What is Human Identification

In the present world, we need a secured human identification system to identify humans. These kinds of systems will help forensics and the healthcare sector. But with the rapid development of technology there might have a huge security problem with these kinds of security systems. So, we also need more highly secured technology to implement this secured system. Because of this concern the authors move with the blockchain as the main technology area for this application. Also, the authors chose to use DNA or genome to identify humans as the unique key. Applying DNA binary sequence to the blockchain will provide multiple problems, which are finding and suitable algorithms. So, in this review, the authors are providing a systematic literature review (SLR) by focusing on multiple factors which are blockchain and the DNA using standard eight databases. From these reviews, the authors found the 73 total research publications, and after reading the title and the abstraction the authors selected the most relevant 10 research papers for this research domain. This paper is discusses the most suitable technology combinations and future works.
