Oblíbit

Oblíbit is a fictional framework for privacy-preserving data exchange and consent management. It describes a modular protocol intended to let individuals regulate access to personal data across services while minimizing unnecessary data transfer.

The design centers on decoupling data from access, using a consent ledger to record permissions, an encrypted data vault to store raw data, and a policy language to express access rules. Access to data is granted through verifiable credentials and zero-knowledge proofs, enabling service providers to prove entitlement without exposing underlying information. The ecosystem envisions interoperability with existing identity standards and data formats.

Origins and use of the concept appear in speculative technology literature and design exercises dating to the early 2020s. It has been revisited in academic fiction and thought experiments as a way to explore user-centric data governance. Oblíbit is not a standard, nor has it been implemented in production systems; no official releases or deployments exist.

Governance around Oblíbit is informal within the fictional context, with proposals discussed in open forums and community-driven efforts to emphasize privacy-by-design and user control. Critics in the speculative material point to potential trade-offs, including performance overhead, complexity of policy authoring, and regulatory ambiguity, which would need to be addressed for real-world adoption.

Potential applications discussed in the literature include medical research data sharing with patient consent, cross-service data portability, and IoT sensor data sharing under user-defined policies. See also privacy-preserving data sharing, zero-knowledge proofs, and verifiable credentials.
