The important data written to the SSD generates an encrypted hash string corresponding to the specific data set, and the encrypted hash string is spread on the blockchain network, essentially creating a decentralized ledger distributed between different computers. The process is that the encrypted hash string is "chained" on the blockchain network. In the event of tampering, the concatenated data is checked against an encrypted hash string on the network so that any discrepancies are clearly visible.

The InnoBTS™ SSD has a hardware-controlled digital signature. Through the complex use of private and public keys associated with each file sent, the recipient can always verify the correct sender. The SSD creates and secures the private key within an internal security zone, ensuring maximum security of the private key. Only the public key is available for anyone to verify the correct sender.

The new InnoBTS™ SSD series leverages blockchain technology and data streaming to create the best possible solution for data integrity in edge applications. By moving the functions into the inaccessible SSD firmware, data integrity has been improved and system integration made easier.

Innodisk’s solution enables easy blockchain setup for edge applications by eliminating the need for additional software and connecting numerous devices to the blockchain network. Application areas include smart cities, smart vehicles, smart factories, and smart surveillance.
