Since its inception, blockchain technology attracts great attention from the industry and academia. With its development, cryptocurrencies such as bitcoin based on blockchain technology gradually emerge and enter the financial field. Meanwhile, malicious behaviors aimed at bitcoin become more and more common and cause huge damage to cryptocurrency users and the evolution of blockchain technology, which prompt researchers to establish various models to deal with this problem. In this paper, we collected the historical bitcoin transaction dataset and extracted features from it. After standardizing features, we used an unsupervised learning model based on Generative Adversarial Networks (GAN) to detect dataset containing more than 30 million normal and 108 malicious samples and reached a precision of 23% and recall value close to 100%.

The existing graph neural network (GNN) systems adopt sample-based training on large-scale graphs over multiple GPUs. Although they support large-scale graph training, large data loading overhead is still a bottleneck. In this work, we propose SCGraph, a method that supports GPU high-speed feature caching. We classify the graph vertices sorted by out-degrees. For high out-degree vertices, we set grading caches via different GPUs to increase the overall cache content through NVLink high-speed data transmission between them. For low out-degree vertices, we expand training vertices’ neighborhood in advance to regenerate cache. We evaluate SCGraph against two state-of-the-art industrial GNN frameworks, i.e., DGL and PaGraph on two datasets Reddit and ogbn-products. Experimental results show that SCGraph achieves up to 1.83× performance speedup over the state-of-the-art baselines.

Load clustering is the early basis of power grid system planning, load modeling, demand side management, load forecasting and other work. The traditional load classification method based on user types can not meet the needs of power grid services. Iterative Self-Organizing Data Analysis Algorithm (ISODATA) is an unsupervised learning dynamic clustering algorithm based on statistical pattern recognition. In view of the current problems that the initial clustering number of each algorithm is difficult to take and easy to fall into local optimum, the principle and implementation steps of ISODATA are introduced, and this algorithm is applied to the power load curve clustering. The clustering analysis is combined with specific power load curve samples, and the results prove that the clustering effect is better and the time improvement is larger. ISODATA is compared with the traditional clustering method to compare the clustering effect and the time loss of the algorithm. The results of the comparison experiments show that ISODATA has good clustering effect when applied to power load curve clustering.Isodata-based clustering of power load curves can fine distinguish users and provide decision support and scientific basis for the reliable operation of power system.

Hepatic fibrosis is an important prognostic factor as severe liver fibrosis may lead to liver cancer or even death. To grade liver fibrosis, ultrasound gray-scale images and ultrasound elastic images are commonly used in clinical diagnosis to judge the severity of liver fibrosis. However, these two diagnoses methods are often vulnerable to disturbances, such as personal experience or instrument differences. Moreover, these individual differences usually lead to conflicting stand-alone machine learning diagnosis models at each hospital whose medical data are not allowed to share in public due to data privacy. To handle the conflicts among diagnosis models, we propose a federated learning based hierarchical diagnosis method of liver fibrosis by utilizing shear wave elasticity pictures of multiple users across hospitals without sharing the original data. Our method is validated with authentic shear wave elasticity pictures of hepatic fibrosis patients in Shanghai, China. Experimental results show that our method is able to preprocess these shear wave elasticity pictures, train local diagnosis models at each hospital and securely consolidate into a shared global diagnosis model whose accuracy is over 70% with only a small dataset containing a few hundreds of labeled pictures. Our method is expected to further improve in its accuracy with more training samples. Our method would be the first practice based on federated learning in liver fibrosis diagnosis.

The HTML5 Web Storage API provides the ability for web applications to store data on client machines. This storage is commonly used for caching, local state tracking, and offline support that allows web applications to work when the web server cannot be contacted. The HTML5 Web Storage is becoming increasingly popular with the majority of new web applications using at least some features provided by this standard. Unfortunately, the local storage provided by HTML5 Web Storage is not entirely secure and does not sufficiently ensure the confidentiality of the user’s data. Encrypting data prior to storage is a common approach to protecting local user data. However, as browser-based applications become more complex and demanding the impact of data encryption may adversely impact application performance. Furthermore, the average web developer is generally not proficient in cryptographic best practices in web applications. First, we provide a simple design approach for encryption of local storage that supports offline web applications. Second, we analyze the impact of various symmetric encryption algorithms and implementations on the performance of the HTML Web Storage API. We show that there are several viable options that will increase the confidentiality and privacy of user data within local storage without imposing significant performance penalties.
HTML5 Web Storage API为Web应用程序提供了在客户机上存储数据的能力。这种存储通常用于缓存、本地状态跟踪和离线支持，允许web应用程序在无法联系web服务器时工作。HTML5 Web Storage正变得越来越流行，因为大多数新的Web应用程序至少使用了这个标准提供的一些特性。不幸的是，HTML5 Web storage提供的本地存储并不完全安全，不能充分保证用户数据的机密性。在存储之前对数据进行加密是保护本地用户数据的常用方法。然而，随着基于浏览器的应用程序变得越来越复杂和苛刻，数据加密的影响可能会对应用程序的性能产生不利影响。此外，一般的web开发人员通常并不精通web应用程序中的加密最佳实践。首先，我们为支持离线web应用程序的本地存储加密提供了一种简单的设计方法。其次，我们分析了各种对称加密算法和实现对HTML Web存储API性能的影响。我们展示了几个可行的选项，可以在不造成显著性能损失的情况下增加本地存储中用户数据的机密性和隐私性。

There are many kinds of energy data, how to realize unified storage, processing and sharing of energy data is a big problem. As the national energy data center, State Grid aims to build a database that can store distributed heterogeneous asynchronous energy data. The storage of image files in the big energy database will take up a lot of space in the system, but not all parts of the image are needed. Therefore, it is very necessary to accurately segment the effective area of the image to store it so as to achieve the purpose of data compression. This paper proposes the Attention U-Net framework, which combines the traditional semantic segmentation network U-Net with the Attention module to focus on the region of interest in the image, emphasize foreground information, and suppress background information. The results show that compared with U-Net, the accuracy is improved by 1.77% and after the segmentation is completed, each image saves an average of 2MB of storage space.

When predicting the total power load of many users, the computing resources often can’t keep up with the growth rate of the total amount of data, and it is difficult to analyze effectively the data in the actual environment. This paper firstly considers clustering users, then predicts each cluster separately, and finally summarizes the results of each cluster to get the result. This paper firstly performs PCA dimension reduction on user data, and then uses the adaptive K-Means clustering method to determine the number of clusters and the initial cluster center, and then uses the determined parameters to cluster the users, and then builds a model for each cluster user and sum up the forecast results to get the total power load. In order to illustrate the effect of this method under different models, this paper establishes XGBoost, CatBoost and LightGBM models respectively and predicts the total power load of all users. From the experimental results, it can be seen that this method is consistent with the actual data trend, and the prediction effect is better than that of directly modeling all user data.

With the rapid growth of the number of mobile devices and the increase of the corresponding computation demand, it has been considered that Mobile Cloud computing and Edge computing will play the significant roles in the upcoming IoT era. It has become an active research topic to develop the offloading schemes for mobile devices, in which the tasks arriving at the mobile devices may be offloaded to run in the cloud or the edge devices. In this paper, mobile edge cloud systems are considered, which consists of mobile devices, edge devices and the cloud server, and the three-tier offloading schemes are proposed to achieve the optimal task performance in MEC. In the three-tier offloading schemes, the computation tasks arriving at the mobile devices may be offloaded to run on the edge devices while the edge devices may further offload the tasks to the cloud when the edge devices are overwhelmed. In this paper, two task modes are considered: batch mode and streaming mode. For the batch mode (i.e., the tasks arriving at the systems and being processed in batches), the offloading optimization problem is modelled as a Mixed 0-1 Integer Programming problem, aiming to minimizing the makespan of the batch of tasks. For streaming mode (i.e., the tasks arriving at the system continuously), the offloading optimization problem is formulated as a non-linear optimization problem, aiming to minimizing the average response time of a task in the task stream. The extensive experiments have been conducted to demonstrate the effectiveness of the proposed offloading schemes, and the impact of various parameters in the MEC systems is also evaluated.

For streaming mode (i.e., the tasks arriving at the system continuously), the offloading optimization problem is formulated as a non-linear optimization problem, aiming to minimizing the average response time of a task in the task stream. The extensive experiments have been conducted to demonstrate the effectiveness of the proposed offloading schemes, and the impact of various parameters in the MEC systems is also evaluated.","PeriodicalId":104366,"journal":{"name":"2022 IEEE 7th International Conference on Smart Cloud (SmartCloud)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130671513","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}
