- Detecting privacy problems that originate from insufficient security within Android applications, looking from different perspectives (e.g., multiple static analysis tools vs multiple dynamic analysis tools).
- Defining and building a multi-purpose ontology (ASO) of security issues in the context of Android applications.
- Using ASO to translate and aggregate reports from different Android application analysis tools, so to create an automation-friendly final security report.
- Using the aforementioned final report, together with a model of the law on data protection to perform logical reasoning, in order to infer undetected security issues, and detect violation of the law, and predict legal consequences.
We developed ASO, an Android Security Ontology which models the security problems that can be encountered within Android applications. A visualisation of ASO is available here.
We are developing an agent platform, MagnetDroid, which performs a parallel analysis of a given Android apk with the available analysis tools, retrieves, translates, and aggregates the reports.
We are developing a post-analysis framework that, given the final report and a model of the law, can perform logical reasoning to detect violations of the prescription of the law, and predict legal consequences (such as fines).

COMMODITY12 proposed a four-layered platform structured as follows:
- Body Area Network Layer (BAN): this layer employs sensors to monitor the patient physiological signals and performs multi-parametric aggregation of data for the Smart Hub layer.
- The Smart Hub Layer (SHL): this layer receives aggregated data from the BAN and applies machine learning to classify the signals and provide indications about abnormalities in the curves. SHL will communicate with DRR over the cell-phone network.
- The Data Representation And Retrieval Layer (DRR): this layer interfaces to the SHL and utilises existing medical data to perform information retrieval and produce structured information for the agents at the AIL.
- The Artificial Intelligence Layer (AIL): this layer uses the DRR layer to retrieve structured background knowledge of the patient for intelligent agents applying diagnostic reasoning in order to advise on the patient’s condition.

Within ARGUGRID, agents are associated with service requestors and service providers. The agents encompass the logic for internal decision making and are equipped with methods for negotiation with other agents. With the support of argumentation processes, the agents decide which services can be used for fulfilling the demands of users and also how to create, manage and join virtual organisations, understood as societies of agents, to compose individual services into more complex ones.
The work focused on e-business application scenarios, but its results are outreaching to all kinds of applications.

The project had three phases: phase 1 – formal models; phase 2 – computational models; and phase 3 – verification and experiments. During phase 1, we undertook studies that integrate hypothetical, temporal and argumentation-based reasoning in order to model logically individual computees. We then developed a logical framework for interactions amongst computees. This will establish interactions amongst computees via direct communication, whether based on standard protocols or emerging from individual communicative behaviours. In phase 2 we developed computational models for the logical models of individual computees and their interactions. To support these computational models, a complete experimental demonstrator was developed which was tested on scenarios and examples on varying scales. Finally in phase 3, we identified significant and desirable properties of computees and their societies, and proved formally under what circumstances these properties hold. Results were validated using the prototype demonstrator embodying the formal models.
The techniques developed provided a practical basis for the design of classes of systems and applications, which require aggregate behaviour of computational entities. For more details see here.
