PARIS - Tennsun -- csky.ai and DuoKey announced today at Vivatech the launch of their integrated secure transcription solution for Microsoft 365. The solution combines csky.ai's offline AI transcription technology with DuoKey's Double Key Encryption (DKE) to enable organisations to transcribe confidential meetings while maintaining complete control over sensitive data in the Microsoft cloud.

The solution processes meeting transcriptions entirely offline using csky.ai's ClearMind device, which runs a large language model locally without internet connectivity. This edge computing approach means sensitive audio never leaves the organisation's premises during transcription. The system can transcribe meetings in real-time, generate entreprise grade minutes in existing organization word templates, agenda point by agenda point and identify people in conversations while operating completely disconnected from external networks. "In a world where trust and privacy are non-negotiable, our solution empowers leadership teams to collaborate, decide, and move faster, without compromising data control" said Hugo Flayac, CEO at csky.ai.

DuoKey's encryption system then secures the transcripts locally using Double Key Encryption (DKE) before storage in Microsoft 365. This method requires two separate encryption keys for data access — one stored in Microsoft Azure Key Vault and another managed through DuoKey's external key management system. The external key management incorporates Multi-Party Computation to distribute key control across multiple secure locations, preventing any single entity from compromising the encryption key.

Organisations can now transcribe board meetings, legal consultations, strategic planning sessions and other confidential discussions without exposing sensitive to third-party services and cloud servers. The offline processing eliminates the exposure risks typically associated with cloud-based AI transcription services, while the double key encryption ensures that neither Microsoft nor unauthorised users can access the stored transcripts.

"Our encryption solution ensures that confidential transcripts are never exposed to cloud-based servers — including Microsoft," said Nagib Aouini, CEO at DuoKey. "Businesses can really benefit from AI transcription capabilities while maintaining the same level of productivity without compromising data security"

The solution addresses compliance requirements for GDPR, HIPAA, and CCPA by keeping data processing on-premises and providing cryptographic controls over stored information. Legal and healthcare organizations, financial institutions, and companies handling intellectual property can use the system to maintain audit trails and meeting records without compromising confidentiality.

Vivatech attendees can discover the csky.ai and DuoKey integration at booth B38 (hall 1), where the technology's real-time AI transcription and secure Microsoft 365 storage solution is be on display from June 11 to 14.
