Blockchain-Based Approach for Proving the Source of Digital Media

The blockchain is an intelligent and cryptographically secure technology. Blockchain provides data integrity, security, and anonymity without any third-party enabling immutable database technology with a built-in trust mechanism. In this paper, we focused on utilizing blockchain technology for proving the origin of digital media by enhancing the functionality of an existing solution. This research improves the functionality of the existing solution by using perceptual hashing. Perceptual hashing ables to differentiate similar digital media and ensures the explicit relationship between the digital media and the content creator. Experimental results show that perceptual hashing gives better performance in the detection of image alteration and sensitive to small changes.
