Structure for enciphering data by memory region

Abstract

A data component using memory block to carry out data-enciphering consists of a reserving sector, double file configuring table for utilizing an enciphering method to encipher registration item of each file configuration table and its corresponding cluster set as well as hiding enciphered index file in a preserved item, radical catalogue for clearing off file registration item of original data, data region for storing file registration item and file configuration table registration item with its corresponding cluster as per storage path of index file, master activation sector for storing an enciphering record of said enciphering method.

Description

technical field [0001] The invention relates to a data structure for encrypting data, in particular to a data structure for encrypting data through a memory block. Background technique [0002] Generally, the data arrangement of plug-and-play storage devices (such as SD cards) has a standard format, so the data can be read out under different brands of card reader equipment, because of the small size of plug-and-play storage devices and the Because of its convenience, it is often used as a storage medium in private small electronic products, such as mobile phones, PDAs, digital cameras, etc. However, since these electronic products are often used to store private data, when these data are stored in plug-and-play storage devices However, it is accidentally lost or stolen by others, and the data in it can be easily read by anyone with a card reading device. Therefore, although the plug-and-play storage device is convenient, the result of standardization makes personal private ...
