Abstract
It is recognized herein that a given party might be hesitant to share its data because of privacy concerns, among others. It is further recognized herein that current approaches to sharing data between multiple parties, such as secure multi-party computation, anonymization, or blockchain techniques, do not enable a given party to decide a level of obfuscation associated with its data without the intervention of a third party. In accordance with various embodiments described herein, a given party can determine an obfuscation level associated with its data, thereby instilling confidence in parties that their data is protected and kept private when data is shared and aggregated.
Claims19
A method comprising:
- collecting raw data from one or more devices of an industrial system;
- obtaining a parameter value that relates to an obfuscation associated with the raw data;
- and
- based on the parameter value, generating synthetic data that represents the raw data without disclosing the raw data,
- wherein the synthetic data is further generated so as to protect the raw data in accordance with the obfuscation associated with the raw data.
An obfuscation level decider (OLD) system coupled to one or more devices of an industrial system, the OLD system comprising:
- an input port configured to collect raw data from the one or more devices of the industrial system;
- and
- a generative adversarial network (GAN) configured to:
- obtain a parameter value that relates to an obfuscation associated with the raw data;
- and
- based on the parameter value, generate synthetic data that represents the raw data without disclosing the raw data,
- wherein the synthetic data is further generated so as to protect the raw data in accordance with the obfuscation associated with the raw data.
A system comprising:
- a plurality of industrial networks configured to generate raw data, each industrial network comprising a generative adversarial network (GAN) configured to:
- obtain a parameter value that relates to an obfuscation associated with the raw data;
- and
- based on the parameter value, generate synthetic data that represents the raw data without disclosing the raw data, and
- a collector device coupled to each of the plurality of industrial networks, the collector device configured to obtain and aggregate the synthetic data from the plurality of industrial networks.
