The present invention relates to an electronic device and, more particularly, to an electronic device that is capable of easily accessing a target service or a target external device through multi-factor authentication.
To use a particular service with an electronic device, authentication information is required to use the corresponding service.
Recently, a variety of authentication methods, such as authentication via iris recognition, face recognition or fingerprint recognition, have been employed in mobile terminals.
In the case where iris recognition is used, an iris recognition rate is reduced in the presence of direct sunlight.
In addition, in the case where face recognition is used, a face recognition rate is reduced in a dark place.
Meanwhile, in order to execute services with an electronic device, different types of authentication information are required for the respective service and a user needs to perform authentication each time.
The present invention provides an electronic device capable of easily accessing a target service or target external device through multi-factor authentication.
The present invention also provides an electronic device that is capable of being used to access a variety of services or an external device with a final security level score calculated through multi-factor authentication.
In one general aspect of the present invention, the above and other objects can be accomplished by the provision of an electronic device including: an input unit provided with buttons; a plurality of sensors; and a controller configured to activate at least some of the plurality of sensors based on a received activation signal, generate authentication information based on at least one of the activated sensors, calculate a final security level score based on a security level score corresponding to the at least one authentication information, and determine whether a target service or a target external device is accessible, based on the calculated final security level score.
In another general aspect of the present invention, the above and other objects can be accomplished by the provision of an electronic device including: an input unit provided with buttons; a plurality of sensors; and a controller configured to, when a current final security level score is smaller than a first security level score required by a target service or a target external device, activate at least some of inactive sensors, generate at least one authentication information based on the activated sensors, calculate a second final security level score using the at least one authentication information, and determine whether the target service or the target external device is accessible, based on the calculated second final security level score.
An electronic device according to an embodiment of the present invention includes: an input unit provided with buttons; a plurality of sensors; and a controller configured to activate at least some of the plurality of sensors based on a received activation signal, generate authentication information based on at least one of the activated sensors, calculate a final security level score based on a security level score corresponding to the at least one authentication information, and determine whether a target service or a target external device is accessible, based on the calculated final security level score. Accordingly, it is possible to easily access the target service or the target external device through multi-factor authentication.
In this case, the activation signal may include at least one of an input signal from the input unit, a sensing signal from a touch sensor, a GPS sensor, or an inertial sensor among the plurality of sensors, or a sensing signal from a microphone among the plurality of sensors. Accordingly, at least some of the plurality of sensors may be activated to thereby easily access a target service or a target external device through multi-factor authentication.
In addition, since a final security level score calculated through multi-factor authentication is used to access a variety of services or an external device, an authentication process may become easy and simple.
Meanwhile, in response to occurrence of an event, a control operation is performed so as to activate at least one of the plurality of sensors or generate authentication information based on a sensing signal from the activated sensor. Accordingly, while supply power is used efficiently, it is possible to easily access a target service or a target external device through multi-factor authentication.
Meanwhile, as a security level score for authentication information is changed based on time lapse or occurrence of an event, a final security level score may be updated in real time. Thus, it is possible to easily access a target service or a target external device through multi-factor authentication.
Meanwhile, when a calculated final security level score is smaller than a first security level score required by a target service or a target external device, a control operation is performed to output a message for requesting additional authentication information, thereby inducing the additional authentication.
Meanwhile, a control operation is performed to reduce a security level score for authentication information after a predetermined time or sequentially over time so as to update the final security level score in real time.
Meanwhile, if received at least one authentication information does not coincide with authentication information stored in a memory, a control action may be performed to reset a security level score for the corresponding authentication information or reset a calculated final security level score, thereby enhancing security of the authentication information.
Meanwhile, an image captured by a camera out of a plurality of sensors is transmitted to a predetermined external device at a time of resetting a security level score or a final security level score, and accordingly, a designated device or a designated user is able to immediately recognize an authentication error occurred due to an access attempt by an unauthorized user.
Meanwhile, an electronic device according to another embodiment of the present invention includes: an input unit provided with buttons; a plurality of sensors; and a controller configured to, when a current final security level score is smaller than a first security level score required by a target service or a target external device, activate at least some of the plurality of sensors based on a received activation signal, generate authentication information based on at least one of the activated sensors, calculate a final security level score based on a security level score corresponding to the at least one authentication information, and determine whether a target service or a target external device is accessible, based on the calculated final security level score. Accordingly, it is possible to easily access the target service or the target external device through multi-factor authentication.
The embodiments will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein:
Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
In the following description, with respect to constituent elements used in the following description, the suffixes “module” and “unit” are used or combined with each other only in consideration of ease in the preparation of the specification, and do not have or serve as different meanings. Accordingly, the suffixes “module” and “unit” may be interchanged with each other.
Referring to the drawings, an authentication system 10 in
When executing a Web login service, a payment service, and the like, the electronic device 100 may transmit authentication information, a data transmission request, and the like to an external server 300. Based on the authentication information, the external service 300 may transmit data to the electronic device 100 in response to the data transmission request. Accordingly, the electronic device 100 may display a screen related to the corresponding service based on the received data.
Meanwhile, in the case of executing the web login service, the payment service, and the like, the electronic device 100 according to an embodiment of the present invention may activate at least some of a plurality of sensors based on an activation signal, generate authentication information based on activated sensors, generate at least one authentication information based on at least some of multiple sensors in the electronic device 100, calculate a final security level score based on a security level score corresponding to the at least one authentication information, and determine, based on the calculated final security level score, whether a target service or a target external device is accessible.
Meanwhile, a security level score may be a matching score. The matching score may be information related to a degree of matching (a similarity level) between user information and authentication information.
In this case, the activation signal may include an input signal from the input unit 130, a sensing signal from a touch sensor, a GPS sensor, or an inertial sensor among the plurality of sensors, and a voice signal from a microphone among the plurality of sensors.
Meanwhile, the activation signal may include an input signal for executing a first service.
Specifically, the electronic device 100 may receive security level information required for the Web login service or the payment service, and compare a calculated final security level score with a received security level score required by the web login service or the payment service. When the calculated security level score is greater than the required security level score, the electronic device 100 may determine that the web login service or the payment service is accessible.
If a particular application (e.g., a banking application) is executed in the electronic device, an activation signal may be output.
When it is determined that the target service or the target external device is accessible, the electronic device 100 may transmit a data transmission request to the server 300. In response to the data transmission request, the server 300 may transmit data to the electronic device 100. Accordingly, the electronic device 100 may display a screen related to a corresponding service based on the received data.
In this manner, it is possible to easily access a target service or a target external device through multi-factor authentication.
In addition, since a variety of services or external devices are able to be accessed using a final security level score calculated through multi-factor authentication, it is possible to make authentication easy and convenient.
In another example, the electronic device 100 may transmit a calculated final security level score to the server 300, and the server 300 determines whether a web login service or a payment service is accessible. When the web login service or the payment service is accessible, the server 300 may transmit data to the electronic device 100. Accordingly, the electronic device 100 may display a screen related to a corresponding service based on the received data.
Meanwhile, the server 300 may be any of servers provided by various service providers or a server provided by a manufacturer of the electronic device 100.
Meanwhile, the electronic device 100 may output a message for requesting additional authentication, when a calculated final security level score is smaller than a first security level score required by a target service or a target external device. Accordingly, additional authentication may be performed.
Meanwhile, the electronic device 100 according to an embodiment of the present invention may be a device which needs to perform authentication and includes having a plurality of sensors for acquiring authentication information.
The plurality of sensors may include at least two of a camera, a fingerprint sensor, a microphone, an inertial sensor, a touch sensor, or an illumination sensor.

Referring to the drawing, the electronic device 100 may include a communication unit 110, an input unit 130, a sensing unit 140, a memory 160, a controller 170, a display 180, an audio output unit 185, and a power supply 190.
When these components are actually implemented, two or more components may be combined into one or one component may be divided into two or more.
The communication unit 110 may provide an interface for communication with an external device. To this end, the communication unit 110 may include at least one of a mobile communication module (not shown), a wireless Internet module (not shown), a short-range communication module (not shown), or a GPS module (not shown).
For example, the communication unit 110 may perform IR communication, Bluetooth communication, Wi-Fi communication, or the like to exchange data with a paired external electronic device (e.g., a mobile terminal or a vehicle) or transmit data.
The input unit 130 may include a physical button, a soft button, and the like for initializing the electronic device or inputting an operation.
The sensing unit 140 may include a plurality of sensors.
The plurality of sensors may include a camera 195, a fingerprint sensor 142, a microphone 123, an inertial sensor 145, a touch sensor 146 implemented as a touch pad or a touch screen, an illumination sensor 148, and the like.
The camera 195 may be a concept including a camera for acquiring a visible-light image or an IR camera for acquiring an IR band image.
The fingerprint sensor 142 is a sensor for acquiring a fingerprint image. The fingerprint sensor 142 may be disposed in a particular button of the input unit 130 or may be embedded in part of the front frame or the rear frame of the electronic device 100.
The microphone 123 may be disposed to sense an audio signal.
The inertial sensor 145 may include an accelerometer, a gyro sensor, a gravity sensor, and the like. For example, the accelerometer, the gyro sensor, the gravity sensor, and the like may include a six-component sensor.
The inertial sensor 145 may output motion information of the electronic device 100, for example, movement information (acceleration information, angular velocity information) or location information with reference to X, Y, and Z axes.
The illumination sensor 148 may sense ambient illumination of the electronic device 100, and output a sensed signal.
In addition, the sensing unit 140 may further include a variety of sensors for acquiring a user's biometric information.
For example, the sensing unit 140 may further include a blood pressure sensor, a brainwave sensor, and the like.
The memory 160 may store a program for processing or controlling operations of a controller 170 in the electronic device 100, or may implement a function of temporarily storing input/output data.
The controller 170 may control operation of each unit in the electronic device 100 so as to control overall operations of the electronic device 100.
The display 180 may display diverse information of an image, and, to this end, the display 180 may include a Liquid Crystal Display (LCD) panel, an organic light emitting panel, a Light Emitting Diode (LED) panel, or the like.
The audio output unit 185 may output an audio signal processed by the controller 170 in the electronic device 100.
Alternatively, the audio output unit 185 may output guidance information regarding operation of the electronic device 100 in the form of an audio signal.
Under the control of the controller 170, the power supply 190 may supply power required to operate each component.
In particular, the power supply 190 may include a battery (not shown) for storing and outputting direct current (DC) power.
Referring to the drawing, the controller 170 may receive a sensing signal from the sensing unit 140, and generate authentication information based on the received sensing signal.
To this end, the controller 170 may include an event manager 305, an authentication information generator 310, a security level score calculator 320, a final security level score calculator 330, and an access determiner 340.
The event manager 305 may manage an event that has occurred.
In one example, when the electronic device 100 is moved in a standby mode, an event of finishing the standby mode and entering the operation mode may occur.
In this case, the event manager 305 may trigger an operation mode entrance event based on a motion signal from the sensing unit 140.
In another example, if a first button of the input unit 130 is operated while the electronic device 100 is in the operation mode, the event manager 305 may cause an event for providing a first service by a first button to occur. For example, the first button may be a home button, and providing a first service may be providing a home screen service.
In yet another example, if an audio signal is collected through the microphone 123 of the sensing unit 140 while the electronic device 100 is in the standby mode or the operation mode, an event corresponding to the collected audio signal may occur.
For example, when sound including a key word or a natural language, such as “weather”, “traffic information”, “play music”, and “payment”, is collected through the microphone 123, the event manager 305 may trigger a weather information provision event, a traffic information provision event, a music provision event, a payment event, and the like.
In yet another example, when a final security level score of the electronic device 100 is smaller than a security level score required for a target service, the event manager 305 may trigger an event for security authentication.
Specifically, the event manager 305 may trigger an event for activating a sensor remaining inactive out of a plurality of sensors in the sensing unit 140. Such an event may be referred to as a trigger event.
Meanwhile, when a sensing value of a first sensor being activated among the plurality of sensors is equal to or smaller than a first reference value, the event manager 305 may activate at least one of other sensors, except the first sensor.
To this end, the event manager 305 may output an activation signal Tri to the sensing unit 140.
For example, when a sensing value of the illumination sensor 148 being activated is equal to or smaller than the first reference value, the ambient illumination is dark. Thus, even though a camera is activated, it is not possible to acquire an image with good quality.
Thus, the event manager 305 may perform control such that the microphone 123, the fingerprint sensor 142, or the touch sensor 146 is activated.
Meanwhile, when a sensing value of the first sensor being activated among the plurality of sensors is equal to or greater than a second reference value or when an input signal is received from the input unit 130, the event manager 305 may activate at least one of other sensors, except the first sensor.
For example, when a peak level of sound collected through the microphone 123 being activated is equal to or greater than the second reference value due to loud ambient sound, it is not easy to extract a user's voice.
Thus, the event manager 305 may perform control such that the camera 195, the fingerprint sensor 142, or the touch sensor 146 is activated.
Meanwhile, the event manager 305 may output a trigger signal Tri to the sensing unit 140 based on an input activation signal.
The activation signal may be an input signal from the input unit 130, a sensing signal from the touch sensor 146 or the inertial sensor 145 in the sensing unit 140, or a voice signal from the microphone 123.
The sensing unit 140 may activate an inactive sensor based on the trigger signal Tri.
Meanwhile, the event manager 305 may output the trigger signal Tri to the access determiner 340.
Accordingly, the access determiner 340 may compare a final security level score of the current time and a security level score required by a target service, and determine whether the target service is accessible.
Meanwhile, when a sensing value of the first sensor being activated among the plurality of sensors is equal to or greater than the second reference value or when an input signal is received from the input unit 130, the event manager 305 may perform control such that at least one of other sensors, except for the first sensor, is activated.
Meanwhile, when a calculated final security level score is smaller than a first security level score required by a target service or a target external device, the event manager 305 may output a message for requesting additional authentication information.
The authentication information generator 310 may generate authentication information based on a sensing signal from each of the multiple sensors in the sensing unit 140.
In response to occurrence of an event, the authentication information generator 310 may generate authentication information based on a sensing signal from a pre-activated sensor.
For example, the authentication information generator 310 may generate iris authentication information based on an image captured by the camera 195.
In another example, the authentication information generator 310 may generate face authentication information based on an image captured by the camera 195.
Meanwhile, the authentication information generator 310 may generate fingerprint authentication information based on an image captured by the fingerprint sensor 142.
Meanwhile, the authentication information generator 310 may generate glottal authentication information or voice recognition information based on a user's voice acquired through the microphone 123.
Meanwhile, the authentication information generator 310 may generate usage pattern authentication information based on a sensing signal from the touch sensor 146.
Meanwhile, the authentication information generator 310 may generate location authentication information based on a sensing signal acquired through the inertial sensor 145 or a GPS sensor (not shown).
Meanwhile, the authentication information generator 310 may generate illumination authentication information based on a sensing signal acquired through the illumination sensor 148.
The security level score calculator 320 may calculate a security level score for each authentication information generated by the authentication information generator 310.
Meanwhile, the security level score for each authentication information generated by the authentication generator 310 may be pre-stored in the memory 160.
For example, a security level score for iris authentication information may be set to Level 9, a security level score for fingerprint authentication information may be set to Level 5, a security level score for face authentication information may be set to Level 3, a security level score for voice authentication information may be set to Level 2, a security level score for usage pattern authentication information may be set to Level 1, and a security level score for location authentication information may be set to Level 0.5. These security level scores may be stored in the memory 160.
As such, in an embodiment of the present invention, a security level score may be set differently depending on a type of authentication information.
Meanwhile, the security level score calculator 320 may perform control such that a security level score for authentication information is changed based on time lapse or occurrence of an event.
Meanwhile, after generating authentication information, the security level score calculator 320 may reduce a security level score for the authentication information over time.
In particular, after receiving authentication information, the security level score calculator 320 may reduce a security level score for the authentication information after a predetermined time or sequentially over time.
In one example, the security level score calculator 320 may first set a security level score for iris authentication information to Level 9, and reduce the security level to Level 7 after 5 minutes and then to Level 5 after 10 minutes.
In another example, the security level score calculator 320 may first set a security level score for fingerprint authentication information to Level 5, and reduce the security level score to Level 4 after 5 minutes and then to Level 3 after 10 minutes.
As such, depending on a type of authentication information, a security level score for the authentication information may be reduce by a different degree over time.
Meanwhile, based on a sensing signal generated by an activated sensor, the security level score calculator 320 may generate corresponding authentication information.
The final security level score calculator 330 may calculate a final security level score based on authentication information received from the security level score calculator 320.
The final security level score calculator 330 may calculate a final security level score based on a plurality of authentication information received from the security level score calculators 320.
Meanwhile, depending on a situation, the final security level score calculator 330 may calculate a final security level score based on one authentication information received from the security level score calculator 320.
In one example, the final security level score calculator 330 may calculate a final security level score by summing up a plurality of authentication information received from the security level score calculator 320.
In another example, the final security level score calculator 330 may calculate a final security level score by assigning different weights to the plurality of authentication information received from the security level score calculator 320.
For instance, in the case where fingerprint authentication information occurs more frequently than iris authentication information, the final security level score calculator 330 may determine that a user usually use the fingerprint authentication information. Then, the final security level score calculator 330 may assign a higher weight to the fingerprint authentication information than the iris authentication information, and calculate a final security level score by summing all the authentication information according to the assigned weight.
Meanwhile, the final security level score calculator 330 may perform control such that a final security level score is changed based on time lapse or occurrence of an event.
Meanwhile, after generating a final security level score, the final security level score calculator 330 may reduce the final security level score over time.
In particular, after calculating a final security level score, the final security level score calculator 330 may reduce the final security level score after a predetermined time or sequentially over time.
Based on a final security level score calculated by the final security level score calculator 330, the access determiner 340 may determine whether a target service or a target external device is accessible.
For example, the access determiner 340 may receive security level information required for a web login service or a payment service, and compare a calculated final security level score with a received security level score required by the web login service or the payment service. When the calculated final security level score is greater than the required security level score, the access determiner 340 may determine that the web login service or the payment service is accessible.
When it is determined that a target service or a target external device is accessible, the access determiner 340 may transmit a data transmission request to the server 300. In response to the data transmission request, the server 300 may transmit data to the electronic device 100.
Accordingly, the electronic device 100 may display a screen related to a corresponding service based on the received data.
Accordingly, it is possible to easily access the target service or the target external device through multi-factor authentication.
Meanwhile, when the calculated final security level score is smaller than the security level score of the web login service or the payment service, the access determiner 340 may determine that additional authentication is necessary for the web login service or the payment service, and transmit information about a request for additional authentication to the event manager 305 or the sensing unit 140.
Accordingly, it is possible to activate a sensor remaining inactive in the sensing unit 140.
Meanwhile, when the calculated final security level score is smaller than a first security level score required by a target service or a target external device, the controller 170 may output a message for requesting additional authentication information.
Meanwhile, when the calculated final security level score is smaller than a first security level score required by the target service or the target external device, the controller 170 may activate a first sensor remaining inactive in a plurality of sensors and generate additional authentication information based on the activated first sensor. Further based on the additional authentication information, the controller 170 may calculate a second final security level score. Based on the second final security level score, the controller 170 may determine whether the target service or the target external device is accessible.
Meanwhile, when the calculated final security level score is smaller than the first security level score required by the target service or the target external device, the controller 170 may output indicator items to guide selection of a plurality of authentication information. If one of the indicator items is selected, the controller 170 may activate a sensor or authentication information corresponding to the selected indicator item. Based on the activated sensor or the activated authentication information, the controller 170 may generate additional authentication information. Further based on the additional authentication information, the controller 170 may calculate a second final security level score. Based on the second final security level score, the controller 170 may determine whether the target service or the target external device is accessible.
Meanwhile, when the second final security level score is equal to or greater than the first security level score required by the target service or the target external device, the controller 170 may access to the target service or the target external device.
Meanwhile, during the access to the target service or the target external device, the controller 170 may receive relevant data from a service provider or an external device, and perform control such that display a screen related to the target service or the target external device.
Meanwhile, when the calculated final security level score is equal to or greater than the first security level score required by the target service or the target external device, the controller 170 may access to the target service or the target external device.
During the access to the target service or the target external device, the controller 170 may receive relevant data from a service provider or an external device and display a screen related to the target service or the target external device.
Meanwhile, when the calculated final security level score is equal to or greater than the first security level score required by the target service or the target external device, the controller 170 may transmit a data transmission request to a provider of the target service or to the target external device or the provider or the target external device is controlled to transmit authentication data. Then the controller 170 may receive relevant data from the provider or the target external device and display a screen related to the target service or the target external device.
Meanwhile, the controller 170 may perform control such that a security level score for authentication information is reduced after a predetermined time or sequentially over time.
Meanwhile, the controller 170 may compare received at least one authentication information received with authentication information stored in the memory 160. When the received at least authentication information coincides with the authentication information stored in the memory 160, the controller 170 may calculate a final security level score based on the corresponding authentication information. Based on the calculated final security level score, the controller 170 may determine whether the target service or the target external device is accessible.
Meanwhile, the controller 170 may compare received at least one authentication information and authentication information stored in the memory 160. When the received at least one authentication information coincides with the authentication information stored in the memory 160, the controller 170 may perform control such that a security level score of the corresponding authentication information is reset or a calculated final security level score is reset.
Meanwhile, when resetting a security level score or a final security level score, the controller 170 may perform control such that an image captured by a camera among a plurality of sensors is transmitted to a predetermined external device.
Meanwhile, based on the calculated final security level score, the controller 170 may perform control such that recommendation information about an executable service or a remote controllable external device is provided.
Meanwhile, when an input signal is received from the input unit 130, when a sensing signal from an inertial sensor or a sensing signal from a touch sensor is equal to or greater than a first reference value, when a sensing signal from an illumination sensor is equal to or smaller than a second reference value, or when a level of sound output from a microphone 123 is equal to or greater than a third reference value, the controller 170 may generate a trigger signal.

The security level score calculator 320 in the controller 170 may calculate a security level score for each authentication information generated by the authentication information generator 310.
The security level score calculator 320 may calculate a security level score for each authentication information generated by the authentication information generator 310.
Meanwhile, a security level score for each authentication information generated by the authentication information generator 310 may be pre-stored in the memory 160.
Meanwhile, in an embodiment of the present invention, a security level score may be set differently depending on a type of authentication information.
Meanwhile, the security level score calculator 320 may perform control such that a security level score for authentication information is changed based on time lapse or occurrence of an event.
Meanwhile, after generating authentication information, the security level score calculator 320 may reduce a security level score for the authentication information over time.
In particular, after receiving authentication information, the security level score calculator 320 may reduce a security level score for the authentication information after a predetermined time or sequentially over time.
In one example, the security level score calculator 320 may first set a security level score for iris authentication information to level 9, and reduce to level 7 after 5 minutes and then to level 5 after 10 minutes.
In another example, the security level score calculator 320 may first set a security level score for fingerprint authentication information to Level 5, and reduce to Level 4 after 5 minutes and to Level 3 after 10 minutes.
As such, depending on a type of authentication information, a security level score for the authentication information may be reduced by a different degree over time.
A final level score calculator 330 in the controller 170 may calculate a final security level score based on authentication information received from the security level score calculator 320.

Next, based on the final security level score, the controller 170 of the electronic device 100 may determine whether a particular service or a particular external device is accessible in S730. When the particular service or the particular external device is accessible, the controller 170 may perform an access to the particular service or the particular external device in S740.
Based on the final security level score calculated by the final security level score calculator 330, the access determiner 340 may determine whether the target service or the target external device is accessible.
For example, the access determiner 340 may receive security level information required by a web login service or a payment service, and compare a calculated final security level score with a received security level score required by the web login service or the payment service. When the calculated final security level score is greater than the required security level score, the access determiner 340 may determine that the web login service or the payment service is accessible.

As shown in
Meanwhile, when a security level score necessary for a payment service is Level 9, the controller 670 of the mobile terminal 600 may determine that the service is not executable, because the final security level score is Level 6. In this case, the controller 670 may perform control such that an additional authentication message is output or an inactive sensor is activated.
For example, the controller 670 of the mobile terminal 600 may activate the camera 695.
Accordingly, the controller 670 of the mobile terminal 600 may acquire an image from the camera 695, especially the front camera 695a, and acquire authentication information based on the image.
