authentication based on a physical document. Specifically, a document authentication service is disclosed that utilizes characteristics of a physical document, such as an identification card already in a user's possession, to authenticate a user. In one embodiment, the characteristics of a document may be processed based at least in part on an expected wear of the document (e.g., from use by the user). Expected wear may be identified, for example, based on historical data gathered across a number of users of the document authentication service.
Claims22
A system for verifying the authenticity of a document, the system comprising:
- a data store including a plurality of security tokens, each of the plurality of security tokens corresponding to at least one of a plurality of physical documents enrolled with the system;
- a processor in communication with the data store and configured to:
- receive an authentication request including information regarding a presented document;
- generate a security token corresponding to the presented document based at least in part on processing the information regarding the presented document according to a token generation algorithm;
- compare the generated security token with a stored security token of the plurality of security tokens stored within the data store to determine a degree of difference between the generated security token and the stored security token;
- determine that the degree of difference between the generated security token and the stored security token satisfies an acceptability threshold, wherein the acceptability threshold is determined based at least in part on a period of time since the presented document was previously presented to the system and on an expected wear level associated with the presented document;
- and
- transmit an indication of successful authentication.
A computer-implemented method for verifying document authenticity, the method comprising:
- maintaining, within an authentication system, a plurality of security tokens corresponding to documents enrolled within the authentication system;
- receiving, at the authentication system, information regarding a document presented for authentication;
- generating, at the authentication system and based at least in part on the received information, a security token corresponding to the presented document;
- comparing, at the authentication system, the generated security token with at least one security token of the plurality of security tokens store to determine a degree of difference between the generated security token and the at least one security token;
- determining, at the authentication system, that the degree of different between the generated security token and the at least one security token satisfies an acceptability criterion, wherein the acceptability criterion is determined based at least in part on an expected wear level associated with the presented document;
- and
- transmitting from the authentication system an indication of successful authentication.
Non-transitory computer-readable storage media comprising computer-executable instructions to authenticate a document, wherein the computer-executable instructions, when executed by one or more processors corresponding to an authentication system, cause the processors to:
- generate a plurality of security tokens based at least in part on a plurality of documents presented for enrollment into the authentication system, wherein each of the plurality of security tokens corresponds to one of the plurality of documents;
- receive information regarding a document presented for authentication;
- generate, based at least in part on the received information, a security token corresponding to the presented document;
- compare the generated security token with at least one security token of the plurality of security tokens store to determine a degree of difference between the generated security token and the_at least one security token;
- determine that the degree of difference between the generated security token and the at least one security token satisfies an acceptability criterion, wherein the acceptability criterion is determined based at least in part on an expected wear level associated with the document;
- and
- transmit an indication of successful authentication.
The non-transitory computer-readable storage media of claim 16, wherein the expected wear level associated with the presented document is determined based at least in part on a substrate material of the presented document.
