Abstract

A location-based service system and method, which allows a location-based service server connected with a communication device and a cloud data server to perform registration authorization procedures and service authorization procedures using an international mobile subscriber identity of the communication device that cannot be easily modified or forged in the registration and service modes, so that a user may obtain a specific location-based service result via the communication device, and this distributed authentication technique reduces the risk of data theft while increasing the flexibility and convenience in obtaining services.

Claims

1. A location-based service system for providing a location-based service result to a communication device connected thereto, the system comprising:

a location-based service server for receiving a first account information and a first service authentication code transmitted by the communication device in a registration mode, the location-based service server comprising a user repository and an authentication module, wherein the authentication module authenticates the received first service authentication code, and upon authentication, stores the received first account information in the user repository, and generates a first cloud authentication code based on the received first service authentication code; and

a cloud data server comprising a communication device repository for receiving the first cloud authentication code and storing the first cloud authentication code in the communication device repository, wherein the location-based service server receives a second account information and a second service authentication code transmitted by the communication device in a service mode, so as to make authentication module authenticate the second account information based on the first account information stored in the user repository, and upon authentication, the authentication module generates a second cloud authentication code based on the received second service authentication code, and authenticates the second cloud authentication code based on the first cloud authentication code stored in the communication device repository, such that the location-based service server provides a specific location-based service result to the communication device.

2. The location-based service system of claim 1, wherein the location-based service server further comprises a service module and a result intepretation module, and the cloud data server further comprises a service data repository and a location information repository;

wherein the service module obtains location information from the communication device after the authentication of the second cloud authentication code is completed in order to provide an original service result based on data in the service data repository to the result intepretation module;

the result intepretation module adjusts the original service result based on a privacy setting transmitted by the communication device to generate the location-based service result and transmits the location-based service result to the communication device, and the location-based service server processes the location information based on the privacy setting transmitted by the communication device to store the processed location information in the location data repository using the first or the second service authentication code as an identifier.

3. The location-based service system of claim 1, wherein the communication device performs a secure hash algorithm on an international mobile subscriber identity of the communication device to generate the first and the second service authentication codes, and the first and the second account information are inputted by a user via the communication device.

4. The location-based service system of claim 1, wherein authenticating the received first service authentication code by the authentication module includes analyzing the first service authentication code to obtain a mobile country code and a mobile network code, and connecting to an external mobile communication operation server to compare the mobile country code and the mobile network code, and the authentication module performs a secure hash algorithm on the first service authentication code and the second service authentication code to generate the first cloud authentication code and the second cloud authentication code, respectively.

5. A location-based service method for allowing a communication device connected with a location-based service server and a cloud data server to obtain a specific location-based service result, the method comprising the following steps:

(1) receiving by the location-based service server a first account information and a first service authentication code transmitted by the communication device in a registration mode;

(2) authenticating by the location-based service server the received first service authentication code, and upon authentication, storing the first account information;

(3) generating by the location-based service server a first cloud authentication code based on the received first service authentication code, and storing the first cloud authentication code in the cloud data server;

(4) receiving by the location-based service server a second account information and a second service authentication code transmitted by the communication device in a service mode;

(5) authenticating by the location-based service server the received second account information based on the stored first account information, and upon authentication, generating the second cloud authentication code based on the received second service authentication code; and

(6) authenticating by the location-based service server the second cloud authentication code based on the first cloud authentication code stored in the cloud data server, and upon authentication, having the location-based service server provide a specific location-based service result to the communication device.

6. The location-based service method of claim 5, wherein step (1) further comprises having the communication device performe a secure hash algorithm on an international mobile subscriber identity of the communication device to generate the first service authentication code, and receive the first account information inputted by a user via the communication device, and step (4) further comprises having the communication device performe a secure hash algorithm on the international mobile subscriber identity of the communication device to generate the second service authentication code, and receive the second account information inputted by the user via the communication device.

7. The location-based service method of claim 5, wherein in step (2) the location-based service server analyzes the first service authentication code to obtain a mobile country code and a mobile network code, and connects to an external mobile communication operation server to compare the mobile country code and the mobile network code, so as to complete the authentication of the received first service authentication code.

8. The location-based service method of claim 5, wherein in step (3) the location-based service server performs a secure hash algorithm on the first service authentication code to generate the first cloud authentication code, and in step (5) the location-based service server performs a secure hash algorithm on the second service authentication code to generate the second cloud authentication code.

9. The location-based service method of claim 5, wherein step (6) in which the location-based service server provides the location-based service result to the communication further includes the following steps:

having the location-based service server obtaine location information from the communication device to obtain original service result based on data of the cloud data server;

having the location-based service server adjuste the original service result based on a privacy setting transmitted by the communication device so as to generate the location-based service result; and

having the location-based service server provide the generated location-based service result to the communication device.

10. The location-based service method of claim 9, further comprising having the location-based service server processe the location information based on the privacy setting transmitted by the communication device to store the processed location information in the cloud data server using the first or the second service authentication code as an identifier.
