  • Systems and methods for securing cached data stored off-chain in a blockchain-based network
    Patent number: 11283595
    Abstract: A storage server communicating with a backend storage provider, such as a cloud-based provider, performs processes for backing up encrypted data in the backend storage in a data cache shared by multiple decentralized applications, to allow a user of a frontend client to revert to a prior version of an encrypted file if that encrypted file has been compromised by one of the decentralized applications, where the storage server performs no encryption of the data and is not exposed to encryption keys.
    Type: Grant

    Inventors: Yukan Liao, Matthew Little, Jude Nelson, Aaron Blankstein
  • Client-side authentication system and associated method
    Patent number: 11159326
    Abstract: A client-side, bearer token-based decentralized authentication system and associated method are, from a user's perspective, similar to familiar, centralized third-party authentication techniques.
    Type: Grant

  • Systems and methods for encrypting data in backend storage caches shared by multiple decentralized applications
    Patent number: 10664451
    Abstract: In a decentralized system based on a blockchain, a storage server directs the off-chain storage of shared data for multiple decentralized applications in data caches on a backend storage provider, such that a user's client and any authorized decentralized applications can access encrypted data in the data caches, but the storage server performs no encryption of that data and is not exposed to encryption keys and unauthorized decentralized applications cannot access the encrypted data.

  • Platform and associated method for authenticating the identity of a user in a decentralized system without need for a third-party identity service
    Patent number: 10601829
    Abstract: A decentralized application platform and associated method creates an ID that can be used to sign into any decentralized application that follows the platform protocol without having a centralized third party having to vouch for the user's identity.
