Part A: Case Study (Compulsory)

Ql. Internet users can be intentionally fooled by different websites with similar domain names. Introducing extra characters through IDNs increases this risk. While characters in one alphabet may look identical to characters in another alphabet to a user, they are discriminated by computers. The threat was highlighted by a spoof website forwww.paypal.com using a Cyrillic 'a' rather than a Latin 'a'. Users could receive this link in an email and give personal and financial details on the false site. One solution proposed is for software manufacturers to develop more sophisticated tools for distinguishing scripts. Can you suggest other solutions for the problem. Discuss the pros and cons of the suggestions given by you.
