Circumventing keyloggers and screendumps

We consider keyloggers (hardware or software) and screendumps of virtual keyboards by the local machine. To counter these attacks, we use DirectX 9 libraries[3] on Windows or Linux[5] operating systems. Our approach uses a remote server that communicates securely with the local process. The Direct X mode that we use executes in the GPU while being directly displayed on the screen. There is no direct communication between the operating system and the GPU storage, which allows us to communicate with the user securely even if the local machine is compromised. We present a simple prototype application of this approach, which supports web browsing.
