In this paper, we introduce FileShare-a secure decentralized application framework for sharing files and data provenance. It overcomes the integrity and ownership issues in the existing solutions for file sharing and data provenance. In proposed framework, a Decentralized Application (dApp) on top of Ethereum is responsible for user registration and for provenance purposes. Ethereum smart contract is used to govern, manage, and provide traceability and visibility into the history of the shared content from its origin to the latest version. It employs IPFS, a distributed file system, as its data storage layer, avoiding the pitfalls of centralized storage solutions. The proposed framework utilizes an inbuilt editor to view and modify files. The files will be stored in an encrypted form on IPFS and can only be accessed in the FileShare text editor. Modify and share operations performed on shared files are recorded separately to the blockchain, ensuring high integrity, resiliency, and transparency.

KYC or Know-Your-Customer is an integral part of the onboarding process of a customer for a company. This process requires independent and tedious verification of a customer's identity documents by the businesses leading to wastage of resources. In this paper, we propose a solution where the submission and verification of a customer is done only once, and the results are shared with the businesses which require the information. The proposed system uses blockchain to record and manage the KYC requests and ensure transparency. The KYC data is verified using machine learning processes to ensure further efficiency in the process by reducing a significant amount of time spent on verifying the customers.
