ZeU Technologies Inc. announced that it has filed a provisional patent application with the US Patent Office entitled Method and system for the safe custody of private data using blockchain.' Blockchain provides secure data storage accessible through a private key. Private key management has proven to be troublesome as approximately US$140 Billion worth of Bitcoin has been `lost' due to forgotten passwords or users otherwise being locked out of their accounts1, the consequence being that the assets stored by those accounts are permanently lost. ZeU's latest patent provides a method for reliably restoring access. This method stores data fingerprints and keys on blockchain while building a safe deposit box for data. The data is divided and stored in multiple parts with built-in redundancies to ensure encrypted data retrieval. The user is required to set challenge tasks when storing the data. The tasks and their answers will be sliced up and sent to multiple custodians. Should the user lose access to the data, the custodians will verify the user's identity through the challenge tasks. After successfully establishing the user's identity, the custodians forward their slices of data to be reassembled, and the user is given access to the data. Redundancies have been built into the system to avoid losses due to custodian failure.
