 To avoid strangers using others’ keys, cards, and passwords to enter the buildings, our team will develop a face recognition-based security system, which offers higher protection of access control and building security.

 New Employees or Visitors  Human Resource or Security Department  Security Personnel

 The ABC company has several buildings for each department.  Each building requires different security clearance levels.  The security officer in each building will use an android phone to identify individuals by taking pictures, and decide whether or not to let individuals into the building.

 Android App:  Android Phone  Phone Interface  Database  Database Interface  Face Recognition Interface  Training App:  Web GUI

 Use camera - Take a photo.  Send photo to Phone Interface (invoke recognize procedure).  Wait for response while displaying progress to user.  Display the data or exception message (depending on whether the face has been detected or not).

 Receives JPEG photo from the Android phone.  Makes sure that the photo sent by the phone is in a correct format and invokes Face Recognition Interface recognize procedure.  Waits for a response and receives XML/JSON file containing data from Database Interface or an error message depending on recognition success/failure.  Forwards the above data/message to the phone device.

 Needs to be able to store Unique ID (int), First name (30 char), Last name (30 char), Job Title (40 char), Clearance Level (int) and Default Photo (binary blob).

 Receive the Unique ID from Face Recognition Interface and do a search query on the database for that ID.  Sends First Name, Last Name, Job Title, Clearance Level and Default Photo for that particular ID to Phone Interface via XML/JSON.  Stores data to the local database.

 Recognize procedure - receive JPEG photo and send it to face.com for evaluation.  Train procedure - receive batch of JPEG photo(s) and send them to face.com for training purposes.  Get response from face.com and forward it to appropriate interface.

 Should have some form of authentication for the user who is training the software.  Should ask for First and Last Name of the person as well as Job Title.  Should generate an integer Unique ID (Primary key)  Clearance Level (We assume that the security guard knows the clearance level for the building)

 Form to upload a batch of photo(s) which will be processed by a script.  Extension for the photo(s) should be.jpeg and have good resolution and contrast.  The Web App should send the photo(s) to the Face Recognition Interface, as well as the unique ID and name.  Upon training completion Web App should invoke store procedure in Database Interface, storing all the personal info and a unique ID to the local database.

 We divide the original architecture into two parts: the Android App and the Training App.

 Risk 1:  When we use the android app to send a picture to recognize, the system might return more than one matched result.  Mitigation:  Design a priority selection mechanism, which can choose a best one from given results according to a priority rule which is decided by the application performance.

 Risk 2:  Internet connection problems, or long responses.  Mitigation:  Give a prompt message asking the user to try again later.
