Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obtaining image data of an identification (ID) document and identifying a pattern of the ID document based on analysis of the image data against a predefined patterns for a particular type of document. An identifier engine of the system computes a frequency metric that defines how often the pattern reoccurs at the ID document and generates a unique identifier for the ID document based on the computed frequency metric. The unique identifier is stored at a digital fingerprint database of the system as a digital fingerprint for the ID document.
Claims20
A computer-implemented method, comprising:
- obtaining image data of an identification (ID) document;
- identifying a pattern of the ID document based on analysis of the image data;
- computing a frequency metric corresponding to a reoccurring attribute of the pattern at the ID document;
- generating a unique identifier for the ID document based on the frequency metric by mapping the frequency metric to the identifier;
- and
- storing the unique identifier as a digital fingerprint for the ID document.
A computer-implemented method, comprising:
- obtaining image data that provides a graphical representation of a first document;
- identifying multiple patterns at the first document based on analysis of the image data against predefined patterns for different types of documents;
- for each identified pattern of a particular pattern type:
- computing a respective frequency metric corresponding to a reoccurrence of the pattern at the first document;
- in response to computing the respective frequency metric, generating a unique identifier for the first document using the respective frequency metric for each of identified patterns of the particular pattern type by mapping the frequency metrics to the identifier;
- and
- storing the unique identifier at a digital fingerprint database.
A system, comprising:
- one or more processing devices;
- and
- one or more non-transitory machine-readable storage devices storing instructions that are executable by the one or more processing devices to cause performance of operations comprising:
- obtaining image data that provides a graphical representation of a first document;
- identifying multiple patterns at the first document based on analysis of the image data against predefined patterns for different types of documents;
- for each identified pattern of a particular pattern type:
- computing a respective frequency metric corresponding to a reoccurrence of the pattern at the first document;
- in response to computing the respective frequency metric, generating a unique identifier for the first document using the respective frequency metric for each of identified patterns of the particular pattern type by mapping the frequency metrics to the identifier;
- and
- storing the unique identifier at a digital fingerprint database.
One or more non-transitory machine-readable storage devices storing instructions that are executable by one or more processing devices to cause performance of operations comprising:
- obtaining image data that provides a graphical representation of a first document;
- identifying multiple patterns at the first document based on analysis of the image data against predefined patterns for different types of documents;
- for each identified pattern of a particular pattern type:
- computing a respective frequency metric corresponding to a reoccurrence of the pattern at the first document;
- in response to computing the respective frequency metric, generating a unique identifier for the first document using the respective frequency metric for each of identified patterns of the particular pattern type by mapping the frequency metrics to the identifier;
- and
- storing the unique identifier at a digital fingerprint database.
