  • Privacy-preserving transformation of continuous data
    Patent number: 11106809
    Abstract: A data processing method receives a set of time-series user data and also receives a privacy requirement of the time-series user data. Next, the time-series user data is transformed using the privacy requirement such that the transforming satisfies differential privacy.
    Type: Grant
    Filed: December 28, 2016
    Date of Patent: August 31, 2021
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Shiva Kasiviswanathan, Hongxia Jin
  • Private dataaggregation framework for untrusted servers
    Patent number: 10956603
    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.
