Robust and Secure Image Fingerprinting Learned by Neural Network
摘要： Image ?ngerprinting is a technique that summarizes the perceptual characteristics of digital image into an invariant digest, and it is one of the most effective solutions for digital right management. Most conventional ?ngerprinting algorithms were developed by assembling manually designed feature extractor and quantizer, which requires extensive expert knowledge and may not capture the intrinsic or abstract visual characteristics of digital image. Focusing on content identi?cation related applications, we propose a data-driven image ?ngerprinting algorithm in this paper, where neural network is trained to automatically discover the optimal mapping from image to ?ngerprint. To ameliorate the dif?culty of training, we start by training the ?ngerprint-computation network in a layer-wise manner to progressively improve its robustness against content-preserving distortions. Initialized by the states learned by layer-wise training, the network is then re-trained as a holistic unit, with the objective of maximizing its content identi?cation accuracy. Moreover, we also develop a key-dependent version of the neural network based ?ngerprinting algorithm. By quantifying its security using information-theoretic metrics, we have proved that the hierarchical architecture of neural network is bene?cial to the security of ?ngerprinting algorithm. The experimental results on a large testing database show that the proposed work exhibits much higher content identi?cation accuracy than state-of-the-art algorithms, and its execution speed is in the millisecond time scale.

摘要： In this letter, a new single-anchor indoor localization concept employing electronically steerable parasitic array radiator (ESPAR) antenna has been proposed. The new concept uses a simple ?ngerprinting algorithm adopted to work with directional main beam and narrow minimum radiation patterns of ESPAR antenna that scans 360 area around the base station, while the signal strength received from a mobile terminal is being recorded for each con?guration. The letter describes the antenna design and necessary ?ngerprinting algorithm expansion and shows measurements of the proof-of-concept prototype performed within the experimental setup. Localization results obtained from indoor measurements indicate that the proposed concept can provide better results than the similar approach based on a switched-beam antenna introduced by Giorgetti et al. (IEEE Commun. Lett., vol. 13, no. 1, pp. 58–60, Jan. 2009).

摘要： Software-de?ned networking (SDN) eases network management by centralizing the control plane and separating it from the data plane. The separation of planes in SDN, however, introduces new vulnerabilities in SDN networks, since the difference in processing packets at each plane allows an adversary to ?ngerprint the network’s packet-forwarding logic. In this paper, we study the feasibility of ?ngerprinting the controller-switch interactions by a remote adversary, whose aim is to acquire knowledge about speci?c ?ow rules that are installed at the switches. This knowledge empowers the adversary with a better understanding of the network’s packet-forwarding logic and exposes the network to a number of threats. In this paper, we collect measurements from hosts located across the globe using a realistic SDN network comprising of OpenFlow hardware and software switches. We show that, by leveraging information from the RTT and packet-pair dispersion of the exchanged packets, ?ngerprinting attacks on SDN networks succeed with overwhelming probability. We additionally show that these attacks are not restricted to active adversaries, but can also be mounted by passive adversaries that only monitor traf?c exchanged with the SDN network. Finally, we discuss the implications of these attacks on the security of SDN networks, and we present and evaluate an ef?cient countermeasure to strengthen SDN networks against ?ngerprinting. Our results demonstrate the effectiveness of our countermeasure in deterring ?ngerprinting attacks on SDN networks.
