Blockchain SSD secures edge data integrity

28 April 2021 Computer/Embedded Technology

The increasing ubiquity of AI in everyday applications brings with it concerns regarding data integrity and validation. Innodisk’s newly patented blockchain technology led to its latest SSD solution, the InnoBTS SSD and alleviates these concerns through a sophisticated use of digital signatures and blockchain that is fully software independent.

This new solution combines blockchain technology to secure the valuable data in modern IoT scenarios, such as POS systems at unmanned stores, smart meters and digital ID cards. The important data written to the SSD will create an encrypted hash string that corresponds to the specific data set and the encrypted hash string is spread across the blockchain network, essentially creating a decentralised ledger that is distributed between numerous unique computers. The process is to make an encrypted hash string to be ‘chained’ on the blockchain network. If tampering happens, the chained data is checked with the encrypted hash string on the network, clearly showing any discrepancies.

The InnoBTS SSD incorporates a hardware-run digital signature. Through the sophisticated use of private and public keys given to each file that is sent, the receiver can always verify the correct sender. The SSD creates and secures the private key within an internal safety zone, ensuring maximum private key security. Only the public key will be available for anyone to verify the correct sender.

The resulting solution benefits from the combination of blockchain technology and data streaming to create an industry-leading solution for data integrity at the edge. Removing the need for software eases system integration as well as strengthening data integrity by moving the functions to the more inaccessible SSD firmware.

Innodisk’s solution allows for easy blockchain setup for edge applications that is not reliant on software and connects numerous devices to the blockchain network. This makes the InnoBTS SSD suitable for cutting-edge AI applications such as smart cities, smart vehicles, smart factories and intelligent surveillance.
