In this emerging era of technology, ensuring data security is a challenge to be provided for systems of different sizes and types. An open source software is presented to allow authorization to a device having sensitive work-related information. In an exemplification of this project, an unlocked device configured to capture images, analyze the images to see who and how many faces are looking at the device and automatically locks the device if detected faces is not recognized as authorized.

... oftware is implemented using open source computer vision (OpenCV) library for image processing operation. The recognizer has been trained with 100 images of each authorized user to generate a dataset on which the system relies to recognize authorized users using openCV python bindings. Voila-Jones algorithm is used to detect faces in images using the built in camera of a system.
