Description
Technical Field
The invention relates to the field of computer Java application, in particular to a method and a device for protecting the copyright of a Java application file and a mobile terminal.
Background
With the popularization of mobile terminals, mobile value-added services are rapidly developing. Java technology is an open, standard, and universal platform, and is widely favored by operators due to its strong compatibility. Among them, Java Mobile Information Device Profile (MIDP) applications provide support for functions such as user interface, multimedia, game, network connection, etc., for example: support enhanced graphics functions, bluetooth api, support different Hypertext transfer protocol (HTTP) secure connection types, advanced media api and information api, etc. Therefore, the Java MIDP application is widely applied to mobile terminals having a Java 2 platform mini edition (J2ME, Java 2 microeedition) environment.
Currently, there is generally no limitation on the mobile terminal supporting Java MIDP applications in downloading and propagating Java MIDP applications. Fig. 1 is a schematic diagram of a connection between a mobile terminal and a content server, where as shown in fig. 1, mobile terminals a, B, and C are connected to the content server through a network, and the mobile terminals, such as mobile terminal a, mobile terminal B, and mobile terminal C, may mutually transmit and share data files through technologies such as bluetooth and infrared. Typically, when a mobile terminal user discovers a MIDlet (mobile information Devices applet) that he can select for download, the MIDlet can then be downloaded and installed on the mobile terminal for use. The MIDlet is a Java MIDP application running on a mobile terminal supporting the Java MIDP application. As shown in fig. 2, the current process for downloading and installing Java MIDP application generally includes the following steps:
step 201, the mobile terminal starts a browser and is connected to an application server through HTTP;
the mobile terminal user can browse and select and download the Java application files provided by the content server through the application server.
Step 202, a mobile terminal user browses contents provided on a connected application server and selects a Java application file to download;
step 203, the mobile terminal requests to download a Java Application Descriptor (JAD) file of the selected Java Application file;
step 204, after the JAD file is downloaded, the application server informs the mobile terminal;
step 205, an Application Management System (AMS) of the mobile terminal judges whether the downloaded Java application file is Java MIDP application according to JAD file Content Type identification (Content-Type), if so, step 206 is executed; if the application is not Java MIDP application, processing according to a conventional processing flow;
in HTTP, a Multipurpose Internet Mail Extensions (MIME) Type is defined in Content-Type, and MIME is used to set an application program employed to open a file of a certain extension. Therefore, the application program to be used for opening a file with a certain extension can be obtained through the Content-Type, namely, the attribute of the file is obtained through the extension of the file.
Step 206, the browser of the mobile terminal informs the AMS to install the Java MIDP application, and the AMS requests an application server to download a Java Archive (JAR) file;
after receiving the notification of installing the Java MIDP application, the AMS requests the application server to download the JAR file corresponding to the JAD file, and the application server issues a data package related to the Java MIDP application, wherein the data package comprises basic information of the JAR file corresponding to the Java application file, such as the size, Content-Type and the like of the JAR file. Generally, the Content-Type of JAD is the same as the Content-Type of JAR.
Step 207, AMS downloads JAR file corresponding to the Java MIDP application;
step 208, after the JAR file is downloaded, AMS starts to install the corresponding Java MIDP application, namely the JAR file;
and step 209, after the JAR file is installed, returning to the browser interface.
Therefore, through the traditional implementation mode, the mobile terminal can use or propagate the downloaded Java MIDP application without any limitation, namely, a mobile terminal user selects an installed MIDlet to run on the mobile terminal, the mobile terminal can use the installed MIDlet after starting, and is not limited, even the mobile terminal can be propagated to other mobile terminals through some ways, and other mobile terminals can also use the installed MIDP application without limitation, so that the Java MIDP application can be downloaded, used and propagated without control, and the benefit of a Java MIDP application provider cannot be guaranteed.
At present, although there are some methods for protecting the copyright of Java MIDP application, among them, a popular method is to sign a certificate for the Java MIDP application, but if the certificate signing method is adopted, a certificate needs to be installed in advance in a mobile terminal, and the mobile terminal that successfully installs the certificate can still use the Java MIDP application without limit, and the number of times of using the Java MIDP application by the mobile terminal, the service life, and the like cannot be limited.

Detailed Description
The basic idea of the invention is that: when the mobile terminal downloads and installs the Java application file protected by DRM, the AMS and the DRM module carry out mutual information, copyright verification is carried out through the path of the DRM description file of the Java application file, and the path of the DRM description file is stored in the installation process and is used for authentication when the Java application file is operated. Thus, the installation, the use and the propagation of the Java application file can be reasonably limited.
It should be noted that the copyright includes: installing copyright and operating copyright. The installation rights and the running rights may be the same.
Among them, DRM is a business model that controls the use and consumption of contents implemented in content distribution. In mobile download services where content providers and network operators need to control the use and dissemination of downloaded media objects, DRM provides a method of controlling the use of downloaded media objects, that is, DRM allows a content provider to set digital rights to a downloaded media object and allows different rights to be set to the same downloaded media object. The use of downloaded media objects must have corresponding copyright permissions and prohibit illegal copying, but DRM allows legal Distribution of the content that is cryptographically protected by it in a Super Distribution (Super Distribution). Furthermore, the present invention requires that the mobile terminal according to the present invention be able to support DRM.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 3, showing an implementation process of the method for protecting the copyright of the Java application file according to the present invention, this embodiment is a method for providing protection for a download and installation process of a Java MIDP application through DRM, where the Java MIDP application is a Java application file, and this embodiment takes the Java MIDP application as an example to describe the method for protecting the copyright of the Java application file through DRM, and includes the following steps:
after the mobile terminal starts the browser, the mobile terminal is connected to the application server through the HTTP, and a user of the mobile terminal browses the content provided by the application server and selects the Java MIDP application to be downloaded. In this embodiment, the Java MIDP application is packaged as a DRM protected file, that is, a DRM protected Java MIDP application, and the Java MIDP application is DRM packaged by a content server or a content provider. When the Java application file is selected to be downloaded, the user of the mobile terminal can know whether the Java application file selected to be downloaded is DRM protected, but the mobile terminal does not know whether the Java application file selected to be downloaded is DRM protected at this time, but makes a judgment about this in the subsequent steps.
and the browser of the mobile terminal requests an application server to download a JAD file of the selected Java MIDP application, wherein the JAD file comprises the information of the size, the name, the type, the installation path (MIDlet-Jar-URL), the copyright and the like of the Java MIDP application. Here, the copyright includes: install copyright, run copyright, etc.
after the JAD file is downloaded, the browser informs an AMS in the mobile terminal to install the Java MIDP application corresponding to the downloaded JAD file. The mobile terminal downloads a JAR file corresponding to the MIDlet-Jar-URL attribute value according to the MIDlet-Jar-URL attribute value in the JAD file; here, the JAR file is a data file of the Java MIDP application, and therefore, when installing the Java MIDP application, the JAR file corresponding to the Java MIDP application needs to be acquired. In general, JAR files may be used to package secondary resources associated with components, and may also be used to deploy and package libraries, components, plug-ins, and the like. The MIDlet-Jar-URL attribute value in the Java MIDP application specification corresponds to a common JAR file. In this embodiment, the Jar file corresponding to the MIDlet-Jar-URL attribute value includes: an unpackaged normal JAR file and an encrypted packaged JAR file. Here, the unpackaged normal JAR file is an unpackaged Java application file, and the encrypted and packaged JAR file is a DRM-protected Java application file, i.e., a DRM-protected file.
the AMS in the mobile terminal determines whether the JAR file is a DRM protected file by judging whether the Content-Type of the downloaded JAR file is application/vnd.oma.drm.message, and if the Content-Type is application/vnd.oma.drm.message, step 306 is executed; if the Content-Type is not application/vnd. The application/vnd.oma.drm.message is one type of MIME, and when a mobile terminal user requests to download a selected Java MIDP application on an application server, the MIME type of the requested Java MIDP application can be obtained, such as application/vnd.oma.drm.message.
The common JAR file is an unprotected Java MIDP application file, namely a Java MIDP application file without copyright verification, and the mobile terminal does not need to carry out copyright verification operation during downloading and can be directly installed. The step is a conventional processing procedure of the common JAR file, and a downloading procedure of the common JAR file is not described in detail herein.
in the mobile terminal, the AMS calls an interface provided by the DRM module, i.e., a DRM interface, to implement a function of the AMS in interacting information with the DRM module. After judging that the downloaded JAR file is a DRM protected file, the AMS interacts information with the DRM module, performs operations such as copyright verification, plaintext data acquisition, copyright information acquisition and the like on the Java MIDP application, and further realizes the decryption function of the DRM protected file. And, the DRM module creates a DRM description file and a data file, respectively, according to information provided by the AMS, such as copyright information and type of DRM, and data information of the java midp application. Wherein the DRM description file includes: the copyright status of the DRM, the type of the DRM, etc. The data file is data information of JavaMIDP application, such as JAR file. The mobile terminal records the path of the DRM description file and finds the created DRM description file and data file through the path of the DRM description file.
the mobile terminal finds the DRM description file through the path of the DRM description file, and further obtains the installation copyright state of the Java MIDP application recorded in the DRM description file. The installation copyright status includes: installation copyright is valid, installation copyright is invalid, and no copyright is installed, etc.
the AMS of the mobile terminal obtains a data file, such as a JAR file, of the Java MIDP application according to a path of the returned data file, and then installs the Java MIDP application corresponding to the data file. In the process of installing the Java MIDP application, the mobile terminal stores the related information of DRM to the configuration file of the Java MIDP application. Wherein, the related information of DRM includes: DRM type and path of DRM description file, etc.
311, the mobile terminal user runs the installed Java MIDP application, judges the running copyright state according to the related information of DRM in the saved configuration file, if the running copyright is valid, then executes 312; if the running right is temporarily unavailable, go to step 313; if the running right is not valid or is not running, go to step 314;
the mobile terminal can determine the running copyright state according to the related information of the DRM in the saved configuration file, and perform different operations according to different running copyright states, or continue running or resume copyright and the like. The running right may be the same as the installation right of the Java MIDP application requested to run, or may be different from the installation right of the Java MIDP application requested to run, that is, the running right may be set separately.
and the mobile terminal user selects to resume, starts a browser to install the copyright, calls a DRM interface to receive the resumed running copyright, and prompts the mobile terminal user to wait for the arrival of the resumed running copyright by the DRM module. And after the running copyright arrives, returning to step 311, judging the repeated running copyright state, and adopting the corresponding operation according to the repeated running copyright state.
A specific implementation flow for downloading and installing the Java MIDP application is given below, and as shown in fig. 4, the implementation flow includes the following steps:
step 401, the mobile terminal starts a browser and is connected to an application server through HTTP;
step 402, the mobile terminal user browses the content provided by the application server and requests to download a Java MIDP application;
step 403, the browser of the mobile terminal downloads the JAD file corresponding to the requested Java MIDP application;
step 404, after the JAD file is downloaded, the application server informs the browser of the mobile terminal that the JAD file is downloaded;

step 406, according to the MIDlet-Jar-URL attribute value in the JAD file, AMS of the mobile terminal downloads a corresponding JAR file;
step 407, the AMS of the mobile terminal determines the Content-Type of the JAR file, and if the Content-Type is application/vnd.oma.drm.message, the JAR file is protected by DRM, and step 408 is executed; if the Content-Type is not application/vnd.oma.drm.message, the JAR file is not protected by DRM, the JAR file is treated as a common JAR file, and the current flow is ended;
step 408, the AMS of the mobile terminal calls a DRM interface provided by the DRM module to perform information interaction with the DRM module, and the DRM module creates a DRM description file and a data file;
step 409, the DRM module returns the path of the created DRM description file;
step 410, the AMS of the mobile terminal acquires the installation copyright state of the JavaMIDP application according to the path of the returned DRM description file;
step 411, the AMS of the mobile terminal receives the installation right status returned by the DRM module, and determines whether the returned installation right is valid, and if the installation right is valid, performs step 412; if the copyright is not installed or the copyright is not installed, prompting the mobile terminal user that the copyright is not installed, and executing step 415;
step 412, the AMS of the mobile terminal acquires the data file of the Java MIDP application from the DRM module;
step 413, the DRM module of the mobile terminal returns the path of the data file;
step 414, the AMS of the mobile terminal installs the requested Java MIDP application according to the path of the data file returned by the DRM module, and saves the related information of DRM in the configuration file of the Java MIDP application, and then executes step 415;
the AMS of the mobile terminal obtains a data file, such as a JAR file, of the Java MIDP application according to a path of the returned data file, and then installs the Java MIDP application corresponding to the data file. In this process, the AMS of the mobile terminal saves related information of DRM, which includes: the DRM type and the DRM describe the path of the file.
At step 415, the installation process ends and returns to the browser interface.
The first embodiment is an installation process of the Java MIDP application, which needs copyright verification during the installation process, and the path of the DRM description file is saved during the installation process for runtime authentication, so that the installation, the running and the propagation of the Java MIDP application are reasonably limited, and even if the Java MIDP application is sent to another mobile terminal, the Java MIDP application cannot be installed and used due to no copyright. The process by which the mobile terminal user selects to run the Java MIDP application after installation is complete is described below. As shown in fig. 5, a method for protecting Java MIDP application by DRM is shown as an implementation flow of a second method embodiment of the present invention for protecting Java application file copyright, that is, the method includes: the mobile terminal will determine the running copyright state according to the stored related information of DRM, and perform different operations according to different running copyright states, or continue running, or resume copyright, etc., and mainly includes the following steps:
step 501, a mobile terminal user requests to run an installed Java MIDP application;
step 502, AMS judges whether Java MIDP application is protected by DRM, if so, step 503 is executed; and if the Java MIDP application is not protected by DRM, directly running the requested Java MIDP application, and then ending the running process.
And the mobile terminal judges whether the Java MIDP application is protected by DRM according to the DRM type stored in the requested Java MIDP application configuration file.
Step 503, the AMS acquires the running copyright state of the Java MIDP application according to the path of the DRM description file stored in the Java MIDP application configuration file;
the running copyright status includes: the running copyright is valid, the running copyright is temporarily unavailable, and the running copyright is invalid or no running copyright is available, etc.
Step 504, the DRM module returns the running copyright state of the Java MIDP application to the AMS, and takes corresponding operation according to the obtained running copyright state; if the running right is valid, go to step 505; if the running right is temporarily unavailable, go to step 506; if the running copyright is invalid or no running copyright exists, executing step 507;
and 505, the AMS of the mobile terminal starts the requested Java MIDP application and finishes the operation process after finishing the starting.
Step 506, the AMS of the mobile terminal prompts the user of the mobile terminal to use the Java MIDP application later, and the operation flow is ended.
Step 507, the AMS of the mobile terminal prompts the mobile terminal user to resume running the copyright;
step 508, the mobile terminal user selects the running copyright to be resumed, and the mobile terminal starts a browser to download the requested running copyright to be resumed;
and when the browser downloads the running copyright requesting for resuming, the mobile terminal calls the DRM interface to receive the resumed running copyright so as to update the running copyright state information in the DRM description file.
Step 509, the DRM module prompts the mobile terminal user to wait for the running of the rights;
in step 510, the DRM module notifies the AMS that the running rights are reached, and returns to step 502.
For simplicity of explanation, the foregoing embodiments are described as a series of acts or combinations, but it will be appreciated by those skilled in the art that the invention is not limited by the order of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the invention.
