Secure Data Transfer Through Inter-Planetary File System (IPFS) and Block chain Embedded Smart Contract Using Multi-Level Authority and Encryption.

Abstract

The introduction of Smart contract-embedded blockchain systems incorporated with building Information model (BIM) in construction projects brought about the transformation of public and corporate management. The system, although it has contributed to infrastructure development, still faces vulnerabilities such as eavesdropping, data tampering, and possible attacks, requiring a secure communication channel. This research aims to develop a secure system for transferring data through the Inter-Planetary File System (IPFS), BIM and a blockchain-embedded smart contract. The system will use multi-level authority and encryption to ensure the confidentiality, integrity, and availability of the transferred data. The use of IPFS and a smart contract will allow for decentralized and distributed storage and transfer of data, while the use of multi-level authority and encryption will provide additional security measures to protect against eavesdropping, data tampering and theft. The resulting system has the potential to revolutionize the way data is transferred and stored, with applications in various industries and contexts.
