SIT719SecurityandPrivacyIssuesinAnalytics Distinction/High Distinction Task 9.1: Location-basedPrivacyProtection Overview Trajectory data is powerful to many crowdsourcing tasks. For example, Uber and otherservices use the drivers’ geolocation to match the client’s requests. However, there areserious concerns aboutthe privacy ofpublishing the geolocation data. In this Distinction/Higher Distinction Task, you will experiment with machine learningclassification algorithms. Please see more details in the Task description. Before attemptingthis task, please make sure you are already up to date with all previousCredit and Passtasks. TaskDescription Instructions: Suppose that you are hired by a large company that uses the user’s geolocation data asreferences for allocating crowdsourcing tasks. The company has developed good algorithms forallocating tasks based on accurate geolocation data. One of the new business requirements isthat each client can visualize a few nearby crowdsourcing workers before the client finalizes theorder. Displaying the geolocation on Google Maps and alike services is doable. However, theaccurate geolocation data is sensitive and cannot be directly disclosed to the clients. Therefore,the boss has requested you to develop a demo system to protect the privacy of the geolocationdata. Since this is a demo system, the famous dataset named “Gowalla” is provided to simulate thecrowdsourcing workers, which is available athttps://snap.stanford.edu/data/loc-gowalla.html. TheGowalla dataset consists of multiple users’ check-in data with timestamps in five columns, somesample data look like this: [user][check-in time] [latitude] [longitude] [location id]1965142010-07-24T13:45:06Z 53.3648119 -2.2723465833 145064 1965142010-07-24T13:44:58Z53.360511233-2.27636901712759911965142010-07-24T13:44:46Z53.3653895945-2.27540870463764971965142010-07-24T13:44:38Z53.3663709833-2.2700764333985031965142010-07-24T13:44:26Z53.3674087524-2.278381347710434311965142010-07-24T13:44:08Z53.3675663377-2.2786317638817341965142010-07-24T13:43:18Z53.3679640626-2.2792943689207763 1965142010-07-24T13:41:10Z 53.364905 -2.270824 1042822 Youwill need to download the dataset,familiarizewith itbefore performing the following actions: Find three privacy protection methods to protect location-based data from at least three publishedpapers,includingthepaperspublishedonarxiv.org.Write a short literature review (approximately 500 words) to compare the identified methods in at leastthreeaspectsthatarerelevanttodataprivacyand utility.Identify meaningful performance metrics based on your critical literature review and comparisonbeforeproposinghowtomeasurethesemetrics.ImplementorapplytheexistingimplementationsofprivacyprotectionmethodsontheGowalladataset.ReporttheperformancemetricsthatareidentifiedinStep3.DemonstratetheproposedsolutionswithafewcasestudiesusingGooglemaps.

Inreal-world, results are typically delivered as a product/tool/web-app or through a presentation orbysubmitting the report.However,in ourunit,wewill considera reportanda demo only. Here, you need to write a report (at least 2,000 words including the above-mentioned literaturereview) based on the outcome and results you obtained by performing the above steps. Thereport will describe the literature review, the algorithms used, their working principle, keyparameters, and the results. Results should consider all the key performance measures andcomparative results in the form of tables, graphs, etc. The demo should be a 5-minutes long pre-recorded presentation. Submit the PDF report and the demo PPT through OnTrack. You also need to submit the codeseparately (within the “Code for task 9.1” folder) under the assignment tab of the CloudDeakinPythonscript(s) during submission.
