A Privacy-Preserving Continuous Location Monitoring System for Location-Based Services

International Journal of Distributed Sensor Networks, 2015
To protect users’ private locations in location-based services, various location anonymization techniques have been proposed. The most commonly used technique is spatial cloaking, which organizes users’ exact locations into cloaked regions (CRs).

MultiRelational k-Anonymity ∗

, 2008
k-Anonymity protects privacy by ensuring that data cannot be linked to a single individual. In a k-anonymous dataset, any identifying information occurs in at least k tuples.

The Sampling Twice Technique for the RSA-based Cryptosystems with Anonymity

, 2005
We say that an encryption scheme or a signature scheme provides anonymity when it is infeasible to determine which user generated a ciphertext or a signature.

Trader Anonymity, Price Formation and Liquidity [PDF]

Using data from the Frankfurt Stock Exchange we analyze price formation and liquidity in a non-anonymous environment with similarities to the floor of the NYSE. Our main hypothesis is that the non-anonymity allows the specialist to assess the probability

The Anonymity Engine, Minimizing Quasi-Identifiers to Strengthen k-Anonymity

, 2017
The k-anonymity model has become a standard for anonymizing data. However, almost all applications of k-anonymity are used to anonymize large data sets of personally identifiable information owned by a trusted third party before being given to analysists
