The invention discloses a method for realizing secure storage of files, which comprises: acquiring identity information of a file to be written into a storage medium and first information related to the number of idle sectors of the storage medium, and distinguishing the file with other files through the identity information; acquiring a transformed value corresponding to the file by transforming the identify information; processing the first information and the transformed value, and selecting at least one part of sectors from the idle sectors of the storage medium to be actual storage position of the file; and writing the file into the actual storage position. The invention also discloses a device for realizing secure storage of the files and a file reading device. By application of the invention, users can conveniently save and read files required to be kept secret without the necessity of using other passwords or hardware support, and can improve the protection strength of the files and guarantee the security of individual private data which is not required to be shared with other people.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method, a device and a file reading device for realizing safe storage of files. Background technique [0002] The data in the computer is usually stored on disk or other external storage media in the form of files, and the data and attributes contained in general files, such as file name, creation date, file length, and user operation permissions, cannot be changed by copying. Yes, that is to say, the above information is also preserved after the file is copied. Therefore, when a file is copied and stolen, the copied file can be accessed by the thief on various compatible platforms because its data and attributes are exactly the same as the original file. [0003] In the prior art, a method for safe storage and protection of files is to use passwords to protect files. The most commonly used ones are document passwords provided by Microsoft OFFICE. For example, after a user e...
