| Abstract: | Fetion, as an integrated communications service of China Mobile, can PC-To-PC and PC-To-Mobile communication. With the increasing number of China Mobile users, Fetion also has a great number of users too. So it is necessary to research the document transmission of Fetion. Firstly, the process of Fetion document transmission is discussed, then the authors focus on the features of the document transn~ission. By analysis on the plaintext transmission features of mainstream document, such as PDF and DOC file, their transmission features string is obtained. Finally, based on the obtained features string of file transmission, the data recovery of files transferred by Fetion is realized, thus providing a new research idea of certain software for data recovery. |
