Diskreto

Diskreto is a privacy-preserving data exchange protocol designed to enable secure sharing of sensitive datasets among multiple organizations without exposing raw data or internal schemas. It aims to balance data utility, privacy, and regulatory compliance by combining cryptographic techniques with governance controls.

Origin and etymology: the name Diskreto is a portmanteau of discrete and protocol, proposed by researchers at the Diskreto Collaborative in 2023 to reflect its emphasis on discrete data handling and verifiable workflows.

Architecture: Diskreto features a two-layer architecture consisting of a core cryptographic protocol layer and a governance and policy layer. The core layer supports secure multi-party computation and zero-knowledge proofs to allow computed analytics over encrypted data without revealing inputs. The policy layer enforces access controls, consent, provenance, and auditing through tamper-evident logs.

Security and privacy: Data remain encrypted in transit and at rest; participants use cryptographic tokens, key management, and differential privacy when publishing results. The system provides end-to-end auditability and supports revocation of access. Potential risks include key compromise, misconfiguration of governance rules, and performance overhead from cryptographic operations.

Implementation and use: Several open-source reference implementations exist in languages such as Rust and Python, and pilot deployments have been reported in healthcare data sharing and cross-border financial reporting. Diskreto implementations typically interoperate with existing data models via adapters and metadata catalogs.

Limitations and reception: Analysts note that Diskreto can add complexity and latency compared with centralized data repositories. Adoption depends on establishing trusted governance, standardized schemas, and cross-organizational policy agreements.
