Publication number: 20240106633Abstract: Embodiments of this specification provide account opening methods, systems, and apparatuses. An example method is performed by a terminal device that includes a trusted execution environment (TEE) and an encryption hardware-based secure element. When it is detected that a current user initiates an account opening request, the terminal device obtains a user public key of the current user in the TEE, and signs a user public key by using a predetermined manufacturer private key, to obtain a user certificate; signs, in the secure element by using a user private key corresponding to the user public key, opening information; generates an opening request in the TEE based on at least the user certificate and signed opening information; and, in the TEE, generates an opening request packet based on the opening request, and sends the opening request packet to a server that opens an account based on the opening request packet.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Applicant: Alipay (Hangzhou) Information Technology Co., Ltd.Inventors: Dengwei Xu, Bingying Zhu, Xianjun Cui, Zhi Xin, Xiaofei Wan, Chao WU

Patent number: 11514605Abstract: Computer automated interactive activity recognition based on keypoint detection includes retrieving, by one or more processors, a temporal sequence of image frames from a video recording. The one or more processors identify first and second keypoints in each of the image frames in the temporal sequence using machine learning techniques. The first keypoints are associated with an object in the temporal sequence of image frames while the second keypoints are associated with an individual interacting with the object. The one or more processors combine the first keypoints with the second keypoints and extract spatial-temporal features from the combination that are used to train a classification model based on which interactive activities can be recognized.Type: GrantFiled: September 29, 2020Date of Patent: November 29, 2022Assignee: International Business Machines CorporationInventors: Dan Zhang, Hong Bing Zhang, Chao Xin, Xue Ping Liu, Zhi Xing Peng, Zhuo Cai
