PRIVATE DATA AGGREGATION FRAMEWORK FOR UNTRUSTED SERVERS

Title:

PRIVATE DATA AGGREGATION FRAMEWORK FOR UNTRUSTED SERVERS

Document Type and Number:

WIPO Patent Application WO/2017/176075

Kind Code:

A1

Abstract:

A first device specifies a privacy specification. The privacy specification includes at least a safe zone and a precision parameter may also be specified. A second device, such as an untrusted server, uses the privacy specification to provide guidance to the first device on how to perturb sensitive data. The first device then uses the guidance to transform sensitive data and provides it to the second device. The data transformation permits the first device to share sensitive data in a manner that preserves the privacy of the first user but permits statistics on aggregated data to be generated by an untrusted server.
