Sharing data safely while preserving privacy

Accessing Data while Preserving Privacy

As organizations struggle with vast amounts of data, outsourcing sensitive data to third parties becomes a necessity. To protect the data, various cryptographic techniques are used in outsourced database systems to ensure data privacy, while allowing efficient querying. Recent attacks on such systems (e.g., [37, 30]) demonstrate that outsourced database systems must trade-off efficiency and pri...

Privacy-preserving heterogeneous health data sharing

OBJECTIVE Privacy-preserving data publishing addresses the problem of disclosing sensitive data when mining for useful information. Among existing privacy models, ε-differential privacy provides one of the strongest privacy guarantees and makes no assumptions about an adversary's background knowledge. All existing solutions that ensure ε-differential privacy handle the problem of disclosing rel...
