Abstract: An image processing method for an image, a data transmission method, an image processing device for an image, a data transmission device, and a storage medium are disclosed. The image is a binarized image, and the binarized image includes a plurality of pixels, among the plurality of pixels, pixels having a first value are first pixels, and pixels having a second value are second pixels, and the image processing method includes: dividing the image to determine N rectangular regions, which include only the first pixels, of the image; and obtaining start coordinates and end coordinates of the N rectangular regions, respectively, thereby obtaining compressed data after compressing the image. N is an integer greater than or equal to 1. The image processing method can improve the compression rate of the image.

Abstract: Disclosed are a terminal, a communication system, a communication method and a storage medium. The terminal comprises a receiver and a processor, the receiver is configured to output, upon reception of a destination address in a data packet, a trigger signal; and the processor is configured to control, upon detection of the trigger signal and when the destination address is not the address of the terminal, the receiver to stop receiving the data packet. The present disclosure can effectively reduce power consumption of terminals.

Abstract: The disclosure provides a method, a device and a system for encrypting interactive data. In an aspect, the method includes: receiving a request for accessing a network from a terminal device, the request includes a device identifier of the terminal device; generating a random encryption code according to the device identifier; and feeding back the random encryption code to the terminal device so that the terminal device encrypts interactive data using the random encryption code after accessing the network. In another aspect, the method includes: transmitting a request for accessing a network to a gateway device, the request includes a device identifier of a terminal device; receiving a random encryption code fed back by the gateway device, the random encryption code is information for encrypting interactive data during the terminal device accessing the network; and encrypting interactive data with the random encryption code.
