Embodiment Construction

[0031] In the following, the mobile phone is used as an example of a mobile information terminal, and the installation method is through the serial port of the mobile phone as an example to expand the description.

[0032] The mobile phone implementing the method of the present invention should be a mobile phone with larger storage capacity and Java VM (Java virtual machine) can be installed. Because existing middle and high-end mobile phones such as Samsung's X859, LG's W800 etc. can basically support For camera, MP3 and other functions, it must be equipped with a large capacity memory, so it can also support Java VM.

[0033] figure 2 Shown is the basic flow of the method of the present invention. As the first step to realize the copyright protection mechanism, the present invention provides basic protection for MIDlets by means of digital signatures. Specifically, after the CP completes the development of a certain new MIDlets, if it needs to be tested on the mobile phone...

Abstract

A safety erection method of Java application program includes applying digital signature mode to provide basic protection on Java application program and then utilizing IMSI information in mobile phone to bind up with Java application program for realizing copyright protection in retransmission course.

Description

technical field [0001] The present invention relates to a kind of Java application program under J2ME architecture (referred to as MIDlets for short), makes it copy, install the method for still realizing copyright protection mechanism in the process of mobile information terminal such as mobile phone, belongs to digital rights management (DRM) technology field. Background technique [0002] Mobile communication services are increasingly popular, and the functions of various mobile information terminals such as mobile phones are also continuously enhanced. In this context, in order to further expand the service area and content of mobile communications, China Unicom launched a new value-added service - Unjia. This service supports the download and use of MIDlets on some mobile phones that meet the performance requirements. [0003] MIDlets are small applications in Java for mobile phones and embedded platforms. In the Unjia business, various MIDlets are developed by diffe...
