Multi-camera video collaborative analysis method based on edge computing by Zhibo QI, Lei DU, Ru HUO, Fan YANG, Tao HUANG

“…In order to reduce the processing volume of multi-camera real-time video data in smart city scenarios, a video collaborative analysis method based on machine learning algorithms at the edge was proposed.Firstly, for the important objects detected by each camera, different key windows were designed to filter the region of interest (RoI) in the video, reduce the video data volume and extract its features.Then, based on the extracted data features, the same objects in the videos from different cameras were annotated, and a strategy for calculating the association degree value between cameras was designed for further reducing the video data volume.Finally, the GC-ReID algorithm based on graph convolutional network (GCN) and re-identification (ReID) was proposed, aiming at achieving the collaborative analysis of multi-camera videos.The experimental results show that proposed method can effectively reduce the system latency and improve the video compression rate while ensuring the high accuracy, compared with the existing video analysis methods.…”

Game theory based forwarding control method for social network by Fangfang SHAN, Hui LI, Hui ZHU

“…With the rapid development of mobile communication and internet technology,the social network has become one of the mainstream social means used in people’s daily social life.To maintain and strengthen relationships with friends,users may share personal behavior and feelings through social networks.Forwarding these contents may result in privacy leakage.To help publishers make proper data forwarding decision,the benefits of both sides of the forwarding operation were analyzed,and a game theory based forwarding control method for social network was proposed which could effectively prevent dishonest data forwarding operation.By analyzing the benefits of both sides of forwarding operation and considering historical information,the probability of dishonest data forwarding operation was calculated and it was compared with the threshold set by publisher to make the forwarding decision.The procedure and framework of the game theory based forwarding control method was introduced.The benefits of both sides were defined and analyzed.The game play scenario was presented.Some results of experiments are shown to support that the method is effective and it can protect the security of content in social network.…”

Failure recovery algorithm for LRT and transaction property analysis by Xiao-yong MEI, Chang-qin HUANG, Xiao-lin ZHENG, De-ren CHEN, Shi-xian LI

“…Researchers have worked on recovery strategies of composition transactions,most efforts focus on transaction consistency by backward recovery,compensation is commonly used for backward recovery,which have limitations since the cost of compensation tasks are rather expensive,and the compensation mechanism can not satisfy various requirements of applications.A transaction recovery algorithm was proposed including forward recovery,backward recovery and alternative recovery,which was a formal modeling method based on extended Petri nets,state token，data token and QoS token were introduced to implement relaxed ACID properties of LRT.When failure occurs,terminate dependency point (TDP) and compensation set were calculated dynamically,recovery strategies were added or deleted automatically according to the data flow dependency,control flow dependency and state dependency among tasks.Failure types are generated by log file mining,therefore,failure coordination and recovery are implemented and an executable model which support add/delete failure recovery behavior is constructed seamlessly.…”

THE DETERMINNATION OF RESIDUAL STRESS OF GEAR TOOTH ROOT BASED ON X-RAY TECHNOLOGY by WANG Zhen, HU TianTong, FENG XianZhang, MENG XiangZhi

“…Transverse residual stress of tooth root has significant influence on bending fatigue strength of gears.But given the geometry of gears,using the method of exposing teeth root to complete determination of transverse residual stress at present,it not only destroys the original stress state of material surface,but conflicts with the concept of residual stress measurement by Xray nondestructive.so in order to do not cut gears,which can also more accurately measure transverse residual stress of the gear tooth root,in this paper,through combining with the theoretical analysis and experimental verification method,the relationship of transverse and longitudinal residual stress of the gear tooth root is derived.With the known of Bragg Angle of free stress— θ₀,the transverse residual stress of Gear tooth root can be calculated by the size of the longitudinal residual stress through the X-ray method measured,so it is convenient to measure the transverse residual stress of gear tooth root.…”

Analysis model of binary code security flaws based on structure characteristics by Tuan XU, Lei-lei QU, Wen-chang SHI

“…Aiming at the shortcomings of the existing methods to detect the security flaws that have complex structures,a new analysis model and its application method was proposed.First,analysis models based on key information of code structures extracted from path subsets of characteristic element sets that are generated by source code element sets of code security flaws were constructed.Then the analysis model according to the statistical probability of each kind of IR statement was calculated,and the IR code group which matched the feature model was found.Finally,through the translating relation between binary codes and IR codes,various code security flaws of binary program were found out.The analysis models can be applied to both common single-process binary programs and binary parallel programs.Experimental results show that compared with the existing methods,the application of the analysis model can be more comprehensive and in-depth in detecting various types of complex binary code security flaws with higher accuracy.…”

“…Aiming at the problems of data leakage of perceptual image and computational inefficiency of privacy-preserving classification framework in edge-side computing environment, a lightweight and privacy-preserving classification framework (PPCF) was proposed to supports encryption feature extraction and classification, and achieve the goal of data transmission and computing security under the collaborative classification process of edge nodes.Firstly, a series of secure computing protocols were designed based on additive secret sharing.Furthermore, two non-collusive edge servers were used to perform secure convolution, secure batch normalization, secure activation, secure pooling and other deep neural network computing layers to realize PPCF.Theoretical and security analysis indicate that PPCF has excellent accuracy and proved to be security.Actual performance evaluation show that PPCF can achieve the same classification accuracy as plaintext environment.At the same time, compared with homomorphic encryption and multi-round iterative calculation schemes, PPCF has obvious advantages in terms of computational cost and communication overhead.…”
