| dc.description.abstractEN | Customer credentials privacy has always been serious issues in the centralized platform such as cloud storage etc. credentials verification and dealing in these specific centralized ways could lead to the privacy breaches. Self-sovereign identity system using blockchain smart contract could ensure user privacy and better data control to do the basic operations. Casper has been discussed to address the privacy issues while using SSI and blockchain systems. The credentials and identity details are stored in the digital wallet through encryption which are hard to bypass by the cybercriminals to sabotage privacy. Casper employs Zero-Knowledge Proof mechanisms to verify the identity information from the credential proofs. In user data bank control over data is what needed the most which could by the implementation of SSI while using blockchain. | el |
