摘要： A system and method enabling information access control of the sensitive information, based on a trust computing platform is provided. The trustworthiness of the information seekers is computed and accordingly the information owner is capacitated to decide upon sharing the information completely or sharing with some perturbation. The objective is to provide the information owner with the ability to decide on sharing its private data with respect to a parameter so that the decision is less subjective. This invention allows minimum leakage of sensitive data and makes information owner aware of the risk of privacy breach when private data is shared.
摘要翻译：提供了一种基于信任计算平台实现敏感信息的信息访问控制的系统和方法。计算信息搜索者的可信度，因此信息所有者具有能力，以完全分享信息或与某些扰动共享。目的是为信息拥有者提供决定分享其私人数据的参数的能力，以便决策不太主观。本发明允许敏感数据的最小泄露，并使信息所有者在共享私有数据时意识到隐私泄露的风险。

摘要： A computer-based system and method for secured privacy preservation scheme while data aggregation in a non-hierarchical wireless sensor network that lacks peer- to-peer communication between the communicating sensor nodes is disclosed. The method and system adopts formation of. self-adaptive efficient cluster formation for robust privacy preservation in the network by grouping the multiple sensor nodes in the network to form multiple clusters that enables low computation overhead and high scalability in the network. The method and system of the invention discloses an effective twin-key management scheme that provides establishment of secure communication among the sensor nodes and the secure communication between at least one sensor node with the sever node performing the function data aggregation of the data collected by the sensor nodes.

摘要： Disclosed is a system and method of utilizing plurality of constrained edge devices for distributed computation. The system enables integration of the edge devices like residential gateways and smart phone into a grid of distributed computation. The edged devices with constrained bandwidth, energy, computation capabilities and combination thereof are optimized dynamically based on condition of communication network. The system further enables scheduling and segregation of data, to be analyzed, between the edge devices. The system may further be configured to preserve privacy associated with the data while sharing the data between the plurality of devices during computation.

摘要： Method(s) and system(s) for providing an optimal trade off point between privacy of a private data and utility of a utility application thereof are described. The method includes quantifying privacy content of a private data associated with a user based on uniqueness of information in the private data, where the private content comprises sensitive information about the user. The method further includes determining a privacy-utility trade off point model based on analytical analysis of the privacy content, a privacy requirement of the user, and a utility requirement of third party to which the private data is disclosed, where the privacy-utility trade off point model is indicative of optimal private data sharing technique with the third party. Furthermore, the method also includes identifying privacy settings for the user based on risk appetite of the third party, utilizing the determined privacy-utility tradeoff point model..

摘要： The invention relates to a system and a method for privacy preservation of sensitive attributes stored in a database. The invention reduces the complexity and enhances privacy preservation of the database by determining the distribution of sensitive data based on Kurtosis measurement. The invention further determines and compares the optimal value of k- sensitive attributes in k -anonymity data sanitation model with the optimal value of I sensitive attributes in / diversity data sanitation model using adversary information gain. The invention reduces the complexity of the method for preserving privacy by applying k anonymity only, when the distribution of the sensitive data is leptokurtic and optimal value of k is greater than the optimal value of /.
