Method and system for data security, validation, verification and provenance within independent computer systems and digital networks

A method for managing secured data within independent computer systems and digital networks, the method comprising:

• generating a cryptographic data stream by processing original data representing the secured data on a local client device through a cryptographic function;
• generating blinded data by providing the cryptographic data stream to a second cryptographic function;
• generating a blinded signature by providing the generated blinded data and a private key to a third cryptographic function of a storage device being different than the local client device, the private key accessible only to the storage device;
• and
• generating a data secret identifier by providing the generated blinded signature to a fourth cryptographic function, wherein the generated data secret identifier is mathematically binded with the generated cryptographic data stream.

A computer-implemented system for managing secured data within independent computer systems and digital networks, the method comprising:

• a client device for generating a cryptographic data stream by processing original data representing the secured data through a cryptographic function, generating blinded data by providing the cryptographic data stream and a blind factor to a second cryptographic function;
• a verifiable storage device in communication with the client device for generating a blinded signature by processing the generated blinded data and a private key to a third cryptographic function, the private key accessible only to the storage device;
• and
• wherein the client device further generated a data secret identifier by providing the generated blinded signature and the blind factor to a fourth cryptographic function, wherein the generated data secret identifier is mathematically binded with the generated cryptographic data stream, and the storage device is never in possession of the original data and the generated cryptographic data stream.
