“…Though the proposed system protects the privacy of users from surveillance, it does not include any content protection mechanism that could protect the authors' copyrights. Chae et al (2016) proposed a system to prevent privacy data leakage through P2P file distribution systems. The proposed system identifies the sensitive or private data, and removes the information by the privacy data leaking risk factor from the sharing file.…”

Recombined fingerprints have been suggested as a convenient approach to improve the efficiency of anonymous fingerprinting for the legal distribution of copyrighted multimedia contents in P2P systems. The recombination idea is inspired by the principles of mating, recombination and heredity of the DNA sequences of living beings, but applied to binary sequences, like in genetic algorithms. However, the existing recombination-based fingerprinting systems do not provide a convenient solution for collusion resistance, since they require "double-layer" fingerprinting codes, making the practical implementation of such systems a challenging task. In fact, collusion resistance is regarded as the most relevant requirement of a fingerprinting scheme, and the lack of any acceptable solution to this problem would possibly deter content merchants from deploying any practical implementation of the recombination approach. In this paper, this drawback is overcome by introducing two non-trivial improvements, paving the way for a future real-life application of recombination-based systems. First, Nuida et al.'s collusion-resistant codes are used in segment-wise fashion for the first time. Second, a novel version of the traitor-tracing algorithm is proposed in the encrypted domain, also for the first time, making it possible to provide the buyers with security against framing. In addition, the proposed method avoids the use of public-key cryptography for the multimedia content and expensive cryptographic protocols, leading to excellent performance in terms of both computational and communication burdens. In fact, after bootstrapping, the merchant is no longer required to participate in any file transfer, reducing the investment in equipment required for content distribution to the bare minimum. The paper also analyzes the security and privacy properties of the proposed system both formally and informally, whereas the collusion resistance and the performance of the method are shown by means of experiments and simulations.

Nowadays, many vehicles equipped with RFID-enabled chipsets traverse the Electronic Toll Collection (ETC) systems. Here, we present a scheme to estimate the vehicle cardinality with high accuracy and efficiency. A unique RFID tag is attached to a vehicle, so we identify vehicles through RFID tags. With RFID signal, the location of vehicles can be detected remotely. Our scheme makes the vehicle cardinality estimation based on the location distance of the first vehicle and the second vehicle. Specifically, it derives the relationship between the distance and the number of vehicles. Then, it deduces the optimal parameter settings under certain requirement. According to the actual estimated traffic flow, we put forward a mechanism to improve the estimation efficiency. Conducting extensive experiments, the presented scheme is proven to be outstanding in two aspects. One is the deviation rate of our model is 50% of FNEB algorithm that is the classical scheme. The other is our efficiency is 1.5 times higher than that of FNEB algorithm. Keywords: Vehicle Estimation, VANETs, RFID tag, Privacy Preservation IntroductionThe automobile popularity provides much convenience for people, together with significant serious traffic problems , the traffic manager can evaluate the traffic situation through estimating the number of vehicles and thus make more effective traffic management. Meanwhile, the drivers can access current traffic situation to adjust more effective transportation plan in time.
