<p>The statement of the case study that describes the problem set is below:</p>
<p>The software is required for authentication of products that are delivered to customers by field boys in the field. A field boy when delivering the product at the customer"s door would enter a computer generated code (that is printed on a label that is stuck on the product) into their mobile phone and sms it to a predefined number. They would get a response back that is simply, "ok" or "Counterfeit warning: This code is NOT legitimate!" In this way they would be able to authenticate whether the product is real or fake.</p>
