Software authorization trial method based on web service and signature certificate

Abstract

The invention relates to a web service and signature certificate-based software trial authorization method, which comprises the following steps that: a client loads a software verification module, the software verification module checks whether a local trial license digital certificate exists or not, a certificate verification step is started to verify the legality and the effective time of the trial license digital certificate if the local trial license digital certificate exists, otherwise a registration application step is started to transmit registration application information to a web server and acquire the trial license digital certificate with a private key signature of a developer from the web server. Compared with the prior art, the method has the advantages of low cost, easiness for implementation, simplicity in management, ideal copyright protection, no influence on total customer experiences in the trial software functions, and the like.

Description

technical field [0001] The invention relates to a software copyright protection method, in particular to a software authorization trial method based on web services and signature certificates. Background technique [0002] The vigorous development of various application software has promoted the progress of various industries and economic development, improved the efficiency of the whole society, and brought great convenience to people's production and life. However, the development of application software often requires huge Capital and time investment, especially long-term technology accumulation, but our country has a certain lack of intellectual property protection, coupled with the weak legal awareness of pirates, has led to frequent occurrence of software piracy, which seriously damages the interests of developers. The investment of developers and the labor of software developers can easily lose respect and returns, which affects the enthusiasm of developers and the lo...

Problems solved by technology

The advantage of this method is low cost and easy promotion, but the disadvantage is that there are many technical loopholes and the protection function is fragile

For example, time-limited authorization, as long as a system time lock tool is installed, the protection will be invalid

In addition, network authorization is used, users use real names or telephone registration applications, manual approval by developers, and remote online password verification methods. The advantage of this method is that the risk of cracking is controllable, and the disadvantage is that the maintenance cost is high.

[0006] In the article "Analysis and Implementation of Software Protection Technology" in the Journal of Wuhan University of Technology, Volume 31, Issue 6, it is proposed to use the Internet to release software protection schemes, which is theoretically feasible to a certain extent, but it does not describe how to implement the application submission. auto commit

In addition, the problem of one user registering multiple products of the developer is not considered. The user information, software and version information of this solution are obviously not enough, and the user and version management on the server side are not considered, which has obvious limitations.

[0007] The application of Chinese Patent Publication No. CN 1621992A is a copyright protection scheme using digital signature and computer fingerprint information authorization software. This scheme is mainly aimed at the genuine authorization of purchased users, but the limitation of this scheme is that it does not consider the replacement of user hardware damage. In some cases, the authorization failure is caused, and the authorization process is more complicated, and there are obvious deficiencies in the software trial for time or number of times.
