Patent number: 11914741Abstract: A computer system is configured to receiving a data set from a data provider and automatically save the data set in a quarantine database where copying, moving, and sharing of the data set are restricted until the data set is released by a data provider. The data set is parsed to find and mark portions with potentially sensitive information. At least those parts are reviewed by a data governor, who can confirm, add, edit, or remove markers. Those parts can be visually indicated to the data governor, along with a preview of, metadata about, and analysis of the data set. After reviewing at least the automatically marked portions, the data governor can release the data set to a non-quarantine database where another user can use the data set. The user is restricted from accessing the quarantine database.Type: GrantFiled: August 2, 2021Date of Patent: February 27, 2024Assignee: Palantir Technologies Inc.Inventors: Samuel Szuflita, Alice Yu, Emily Wang, Hao Dang, Megha Arora, Nicholas Gates, Samuel Rogerson
