  • Publication number: 20250245211
    Abstract: Systems, devices, and techniques are disclosed for verification of backup data across a data pipeline. Records from a first storage may be received at a first end of a data pipeline. The records may be hashed to generate first hashes. A first hash tree may be generated from the first hashes. The records may be received at a second end of the data pipeline. Bits of bitmaps that correspond to the records may be set. The records may be hashed to generate second hashes. The records may be stored in a second storage. A second hash tree may be generated form the second hashes. Using the bitmaps, whether all of the records or any duplicate records were received may be determined. The first hash tree and the second hash tree may be compared to determine if any of the records stored in the second storage are corrupt.

  • Patent number: 11924210
    Abstract: Database systems and methods are provided for authorizing access to a protected resource. One method involves an authorization service automatically assigning a unique alias to a web application and thereafter receiving a request for access to a protected resource on behalf of a user of the web application. In response to the request, the authorization service generates a graphical user interface (GUI) display including a graphical representation of the unique alias automatically assigned to the web application at a client device associated with the user, and thereafter in response to user selection of a GUI element of the GUI display to authorize access, the authorization service obtains an access token associated with the user and the protected resource and transmits the access token to the web application.
