Avoid Key Logger Attacks Using Blank Virtual Onscreen Keyboard

Keyloggers are hardware or software tools that record keyboard strokes. They are a threat during authentication as they can steal important information from the target computers through hidden installation. Nowadays to avoid keylogger attacks, virtual on-screen keyboards are used. But the keylogger has control over the entire Personal Computer (PC) and can read the video buffer. A novel authentication scheme is proposed using blank onscreen keyboard known as password based authentication protocol.
