A Privacy-Preserving Classification Method Based on Singular Value Decomposition

With the development of data mining technologies, privacy protection has become a challenge for data mining applications in many fields. To solve this problem, many privacy-preserving data mining methods have been proposed. One important type of such methods is based on Singular Value Decomposition (SVD). The SVD-based method provides perturbed data instead of original data, and users extract o...

Privacy Preserving Web-Based Email

Location-based services require users to continuously report their location to a potentially untrusted server to obtain services based on their location, which can expose them to privacy risks. The system only requires a semi-trusted third party, responsible for carrying out simple matching operations correctly. This semi-trusted third party does not have any information about a user’s location...
