“…For instance, a random position in the legitimate range is reported back instead of the exact location of the user, as long as the user is still in the permitted area. Spatial cloaking [34][35][36], also referred to as location cloaking or location blurring, is a technique used to blur the user's exact location with a bigger area, called a "cloaked region." It is reported that location privacy depends strongly on the size of the cloaked region.…”

Today, many organizations allow their employees to bring their own smartphones or tablets to work and to access the corporate network, which is known as a bring your own device (BYOD). However, many such companies overlook potential security risks concerning privacy and confidentiality. This paper provides a review of existing literature concerning the preservation of privacy and confidentiality, with a focus on recent trends in the use of BYOD. This review spans a large spectrum of information security research, ranging from management (risk and policy) to technical aspects of privacy and confidentiality in BYOD. Furthermore, this study proposes a policy-based framework for preserving data confidentiality in BYOD. This framework considers a number of aspects of information security and corresponding techniques, such as policy, location privacy, centralized control, cryptography, and operating system level security, which have been omitted in previous studies. The main contribution is to investigate recent trends concerning the preservation of confidentiality in BYOD from the perspective of information security and to analyze the critical and comprehensive factors needed to strengthen data privacy in BYOD. Finally, this paper provides a foundation for developing the concept of preserving confidentiality in BYOD and describes the key technical and organizational challenges faced by BYOD-friendly organizations.

“…When a user makes a server request, the anonymous server will use the locations of other users in the group to which it belongs to construct the anonymous region. Subsequently, Li and Zhu [34] also used the method of regionalization to research on reducing the area of anonymous regions and improving the quality of service. e anonymous server firstly constructs an anonymous region containing k users and then removes the anonymous regions that do not contain the users according to relationship among the users' locations to form multiple anonymous subregions that do not intersect each other.…”

Along with the rapid development of smart campus, the deployment of novel learning applications for smart campus requires full consideration of information security issues. Location privacy protection is one of the most important issues, which considers the privacy protection and guarantees the quality of service. The existing schemes did not consider the area of the querying regions for location-based service provider (LSP) during the construction of the anonymous regions, which led to the low quality of service. To deal with this problem, the user’s query range was introduced to present a novel anonymous region construction scheme. In the proposal, the anonymous server first generated the original anonymous subregions according to the user’s privacy requirements, and then merged these subregions to construct the anonymity regions submitted to LSP based on the size of corresponding querying regions. The security and experiment analysis show that the proposed scheme not only protects the user’s privacy effectively but also decreases the area of LSP querying regions and the region-constructing time, improving the quality of service for smart campus.

“…Protecting the user privacy with locationanonymity, however, is not enough to protect her or his location information when the users are located within an area small enough to locate the user precisely. Location obfuscation approach [3][4][5] is used to decrease the precision of a position so that the attacker can only receive coarse-grained position information. A cloaked region, which is larger than a user-specified threshold, called minimum acceptable area, will be sent to the service provider instead of the exact location.…”

As location-based services have become popular, thereby exposed user locations raised serious privacy concerns. A typical measure for location privacy is to report blurred locations and ensure that other users coexist in the reported region. However, additional knowledge about the user's maximum speed and the territorial information in user's vicinity can allow for the adversary to effectively compromise the user's location privacy. In this paper, we present an anonymization algorithm that effectively counters such attacks while achieving k-anonymity requirements as well as minimum acceptable cloaked region size. We evaluate our anonymization scheme using state-of-the-art simulators for both vehicular movements and pedestrian movements. The experimental results demonstrate the effectiveness and efficiency of our proposed algorithm.
