Spatial cloaking is a privacy mechanism that is used to hide location information in location-based services by blurring users’ exact locations to meet various privacy requirements, such as entropy, K-anonymity, and minimum area. With the development of technology, people are getting more customized services and personalized solution towards their requests. However, this convenience also exposes users’ privacy to certain risks, since the attackers may illegally identify the users’ locations and even further exploit their personal information. Thus, multiple solutions have been proposed to preserve and enhance users’ privacy when using location-based services. Among all the proposed mechanisms, spatial cloaking is one of the those which have been widely accepted and revised, thus having been integrated in many practical applications. |
