The present specification provides a device comprising: an external device interface unit configured to receive an external input signal including an actual image (an actual picture); a control unit connected to the external device interface unit and configured to detect the external input signal and produce information on the external input signal; an image processing unit connected to the control unit, receiving, from the control unit, at least one among the external input signal and the information on the external input signal, determining an image compressibility on the basis of the information on the external input signal, and outputting a compressed image based on the determined image compressibility; and a communication unit for transmitting the compressed image through a wireless channel.
Abstract: A printing control apparatus that reduces time and effort in security management for printing. The printing control apparatus is configured to communicate with a cloud storage that stores a plurality of print data with different degrees of confidentiality in different storage locations according to the degrees of confidentiality. The printing control apparatus receives a printing instruction and obtains installation location information indicating an installation location of a printing apparatus designated in the printing instruction, and storage location information indicating a storage location of print data designated in the printing instruction. Based on the storage location information and the installation location information, it is determined whether or not printing of the designated print data is allowed. When it is determined that printing of the designated print data is allowed, the designated print data is obtained from the cloud storage, and the obtained print data is printed.
Abstract: A system, method, and computer readable medium for determining authenticity of digital content. The system includes obtaining a video including a plurality of intermediate video frames with respective digital signatures, each video frame of the plurality of intermediate video frames associated with a respective digital signature. The digital signature is generated based at least in part on the image content of the video frame and a hash value of a previous video frame in the same video. Based on using a cryptographic key associated with a recording device used to capture the video, the system can determine authenticity of the content and the ordering of the frames within a video.
