Embodiment Construction

[0028] The method for restricting the operation of illegal JAVA software by utilizing software watermarks proposed by the present invention has a flow chart as follows: figure 1 shown, including the following steps:

[0029] (1) Embed a watermark in the JAVA software submitted by the user, and the embedding process includes the following steps:

[0030] (1-1) Build a JAVA software watermark generation module, and generate a JAVA software watermark according to the identity of the user submitting the JAVA software;

[0031] (1-2) Construct a JAVA software watermark embedding module including multiple watermark embedding methods;

[0032] (1-3) Select a software watermark embedding method from the JAVA software watermark embedding module according to the requirements of the submitted JAVA software user. The specific process is as follows:

[0033] (1-3-1) If the user requires the software watermark to have strong robustness, select the dynamic watermark embedding method;

Abstract

The invention relates to a method for restricting illegal JAVA software operation by using software watermarks, belonging to the technical field of software protection. The method comprises the following steps of: embedding a watermark in JAVA software submitted by a user; then, constructing a JAVA software extraction module and a JAVA software watermark verification module in a JAVA software operation system; extracting the watermark from the JAVA software submitted by the user with a watermark extraction method in the water extraction module; and verifying the extracted watermark to determine the validity of the JAVA software submitted by the user. The method in the invention has good confidentiality, high safety, and better attack resistance capacity for attacks of malicious software. In the method, the software watermark has short extraction time, and the software embedded with the watermark can still keep good operation performance. The method has good portability, a watermark method is selected according to user demands, and the JAVA software requirement on safety and operation efficiency can be better satisfied.

Description

technical field [0001] The invention relates to a method for restricting the running of illegal JAVA software by using a software watermark, and belongs to the technical field of software protection. Background technique [0002] In an open network environment, the software running environment is faced with problems such as illegal program intrusion and diverse and heterogeneous system platforms, and JAVA software has been widely used because of its good portability. Therefore, it is important to ensure the security of the JAVA software running system. realistic meaning. [0003] In order to protect the security of JAVA software running system, the "sandbox" model has been widely used. In the JAVA "sandbox" model, the execution environment of JAVA software is strictly divided into two parts: the local code can access all the resources of the computer; while the remote code (mainly the Applet downloaded from the network) can only run in strict Inside the restricted sandbox....
