Geocoding is the process of matching addresses to geographic locations, such as latitudes and longitudes, or local census areas. In many applications, addresses are the key to geo-spatial data analysis and mining. Privacy and confidentiality are of paramount importance when data from, for example, cancer registries or crime databases is geocoded. Various approaches to privacy-preserving data ma...

Today, privacy is a key concept. It is also one which is rapidly evolving with technological advances, and there is no consensus on a single definition for it. In fact, the concept of privacy has been defined in many different ways, ranging from the “right to be left alone” to being a “commodity” that can be bought and sold. In the same time, powerful Ambient Intelligence (AmI) systems are bein...

One of the basic motivations for solving DCOPs is maintaining agents’ privacy. Thus, researchers have evaluated the privacy loss of DCOP algorithms and defined corresponding notions of privacy preservation for secured DCOP algorithms. However, no secured protocol was proposed for Max-Sum, which is among the most studied DCOP algorithms. As part of the ongoing effort of designing secure DCOP alg...

Privacy preservation in the information society is in many respects parallel to environment preservation in the physical world. In this way, “green ICT services” are those achieving functionality and security with minimum invasion of the privacy of individuals, where such an invasion can be regarded as a kind of pollution as harmful in the long run to their moral welfare as physical pollution i...

Vehicular ad hoc networks are tremendously used for safety related applications. A single point of failure may cause great havoc in the network. Security and privacy are the major concerns. Several solutions are addressed to solve these issues. In this paper we analyze the recent trends in authentication and privacy preservation based on the signature size, verification time and anonymity. Our ...

In emerging Health Information Exchange systems (or HIE), a search facility, such as record locator service, is critically important for data sharing across autonomous hospitals. An understudied problem for searching HIE is the privacy preservation – how to protect the patient’s private visit-history data in the search process and how to address innately different privacy and sensitivity for di...
