Embodiment Construction

[0047] First, see figure 2 , which is a schematic diagram of the system architecture of the pairing encryption system 2 of the present invention. Such as figure 2 As shown, the pair encryption system 2 includes a storage device 20 , a host 22 and a pair encryption device 24 . The storage device 20 stores confidential data and is configured to be paired with the host 22 . The purpose of this pairing is to limit the use authority of the confidential data of the storage device 20 , and the client can only access the confidential data of the storage device 20 through the host 22 . The host 22 here is an electronic product, such as a personal digital assistant, a wireless communication device, a digital camera, a digital video player, and a GPS navigation system. The storage device 20 refers to a large-capacity storage medium, including flash memory cards of various specifications. The storage device 20 is pluggably connected to the host 22 , and the host 22 accesses and uses t...

Abstract

The invention relates to a security method for controlling the access of host on memory device, wherein the memory device comprises a memory storing a first recognition code and a file system, the structure of the file system is matched to store secure data and a first memory space. The host pre-stores a second recognition code. The inventive security method comprises sending the data of the first memory space to the host, while the first memory space is generated by match security program, decrypting the data in the first memory space to generate a decrypt data, judging the correct of the decrypt data that checks if the decrypt data meets the first recognition code and security data, referring the correct of the decrypt data, controlling the host to store the security data. The invention can improve the security of storing device to provide more security to data supplier and client.

Description

technical field [0001] The present invention relates to a security method and system, in particular to a data security method and system, and a paired encryption system of a storage device and a host computer. Background technique [0002] The functions of consumer electronic products are becoming more and more diversified, and the user's demand for large-capacity data storage is also increasing. Therefore, it has become a trend to support expansion of storage capacity by inserting storage devices such as compact flash cards (for example, storage cards including Multimedia cards, Memorystick cards, etc.). If the data in digital format stored in the storage device is confidential or subject to copyright protection, the access authority of the end user must be restricted through a security procedure to prevent the digital data from being copied and distributed at will. [0003] Here, a method of securing data in a digital format will be briefly described. see figure 1 , whi...
