Embodiment Construction

[0015] Certain words are used in the specification and subsequent claims to refer to specific elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and the subsequent claims do not use differences in names as a way to distinguish elements, but use differences in functions of elements as a criterion for distinguishing. The "including" mentioned in the entire specification and the subsequent claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupling" here includes any direct and indirect electrical connection means. Therefore, if a first device is described in the text as being coupled to a second device, it means that the first device can be directly electrically connected to the second device. Two devices, or indirectly and electrically connected to the second device through other devices or connecting means.

Abstract

A data accessing system and related storage device. The data accessing system includes a host computer and a storage device. The host computer has a first media access control (MAC) address, and the storage device includes a first storage region, a second storage region, and a controller. The first storage region is utilized for storing data. The second storage region stores a second media access control address. The controller couples to the first storage region and the second storage region for executing a security checking function to determine if the host computer is qualified to access the first storage region according to the first media access control address.

Description

Technical field [0001] The present invention relates to a data storage system and related storage devices, and more particularly to a data storage system and related storage devices that have the function of using hardware to perform security checks. Background technique [0002] In general portable memory devices, such as MMC, CF and other memory cards or other flash memory (Flash memory), it is usually used to conveniently and quickly access data between different hosts. However, in order to prevent a portable memory device from being accidentally lost, the data stored in the portable memory device will be stolen by others. Therefore, in the security field of known portable storage devices, software is usually used to secure the data in the portable storage device. The security method of the software is usually to set a password when the portable storage device is activated and store it in the portable storage device. When the portable storage device is used in the future, the ...
