Time Granularity-based Privacy Protection for Cloud Metering Systems

A Threshold-based Model for Privacy Protection in Cloud Computing

Privacy for cloud computing has become an important issue in recent years. In this paper, we propose a threshold-based model for privacy protection in cloud computing with a particular (n +1, t +1) secret sharing scheme which is bases on the matrix and vector. We show how our (n +1, t +1) secret sharing scheme can be applied to protect privacy. First, we assign each row of the matrix as a key o...

Privacy Protection for Mobile Cloud Data: A Network Coding Approach

Taking into account of both the huge computing power of intruders and the untrustedness of cloud servers, we develop an enhanced secure pseudonym scheme to protect the privacy of mobile cloud data. To face the huge computing power challenge, we develop an unconditionally secure light-weight network coding pseudonym scheme. For the privacy issue of untrusted cloud server, we further design a two...

Privacy Protection Schemes for Fingerprint Recognition Systems

The deployment of fingerprint recognition systems has always raised concerns related to personal privacy. A fingerprint is permanently associated with an individual and, generally, it cannot be reset if compromised in one application. Given that fingerprints are not a secret, potential misuses besides personal recognition represent privacy threats and may lead to public distrust. Privacy mechan...

Privacy Protection Mechanism for Indoor Positioning Systems

Usage of location based services in indoor environments has grown as the popularity of smart devices has been extended. Location Based Services can be generally classified in Indoor LBS and Outdoor LBS. The most common and well-known Outdoor LBS mechanism is the Global Positioning System (GPS) because of its high coverage and accuracy in outdoor environments. However, GPS is not used for Indoor...
