PROTECTION OF DOCUMENTS BY QR CODE-BASED STAMP

This abstract first appeared for US patent application 20250131114 titled 'PROTECTION OF DOCUMENTS BY QR CODE-BASED STAMP

Original Abstract Submitted

a system for protecting access to digital documents may include a blockchain network and a stamp generation node. the stamp generation node may receive a digital document and access parameters from a first user node. a unique identifier for the document may be generated and recorded on the blockchain with the access parameters. a qr code encoding a url for accessing the document may be generated and embedded in the document. a shortened url corresponding to the encoded url may be generated and transmitted to a second user node. when accessed, the shortened url may cause the stamp generation node to verify the access parameters on the blockchain and grant or deny access to the document based on the verification.
