Abstract

PURPOSE: A method for providing a CID(Caller Identification) service using fingerprint recognition is provided to transfer an actual terminal user's information to a terminating side by providing caller information on the basis of a caller's fingerprints. CONSTITUTION: A touch pad for fingerprint recognition is installed at a calling-side terminal(10). If the user of the calling-side terminal grips the touch pad, the CPU of the mobile terminal detects and analyzes the user's fingerprints and converts them into a digital signal. A digital signal processor modulates the digital signal and transmits it to an MSC(30). The MSC(30) forwards the fingerprint data to a personal information database(40) in an associated central office. The personal information database(40) searches for a subscriber matched with the fingerprint data and reports relevant subscriber information to the MSC(30). The MSC(30) sends a paging signal to a called-side telephone terminal. At the same time, the MSC(30) transmits the subscriber information at a frequency different from the paging signal.

Description

A method for providing a caller identification service using fingerprint identification technology

The present invention relates to a caller identification (CID) telephone, and more particularly, does not display the telephone number of the calling party telephone on the called party telephone, but recognizes the user's fingerprint in the calling party telephone based on the fingerprint information. The present invention relates to a method for providing more accurate caller data than the existing caller identification (CID) service by displaying caller information on a telephone.

In recent years, caller identification (CID) telephones capable of displaying the telephone number of the calling station telephone have been developed and sold. A caller ID phone with a small LCD display panel for displaying the caller displays the phone number and name of the caller on the LCD display panel as the phone rings and the user of the caller ID phone can easily identify who the call is from. It is convenient in many ways.

In order to receive the caller identification service as described above, the user of the called party must apply for the caller identification service to each telephone company. When any telephone user calls the subscriber who applied for the caller ID service, the exchange on the called party's side confirms that the subscriber of the called station phone is a subscriber of the caller ID service. If the service subscriber is correct, the exchange sends a call signal of 20Hz frequency to the called party, notifying that the call has been received, and simultaneously checking the database of each operator's telephone station where the terminal subscriber's information is stored in advance. Send the same data as the name of the signal to the destination station through a separate frequency signal. Then, the caller's telephone number, name and calling time are normally displayed on the LCD display panel of the called party's phone between the first calling ring and the second calling ring of the called country. Therefore, the called party's telephone subscriber can know from whom the call originates from the calling party's telephone number displayed on the LCD display panel when the telephone rings.

However, such a conventional caller identification service may search the caller only based on the telephone number of the calling party's telephone terminal, so the actual caller may not be displayed correctly. That is, even when a person calls a phone terminal of another person other than his or her own phone, the caller displayed on the called party's phone terminal is not the actual caller but the owner of the calling party's terminal, that is, the calling party. Only the subscriber information of the telephone terminal on the side is displayed. In this case, since the information of the actual correct caller and the subscriber of the calling terminal does not match, the called party identification service subscriber of the called party cannot confirm the correct caller information.

The present invention is to improve the problems of the conventional caller identification service as described above. Accordingly, the present invention provides a method for accurately displaying the caller's actual information on the called party's telephone terminal even when the caller is a person other than the calling party's subscriber. For the purpose of Another object of the present invention is to provide a caller ID service system capable of implementing the above method.

1 briefly illustrates a configuration of a caller identification service system using fingerprint recognition according to the present invention.

Figure 2 illustrates in more detail the configuration of a caller identification service system using fingerprint recognition, in particular the configuration of a fingerprint recognition telephone terminal according to the present invention.

In the present invention, a method for providing a caller identification service by fingerprint recognition for achieving the above object includes: a caller recognizes a user's fingerprint and the user's fingerprint when the caller's telephone user places a finger on the touchpad of the caller's telephone terminal. Digitally modulating information about the pattern and sending the same to the exchange; Sending, by the exchange, the digitally modulated fingerprint pattern information to a personal information database; A personal information database searching for a user whose fingerprint pattern matches the digitally modulated fingerprint pattern information and transferring the information to the exchange; An exchange receiving information of the calling party telephone user from the personal information database, digitally modulating the information, and transmitting the digitally modulated calling party telephone user information to the called party's telephone terminal together with a call signal indicating an incoming call; ; And demodulating the information of the digitally modulated calling party telephone user on the display panel by the called party's telephone terminal.

In still another aspect of the present invention, a system for providing a caller identification service using fingerprint recognition includes: a calling party telephone terminal having a touch pad for fingerprint recognition; A telephone exchange which connects a line of the calling station with the called station; A personal information database storing various types of information about the subscriber; And a called terminal having a caller display function.

Now, with reference to the accompanying drawings will be described in more detail the configuration and operation of the present invention.

Fingerprints have been used to identify people because their sweat glands are raised to form a certain pattern, and each person has a unique shape that does not change as it is. In particular, with the recent popularization of the biometrics field, various devices for automatically verifying identity in areas requiring security such as access control, time and attendance management, and e-commerce authentication are being developed. An automatic fingerprint recognition system is one of them. .

In the fingerprint recognition technology, there are two types of technologies that have been recently developed and used, such as an optical method (Frustrated Total Internal Reflection) and a silicon chip method (Silicon Chip Sensing). Currently, these two methods are commonly used as a representative method for detecting the shape of a fingerprint. Optical method is the most widely used method. Shooting strong light on a platen reflects the fingerprint shape of the fingertip placed on the platen, and the reflected fingerprint image is passed through the high refractive lens to be input to the CCD to recognize the shape of the fingerprint. The method using silicon chips utilizes the electrical conduction properties of the skin. When a fingertip is touched on the surface of the silicon chip, a special shape of the fingerprint contacted to the chip surface is read as an electrical signal.

The present invention utilizes such a fingerprint recognition technique to achieve the object of the invention. In other words, the identity of the caller is not verified by the calling party's telephone number, but by the caller's fingerprint recognized by the calling party's phone. Figure 1 shows briefly the system configuration of the present invention for this purpose. 1, the operation of the present invention will be briefly described first. According to the present invention, at least the calling terminal 10 is provided with a touch pad for fingerprint recognition. The fingerprint recognition touch pad may be either an optical method or a silicon chip method. When a telephone user grabs the fingerprint recognition touchpad by hand, the CPU inside the telephone terminal detects and analyzes the shape of the fingerprint and converts the digital signal into a digital signal, and the digital signal processor modulates the digital signal to generate a normal CID. It transmits to the switchboard 30 at the same frequency as the frequency used for the service. The exchange 30 then transfers the fingerprint data to the personal information database 40 of each operator telephone station. The personal information database 40 stores the information of each subscriber, including the fingerprint form of the telephone subscriber. The personal information database 40 which receives the fingerprint data from the exchange 30 finds a subscriber having a form that matches the fingerprint data from the stored subscriber information and notifies the switch 30. The switch 30 then sends a call signal to the destination station telephone terminal to indicate that the call has been received and simultaneously transmits subscriber information at a frequency separate from the call signal. Therefore, the called party's telephone terminal can inform the user of the information of the actual caller, not the owner information of the calling party's telephone terminal.

Figure 2 shows in more detail the system configuration according to the invention, in particular the configuration of a telephone terminal. Now, the configuration and operation of the present invention will be described in more detail with reference to FIG. 2.

2 exemplarily shows a case where the calling terminal 10 and the called terminal 50 are wireless telephones. Thus, the telephone terminals 10 and 50 are divided into portable parts 15 and 55, which are wireless handset parts, and fixed parts 11 and 51, which are phone body parts. Each of (11, 51) is provided with touch pads (14, 17, 54, 57) for fingerprint recognition. When the user lifts up the portable part 15 of the calling party terminal 10 to make a call, the speaker of the fixed part 11 may guide the user to touch the touch pad, according to an embodiment. Then, the user places a finger on the touch pad 17 or 14 in the portable part 15 or the fixed part 11. In addition, the touch pad 17 of the portable part 15 may be positioned on the handle of the portable part 15 to automatically recognize the fingerprint of the user when the user holds the portable part 15.

If the caller's fingerprint recognition is impossible because the user does not put his or her finger on any touch pad, the call may be prohibited from being controlled under the control of the CPU 12 in the fixed part 11, but the excess of personal information In such cases, it may be possible to make a call in order to prevent exposure. Therefore, in the latter case, the identity of the caller cannot be confirmed by the telephone terminal 50 of the called party. Further, according to the embodiment, the user may be allowed to select whether or not to send his information to the telephone terminal 50 of the called party. That is, when the user lifts up the portable part 15 of the calling party terminal 10, the calling party terminal 10 will perform fingerprint recognition through the speaker of the portable part 15 or the fixed part 11. Ask the user. For example, if fingerprint recognition is desired, the first key may be pressed to press the second key. If the user does not want fingerprint recognition, a dial tone signal (ring tone) is sent so that the user can directly dial the called party's telephone number. On the contrary, when the user wants to recognize the fingerprint, the user places his or her finger on the touch pads 14 and 17 to identify the fingerprint pattern of the user and then emits a dial tone signal.

The sender's fingerprint data recognized through the touch pads 14 and 17 is input to the CPU 12 of the fixed part 11. The CPU 12 controls various functions of the calling party's telephone terminal 10 including an RF frequency control function. The CPU 12 analyzes and grasps a pattern of a fingerprint and converts it into digital data according to the present invention. The program is built in. In a typical general wired telephone network, an analog signal such as voice may be transmitted through the wired network as it is, but digital data about a fingerprint pattern generated by the CPU 12 must be digital in order to be transmitted through a normal general wired telephone network. Modulation is required. Therefore, the fingerprint pattern data generated by the CPU 12 is sent to the DSP 13 and digitally modulated. Digital Signal Processors (DSPs) are special microprocessors that digitally process signals and perform filtering, modulation and demodulation, spectral analysis, and linear prediction on digital signals. In general, in the case of a wired / wireless telephone that performs a CID function, a frequency shift keying (FSK) modulation scheme, which is relatively less affected by noise, and has a relatively simple modulation scheme, is used. Even in the present invention, the DSP 13 performs FSK modulation in order to transmit the fingerprint pattern information of the sender. However, the digital modulation scheme is merely exemplary, and other digital modulation schemes such as PSK or QAM may be used according to an embodiment.

The fingerprint pattern information of the digitally modulated sender is sent to the exchange (or base station) 30. Then, the exchange 30 requests the search by sending the digitally modulated fingerprint pattern information to the personal information database 40 in which personal information including fingerprint information is stored. As described above, the personal information database 40 stores various types of information of telephone subscribers, including fingerprint pattern information. Upon receiving the digitally modulated fingerprint pattern information from the exchange 30, the personal information database 40 searches for a subscriber that matches the fingerprint pattern. If a fingerprint pattern is found that matches the subscriber, the personal information database 40 sends information about the subscriber, for example, the subscriber's name, to the exchange 30. At this time, the exchange 30 searches whether the called party has subscribed to the caller identification service through the personal information database 40. If the telephone subscriber of the called party subscribes to the caller identification service, the switch 30 sends a 20 Hz call signal (ring signal) to the telephone terminal 50 of the called station, indicating that the call has been received. The information on the subscriber is digitally modulated and transmitted at a frequency separate from the call signal. However, if the called party's telephone subscriber has not subscribed to the caller identification service, the exchange 30 only sends a call signal to the telephone terminal 50 of the called station indicating that the call has been received.

The telephone terminal 50 of the called party rings the telephone ring when receiving the call signal from the switchboard 30, and simultaneously receives the digitally modulated personal information signal. The received personal information signal is transmitted to the DSP 53 via the CID circuit 58 and the CPU 52. Then, the DSP 53 demodulates the digitally modulated personal information signal so that the sender's personal information can be displayed on the LCD display panel 59. Therefore, the information of the actual caller, not the owner information of the calling party terminal 10, can be displayed on the LCD display panel 59 of the called party terminal 50.

So far, the configuration and operation of the present invention have been described in detail. According to the present invention, since the existing caller identification service provides caller information based on the number of the calling party's telephone terminal, the problem of the terminal owner's information being transmitted to the called party rather than the actual calling party is solved. By providing caller information, the user's information can be accurately transmitted to the called party.
