Embodiment 1

[0041] see figure 1 , an embodiment of the present invention provides a method for sending positioning information, including:

[0042] Step 101: Encrypt the location information with the control key to obtain location ciphertext, encrypt the control key with the product key to obtain service authorization information, and encrypt the product key with the temporary user key to obtain temporary user authorization information;

[0043] Step 102: receiving the user authentication information sent by the terminal, the user authentication information includes the identification of the terminal, the card identification of the secure digital SD card and the user account number;

[0044] Step 103: Authenticate the terminal according to the user authentication information;

[0045] Step 104: When the terminal authentication is successful, according to the user account included in the user authentication information, send the temporary user key and temporary user authorization informat...

Embodiment 2

[0055] An embodiment of the present invention provides a method for sending positioning information.

[0056] In order to know the location of a specific person at any time, the user can use the positioning service. When the user needs to check the location of the specific person, the server will locate the terminal corresponding to the specific person to obtain the location information of the specific person, and then the server can use the present invention to implement The method provided by the example sends the location information of a specific person to the terminal corresponding to the user.

[0057] Wherein, the specific person may be a child, an elderly person, or a suspect.

[0058] see figure 2 , the method specifically includes:

[0059] Step 201: the terminal sends user authentication information to the server, and the user authentication information includes the identification of the terminal, the card identification of the SD (Secure Digital Memory Card, sec...

Embodiment 3

[0122] see image 3 , an embodiment of the present invention provides a method for sending positioning information, including:

[0123] Step 301: Send user authentication information to the server, the user authentication information includes the terminal ID, the card ID of the secure digital SD card and the user account, so that the server authenticates the terminal according to the user authentication information;

[0124] Step 302: When the authentication is successful, receive the temporary user key, temporary user authorization information, service authorization information and location ciphertext sent by the server;

[0125] Step 303: Obtain the root key from the SD card;

[0126] Step 304: Determine the type of location service according to the temporary user authorization information, and start the location service mode corresponding to the type according to the determined type;

[0127] Step 305: Decrypt the temporary user authorization information according to the ...

Abstract

The invention discloses a method and a device for transmitting positioning information and belongs to the field of navigation positioning and information safety. The method includes encrypting positioning information by control keys to obtain positioning ciphertexts, encrypting the control keys by product keys to obtain service authorization information, and encrypting the product keys by temporary user keys to obtain temporary user authorization information; receiving user authentication information transmitted by a terminal; authenticating the terminal according to the user authentication information; transmitting the temporary user keys and temporary user authorization information to the terminal according to the user authentication information when authentication of the terminal succeeds, and transiting the service authorization information to a broadcasting channel; transmitting the positioning ciphertexts to the terminal so as to transmit the positioning information to the terminal. The device comprises an encrypting module, a receiving module, an authentication module, a first transmission module and a second transmission module. By the method and the device for transmitting positioning information, safety in transmission of the positioning information is improved.

Description

technical field [0001] The invention relates to the fields of navigation and positioning and information security, in particular to a method and device for sending positioning information. Background technique [0002] At present, in order to know the location of a specific person at any time, more and more users start to use location services. In the positioning service, the server can obtain the location information of a specific person. When the user requests to view the location of the specific person, the server needs to send the obtained location information to the terminal corresponding to the user. For example, a child is a specific person. The server locates the terminal corresponding to the child and obtains the child’s location information. When the terminal corresponding to the child’s parent requests to view the child’s location, the server needs to send the child’s location information to the parent. the corresponding terminal. [0003] Currently, the prior a...
