BLOCK CHAIN BASED EFFICIENT MANAGEMENT OF IOT SMART VIDEO SURVEILLANCE SYSTEM

Abstract

A management of surveillance of video process which is based on block chain technology has been proposed. The system which has been intended contains a network of block chain with internal nodes which are trusted. The distributed ledger of blockchain includes the metadata of the surveillance footage, thereby stopping the possibility of the data forgery. The architecture of proposed system saves and encrypts the footage, generates a license inside the block chain and exports the footage. Since the private database manages the decryption key for the footage in the block chain, it is not exposed by the internal nodes illegally. Also, the internal administrator can handle and export surveillance footage safely by decrypting the frames stored in the block chain and reconstructing the footage which can be later downloaded.
