How does your school protect your personal information? How does your bank keep hackers from stealing your money? Organizations and individuals use codes to protect data, a process known as **encryption**. Some of the strongest encryption methods have their roots in basic mathematics.

#### Pythagoras, Security Genius

When a computer encrypts information, it puts the data into a new form. To an outside observer, your information has become a random chain of numbers and letters. To make sense of the encrypted data, he would need a key to the code. Hackers try to figure out the keys to various codes, so that they can steal the information you send over the Internet.

The Pythagorean theorem helps some programmers develop encryption methods. They use Pythagorean triples to encrypt and decode data. A **Pythagorean triple** is a set of three positive integers that form a solution set for the equation

As the techniques of hackers grow more sophisticated, computer programmers must develop new encryption methods. They continue to study mathematics, looking for new formulas and patterns that can help them keep your data safe. Encryption is essential for the modern economy. Without these codes, criminals could access your bank account, swipe your personal records, and steal your very identity. They could commit crimes while ensuring that you were blamed. Mathematicians and computer programmers are all that stands between an orderly world and total chaos.
