Gaining the trust of online customers is vital for the success of any company that transfers sensitive data over the Web. When shopping online, consumers are concerned about identity theft and are therefore wary of providing untrusted sources with their personal information, especially their credit card details.  Other types of online businesses require different but equally sensitive information. People are reluctant to provide their national insurance numbers, passwords, or other confidential personal information, or sometimes even just name, address, and phone number. Perhaps the information will be intercepted in transit, they fear, or perhaps the destination itself is manned by imposters with ill intent. The result is an abandoned transaction.
