You are provided with 3000 sample keystrokes for 5 users mentioned above. You can find this data using the ‘Lab 2 User Data' link in the ‘Lab 2' folder on Blackboard. Please note that you only have to download and use the data for your lab group. To find out your lab group, email the TA responsible for this lab who will let you know your group number. If you have a partner for this lab, make sure to list both your names and student numbers, and have your lab partner CC'd in the email to the TA. Please note that the scheduling of the demos for this lab will also be based on the group id number.

All the sample files are in a .txt format. The input in each row of the user data is the collection of values for the following five measurements:

For simplicity, in this implementation we only consider Fly Times and Dwell Times (see below for more detail). The threshold level % would be given as an input during the calculation of D as also described in the following section. Treat each value provided as a base 10 number.

Outputs (of your implementation)

The aim of OKAM is to grant access to files in accordance with the ACM (access control matrix) or ACL (access control list) on the basis of the FAR (False Acceptance Rate) and the FRR (False Rejection Rate) calculations as described in the algorithm below. At the end the program, the output should list the user  id together with a time stamp, and the FAR and FRR values for that user in a section labeled 'For Administrator', and the rights granted to that user, if any according to the ACL or the ACM by display appropriate messages later in a section labeled 'For User'.  

This implementation can be easily combined with a secure database scheme to complete OKAM, however you are not required to implement this second component of the system.
