Location Obfuscation
Location obfuscation is a technique used in location-based services or information system An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. From a sociotechnical perspective, information systems are composed by four components: task, people ...s to protect the location of the users by slightly altering, substituting or generalizing their location in order to avoid reflecting their real position. A formal definition of location obfuscation can be "the means of deliberately degrading the quality of information about an individual's location in order to protect that individual's location privacy.M. Duckham, L. Kulik and A. Birtley, "A Formal Model of Obfuscation and Negotiation for Location Privacy." In Proc. Pervasive 2005. LCNC 3468/2005, pp. 243–251, 2005 Obfuscation techniques The most common techniques to perform this change are: * Pseudonyms and the use of third party lo ...

Location-based Service
A location-based service (LBS) is a general term denoting software services which use geographic data and information to provide services or information to users. LBS can be used in a variety of contexts, such as health, indoor object search, entertainment, work, personal life, etc. Commonly used examples of location based services include navigation software, social networking services, location-based advertising, and tracking systems. LBS can also include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. LBS also includes personalized weather services and even location-based games. LBS is critical to many businesses as well as government organizations to drive real insight from data tied to a specific location where activities take place. The spatial patterns that location-related data and services can provide is one of its most powerful and useful aspects where location is a common denominator in all of these ...

Information System
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. From a sociotechnical perspective, information systems are composed by four components: task, people, structure (or roles), and technology. Information systems can be defined as an integration of components for collection, storage and processing of data of which the data is used to provide information, contribute to knowledge as well as digital products that facilitate decision making. A computer information system is a system that is composed of people and computers that processes or interprets information. The term is also sometimes used to simply refer to a computer system with software installed. "Information systems" is also an academic field study about systems with a specific reference to information and the complementary networks of computer hardware and software that people and organizations use to collect, filter, process, cr ...

Spatial Cloaking
Spatial cloaking is a privacy mechanism that is used to satisfy specific privacy requirements by blurring users’ exact locations into cloaked regions. This technique is usually integrated into applications in various environments to minimize the disclosure of private information when users request location-based service. Since the database server does not receive the accurate location information, a set including the satisfying solution would be sent back to the user. General privacy requirements include K-anonymity, maximum area, and minimum area. Background With the emergence and popularity of location-based services, people are getting more personalized services, such as getting the names and locations of nearby restaurants and gas stations. Receiving these services requires users to send their positions either directly or indirectly to the service provider. A user's location information could be shared more than 5000 times in two weeks. Therefore, this convenience also expo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catuscia Palamidessi
Catuscia Palamidessi (born 1959) is a computer scientist whose research topics have included differential privacy, location obfuscation, fairness in machine learning, the logic of concurrent systems, and the design of programming languages that combine logic programming and functional programming. Originally from Italy, she has worked in Italy, the US, and France, where she is a director of research for the French Institute for Research in Computer Science and Automation (Inria). Education and career Palamidessi was born in 1959 in Fucecchio, a small village in Tuscany, and when she began her studies at the University of Pisa, despite the discouragement of her parents, she became the first woman from that village to go to a university. Continuing her studies there, she earned a laurea in 1982 and a Ph.D. in 1988, with Giorgio Levi as her doctoral advisor. She was an assistant professor at the University of Pisa from 1988 to 1992, an associate professor at the University of Geno ...
