The application of data obfuscation methods in the information protection system of a public decentralized cloud storage and content processing service is considered. This service is a universal distributed decentralized operating system designed to protect distributed computing. The resulting model provides protection through masking transformations of the personal data of network participants and technical data of their nodes, and through cryptographic methods for protecting calculations in a decentralized cloud. Protection from owners of computing resources serving the cloud provided for the subsystems of user management, access control, transport protocols, billing, and user data.
