Blockchain-enhanced proof of identity

A computer system comprising a processor, persistent storage and memory, which in combination are operable to implement a method of blockchain-enhanced proof of identity (POI) comprising:

• receiving identity information of a user in connection with a POI request;
• generating a first cryptographic hash using at least a portion of the identity information;
• storing the first cryptographic hash on a public blockchain in a first blockchain transaction;
• establishing a request identifier for the POI request based on an identifier for the first blockchain transaction;
• receiving a digital image that depicts the user together with a POI document, the digital image including the request identifier;
• responsive to successful validation of at least selected information in the digital image, creating a POI digital document comprising at least a portion of the digital image;
• generating a second cryptographic hash using at least a portion of the POI digital document;
• storing the second cryptographic hash on the public blockchain in a second blockchain transaction;
• and
• associating a shareable uniform resource locator (URL) with an identity proof related to the POI digital document, wherein the shareable URL translates to a page that shows at least a portion of the identity proof.

A computer-program product comprising a non-transitory computer-usable medium having computer-readable program code embodied therein, the computer-readable program code adapted to be executed to implement a method of blockchain-enhanced proof of identity (POI) comprising:

• receiving identity information of a user in connection with a POI request;
• generating a first cryptographic hash using at least a portion of the identity information;
• storing the first cryptographic hash on a public blockchain in a first blockchain transaction;
• establishing a request identifier for the POI request based on an identifier for the first blockchain transaction;
• receiving a digital image that depicts the user together with a POI document, the digital image including the request identifier;
• responsive to successful validation of at least selected information in the digital image, creating a POI digital document comprising at least a portion of the digital image;
• generating a second cryptographic hash using at least a portion of the POI digital document;
• storing the second cryptographic hash on the public blockchain in a second blockchain transaction;
• and
• associating a shareable uniform resource locator (URL) with an identity proof related to the POI digital document, wherein the shareable URL translates to a page that shows at least a portion of the identity proof.
