Data Access Policy Management

View page
US Patent:
20200117826, Apr 16, 2020
Filed:
Oct 16, 2019
Appl. No.:
16/654630
Inventors:
- College Park MD, US
Eric James PERRY - Alexandria VA, US
Steven William TOUW - Rockville MD, US
Barry Ray HAMMEN - Severn MD, US
Adam Carr HAMLIN - Hyattsville MD, US
International Classification:
G06F 21/62
G06F 21/31
G06F 16/2453
G06F 16/2455
G06F 16/2457
Abstract:
A method for automated data access management can include creating a project that manages data access to data sources by a plurality of users, wherein each user has user attributes indicating data access policies for the data sources. The method can also include performing project equalization for the project, wherein the project equalization determines a set of user attributes shared by the users. Additionally, the method can include modifying the user attributes of each user for the project, wherein the user attributes of each user are modified to conform to the set of user attributes determined by the project equalization, and detecting a query to retrieve data from the data source. The method can include modifying the query to produce a modified query by applying the modified user attributes associated with the project to the query and retrieving the data from the data source based on the modified query.

Calculating Differentially Private Queries Using Local Sensitivity On Time Variant Databases

US Patent:
20190065775, Feb 28, 2019
Filed:
Aug 24, 2018
Appl. No.:
16/112035
Inventors:
- College Park MD, US
Kyle Lily - Alexandria VA, US
Joseph Regensburger - Grove City OH, US
Steven Touw - Rockville MD, US
International Classification:
G06F 21/62
G06F 17/30
Abstract:
Systems, methods, and manufactures for enhancing the determination of differential privacy query results. Implementations may include a database; a result cache; a processor; and a media storing instructions that, when executed by the processor, cause the system to perform operations that include obtaining a query of the database; determining that a specificity of the query exceeds a specificity threshold; determining that the result cache lacks any query results of previous queries that are substantially equivalent to the query; partitioning the database into a plurality of groups; determining a query result by executing the query on the plurality of groups; determining a sensitivity of the query and a nominal measurement of the query; determining a noisy result by adding noise to the query result based on the sensitivity and the nominal measurement; storing the noisy result in the result cache; and providing the noisy result in response to the query.
