A Study on Secure Image Encryption Based on Blockchain

Abstract

Over recent decades, image data violations have created great difficulties, and image encryption has been an appealing field of research. Most people acknowledge this as a practical method of safe transmission. However, many studies have been conducted in various ways, and new and helpful algorithms have been proposed to improve the encryption systems of safe images. To increase this security, blockchain technology used by this technology eliminates or reduces the role of the third party by enabling two parties to transact with each other means that the Blockchain system can function in a peer-to-peer manner without a reliable third party required to ensure trust. This technology was first adopted to create digital cryptocurrencies, like Bitcoin and Ethereum. This technology has a range of characteristics, including transparency, anonymity, decentralization, immutability, and minting. With the advancement of Internet and communications, the exchange of sensitive data across multiple parties has become very easy. However, the problems associated with such communications are lack of integrity, confidentiality, and authenticity etc, caused by insecure channels. This paper aims to review recent key studies on secure image encryption based on blockchain in addition, explore how these two technologies can be combined to solve the problem of transport between unsafe channels where the blockchain network ensures that any tampering in the image will lead to the detection as any transaction in the blockchain tampers the associated hash. In addition, we comprehensively examine the key concepts and the most important metrics used to evaluate the model's performance and discussion of future work.
