The paper illustrates recent results regarding secure watermarking to the signal processing community, highlighting both benefits and still open 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.
