However, most existing methods only focus on one aspect of network either network structure or node attributes, ignoring the interaction between network structure and node attributes. Meanwhile, they regard reconstruction error as node anomaly score, which lacks considering the other factors for computing score. Therefore, in this paper, we propose a method for attributed network anomaly detection based on an autoencoder considering the node attention mechanism and an anomaly score generator. The autoencoder considers not only network structure but also node attributes to obtain a higher-quality embedded representation. Meanwhile, the decoder reconstructs the adjacency matrix and calculates the reconstruction error. The anomaly score generator uses a multi-layer perceptron (MLP) as the basic framework. In addition, in order to better consider the calculation of the node anomaly score by the reconstruction error, we concatenate the reconstruction error, reconstruct the residual direction vector and embedding vector to construct input vector for training MLP. At last, the final output is node anomaly score, and anomaly detection achieved. Experiments on three real-world datasets prove the effectiveness of our method.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123046440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, at the same time, the security and safety defenders have noticed that it is more and more difficult to prevent people from photographing the contents on the screens, especially when the photographic equipment is undergoing miniaturization and intelligentization, and that promotes the information and privacy leakage inevitably. There are plenty of technical solutions that have been proposed previously, but few of the exiting schemes are feasible for daily and widespread applications because most of them require some additional and customized hardware to be mounted on the screens or audiences. Therefore, in this paper, we propose an intelligent content protection scheme for videos on screens, which is designed to prevent audiences from photographing the entire picture of the screen while having no observable influence for direct observation with naked eyes. Furthermore, our experiments demonstrate that, for the 1080P and 60 fps videos on ordinary LCD screens, our scheme outperforms the existing schemes in terms of occlusion rate, effective distance and so on.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115986952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AFL (American Fuzzy Lop) is a mutation-based fuzzing technology, and it is also one of the most popular and effective fuzzing tools. It has good performance and performance in mining vulnerabilities. Aiming at network applications and based on AFL, this paper optimizes the framework’s deficiencies in seed generation and seed selection, and designs and implements a higher-performance vulnerability detection tool. In the aspect of seed generation, the PSO (particle swarm optimization) algorithm is used to modify some related algorithms in the mutation stage of AFL to optimize the operator selection process in this stage. Instead of using the fixed selection algorithm, the current operator environment and the previous operator environment are considered in each operator selection to make a decision. In the aspect of seed selection, we model the number of mutation times needed by the seeds to generate new paths, give priority to the seeds that execute low-frequency paths, and give them higher mutation times, that is, the power of the seeds, so as to improve the utilization efficiency of the seeds and obtain more path coverage.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127255217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing studies aim to train an accurate prediction model by extracting different features, however, few of them systematically investigate the power of features from different domains when they are used separately or jointly. To this end, we conduct a comparative study on multi-domain feature extraction for human activity recognition. Specifically, we first extract features from the time-, frequency-, and wavelet-domains, and then use different combinations of the three domain features to build activity recognizers. Finally, comparative experiments are performed on two activity recognition datasets and four classification models are used to avoid selection bias. Results indicate the superiority of using time-domain or frequency-domain features over wavelet features in terms of prediction performance and also show that the simultaneous use of multi-domain features generally generalizes better across datasets and classifiers, indicating that they, to a certain extent, contain complementary feature information.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122098996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can provide more flexible LBS proximity detection query, which has attracted widespread attention in recent years. However, the development of proximity detection query still faces many severe challenges including query information privacy. For example, when users want to ensure their location privacy and data security, they can get more secure location-based services. In this article, we propose an efficient and privacy-protecting proximity detection framework based on location services: PD(Proximity Detection). Through PD, users can query the range of arbitrary polygons and obtain accurate LBS results. Specifically, based on homomorphic encryption technology, an efficient PRQ(polygon range query) algorithm is constructed. With the help of PRQ, PD, you can obtain accurate polygon range query results through the encryption request and the services provided by the LAS(LBS Agent Server) and the CS(Cloud Server). In addition, the query privacy of the queryer and the information of the data provider are protected. The correctness proof and performance analysis show that the scheme is safe and feasible. Therefore, our scheme is suitable for many practical applications.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134083552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
