TECHNICAL FIELD

This disclosure relates to user identity authentication, and more particularly to user biometric authentication based on virtual reality.

BACKGROUND

Virtual reality (VR) is a computer technology that uses VR devices, such as headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds, and other sensations that simulate a user's physical presence in a three dimensional (3D) virtual environment and allow the VR user to interact with the virtual environment. Many applications, such as those for gaming, content consumption, and productivity, have been developed to provide user an immersive experience using VR technology. Many VR applications allow in-application purchases, user customization, or parental control. These operations should require user identity authentication for security purposes.

DETAILED DESCRIPTION

The following detailed description describes technologies related to using biometric authentication to verify user identity based on virtual reality (VR), and is presented to enable any person skilled in the art to make and use the disclosed subject matter in the context of one or more particular implementations. Various modifications, alterations, and permutations of the disclosed implementations can be made and will be readily apparent to those or ordinary skill in the art, and the general principles defined may be applied to other implementations and applications, without departing from scope of the disclosure. In some instances, details unnecessary to obtain an understanding of the described subject matter may be omitted so as to not obscure one or more described implementations with unnecessary detail and inasmuch as such details are within the skill of one of ordinary skill in the art. The present disclosure is not intended to be limited to the described or illustrated implementations, but to be accorded the widest scope consistent with the described principles and features.

Virtual reality (VR) is a computer technology that uses VR devices, such as headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds, and other sensations that simulate a user's physical presence in a three dimensional (3D) virtual environment and allow the VR user to interact with the virtual environment. Many applications, such as those for gaming, content consumption, and productivity, have been developed to provide user an immersive experience using VR technology. Many VR applications allow in-application purchases, user customization, or parental control. These operations should require user identity authentication for security purposes. In some cases, the authentication process can be insecure or the VR user may need to use complicated gestures or exit from the virtual environment to perform an identity authentication.

The present disclosure describes technologies for faster and more convenient user identity authentication based on biometric recognition using a VR device, on a target service executed by a user in a VR scenario, and requiring security authentication. When a user uses a VR device to perform a service, the VR device may identify user interaction operations with virtual elements rendered in the VR scenario using one or more sensors. When it is identified that the user interaction operations match one or more pre-stored operations, the VR device may invoke biometric recognition to collect a biometric characteristic of the user and to initiate biometric authentication for the service provided by a service server. If the biometric authentication is successful, the user may perform a service interaction to complete the service. As such, the user may use biometric recognition to quickly perform user identity authentication in the VR environment, to simplify the user identity authentication procedure and ensure account security. For example, using a payment service in a VR environment, biometric authentication through the VR device can permit faster user identity authentication, when compared to entering a password through complicated user interactions with a virtual keyboard.

FIG. 1is a flowchart illustrating an example method100for biometric user identity authentication based on VR, according to an implementation of the present disclosure. For clarity of presentation, the description that follows generally describes method100in the context of the other figures in this description. However, it will be understood that method100may be performed, for example, by any suitable system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some cases, various steps of method100can be run in parallel, in combination, in loops, or in any order. Example method100can be performed by VR software or an application.

At110, using one or more sensors, a VR device user's interactive operations with virtual elements of a VR scenario to perform a service are identified. In some implementations, the sensors can include an infrared sensor, an image sensor, a laser sensor, a radar sensor, or any other sensors that can detect user characteristics, gestures, or interactions in the VR environment. The service can be any service, application, or task performed by the user in the VR environment that requires user identity authentication. For example, the service can be a payment service, such as payment made in VR shopping, VR games, VR-based video-on-demand, or donation to a VR livecast. The virtual element can be a virtual button or pattern generated in a VR scenario to be used by the user to interact with the VR application, such as triggering a biometric authentication. Using again the payment service for example, the virtual element can be a virtual payment button. The user can select the payment button by using a particular gesture or movement (for example, with the head, hand, or body) to initiate the payment service. In some implementations, a gesture can include a 3D gesture performed with a hand.

The VR scenario or VR environment can be created by VR modeling using a modeling tool, such as UNITY, 3DSMAX, or PHOTOSHOP. In some cases, the VR modeling and VR scenario texture mapping can be based on real-life scenarios. For example, texture maps of materials and real-life scenario models can first be collected by photographing real life objects or scenarios. Modeling tools such as PHOTOSHOP or 3DMAX can then be used for texture processing and real-life 3D model creation. The 3D model can then be imported to a UNITY3D (U3D) PLATFORMER and multi-dimensionally rendered through sound effects, graphical interfaces, plug-ins, and lighting. Interaction code can then be executed to convert the 3D model to a VR scenario model.

In some cases, a two-dimensional (2D) or 3D service interface can be created in the VR scenario for performing the service using the 3D modeling tool. For example, the service interface for a payment service can be a virtual checkout counter. The user can interact with the virtual checkout counter using specific interaction operations (for example, a predetermined head posture or a gesture) to make a payment in the VR scenario. From110, method100proceeds to120.

At120, whether the one or more interactive operations match one or more predetermined operations for triggering biometric authentication is determined. After the VR scenario modeling and service interface modeling, the VR device can present the VR scenario and the service interface to the user. In some cases, the VR scenario model and a virtual element for triggering the service interface can be presented to the user. When a user needs to perform the service while engaged in the immersive experience provided by the VR scenario, the user can interact with the virtual element to trigger the service interface.

The user can interact with the virtual element through any movements or gestures. For example, the user can move the head to control the movement of a visual focus, which can be used as an operational focus (for example, a cursor) in the VR scenario. For example, the VR device can use a sensor to track the movement of the head, and use the sensed movement to change the operational focus location in the VR scenario. When the user moves their head to move the operational focus to a virtual element and stay focused on the virtual element for a predetermined amount of time (for example, three seconds), the VR device can determine that the virtual element is selected and trigger the service interface in the VR scenario.

As another example, the user can position the operational focus on the virtual element by moving the hand, and then use a predetermined 3D gesture to select the virtual element. The VR device can use a sensor to track the user's hand movement, calculate depth information of the user's hand with respect to the VR scenario based on the user's hand displacement sensed by the sensor, and then replicate a 3D gesture made by the user in the VR scenario. If the 3D gesture is the same as one of the pre-stored gestures, the VR device can select the virtual element and trigger the service interface in the VR scenario. After120, method100proceeds to130.

At130, biometric authentication for user identity authentication is invoked. In some cases, the VR device can include a biometric recognition function to facilitate user identity authentication. The biometric recognition function can be performed by a biometric sensor that can identify one or more biometric characteristics of the user, such as a fingerprint, iris, or sclera. The biometric sensor can be built-in to the VR device, separate from, but communicably coupled to, the VR device, or integrated on a mobile device, such as a smartphone.

In some cases, the VR device can be a slide-in type VR headset, which can function by inserting or sliding in a smartphone to the headset, and converting the images displayed on the smartphone to VR scenarios. In such cases, the VR device can rely on built-in biometric sensors such as a fingerprint sensor, camera, or microphone to perform fingerprint, iris, or voice recognition.

Using fingerprint authentication for example, the user can first register a fingerprint using a fingerprint sensor, and associate a user service account on a server with the fingerprint information. For example, when the service is a VR payment service, the service account of the user can be a payment account. The user's payment account can be associated with the user's fingerprint information after fingerprint registration. After fingerprint registration, the user can use fingerprint authentication to perform user identity authentication for the service instead of entering a password (for example, an alphanumeric string of characters).

In some cases, the user can log-in to the user account to use the VR device and perform fingerprint authentication prompted in a service interface to access the service in a VR scenario. The VR device can send the fingerprint information and VR device user account log-in information as a registration message to a service server. The service server can use the received information to associate the user's fingerprint information to a service account and save the fingerprint information to a service account mapped to a biometric characteristics database. In some cases, the user account can be the same as the service account.

In some cases, the VR device can perform additional security authentication before sending the registration message to the service server for enhanced security. For example, the VR device can prompt the user to input a password or other security information to verify the user's identity before sending the user's fingerprint registration message to the service server. This process can prevent unauthorized users from fraudulently registering fingerprint information to map to the authorized user's user account. After fingerprint registration, the VR device can initiate biometric authentication based on the user's fingerprint when the user selects a virtual element to trigger the service. For fingerprint authentication, the fingerprint can be collected by a fingerprint sensor.

In some cases, the VR device can perform a bioassay process before collecting biometric information to ensure that the VR device is currently being used by a real person. This process can prevent unauthorized users from using fingerprint or iris images of the authorized user for biometrical authentication and illegally accessing the authorized user's service account. Example bioassay processes can include eye-blinking or heartbeat recognition.

After a real user is detected using the bioassay process, the VR device can prompt the user to perform biometric authentication for accessing the service account. Using a VR payment service for an example, the VR device can present a text prompt in the VR scenario such as “Please scan your fingerprint for payment authentication.” In some cases, it can be difficult for the user to perform fingerprint scanning while in the virtual environment and wearing the VR device. The VR device can prompt one or more virtual elements to indicate a mounting position of the fingerprint sensor on the VR device. The one or more virtual elements can guide the user to scan the fingerprint sensor for fingerprint recognition (for example, on the right side of a VR headset).

In some cases, the VR device can output a static mark or arrow in the user view of the VR scenario, to indicate a relative position of the fingerprint sensor on the VR device. For example, if the fingerprint sensor is mounted on the upper right, front corner of a VR headset, a virtual flickering arrow can be shown in the VR scenario to point to the relative position of the fingerprint sensor. As such, the user can be guided to move the finger towards the upper right corner of her view, to scan the finger for fingerprint recognition.

In some cases, the VR device can output a dynamic mark or arrow in the user view of the VR scenario to guide the user to move the finger to the fingerprint sensor. For example, the dynamic mark can start by pointing to a general direction of the fingerprint sensor location. Other motion sensors can be used to sense the movement of the user's finger or hand by the VR device to dynamically adjust the pointing direction of the mark until the user successfully scans the finger on the fingerprint sensor. Or, the VR device can show a dynamic trajectory of the user's hand or finger movement and the relative location of the fingerprint sensor on the VR scenario, so the user can be aware of the relative position between the finger and the fingerprint sensor.

As such, the user who wears the VR device to experience the virtual environment may not need to remove the VR device to perform biometric authentication. This can help facilitate the user identity authentication process and reduce interruption of the user's immersive VR experience.

In some cases, after biometric information is collected by the VR device, the VR device can generate a biometric recognition request to the service server. The biometric recognition request can include the user's user or service account information and biometric information. The service server can provide a biometric recognition interface to the VR device for receiving the request and submitting the request to the server. In some cases, the services server can cooperate with a biometric recognition server and the biometric recognition interface can be provided by the biometric recognition server.

After receiving the biometric recognition request, the service server can parse the request, acquire the biometric information and the user account information, and compare the biometric information with biometric sample data stored in the biometric characteristic database. In some cases, if a match between the biometric information and a biometric sample data is found, the service server can further verify whether the received user account information matches the account associated with the matching biometric sample data. After comparing the biometric information and user account information with the corresponding information stored in the biometric characteristic database, the service server can return an authentication result to the VR device. In some implementations, the authentication result can be returned as a Boolean-type return value (that is, true or false). If one or both the biometric information and user account information match the corresponding information stored in the biometric characteristic database, a “true” value can be returned to indicate that the biometric authentication succeed. Otherwise, a “false” value can be returned to indicate that the biometric authentication failed.

In some cases, the VR device can perform biometric authentication locally. The user's biometric information can be saved in the VR device during biometric information registration (for example, registering fingerprint information to the user account on the VR device). After the user triggers the service in the VR scenario, the VR device can collect the biometric information of the user, and compare the biometric information with the biometric information saved during biometric information registration. If the biometric information matches the saved information, the biometric authentication for the service succeeds. Otherwise, the biometric authentication fails. After130, method100proceeds to140.

At140, if the biometric authentication is successful, a service interface is presented to the user for performing the service. If the biometric authentication is successful (for example, a returned value is “true”), the VR device can present the service interface corresponding to the service to gather data related to the service, establish a service request, submit the service request to the service server through a service access interface, and perform further interactions with the service server, if needed, to perform the service.

Using a VR payment service as an example, the VR device can present a payment interface to gather payment related data, such as user name, order information, and price, generate a payment processing request, and send the payment processing request to the service server. The service server can process the request and complete the payment.

The following example uses VR shopping to illustrate how biometric authentication can provide a safer, faster, and simpler service experience to the user. It is assumed that the biometric information used is the fingerprint. The service for the VR shopping can be a payment service such as ALIPAY. The virtual element can be a virtual button presented in the VR shopping scenario. The server for the payment service can be a payment server such as the ALIPAY platform based on a server cluster.

The user logs into the VR device using the user's user account or payment account and completes fingerprint registration on the VR device to associate their fingerprint to the payment account. The user's account information and corresponding fingerprint information can be stored in a biometric characteristic database on a payment server. After fingerprint registration, the user can use a finger for biometric authentication in a VR environment.

When wearing the VR device for VR shopping, the items for sale can be presented to the user in the VR scenario and the user can navigate through the item list, select items, or add items to shopping cart using gestures or movements. In some cases, a virtual button (that is, a virtual element) for checkout or payment can be provided when an item is selected or added to the user's shopping cart. The user can use gestures or movements to move an operational focus (for example, a cursor) to the virtual button and use a predetermined gesture(s) or movement(s) to select the virtual button.

The payment service can be initiated after the virtual button is selected and user identity authentication can also be triggered. In some cases, The VR device can perform a bioassay process to determine whether a real user of the VR device is present. If so, the VR device can generate a message prompt in the VR scenario, such as “Please scan your fingerprint for payment authentication”.

Assuming that the fingerprint sensor is mounted on the upper right corner of the VR device, a virtual flickering arrow or a dynamic pointer pointing to the upper right corner can be presented in the VR scenario to guide the user in moving a finger to the fingerprint sensor for fingerprint collection.

After fingerprint collection, the VR device can send a fingerprint authentication request including the collected fingerprint information and the user's user account or payment account information to the payment server. The payment server can compare the fingerprint information with the fingerprint information stored in the biometric characteristic database during fingerprint registration. If the received fingerprint information matches the fingerprint associated with the user account stored in the database, and the payment account information is consistent with the stored user account information, the payment server can return a Boolean-type “true” value to the VR device to indicate that the fingerprint authentication is successful.

After having acknowledged that the payment was successful, the VR device can present a payment interface for the user to input payment data, such as user name, order information, and payment amount related to the payment service, generate and send a payment processing request to the payment server. The payment server can process the payment and complete the purchase.

In some cases, an “authentication-free for small amount” payment process can be used to further facilitate payment speed. For example, when the user triggers the payment service by selecting the virtual button for payment, the VR device can check the price of the items and determine whether the payment amount is less than a preset amount (for example, 20 USD). If the payment amount is less than the preset amount, the VR device can directly generate and send the payment processing request to the payment server without biometric authentication. Otherwise, the user is required to perform biometric authentication before the payment service can be used.
