US Patent 11960579 Smart glass and blockchain digital signature implementation

Aspects of the disclosure relate to using smart glass and distributed ledger technology to provide secure authentication for digitally hand signing documents. Smart glasses worn by a customer may be activated via an application on a mobile device. The smart glasses may then scan the document and a biometric feature of the customer. The captured biometric feature and document content may be stored on a distributed ledger system. Based on the information stored on the distributed ledger, a unique binary code may be generated. The binary code may be converted into an image and shared with the mobile application. The image may then be embedded into the document as a digital hand signature. The document and the embedded image may be submitted to nodes of the distributed ledger for authentication of the digital hand signature.
