In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.
The method, the system and the storage medium for generating the wetland electronic atlas based on the encryption technology according to some embodiments of the present application are described below with reference to fig. 1 to 5.
As shown in fig. 1, the method for generating a wetland electronic atlas based on an encryption technology according to an embodiment of the present invention includes the following steps:
step S102: constructing a wetland electronic atlas, wherein the wetland electronic atlas comprises a resource library;
step S104: establishing an access layer for a user to access the wetland electronic atlas;
step S106: establishing an application layer for a user to manage the wetland electronic atlas, and setting browsing service in the application layer to realize browsing of the wetland electronic atlas;

wherein, the resource library includes: the system comprises a character library, a picture library and an area library, wherein the character library comprises character information of various wetlands, and the picture library comprises the following picture data: wetland in China and various provinces, ecological functional areas, bird migration channels, river dry flow, international important wetland, national important wetland, key survey wetland, lake wetland and watershed subarea; the dongle comprises a singlechip circuit with a USB interface, the singlechip circuit is embedded with an encryption program, and the wetland electronic atlas can be encrypted through the encryption program.
According to the wetland electronic atlas generation method based on the encryption technology provided by the embodiment, the resource library, the access layer, the application layer and the service layer are sequentially constructed, the wetland electronic atlas is encrypted by the dongle, and the encrypted wetland electronic atlas is generated. The access layer provides a channel for a user to access the access system through a client. The application layer is used for providing browsing services which are constructed by the background service module and meet different types of wetland resources so as to realize the browsing of the wetland resource management. The browsing service comprises thematic map classification retrieval, character content classification retrieval and wetland area graphical analysis. The service layer is used as a basic support platform of the system, so that the upper business application is constructed, assembled, deployed and managed through the service layer to realize information exchange in the system. The dongle comprises a singlechip circuit with a USB interface, the singlechip circuit is embedded with an encryption program, and the wetland electronic atlas can be encrypted through the encryption program.

Among other things, the algorithm of the encryption program may convert a number or character into an integer, such as DogConvert (1) =17345, DogConvert (a) = 43565. For example, there is a sentence in a program: a = Fx (3). The program will derive the value of variable a from the constant 3. Thus, the original program can be rewritten as: a = Fx (DogConvert (1) -17342), the constant 3 would not appear in the original program, but it would be given as DogConvert (1) -17342. Therefore, only the software writer knows that the constant of the actual call is 3. Without a dongle, the DogConvert function cannot return the correct result, nor will the a = Fx (DogConvert (1) -17342) result. The encryption method which can prevent the pirate user from obtaining the software use value is milder, more concealed and more difficult for the decryptor than the encryption method which warns and stops the illegal use. Additionally, the encryption lock and the read/write function can be used to read and write to the memory inside the encryption lock, 17342 in the above equation can also be written to the encryption lock memory, making the value of A completely dependent on the results of the functions DogConvert () and Dogread () and making decryption difficult.
