Abstract

This invention disclosed a data structure using memory blocks to encrypt data. The structure comprises at least one reserved sector and a dual-file arrangement table. One encrypting method is used to encrypt every registered item in the file arrangement table and the relative clusters. An encrypted index file then is hidden in a reserved item. In a root directory, the registered item of the file of original data is deleted. In a data area, the registered item of a file, the registered item of a file arrangement table, and the relative clusters are saved according to the saved path of an index file. A master boot sector can be used to save an encryption record that is coded by an encrypting method.
