Overview
Privacy plays an essential role in every sector of our society and economy, because privacy breaches can not only cause personal mental anguish and family anxiety but also lead to adverse impacts on the community and society, accompanied by huge economic losses and monetary penalties. Although many countries have released regulatory compliance requirements, policies and laws (e.g., the Australian Privacy Principles (APPs), U.S. Health Insurance Portability and Accountability Act (HIPAA), European Union’s GDPR, etc.) to protect privacy, the current legal and regulatory frameworks for addressing privacy issues are still far behind technological and business developments, especially in the new age of Internet of Things (IoT). Given the pervasive, distributed and interconnected nature of IoT, privacy issues will inevitably become more pronounced, and continuously expose additional risks and weaknesses. Even statistically, the exposed risks and weaknesses will be abused in an IoT environment that involves huge numbers of devices. As a result, it has been claimed that “privacy is one of the main unknowns and sensitive issues raised by the IoT”. Although there have already been available techniques and methods of privacy preservation (e.g., Data Encryption Mechanism, Data Perturbation Mechanism, and De-identification), they are generally applied to the runtime of applications, and they are barely suitable for the IoT environments and for the “big data” processing and communication across a wide range of distributed IoT devices. For example, the heavy computation overhead makes conventional cryptography impractical due to the resource constraints of medical and IoT sensors; multitudinous perturbation mechanisms inevitably sacrifice the data utility; while de-identification can be reversible and can often contravene the data integrity. Therefore, this project argues that it is time to emphasise and re-emphasise the value and power of software architecture for privacy preservation in IoT. For example, by carefully architecting system components and adjusting business logic implementation strategies (e.g., data federation instead of data centralisation), we will be able to guarantee privacy-friendly software systems at design time rather than employ sophisticated privacy-preserving techniques at runtime. In other words, this project will follow the principle of “prevention is better than cure” to investigate novel privacy-preserving solutions, methodologies, patterns and theories for developing user-centric IoT applications.
This project will be unfolded based on the promising early work on an IoT-native privacy preservation and quantification methodology. This early-stage methodology advocates a distributed and disposable fashion to exclude individuals’ sensitive information from data processing. To help judge the efficacy of alternative privacy-preserving solutions/mechanisms, this methodology also includes a privacy quantification framework based on fuzzy logic and privacy risk analysis. It is worth mentioning that compared with the information-theoretic approach, the privacy quantification here essentially follows the empirical software engineering approaches, i.e. quantitatively scaling risks, environmental contexts, and privacy levels via qualitative natural-language discussions. Therefore, this software engineering-intensive PhD project can naturally continue and extend the current research work.
In particular, to better understand the privacy risks and weaknesses of IoT environments, characterising the existing IoT applications and their system architectures will be a crucial and fundamental part of this project. Since it is impractical to directly involve or observe considerable IoT systems within a single PhD project, the PhD student is expected to employ empirical software engineering research methods (e.g., performing secondary studies) to conduct the characterisation work for this project part.
It should be noted that the developed software architectural tactics and patterns are not supposed to replace the existing privacy-preserving techniques and methods. Following the methodological thinking (a methodology refers to “an organised set of principles which guide action in trying to ‘manage’ (in the broad sense) real-world problem situations”), the innovation here also includes guidelines for deciding the right techniques to be used in the right situations, for example, one of the tentative research directions can be: differential privacy + coded computing + federation architecture. In fact, even for the purpose of practical validations, the investigations into some existing privacy-preserving techniques will be necessarily included in this project.

To do a PhD was one of the most challenging but rewarding decisions I have taken. While having a PhD was helpful in the job market, the real benefit was in stretching my mind and deepening my thinking. This is proving particularly useful as I head up a new local R&D team which has to stay ahead of the game by exploiting the latest research.

People teaching you
Course structure
There is no specific course content as such. You are expected to take research training modules that are supported by the School which focus on quantitative and qualitative research methods. You are also expected to carry out your research under the guidance of your supervisor.Over the course of study you can attend postgraduate skills training organised by the Graduate School.
You will normally register, in the first instance, as an ‘undifferentiated PhD student’ which means that you have satisfied staff that you are capable of undertaking a research degree. The decision as to whether you should undertake a PhD is delayed until you have completed ‘differentiation’.
Differentiation takes place about 8-9 months after registration for full time students and about 16-18 months for part time students: You are normally asked to submit work to a panel of up two academics and this is followed up with a formal meeting with the ‘Differentiation Panel’. The Panel then make a judgement about your capacity to continue with your study. Sometimes students are advised to revise their research objectives or to consider submitting their work for an MPhil qualification rather than a doctoral qualification.
To complete with a doctoral qualification you will be required to submit a thesis of approx 80,000 words and you will be required to attend a viva voce [oral examination] with an external and internal examiner to defend your thesis.
A PhD programme runs for 3-4 years full-time or 6-8 years part-time. Students can apply for a writing up year should it be required.
The PhD is open to both full and part time candidates and is often a useful preparation for a career within academia or consultancy.
Full time students are often attracted to research degree programmes because they offer an opportunity to pursue in some depth an area of academic interest.
The part time research degree is an exciting option for professionals already working in the education field who are seeking to extend their knowledge on an issue of professional interest. Often part time candidates choose to research an area that is related to their professional responsibilities.
If you meet the Entry Requirements, the next step is to check whether we can supervise research in your chosen area. We only take students to whom we can offer expert research supervision from one of our academic staff. Therefore, your research question needs to engage with the research interests of one of our staff.
Assessment
- Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present write up their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.
This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.
The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.
Feedback
- Supervisors will offer feedback on the research work at regular intervals throughout the period of registration on the degree.
Facilities
Full time PhD students will have access to a shared office space and access to a desk with personal computer and internet access.

Additional course costs
All Students
Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.
Bench fees
Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
