This disclosure relates generally to the field of augmented reality. More specifically, and without limitation, this disclosure relates to systems and methods for manipulating images of a real scene using augmented reality.
Current techniques for authentication and verification of users suffer from multiple drawbacks. For example, in a typical authentication or verification method, a user registers for an account and provides registration information required for authentication. This registration information typically includes a username and password. As many passwords can be easily guessed, circumvented, or cracked with current technologies, users are typically required to enter a complex password consisting of a combination of different letters, numbers, and/or symbols. However, complex passwords still suffer from technical problems and create security vulnerabilities. Additionally, such passwords can be difficult for users to remember, creating greater security risks when users reuse passwords across multiple accounts or store their passwords in easily accessible locations or documents. Moreover, the typical user interfaces for authentication and verification are standardized and thus easy to manipulate, presenting further security risks. For example, common phishing scams include sending a user an email containing a link to a legitimate-looking login page, where the user is tricked into entering sensitive account information. A need therefore exists for systems and methods of providing improved authentication and verification for users in a secure, user-friendly interface.
Augmented reality technology allows virtual imagery to be mixed with a real-world physical environment. In other words, computer-generated information may be superimposed on images of real-world elements of a physical environment to provide interactive and enhanced user environment. Augmented reality techniques are typically performed in real time and in semantic context with environmental elements. Immersive perceptual information is sometimes combined with supplemental information. For example, the augmented reality view may include information related to a physical environment presented to the user, via a display.
Commercial applications for augmented reality technology are primarily for informational purposes. For example, augmented reality technology may be used in sports broadcasts to superimpose live scores over a live video feed of a sporting event. While it is known to use augmented reality tools to enrich user experience, at present, there is no available method to integrate augmented reality technology into user authentication methods.
The disclosed system and methods for presenting augmented reality content to a user address the existing problems set forth above, as well as other deficiencies in the prior art, and are directed to an improved visual display system for authenticating users by manipulating images of a real scene using augmented reality technology.
Embodiments of the present disclosure use visual display systems and methods to manipulate images of a real scene using augmented reality. The visual display systems enable secure registration and authentication of users via augmented reality technology. In this manner, the disclosed embodiments can provide a marked improvement over the processes known in the prior art.
One embodiment of the present disclosure is directed to a visual display system for manipulating images of a real scene using augmented reality. The system includes at least one processor in communication with a first mobile device, and a storage medium storing instructions that, when executed, configure the at least one processor to perform operations. The operations may include receiving a request from the first mobile device to access an account of a user, receiving a first image from an image sensor of the first mobile device, the first image depicting a real scene, receiving a selection of a first virtual object, receiving an augmented reality image comprising the first virtual object overlaid on the first image, comparing the augmented reality image to one or more stored augmented reality images, authenticating the user based on the comparison, and authorizing access to the user account based on the authentication.

At step 402, system 100 receives a request from a user to register for augmented reality authentication. In some embodiments, the request is received by registration module 110 from mobile device 190 over network 170. For example, the user may interact with a user interface on the mobile device 190 to transmit the request for registration. The user may have a registered account with server system 105. In some aspects, the user may register for one or more augmented reality authentications for one or more registered accounts.
At step 404, system 100 receives registration image data depicting a real scene from a mobile device 190. In some embodiments, registration module 110 provides instructions to a user interface on the mobile device 190. For example, the user interface may instruct the user to capture an image using an image sensor 220 of mobile device 190. The image depicts a real scene such as a bedroom or office or interior of an automobile. In the example embodiments, a real scene can include any scene for which significant details remain substantially constant, such that the particular scene remains recognizable in subsequent images. In some embodiments, a registration image corresponds to a scene that is familiar to and frequented by the user. In some aspects, data representing the captured image is provided to location determination system 140, as discussed below with respect to
At step 406, system 100 receives a selection of one or more virtual images (or virtual objects) to overlay on the registration image. In some embodiments, registration module 110 provides instructions to a user interface on the mobile device 190. For example, the user interface may instruct the user to select one or more virtual images from a list of virtual images. In some aspects, the virtual image may depict a virtual object such as a telephone, teddy bear, geometric shapes, random objects, things or any other virtual object. The virtual images may be acquired from database 180, memory 160, and/or mobile device 190. For example, data representing the virtual images may be acquired from an image sensor 220 or data 216 of mobile device 190. The user interface may then display the registration image from step 404, and instruct the user to select a location on the registration image on which to overlay the selected one or more virtual images. For example, the user may select a first location on the registration image to overlay a first virtual image, and select a second location on the registration image to overlay a second virtual image.
At step 408, the system 100 generates an augmented reality registration image. In some aspects, the augmented reality registration image comprises the selected one or more virtual images overlaid on the registration image at the locations selected at step 406. In some embodiments, the image-processing module 130 receives data representing the registration image, the selected one or more virtual images, and the selected one or more locations on the registration image on which to overlay the selected one or more virtual images, and generates the augmented reality registration image. For example, the image-processing module 130 overlays the virtual image on the registration image at the selected location, and generates the augmented reality registration image. In some embodiments, data representing the augmented reality registration image is sent to location determination system 140, as discussed in further detail below with respect to
At step 410, system 100 stores the augmented reality registration image. For example, the augmented reality registration image may be stored in memory 160, database 180, and/or mobile device 190. In some aspects, the augmented reality registration image is stored in an account associated with the user.
In some embodiments, the user may repeat the steps in method 400 to register for multiple augmented reality authentications. For example, the system may generate and store multiple augmented reality registration images for one or more accounts associated with the user. This enables the system to generate augmented reality registration images for the user based on different registration images depicting real scenes. For example, the user may select their bedroom at their place of residence for a first registration image to generate a first augmented reality registration image. The user may further select their office at their place of business for a second registration image to generate a second augmented reality registration image, for added flexibility.
At step 504, system 100 is configured to receive a first image depicting a real scene. For example, the first image may be received at mobile device 190 associated with the user from sensor 220 and stored in memory 210 for processing by program 212 or application 214. In some embodiments, the first image is transmitted from mobile device 190 to server system 105 via network 170 for processing by authentication module 120 or image processing module 130. In some embodiments, the first image is received at or from the same or a different mobile device as discussed at step 402 during the registration for augmented reality authentication. Authentication module 120 may provide instructions to a user interface on the mobile device 190. For example, the user interface may instruct the user to capture an image using an image sensor 220 of mobile device 190. The user may be instructed to capture substantially the same image as that taken in step 404 during registration. In some aspects, the captured image is provided to location determination system 140, as discussed below with respect to
In some embodiments, authentication module 120 may transmit instructions to the user interface of mobile device 190 to aid the user with the authentication process. For example, the instructions may provide the user interface with a visual aid. In some embodiments, the user is prompted to enter a user identifier associated with the user account after step 502. For example, the user may be prompted to enter a username, token, passcode, mobile device identifier, or other identifier. In some embodiments, the request at step 502 includes the user identifier, mobile device identifier, or a determined location of the mobile device. For example, the user identifier, mobile device identifier, or determined location of the mobile device may be stored in memory 210 and/or transmitted automatically from mobile device 190. Authentication module 120, after receiving the identifier, may then retrieve registration image or augmented reality registration image stored in an account associated with the identifier. For example, the retrieved registration image or augmented reality registration image may be displayed on the user interface of mobile device 190.
In some embodiments, authentication module 120 may compare the determined location of the mobile device with location information embedded in the registration image or augmented reality registration image stored in an account associated with the identifier. For example, authentication module 120 may retrieve the registration image or augmented reality registration image for display on mobile device 190 when the determined location is within a threshold distance of a location determined from the location information embedded in the registration image or augmented reality registration image. In another example, authentication module 120 may retrieve the registration image or augmented reality registration image when the determined location is within a geofence area associated with the location information embedded in the registration image or augmented reality registration image.
In some embodiments, the displayed registration image or augmented reality registration image is a translucent version of the original image. For example, if the location of the device matches the geolocation of the original image, the user may use a translucent version of the original image as a guide for capturing substantially the same image of the real scene as depicted in the registration image or the augmented reality registration image. For example, user may be prompted to capture the same image of the real scene using sensor 220 of mobile device 190.
In some embodiments, system 100 is configured to preprocess the received first image before displaying the retrieved registration image or augmented reality registration image on the user interface of mobile device 190. For example, the first image may be preprocessed to identify some features within the image for comparison with similar features identified in the registration image or augmented reality registration image. For example, the first image may be preprocessed to identify significant features or landmarks within the image, such as a desk, a window, or a bed. If a comparison with the retrieved registration image or augmented reality registration image meets a threshold similarity value, i.e., a threshold match, with respect to the identified significant features or landmarks, the retrieved registration image or augmented reality registration image is displayed on the user interface of mobile device 190. In some embodiments, authentication module 120 may retrieve the registration image or augmented reality registration image for display on mobile device 190 when there is a threshold match with respect to the identified significant features or landmarks, as described above, and when a location of the mobile device is within a threshold distance of a location determined from the location information embedded in the registration image or augmented reality registration image. In some embodiments, authentication module 120 or image processing module 130 may be configured to preprocess the first image.
In some embodiments, system 100 is configured to preprocess an image depicting a real scene obtained from sensor 220 in real-time, before capturing the first image. For example, preprocessing of the image may be conducted in real-time on the mobile device 190, to identify significant features or landmarks within the image as described above. In some embodiments, preprocessing of the image must yield a threshold match with respect to the identified significant features or landmarks within a predetermined amount of time. For example, if the predetermined amount of time expires before yielding a match, method 500 may end without authenticating the user. In some embodiments, the registration image or augmented reality registration image is displayed on the mobile device 190 for a predetermined amount of time to assist the user.
At step 506, system 100 is configured to receive a selection of one or more virtual images to overlay onto the first image. In some embodiments, mobile device 190 receives the selections of virtual images and store the selections in memory 210 for processing by program 212 or application 214. In some embodiments, mobile device 190 transmits the selections of virtual images to server system 105 via network 170 for processing by authentication module 120 or image processing 130. The selection of virtual images in step 506 may proceed similarly to the selection of virtual images in step 406. In some embodiments, authentication module 120 provides instructions to a user interface on the mobile device 190. For example, the user interface may instruct the user to select one or more virtual images from a list of virtual images. In some aspects, the virtual image may depict a virtual object such as a telephone, teddy bear, geometric shapes, random objects, things or any other virtual object. The virtual images may be acquired from database 180, memory 160, and/or mobile device 190. For example, the virtual images may be acquired from an image sensor 220 or data 216 of mobile device 190. In some embodiments, the list of virtual images includes a set of new virtual objects that have not been previously selected by the user. The user interface may then display the first image from step 504, and instruct the user to select a location on the first image on which to overlay the selected one or more virtual images. For example, the user may select a first location on the first image to overlay a first virtual object, and select a second location on the first image to overlay a second virtual object.
At step 508, system 100 generates an augmented reality image. In some embodiments, program 212 or application 214 of mobile device 190 generates the augmented reality image and stores the image in memory 210. In some embodiments, mobile device 190 transmits the first image and the selections of virtual images to server system 105 via network 170, as described above, to generate the augmented reality image. For example, authentication module 120 or image processing 130 may generate the augmented reality image. In some embodiments, step 508 may proceed similarly to the generation of augmented reality image in step 408. In some aspects, the augmented reality image comprises the selected one or more virtual images overlaid on the first image at the locations selected at step 506.
In some embodiments, image-processing module 130 receives the first image, the selected one or more virtual images, and the selected one or more locations on the first image on which to overlay the selected one or more virtual images, and generates the augmented reality image. For example, image-processing module 130 overlays the virtual image on the first image at the selected location, and generates the augmented reality image. In some embodiments, the augmented reality image, and/or the first image, is sent to location determination system 140, as discussed in further detail below with respect to
At step 510, server system 105 calculates a comparison metric, as described in further detail below with respect to
At step 512, server system 105 calculates a confidence score, as described in further detail below with respect to
At step 514, server system 105 authenticates the user based on the confidence score calculated at step 512. For example, authentication module 120 may authenticate the user based on a comparison of the confidence score and a number of predetermined thresholds, as discussed in further detail with respect to
In some embodiments, method 500 may proceed directly from step 506 to step 510 to calculate the comparison metric. For example, server system 105 may receive the first image at step 504 and the virtual images at step 506, and calculate the comparison metric. The comparison metric may reflect a percentage match between the first image and the registration image, a percentage match between the virtual images received at step 506 and the virtual images received during registration at step 406, or a percentage match between a combination of the images. Here, the method continues to step 512 to calculate the confidence score based on the comparison metric. For example, the confidence score may be calculated based on the comparison metric and location information associated with the images and mobile device 190, as discussed in further detail below with respect to
At step 516, server system 105 authorizes access based on the authentication. For example, server system 105 may authorize access to an account associated with the user (e.g., a user account of server system 105) based on the authentication. In some embodiments, the example authentication techniques may be configured to enable access to data on mobile device 190.
At step 602, the location of mobile device 190 is determined (e.g., using location sensors 204).
At step 604, an image is received from mobile device 190. For example, the image may be received from image sensor 220. In some embodiments, the image is received from registration module 110, authentication module 120, image-processing module 130, memory 160, or database 180. The image may depict a real scene captured by image sensor 220, a virtual image, or an augmented reality image generated at steps 408 and 508, as disclosed above.
At step 606, location information determined from step 602 is embedded into the image. For example, geolocation data may be embedded in the image as metadata. In some embodiments, method 600 includes only steps 602 and 604. For example, location determination system 140 may embed the location information in an image stored registration module 110, authentication module 120, image-processing module 130, memory 160, database 180, or mobile device 190.
At step 702, an image is received from (or accessed by) mobile device 190. For example, the image may be captured at mobile device 190 by image sensor 220. In some embodiments, the image may depict a real scene, such as the image received at steps 404 and 504. In some embodiments, the image is an augmented reality registration image comprising one or more virtual images overlaid onto an image received from the mobile device 190. For example, the image verification method 700 can verify that the augmented reality registration image includes an image captured at the mobile device 190 by image sensor 220.
The image verification procedure is then performed at step 704. Image-processing module 130 may verify that the image was received from an image sensor 220 of mobile device 190 by performing one or more of steps 706-714. For example, at step 706, image-processing module 130 may detect a file format of the image at step 706. For example, sensor 220 may capture an image and generate image data using a specific file format. In some aspects, the file format may include a “live” image file, comprising a video file and an image file. As another example, at step 708, image-processing module 130 may detect usage of image sensor 220. For example, augmented reality application 214 or processor 202 may transmit a confirmation that image sensor 220 was used when transmitting the image from mobile device 190 for verification. As another example, metadata embedded in the image, such as a time stamp at the time of image creation, may be compared to a time the image sensor 220 was used to capture the image. As another example, at step 710, image-processing module 130 may verify the image by detecting movement of the mobile device 190 (e.g. using location sensor 204) at the time the image was captured by sensor 220. As yet another example, at step 712, image-processing module 130 may determine a location of mobile device 190 and compare the determined location to geolocation metadata embedded in the image at the time of capture, as disclosed above with respect to
At step 716, image-processing module 130 may verify that the image was received from image sensor 220 of mobile device 190 using one or more of steps 706-714. In some embodiments, method 400 requires image verification before storing the augmented reality image in step 410. In some embodiments, method 500 requires image verification before authenticating a user.
After starting in step 802, image-processing module 130 receives a first image in step 804a. For example, first image may be received from memory, such as memory 160, database 180, or mobile device 190. After step 804a, image-processing module 130 can extract machine-learning features from the image using a convolutional neural network in step 806a. Similarly, after starting in step 802, image-processing module 130 receives a second image in step 804b. For example, second image may be received from memory, such as memory 160, database 180, or mobile device 190. After step 804b, image-processing module 130 can extract machine-learning features from the second image using a convolutional neural network in step 806b. In some aspects, system 100 can be configured to extract machine-learning features from the first and second images using different components of system 100. For example, server system 105 can extract the machine-learning features of the second image, and mobile device 190 can extract the machine-learning features of the first image. The extracted features may include unique features relating to the images, such as a landmark or object depicted within the image. In some embodiments, server system 105 can determine the coordinates of the extracted features within the image.
In some embodiments, first and second images may include registration images depicting a real scene, virtual images depicting virtual objects, and/or augmented reality images generated during methods 400 and/or 500. For example, image-processing module 130 may extract machine learning features from the registration image and the augmented reality image (for example, the augmented reality image generated as described in
After steps 806a and 806b, image-processing module 130 may calculate a comparison metric in step 808. In some embodiments, the calculated comparison metric may reflect a percentage match between the first and second images. This calculation can involve inputting the machine-learning features extracted from the first and second image data into a classifier, such as another neural network. In additional embodiments, image-processing module 130 can be configured to calculate a metric based on the extracted machine-learning features (e.g., an inner product of the machine learning features extracted from the first image data and the machine learning features extracted from the second image). A value of the metric can indicate the degree of similarity between the images. In some instances values of the metric can increase with increasing similarity. In some embodiments, the calculated comparison metric may reflect a degree of similarity between the virtual object's position within the augmented reality registration image and the virtual object's position within the augmented reality image (for example, the augmented reality image generated as described in
In some embodiments, image-processing module 130 may calculate first comparison metric associated with a comparison of the augmented reality image to one or more stored augmented reality registration images. The image-processing module 130 may calculate a second comparison metric associated with a comparison of the first image with one or more stored registration images. In some embodiments, the augmented reality image is matched to the augmented reality registration image based on the first and second comparison metrics, as further discussed below with respect to
At step 902, server system 105 calculates a confidence score representing a level of confidence that a first image matches a second image. In some embodiments, the first and second images include the images depicting a real scene received at steps 404 and 504, the virtual images received at steps 406 and 506, and/or the augmented reality images disclosed in steps 408 and 508. In some embodiments, the confidence score is calculated by image-processing module 130, as disclosed in further detail below with respect to
At step 904, server system 105 compares the calculated confidence score to a first predetermined threshold. In some embodiments, steps 904-914 are performed by authentication module 120. For example, authentication module 120 may determine that the confidence score is greater than the first threshold and proceed to authenticate the user at step 906. If the authentication module 120 determines that the confidence score is less than the first threshold, it may compare the confidence score to a second predetermined threshold at step 908. If the confidence score is determined to be less than the second threshold, authentication module 120 proceeds to step 914 and does not authenticate the user. In some embodiments, if the confidence score is determined to be less than the second threshold, authentication module 120 proceeds to step 910 and performs a verification challenge. For example, the verification challenge may include an over-the-phone challenge. In some embodiments, the over-the-phone challenge includes transmitting a token or passcode to the mobile device 190 associated with the user. The user is then prompted through a user interface to enter the transmitted token or passcode. Authentication module 120 then compares the transmitted and received tokens or passcode to determine if there is a match. The authenticated module 120 then proceeds to step 906 to authenticate the user when there is match. In some embodiments, the token or passcode is a one-time token or passcode that expires after a predetermined amount of time.
Method 1000 begins at step 1002 to calculate a confidence score representing a level of confidence that a first image matches a second image. In some embodiments, the first and second images include the images depicting a real scene received at steps 404 and 504, the virtual images received at steps 406 and 506, and/or the augmented reality images disclosed in steps 408 and 508. In some embodiments, image-processing module 130 may calculate the confidence score at step 1018 by comparing one or more factors associated with the first and second images. For example, the one or more factors may include comparison metric 1004, location information 1006, time stamp information 1008, date stamp information 1010, lighting conditions 1012, image metadata 1014, and device information 1016. In some embodiments, the factors are weighted to calculate the confidence score.
In some embodiments, comparison metric 1004 may be obtained from image-processing module 130 as disclosed above with respect to
In disclosed aspects, location information 1006 includes location information obtained from location determination system 140 and embedded in the first and second images, as disclosed in
Graphical user interface 1202 shows an interface with a grid outline to assist the user in capturing real scene 1102. The graphical user interface 1202 may prompt the user to capture an image, such as real scene 1102. The interface 1202 may further prompt the user to modify the captured image, for example, by prompting the user to select one or more virtual images to overlay on the captured real scene 1102 to generate an augmented reality image. For example, the user may be prompted through user interface 1302 to select a virtual image, such as virtual object 1304 depicting a telephone, to overlay on the captured real scene 1102. The user may select a location on the grid of user interface 1304 on which to overlay the selected virtual object 1304. In some embodiments, the user selects the location on the grid to overlay the virtual image before selecting the virtual image from a list of available virtual images. For example, the user selects a location on the grid, prompting the user interface 1304 to provide a dialogue box prompting the user to select a virtual image from a list of available virtual images. Once the user selects the desired virtual image, it is overlayed on the captured real scene 1102 at the selected location on the grid. In some embodiments, the user selects the desired virtual image first, and then selects the location on the grid on which to overlay the virtual image. In some embodiments, the user selects more than one virtual image to overlay on the captured image. In some embodiments, the steps of capturing the real scene, selecting the virtual image, and overlaying the virtual image onto the real scene to generate the augmented reality image are performed entirely by server system 105 or by mobile device 190. In some embodiments, the images are stored temporarily on mobile device 190 for processing, and then transmitted to server system 105 for storage and/or further processing.
