Abstract
In digital cameras, light passes through a lens and is detected by an image sensor. The raw frame(s) captured by the sensor is passed through a software stack to obtain an image or video. Any encryption is performed in the software stack. If the software stack is compromised prior to encryption, malicious actors can remotely access sensor data. Encryption and decryption also introduces additional computational load on both transmitter and receiver devices, and can lead to delays in the captured image/ video being available for viewing. This disclosure describes techniques that utilize the physical properties of glass that has been ground up to provide physical and device-specific unique encryption during image capture. The light scattered by a lens made of such glass is detected at an image sensor. Due to the scatter, the captured image is uniquely encrypted based on the physical properties of the glass. The image is passed to the software stack and sent to one or more receiver devices. A device-specific decoder model is trained that can decrypt the image. The decoder model is provided to receiver devices to enable the receiver devices to decrypt the image.
