OpenDrift: Online Evolving Fraud Detection for Open-Category and Concept-Drift Transactions

The rapid growth of electronic commerce brings convenience to modern life but comes with security risks by various cybercrimes in online payment services. Most existing security methods for fraud detection depend on the static learning paradigm, which trains a model over a static training dataset and deploys the trained model for inference with the frozen model parameters under the i.i.d. assumption. Unfortunately, this paradigm becomes incommensurate with the increasingly complicated and varying fraud patterns due to the untimely and delayed responses in the offline environment. Without sensing the evolution of fraud timely, it is challenging to train and deploy targeted countermeasures. The emerging means of fraud are not only reflected in the openness of their category, but also in the drift of their superimposed risk features. The interweaving of open-category and concept drift accelerates the process of existing methods becoming powerless. In this paper, we propose EvoFD, an online evolving fraud detection framework to enable continual learning to cope with undercurrent surges of evolving fraud. The core idea of EvoFD is to weaken the bias caused by the anchoring effect on the learned information. It learns in an online streaming fashion by using instructive representations as anchors. Specially, we maintain the progressively updatable class anchors and optimize the representation network to embed features and class anchors into a unified normalized space, where the training and predicting can be conducted simultaneously or independently. In the framework, we preserve the balanced replay memory for each class to accumulate knowledge and avoid forgetting. The advantages of our method are validated by extensive experiments over the real-world dataset from a prestigious bank. © 2023 IEEE.

The password pattern has become a widely used mobile authentication method. However, there are still some potential security problems since the passwords are easy to be cracked by some malicious software. An important research direction of improving its security is adding behavior pattern into the password pattern. The existing methods mainly used user's gesture behavior data such as the location, pressure and contact area of finger collected by touch screen to build a behavior authentication model, which did not consider the influence of user's posture on user's gesture behavior. This paper aims to propose a gesture authentication construction method that is resilient against the change of user's posture. Firstly, for the posture behavior data collected by mobile's orientation sensor and acceleration sensor, we use K-means algorithm to get user's postures. Secondly, we train a gesture authentication sub-model for each posture based on the data collected by touch screen. Finally, we give a behavior authentication method based on these models. Our experimental result shows that the method achieves an effect of 4.36% False Acceptance Rate (FAR) and 5.03% False Rejection Rate (FRR) © 2016 IEEE.

Information-centric networking (ICN) technology is becoming a popular research topic in vehicular networks due to the connectionless and lightweight characteristics of this networking paradigm. Caching plays an essential role in information-centric networks, but current caching techniques for ICN are not ideal for the dynamic and wireless vehicular networks. This paper presents a caching approach for ICN-based vehicular networks that takes into account both the dynamicity of vehicular networks and the popularity of the information being distributed. We introduce an interval metric for selective caching. With this metric and estimates of information popularity and vehicle density, cooperative caching can be realized without exchanging cache management information among the vehicular nodes. Simulation results show that the proposed approach can increase the storage space utilization and has low data response time for vehicular networks. © 2017 Association for computing Machinery.

In this paper, a large-scale human action recognition system is proposed which is built upon the combination of the rising big data processing technology Spark and the powerful Graphics Processing Unit (GPU) in order to fully utilize the efficient in-memory computing ability of Spark and the fine-grained parallel computing capacity of GPU for visual data processing. A number of key algorithms for human action recognition including trajectory based feature extraction, Gaussian Mixture Model (GMM) generation and Fisher Vector (FV) encoding are performed with the proposed GPU-based Spark framework. The experimental results on the benchmark human action dataset Hollywood-2 demonstrate that the proposed GPU-based Spark framework is able to dramatically accelerate the process of human action recognition. © Springer International Publishing AG 2016.

Bibliographical information of scientific papers is of great value since the Science Citation Index is introduced to measure research impact. Most scientific documents available on the web are unstructured or semi-structured, and the automatic reference metadata extraction process becomes an important task. This paper describes a framework for automatic reference metadata extraction from scientific papers. Our system can extract title, author, journal, volume, year, and page from scientific papers in PDF. We utilize a document metadata knowledge base to guide the reference metadata extraction process. The experiment results show that our system achieves a high accuracy.

Computer architectures make a dramatic turn away from improving single-processor performance towards improved parallel performance through integrating many cores in one chip. However, providing directory based coherence protocols for these platforms is too complex and expensive. As a substitute, we propose a synchronization based cache coherence solution, which uses different cache policies according to three flexible software guided scopes (exclusion, producer and consumer scopes) to solve the data-race and coherence problem. Furthermore, this protocol implements word dirty bits (only one bit per word is needed in each L1 cache line) and a special hardware synchronization manager (HSM) to support multi-writer, the write-validate policy and to eliminate the remote un-cache spinning at the "flag". We evaluate Godson-T, a platform supporting this protocol, against an idealized interleaved dual tag directory based protocol on the Splash2 and two bioinformatics benchmarks. The performance of the synch-based protocol is degraded only at 3.2% on average, but the real chip area is reduced at 32% even if the overhead of HSM is included. © 2009 IEEE.

Credit card fraud problem is very common in recent years. It not only causes economic loss to people, but also causes trust crisis to enterprises. Due to the imbalance of data, fraud detection has always been tricky. In our previous work, we proposed a method of dealing with the class imbalance problem based on stacking ensemble learning and inverse random undersampling method (SIRUS). First, the inverse random undersampling method is used to generate multiple data subsets from the original data set. Then we use the stacking ensemble learning method for each data subset to train several different learners (also called first-level learners), and then the results generated by each first-level learner are taken as features to train a meta learner. We apply SIRUS to detect the credit card fraud in this paper. Our dataset comes from a financial company in China. A variety of measurements such as recall, precision, accuracy, F-measure, and G-mean to illustrate the effectiveness of our method in fraud detection. © Springer Nature Switzerland AG 2018.

In deep sub-micron designs, the delay caused by power supply noise (PSN) can no longer be ignored. A PSN-induced path delay fault (PSNPDF) model is proposed in this paper, and should be tested to enhance chip quality. Based on precise timing analysis, we also propose a robust test generation technique for PSNPDF. Concept of timing window is introduced into the PSNPDF model. If two devices in the same feed region simultaneously switch in the same direction, the current waveform of the two devices will have an overlap and excessive PSN will be produced. Experimental results on ISCAS'89 circuits showed test generation can be finished in a few seconds. ©2008 IEEE.

This paper describes the scan test challenges and techniques used in the Godson-3 microprocessor, which is a scalable multicore processor based on the SMOC (Scalable Mesh of Crossbar) on-chip network and targets high-end applications. Advanced techniques are adopted to achieve the scalable, low-power and low-cost scan architecture at the challenge of limited I/O resources and large scale of transistors. To achieve a scalable and flexible test access, a highly elaborate TAM (Test Access Mechanism) is implemented with supporting multiple test instructions and test modes. Taking advantage of multiple cores embedding in the processor, scan partitions are employed to reduce test power and test time, and test compression with more than 10X compression ratio are utilized to decrease the scan chain length. To further decrease test time, a Data-Synchronous-Comparator (DSC) is proposed for comparing the scan responses of the identical cores. © 2009 IEEE.

In grid environment, applications are in active competition with unknown background workloads introduced by other users. To achieve good performance, performance models are used to predict the possible status of the resources, and to make decisions of the selection of a performance-efficient application execution strategy. In this paper, we present a scheduling decision method that utilizes the NARX neural network based load prediction to define data mappings appropriate for dynamic resources. This method uses the information of the predicted CPU load interval and variance of future resource capabilities to obtain the CPU load decision, which can be used to guide the scheduling decision. As to the predictor used here, the NARX neural network based predictor learns the model of the system from the external input information and the system itself. It inherits the mapping capability of feed forward networks and, at the same time, captures the dynamic features of load information. In this work, our predictor shows good performance for time series prediction.
