Abstract
A document liveness detection method comprising using a hardware processor for prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change; and image-processing the image sequence to yield an output indication of whether or not the image sequence was generated by capturing a live or physical document; and providing the output indication to at least one computerized system or human.
Claims17
A document liveness detection method comprising using a hardware processor for:
- prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change;
- and
- image-processing the image sequence including generating an output indication of whether or not the image sequence was generated by capturing a live or physical document;
- and
- providing the output indication to at least one computerized system or human,
- wherein said image processing comprises estimating a thickness of the physical document and comparing the thickness as estimated to a known thickness value of the physical document,
- wherein plural categories of physical documents are received,
- wherein the known thickness value differs between said categories, and
- wherein said image processing comprises receiving metadata, provided by the end-user, indicating that the physical document in the image sequence belongs to a category C and comparing the thickness as estimated to a known thickness value of documents in category C.
A computer program product, comprising a non-transitory tangible computer readable medium having computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a document liveness detection method comprising using a hardware processor for:
- prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change;
- and
- image-processing the image sequence including generating an output indication of whether or not the image sequence was generated by capturing a live or physical document;
- and
- providing the output indication to at least one computerized system or human,
- wherein said image processing comprises estimating a thickness of the physical document and comparing the thickness as estimated to a known thickness value of the physical document,
- wherein plural categories of physical documents are received,
- wherein the known thickness value differs between said categories,
- wherein said image processing comprises receiving metadata, provided by the end-user, indicating that the physical document in the image sequence belongs to a category C and comparing the thickness as estimated to a known thickness value of documents in category C.
A system comprising at least one hardware processor configured to carry out operations comprising:
- prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change;
- and
- image-processing the image sequence including generating an output indication of whether or not the image sequence was generated by capturing a live or physical document;
- and
- providing the output indication to at least one computerized system or human,
- wherein said image processing comprises estimating a thickness of the physical document and comparing the thickness as estimated to a known thickness value of the physical document,
- wherein plural categories of physical documents are received,
- wherein the known thickness value differs between said categories, and
- wherein said image processing comprises receiving metadata, provided by the end-user, indicating that the physical document in the image sequence belongs to a category C and comparing the thickness as estimated to a known thickness value of documents in category C.
