KeeeX by KeeeX SAS is a cybersecurity technology that embeds trust, context metadata, and cryptographic proofs directly into digital files without altering their format or appearance. It allows for the certification, signing, timestamping, and blockchain anchoring of content before distribution, enabling subsequent verification by anyone. KeeeX injects trusted metadata (integrity, source, date) and context metadata (version, tags, links, classification) into files, timestamps them, anchors their footprint on a blockchain, and provides verification capabilities. This solution ensures document integrity, traceability, and authentication, creating an immutable audit trail. KeeeX supports various file formats and integrates with existing workflows and software, operating on a decentralized architecture to reduce reliance on central authorities for document verification and authentication.
