O2Face is a state-of-the-art desktop access control program based on our advanced facial recognition technology. It simplifies your Windows log on experience and frees you from creating and remembering complex passwords.

When you log on, O2Face analyzes a captured face image to make sure that particular person is authorized to log on. The process requires no key input from the user – it only requires the person to look into a connected camera device. In less than a second, O2Face "recognizes" the user and immediately logs onto the system. For Windows XP and Vista users, it requires at least 512M of RAM and 100M of hard drive space
