BTDEC: Blockchain-Based Trible Data Elliptic Curve Cryptosystem with Fine-Grained Access Control for Personal Data

In an AI-driven era, data the board is reliant on security confirmation and open commerce. A standard data-sharing organization stage is important in the current data-sharing courses of action, and clients transmit their information to a cloud server for limitation and dispersion. Customers, on the other hand, would lose control of their data the instant it was sent off the server, making security and insurance a major worry. Even though data encryption and access control are regarded as cutting-edge innovations for storing individual data on cloud servers, they only go so far. Regardless, it continues to depend heavily on an external source of validity, the Cloud Service Provider (CSP). To tackle this challenge, they combined blockchain, 3DES ciphertext technology, ECC, and the Interplanetary File System (IPFS). This research focuses on BTDEC, a Blockchain-based Trible Data Elliptic Curve Crypto System for Personal Data. The data holder encrypts the sharing data and saves it on IPFS in this customer-driven way, boosting the decentralization of the arrangement. The standardized data area and unscrambling key will be coupled utilizing 3DES with ECC, and the data owner will disseminate his data-related information and send on keys to data customers using blockchain, according to the built-up confirmation method. The data may only be downloaded and interpreted by the data client whose credits fulfill the confirmation conditions. BTDEC enables the data owner to deny a particular data client at the individual dimension without affecting others, providing him fine-grained network access over his data. When obtaining data, the ciphertext phrase search is almost usually utilized to secure the data customer's security. They investigated BTDEC's security and recreated our technology on the EOS blockchain, proving the concept's validity. Meanwhile, they investigated the limitation and overhead and determined that BTDEC performed well.
