Blockchain for data sharing
Cognizant has teamed up with 14 Indian insurance firms on the development of a blockchain solution for cross-company data sharing. The IT multinational said in a statement on Monday that the platform was designed to allow firms to securely share data with lower risk of data breaches and fraud, while offering greater efficiency, better record-keeping and faster turnaround than with traditional methods. Anand Pejawar, president of operations at SBI Life, said that the decentralized and immutable nature of blockchains, which provide the ability to combat document tampering and false billing, are opening up new models for insurers. By storing data on blockchain, the statement adds, insurers will see benefits including reduced operating costs and duplication of processes. Arun Baid, global delivery head for insurance at Cognizant, commented, "As a shared source of truth, blockchain opens numerous possibilities for insurers to collaborate more effectively and transparently, make better informed decisions, and create greater trust and accountability, while disintermediating data aggregators.

A blockchain-assisted framework for secure and reliable data sharing in distributed systems
Predictive maintenance customers of industrial equipment producer Robert Bosch will soon be able to leverage blockchain to exchange data with peers without triggering privacy controls. Bosch and Fetch started their collaboration in and completed an initial pilot earlier this year. Predictive maintenance enables artificial intelligence AI to learn from data produced from industrial devices and predict the likelihood of critical failures. While it has potential to reduce machinery downtime, Bosch and Fetch believe individual plants produce insufficient data to train the predictive AI from. By implementing blockchain, Bosch expects clients to opt into sharing anonymized data with one another.
A Blockchain Platform for User Data Sharing Ensuring User Control and Incentives
Meanwhile, the health-related mobile apps and devices also generate a large amount of medical data, which is critical for promoting disease research and diagnosis. However, medical data is too sensitive to share, which is also a common issue for IoT Internet of Things data. The traditional centralized cloud-based medical data sharing schemes have to rely on a single trusted third party. Therefore, the schemes suffer from single-point failure and lack of privacy protection and access control for the data. Blockchain is an emerging technique to provide an approach for managing data in a decentralized manner.
5 Blockchain Platforms for Better Use of Data
Special Issue: Computer Architecture and Systems. With the development of network technology and cloud computing, data sharing is becoming increasingly popular, and many scholars have conducted in-depth research to promote its flourish. As the scale of data sharing expands, its privacy protection has become a hot issue in research. Moreover, in data sharing, the data is usually maintained in multiple parties, which brings new challenges to protect the privacy of these multi-party data. In this paper, we propose a trusted data sharing scheme using blockchain. We use blockchain to prevent the shared data from being tampered with, and use the Paillier cryptosystem to realize the confidentiality of the shared data. In the proposed scheme, the shared data can be traded, and the transaction information is protected by using the p, t -threshold Paillier cryptosystem. We conduct experiments in cloud storage scenarios and the experimental results demonstrate the efficiency and effectiveness of the proposed scheme.

Data sharing is very common in the era of big data and artificial intelligence as the convergence of data is the most prerequisite section of big data and machine intelligence happens based on high volume data feed. Blockchain is a new emerging technology, which holds vast possibilities and benefits to improve traceability and accountability of its stored data. It has significant advantages in unlocking the full potential of data sharing in multi-party scenarios. In this chapter, we introduce the basics of blockchain, which are organized into five layers: data layer, network layer, consensus layer, incentive layer and application layer. The details of each layer are elaborated accordingly.
Data-sharing systems are often used to store sensitive data. Both academia and industry have proposed numerous solutions to protect the user privacy and data integrity from a compromised server. Practical state-of-the-art solutions, however, use weak threat models based on centralized trust —they assume that part of the server will remain uncompromised, or that the adversary will not perform active attacks. We propose Ghostor, a data-sharing system that, using only decentralized trust , 1 hides user identities from the server, and 2 allows users to detect server-side integrity violations. To achieve 1 , Ghostor avoids keeping any per-user state at the server, requiring us to redesign the system to avoid common paradigms like per-user authentication and user-specific mailboxes. To achieve 2 , Ghostor develops a technique called verifiable anonymous history.
With the development of big data, data sharing has become increasingly popular and important in optimizing resource allocation and improving information utilization. However, the expansion of data sharing means there is an urgent need to address the issue of the privacy protection - an area where the emerging blockchain technology offers considerable advantages. Although there are a large number of research papers on data sharing modeling and analysis of network security, there are few books dedicated to blockchain-based secure data sharing. Filing this gap in the literature, the book proposes a new data-sharing model based on the blockchain system, which is being increasingly used in medical and credit reporting contexts.
