Issues in the Development of Location Privacy Theory

Location Privacy in the Era of the Internet of Things and Big Data Analytics

“…The six phases extend early work from more than 45 years ago identifying three phases of input, storage and output [49]. They also extend five phases discussed in [40] by explicitly adding the "processing" phase to acknowledge the important of inferencing capabilities and data analytical techniques that may deduce location from other available evidence.…”

“…It follows and borrows from prior work investigating issues in the development of location privacy theory in general [40], and extends it to the particular environment of the IoT. At this early stage we can hardly purport to fully explain and predict the eventual evolution of the recently-emerged IoT, let alone control it-however we can begin to organize and categorize important "things" such as components and concepts.…”

“…Location privacy may be viewed from many conceptual perspectives [40] and in the context of the present work related to the IoT and big data, we will consider it from an informational privacy perspective. The informational perspective is key to most privacy theories in a technological context, describing privacy as "the claim of individuals, groups, or institutions to determine for themselves when, how, and to what extent information about them is communicated to others."…”

Jano: location-privacy enforcement in mobile and pervasive environments through declarative policies

“…In [20], Minch points out that location privacy can be defined in terms of: Intrusiveness, Seclusion, Boundaries, Control, and Limitation. In our work, users are willing to share their location to third parties and so we focus on control and limitation in the disclosure of location privacy.…”

“…Then, Definition 3 is used to calculate the tag of the rule (lines 20-24) out of the tag of the decide-expression, which are both trivially equal to tag = ce.accuracy != "Medium". Finally, the tag of the policy is calculated applying Definition 5 to every rule disjunction resulting from the expansion of the EXIST quantifiers (lines [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Assuming that the quantifiers groups have 2 and 5 elements, that is, two groups of friends and a condition for each working day, the tag of the policy is the disjunction of 10 equal tags, resulting in the deny reason of ce.accuracy != "Medium", i.e., the expression is denied because the accuracy required is not equal to the "Medium".…”
