Description

Technical Field [0001] The present invention relates to an iris information registration apparatus and method,

The present invention relates to an apparatus and method for registering iris information in a communication terminal.

An authentication method for identifying a user, a terminal, or the like has evolved from using biometric information such as fingerprint and iris to using a user identification information (ID) and a password. The authentication method using the biometric information is spreading due to security and convenience.

As an example, an authentication method using biometric information may be applied to open a door. In this case, the biometric information of the people allowed to enter and exit needs to be registered in advance in the device controlling the door. In addition, when the locked state of the personal terminal is released using the biometric information, the biometric information of the user must be registered in the personal terminal.

As described above, in order to authenticate using the biometric information, it is necessary to register the complete biometric information in a personal terminal or a designated server or the like.

Activation of wired / wireless network provides convenience such as information sharing, but increases the risk of leakage of information due to hacking and the like. Especially, leakage of personal information stored in financial institutions may cause secondary damage more than imagined. For example, when the biometric information stored in the personal terminal or the designated server is leaked, there is a high possibility that the biometric information is spoiled. As a result, the user may have a feeling of refusal to store biometric information on a personal terminal, a designated server, or the like.

According to an embodiment of the present disclosure, an apparatus and method for performing authentication using only a part of biometric information in a communication terminal can be provided.

Various embodiments to be proposed below will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a schematic system structure supporting a settlement service based on partial biometric information according to various embodiments.

Referring to FIG. 1, the network 110 may provide communication services between the communication terminal 120, the registration server 130, and the payment server 140. The network 110 may have a structure in which a wired network or a wireless network or a wired / wireless network is combined.

The communication terminal 120 supports biometric information technology for acquiring biometric information such as irises and fingerprints. The communication terminal 120 extracts the partial image information from the biometric information obtained using the preset pattern, and transmits the extracted partial image information to the registration server 130 via the network 110. The predetermined pattern may be defined by a Fibonacci sequence or an isomorphic sequence.

The biometric information may be digital image information obtained by photographing fingerprints, irises, and the like. The digital image information may be a bit string and may include a predetermined number of bit values. In this case, the preset pattern can be defined by the positions of bits corresponding to partial image information to be extracted from the acquired biometric information. The pattern may be set by a pattern for extracting bits held at a constant value in the digital image information corresponding to the repeatedly acquired biometric information when the biometric information is repeatedly obtained.

Setting the pattern for extracting the bits held at a constant value as described above is intended to extract the similar partial image information even in the conversion of the environment that may affect the acquisition of the biometric information.

For example, when repeatedly photographing one iris, a plurality of digital image information corresponding to the repeated photographing will be obtained. It may be preferable to change the shooting environment at the time of the repeated shooting. For example, the photographing environment can be changed by at least one of whether infrared light is provided, whether the proximity sensor is installed, and the surrounding brightness. Compares the acquired digital image information, and confirms bit positions where a constant value is maintained in a bit string corresponding to digital image information based on the comparison result. The pattern can be set by the confirmed bit positions that are maintained at a constant value.

The communication terminal 120 may transmit to the registration server 130 predetermined identification information for specifying the extracted partial image information in addition to the extracted partial image information. The predetermined identification information may be information for identifying a user corresponding to the biometric information or the communication terminal 120. The predetermined identification information may further include information about an imaging environment at the time of iris imaging. The information about the photographing environment is information for defining the environment at the time of iris photographing. For example, the information about the photographing environment may include at least one of whether infrared light is provided, whether the proximity sensor is installed, and the surrounding brightness.

When the payment event occurs, the communication terminal 120 performs settlement processing using partial image information. The communication terminal 120 acquires the digital image information corresponding to the biometric information through the iris capturing process and extracts the partial image information from the acquired digital image information using a preset pattern. The communication terminal 120 transmits the extracted partial image information to the designated server. The designation server may be determined by an operation subject performing an authentication procedure using partial image information.

One embodiment is for the communication terminal 120 to transmit the partial image information to the designated server and perform the settlement procedure by permission of the designated server. In this case, the designated server will be the registration server 130. When it is notified from the registration server 130 that the authentication is successful, the communication terminal 120 will process the settlement according to the accepted payment request in cooperation with the payment server 140.

In another embodiment, the payment server 140 transmits the partial image information to the designated server, and the authentication procedure using the partial image information for settlement can be performed by the designated server. In this case, the designated server will be the payment server 140, and the communication terminal 120 has to transmit the partial image information to the payment server 140. The communication terminal 120 may transmit partial image information to the payment request message transmitted to the payment server 140. The payment server 140 notifies the registration server 130 of the successful authentication and processes the payment requested by the communication terminal 120.

The registration server 130 registers the partial image information transmitted by the communication terminal 120 in a designated database. The registration server 130 may register partial image information corresponding to user identification information and / or communication terminal identification information. When the communication terminal 120 provides predetermined identification information for specifying partial image information, the registration server 130 may additionally register predetermined identification information together with partial image information. The predetermined identification information may be information on a photographing environment when acquiring biometric information. The information about the photographing environment is as defined above.

The registration server 130 performs authentication using partial image information by an authentication request from the communication terminal 120 or the payment server 140. For example, the registration server 130 may check whether the partial image information provided at the time of authentication request agrees with the registered partial image information, and determine whether to permit the authentication based on the confirmation result. To this end, the communication terminal 120 or the payment server 140 preferably provides at least one of the payment identification information, the financial company identification information, and the user identification information to the registration server 140 at the time of the authentication request.

The registration server 130 transmits the authentication result to the communication terminal 120 and / or the payment server 140. The registration server 130 may transmit the authentication result to the authentication-requested object. However, the registration server 130 does not necessarily transmit the authentication result to the authentication-requested object. That is, even if the communication terminal 120 requests the authentication, the authentication result may be transmitted to the payment server 140. In addition, the payment server 140 may transmit the authentication result to the payment server 140 even if the payment server 140 requests authentication.

When the payment server 140 receives the payment request from the communication terminal 120, the payment server 140 determines whether to perform the requested payment process in consideration of the authentication result based on the partial image information. The authentication result may be reported by the communication terminal 120 or by the registration server 130. The authentication result may be reported from the registration server 130 when the communication terminal 120 requests the registration server 130 to provide the authentication result to the payment server 140. Alternatively, the payment server 140 may request the registration server 130 to authenticate and receive the result from the registration server 130.

The payment server 140 performs authentication successfully by the registration server 130, processes the requested payment, and provides the processing result to the communication terminal 120.

The payment server receives an authentication response message corresponding to the authentication request message transmitted from the registration server in operation 1214. The payment server determines whether the authentication is successful according to the received authentication response message, and performs a settlement process considering the authentication result (operation 1216).

Upon completion of the settlement processing, the settlement server forms a settlement response message corresponding to the processing result, and transmits the settlement response message to the communication terminal in step 1218.

13 is a diagram showing a configuration of a communication terminal that processes settlement using partial biometric information according to various embodiments.

Referring to FIG. 13, the communication terminal includes a control module 1310, a sensor module 1320, a communication module 1330, an input / output module 1340, and a recording module 1350. The control module 1310 includes an information extraction module 1312 and a payment processing module 1314.

The sensor module 1320 and the information extraction module 1312 support biometric information technology for acquiring biometric information such as irises and fingerprints. The sensor module 1320 may include a camera module for acquiring biometric information such as irises and fingerprints, a fingerprint scan module, and the like. For example, the camera module can output digital image information through iris photography.

The information extraction module 1312 extracts partial image information from the biometric information acquired from the sensor module 1320 using a preset pattern. The predetermined pattern may be defined by a Fibonacci sequence or an isomorphic sequence.

The biometric information may be digital image information obtained by photographing fingerprints, irises, and the like. The digital image information may be a bit string and may include a predetermined number of bit values. In this case, the preset pattern can be defined by the positions of bits corresponding to partial image information to be extracted from the acquired biometric information. The pattern may be set by a pattern for extracting bits held at a constant value in the digital image information corresponding to the repeatedly acquired biometric information when the biometric information is repeatedly obtained.

Setting the pattern for extracting the bits held at a constant value as described above is intended to extract the similar partial image information even in the conversion of the environment that may affect the acquisition of the biometric information.

For example, when repeatedly photographing one iris, a plurality of digital image information corresponding to the repeated photographing will be obtained. It may be preferable to change the shooting environment at the time of the repeated shooting. For example, the photographing environment can be changed by at least one of whether infrared light is provided, whether the proximity sensor is installed, and the surrounding brightness. The sensor module 1320 may include various sensors, such as an infrared sensor, a temperature sensor, a luminance sensor, and the like, for collecting information on the photographing environment.

The information extraction module 1312 compares the acquired digital image information and identifies bit positions where a constant value is maintained in a bit string corresponding to digital image information based on the comparison result. The pattern can be set by the confirmed bit positions that are maintained at a constant value.

The information extraction module 1312 may provide predetermined identification information for specifying the extracted partial image information in addition to the extracted partial image information. The predetermined identification information may be information for identifying a user corresponding to the biometric information or the communication terminal. The predetermined identification information may further include information about an imaging environment at the time of iris imaging. The information about the photographing environment is information for defining the environment at the time of iris photographing. For example, the information about the photographing environment may include at least one of whether infrared light is provided, whether the proximity sensor is installed, and the surrounding brightness.

The payment processing module 1314 performs a payment process using partial image information when a payment event occurs. The payment processing module 1314 receives partial image information from the information extraction module 1312 for payment processing. The extraction of the partial image information by the information extraction module 1312 can be performed by the same configuration and operation as described above.

The payment processing module 1314 may perform different operations according to two authentication procedures using partial image information.

According to one embodiment, the payment processing module 1314 may transmit the partial image information to the registration server through the communication module 1330, and may perform the payment procedure by permission of the registration server. The payment processing module 1314, when notified from the registration server that the authentication is successful, will process the settlement according to the payment request previously received in conjunction with the payment server 140 through the communication module 1330.

According to another embodiment, the payment processing module 1314 transmits the partial image information to the payment server through the communication module 1330, and allows the payment server to perform the authentication procedure using the partial image information. The payment processing module 1314 may include partial image information in the payment request message transmitted to the payment server 140 through the communication module 1330. [

The input / output module 1340 performs an operation for inputting information from outside or outputting internal information to the outside. For example, the input / output module 1340 may display a photographed iris image or output a registration result of partial image information. The input / output module 1340 provides information input for a payment request and outputs a payment processing result.

The recording module 1350 records the information generated and collected at the time of authentication and payment processing using the partial image information, and performs an operation to provide the generated information when necessary. For example, the recording module 1350 can record digital image information corresponding to the acquired biometric information, partial image information, information on a pattern to be used for extracting the partial image information, information on the photographing environment, settlement related information, .
