Blockchain SSD securing radical edge data integrity
Summary
Innodisk has announced its new solution combines blockchain technology to secure the valuable data in recent IoT scenarios, such as POS systems at unmanned stores, smart meters, 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 on the blockchain network, essentially creating a decentralised ledger that is distributed between numerous unique computers. The process is to make the encrypted hash string to be ‘chained’ on the blockchain network. If tampering happens, the chained data is checked with an encrypted hash string on the network, clearly showing any discrepancies. Through the sophisticated use of private and public keys given to each file that is sent, the receiver can always verify the correct sender.
