Identity authentication method and apparatus, and user equipment

TECHNICAL FIELD

The present invention relates to the field of information technologies, and in particular, to an identity authentication method and apparatus, and user equipment.

BACKGROUND

As user equipment is getting smarter, an identity authentication manner of the user equipment becomes increasingly diverse. Common identity authentication manners include password authentication, pattern authentication, peripheral authentication, and biometric feature-based identity authentication. Because the biometric feature-based identity authentication does not require memorization and features high portability, application of this type of authentication manner becomes increasingly common. Biometric feature-based identity authentication manners include fingerprint authentication, face authentication, voiceprint authentication, palmprint authentication, iris authentication, and the like.

Currently, in a biometric feature-based identity authentication method, user equipment first acquires current biometric feature data, then calculates a matching degree between the current biometric feature data and preconfigured biometric feature data, and finally determines whether the matching degree reaches a matching threshold, where if the matching degree reaches the matching threshold, it is determined that identity authentication succeeds; or if the matching degree does not reach the matching threshold, it is determined that identity authentication fails.

However, when it is determined whether the matching degree reaches the matching threshold, a surrounding environment of the user equipment imposes impact, for example, illumination intensity, noise intensity, and temperature in a current environment affect the current biometric feature data, and a location of the user equipment imposes impact, for example, a home, an office, or a restaurant in which the user equipment is located; consequently, the acquired current biometric feature data features relatively low accuracy, resulting in relatively low accuracy of identity authentication.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

An embodiment of the present invention provides an identity authentication method, which is executed by user equipment, where the user equipment has a function of biometric feature-based identity authentication, and identity authentication includes at least two different authentication levels, so that accuracy of identity authentication can be improved. As shown in FIG. 1, the method includes the following steps.

101. The user equipment detects a scenario in which the user equipment is located.

The scenario in which the user equipment is located may include a profile mode, a location, or a surrounding environment of the user equipment.

The manner of performing biometric feature-based identity authentication is fingerprint authentication, palmprint authentication, voiceprint authentication, voice authentication, iris authentication, retina authentication, face authentication, deoxyribonucleic acid (DNA) authentication, vein authentication, hand shape authentication, behavior authentication, or heart sound authentication.

In this embodiment of the present invention, user equipment that has various sensors may be used to detect the scenario, or a wearable device that has various sensors may be used to detect the scenario. The various sensors include a motion sensor, a biometric sensor, an environment sensor, and the like, where the motion sensor further includes a pressure sensor, a speed sensor, an acceleration sensor, a gyroscope, or the like; the biometric sensor further includes an electrocardiograph sensor, a vein sensor, a body temperature sensor, or the like; and the environment sensor further includes a temperature sensor, a humidity sensor, a barometric pressure sensor, a rain sensor, an illumination sensor, a wind speed and direction sensor, or the like. In this embodiment of the present invention, the wearable device may be a smart band, a smart ring, smart glasses, or the like.

102. The user equipment determines, from the at least two different authentication levels, an authentication level corresponding to the scenario in which the user equipment is located.

In this embodiment of the present invention, different scenarios are corresponding to different authentication levels, and a higher authentication level represents a higher trust degree of authentication performed by the user equipment in the scenario.

103. The user equipment acquires current biometric feature data entered by a user.

104. The user equipment determines, according to the current biometric feature data, preconfigured biometric feature data, and the authentication level, whether identity authentication succeeds.

Specifically, when the user equipment performs identity authentication, the user equipment acquires a matching degree between the current biometric feature data and the preconfigured biometric feature data, and if the matching degree is greater than or equal to a matching threshold, the user equipment determines that identity authentication succeeds; or if the matching degree is less than a matching threshold, the user equipment determines that identity authentication fails.

In this embodiment of the present invention, it is determined, by using a matching threshold that is corresponding to a trust level corresponding to a current status or a current environment of the user equipment, whether identity authentication succeeds, which can improve accuracy of identity authentication by the user equipment. For example, if an initial matching threshold is 90%, and the user performs identity authentication by using the user equipment held by the user, when identity authentication is performed in a face authentication manner, and an environment in which the user equipment is currently located is relatively dark, the matching degree that is between the current biometric feature data and the preconfigured biometric feature data and is acquired by the user equipment is 82% due to impact of the current environment, and the user equipment determines, in a current existing authentication manner, that identity authentication fails. In this case, the user needs to repeat identity authentication multiple times. However, in the authentication manner provided in this embodiment of the present invention, a current trust level acquired by the user equipment is a level 4, and a corresponding matching threshold is 80%; further, the user equipment determines that identity authentication succeeds.

According to the identity authentication method provided in this embodiment of the present invention, a scenario in which user equipment is located is first detected; an authentication level corresponding to the scenario in which the user equipment is located is determined from at least two different authentication levels; then current biometric feature data entered by a user is acquired; and finally it is determined, according to the current biometric feature data, preconfigured biometric feature data, and the authentication level, whether identity authentication succeeds. In comparison with a prior-art manner of determining, by using a fixed matching threshold, whether identity authentication succeeds, in this embodiment of the present invention, a trust level of identity authentication by the user equipment in a current status or a current environment can be determined by using a current profile mode of the user equipment, or a location area in which the user equipment is currently located, or a current surrounding environment situation of the user equipment, and a corresponding matching threshold is further determined according to the trust level, so that when the surrounding environment is not favorable for user authentication, and the current environment is relatively safe, the matching threshold for authentication by the user equipment can be reduced, avoiding a case in which identity authentication needs to be repeated multiple times due to impact of a surrounding environment, and improving accuracy of identity authentication.

As a specific description of the method shown in FIG. 1, an embodiment of the present invention provides another identity authentication method. As shown in FIG. 2, the method includes the following steps.

201. User equipment detects a scenario in which the user equipment is located.

The scenario in which the user equipment is located may include a profile mode, a location, or a surrounding environment of the user equipment.

In this embodiment of the present invention, the foregoing manner of performing biometric feature-based identity authentication may be fingerprint authentication, palmprint authentication, voiceprint authentication, voice authentication, iris authentication, retina authentication, face authentication, DNA authentication, vein authentication, hand shape authentication, behavior authentication, heart sound authentication, or the like.

202. The user equipment determines a trust level corresponding to the scenario in which the user equipment is located.

Optionally, when the scenario in which the user equipment is located is the profile mode of the user equipment, the user equipment may preconfigure a correspondence between each profile mode and each trust level. In this case, before step 202, the method may further include: acquiring, by the user equipment, a current profile mode of the user equipment. In this case, step 202 may be specifically: the user equipment determines the corresponding trust level according to the current profile mode of the user equipment and the correspondence between each profile mode and each trust level.

In this embodiment of the present invention, when a user sets the profile mode of the user equipment according to a user requirement, the user equipment can directly acquire the profile mode set by the user; when a user does not set the profile mode of the user equipment, the user equipment may analyze a user requirement according to parameters such as a current date, current time, and a location, and configure and acquire the corresponding profile mode.

Specifically, the acquiring, by the user equipment, a current profile mode of the user equipment may be specifically: the user equipment first acquires profile mode-related parameter information, where the profile mode-related parameter information includes any one or a combination of current location information, current time information, current temperature information, illumination intensity information, or noise intensity information, and then acquires the current profile mode of the user equipment according to the profile mode-related parameter information.

In this embodiment of the present invention, profile modes of the user equipment include a driving mode, a family mode, a meeting mode, an outdoor mode, and the like, and the different profile modes are corresponding to different trust levels. In this embodiment of the present invention, the user may set the correspondence between each profile mode and each trust level according to a user requirement, or the user equipment may preconfigure the correspondence between each profile mode and each trust level, which is not limited in this embodiment of the present invention.

For example, a trust level corresponding to the “driving mode” may be a level 4, a trust level corresponding to the “family mode” may be a level 3, a trust level corresponding to the “meeting mode” may be a level 2, and a trust level corresponding to the “outdoor mode” may be a level 1, where the level 1 is a trust level with a lowest trust degree.

Optionally, when the scenario in which the user equipment is located is the location of the user equipment, the user equipment may preconfigure a correspondence between each location area and each trust level. In this case, before step 202, the method may further include: acquiring, by the user equipment, a location area in which the user equipment is currently located. In this case, step 202 may be specifically: the user equipment determines the corresponding trust level according to the location area in which the user equipment is currently located and the correspondence between each location area and each trust level.

In this embodiment of the present invention, before the user equipment configures the correspondence between each location area and each trust level, the method may further include: dividing, by the user equipment, each location area. Specifically, the user equipment may divide each location area according to geographical location information, or may divide each location area according to a corresponding base station identifier, or may divide each location area according to an identifier of an accessed Wireless Fidelity (WIFI) network, or may divide each location area according to an identifier of a paired Bluetooth device, or may divide each location area according to a charging type.

In this embodiment of the present invention, when the user equipment is located in different location areas, the different location areas are corresponding to different trust levels. In this embodiment of the present invention, the location of the user equipment may be an actual geographical location, or may be an abstract concept, which is not limited in this embodiment of the present invention.

For example, when the actual geographical location is used to represent the location of the user equipment, a highest trust level may be configured for a location in which the user lives, a higher trust level may be configured for a location in which the user works, a lower trust level may be configured for another place (exemplarily, a restaurant, a gym, or the like) frequented by the user, and a lowest trust level may be configured for another location.

For another example, when the abstract concept is used to represent the location of the user equipment, different trust levels may be respectively configured according to identifiers of different base stations accessed by the user equipment; different trust levels may be respectively configured according to identifiers of different WIFI networks accessed by the user equipment; different trust levels may be respectively configured according to identifiers of Bluetooth devices with which the user equipment is being paired; or different trust levels may be configured according to whether the user equipment is being charged.

In this embodiment of the present invention, when the different trust levels are respectively configured according to the identifiers of the different base stations accessed by the user equipment, it is assumed that the different base stations that can be accessed by the user equipment include a base station 1, a base station 2, a base station 3, and a base station 4, where the base station 1 is a base station that covers the user's residential location, and a highest trust level may be configured for the base station 1; the base station 2 is a base station that covers the user's working location, and a higher trust level may be configured for the base station 2; the base station 3 is a base station that covers the user's recreational location, and a lower trust level may be configured for the base station 3; and the base station 4 is a base station that covers another location, and a lowest trust level may be configured for the base station 4.

In this embodiment of the present invention, when the different trust levels are respectively configured according to the identifiers of the different WIFI networks accessed by the user equipment, it is assumed that the different WIFI networks that can be accessed by the user equipment include a WIFI network 1, a WIFI network 2, a WIFI network 3, and a WIFI network 4, where the WIFI network 1 is a WIFI network of the user's residential location, and a highest trust level may be configured for the WIFI network 1; the WIFI network 2 is a WIFI network of the user's working location, and a higher trust level may be configured for the WIFI network 2; the WIFI network 3 is a WIFI network of for the user's recreational place, and a lower trust level may be configured for the WIFI network 3; and the WIFI network 4 is a WIFI network of another location, and a lowest trust level may be configured for the WIFI network 4.

In this embodiment of the present invention, when the different trust levels are respectively configured according to the identifiers of the Bluetooth devices with which the user equipment is being paired, it is assumed that Bluetooth devices with which the user equipment has been paired include a device 1, a device 2, a device 3, and a device 4, where the device 1 is another device held by the user, and a highest trust level may be configured for the device 1; the device 2 is a device held by a family or a good friend of the user, and a higher trust level may be configured for the device 2; the device 3 is a device held by a colleague or a common friend of the user, a lower trust level may be configured for the device 3; and the device 4 is another device, and a lowest trust level may be configured for the device 4.

In this embodiment of the present invention, when the different trust levels are respectively configured according to whether the user equipment is being charged, if the user equipment is being charged by using a fixed power supply, a highest trust level is configured for the user equipment; if the user equipment is being charged by using a mobile power supply, a higher trust level is configured for the user equipment; and if the user equipment is not being charged, a lower trust level is configured for the user equipment.

Optionally, when the scenario in which the user equipment is located is the surrounding environment of the user equipment, the user equipment may preconfigure a correspondence between each environment impact factor and each trust level, where the environment impact factor is used to represent a degree to which identity authentication performed by the user equipment is affected by the surrounding environment, and a larger value of the environment impact factor is corresponding to a higher trust level. In this case, before step 202, the method may further include: acquiring, by the user equipment, a current environment impact factor of the user equipment. In this case, step 202 may be specifically: the user equipment determines the corresponding trust level according to the current environment impact factor of the user equipment and the correspondence between each environment impact factor and each trust level.

In this embodiment of the present invention, the acquiring, by the user equipment, a current environment impact factor of the user equipment may be specifically: the user equipment first acquires environment impact factor-related parameter information, where the environment impact factor-related parameter information includes any one or a combination of current location information, current time information, current temperature information, illumination intensity information, or noise intensity information; and then acquires the current environment impact factor of the user equipment according to the environment impact factor-related parameter information.

In this embodiment of the present invention, when the user equipment is located in different surrounding environments, the different surrounding environments are corresponding to different trust levels. In this embodiment of the present invention, the different surrounding environments may be determined according to parameters such as illumination intensity, environment noise, temperature, and humidity.

For example, if the user equipment is located in a same location during the day and at night, and illumination intensity is different, it is considered that surrounding environments are different, and different trust levels are configured for the surrounding environments.

203. The user equipment determines, according to the trust level and a correspondence between each trust level and each matching threshold, a matching threshold corresponding to the trust level.

In this embodiment of the present invention, an authentication level may be a matching threshold.

Optionally, before step 203, the method may further include: configuring, by the user equipment, the correspondence between each trust level and each matching threshold, where the trust level is used to represent a degree to which the user is trusted in a current scenario, and the matching threshold is used to determine whether identity authentication succeeds; and a higher trust level is corresponding to a lower matching threshold.

In this embodiment of the present invention, different trust levels are respectively corresponding to different matching thresholds. In this embodiment of the present invention, if a trust level is higher, that is, the degree to which the user is trusted in the current scenario is higher, a corresponding matching threshold is lower.

For example, a trust level is a level 4, and a corresponding matching threshold may be 60%; a trust level is a level 3, and a corresponding matching threshold may be 70%; a trust level is a level 2, and a corresponding matching threshold may be 80%; and a trust level is a level 1, and a corresponding matching threshold may be 90%.

In this embodiment of the present invention, the user equipment may preconfigure a corresponding lowest matching threshold for each authentication manner, and a matching threshold corresponding to any trust level cannot be lower than the lowest matching threshold. In this embodiment of the present invention, the corresponding lowest matching threshold is configured for each authentication manner, which can avoid a case in which another user can also be successfully authenticated due to an excessively low matching threshold, that is, can ensure security of identity authentication by the user equipment.

In this embodiment of the present invention, the user equipment may configure the correspondence between each trust level and each matching threshold according to a user requirement, or the user equipment may preconfigure the correspondence between each trust level and each matching threshold.

It should be noted that this embodiment of the present invention is not limited to adjusting a matching threshold of one authentication manner, and adjusting matching thresholds of any quantity of authentication manners is also applicable to this embodiment of the present invention. For example, weighted matching thresholds of two authentication manners supported by the user equipment are adjusted.

204. The user equipment acquires current biometric feature data entered by a user.

205. The user equipment determines, according to a matching degree between the current biometric feature data and preconfigured biometric feature data, and the matching threshold, whether identity authentication succeeds.

Optionally, step 205 may be: if the matching degree is greater than or equal to the matching threshold, the user equipment determines that identity authentication succeeds; or if the matching degree is less than the matching threshold, the user equipment determines that identity authentication fails.

Optionally, step 205 may further be: when the matching degree is greater than or equal to the matching threshold, the user equipment acquires an operation type corresponding to a current biometric feature, and determines whether the operation type is the same as a preconfigured operation type. Further, if the operation type is the same as the preconfigured operation type, the user equipment determines that identity authentication succeeds; or if the operation type is different from the preconfigured operation type, the user equipment determines that identity authentication fails.

Different preconfigured operation types may be configured for different identity authentication manners. Exemplarily, when the user equipment performs voiceprint authentication, the preconfigured operation type may be a preconfigured password, for example, “Today is the eighth day of a week”; when the user equipment performs behavior authentication, the preconfigured operation type may be a preconfigured behavior, for example, the user raises a hand; when the user equipment performs fingerprint authentication, the preconfigured operation type may be preconfigured pressing pressure.

In this embodiment of the present invention, after the matching threshold for performing identity authentication by the user is reduced, the user equipment performs further authentication, that is, determining whether the operation type is the same as the preconfigured operation type, which can avoid a case in which another user can also be authenticated successfully after the matching threshold is reduced, that is, can ensure security of identity authentication by the user equipment.

In this embodiment of the present invention, before the matching threshold is adjusted according to the scenario in which the user equipment is located, a matching threshold for performing identity authentication by the user equipment is an initial matching threshold; and after being adjusted, a matching threshold for performing identity authentication by the user equipment is a current matching threshold. In this embodiment of the present invention, when the matching degree is greater than or equal to the initial matching threshold, the user equipment does not need to perform the foregoing step of acquiring and determining the operation type, and it may be considered that identity authentication succeeds; or when the matching degree is greater than or equal to the current matching threshold and is less than the initial matching threshold, the user equipment may perform the foregoing step of acquiring and determining the operation type, so as to ensure security of identity authentication.

An embodiment of the present invention provides another identity authentication method, which is executed by user equipment, where the user equipment has at least two different authentication manners, so that accuracy of identity authentication can be improved. As shown in FIG. 3, the method includes the following steps.

301. The user equipment detects a scenario in which the user equipment is located.

The scenario in which the user equipment is located may include a profile mode, a location, or a surrounding environment of the user equipment.

In this embodiment of the present invention, the foregoing at least two different authentication manners include any combination of fingerprint authentication, palmprint authentication, voiceprint authentication, voice authentication, iris authentication, retina authentication, face authentication, deoxyribonucleic acid (DNA) authentication, vein authentication, hand shape authentication, behavior authentication, or heart sound authentication.

302. The user equipment determines, from the at least two different authentication manners, a target authentication manner corresponding to the scenario in which the user equipment is located.

The target authentication manner is an optimal authentication manner for the user equipment in the scenario in which the user equipment is located.

In this embodiment of the present invention, the user equipment may determine the target authentication manner according to authentication success rates respectively corresponding to the at least two different authentication manners in the scenario in which the user equipment is located.

303. The user equipment acquires current biometric feature data used for the target authentication manner.

304. The user equipment determines, according to the current biometric feature data, and preconfigured biometric feature data corresponding to the target authentication manner, whether identity authentication succeeds.

According to the identity authentication method provided in this embodiment of the present invention, a scenario in which user equipment is located is first detected; a target authentication manner corresponding to the scenario in which the user equipment is located is determined from at least two different authentication manners; then current biometric feature data used for the target authentication manner is acquired; and finally it is determined, according to the current biometric feature data, and preconfigured biometric feature data corresponding to the target authentication manner, whether identity authentication succeeds. In comparison with a current manner of performing identity authentication only in one authentication manner, in this embodiment of the present invention, an authentication success rate corresponding to each authentication manner in a current scenario can be obtained through calculation by using parameter information related to a current status or a current environment, so that identity authentication can be performed for a user in an authentication manner with a highest authentication success rate in the current scenario, avoiding a case in which identity authentication needs to be repeated multiple times in some authentication manners due to impact of a surrounding environment, and improving accuracy of identity authentication.

As a specific description of the method shown in FIG. 3, an embodiment of the present invention provides another identity authentication method. As shown in FIG. 4, the method includes the following steps.

401. User equipment detects a scenario in which the user equipment is located.

The scenario in which the user equipment is located may include a profile mode, a location, or a surrounding environment of the user equipment.

402. The user equipment acquires authentication success rates respectively corresponding to at least two different authentication manners in the scenario in which the user equipment is located.

Optionally, before step 402, the method may further include: first acquiring, by the user equipment, current location information and current time information; then sending an authentication success rate request message to a server, where the authentication success rate request message carries the current location information, the current time information, and the at least two different authentication manners; and finally receiving an authentication success rate response message sent by the server, where the authentication success rate response message carries the authentication success rates respectively corresponding to the at least two different authentication manners. In this case, step 402 may be specifically: the user equipment acquires the authentication success rates respectively corresponding to the at least two different authentication manners from the authentication success rate response message.

Optionally, after step 402, the method may further include: storing, by the user equipment, a correspondence between the scenario in which the user equipment is located and the authentication success rates respectively corresponding to the at least two different authentication manners.

In this embodiment of the present invention, the user equipment stores the correspondence between the scenario in which the user equipment is located and the authentication success rates respectively corresponding to the at least two different authentication manners, so that the prestored correspondence between the scenario in which the user equipment is located and the authentication success rates respectively corresponding to the at least two different authentication manners can be directly acquired when a user is in the scenario again, and the authentication success rates respectively corresponding to the at least two different authentication manners are acquired according to the correspondence, thereby reducing complexity of acquiring the authentication success rates.

403. The user equipment determines an authentication manner with a highest authentication success rate from the at least two different authentication manners as a target authentication manner according to the authentication success rates respectively corresponding to the at least two different authentication manners.

Optionally, step 403 may be specifically: the user equipment first acquires related parameter information respectively corresponding to the at least two different authentication manners in the scenario in which the user equipment is located, where the related parameter information includes any one or a combination of current location information, current time information, current temperature information, illumination intensity information, or noise intensity information; and then acquires, according to the related parameter information respectively corresponding to the at least two different authentication manners, the authentication success rates respectively corresponding to the at least two different authentication manners.

It should be noted that the target authentication manner may be one authentication manner, or may be multiple authentication manners. This embodiment of the present invention is described by using a case in which the target authentication manner is one authentication manner, but this embodiment of the present invention is not limited to the case in which the target authentication manner is one authentication manner, and a case in which the target authentication manner is any other quantity of authentication manners is applicable to this embodiment of the present invention.

404. The user equipment acquires current biometric feature data used for the target authentication manner.

405. The user equipment determines, according to the current biometric feature data, and preconfigured biometric feature data corresponding to the target authentication manner, whether identity authentication succeeds.

Optionally, step 405 may be specifically: the user equipment first calculates a matching degree between the current biometric feature data and the preconfigured biometric feature data corresponding to the target authentication manner, and then determines whether the matching degree is greater than or equal to a matching threshold corresponding to the target authentication manner, where if the matching degree is greater than or equal to the matching threshold, the user equipment determines that identity authentication succeeds; or if the matching degree is less than the matching threshold, the user equipment determines that identity authentication fails.

In this embodiment of the present invention, the user equipment may further provide respective corresponding authentication manners for different shortcut functions. Specifically, when the user equipment is in a locked state, a user lights up a device screen, and when the user's finger slides down from a central icon location to a camera icon location, the user equipment enters a photographing mode; when the user's finger slides up from the central icon location to an SMS icon location, the user equipment enters an SMS editing interface; when the user's finger slides left from the central icon location to a phone icon location, the user equipment enters a phone call interface; and when the user's finger slides right from the central icon location to a browser icon location, the user equipment enters a search interface. In this case, the user equipment detects an operation intention of the user, and when entering a specific function in a shortcut manner, the user equipment activates an authentication manner corresponding to the specific function to prompt the user to perform identity authentication. For example, it is preset that a shortcut manner of enabling a camera function is bound with face authentication, a shortcut manner of enabling an SMS function is bound with voice authentication, a shortcut manner of enabling a phone function is bound with voiceprint authentication, and a shortcut manner of enabling a browser function is bound with fingerprint authentication.

In this embodiment of the present invention, the respective corresponding authentication manners are provided for the different shortcut functions, and that different shortcut manners are corresponding to different biometric feature authentication manners can be preset, avoiding a tedious case in which the user needs to perform identity authentication again after the user uses the specific function in a shortcut manner, and improving the identity authentication.

In this embodiment of the present invention, the user equipment may provide a same authentication manner for the different shortcut manners, but the different shortcut manners are corresponding to different matching thresholds. For example, it is preset that a shortcut manner is bound with fingerprint authentication, and when the shortcut manner of the camera function is enabled, a matching threshold of fingerprint authentication is 50%; when the shortcut manner of the SMS function is enabled, a matching threshold of fingerprint authentication is 60%; when the shortcut manner of the phone function is enabled, a matching threshold of fingerprint authentication is 70%; and when the shortcut manner of the browser function is enabled, a matching threshold of fingerprint authentication is 80%.

Further, in implementation of the methods shown in FIG. 1 and FIG. 2, an embodiment of the present invention further provides an identity authentication apparatus, where the apparatus may be located in user equipment, the user equipment has a function of biometric feature-based identity authentication, identity authentication includes at least two different authentication levels to improve accuracy of identity authentication, and the apparatus is configured to improve accuracy of identity authentication. As shown in FIG. 5, the apparatus includes a detection unit 51, a determining unit 52, an acquiring unit 53, and a judging unit 54.

The detection unit 51 is configured to detect a scenario in which the user equipment is located.

The determining unit 52 is configured to determine, from the at least two different authentication levels, an authentication level corresponding to the scenario in which the user equipment is located and that is detected by the detection unit 51.

The acquiring unit 53 is configured to acquire current biometric feature data entered by a user.

The judging unit 54 is configured to determine, according to the current biometric feature data acquired by the acquiring unit 53, preconfigured biometric feature data, and the authentication level determined by the determining unit 52, whether identity authentication succeeds.

The scenario in which the user equipment is located and that is detected by the detection unit 51 includes a profile mode, a location, or a surrounding environment of the user equipment.
