How to detect an image in Matlab?

MATLAB: Is there a way to process an image for it to be rejected by google reverse image search and tineye?

  • Say , manipulation of header chunks so that the reverse image searches consider the image to be suspicious and reject it . The original quality of the image is to be maintained as far as possible . The intention is to curb cheating in online exams .

  • Answer:

    One way to achieve this will be change the extension of the image to, say .xyz. Make sure this will not be an image format using the windows picture viewer or a similar application. Then, upload and this will not be image searchable. But again, this answer serves correct only if you do not want to view the image in a website.
