4. OAuth

OAuth, the open standard for authorization, bridges the gap between two known entities. The technology uses a token as a credential. If you want to use some website’s data in Facebook, then OAuth might be the authentication method used to connect one data set to another. OAuth is highly specific. For example, you can use an OAuth token to create a secure connection between a Twitter feed and Klout, a service that ranks social media influence.

5. Keystroke Encryption

This technology is heard only at security analyst conferences. In the enterprise, malware infections can cause havoc. One of the worst offenders is a keylogger, which is a piece of software that can record each keystroke. Criminals use them to capture business intelligence data, credit card numbers and bank records.

Keystroke encryption prevents these attacks. Companies such as Strikeforce Technologies invented encryption technology at the hardware layer for companies to increase security detection techniques. Now it's used on more than 4 million computers.
