1. An image sensor apparatus, comprising:

  • an image sensor for generating image data in a pixel array corresponding to an optical image; and

    a processor for;

    altering the image data to embed a first feature-dependent code associated with a first feature of the image data and a second feature-dependent code associated with a second feature of the image data, andgenerating a digital image from the altered image data,wherein the first feature-dependent code is embedded at a first fixed location of the pixel array, the second feature-dependent code is embedded at a second fixed location of the pixel array, the first fixed location and second fixed location each corresponding to a different non-overlapping group of pixels within the pixel array, the first and second fixed locations being predetermined based upon a respective type of the first and second features and distinct from a respective location of the first and second features within the image data.
