Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a network configuration diagram for explaining an actual home authentication system according to an embodiment of the present invention.

Referring to FIG. 1, a real place authentication system includes a real place location authentication apparatus 100, a base station 200, and a terminal 300.

The real place authentication apparatus 100 is a device for authenticating whether a user who holds a terminal is located in a residence by using the history of use of the terminal received from the base station 200. [

The real place authentication apparatus 100 groups the use histories of the terminals received from the base station 200 into a plurality of groups in order to authenticate whether or not the user holding the terminals is located in the residence.

The reason why the history of use of terminals is grouped into a plurality of groups is to determine which group among the plurality of groups the terminal position information received from the terminal 300 corresponds to, This is because the user can authenticate whether or not the user is located in the residence according to whether or not the coordinate information is grouped.

More specifically, the actual home authentication apparatus 100 groups the usage histories of the terminals received from the base station 200 into a plurality of groups. More specifically, the real home authentication apparatus 100 determines, based on the usage history of the terminals, The coordinate information on the position information is arranged on the coordinate system, and the coordinate information on the actual place of the user holding the terminal is arranged on the coordinate system.

Then, the real place location authentication apparatus 100 determines coordinate information for the terminal location information located at a specific radius as the grouping object data based on the coordinate information for the actual place of residence.

For example, the real place authentication apparatus 100 can determine coordinate information on the terminal location information existing within a radius of 10 km as the grouping object data based on the coordinate information on the actual place of residence.

The reason for determining only the coordinate information for the terminal position information located at a specific radius on the basis of the coordinate information of the actual place as the grouping object data is that the coordinate information for the terminal position information is all determined as the grouping object data, It is not necessary to consider the terminal location information located far away from the actual place of residence because the present invention authenticates whether the user is located in the actual place of residence.

The real place authentication apparatus 100 places each of the plurality of clusters representing each of the plurality of groups on the coordinate system on which the coordinate information for the terminal location information is arranged. At this time, each of the plurality of clusters may be disposed at an arbitrary position, or may be disposed at an intermediate point of the corresponding section after dividing the coordinate system into a plurality of sections.

The real place authentication apparatus 100 compares the coordinate information of each of the plurality of clusters with the coordinate information of the terminal position information, and groups the terminal position information into a specific cluster according to the comparison result. More specifically, the real place location authentication apparatus 100 calculates distance information between the coordinate information of each of the plurality of clusters and the coordinate information of the terminal location information, As shown in FIG.

If the above process is repeated until the entire coordinate information for the terminal location information arranged on the coordinate system is grouped into one of the plurality of clusters, the coordinates of the terminal location information The information will be grouped into any one of a plurality of clusters.

After completing the above process, the real place location authentication apparatus 100 calculates the density of each of the plurality of groups according to the distribution map of the terminal location information grouped into the group for each of the plurality of groups. The reason why the density of each of the plurality of groups is calculated in this manner is to calculate the reliability of the terminal location information received from the terminal 300 by checking how uniform the space occupying the plurality of groups is.

That is, when it is determined that a group having a high density among a plurality of groups is a group including location information of a user's actual place, and the terminal location information received from the terminal 300 is included in the group, Is located in the actual place of residence.

For this purpose, the real place location authentication apparatus 100 calculates the density of each of the plurality of groups according to the distribution map of the terminal location information grouped into the groups for each of the plurality of groups, And determine their respective rankings. That is, the group with the highest density of each of the plurality of groups is assigned the highest rank, and the group with the lowest rank is assigned the lowest rank.

The real place location authentication apparatus 100 calculates the number of terminal location information groups grouped into the groups by referring to one embodiment of the process of calculating the density of each of a plurality of groups, The density of each of the plurality of groups can be calculated.

In another embodiment, the real place location authentication apparatus 100 compares the center coordinate information of the group with the coordinate information of the terminal position information grouped into the group, calculates the difference distance for each of the plurality of groups, And assigns a weight to the terminal location information according to the distance.

For example, if the difference distance is less than 300 m, a weight of +2 points is given to the terminal position information. If the difference distance is less than 600 m, a weight of +1.5 points is given to the terminal position information. If the difference is within 900 m A weight of +1 point can be given to the terminal position information. Then, the real place authentication apparatus 100 can calculate the density of the corresponding group using the final weight of the weights assigned to the respective terminal location information and the number of the terminal location information grouped into the corresponding group.

In another embodiment, the real place location authentication apparatus 100 calculates the standard deviation of the group using the distribution map of the coordinate information for the terminal location information on the basis of the center coordinate information of the group for each of the plurality of groups , And the density of the group can be calculated using the standard deviation. In this embodiment, the real place authentication apparatus 100 can determine a group in which to perform grouping again among a plurality of groups according to the standard deviation. That is, the real place location authentication apparatus 100 can determine a group to be re-grouped if the standard deviation of the group is equal to or greater than a specific threshold distance.

In this case, the real place location authentication apparatus 100 divides the group into a plurality of subgroups, performs grouping again for each of the plurality of subgroups, and calculates the density of each of the plurality of subgroups as described above.

The real place authentication apparatus 100 determines the rank of each of the plurality of groups according to the density of each of the plurality of groups calculated through the above-described process, and determines the reference probability using the rank of each of the plurality of groups. For example, the real place location authentication apparatus 100 determines the reference probability to be 100% if the ranking of the group is within the upper 10%, and determines the reference probability to be 95% if the ranking of the group is within the upper 25% If the ranking is within the upper 40%, the reference probability is determined as 80%. If the ranking of the group is higher 60%, the reference probability is determined as 75%. Otherwise, the reference probability can be determined as 70%.

Then, the real-place authentication apparatus 100 refers to the predetermined benefit-point correction probability table to determine a correction probability corresponding to a point of interest of each of the plurality of groups. Thereafter, the real place authentication apparatus 100 corrects the reference probabilities by using the respective correction probabilities. For example, the real-place authentication apparatus 100 can determine the correction probability to be -20% if the group's point of interest is less than 10P, and correct the reference probability using the correction probability.

The real place location authentication apparatus 100 determines the distance of each of the plurality of groups from the group in which the coordinate information of the user's actual place of residence is grouped, determines the correction value according to the distance, and applies the corrected reference probability .

Upon receiving the terminal location information from the terminal after the plurality of groups are determined through the above process, the real location authentication apparatus 100 selects a group corresponding to the location information of the terminals among the plurality of groups, And can certify that the user holding the terminal is located in the residence according to the ranking of the corresponding group. For example, if the rank of the group corresponding to the location information of the terminal is 1, the real place authentication apparatus 100 can authenticate whether the user holding the terminal is located in the residence.

And receives terminal location information from the terminal 300. Then, the real place location authentication apparatus 100 selects a specific group corresponding to the terminal location information among the plurality of groups generated by grouping the use histories of the terminals.

The base station 200 stores the usage history of the terminal 300 and provides the usage history of the terminal 300 according to the request of the actual home authentication apparatus 100.

The terminal 300 can be implemented by a smart phone, a PDA, or the like as a terminal device possessed by a user. Such a terminal 300 provides a history of use to the base station 200 every time a telephone call, text, data, or the like is used according to a user's operation.

FIG. 2 is a block diagram for explaining an internal structure of a real-place authentication apparatus according to an embodiment of the present invention.

2, the real place authentication apparatus 100 includes a receiving unit 110, a real place authentication unit 120, a group creating unit 130, and a control unit 140.

The reception unit 110 receives the use history of the terminal from the base station and provides the history to the group generation unit 130.

Upon receiving the terminal location information received from the receiving unit 110, the real location authentication unit 120 determines the ranking of the group corresponding to the terminal location information among the ranks of the plurality of groups generated by the group generating unit 130 And determine whether the user who holds the terminal is located in the residence according to the ranking of the group.

More specifically, the actual place authentication unit 120 calculates the coordinate distance between the coordinates of the center coordinates of the group and the coordinates of the position information for each of the plurality of groups, selects the group having the shortest coordinate distance among the plurality of groups, It is possible to determine whether the user who holds the terminal is located in the residence according to the ranking of the group.

Upon receiving the usage history of the terminal from the reception unit 110, the group generation unit 130 arranges the coordinate information of the terminal location information on the coordinate system based on the usage history of the terminal, The coordinate information for the terminal location information located at a specific radius is determined as the grouping object data based on the coordinate information for the actual place of residence.

Then, the group generating unit 130 arranges each of the plurality of clusters representing each of the plurality of groups on the coordinate system on the coordinate system, and compares the coordinate information of each of the plurality of clusters with the coordinate information on the terminal position information And groups the terminal position information into specific clusters according to the comparison result.

The group generating unit 130 may calculate the density of each of the plurality of groups according to the distribution map of the terminal location information grouped into the groups for each of the plurality of groups and may calculate the rank of each of the plurality of groups according to the density of each of the plurality of groups You can decide.

In one embodiment, the group generating unit 130 may calculate the density of each of the plurality of groups using the number of the terminal location information grouped into the corresponding group for each of the plurality of groups.

In another embodiment, the group generating unit 130 may calculate a standard deviation of the group using the distribution map of the coordinate information for the terminal position information on the basis of the center coordinate information of the group for each of the plurality of groups, The group is divided into a plurality of subgroups according to the standard deviation, and grouping is again performed for each of the plurality of subgroups.

Thereafter, the group generating unit 130 calculates the probability of the corresponding group according to the density of groups in which the coordinate information of the user's actual place of residence is grouped for each of the plurality of groups. In one embodiment, the group generating unit 130 may calculate the probability of the group using Equation (1) below.

[Equation 1]

P = (R_P + A_P) x alpha

R_P: a reference probability according to the rank of each of a plurality of groups

A_P: Correction probability according to each point of the plurality of groups

α: Correction value according to the distance from the group in which the coordinate information for the actual place is grouped

Referring to Equation (1), the group generator 130 determines the reference probability R_P of the group using the rank of each of the plurality of groups, and refers to the predetermined probability-based correction probability table, A correction probability A_P corresponding to a point of interest is determined to correct the reference probability R_P. Then, the group generating unit 130 determines the distance of each of the plurality of groups from the group in which the coordinate information of the user's actual place of residence is grouped, determines the correction value? According to each distance, R_P + A_P).

The control unit 140 may control the other components of the real place authentication apparatus to provide a real place authentication procedure.

FIG. 3 is a flowchart for explaining an embodiment of a real-location authentication method according to the present invention. An embodiment disclosed in FIG. 3 relates to an embodiment in which a user possessing a terminal can authenticate whether or not a user is located in a residence using terminal location information received from the terminal.

Referring to FIG. 3, the real place authentication apparatus 100 receives terminal location information from a terminal (step S310). The real place authentication apparatus 100 selects a group corresponding to the terminal location information among a plurality of groups generated by grouping usage histories of the terminals (step S320). The real place authentication apparatus 100 determines the ranking of groups corresponding to the terminal location information among the plurality of groups (step S330). The real place authentication apparatus 100 judges whether the user holding the terminal is located in the residence according to the rank of the group corresponding to the terminal location information (step S340).

FIG. 4 is a flowchart for explaining an embodiment of a real-location authentication method according to the present invention. 5 to 8 are reference views for explaining the process of FIG.

One embodiment disclosed in FIG. 4 relates to an embodiment in which a plurality of groups can be created using the usage history of the terminal to authenticate whether a user holding the terminal is located in the residence.

Referring to FIG. 4, the real place location authentication apparatus 100 places coordinate information on terminal position information on a coordinate system based on a use history of the terminal (step 410). The real place authentication apparatus 100 arranges the coordinate information of the actual place of settlement of the user holding the terminal on the coordinate system (step S420). The real location authentication apparatus 100 determines coordinate information on the terminal location information located at a specific radius as the grouping object data based on the coordinate information of the real place of residence (step S430).

For example, as shown in FIG. 5, the real place authentication apparatus 100 can determine coordinate information on the terminal location information located in a radius of 10 km based on the coordinate information 510 about the real place as grouping object data.

The real place location authentication apparatus 100 places each of a plurality of clusters representing each of a plurality of groups on a coordinate system on a coordinate system (step S440). The real location authentication apparatus 100 compares the coordinate information of each of the plurality of clusters with the coordinate information of the terminal location information, and groups the terminal location information into one of the plurality of clusters (step S450). For example, the real place authentication apparatus 100 may generate a plurality of groups 610a to 610f by grouping the terminal location information into any one of a plurality of clusters as shown in FIG.

The real place authentication apparatus 100 calculates the density of each of the plurality of groups according to the distribution map of the terminal location information grouped into the groups for each of the plurality of groups (step S460).

In one embodiment of step S460, the real place location authentication apparatus 100 may calculate the density of each of the plurality of groups using the number of the terminal location information grouped into the corresponding group for each of the plurality of groups.

In another embodiment of step S460, the real place location authentication apparatus 100 compares the center coordinate information of the corresponding group with the coordinate information of the terminal position information grouped into the group for each of the plurality of groups, And weighting the terminal location information according to the difference distance, and calculating the density using the final weighting of the weighting factors and the number of terminal location information groups grouped into the group.

For example, as shown in FIG. 7, the real place authentication apparatus 100 transmits center coordinate information of the group 1 610a to the group 1 610a among the plurality of groups and coordinate information on the terminal position information grouped into the group 1 The difference distance is calculated, and the terminal position information can be weighted according to the difference distance. At this time, if the distance between the center coordinates of the group 1 610a and the coordinates of the terminal position information is within 300m, the weight of the terminal position information can be determined as +2.

In this way, the real place authentication apparatus 100 uses the final weights of the weights of the terminal position information grouped by the group 1 610a and the number of the terminal position information grouped by the group 1 610a, ) Can be determined. These benefits are used below to determine the correction probabilities used to correct the reference probabilities according to the density of each of the plurality of groups. This description will be described in more detail below.

In another embodiment of step S460, the real place location authentication apparatus 100 uses the distribution map of the coordinate information for the terminal location information on the basis of the center coordinate information of the group for each of the plurality of groups, Calculates the deviation, divides the group into a plurality of subgroups according to the standard deviation, and performs grouping again on each of the plurality of subgroups.

For example, when the real place authentication apparatus 100 occupies a large space in the upper, lower, left, and right sides, it is difficult to calculate the density of the group, so that the standard deviation is calculated as described above, And then performs grouping again. In one embodiment, if the X-axis or Y-axis standard deviation of the group is greater than or equal to a certain distance (for example, 500 m or more), the real place authentication apparatus 100 divides the group into a plurality of subgroups and performs grouping again . In another embodiment, the real place location authentication apparatus 100 does not perform grouping again for the group if the X-axis or Y-axis standard deviation of the group is not more than a certain distance (for example, 250 m).

Since the accuracy of the density of each of the plurality of groups is improved through the process of equalizing the space occupied by each of the plurality of groups as described above, when the rank of each of the plurality of groups is determined according to the density of each of the plurality of groups, Is improved.

The real place authentication apparatus 100 determines the ranking of each of the plurality of groups according to the density of each of the plurality of groups (step S470).

In step S480, the real place authentication apparatus 100 calculates the probability of the corresponding group according to the density of the group in which the coordinate information of the user's actual place of residence is grouped for each of the plurality of groups. More specifically, the real place location authentication apparatus 100 determines the reference probability of the group using the rank of each of the plurality of groups, and refers to the preset correction probability table to calculate a correction The probability is determined to correct the reference probability.

Then, the real place location authentication apparatus 100 determines the distance of each of the plurality of groups from the group in which the coordinate information of the user's actual place of residence is grouped, determines the correction value according to each distance, To be applied.

Since the real place authentication apparatus 100 calculates the density of each of the plurality of groups through the above process, accuracy of density is improved. Therefore, when the terminal location information is received, Can be accurately authenticated as to whether or not the user who holds the home location is located in the actual place of residence.

For example, the real place authentication apparatus 100 may determine that the user holding the terminal is located at the actual place of residence when the group of the grouped coordinate information of the terminal location information is high as shown in FIG. 8 (a) 8 (b), it can be determined that the user holding the terminal is located at a close position of the actual place of residence when the group density of group information is low, as shown in FIG. 8 (c) If the coordinate information on the terminal location information is not included in any group, it can be determined that the user who holds the terminal is not located in the actual place of residence.
