Abstract
Some implementations may provide a computer-implemented method for validating a digital document, the method including: receiving, at a computing device, the digital document comprising at least two digital watermarks, the digital document issued by a central entity; retrieving a first digital watermark from the digital document, the first digital watermark visually presented at a first time point; retrieving a second digital watermark from the digital document, the second digital watermark visually presented at a second time point, the second digital watermark being different from the first digital watermark and the second time point being different from the first time point; and reading the digital document based on the retrieved first and second digital watermarks.
Claims26
A computer-implemented method for reading a digital document, the method comprising:
- receiving, at a computing device, the digital identification document comprising at least two digital watermarks, the digital identification document issued by a central entity;
- retrieving a first digital watermark from the digital identification document, the first digital watermark visually presented at a first time point;
- retrieving a second digital watermark from the digital identification document such that a sequence of digital watermarks is retrieved, the sequence comprising the first digital watermark and the second digital watermark, the second digital watermark visually presented at a second time point, the second digital watermark being different from the first digital watermark, the second time point being different from the first time point by an amount shorter than a retina dwell time.
A mobile computing device for authenticating a person, the mobile computing device comprising at least one processor configured to perform operations comprising:
- receiving the digital identification document comprising at least two digital watermarks, the digital identification document issued by a central entity;
- retrieving a first digital watermark from the digital identification document, the first digital watermark visually presented at a first time point;
- retrieving a second digital watermark from the digital identification document such that a sequence of digital watermarks is retrieved, the sequence comprising the first digital watermark and the second digital watermark, the second digital watermark visually presented at a second time point, the second digital watermark being different from the first digital watermark, the second time point being different from the first time point by an amount shorter than a retina dwell time.
A non-transitory computer-readable medium, on which software instructions are stored, which instructions, when executed by a computer processor, cause the computer processor to perform the operations of:
- receiving, at a computing device, the digital identification document comprising at least two digital watermarks, the digital identification document issued by a central entity;
- retrieving a first digital watermark from the digital identification document, the first digital watermark visually presented at a first time point;
- retrieving a second digital watermark from the digital identification document such that a sequence of digital watermarks is retrieved, the sequence comprising the first digital watermark and the second digital watermark, the second digital watermark visually presented at a second time point, the second digital watermark being different from the first digital watermark, the second time point being different from the first time point by an amount shorter than a retina dwell time.
