SERVER AND OPERATING METHOD THEREOF
A server may include a communication interface for receiving a log in request for a video call service from a terminal, and for receiving at least one information to be used to determine a country of a log in attempt from the terminal; a memory for storing country information received from the terminal when subscribing the video call service of the terminal; and a processor for determining the country of the log in attempt of the terminal based on the at least one information, comparing a prestored country information corresponding to the terminal with the determined country of the log in attempt, and allowing the log in of the terminal depending on a result of the comparison.
1 . An operating method of a server for providing a video call service, the method comprising:
receiving, from a terminal, a log in request for the video call service;
requesting information to be used in determining a country of the log in request the terminal;
receiving the information from the terminal;
determining the country of the log in request based on the information;
comparing a prestored country information corresponding to the terminal and the determined country of the log in request; and
allowing the log in by the terminal depending on a result of the comparison.
2 . The operating method of claim 1 ,
wherein the information comprises Internet Protocol (IP) address information, Subscriber Identity Module (SIM) information, and Global Positioning System (GPS) information.
3 . The operating method of claim 2 ,
wherein the determining the country of the log in request based on the information comprises:
extracting a first country information from the IP address information, extracting a second country information from the SIM information, and extracting a third country information from the GPS information.
4 . The operating method of claim 3 ,
wherein the determining the country of the log in request based on the information further comprises:
in response to the first country information, the second country information and the third country information being the same, determining a country included in the first to third country information as the country of the log in request.
5 . The operating method of claim 3 ,
wherein the determining the country of the log in request based on the information further comprises:
in response to two or more of the first country information, the second country information, and the third country information including a same country, determining the same country included in the two or more countries information as the country of the log in request.
6 . The operating method of claim 3 ,
wherein the determining the country of the log in request based on the information further comprises:
in response to the first country information, the second country information, and the third country information being different from one another, giving each of the first to third country information a weight of different value, and determining a country included in country information to which the weight is given as the country of the log in request.
7 . The operating method of claim 1 ,
wherein the stored country information is information input by a user of the terminal when subscribing to the video call service.
8 . The operating method of claim 1 ,
wherein the stored country information is information determined using at least one of IP information, GPS information, and SIM information input by a user of the terminal when subscribing to the video call service.
9 . The operating method of claim 1 ,
wherein the allowing the log in of the terminal depending on a result of the comparison comprises:
in response to a country included in the stored country information and the determined country of the log in request being the same as the result of the comparison, allowing the log in of the terminal.
10 . The operating method of claim 9 ,
further comprising, in response to a country included in the stored country information and the determined country of the log in request not being the same as the result of the comparison, blocking the log in of the terminal.
11 . The operating method of claim 9 ,
further comprising, in response to a country included in the stored country information and the determined country of the log in request not being the same as the result of the comparison, requesting additional information to be used to determine the country of the log in request;
determining the country of the log in request based on the additional information;
comparing the country included in the stored country information with the determined country of the log in request; and
allowing the log in of the terminal depending on the result of the comparison.
12 . The operating method of claim 11 ,
wherein the additional information comprises time information set in the terminal, and locale information comprising country and language information set in the terminal.
13 . The operating method of claim 12 ,
wherein the determining the country of the log in request based on the additional information comprises extracting at least one fourth country information from the time information, and extracting a fifth country information from the locale information.
14 . The operating method of claim 13 ,
wherein the determining the country of the log in request based on the additional information further comprises:
in response to the fourth country information and the fifth country information being the same , determining a country included in the fourth country information and the fifth country information as the country of the log in request.
15 . The operating method of claim 11 ,
wherein the allowing the log in of the terminal depending on the result of the comparison comprises, in response to the country included in the stored country information and the determined country of the log in request being the same as the result of the comparison, allowing the log in of the terminal.
16 . The operating method of claim 15 ,
further comprising, in response to the country included in the stored country information and the determined country of the log in request not being the same as the result of the comparison, blocking the log in of the terminal.
17 . A computer readable recording medium having recorded thereon a program for performing a method according to claim 1 .
18 . A computer readable recording medium having recorded thereon a program for performing a method according to claim 3 .
19 . A computer readable recording medium having recorded thereon a program for performing a method according to claim 4 .
20 . A server comprising:
a communication interface receiving a log in request for a video call service from a terminal, and receiving information to be used to determine a country of the log in request;
a memory storing country information received from the terminal when the terminal subscribes to the video call service; and
a processor determining the country of the log in request based on the information, comparing a prestored country information corresponding to the terminal with the determined country of the log in request, and allowing the log in of the terminal depending on a result of the comparison.
