Question: With identity theft becoming widespread, many organizations have moved to encode the Social Security numbers of their customers, suppliers, and employees. Imagine that you are the system administrator for a college campus where the students' Social Security numbers are used as the key field to access student records and are told that you need to extend backward protection to the records of several decades of previous students. Describe the steps you would follow to modify your system. Make sure your solution also removes the student Social Security number on transcripts, course registration forms, student-accessible data screens, student ID cards, health center records, and other record-keeping systems. Finally, identify which individuals on campus would retain access to the Social Security numbers and explain why.
