Software protecting method and software sale method based on same

Abstract

The invention discloses a software protecting method, which is specially characterized in that: functional decomposition is carried out on application software by a developer; the application software consists of a basic function and a plurality of special functions and is started by using an encrypted lock; the software is activated by adding a main registration code after the software is started; the activated software only has the basic function; the special functions of the software are at a non-activated state; the special functions are activated by adding a secondary registration code; and one special function corresponds to one secondary registration code. The invention provides the software protecting method which combines a hardware encryption method and a software encryption method. The functional decomposition of the software is carried out in a manner of activating through a plurality of registration codes by using an encryption lock and the registration codes which are in a combined manner, so that the difficulty of resolving the software is increased. The developer sells the application software with complete functions in a non-activated state to a user, and charges using fees of the user by controlling the quantity of the activated functions of the software and a time period of activating the software, so that the benefits of the developer and the user can be maximized.

Description

technical field [0001] The present invention relates to the field of software protection, in particular to a software protection method for encrypting software programs to prevent piracy and a software sales method based on the method, in particular to an inkjet printer RIP software protection method and a method based on the method Implemented RIP software sales method. Background technique [0002] With the rapid development of automation technology, software programs play an increasingly important role in the new product development process. However, software products are easily pirated, which greatly affects the legitimate rights and interests of developers. How to effectively protect their own software technology from plagiarism has gradually become the research focus of various software development companies. There are many software anti-piracy technologies, methods and products in the prior art, which are generally divided into two types: hardware (such as dongle) a...

Problems solved by technology

[0003] At present, the software sales method is mainly customized by operators and centralized procurement. Due to the differences in the market prices of these different customizations, some illegal users upgrade different customized software versions to carry out cross-selling sales and illegally make profits.

The same application software is sold in different language versions in different regions, such as English version, Chinese version, etc. There are price differences between these versions. In addition, the prices of the same application software sold to different price machines are also different, which has led to some illegal businessmen Or users make profits by illegally upgrading the version, causing different operators to resell application software for price difference, and a large number of parallel imports hit the market, which greatly affects the interests of developers

Since different users have different needs for software functions, if the developer develops software with different software functions, it will increase the research and development costs. If the developer sells the software with full functions to users at a lower price, the research and development costs cannot be recovered; For users, it is bound to be a waste to buy a set of software with complete functions at a higher price, but they do not use some functions.

It can be seen that the sales methods of existing application software can no longer meet the needs of the market
