Abstract: A server receives encrypted data from a protected-resource-requesting device that includes an encrypted combination of the device and user identification. The first server requests a most recent copy of data of a distributed ledger from a randomly selected logged-in workstation. The first server searches for a match of the encrypted data from the first device in the distributed ledger data received from the randomly selected workstation. In response to determining a match, the first server updates a table of a second server with a one-time-password (OTP) and a copy of the encrypted data received from the device. The first server sends the OTP and an instruction to the device to send the OTP and the encrypted data to the second server, which determines whether a match exists. In response to a confirmed match, the first server grants access to the device.

Abstract: Methods and systems for deploying a database are described. In an example, a processor can generate an object that specifies a set of data from the database, a set of dependencies associated with the set of data, and a set of changes applicable to the set of data. The processor can determine a schedule to lock the set of data based on the set of dependencies. The processor can lock the set of data in accordance with the schedule. The processor can apply the set of changes to the set of data. The processor can release the set of data with the applied changes to update the database.
