  • Publication number: 20220277596
    Abstract: This application discloses a face anti-spoofing recognition method and apparatus, a device, and a storage medium, and relates to the field of artificial intelligence (AI) technologies. The method is performed by a computer device, including: acquiring face video data including a to-be-detected face; detecting eye contours of the to-be-detected face from image frames of the face video data, and generating an eye contour sequence; performing eye movement probability prediction based on the eye contour sequence, and generating an eye movement state sequence; acquiring a first dataset and a second dataset in the eye movement state sequence; determining a probability of existence of an abnormal blink behavior of the to-be-detected face according to the first dataset and the second dataset; and determining that the to-be-detected face is a real face in a case that the probability is less than a predetermined threshold.

  • Publication number: 20220145356
    Abstract: The present invention discloses a swab sample nucleic acid releaser and use thereof. The sample releaser includes 1-20 mol/L of a metal ion chelating agent, 5-80 mmol/L of a buffer at pH 6-9, 5%-40% (v/v) of a polar organic solvent, 0.2%-10% (v/v) of a surfactant, and 0.1-1 mol/L of a nuclease inhibitor. The sample releaser can integrate three steps of sampling and preservation, inactivation, and nucleic acid extraction into one step, and after sampling, the sample can be directly put into a sampling tube equipped with the sample releaser for storage and transportation; and when in use, the sampling tube is turned upside down and mixed well, and after the sample and the sample releaser are fully mixed, it is let stand for a few minutes at room temperature to release the nucleic acid of the sample.

  • Patent number: 10176323
    Abstract: The present application discloses a method, an apparatus and a terminal for detecting a malware file. One embodiment of the method comprises: obtaining a file to be inspected; determining an entropy vector of the file; and inspecting the entropy vector of the file using a trained inspection model to determine if the file is a malware file, wherein a file type of the file is identical to the file type corresponding to the inspection model. This embodiment extracts the entropy vector of the file and determines if the file is a malware file based on the entropy vector of the file. Therefore, the technical problems existed in the art, such as a low speed, a poor capacity and a low efficiency of detecting and destroying the malware file, are addressed and the efficiency of detecting and destroying the malware file is enhanced.

  • Publication number: 20150143523
    Abstract: Embodiments of the present disclosure provide a virus processing method and apparatus. In embodiments of the present disclosure, attribute analysis on the threads contained in the target process is performed to determine whether at least one of the threads contained in the target process matches virus attribute information. If at least one of the threads contained in the target process matches virus attribute information, virus type information is determined based on the matched virus attribute information, so that execution of process creation operation is prohibited based on the virus type information. Due to the measures of prohibiting execution of process creation operation, replication of virus in the system can be effectively prevented so as to improve security performance of the system.
