A new data-driven economy has arisen in which data are created, gathered, and exchanged (raw or processed) between organizations and individuals. Companies not only collect the data they are generating and analyze them but increasingly rely on third-party data to enhance their business value. Data are no longer an enabler of products, but a product itself that can be monetized.
Data marketplaces are becoming increasingly popular as intermediaries that orchestrate connections between data providers and data consumers. The data market has been dominated mainly by commercial and privately-managed trading platforms with a centralized governance that decide on the rules, policies, etc. That centralized model puts current big players in a clear competitive advantage. In addition, business success on marketplaces has been heavily based on reputation. i.e., how a provider has behaved in the past. This has been a major stopper for the flourish of a truly competitive data economy, where all stakeholders should freely participate under fair competition.
There is, however, light at the end of the tunnel thanks to distributed ledger technologies (DLTs), popularly known as Blockchains. Blockchains are very compelling since they provide important features such as transparency, immutability, and a single source of truth, as well as allowing the creation of smart contracts. Smart contracts are functions or procedures that will be executed by Blockchains whenever triggered. These properties make Blockchains the perfect tools for creating data marketplaces and enable trust between data consumers and providers without a priori reputation. This represents a paradigm shift where trust is no longer based on reputation but on certainty—the certainty that the data trade is going to be executed following the business logic defined in smart contracts.
Moreover, decentralized marketplaces will enable new architectures that will empower users and make rules more transparent and auditable. Distributed marketplaces should also face the remaining challenges of the sector, which are, notably, regulatory complexity, privacy, and the need to guarantee the data owner’s control over the trading of their data.
The purpose of this Special Issue is to gather the latest advances in security and privacy in decentralized data marketplaces, for which we encourage the submission of papers with new results, methods, protocols, architectures or applications. In particular, the topics of interest include (but are not limited to):
- Decentralized marketplaces architectures
- Blockchain-based marketplaces
- Smart contracts
- Payment systems
- Fair exchange
- Federated authentication
- Self-sovereign identity
- Privacy-enabled data storage solutions
- Explicit consent
- Auditing systems
- Conflict resolution
- Data marketplaces for Industry 4.0
- Digital rights management (DRM) and protection
- Disclosure control
