Abstract
In a decentralized network every user makes use of personal identity details at different places for various services and these details are shared with third-parties without their consent and stored at an unknown location. Organizations like government, banks and social platforms are considered to be the weakest area in the current identity management system as they are vulnerable which in turn leads to compromising billions of user identity data. Block chain based User Identity Management is a solution which provides a decentralized environment that manages the user identity data and their related Know-Your-Customer documents in a distributed ledger. All the transactions of the network are stored in the block, which is a type of a data structure and these blocks are validated using the powerful consensus algorithms and linked to form a block chain. Smart contracts will act as an interface between the client and the block chain network. User’s information cannot be provided to any third party vendors without the explicit consent of the user. This paper proposes a framework for User Identity Management using Block chain technology in a decentralized network. The proposed framework ensures a high level privacy and security for the personal identity details and the documents. In addition to that the performance analysis of the framework is presented in terms of Transaction immutability, Mining Resource, Memory utilization and Difficulty Variation. The results of the analysis proves that the proposed framework performs better in terms of all these factors.

Summary
Today in this digitalization era users can able to access any type of digital services from anywhere. Since all data are stored in a single location there is a lot of possibility for security compromise using the variety of security attacks which may lead to lot of danger to the individual person, since the individual may use the same identity to utilize different type of services. Many of the organization use some Third party service providers to handle the personal identity data and kyc documents. The three main characteristics[12] which make the block chain as a unique strategy to handle the current digital technologies are a)Decentralization where there is no centralized entity or any third party sources to store the data or performing any network control activities. Consensus algorithms ensure that only a valid transaction or block is added to a block chain These algorithms use some strategy for finding a specific value called Nonce.
