Nvidia patents database search that hides restricted data in real time

Nvidia describes a method for controlling who can see specific records in a database during a search. The system uses a "permission vector" to automatically hide or mask data that a user is not allowed to access while the search is happening.

Why it mattersThis improves data security by ensuring users only see records they are permitted to view, which is useful for organizations managing sensitive information.

In the filing’s own words

Systems and methods are provided for controlling access to records in a database, such as a vector database, during search operations such as vector search operations. At least one embodiment relates to accessing a permission vector indicating access rights for a user to a plurality of records stored in a database, and searching the database using the permission vector to mask access to prohibited records during search traversal.

What exactly they claim (claim 1)

1. One or more processors comprising processing circuitry to perform operations comprising: accessing a permission vector indicating access rights for a user to a plurality of records stored in a database, the access rights indicating one or more prohibited records of the plurality of records; and searching the database using the permission vector to mask access to the one or more prohibited records during search traversal.
