Privacy Preservation in Social Networks: Detailed Scope and Techniques

The dissertation should be approximately 14,400 words and should adhere to standard academic research protocols.

Please provide:

1. A comprehensive review of the existing literature on privacy-preserving techniques in movie rating systems, specifically focusing on either Netflix or IMDb.

2. An in-depth analysis of the chosen platform’s privacy issues and existing privacy-preserving methods.

3. Proposed solutions for enhancing privacy preservation in the chosen platform, supported by theoretical arguments and potential practical applications.

4. A critical evaluation of the impact of enhanced privacy-preserving methods on user trust and experience.

The writer has the liberty to choose between the two topics:

1. Privacy-Preserving Techniques in Netflix’s Rating System.

2. Privacy-Preserving Techniques in IMDb’s Rating System.

Please note that while the writer can choose between the two topics, the work should be in-depth, comprehensive, and the writer should demonstrate a strong understanding of privacy-preserving techniques in the context of movie rating systems. Plagiarism will not be accepted and the work should include proper referencing in a predefined format.

It’s important to add that this task should not be completed using AI writing tools. The work needs to be original and demonstrate critical thinking, analysis, and synthesis. Any evidence of AI-assisted writing will result in immediate termination of the agreement.

The Dissertation

The Dissertation should contain a full and coherent account of your work. Although there will be an opportunity to present your work orally, and demonstrate any software, the major part of the assessment will be based on the written material in your Dissertation.  You can expect help and feedback from your supervisor, but the final submission is ultimately your own responsibility.  The Dissertation should be written in an objective style, in the third person impersonal tense: e.g., “The following software was developed….” not “I developed the following software….”

The format of the Dissertation

The Dissertation should provide a detailed description of the research carried out by the student. It should be as concise as possible, with an indicative length of 14,400 words.

The formatting should be;

• Text should be 12pt with 1.5 line spacing.
• Font should be Arial or Times New Roman.
• Pages should be numbered
• Sections and sub sections should be titled and numbered
• Diagrams and Tables should be numbered and have captions

The structure and key features of the Dissertation

The text should concise with any additional material (instructions, questionnaires, code listings, etc) placed in the appendices. A generalised structure for a Dissertation is outlined in this section, however you should however be guided by your supervisor as to what is the most appropriate structure to suit your particular project.

• Title Page – This should include project title, the M.Sc. course, the student name and enrolment number, year of study, names of first and second supervisors.
• Declaration – The standard declaration should be included and signed. A copy is provided at the back of this handbook.
• Abstract – A brief (150 Word Max.) statement summarising your work. It should include the aims of your project; the methods you use to achieve your results and your conclusions. It should be as factual as possible.
• Acknowledgements – Anyone you wish to thank.
• Contents Pages – This should list the chapter headings and subheadings. It should also contain a list of illustrations, abbreviations, appendices and relevant page number.
• Chapter 1 – The introductory chapter should start with an outline of the problem that has been investigated and should contain the following subsections
  • A clear statement of the aim and objectives of the project.
  • An outline of the contents of further chapters in the Dissertation

It may also contain if appropriate

• How much of the content is the author’s own work. If the Dissertation describes work resulting from a team project or further work on an ongoing or previous research project, the contribution of the author should be clarified, and those sections of the Dissertation, which describe the author’s, own work should be clearly indicated.
• Chapter 2 – The Literature Review. This chapter should be an outline of the problem and a survey of what has already been done in this field, and what are the main existing ideas, methods, techniques, products, guidelines, principles, theories, etc. relevant to the project. In all cases this will involve a critical review of published literature (books, journal and conference papers, technical reports, software documentation, etc.).  It should assume the reader is computer-literate, but not necessarily an expert in the specific area of your Dissertation. Even where readers are experts, they will be looking for evidence that you can explain the field clearly to a non-expert.
• The intermediate chapters – the structure will depend on the nature of your project. There may be chapters on some of the following; methodology, software design and development, the experiment, data collection, data analysis, software evaluation, experiment results.
• The Dissertation should contain a clear section or chapter where the work in the project is critically reviewed. In all cases, the text should be concise, logically structured and readily understandable without excessive detail.
• The final chapter – The conclusions are those things that have been discovered as a result of you having done the work. What do you know now that you didn’t know before completing your project?  This final chapter contains concise statements of what you have achieved, and what is special, new, significant or wonderful about it.  Reflect back on your aim and objectives, to what extent have they been achieved? Conclusions should be justified by work reported in the Dissertation. Refer to sections in previous chapters, and/or restate any significant results, statistics etc.  It should contain a review of further work, i.e. how your work could be taken forward, the issues it raises, the avenues you would like to have explored had time permitted.
• References – These are dealt with in more detail in section 10.
• Appendices – These should contain details not included in the text including source code, survey results etc. These should contain detailed information not required on a first reading of the main text, but necessary for closer study of the project and in particular its continuation or replication.

Submitting the Project

The project (dissertation and Artefact) must be submitted by 23:59 August 2023.

If the artefact is a piece of software, then the software and any required libraries or associated test utilities should be uploaded. Include the raw code files. Include an executable file as well if appropriate. Raw data from user evaluation should also be included, e.g. completed questionnaires, transcripts of interviews, etc..

• If the artefact is the design and execution of an experimental study, then the raw experimental data and any analysis tools (for instance spreadsheets, or SPSS files) should be uploaded.
• If the artefact is a document, then the document should be uploaded. Remember, the artefact document is a separate, stand-alone document, it is not part of the dissertation. Raw data from the evaluation of the document should also be included, e.g. transcripts of interviews etc.
• If the artefact is a primary data gathering and analysis exercise, then the raw data should be uploaded, along with the statistical analysis tools used tools (for instance spreadsheets, or SPSS files).
