Abstract

The present invention relates to a technique which, in case a call or a text message is received, verifies whether a caller ID is legitimately transmitted or fabricated by a third person using the caller ID as well as contact numbers registered in a server by a service user, then notifies the user of a verification result. If the caller ID is legitimately transmitted, the present invention receives the location information of a caller and provides the location information to a receiver.

Description

[0001] The present invention relates to a method of confirming a calling number using Group information,

In the present invention, it is determined whether a caller's origination number is a call originated normally or a call originated by a third party, using a caller's origination number and a number registered by a service user in a server, It is about technology that tells. And, in case of a normal call, it includes a technique of receiving location information of a caller and providing location information to a receiver.

The outgoing call and the characters of the telephone include CID (Caller Identification), and the receiver identifies the caller through the caller's CID and accepts or rejects the call.

Such CIDs are maliciously altered by the caller and the recipient may receive unwanted calls. In addition to this, exposure of personal information may cause the user to receive unwanted spam calls / texts, voice phishing scams, Frequent cases are received.

The present invention provides a system for preventing spam, voice phishing, fraudulent phone calls by allowing a user to determine whether the user is a known sender or an officially authorized sender (e.g., a bank, government agency, school, etc.) Service.

In the present invention, a service is provided using origination number information that is basically provided in a domestic communication network.

When a phone / text message is received from a smartphone, the OS transmits the information to the listener module registered with the basic designated phone / text application or other application, so that the calling number information is included. And analyzing the information to determine whether or not the call is a call originating from a member of a previously registered group, and determining whether or not the originating number is changed in the case of originating the registered group. In addition, the present invention covers both the origination and the reception of the Internet telephony based on a smart phone as well as a smartphone, and a general landline telephone. However, in the case of ordinary landline phones, a separate hardware device capable of performing an app function can be connected to a general telephone so that the service can be used.

In addition, the smartphone user includes a technique of displaying the location of the caller on the smartphone of the receiver by using the GPS (Global Positioning System) -based location information provided by the smart phone and the location information provided by the mobile communication network.

In order to achieve the above object, the present invention relates to a Call Notification API provided in the anti-tampering client Framework layer of a smart phone and a phone / character discrimination anti-tamper client received at a telephone using caller ID information provided in a telephone network.

The sender's app provides a function to register in the service server information that the caller actually made a call to the group member in the specified group.

The receiver analyzes the calling number when receiving a call or a text message, displays the registered calling number (app DB and service sub DB) information on the screen, and displays the GPS position of the caller by driving the map app do.

Then, the server system and the service anti-tampering client are provided to inquire the user's registered group or personal address book information using the extracted CID.

In addition, as a basis for service provision, a user can create a group after service registration, and provide a function to designate a caller who wants to receive a phone call or a text by inputting an acquaintance and an institution address book information.

The present invention establishes an anti-tampering client and server system for a telephone set and provides the user with information on the actual origin and location of the caller registered in the service group, thereby preventing a criminal such as a phone call / It is possible to increase the reliability of the call contents by confirming the location of the caller by using the location information.

In addition, it is possible to effectively register and confirm the call by managing each group, not by each call number, in order to confirm the call.

Also, instead of managing the originating number for each individual, it is easy to maintain and extend the group by allowing members of the group to be registered and deleted together with the general members allowed by the grouping member.

1 is a configuration diagram of a service solution according to an embodiment of the present invention.
2 is a flowchart illustrating a procedure for using a service.

The present invention implements functions such as service subscription and group registration in a server web page, and a caller identification function based on caller identification according to RFC 3261 is provided in a change prevention client.

In the case of a smartphone, the call event listener registration function and the caller identification parameter provided in the anti-tampering client framework layer are used to authenticate the CID registered in the group and the personal address book registered by the user, Provides a software algorithm and anti-tamper client that outputs the originator's presence and the originator's location on the map. In the case of a smart phone-based Internet telephone or a general telephone, the service provider recognizes the caller number provided by the telephone network and provides the service. The hardware device for general telephone is divided into a calling number identification part and an internet connection part, and is configured as a device for displaying information.

In addition, it defines and implements the interface between the anti-tampering client and the web service function through the Internet network.

1 is a schematic representation of a tamper-proof service system.

The anti-tamper service system consists of a sender (anti-tamper client), a receiver (anti-tamper client), and a tamper-proof server.

(1) Member registration function / member registration processing function and login function / login processing function

Members are divided into group members and general members. The difference between group membership and general membership functions is the difference in creating groups. In other words, a group member forms a group, and a general member requests invitation to participate in the group through a group invitation function, and the general member receives a group invitation of the group member, do.

Grouping Members can create a group by playing the role of grouping. Members can add and delete contacts to be included in the group. When a group member installs a tamper-proof client and performs the above subscription and login procedures, he or she can see a list of the groups that included him as a member. Group members will be ready to use the service by approving the invitation of group membership (approval of group members, approval of use of location information).

The registration of the member is performed by creating and registering the member information (member registration function) using the homepage or the anti-tampering client, and the anti-tamper server performs the corresponding registration (member registration processing function).

end. Sign Up

Membership procedures are required to use this service. Membership can be made in two forms as follows. If you use it on a smartphone, you can download it through the app store (Apple, Play Store, etc.) like a common smartphone anti-tamper client for easy downloading and installation. .

- How to sign up with a regular web browser via the Internet

- How to subscribe through anti-malware client downloaded from Smartphone

I. login

After installing the anti-tamper client and signing up, proceed with the login process. Login is the step of entering the ID and password and connecting to the server. When activating the automatic login function, the ID and password are entered only once for the first time so that the automatic connection is established.

(2) Group management function and group management processing function

Grouping is a function to create a group. (If you use anti-tampering client installed on the phone, you can add and delete the group by using the phone's contact). For example, create a family group, a company group, a friend group, etc., and add or delete members to each group. The group management function is performed by the client, and the result is stored in the client DB (group management function). The server processes the group creation and member addition / deletion and reflects it in the server DB (group management processing function).

(3) Group invitation function and group management processing function

After adding or deleting members by group, invite the members to join the group by inviting group members (group invitation function). The group invitation request is received by the server, and the group member is requested to invite the group (group management processing function). At this time, it is recorded in the client DB and the server DB that the request is made.

(4) Group invitation approval function and group invitation approval processing function

General members who receive a group invitation request will approve the group invitation (group invite approvals). The server receiving the group invitation approval logs the approval to the server DB, sends the group invitation approval result (group invitation approval processing function), and the client of the group group notified of the group invitation approval authenticates the client DB Record.

The recording of the acknowledgment at the client and the server can be performed at the time of event occurrence and can also be performed through the synchronization process.

In the case of a general member, when the group invitation is approved, the information about the members of the related group is downloaded from the server and the group information is stored in the client DB.

(5) Outbound registration function and outbound registration processing function

And registers the origination information (group information, origination number, destination number, origination time, caller location information, etc.) in the server at the time of the originating of the client. At this time, only when the called party number is included in the group of the client DB, the calling information is registered in the server. However, it is possible to request the DB of the server to register the calling information without determining whether the client DB is included in the group. At this time, the server may record the calling information in the DB of the server on the basis of the calling number and the called number, or may simply register the calling information in all the groups to which the calling number belongs.

Search DB and translate the origination information into the encrypted data form in HTTP / 1.1 based JSON payload to the anti-tamper server only when there is the same number. The information to be registered includes the calling party number, the calling time, the calling party group, and the calling party location information.

(6) Client DB  And server DB  function

The group information (group name, member number, group member addition and deletion right according to the member number, permission request and approval completion information) is stored in the client and server DB. The DB also holds the origination information (group information, originating number, originator's location information) in the DB. Adding and Deleting Group Members by Member Numbers A permission field is a field for allowing a group member to perform a plurality of group management by granting permission to add and delete members of a group when a general member is added.

(7) Synchronization function

And synchronizes the group information and the calling information between the client and the server.

(8) Confirmation of calling information, outputting of calling information, processing of confirming calling information

When the called party receives the call, the called party's client searches the client DB information to see if it is a registered number in the group (this procedure may be selectively processed). If the called party is the number registered in the group, And requests confirmation of the origination information.

The server which has requested the confirmation of the outgoing information searches the server DB and provides the outgoing call information to the called party when the outgoing call number is registered, and the incoming client outputs this information (relieved caller place information) to the user.

When a call is received, the anti-tampering client searches the group DB held by the client, inquires of the anti-tamper server whether the same number exists or not, and if the actual call originated based on the inquiry result, , And if it is a telephone call that does not have an actual call, a popup window informs the user of a changed telephone warning message. If the user can not access the data network such as WIFI, 3G, 4G (LTE) according to the terminal environment, the mobile terminal transmits to the user whether the outgoing call is normal / changed by using SMS (Short Message Service) (SMS is transmitted over the voice network rather than the data network).

The location information of the originating information receives the location information data registered by the originator in the anti-tamper server from the server, drives the map application held in the smartphone, and displays the location of the caller on the map based on the received location information. Most popular smartphone map applications are Google Map, Apple Map, T-map, Naver Map, Daum Map, etc. It shows a list of installed map apps and allows users to make final selection.
