ABSTRACT
In this paper we propose performance measures and
provide a description of the application of digital wa­
termarking for use in copyright protection of digital im­
ages. The watermarking process we consider involves
embedding visually imperceptible data in a digital im­
age in such a way that it is di#cult to detect or remove,
unless one possesses specific secret information. The
major processes involved in the watermarking processes
are considered, including insertion, attack, and detec­
tion/extraction. Generic features of these processes are
discussed, along with open issues, and areas where ex­
perimentation is likely to prove useful.
1. INTRODUCTION
The term digital watermarking is currently being used
