Abstract :
An efficient secure single-sensor camera for captured image copyright protection and ownership authentication is introduced. Visible watermarks are embedded during the colour filter array (CFA) data acquisition process. Subsequent demosaicking of the watermarked CFA grey-scale images generates secure full-colour images readily available for storage or distribution.
