Validating Authenticity of Electronic Documents Shared via Computer Networks

A method performed by a server that verifies an authenticity of an electronic document shared via a computer network among computers, the method comprising:

• receiving, by the server, an electronic data comprising a current version of the electronic document and a metadata associated with the current version of the electronic document;
• generating, by the server, a current hash value by hashing only the metadata associated with the current version of the electronic document;
• recording the current hash value, generated by hashing of only the metadata associated with the current version of the electronic document, on a blockchain;
• retrieving, by the server, from the blockchain, a creational hash value, the creational hash value representing a metadata associated with an original version of the electronic document;
• comparing, by the server, the creational hash value to the current hash value;
• in response to the current hash value failing to match the creational hash value, determining, by the server, that the current version of the electronic document shared via the computer network among the computers is not an authentic copy of the original version of the electronic document;
• and
• generating, by the server, a fraud alert indicating the current version of the electronic document is inauthentic.

A system including a hardware processor and a memory device storing instructions that, when executed by the hardware processor, perform operations, the operations comprising:

• receiving, by the server, an electronic data comprising a current version of the electronic document and a metadata associated with the current version of the electronic document;
• generating, by the server, a current hash value by hashing only the metadata associated with the current version of the electronic document;
• recording the current hash value, generated by hashing of only the metadata associated with the current version of the electronic document, on a blockchain;
• retrieving, by the server, from the blockchain, a creational hash e, the creational hash value representing a metadata associated with an original version of the electronic document;
• comparing, by the server, the creational hash value to the current hash value;
• in response to the current hash value failing to match the creational hash value, determining, by the server, that the current version of the electronic document shared via the computer network among the computers is not an authentic copy of the original version of the electronic document;
• and
• generating, by the server, a fraud alert indicating the current version of the electronic document is inauthentic.
