“…The improved encrypted version of proxy scheme called Fuzzy based Conditional Identity (FCI), in which exchange of medical data in a privacy-preserving where keys are extracted from user's biometric measures. The content of medical data transactions kept in privacy and consensus efficiency by using blockchain-based medical data storage platform [38]. The ring signature scheme is adopted the elliptic curve model to enhance a privacy medical data storage protocol in user's identity privacy and protection of medical data.…”

Data security and sharing remains nuisance among many applications like business data, medical data, banking data etc. In this research, block chain technology is built with encryption algorithm for high level data security in cloud storage. Medical data security seems critical aspect due to sensitivity of patient’s information. Unauthorized access of medical data creates major issue to patients. This article proposed block chain with hybrid encryption technique for securing medical data stored in block chain model at cloud storage. New Two fish encryption model is implemented based on RSA Multiple Precision Arithmetic (MPA). MPA works by using library concept. The objective of using this methodology is to enhance security performance with less execution time. Patient data is processed by encryption algorithm and stored at blockchain infrastructure using encrypted key. Access permission allows user to read or write the medical data attached in block chain framework. The performance of traditional cryptographic techniques is very less in providing security infrastructure. Proposed blockchain based Two fish encryption technique provides high security in less encryption and decryption time.

Unlike public chains, the Alliance Blockchain Hyperledger Fabric has a member management service mechanism that may provide data isolation security at the channel level. However, because this data isolation security technique synchronizes plaintext data inside the channel, data leakage is still a possibility. Furthermore, in some fine-grained privacy protection circumstances, channel-based data access restriction is ineffective. In order to solve the data privacy security problems in the above-mentioned consortium chain superledger, a blockchain data attribute encryption scheme based on ciphertext policy is proposed. Combining the original Fabric Certificate Authority module in the Hyperledger, the proposed scheme can realize the user-level fine-grained security access to control blockchain data while also realizing the secure distribution of user attribute keys in the blockchain data attribute encryption scheme based on the ciphertext policy scheme. The security analysis of the scheme shows that the scheme achieves the security goals of attribute-based encryption user attribute private key secure distribution and data privacy protection. The scope of this research is that this study confirms that the solution’s architecture achieves fine-grained access control of private data on the Hyperledger Blockchain network and also the security objectives of secure transmission of user characteristic secret keys and data privacy protection. The performance analysis part also shows that the proposed scheme has good usability.

The popularity of the Internet has given birth to e-commerce and promoted the development of logistics industry. Traditional logistics is frail in personal information confidentiality, and it is easy to leak privacy information in the process of logistics. This paper briefly introduced the channels of privacy information disclosure in the process of e-commerce logistics and the privacy information encryption system based on two-dimensional code. Then, the privacy protective effect of the system was tested on the laboratory server. The results showed that mobile terminals with different permissions only obtained some necessary logistics information within their respective permissions in the normal process; the mobile terminals distinguished two-dimensional codes that did not belong to express mails, and only meaningless error codes were obtained after the mobile terminal without permissions scanned the code in the abnormal process. In conclusion, the encryption technology of personal information based on two-dimensional code can effectively protect the privacy information in the process of logistics.
