The present disclosure relates to an electronic device that processes an image signal obtained through an image sensor.
Along with recent technological developments, electronic devices have been developed to execute various functions and provide various services to users through executable functions. For example, an electronic device may provide a payment service, a financial service, etc., through various executable functions.
However, as electronic devices provide services, such as a payment service, a financial service, etc., requiring personal information that should not be exposed to other people, etc., the importance personal information security in electronic devices has been increasing. As such, in line with the increasing importance of security in electronic devices, various security methods such as limiting use by another user have been developed.
For security of an electronic device, user's biological characteristics (e.g., a fingerprint, a retina, an iris, a voice, etc.) may be used and various security methods using a user's biological characteristics have been developed.
Recently, a security method using an iris among the user's biological characteristics has been developed and used. A person's iris differs in shape from person to person, and especially, has a low risk of a forgery and hardly ever changes during a lifetime, such that an iris-based security method has been increasingly used.
Information about the iris of the user is information for identifying the user, and has a high importance of security. Thus, the electronic device may allow an access to the information about the iris of the user or a control over a camera module for obtaining the information about the iris of the user, only through a specific application. Consequently, the security of the information about the iris of the user may be maintained, but utilization of the information about the iris of the user may be degraded.

According to various embodiments of the present disclosure, the camera module 520 may be included in the electronic device 101 as shown in
According to various embodiments of the present disclosure, the camera module 520 may include a lens 521, an infrared filter 522, an image sensor 523, and an IRED 524. The lens 521 may transmit light reflected from an object. The processor 510 may adjust a focus of the lens 521 to photograph the object. For example, to photograph an iris, the processor 510 may adjust the focus of the lens 521 according to a user input or an algorithm for iris photographing.
The infrared filter 522 may transmit light in an infrared wavelength band of light that is reflected from the object after being incident through the lens 521. When the infrared filter 522 is turned on, the image sensor 523 may receive light in the infrared wavelength band, which has passed through the infrared filter 522, convert the received light in the infrared wavelength band into an image signal, and output a generated infrared light image. The processor 510 may output the infrared light image output from the image sensor 523 through the display 160.
The IRED 524 may irradiate the light in the infrared wavelength band. The processor 510 may control the IRED 524 to irradiate the light in the infrared wavelength band to the user, when capturing an iris of the user. The processor 510 may control a light irradiation direction or a pulse pattern of irradiation light of the IRED 524 such that the light in the infrared wavelength band is irradiated to a face or both eyes of the user.
The image sensor 523 may receive the light incident through the lens 521 and output a visible light image generated by converting the received light into an image signal. When the infrared filter 522 is turned on, the image sensor 523 may receive light in the infrared wavelength band, which has passed through the infrared filter 522 and may output an infrared light image generated by converting the received light in the infrared wavelength band into an image signal.
According to various embodiments of the present disclosure, the processor 510 may execute a first application. The processor 510 may execute the first application selected by a user's input from among a plurality of applications installed in the electronic device 101, and display an execution screen of the first application through the display.
According to various embodiments of the present disclosure, the processor 510 may identify a security level of the first application. A security level of each of a plurality of distributed applications may be set or changed by a manufacturer of the electronic device 101, a distributor of an application, an external authentication organization, etc. The processor 510 may identify the security level of the first application in execution or installation of the first application.
Security level information indicating a security level of each of the plurality of applications may be stored in an external electronic device that manages a security level of an application, or the memory 540. The security level information may be stored in association with identification information (e.g., signing information, etc.) used to identify each of the plurality of applications. The security level information may be stored in the security region that is set in the external electronic device or the memory 540. The processor 510 may identify the security level of the first application, based on the security level information stored in the external server or the memory 540.
According to various embodiments of the present disclosure, a security level may be set for each of a plurality of functions provided in an application. A security level of each of the plurality of functions provided in the application may be set or changed by the manufacturer of the electronic device 101, the distributor of the application, the external authentication organization, etc.
Thus, a different security level may be applied to an identical application according to an execution function. Information indicating the security level of each of the plurality of functions provided in the application may be included in the security level information, and the processor 510 may identify the security level for each of the plurality of functions provided in the application, based on the security level information.
According to various embodiments of the present disclosure, the processor 510 may include a first processor operated in a security region and a second processor operated in a non-security region. The first processor may perform a security-required operation and may be isolated from external access and protected against non-allowed control of the second processor over the non-security region. The first processor and the second processor may be physically separate processors, and the processor 510 may be logically divided into the first processor and the second processor.
According to various embodiments of the present disclosure, the first processor included in the processor 510 may perform an operation of identifying the security level of the first application. To prevent leakage, change, deletion, etc., of security levels of applications, the first processor operated in the security region may identify a security level of an application.
For example, the second processor included in the processor 510 may request the first processor to identify the security level of the first application. The first processor having received the request for identifying the security level may identify the security level of the first application. The first processor may deliver a result of identifying the security level of the first application to the second processor.
For example, the first processor may identify the security level of the first application based on information stored in the memory 540, when the security level information is stored in the memory 540. To reinforce security, the security level information may be stored in the security region that is set in the memory 540. Thus, the first processor operated as the security region may access the security level information, and an access of the second processor operated as the non-security region to the security level information may be prevented.
According to various embodiments of the present disclosure, when the security level information is stored in the external electronic device that manages security levels of applications, the first processor may request the external electronic device to identify the security level of the first application through the communication module 530. The first processor may identify the security level of the first application based on a response received from the external electronic device through the communication module 530.
According to various embodiments of the present disclosure, it has been described above that the first processor operated in the security region identifies the security level of the application, but the present disclosure is not limited thereto such that the second processor operated in the non-security region may also identify the security level of the application according to user's settings, etc. A method of identifying a security level of a function provided in an application is the same as the above-described method of identifying a security level of an application and thus will not be described separately.
According to various embodiments of the present disclosure, the processor 510 may assign an authority for controlling at least one of the infrared filter 522, the image sensor 523, and the IRED 524 to the first application based on the identified security level of the first application. For example, the processor 510 may identify an authority corresponding to the identified security level of the first application according to a preset criterion and assign the identified authority to the first application.
The preset criterion may be set such that an authority of a higher level may be assigned for a higher security level. For a higher level of the authority, a controllable range for at least one of the infrared filter 522, the image sensor 523, and the IRED 524 may be extended. The preset criterion may be set in various ways by a manufacturer, a user, etc., of the electronic device 101.
For example, the processor 510 may assign a first authority for controlling the image sensor 523 to the first application, when identifying the security level of the first application as a first security level. Herein, the first security level may be the lowest security level. In this case, the processor 510 may not be able to control the infrared filter 522 and/or the IRED 524, and may control the image sensor 523 through the first application assigned with the first authority. As such, the processor 510 may not allow the first application to use the infrared filter 522 and/or the IRED 524, but may allow the first application to use the image sensor 523 for generation of a visible light image, when identifying the security level of the first application as the first security level.
For example, the processor 510 may assign a second authority for controlling the image sensor 523 and the infrared filter 522 to the first application, when identifying the security level of the first application as a second security level. Herein, the second security level may be higher than the first security level. In this case, the processor 510 may not control the IRED 524 and may control the image sensor 523 and the infrared filter 522, through the first application assigned with the second authority. As such, the processor 510 may not allow the first application to use the IRED 524, but may allow the first application to use the image sensor 523 and the infrared filter 522, when identifying the security level of the first application as the first security level.
For example, the processor 510 may assign a third authority for controlling on/off operations of the image sensor 523, the infrared filter 522, and the IRED 524, when identifying the security level of the first application as a third security level. Herein, the third security level may be higher than the second security level. In this case, the processor 510 may not control an operation other than the on/off operation of the IRED 524, and may control the on/off operations of the image sensor 523, the infrared filter 522, and the IRED 524. As such, the processor 510 may allow the first application to use the image sensor 523 and the infrared filter 522 while allowing the first application to control the on/off operation of the IRED 524, when identifying the security level of the first application as the third security level.
For example, the processor 510 may assign a fourth authority for controlling operations of the image sensor 523, the infrared filter 522, and the IRED 524, when identifying the security level of the first application as a fourth security level. Herein, the fourth security level may be higher than the third security level. In this case, the processor 510 may control operations of the image sensor 523, the infrared filter 522, and the IRED 524. For example, the processor 510 may control the IRED 524 such that an irradiation direction of infrared light and/or a pulse pattern of infrared light are a selected irradiation direction and/or a selected pulse pattern. As such, the processor 510 may allow the first application to use the image sensor 523 and the infrared filter 522 while allowing the first application to control an operation of the IRED 524, when identifying the security level of the first application as the fourth security level.
The above-described method of assigning an authority based on a security level is merely intended for a description, and the present disclosure is not limited thereto such that a security level and an authority assigned based on the security level may set variously. In this way, the processor 510 may stepwise assign an authority of a higher level to an application of a higher security level.
According to various embodiments of the present disclosure, the processor 510 may determine whether to process a control command for controlling at least one of the infrared filter 522, the image sensor 523, and the IRED 524 through the first application, based on the authority assigned to the first application.
According to various embodiments of the present disclosure, the processor 510 may identify whether a control command for controlling at least one of the infrared filter 522, the image sensor 523, and the IRED 524 falls within an authority range assigned to the first application. The processor 510 may control the at least one of the infrared filter 522, the image sensor 523, and the IRED 524 to perform an operation corresponding to the control command, when the control command falls within the authority range assigned to the first application.
According to various embodiments of the present disclosure, the processor 510 may not perform the operation corresponding to the control command, when the control command deviates from the authority range assigned to the first application. In this case, the processor 510 may provide a notification indicating that the operation corresponding to the control command may not be performed.
For example, when the first authority is assigned to the first application, the processor 510 may determine that the control command for controlling the image sensor 523 through the first application falls within a range of the first authority. Thus, the processor 510 may perform a control operation of the image sensor 523 according to the control command.
For example, the processor 510 may determine that the control command for controlling the IRED 522 through the first application deviates from the range of the first authority. Thus, the processor 510 may provide a notification indicating that the control operation of the IRED 522 may not be performed, without performing the control operation of the IRED 522 according to the control command.
According to various embodiments of the present disclosure, the processor 510 may manage an image signal or data provided to the first application, based on the authority assigned to the first application. For example, the processor 510 may determine whether to provide an image signal obtained through the image sensor 523 of the camera module 520 to the first application, based on the authority assigned to the first application.
The processor 510 may control the image signal to be provided to the first application when determining that the providing of the image signal falls within the authority range assigned to the first application. On the other hand, the processor 510 may control the image signal not to be provided to the first application, when determining that the providing of the image signal deviates from the authority range assigned to the first application.
For example, when the first authority is assigned to the first application, the processor 510 may control an image signal, which is obtained by converting light that passes through the IRED 522 after being obtained from the image sensor 523 of the camera module 520, not to be provided to the first application assigned with the first authority. The processor 510 may control an image signal of an iris, which is obtained from the image sensor 523, not to be provided to the first application assigned with the first authority.
For example, when the second authority is assigned to the first application, the processor 510 may control an image signal of an iris, which is obtained from the image sensor 523, not to be provided to the first application assigned with the second authority.
For example, when the third authority is assigned to the first application, the processor 510 may control an image signal of an iris, which is obtained from the image sensor 523, not to be provided to the first application assigned with the third authority, and control a result of iris recognition performed using the image signal of the iris to be provided to the first application assigned with the third authority.
The processor 510 may obtain the image signal of the iris from the image sensor 523 based on an iris recognition command through the first application. The processor 510 may perform iris recognition by using the image signal of the iris through a second application assigned with an authority for iris recognition, without delivering the obtained image signal of the iris directly to the first application. The processor 510 may control the result of iris recognition performed using the second application to be provided to the first application assigned with the third authority.
For example, when the fourth authority is assigned to the first application, the processor 510 may control an image signal of an iris, which is obtained from the image sensor 523, to be provided to the first application assigned with the fourth authority.
The processor 510 may obtain the image signal of the iris from the image sensor 523 based on an iris recognition command through the first application. The processor 510 may control the obtained image signal of the iris to be provided to the first application assigned with the fourth authority.
As such, the processor 510 may determine whether to provide an image signal obtained through the image sensor 523 to the first application as well as whether to process a control command for a component included in the camera module 520, based on the authority assigned to the first application.
According to various embodiments of the present disclosure, the processor 510 may identify a security level of a first function among a plurality of functions provided in the first application. For example, the processor 510 may identify the security level of the first function among the plurality of functions when the first function is executed in response to a user's request, etc. The processor 510 may also identify a security level of each of the plurality of functions provided in the first application, including the first function, in installation of the first application.
According to various embodiments of the present disclosure, the processor 510 may determine whether to limit the authority assigned to the first application to execute the first function through the first application, based on the identified security level of the first function. A security level of each of the plurality of functions provided in the first application may differ, such that the processor 510 may identify the security level of the first function and determine whether to limit the authority assigned to the first application based on the identified security level.
For example, when the security level of the first function is lower than the security level of the first application, the processor 510 may determine to limit at least a part of the authority assigned to the first application based on the security level of the first function. When the security level of the first function is lower than the security level of the first application, the authority assigned based on the security level of the first application may not be entirely used, and thus the processor 510 may limit the assigned authority.
For example, when the security level of the first function is the same as the security level of the first application, the processor 510 may not limit the assigned authority.
When the security level of the first function is higher than the security level of the first application, the processor 510 may assign an additional authority based on the security level of the first function. Thus, the processor 510 may enable control based on the assigned additional authority in execution of the first function through the first application.

In this case, the processor 610 may control an image signal obtained through the third camera module 640 not to be provided to the first application assigned with the second authority.
For example, the processor 610 may assign the third authority for controlling the third camera module 640 to the first application, when identifying the security level of the first application as the third security level. However, the processor 610 may control only an on/off operation for the IRED 644 through the first application assigned with the third authority. In this case, the processor 610 may control an image signal of an iris, which is obtained through the third camera module 640, not to be provided to the first application assigned with the third authority.
For example, the processor 610 may assign the fourth authority for controlling any operation of the third camera module 640 to the first application, when identifying the security level of the first application as the fourth security level.

This iris recognition technology is to authenticate the user by using a donut-shape iris pattern between a central black pupil and a sclera (the white of the eye) in the eye of a person. The person's iris has 266 measurable features, and a user may be identified based on the measurable features of the iris. The person's iris is shaped over about 18 months after birth and is protected by an eyelash, an eyelid, and the pupil, and thus the shape of the iris is not easily changed throughout lifetime of the person thereafter, thereby having a higher consistency than other biometric features such as a fingerprint, a signature, voice, face, etc.
