Model-Privacy

Model-Privacy is a tool to create, annotate and analyse a general purpose user-centric privacy model. This is specified as a Labeled Transition System (LTS). Here, actions on personal data (e.g., a third-party reads personal data) model the change of a user’s state of privacy. Analysis of this model can then determine if actions carried out by an online service conflict with a user’s privacy preferences. Therefore, such a model provides two main benefits:

  • abstraction: the ability to abstract a complex system’s behaviour with regards to personal data and then machine analyze the privacy implications;
  • re-usability: the ability to use the model to analyze a wide range of policies using different analysis algorithms.

Privacy implication analysis

A service’s usage of private data can be analyzed against a user’s privacy preferences to determine the risk of a privacy breach. From this, the implications can be presented to the user along with recommendations on how to manage the risk:

  • Fine-grained privacy aware access control: a cloudbased service’s access control policies can be adapted to match user privacy preferences, blocking some service actions (where these are not critical to the service operation). We present an algorithm to generate the user privacy model (as an LTS) for a service, and identify transitions that should be blocked such that service actions that pose too great a risk to privacy become inaccessible

Install and Run

The tool is made available as a maven project. In order to build the tool, Java 1.8 or higher must be installed on your machine.

To install the tool. Simply download the zip file for the git repository, extract and go to the root folder location. Then type at the command prompt:

mvn  install

To run the tool at any time, type at the command prompt:

mvn  test
