DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart briefly illustrating a caller authentication method according to the present invention.

When a call is originated from a caller terminal (hereinafter referred to as a caller call) (S100), it is checked whether or not the caller authentication service (secure call) exists (S110). If the caller authentication service is performed, the caller authentication service is performed ) The receiver terminal displays whether it is the authenticated caller (s130) and finally receives the call (s140)

2 shows a data flow diagram for a caller authentication method according to the present invention.

Referring to FIG. 2, the caller-side communication service provider confirms that the caller is a sender of the caller authentication service (secure call service), and performs caller authentication.

Caller authentication can be performed by verifying whether the caller is a trunked caller.

On the other hand, the originator authentication can be performed by a method in which the originating information is transmitted to the server of the originator's communication company by the originating information processing server interlocked with the originator's private branch exchange and mutually confirmed.

Here, a trunk connection refers to a connection using a centralized line connecting a local exchange and a local exchange for relaying inter-station signals. Public institutions, financial institutions, and the like are connected to the caller's communication company by a trunk line. The originator authentication service is a contract between a sender and a sender side communication company, and means a service for notifying whether a sender is a public entity through a receiver terminal.

The caller side communication provider performs the caller authentication process.

Specifically, the caller-side communication service provider verifies whether the caller authentication service target is a call from an authenticated caller. For example, by verifying that the caller's call has been received via the trunk line, the caller's call can be verified as a call from an authorized organization such as a public institution or a financial institution.

On the other hand, the originator authentication may be performed by a method in which the calling information is sent to the server of the sender side communication company by the additional device (originating information processing server) interlocked with the caller side private branch exchange and mutually confirmed.

When the caller is authenticated, the caller-side communication carrier generates first additional information indicating an identity and an originator name indicating whether or not the caller's call is the subject of the caller authentication service, and transmits the generated first additional information to the caller To the recipient carrier.

Table 1 shows an example of caller name.

Figure 112015125247113-pat00001

The codes "1xx" to "8xx" can be assigned for callers authenticated by the trunk connection. Code "9xx" can be assigned to an unrecognized top-level caller, that is, to a caller who does not authenticate the caller, and code "0xx" can be assigned to a caller call from abroad.

The sender name can be code and sender type information.

For example, "1xx" (code); "Seoul Metropolitan Police Agency", "9xx" (code); "Unauthenticated sender", "0xx"; And "caller from abroad ".

The first additional information may be transmitted through an IP (Internet Protocol) network between a caller's communication service provider and a receiver's service provider, or may be transmitted as a prefix to a gateway section or a Calling Identification Display (CID) between voice-based mobile communication networks.

The receiver side service provider verifies the caller authentication service processing (secure call processing).

Specifically, the receiver-side communication carrier confirms whether the first additional information is transmitted along with the sender call, and converts the first additional information into information used between the receiver's communication company and the receiver terminal, and provides the second additional information to the receiver terminal as the second additional information .

For example, the second additional information may be the sender type information included in the first additional information, and the receiver communication company may convert the second additional information into a push message and transmit the same.

The receiver terminal displays the second additional information, for example, the sender type information, together with the sender call (s140)

The recipient terminal can confirm the type of the sender through the second additional information.

Here, the recipient terminal may display an icon corresponding to the type of the sender. The recipient terminal stores an icon matching the sender type, extracts sender type information from the received second supplementary information, and displays an icon corresponding thereto.

3 shows a configuration of an embodiment of the sender authentication system according to the present invention.

3, the caller authentication system according to the present invention includes a caller-side communication company 200 that performs a caller authentication process on a caller call from the caller terminal 100, a caller- And a recipient-side communication company 300 that performs a corresponding sender authentication verification process and provides it to the recipient terminal 400.

The sender side communication company 200 includes a service subscription confirmation unit 210 and a sender authentication processing unit 220.

The service subscription confirmation unit 210 confirms whether the caller is a caller authentication service subscriber.

The sender authentication processing unit 220 performs authentication on the sender's call of the subscriber subscribed to the sender authentication service (secure call service), and transmits an identification (identification) indicating whether or not the sender's call is the sender's call subject to the sender authentication service, And provides the generated first additional information together with the caller call to the receiver-side communication company.

The caller authentication processing unit 220 can confirm whether the caller's call is a call from an authorized institution such as a public institution or a financial institution by checking whether the caller's call is received through the trunk line.

The first additional information may be transmitted through an IP (Internet Protocol) network between the caller-side communication company 200 and the receiver-side communication company 300 or may be transmitted as a prefix to the gateway interval or the CID value between the voice-based mobile communication networks.

The sender authentication unit 310 of the receiver side communication company 300 confirms whether or not the first additional information indicating the identity and the sender name is added to the sender call received from the sender side communication company 200, And provides the second additional information to the receiver terminal 400 together with the caller's call.

The second additional information provided from the receiver side communication company 300 to the receiver terminal 400 may include an information providing method commonly used between the receiver side communication company 300 and the receiver terminal 400 such as a push message ). ≪ / RTI >

Since the receiver side communication company 300 may be various and the recipient terminal 400 may be various, it is difficult to specify one by one, but a push message is preferred by most of the communication companies because most recipient terminals can process the same.

Alternatively, an application for the originator authentication service may be loaded on the recipient terminal.

The receiver terminal 400 displays the sender call and the second additional information provided from the receiver-side communication company 300 on the display unit 410.

For example, the name of the caller may be displayed on the display unit 410 as "Seoul Local Police Agency "," unauthenticated sender ", "sender from abroad ".

The receiver can confirm whether or not the call is the call originator authenticated by the second additional information displayed on the receiver terminal 400. [

4 shows a configuration of another embodiment of the sender authentication system according to the present invention.

Another aspect of the caller authentication system according to the present invention shown in FIG. 4 is that the calling information processing server 120 is provided on the caller side and the calling information receiving unit 230 is further provided on the calling side communication company 200 3 is distinguished from the embodiment of the sender authentication system according to the present invention shown in FIG.

The calling information processing server 120 acquires the calling information as an event and provides the calling information to the calling information receiving unit 230 of the calling party communication company 200. The calling information receiving unit 230 transmits the received calling information to the calling party And provides it to the authentication processing unit 220.

The sender authentication processing unit 220 compares the trunk line identification and the origination information with each other to authenticate the sender.
