Dynamic privacy measurement model and evaluation system for mobile edge crowdsensing by Mingfeng ZHAO, Chen LEI, Yang ZHONG, Jinbo XIONG

“…To tackle the problems of users not having intuitive cognition of the dynamic privacy changes contained in their sensing data in mobile edge crowdsensing (MECS) and lack of personalized privacy risk warning values in the data uploading stage, a dynamic privacy measurement (DPM) model was proposed.A structured representation of data obtained by a user participating in a sensing task was introduced and was transformed it into a numerical matrix.Then privacy attribute preference and timeliness were presented to quantify the dynamic privacy changes of data.With this, personalized privacy thresholds of users based on the numerical matrix were reasonably calculated.Finally, differential privacy processing was performed on the numerical matrix, and a model evaluation system was designed for the proposed model.The simulation results show that the DPM model was effective and practical.According to the given example, a data utility of approximately 0.7 can be achieved, and the degree of privacy protection can be significantly improved as the noise level increases, adapting to the MECS of IoT.…”

Building method of distributed COW disk on network computing environment by Huai-liang TAN, Zheng LUO, Zai-hong HE, Ren-fa LI

“…Aiming to distributed computing and data centralizing storage in large-scale network computing environments and combining sparse and bursting characteristic of COW(copy-on-write) disk storing modified data blocks,the distributed COW network disk architecture was presented.The system building process of network computing environments was speeded up by apportioning the aggregation spending that server manages all related COW disks of client hosts to each client host.A improving 64bit bitmap compress arithmetic was designed to reduce the size of COW disk’s bitmap,so server disk space was saved and the network communication spending of distributed COW disk was less.The modified prefetching arithmetic based on COW bursting blocks was presented to improve the hit rate of Cache relating with distributed COW disk.Experiments on the prototype show that the distributed COW mechanism can effectively reduce system building latency of multi-client hosts network computing environment based on improving COW bitmap compress and prefetching arithmetic.…”

Research on optimal channel access method for distributed wireless network based on reliable multicast communication by Yizhu WANG, Zhou ZHANG, Piming MA, Baoquan REN

“…To address the low spectrum utilization issue of the distributed network due to multi-user collision and channel time-varying nature, the distributed channel access problem for multicast communication was investigated.Based on the optimal stopping theory, a statistical model of distributed channel access under wireless multicasts was established, and an optimal distributed wireless channel access method under reliable multicast communication was proposed.Each source competes for the channel in a distributed manner, the winner source determines whether to access the shared channel by comparing the reliable multicast access rate with a pure threshold to complete the reliable multicast communication from the winner source to all the sinks.Theoretic optimality of the method was proved rigorously.A corresponding low-complexity algorithm was designed, which has a pure threshold structure and good engineering practicability.Numerical results show that the proposed channel access method can effectively improve the average throughput of the system.…”

SQLMVED: SQL injection runtime prevention system based on multi-variant execution by Bolin MA, Zheng ZHANG, Hao LIU, Jiangxing WU

“…The effectiveness of combining SQL statement parsing with randomization to defend against SQL injection attack (SQLIA) was based on the fact that attackers did not know about the current method of randomization adopted by system.Therefore, once attackers had mastered the current method of randomization who can launch effective SQLIA.In order to solve this problem, a SQL injection runtime prevention system based on multi-variant execution was designed, the multi-variant apply randomization methods from any other, so that illegal SQL statements could not be parsed successfully by all variants.Even if attackers had mastered the method of randomization, illegal SQL statements could only be parsed successfully by a certain variant at most, meanwhile the parsing results of multiple variants were voted to find the abnormality in time and block attack path.The prototype system SQLMVED is implemented for Web services and experiments show that the prototype can effectively defeat SQLIA.…”

Compact RFID tag antenna based on square spiral resonator by Libin DAI, Zhimeng XU, Jiade YUAN

“…A miniaturized ultra-high frequency (UHF) radio frequency identification (RFID) tag antenna was designed.The antenna was composed of two square spiral resonators shorted inside and outside.By adjusting the edge length of the outer ring spiral resonator and the spacing between the inner and outer ring spiral resonators, the resonant frequency of the proposed tag antenna could be effectively tuned.The simulation results show that the proposed tag antenna has good impedance matching and the frequency band range covers the whole UHF band (840～960 MHz).It has a dimension of 7.60 mm×7.60 mm×0.05 mm, which is 96% smaller than the traditional spiral resonator (SR) antenna.The measure result shows that the proposed tag antenna achieves the maximum reading distance at 910 MHz in 4 W effective isotropic radiated power.The proposed UHF RFID tag antenna has some advantages of small size, wide frequency band, low cost and easy batch fabrication, and is suitable for applications with small size requirements.…”
