Abstract
Abstract An image capture device is provided with processing circuitry that steganographically embeds plural-bit auxiliary data within the captured image data. The embedding may be accomplished by adding a low level noise signal to the image data, where the noise signal has the auxiliary data encoded therein. Image data output by the device thus conveys auxiliary data that can be used for a variety of purposes.
