    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for liveness detection are provided. One of methods includes: displaying an image to a user, and capturing a face image of the user while displaying the image to the user; determining an eye image of an eye of the user based on the face image; extracting a to-be-verified image from the eye image of the user, wherein the to-be-verified image is reflection of the displayed image in the eye of the user; comparing the displayed image with the to-be-verified image to determine whether the to-be-verified image matches the displayed image; and performing liveness detection on the user based on a result of comparison.

    Abstract: Implementations of this disclosure provide data transmission operations and network interface controllers. An example method performed by a first RDMA network interface controller includes obtaining m data packets from a host memory of a first host; sending the m data packets to a second RDMA network interface controller of a second host; backing up the m data packets to a network interface controller memory integrated into the first RDMA network interface controller; determining that the second RDMA network interface controller does not receive n data packets of the m data packets; and in response, obtaining the n data packets from the m data packets that have been backed up to the network interface controller memory integrated into the first RDMA network interface controller, and retransmitting the n data packets to the second RDMA network interface controller.
