    Anomaly domains detection algorithm based on historical data by Fu-xiang YUAN, Fen-lin LIU, Bin LU, Dao-fu GONG

    Published 2016-10-01
    “…An anomaly domains detection algorithm was proposed based on domains’ historical data.Based on statistical differences in historical data of legitimate domains and malicious domains,the proposed algorithm used domains’ lifetime,changes of whois information,whois information integrity,IP changes,domains that share same IP,TTL value,etc,as main parameters and concrete representations of features for classification were given.And on this basis the proposed algorithm constructed SVM classifier for detecting anomaly domains.Features analysis and experimental results show that the algorithm obtains high detection accuracy to unknown domains,especially suitable for detecting long lived malicious domains.…”

    Phishing detection algorithm based on attention and feature fusion by ZHANG Sirui, YAN Zhiwei, DONG Kejun, YUCHI Xuebiao

    Published 2024-08-01
    “…For instance, current phishing attacks often employ images in place of text and apply small-scale shifts or rotations to high-weight website logo images to evade traditional detection algorithms that rely on text or image features. To address the problem of escalating adversarial phishing technologies, a phishing detection algorithm based on the attention mechanism and feature fusion was proposed, and a hierarchical classification model was established. …”

    Real time interpolation algorithm based on Lanczos kernel by Ying GUO, Lun LI, Peng WANG

    Published 2017-06-01
    “…In order to improve the timeliness and reliability of color image scaling algorithms,a high effective real-time color image scaling algorithm was proposed,which first generated the kernel look up table that could be used for whole target image based on Lanczos kernel,and interpolation of all target image pixels had only fixed point operation which had low computational complexity.Meanwhile,an optimized method for rasterizing pixels of target image was proposed,which needed little memory space but embraced high efficiency of memory utilization.The experiment results show that the proposed algorithm achieves good image quality,and the computational complexity is far more less than classic image scaling algorithms.So the proposed algorithm can effectively implement real-time resizing of color images and color videos in any scaling factors.…”

    Region inpainting algorithm of mouth-muffles for facial recognition by Yue LI, Yaguan QIAN, Xiaohui GUAN, Wei LI, Bin WANG, Zhaoquan GU

    Published 2021-08-01
    “…Facial recognition under occlusion is a well-known difficult problem in real scenes.Especially after the outbreak of COVID-19, in airports, stations and other places that need to verify the identity of visitors, the mouth-muffle occlusion greatly reduces the facial features that can be important for identification, and the accuracy of face recognition algorithm decreases.Face de-occlusion was studied, and a novel framework was proposed to restore face, which used the edge generation network to generate edge maps.On this basis, the occluded region was restored by the region completion network while preserving identity information.In order to improve the performance, the spatial weighted adversarial loss and identity-preserving loss were introduced to train the above two networks.Then two face datasets with mouth-muffles were constructed by face landmarks.The experimental results show that the accuracy of facial recognition algorithm ArcFace on the face dataset restored by the proposed model was 98.39%, which was 4.13% higher than that of directly using ArcFace.…”
