Abstract:
Digital content delivery system and method are provided. The system includes a central management system and a delivery machine coupled to the central management system via a network. The delivery machine includes a storage unit including a plurality of DRM (Digital Rights Management) contents, a user interface, and a connection interface. The delivery machine receives a selection of at least one of the DRM contents via the user interface, and transmits order information corresponding to the selection of the selected DRM content to the central management system via the network. The central management system generates a rights object for the selected DRM content according to the order information, and transmits the rights object to the delivery machine. The delivery machine transmits the selected DRM content and the rights object to a storage device via the connection interface.
Abstract:
A method for fabricating a magnetic tunnel junction cell includes steps of providing a substrate having an active surface, forming a tunnel layer, a fixed layer and a first electrode, forming a U-shaped free layer having a vertical portion substantially perpendicular to the active surface, and forming a second electrode embedded in the U-shaped free layer. The fixed layer lines an inner surface of a through hole substantially perpendicular to the active surface and the first electrode fills the through hole. The tunnel layer may line the inner surface of the through hole or be U-shaped lining an inner surface of the U-shaped free layer. The fixed layer, the tunnel layer and the U-shaped free layer constitute a magnetic tunnel junction.
Abstract:
An OA device for preloading content on memory cards is disclosed. A handler control module of a control unit performs a preloading process which comprises a preload check, preloading content based on digital content stored in buffers, and a preloaded content comparison, wherein memory cards at the initial column of a tray are checked, preloaded, and compared with the preloaded digital content using probes of a probe module. When the preloading content for the memory cards at the initial column of the tray is complete, the tray module or the probe module is moved by a stepper module by a predetermined distance, or the moving arm moves the probe module with a predetermined distance, to enable the memory cards at the next column of the tray to be checked, preloaded, and compared with the preloaded digital content using the probes while a sorting module picks up failed memory cards from the previous column based on records and instructions from the handler control module of the control unit.
Abstract:
Storage device management systems and methods are provided. The system includes a storage device and an electronic device. The storage device has a UID, and a public area including a plurality of zones. Each zone includes an interpretation module. The electronic device selects one of the zones, reads the interpretation module from the selected zone of the storage device, and executes the interpretation module to read the UID, and interpret the UID as a specific UID. The electronic device manages the storage device locally or remotely based on the specific UID.
Abstract:
Systems and methods for managing storage devices are provided. The system includes a storage device having at least one hidden area. The hidden area is created using initialization firmware, and the hidden area is allowed to be accessed by using a library. A password authentication mechanism is applied to the hidden area of the storage device. When an input password received via a specific application conforms to a predefined password of the hidden area, the hidden area is allowed to be accessed by using the library. Since the storage device may have a plurality of hidden areas, and each hidden area may have a respective password, the respective hidden areas can be independently and securely managed. Additionally, since the predefined password can be changed by a purchasing company, the manufacturer of the storage device or the microcontroller company which designed the microcontroller of the storage device is prohibited from accessing the hidden area by any means after the predefined password of the hidden area is changed by the purchasing company.
Abstract:
A method for enhancing data encryption using multiple-key lists is disclosed. A first multiple-key list and a second multiple-key list for a decryption key are created, wherein each multiple-key list comprises plural partial decryption keys. Content to be accessed is encrypted using an encryption key corresponding to the decryption key. The first multiple-key list is stored in a hidden area of a memory device storing the content. The second multiple-key list is stored in the memory device. When the memory device is installed on an electronic device, an application installed in the electronic device is activated to select a first partial decryption key from the first multiple-key list stored in the hidden area and a second partial decryption key from the memory device, re-organizes and codes the first and second partial decryption keys to recover the decryption key, and decrypts the content using the decryption key, enabling the electronic device to access the content.
Abstract:
Systems and methods for locally generating a license and activating a Digital Rights Management (DRM) agent are provided. The system includes a storage device and an electronic device. The storage device includes a DRM treated file, operation information, and a management application. The electronic device activates the management application from the storage device to retrieve information, such as a Unique Identification (UID) or a DRM machine certificate from the electronic device, and generate a license for the electronic device according to the operation information, and the retrieved information of the electronic device. The electronic device activates a DRM agent by providing the DRM treated file and the license to the DRM agent for playing back the DRM treated file based on the license. The management application may set the license expired after the DRM treated file is played back on the electronic device.
Abstract:
A method for locally activating a DRM engine is disclosed. A preprocessing operation is performed, wherein rights objects are bound with digital content files with a first format. The digital content files with the first format are converted to the digital content files with a second format. The digital content files with the second format file are encrypted and a corresponding decryption key is generated. The encrypted digital content files and the decryption key are stored in a memory device. An application is designed and installed on the electronic device and the memory device is installed to the electronic device. The application is authorized according to the rights objects bound in the digital content files, decrypts the encrypted digital content files using the decryption key, wherein the digital content files with the second format can be recovered from the third format, and activates a DRM engine of the electronic device. The DRM engine binds an IMEI code of the electronic device with the digital content files, enabling the digital content files to only be accessed by the specific electronic device.

Abstract:
A method for hiding the decryption key in a dispersive way is disclosed. A decryption key corresponding to content to be accessed is decomposed into at least two partial decryption keys, comprising first partial decryption key and second partial decryption key. The first partial decryption key is stored in a memory device. The second partial decryption key is stored in a hidden area of the memory device. When the memory device is installed on an electronic device, an application installed in the electronic device is activated. The application retrieves the first partial decryption key from the memory device and the second partial decryption key from the hidden area of the memory device, re-organizes and codes the first and second partial decryption keys to recover the decryption key, and decrypts the content using the decryption key, enabling the electronic device to access the content.
