Abstract: Embodiments of the present application are an image verification method, a device, a computer apparatus, a storage medium. The method comprises: acquiring a fragment image set formed by segmenting a target image, wherein the fragment image set comprises multiple fragment images; joining, according to a pre-determined restoration rule, the multiple fragment images, and generating the target image; and displaying the target image in a preset verification region, such that a user learns, via the target image, verification information recorded in the target image. The manner of joining to generate the target image from the fragment images is unique, and therefore, if a receiving party does not have a consensus restoration rule with a server, the party will be unable to quickly restore the target image even after obtaining the fragmentation image set or to quickly acquire the verification information recorded therein accordingly. Therefore, the approach of segmenting and transmitting a target image in the invention effectively increases difficulties in cracking image verification, thereby enhancing security of image verification.

Abstract: Disclosed in the present application are a data transmission method and apparatus, for use in improving data transmission performance. A receiving terminal incorporates a blacklist or a blacklist and a whitelist in acknowledgment information transmitted to a transmitting terminal. That is to say, the receiving terminal will promptly notify the transmitting terminal of information on multiple unreceived data packets (e.g., a packet that may cause line header blocking) every time, so that the transmitting terminal can promptly retransmit said data packets to the receiving terminal. In addition, the receiving terminal indicates the whitelist to the transmitting terminal, so that the transmitting terminal can promptly obtain data packets newly received by the receiving terminal, thereby avoiding bandwidth waste at the transmitting terminal caused by invalid retransmission to some extent. During each retransmission, the transmitting terminal will retransmit one retransmission packet for many times, and retransmission times are not consecutive, so that retransmission failure caused by consecutive packet loss is avoided to some extent and thus the retransmission success rate can be improved.
