Amazon is the latest tech giant to set sights on blockchain innovations. The e-commerce giant has won two patents, one of which details a new way of protecting digital signatures. The company has also won a patent that details ways to improve distributed data storage. The new patents come on the heels of the company making patent applications for new cryptocurrency-specific inventions early this year.
Amazon Digital Signature Patent
Filed in April, the first patent details an innovative way of protecting the integrity of encrypted communications and digital signatures. The patent details a way of enabling the generation, distribution, and validation of one-time use cryptographic keys.
Amazon proposes the arranging of keys in a Merkle Tree structure. Such structures are fundamental parts of blockchain systems that enable efficient and secure verification of large body data.
The new structure seeks to enable the delegation of signing authority from a central authority to subordinates authorized to sign on behalf. Likewise, the signature authority should be able to distribute the cryptographic keys for signing delegates. Similarly, signing delegate contacts should be able to contact key distribution service to request a new cryptographic key.
Amazon also outlines a new way that people will have to follow in case of key revocation. In this case, the service will provide the verifying entity with a revocation value linked to the revoked key cryptography.
Blockchain in Data Storage
The second patent, on the other hand, pertains to a new way of leveraging blockchain technology in data storage. The patent suggests the use of a grid encoding technique that uses a group of collected shards. According to the e-commerce giant, the new solution has the potential to minimize storage redundancy. The solution should also enable maximum availability of storage solution as well as durability and a way of recovery.
Amazon is not the first company to leverage blockchain technology in solving data storage redundancy. The likes of Filecoin, Sia, and Storj have also leveraged the technology as part of the push.
