Identity Fraud.

Identity Fraud is the topic that we were given in our group of three, consisting of Srishti, Aishwarya and me. I have been assigned the following questions; 5 and 6

5) What are the ethical responsibilities of those maintaining the database ?
Before stating the ethical responsibilities of those who maintain the database, we need to have the knowledge of WHO is retaining the database as well as having the satisfaction that the information is safe and secure. In the case of Identity Fraud; police, financial institutions, and government agencies can be a very reliable place to land, if the situation of theft/fraud occurs, although the main basis of protecting and preserving the database is the IT specialists as well as the software provided by them. An ethical responsibility presented to IT specialists is system reliability. System reliability involves installing, updating, keeping hardware working as well as maintaining databases. Each IT specialist must insure the reliability of the software. Another ethical responsibility of the IT professionals, consist of using the correct tools and procedures to test and evaluate the programs before distribution.
IT professionals must also consider the impact they give upon the computer users. Since they have been involved in such a project, they have the ethical responsibility to possibly millions of individuals for ensuring to the best of they're ability, that they know how to accurately retrieve data. Computers will only do what they have been programmed to do, even if its to perform a dangerous act.


6) What are the legal responsibilities of those maintaining the database ?
The database administrators define the schema which consists of the structure of the data in the application. They determine what data needs to be present in the system and how this data has to be represented and organized. They have a duty to interact continuously with the users to understand the data in the system and its use. Database administrators finds about the access restrictions to be defined and defines security checks accordingly. The DBA (database administrators) also defines procedures for backup and recovery. In order to define backup procedures includes specifying what data is to be backed up. Database Administrators have to continously monitor the performance of the queries and take measures to optimize all the queries in the application. The basic legal responsibilities of database administrators, include assuring that every software or application is safe and reliable as well as knowing that the source of the database is trusted and legitimate.
