Applications and Challenges of Blockchain Technology in Image Processing: A Comparative Review

With the increase in internet usage, blockchain technology has risen in popularity in recent years as one of the hottest technologies. It uses decentralized architecture with distributed database and provides cryptography thus giving integrity of data without using a third party. It is used to increase security and privacy in various applications. There is an expanding variety of applications not only in finance but also important to image processing, even though they were initially developed for and most frequently used with cryptocurrencies. This paper provides examination of blockchain technology in image processing. It also discusses potential implementation difficulties as well as the ideas that underlie the technology and applications pertinent to image processing. This paper intensively analyzes the existing research work, provides issues in blockchain for image processing, and provides refined observation of each problem so that future research can be conducted efficiently.
