Embodiment 1
[0053] see figure 2 , image 3 According to the invention, the game level data running on the Android system is protected to prevent the level data from being illegally shared. Level data is a form of scene data, and the scene data of different games or applications is different. The scene data in this example refers to level data, including level pictures, level-related music and text, etc.
[0054] figure 2 Indicates the process of downloading the level data from the cloud server to the local, and then performing secondary encryption.
[0055] image 3 Indicates the process by which the application uses level data.
[0056] The application program described in this embodiment is the game program A, and the scene data is the level data of the game. The developer of the application saves the level data in the game to the cloud server.
[0057] Such as figure 2 As shown, firstly, the application program (that is, the game program A) is started.
[0058] When the gam...
Embodiment 2
[0075] see Figure 4 , this embodiment assumes that the application program is A. Application A is a level game application. Application A has 10 levels. Each level in application A has different scene information. Suppose the scene data are T1--T10. According to the embodiment of the present invention, the scene data T1-T10 in the application program A are encrypted and stored in the cloud server. When the user uses the application program A, the first level is opened by default. At this time, the application program A requests the corresponding level from the cloud server scene data T1.
[0076] The cloud server sends the encrypted scene data T1 to application A according to the request, and the local device decrypts the encrypted data after receiving it, and then A sends the user information (such as user name User1, user account Account1) to the cloud server, and the server according to User information generates a key K and saves it in the cloud server.
[0077] The cl...
Embodiment 3
[0080] see Figure 5 , the same as the previous embodiment, this embodiment assumes that the application is A, the application A is a level game application, the application A has 10 levels, and each different level in the application A has different scene information, assuming The scene data are T1--T10 respectively.
[0081] According to the embodiment of the present invention, the scene data T1-T10 in the application program A are all encrypted and stored in the cloud server. When the user uses application A, the first checkpoint is opened by default. At this time, the application program A requests the scene data T1 of the corresponding level from the cloud server.
[0082] The cloud server sends the encrypted scene data T1 to application A according to the request, and the local device decrypts the encrypted data after receiving it. Then application A sends user information (such as user name User1, user account Account1) to the cloud server.
[0083] The cloud server...
