| Abstract: | File hiding is a key technology in information security field, study on the File hiding technology is valuable to protecting some important files and preventing and killing computer viruses or Trojans. A study on the NTFS volumes and the characteristics of ADS is presented firstly, and a brief introduction of some important meta files on NTFS and some relevant data structures are provided. Based on the study a new type of file hiding method is proposed, and the detailed solutions of specific steps of the method are discussed. This article also illuminates how to extract the hidden files using this method. Using this new method the hidden files have higher concealment and recoverability. |
