Software authorization is an extension and development of the concept of software protection. The software authorization aims to make a software user use the software according to a purchase license, and relates to the installation number of the software, the use time, the application range, the functional sub-modules and the like. For software protection, the core idea is to prevent software from being pirated.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment provides a software authorization method based on a block chain, which is strong in universality and high in software security after authorization.
In this embodiment, the protected software authorization method is implemented based on the blockchain, so that a blockchain system with a corresponding size for managing authorization information needs to be maintained before authorization. When the blockchain system is selected, different blockchain systems can be selected according to the specific authorized scene of the software. If the authorization scenario is software batch authorization inside an enterprise, a private chain system running inside the enterprise can be adopted; if the authorization scene is software batch authorization facing a plurality of enterprises, a alliance connection system running among the plurality of enterprises can be adopted; if the authorization scenario is software authorization for individual users of the internet, a public link system running on the internet may be employed.
Under the specific scene of software authorization, the requirements on the performance and the storage of the block chain are not high, so that the requirement on an authorization function can be met by adopting an extremely light-weight block chain system, and the execution of the software cannot be greatly influenced.
Fig. 1 is a flowchart of a software authorization method based on a block chain according to an embodiment of the present invention, and referring to fig. 1, the method specifically includes the following steps:
and S1, adding a block chain module in the software to be authorized.
Since the blockchain system is also a software system, the blockchain system and the software to be authorized are seamless products. The addition of the blockchain module in the software to be authorized does not affect the software. The configuration information required by the blockchain module may be incorporated into the configuration information of the software itself.
Since the software may be written in various programming languages, the blockchain system selected by us needs to be able to solve the problem of information compatibility caused by various programming languages. Therefore, some information encoding modes with good compatibility can be adopted, such as: json, protobuf, etc.
S2, presetting first software authorization information and writing the first software authorization information into the blockchain system to obtain first execution permission information.
When a software user purchases software from a software developer, the software user can obtain first software authorization information, and the software is authorized and can be started through verification of the blockchain system.
When the software is deployed, setting first software authorization information which can be identified by the blockchain system is carried out. The software user purchases first software authorization information from a software developer, the software developer writes the first software authorization information into the blockchain system, the first software authorization information is identified and executed by the blockchain system, then first execution license information is obtained, the blockchain records the first execution license information of corresponding software, and the first execution license information is used when the software is started.
Specifically, the software developer writes first software authorization information into the blockchain system, which includes the following sub-steps:
s21, the blockchain system receives the first software authorization information;
s22, identifying and executing the first software authorization information by the blockchain system, and acquiring first execution permission information;
s23, the blockchain system records the first execution permission information.
Of course, before the blockchain system accepts the first software authorization information, the software developer needs to send the first software authorization information to the blockchain system through the corresponding node.
S3, when the software to be authorized is started, the blockchain module is started and accesses the blockchain system.
When the software to be authorized is started, the blockchain module is started first. After the blockchain module is started, the blockchain system can be accessed, and information in the blockchain system is read for communication transmission.
S4, checking the first execution permission information, and running the software if the first execution permission information is valid; otherwise, operation is refused, which comprises the following sub-steps:
s41, the blockchain module reads the first execution permission information in the blockchain system.
Specifically, after the blockchain module accesses the blockchain system, the information in the blockchain can be read, so as to find the pre-recorded first execution permission information of the software to be authorized.
And S42, judging whether the first execution permission information is valid, if so, operating the software, and if not, refusing to operate the software.
So far, the software is authorized and can be normally used.
After the software is authorized, the software has a certain use validity period, and after the authorization is expired, the software stops running, and a software user can re-authorize the software as required.
Therefore, in this embodiment, a software authorization method based on a blockchain further includes:
judging whether the first execution permission information is in the validity period or not when the software is used, and prompting a user to re-authorize if the first execution permission information is expired and invalid;
and the user autonomously selects whether to re-authorize, and if so, prompts the user to purchase second software authorization information for re-authorization.
Wherein the re-authorization comprises the steps of:
setting second software authorization information and writing the second software authorization information into the block chain system to obtain second software execution information;
when the software to be authorized is started, the block chain module is started and connected to the block chain system;
checking second software execution information, and running the software if the second software execution information is valid; otherwise, operation is refused.
According to the software authorization method based on the block chain, software is authorized through the block chain, and the characteristics of high efficiency, safety, traceability and difficult tampering of the block chain are utilized, so that the software authorization method is high in universality, the safety of the software after authorization is high, software piracy through illegal behaviors such as private copy, system time modification, authorization information resetting and the like can cause that the software cannot run through authorization verification on the block chain, and due to the characteristics of the block chain, software can be cracked through a delusional image in a manner of breaking the block chain, and the software is almost impossible.
