Mrs. V. Deepa Priya, Meenakshi Sundaram, R. Arthy · 2023
This chapter provides a comprehensive review of the blockchain technology for image authentication and ownership verification. With the rise of digital imagery and the ease of sharing content online, ensuring the authenticity and ownership of images has become increasingly important. Traditional methods for image authentication and ownership verification often face challenges such as tampering, copyright infringement, and dispute resolution. Blockchain technology, with its decentralized and immutable nature, offers promising solutions to address these challenges. This work examines the various approaches, techniques, and frameworks proposed in the literature for blockchain-based image authentication and ownership verification. It explores the underlying principles of blockchain, its key features relevant to image security, and the benefits it brings to this domain. Furthermore, the paper presents a detailed analysis of the existing blockchain-based solutions, highlighting their strengths, limitations, and potential areas for improvement. Finally, it discusses emerging trends, open research challenges, and future directions in the field of blockchain-based image authentication and ownership verification.
