Embodiment Construction

[0041] What is described in this chapter is the best way to implement the present invention. The purpose is to illustrate the spirit of the present invention rather than to limit the protection scope of the present invention. .

[0042] figure 1 It is a block diagram showing a secure portable medium 100 according to an embodiment of the present invention, wherein the secure portable medium 100 can be used to store secure data. In one embodiment, the secure portable medium 100 includes a controller 102 and a non-volatile memory 104 . The secure portable medium 100 can be a Secure Digital card (Secure Digital card, SD card), a Multi-Media Card (Multi-Media Card, MMC) or a Universal Serial Bus (USB) flash drive. The non-volatile memory 104 has a Unique Identity (UID) of the media ID, and thus the secure portable media 100 can be identified according to the UID generated by the firmware 132 . The media identification code UID is physically engraved on the semiconductor chip of ...

Abstract

The invention provides a secure removable media. In one embodiment, the secure removable media comprises a non-volatile memory, a controller and a security program. The non-volatile memory corresponds to a media identifying code, and comprises a public area, a bidden area, and a reserved hidden area for data storage, wherein a first firmware for retrieving the media identifying code and a second firmware for accessing the hidden area are stored in the reserved hidden area, and the media identifying code is engraved on a semiconductor chip of the non-volatile memory physically and is not stored in a normal memory unit. The controller receives secure data from an external device. The security program is stored in the public area, uses the first firmware to retrieve the media identifying code from the secure removable media, generates an encryption key according to the media identifier given by the first firmware, encrypt the secure data according to the encryption key to obtain an encrypted secure data, and uses the second firmware to write the encrypted secure data to the hidden area.

Description

technical field [0001] The present invention is primarily concerned with data access, and more particularly with secure data access. Background technique [0002] Digital Rights Management (DRM) is a technology used to protect digital data in access control. Hardware manufacturers, publishers, and rights owners use this technology to protect the content of digital data. Digital rights management technology protects and controls the use of digital media by preventing unauthorized access, copying and transfer operations from users. Digital rights management technology has been used in the products of many companies, such as SONY, Amazon, Apple, Microsoft, etc. [0003] When a user end wants to play a digital content, the user end downloads the digital content to a client-end device from a DRM server, and the DRM server issues a rights object to the client device. The user terminal can play the digital content stored in the client device according to the rights object. If th...
