Patent number: 11140197Abstract: Provided are a DDoS attack detection method and apparatus. The method comprises: acquiring network traffic of a target moment within a first period by sampling, then querying a traffic period change curve acquired in advance, determining predicted traffic corresponding to the target moment, and confirming a DDoS attack if the network traffic acquired by sampling is larger than the determined predicted traffic. The traffic period change curve is used for indicating a period change law of the predicted traffic, so that before DDoS attack detection is performed at each target moment, it only needs to determine the predicted traffic corresponding to the target moment according to the traffic period change curve without calculating the predicted traffic according to massive historical traffic data before each DDoS attack detection; and the calculation volume is reduced.Type: GrantFiled: February 22, 2017Date of Patent: October 5, 2021Assignee: NSFOCUS INFORMATION TECHNOLOGY CO., LTD.Inventors: Hanbing Chen, Bin Zheng, Kun He

Patent number: 10997746Abstract: Feature descriptor matching described herein may include receiving a first input image and a second input image. A feature detector may detect features from the first and second input images. A descriptor extractor may learn local feature descriptors from the features of the first and second input images based on a feature descriptor matching model trained using a ground truth data set. The descriptor extractor may determine a listwise mean average precision (mAP) rank of a pool of candidate image patches from the second input image with respect to a queried image patch from the first input image based on the feature descriptor matching model, the first set of local feature descriptors, and the second set of local feature descriptors. The descriptor matcher may generate a geometric transformation between the first input image and the second input image based on the listwise mAP and a convolutional neural network.Type: GrantFiled: April 11, 2019Date of Patent: May 4, 2021Assignee: Honda Motor Co., Ltd.Inventors: Kun He, Yan Lu

Patent number: 10990626Abstract: A data storage and retrieval system employs online supervised hashing for indexing a data set and retrieving data items therefrom. A hash-based mapping is used to generate hash codes for indexing content items. Data items may be retrieved based on either/both a query label (using corresponding codewords) and the content item itself (using the hash codes). The hash-based mapping is updated using an objective function of distance between the hash codes and respective codewords for labels of labelled content items, preserving semantic similarities of content items. The codewords may be error-correcting codes. Techniques for efficiently updating the index include (1) cycle-based updating and ternary codewords, and (2) reservoir sample-based method of determining when to trigger an update.Type: GrantFiled: September 23, 2016Date of Patent: April 27, 2021Assignee: Trustees of Boston UniversityInventors: Stanley Sclaroff, Fatih Cakir, Kun He
