State-of-the-art internet banking sites like this one are very secure. Let us give you an example to illustrate the extraordinary precautions we go through to protect your personal data.
Imagine sending a friend a letter. It's as simple as dropping it in a mailbox for the carrier to pick up and deliver. Now imagine that before dropping it into the mailbox, you put the letter through a shredder that only you have the key to. And instead of one carrier coming to pick it up, the post office sends 100 carriers, each of whom take one shred of your letter. They all take a different route through all sorts of neighborhoods to your friend's house. Once there, your friend takes this pile of incomprehensible paper, puts it through a reverse shredder that only he has the key to, and out comes your letter, safe and sound. That's the equivalent of what happens when data is transmitted on this website. If we sent information through the traditional manner of one letter, one carrier, and one route, it would be easy for a criminal to find the truck carrying your letter and pick it out. So we use the 100-carrier method, otherwise known as RSA public-key cryptography. It's become a standard on the Internet wherever private or sensitive information is concerned. The government uses it, the financial industry uses it, and now, so can you.
