Blockchain driven embedded video and digital signatures on signed documents

Abstract

Systems, devices and methods are provided for blockchain driven embedded video and digital signatures on signed documents. The present disclosure includes providing a video conference initiated with the process of signing a document. The video conference and the signing process and the video are recorded. The recorded video captures all conversations, understanding and the final signing by participants. Both the signature and the recorded signing event in video conference are stored with a hash value as a blockchain.

What is claimed is: 
     
         1 . A computer-implemented method for a blockchain, the method comprising:
 generating a hash value for a smart contract and a file containing digital contents;   storing the file, the smart contract and the hash value; and   updating a blockchain including the file, the smart contract and the hash value.   
     
     
         2 . The computer-implemented method of  claim 1  further comprises:
 receiving an updated copy of the blockchain; 
 verifying a hash value in the updated copy of the blockchain; and 
 if the hash value does not match the stored hash value, determine that the updated copy of the blockchain contains at least one of a tempered copy of the smart contract or a tampered digital contents thereby invalidating a contract integrity. 
 
     
     
         3 . The computer-implemented method of  claim 1 , wherein the file comprises video content. 
     
     
         4 . The computer-implemented method of  claim 1 , wherein the file comprises audio content.
