DESILO DCR and FHE Library

DESILO is a Korean privacy-enhancing technology company headquartered in Seoul, focused on fully homomorphic encryption (FHE) so that data can be processed while still encrypted. Its stated aim is to break down data silos between organizations that cannot share raw data.

The product family has three layers: the DESILO FHE Library as the computation engine, DESILO Private AI for using AI without exposing sensitive data, and DESILO DCR, an FHE-based data clean room. DCR runs statistical and machine-learning analysis on encrypted uploads and reveals results only through distributed decryption by authorized parties. It is deployed in the National Cancer Center's Personal Information Innovation Zone.

• Encrypted analysis: frequency analysis, regression and classification without decryption.
• User-defined functions: analysts run their own functions in the encrypted environment.
• Multi-party key management: results are revealed only when a pre-agreed quorum consents.
• Federated learning: models train in each participant's environment.
• Flexible deployment: SaaS on public cloud or on-premise.
• FHE Library: computation engine focused on speed and ease of use.

• Vietnamese hospitals and research institutes jointly analysing patient and genomic data without moving records.
• Banks cooperating on fraud detection and credit-scoring model validation.
• Government agencies running statistical analysis on administrative data across departments.

• Raw records are never exposed in plaintext during the analysis pipeline.
• Multi-party key management means no single party can decrypt results alone.
• Federated learning keeps data inside each participant's environment.
• Certifications cited include CSAP SaaS Standard and GS Certification Grade 1 in Korea.

Healthcare, finance and public bodies need to analyse sensitive data jointly while personal data rules tighten, and FHE is progressing toward an international standard, with the ISO work reaching the FDIS stage in September 2026 per the company site. Vietnamese hospitals, banks and agencies face similar constraints on sharing citizen data.
