Security And Privacy Issues Of Block-Chain Technology

[Full Text]



Amal Hassan M.Alsuhaimi , Sabah M.Alzahrani



Block-chain, Security, Privacy, Group signature, Zero-knowledge.



Block-chain is getting popular and it is one of the most common topics that can be considered. it has also changed the lifestyles of many people in certain fields, because of the impact on businesses and combines. Blockchain ensures more reliable and appropriate resources and it is very crucial to keep in mind that the security and privacy have some obstacles as any technology in this fields. The spectrum of blockchain applications is very extended into different areas in banking, health, automotive, the Internet of Things (IoT) etc. Many studies concentrate on using the block-chain data model in different implementations. In this paper we try to describe block-chain technology by discussing its model of a data protection and privacy perspective with different consensus algorithms, as well as issues and opportunities in block-chains.
