Supporting designers in modeling privacy for social network sites

Defining Inspection Techniques for Detecting Privacy Problems in Online Social Networks

“…Therefore, we collect indicators that could assist in formulating techniques using the privacy regulation theory defined by Altman as a starting point [12]. This theory has exerted relevant influence on how HCI researchers consider privacy in the context of interactive social systems, as used by [2] to design a privacy model for OSN.…”

“…To address the privacy level aspect, Villela and Prates [2] proposed the Privacy Design Model (PDM). PDM is an epistemic tool to support the design and evaluation of personal information sharing in OSN, with a focus on user privacy.…”

“…Difficulties in finding the desired option or the inability to perform a certain task in relation to privacy do not always occur as a consequence of improper privacy management by the user. On the contrary, such disparities may be the result of the system being based on a restricted model or mechanism of rules that fail to meet the users' needs and intentions [2] [5], causing unwanted privacy defects.…”

“…In the last few years, some technologies have been proposed to support the design and evaluation of OSNs with a focus on user privacy, so that such technologies can be easily articulated and applied by the designers/evaluators of these systems [2] [6] [7] [8]. Many of these previously proposed approaches have been developed to address specific privacy issues in OSNs, such as photo and information management, access control, and data sharing.…”

“…To define these techniques, three basic assumptions were considered: (1) using privacy aspects of related works already existing in the scientific literature; (2) using a set of guidelines to help inspectors reflect on the discrepant situation to find privacy defects [9]; and (3) using a preliminary study to evaluate and refine the set of techniques so that they are actually useful and easy to use.…”
