The application discloses a method and device for generating initialization parameters, electronic equipment and a computer program product. The method comprises: obtaining a generation instruction of an initialization parameter required for wireless communication, wherein the generation instruction comprises a first instruction for indicating that the initialization parameter is used for generating a reference signal and a second instruction for indicating that the initialization parameter is used for channel data scrambling, and the reference signal is previously agreed by a receiving end and a sending end of the wireless communication; in response to the first instruction, generating a first initialization parameter according to a pre-configured signal integer sequence; and in response to the second instruction, generating a second initialization parameter according to a pre-configured scrambling integer sequence, wherein the scrambling integer sequence is different from the signal integer sequence. The application solves the technical problem of weak security mechanism caused by the fact that the reference signal and data scrambling use the same initialization parameter in the prior art.

This application provides a method for identity verification and authentication of generating events of interest from video streams. The identity verification method includes: extracting and preprocessing frames from the input video stream to remove noise interference and enhance the image quality of keyframes; identifying objects of interest in the video stream using a target detection algorithm and extracting their biometric information; matching the extracted features with a preset identity feature database to determine the object's preliminary identity; verifying the preliminary identity by combining it with scene information of the event of interest, and outputting the identity verification result. The authentication method includes receiving the identity verification result and verifying the accuracy of the identity verification through multimodal feature cross-validation, time series consistency checks, etc., to ensure the reliability of identity recognition in events of interest. The method of this application can effectively improve the reliability of identity recognition for events of interest in video streams and is applicable to various scenarios such as sports videos and intelligent transportation.
