  2. Outline CSP315- Bluetooth Attendance System

  3. Motivation • Taking attendance in large classes is • cumbersome • repetitive • Consumes valuable class time • Universality of mobile phones motivates to make better use of this technology. CSP315- Bluetooth Attendance System

  4. Objectives • Automating user identification via Bluetooth protocol. • Develop and Implement attendance system . • Create an android mobile application to provide a consistent UI to interact with the system. CSP315- Bluetooth Attendance System

  10. Web Service Design CSP315- Bluetooth Attendance System

  11. High Level Architecture Of Web Server CSP315- Bluetooth Attendance System

  12. Web Site Design CSP315- Bluetooth Attendance System

  13. Professor/Host CSP315- Bluetooth Attendance System

  14. Bluetooth Activity CSP315- Bluetooth Attendance System

  15. Interesting Decisions CSP315- Bluetooth Attendance System

  16. Points of Discussion • Proxy Attendance • Persistent problem that needs to be addressed • Need a robust solution • Present Ideas: • Random checks by professor. • Manual verification of headcount. CSP315- Bluetooth Attendance System

  17. Points of Discussion • Creation of simple app to authenticate student • E.g. Entering a password for verification • Does not solve proxy problem • Can cause distraction during class CSP315- Bluetooth Attendance System

  18. Ease of Use on Mobile Application • Mobile app to have features for enabling plugins. • Some examples of plugins are: • Automatically take attendance as per schedule. • Proxy attendance based (discussed earlier). CSP315- Bluetooth Attendance System

  19. Database Features • Integration with Kerberos Authentication. • Providing secure and encrypted access to the database. • Automated Initialization of the database for courses. • Permission Centric model with different privileges to each kind of user. • Provision of administrative users to police entire setup.

  25. Immediate Steps CSP315- Bluetooth Attendance System

  26. Tasks and Scheduling CSP315- Bluetooth Attendance System

  27. Task Distribution CSP315- Bluetooth Attendance System

  28. Task Distribution CSP315- Bluetooth Attendance System

  29. Hiccups • Delay in procuring android phone. • Procured two weeks before semester started. • Rescheduled plan accordingly. • Unable to access database from entire campus network • Solved by setting up database on poorvi.cse.iitd.ac.in CSP315- Bluetooth Attendance System

  30. Hiccups • Windows Phone 7 • Bluetooth API not exposed in Mango ( ver. 7.5) • Bluetooth API expected to be out in Next Update -2012. CSP315- Bluetooth Attendance System

  34. Design Details CSP315- Bluetooth Attendance System

  35. Recap CSP315- Bluetooth Attendance System

  36. Android App Re-imagined CSP315- Bluetooth Attendance System

  37. Android App Re-imagined CSP315- Bluetooth Attendance System

  38. Android App Re-imagined CSP315- Bluetooth Attendance System

  39. Android App Re-imagined CSP315- Bluetooth Attendance System

  40. Android App Re-imagined CSP315- Bluetooth Attendance System

  41. Permission Model - Choices Person Centric Course Centric Create list of people who can edit the attendance logs of one person. [ta’s , profs, course coordinator] Very Rigorous. Pretty Cumbersome. Create list of privileged people for each course. Each of these people can edit attendance of any attendee. Less rigorous. More Flexible and very practical CSP315- Bluetooth Attendance System

  42. Project Status CSP315- Bluetooth Attendance System

  43. LDAP & Kerberos Integration • Automated initialization from LDAP • List of courses • List of attendees • Course Coordinators • Identification of user groups • Integrated with the Kerberos authentication CSP315- Bluetooth Attendance System

  44. LDAP Integration - Leaks • Only course coordinator in LDAP • Other profs have to manually registered for each course with super privileges. • TA’s are not available in LDAP. • Any super of the course can manually add TA’s CSP315- Bluetooth Attendance System

  45. Initialization Of Database On App • Relevant Data is sent over to the app on initialization. • Codes: • CA: Course Add • CD: Course Delete • SA : Student Add • SM : Student Modify • SD : Student Delete • SP: Student Proxy CSP315- Bluetooth Attendance System

  46. Networking : Server <-> App • Transaction Of Attendance Logs • Transaction Of Updated Mac Addresses • Transaction Of Proxy Attendance • JSON encoding is used for transaction of strings. CSP315- Bluetooth Attendance System

  47. Network Security • Web server uses https(128 bit encryption) for all communications • Web site • Android app • Installation of website certificate is integrated with the app installation (automatic). CSP315- Bluetooth Attendance System

  48. Next Actions CSP315- Bluetooth Attendance System

  49. How to get MAC addresses? • Proposed Solutions: • Direct Input from user • User looks up bluetooth MAC address and enters into profile via webpage • Different Procedures as per manufacturer of the phone • Windows Program • Design of windows program • Display a list of Bluetooth Connections in range and corresponding MAC addresses. CSP315- Bluetooth Attendance System

  50. Experimentation • Run experiment in Labs • Short circuits: • User registration • Course Attendees Lookup • Data to be recorded: • Number of people present. • Number of people found to be present. • Maximum distance to which a person was registered present. • Number of people in proximity but not marked present.
