The data transfer provided by the present disclosure may be to transfer the original file (e.g., doc, pdf, cc, c, etc.),

*.3D, etc.) are transcoded into a gtp file, opened offline, and then rendered as a graphic image, video stream, which renders the graphic image, video information. By the method, the original file can be consulted under the condition that the receiving end does not obtain the original file, so that the receiving end is ensured to obtain correct effective information, and the absolute safety of the original file can be ensured.

The graphics image transmission protocol provided by the present disclosure is used for pixel level acquisition, encoding and decoding, and transmission of images, and therefore, raw data does not need to be transferred, and the format of the raw data is not involved. After the original file is transcoded (duplicated) into an image stream file with a special gtp format, the image stream is opened and viewed when the original file is read, and the mode can ensure the information security of the original file. The process is closed-loop and safe, and can be compatible with original files created by various applications, such as various documents (e.g.,. doc,. xlsx,. ppt,. pdf files) and various image files (e.g.,. 3D,. bmp,. jpeg,.

processing the copied data of the original image according to the operation instruction to obtain an operation result;

and transmitting the operation result to a receiving end in an image stream mode.

In a specific practice, the present disclosure limits user behavior by setting key control information, such as operation time and operation times, during the data copy file exchange process. The values of time and times are set based on the identity level of the recipient and different attributes of the file. After the control information is set, the receiving party can only read the data copy file within a specified time, and the reading times cannot exceed the specified times.

The scheme provided by the disclosure is based on a private image transmission protocol, the original file is subjected to image processing to obtain a data copy file, and the obtained data copy file is used for transmission, so that direct transmission and exchange of the original file are replaced. The mode of presenting the data copy file to the user is image reading, and the mode of opening the file first and then presenting the file in the existing original file transmission process is replaced. The scheme can avoid potential safety hazards in the original file transmission process, and the image transmission process is credible and controllable.

203. The receiving end requests the server to send the original data.

And the receiving terminal requests the server to send the original data according to the target address information.

204. The server verifies the identity information of the receiving end.
