What Are Data Spaces?
Data spaces are decentralized ecosystems designed to facilitate trusted data exchange. In a data space, different parties—data providers, consumers, and intermediaries—interact within a framework that ensures security, privacy, and compliance. These exchanges typically occur between digital wallets, managed by identity providers, and are supported by connectors that handle the secure transmission of data.
A data space allows individuals or organizations (data providers) to share their data with others (data consumers) while maintaining control over who accesses it and under what conditions. These environments are designed to respect data sovereignty—ensuring data stays within specific legal and regulatory frameworks—and protect the privacy of users. Data spaces foster trust, transparency, and security, making it easier for organizations to share valuable information while reducing risks associated with data breaches.
The Onboarding Process
Identity Verification and Digital Wallets
The onboarding process to a data space starts with identity verification. Users (either data providers or consumers) must submit their identity details to an identity provider. The identity provider verifies the user’s credentials and issues a certificate, confirming the user’s identity. This certificate is stored in a digital wallet, which acts as a secure storage space for the user’s verified identity.
The connector is then used to access the data space. This software or tool is responsible for interacting with the data space, representing the user within the ecosystem, and securely handling the data exchange.
Who Provides the Digital Wallet?
The digital wallet is provided and managed by trusted wallet providers. These could be specialized companies or organizations with experience in managing sensitive data. Wallet providers are responsible for the security of the stored credentials and ensuring that they are only accessible to authorized parties. In some cases, a wallet may also be integrated with the data space platform itself, simplifying the process for users.
Data Sharing and Consumption
Data Providers
A data provider is an individual or organization that has valuable data to share. By being part of a data space, data providers can upload and catalog their data, making it available to trusted data consumers. The reason data providers should participate in a data space is twofold:
Security
Data spaces ensure that the provider’s data is only accessible to authorized consumers, protecting it from unauthorized access or breaches.
Monetization
Providers can set usage conditions, which might include pricing for data consumption, creating new revenue streams. A trusted environment like a data space reduces the friction involved in establishing agreements with consumers and ensures all transactions are traceable and compliant with data privacy laws.
Data Consumers
Data consumers, on the other hand, seek out specific data that can enhance their operations. They can search for and request data from providers within the space. The consumer’s connector ensures that their request is properly verified and compliant with the provider’s conditions before the data is shared.
Consumers benefit from the transparency of the data space, as they can be certain that the data they receive is verified, trustworthy, and sourced from reputable providers.
Ensuring Trust and Traceability
One of the most crucial components of a data space is the Logging House. While data exchanges occur between the two connectors, the logging house records every transaction to ensure traceability. This means that even though the data itself is transferred directly between the connectors (outside of the data space itself), the logging house maintains a secure audit trail.
Data Consumers
The transaction happens directly between the two connectors—without a third-party intermediary inside the data space. This ensures that there is no unnecessary data routing or storage, minimizing the risk of data leakage. The connectors act as trusted agents for both the data provider and consumer, securely handling the data exchange while the logging house ensures that every action is tracked for future reference and compliance.
