Abstract: This application discloses a polar code retransmission method and apparatus, to achieve an encoding gain. The method includes: when decoding of the first code word fails, performing polar code encoding on K first to-be-encoded bits and K? second to-be-encoded bits based on a second information bit position set to obtain a second code word, where elements in the second information bit position set are used to indicate positions of the to-be-encoded bits, and an element that is in the second information bit position set and that is used to indicate a position of a first to-be-encoded bit is a sum of N and an element that is in the first information bit position set and that is used to indicate the position of the first to-be-encoded bit; and sending a subcode in the second code word other than the first code word to the decoding device.

Abstract: An identity determination system and an identity determination method are provided. The system includes: a computing node including an image acquisition device, and a server in communication connection with the computing node. The computing node is configured to: collect, by using the image acquisition device, an image according to a preset image collecting frequency; perform face recognition on the collected image to recognize a facial feature in the image; determine node identity information corresponding to the recognized facial feature according to the recognized facial feature; and upload the facial feature and the node identity information corresponding to the facial feature to the server. The server is configured to determine an identity of the facial feature based on the facial feature and the node identity information corresponding to the facial feature uploaded by the computing node.
