The invention relates to a GPS navigation method and a system and comprises that a navigator sends a navigation requirement to a calling center, wherein, the navigation requirement comprises the information about the present position of the navigator, the information about the position of the destination and the ID information of the navigator; the calling center formulates a routes plan based onthe navigation requirement and a dynamic traffic information; the calling center delivers the routes plan and an authorization information for activating a map file in the navigator to the navigator;the navigator receives the routes plan and the authorization information and activates the map file to display the planed routes; in the running process of the vehicle, the calling center formulates a novel routes plan according to the latest position information and the dynamic traffic information sent out by the navigator and delivers the novel routes plan to the navigator. In addition, the navigator sends out the edition information of the map file corresponding to the road sections around the present position stored in the navigator while sending out the present position information; the calling center compares the received edition information with the edition of the map used by the calling center and then determines the data increment of the map and delivers the data increment to thenavigator.

The present invention provides a method for assigning usage rights to users, including: receiving a request for assigning the user a role among one or more roles that follow predetermined social rules in a virtual social space; A role list of the one or more roles in the virtual social space, wherein each data item in the role list represents one of the one or more roles in the virtual social space and includes the relationship between the one role and the predetermined social interaction Use rights associated with rules: in response to associating the user with a data item in the role list, granting the user the use rights associated with a predetermined social rule of the role included in the data item. The present invention also provides corresponding devices and computer-readable storage media.

The present application discloses a method and device for car data diagnosis. The method includes: receiving an access request sent by a diagnostic device. The access request includes a first digital abstract, a joint serial number and data to be processed, wherein the data to be processed includes vehicle data and Indication information used to indicate at least one request algorithm, the first digital digest is obtained by hashing the data to be processed, the serial number of the connector, and the device ID of the diagnostic device; judging whether the device ID is legal according to the access request; judging the device ID If it is legal, judge whether the access request conforms to the preset policy; if it judges that the access request conforms to the preset policy, use at least one request algorithm to process the vehicle data to obtain a diagnosis result; and send the diagnosis result to the diagnosis device. The application can prevent the algorithm used for diagnosing the automobile data from being maliciously cracked and illegally used, and realizes the safety diagnosis of the automobile data.

The invention relates to an intelligent auction method for a click auction website. The method comprises a login step and an auction step. In the login step, firstly, the method determines whether a user is a registered user; secondly, a user name and a password are entered, a request including target_id is initiated, and whether the user is registered is judged, a Token code is returned and the method enters a third step if the user is registered, or an error message is returned if the user is not registered; and thirdly, the Token code is used to connect with a Node, a long connection is set up, and according to the target_id in the request, the user joins a corresponding room where a target that bidders / auctioneers intend to bid for / auction is. In the click auction website, each target is corresponding to a room, bidders and auctioneers participating in the auction of the target all join the room; the room in the Node is like a chat room, messages of operations of the bidders and auctioneers are all broadcasted in real time in the room, and the messages are not broadcasted to other irrelevant users.

The invention discloses a software anti-crack method and system. The method comprises the steps that terminal equipment acquires an application private key from an application management server when the terminal equipment needs to install a main application file of an application, and if acquiring fails, installation is stopped; when the terminal equipment receives a function execution command to the application for the first time, the terminal equipment applies to the application management server for the application function load authorization, after the authorization is acquired, a class SEC file of the application is loaded, the SEC file is encrypted by means of the application private key, the acquired encrypted file F[SEC] is saved, and the application private key and a plaintext of the SEC file are deleted; when the terminal equipment receives the function execution command to the application not for the first time, the terminal equipment applies to the application management server for a decryption key corresponding to the application private key, the applied decryption key is utilized for decrypting the encrypted file F[SEC], the plaintext of the SEC file is acquired and loaded, and after loading is finished, the decryption key and the plaintext of the SEC file are deleted. By means of the software anti-crack method and system, the software can be effectively prevented from being cracked maliciously.

The invention provides a method and device for encryption / decryption of an executable program data package. The method comprises the steps that the executable program data package is acquired; based on preset rules, the executable program data package is divided into multiple original documents; a first secret key is used to encrypt the multiple original documents respectively, so that encryption documents which have one-to-one correspondence relations with each original document respectively can be obtained; the multiple encrypted encryption documents are received; a second secret key corresponding to the first secret key is used to decrypt the multiple encryption documents respectively, so that the multiple original documents which have the one-to-one correspondence relations with the encryption documents can be obtained; and index information of the original documents are used respectively to reform the multiple original documents, so that the executable program data package can be obtained. The method and the device provided by the invention have the advantages that vicious decryption of the executable program data package caused by theft of a single secret key in the executable program data package can be prevented; a probability of the vicious decryption of an application program can be reduced; and data safety of the application program can be enhanced.
