Abstract
In this work we study certain aspects of the problem of watermarking images, not for the classical example of ownership identification, but instead for embedding a unique identifier that can act as a "serial number" for the image in which it is embedded. In this context, two fundamental questions are: (a) what is the maximum number of different watermarks that can be distinguished reliably? (b) what are good design techniques for watermarking methods to approximate that maximum? Under the...Keywords
