SECURE WATERMARKING FOR MULTIMEDIA CONTENT PROTECTION: A
REVIEW OF ITS BENEFITS AND OPEN ISSUES
ABSTRACT:
The paper illustrates recent results regarding secure watermarking to the signal processing
community, highlighting both benefits and still opens issues. Secure signal processing, by which
indicates a set of techniques able to process sensitive signals that have been obfuscated either by
encryption or by other privacy-preserving primitives, may offer valuable solutions to the
aforementioned issues. More specifically, the adoption of efficient methods for watermark
embedding or detection on data that have been secured in some way, which we name in short
secure watermarking, provides an elegant way to solve the security concerns of fingerprinting
applications.
