The potential of 3D printing to revolutionize manufacturing is becoming today a reality. Also referred to a class of Additive Manufacturing (AM) technologies, 3D printing enables mass customization and manufacturing of device components, parts of houses, human organs and even food. It reduces production costs, manufacturing time, and necessary storage space. Due to this success, the protection of Intellectual Property Rights (IPR) for 3D printed models raises increased concerns. Among technologies enabling copyright protection, traitor tracing and authentication, 3D watermarking has received a lot of interest from the research community in the context of 3D digital models. In this paper we give an overview of the state of the art of 3D digital watermarking and we assess how it could be extended for ensuring the IPR protection of printed 3D models. By considering 3D printing and scanning as an attack, we evaluate the potential of state-of-the-art watermarking techniques to provide both robust protection and also high fidelity as the introduced shape perturbations should not impair the mechanical properties or functionalities of the printed 3D model.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
