Method and system for interactive digital rights management program between different operating system platforms

The present invention relates to a digital rights management, and more particularly to a method and system for a digital rights management program that can be operated between different operating system platforms by using an automatic startup program provided by an operating system, without changing the electronic device. The program or program is added to the electronic device without changing the hardware structure or components of the memory device.

The past digital rights management program was written in a programming language (such as C++) to write a digital rights management program. Since digital rights management involves the underlying structure of an operating system of an electronic player (for example, a mobile phone or a computer) and may call a subroutine specific to the operating system, the digital rights management program will be highly associated with the operating system of the player. Related. This program is then converted to an executable file that can be run on the operating system with the compiler of the operating system.

For example, the digital rights management program written in C++ is converted to a .sis file by the compiler makesis of the mobile device operating system Symbian S60 V3. As a result, the digital rights management program written and compiled will only perform the digital rights management function on the original operating system platform. In addition, the digital rights management program FairPlay compiled with the Apple operating system can only be applied to Apple's computer devices or electronic players (for example, i-Pod), but it cannot perform digital rights management on electronic players using other operating systems. . Similarly, the number of digits compiled by the Windows operating system The rights management program Windows Media DRM is also only available for the Windows family of platforms.

Accordingly, the present invention provides a method and system for a digital rights management program that is interoperable between different operating system platforms.

Based on the above objective, an embodiment of the present invention discloses a method for interactively operating a digital rights management program between different operating system platforms. Encoding and compiling a plurality of rights management programs according to a specific plural operating system, and setting a plurality of directories corresponding to the digital rights management program on a memory device corresponding to one electronic device and a plurality of automatic startup files corresponding to the corresponding directories folder. The digital rights management programs are respectively stored in the corresponding automatic startup folders. When the memory device is inserted into the electronic device, one of the operating systems that automatically activates the electronic device automatically launches a program to select one of the operating systems to automatically launch the folder, and accesses and executes the automatic startup folder for storage. One of the digital rights management programs.

The embodiment of the invention further discloses a system for interactively operating a digital rights management program between different operating system platforms, comprising a memory device and an electronic device. The memory device includes a plurality of directories, wherein each directory includes an auto-launch folder, and each auto-launch folder stores an executable file corresponding to a plurality of rights management programs of the plurality of specific operating systems and a corresponding plurality of package files. The electronic device is equipped with an operating system that provides an automatic start program. When the memory device is inserted into the electronic device, the operating system automatically starts the automatic startup program to select the corresponding One of the operating systems automatically launches the folder and accesses and executes one of the executable files stored in the automatic launch folder and the corresponding plurality of packages.

In order to make the objects, features, and advantages of the present invention more comprehensible, the preferred embodiments of the present invention will be described in detail with reference to Figures 1 through 2 of the drawings. The present specification provides various embodiments to illustrate the technical features of various embodiments of the present invention. The arrangement of the various elements in the embodiments is for illustrative purposes and is not intended to limit the invention. The overlapping portions of the drawings in the embodiments are for the purpose of simplifying the description and are not intended to be related to the different embodiments.

Embodiments of the present invention disclose a method and system for a digital rights management program that can be operated between different operating system platforms by using an automatic startup program provided by an operating system.

The invention utilizes the function of the Auto-Run Function in each operating system, and places the digital rights management subprogram written in various operating system languages in the memory device according to the file name specified by the corresponding automatic startup program. (for example, a memory card) in the folder specified. When a memory device is plugged into a particular electronic player, the operating system on it searches for a particular file in a particular folder (ie, a digital rights management subroutine) and automatically initiates digital rights management. In this way, the digital rights management program can be used across different operating system platforms, overcoming the lack of interoperability problems in the digital rights management program.

Modern electronic player operating systems generally provide the ability to automatically launch programs. When a portable flash memory device (for example, a universal serial stream When the (Universal Serial Bus, USB) flash drive or memory card is inserted into the electronic player, the auto-starter will automatically detect and search for specific format files in a specific directory. If the corresponding auto-start file is found, the operating system starts and executes the file by automatically starting the program. For example, the Symbian S60 V3, the most commonly used operating system on mobile devices, provides a pre-installed application (Preinstalled Applications, PA) that specifies the directory to be \private\10202dce, which automatically launches the program's file. The format is .sis, and the file format of its package file is .pkg. Take Windows Mobile 5.0/6.0/6.1, which is also popular on mobile devices, as an example. The file name and file format of the autostarter is autorun.exe, and this file is stored in the \xxxx directory, where xxxx is electronic. The code for the type of microprocessor of the player. For example, \2577 represents the code of the ARM ARM-1100 processor of the electronic player. If the code of the microprocessor type of the electronic player is not known in advance, the operating system will still look for the \0\autorun.exe executable file in the \0 directory, and then automatically execute the automatic startup file.

Digital rights management of a memory device (eg, memory card) using a programming language (eg, C++) according to a specific operating system (eg, Symbian S60 V3, Windows Mobile 5.0/6.0/6.1..., etc.) The program is encoded (step S11). According to the specific operating system, a directory corresponding to an automatic startup folder (for example, \private\10202dce) is created on the memory device (step S12).

Convert the digital rights management program and name it an executable file (example) For example, .sis). In addition, the corresponding package file (for example, .pkg) of the specific operating system uses a compiler (for example, makesis) corresponding to a specific operating system, wherein the naming and file format of the executable file corresponds to the automatic operation of the specific operating system. The specifications required to start the program (step S13). Therefore, the encoded digital rights management program can only be executed under the specific operating system (for example, Symbian S60 V3, Windows Mobile 5.0/6.0/6.1, etc.). The executable file corresponding to the digital rights management program and the corresponding package file are stored in the corresponding automatic startup folder of the directory (step S14).

Next, it is judged whether or not the encoding of the digital rights management programs of all the specific operating systems to be covered is completed (step S15). If the encoding is not completed, the process returns to step S21, and the above steps are repeated to continue encoding the digital rights management program of another specific operating system until the directories of other automatically launched folders are generated and all the desires are generated on the memory device. The executable file of the operating system is covered.

If the encoding is completed, when the memory device is inserted into the electronic device (step S16), an automatic startup program of one of the operating systems of the electronic device is automatically activated to select one of the operating systems to automatically launch the folder (step S17), and accessing and executing one of the executable files and the corresponding package file stored in the automatic startup folder of the digital rights management program corresponding to the operating system (step S18)
