Data confidentiality is a major concern in database systems. Encryption is a useful tool for protecting the confidentiality of sensitive data. However, when data is encrypted, perf...
We propose PASTE, the first differentially private aggregation algorithms for distributed time-series data that offer good practical utility without any trusted server. PASTE add...
Existing approaches for protecting sensitive information stored (outsourced) at external "honest-but-curious" servers are typically based on an overlying layer of encrypt...
