Blockchain and IPFS-based Data Storage for VANET

CCTV cameras and black boxes in vehicles play an important role in road condition and accident management. CCTV laws require that data recorded by CCTV cameras be kept securely and only authorized people have access to it. CCTV footage and blackbox data are saved locally to the camera's microSD card, a separate hard drive, or the cloud. Security and data integrity are issues with both local and cloud storage. In this paper, we propose an IPFS and blockchain-based Decentralized Storage Application that stores files in a decentralized way. The proposed scheme is implemented using the private Ethereum blockchain, Smart Contacts, and IPFS.
