Abstract
An information handling system camera is secured against unauthorized image captures by a shutter that mechanically closes across the camera lens to block visible light from entering the camera. The shutter integrates an infrared bypass filter that passes through infrared light while blocking visible light so that the camera can support facial recognition when the mechanical shutter secures the camera to prevent unauthorized capture of visual images.
Claims20
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions to process information;
- a memory interfaced with the processor and operable to store the instructions and information;
- a display interfaced with the processor and operable to present the information as visual images;
- a camera disposed in the display and operable to capture an image analyzed to perform facial recognition in a predetermined spectrum;
- and
- a shutter operable to slide to selectively block and expose the camera, the shutter having a filter that passes only light in the predetermined spectrum associated with the facial recognition and filters all visible light when the shutter slides to block the camera, the camera capturing visual images with the visible light when the shutter exposes the camera.
A method for securing an information handling system, the method comprising:
- capturing visual images with a camera of the information handling system in a visual light spectrum;
- sliding a shutter across the camera, the shutter integrating a filter to block all visual spectrum light for the capturing visual images with the camera, the filter passing only a predetermined light spectrum outside of the visual light spectrum to secure the camera from capture of visual images in the visual light spectrum;
- capturing light with the camera in the predetermined light spectrum through the filter;
- and
- applying the captured light of the predetermined light spectrum to perform facial recognition.
An information handling system camera security system comprising:
- a camera operable to capture images in a visible light spectrum and infrared images in an infrared light spectrum, the infrared images applied to perform facial recognition;
- and
- a shutter sliding between a first position that blocks all light in the visible light spectrum from the camera and a second position that exposes the camera, the shutter integrating an infrared pass filter to allow the camera to receive infrared light with the shutter when the shutter blocks the camera, the camera capturing visual images in the visual spectrum when the shutter exposes the camera.
