Title: Preventing Unauthorized Participation in Collaborative Augmented Reality and Virtual Reality Meetings

Description:
BACKGROUND 
     Aspects of the disclosure relate to computing hardware and software, particularly distributed computing hardware and software for collaborative virtual experiences. When individuals participate in collaborative virtual experiences (e.g., virtual meetings, video games, and/or other experiences), they may, in some instances, use an avatar to represent themselves (e.g., rather than displaying an accurate photo, video feed, and/or otherwise displaying their physical appearance). In doing so, the individuals may effectively conceal their physical appearance from other participants. This may, in some instances, allow unauthorized participants to engage in collaborative virtual experiences if they are able to access an account or other credentials for an authorized participant. For example, an unauthorized participant may access a collaborative virtual experience using the credentials of an authorized participant. In these instances, the unauthorized access may remain undetected as the unauthorized participant&#39;s physical appearance may be represented by an avatar of the authorized participant (or otherwise concealed). As such virtual collaborative experiences become more prevalent, it is therefore increasingly important to improve methods for detection and prevention of unauthorized participation. 
     SUMMARY 
     Aspects of the disclosure provide effective, efficient, scalable, and convenient technical solutions that address and overcome the technical problems associated with developing and implementing computer hardware and software that can identify anomalous behavior during enhanced reality experiences and thereby provide increased security. In accordance with one or more embodiments of the disclosure, a computing platform comprising at least one processor, a communication interface, and memory storing computer-readable instructions may receive, from a user device, a request to join an enhanced reality collaborative experience involving use of an avatar in one of: a virtual reality environment or an augmented reality environment. The computing platform may verify an authorization channel for the user device. The computing platform may grant the user device access to the enhanced reality collaborative experience. The computing platform may receive, from a biometric data collection device of a user of the user device, biometric information corresponding to the user. The computing platform may perform, using data collected by the user device and the biometric information corresponding to the user received from the biometric data collection device, anomaly detection to detect one or more anomalies in the avatar&#39;s participation in the enhanced reality collaborative experience from anticipated participation behaviors of a valid user of the avatar. In response to detecting the one or more anomalies in the avatar&#39;s participation in the enhanced reality collaborative experience, the computing platform may perform one or more security actions for the enhanced reality collaborative experience. 
     In one or more instances, the biometric data collection device may be connected to the user device, and receiving the biometric information corresponding to the user may include receiving, from the user device, the biometric information corresponding to the user. In one or more instances, receiving the biometric information corresponding to the user may include receiving, directly from the biometric data collection device, the biometric information corresponding to the user. 
     In one or more instances, performing the one or more security actions may include one or more of: removing the user from the enhanced reality collaborative experience, moving the user to a waiting room of the enhanced reality collaborative experience, prompting the user to re-authenticate to the enhanced reality collaborative experience, sending a notification to a host of the enhanced reality collaborative experience indicating the detected one or more anomalies, and/or performing other security actions. In one or more instances, the data collected by the user device may be one or more of: video data, image data, audio data, and/or other data. 
     In one or more instances, detecting the one or more anomalies may include feeding the video data into an anomaly detection model and identifying, using the anomaly detection model, that the video data includes anomalous movement patterns for the user. In one or more instances, the computing platform may receive historical biometric and pattern information for the user. The computing platform may train, using the historical biometric and pattern information for the user, the anomaly detection model to identify differences between baseline biometric and pattern information for the user and received biometric and pattern information for the user, which may include identifying the differences between: 1) the baseline biometric and pattern information for the user, and 2) the data collected by the user device and the biometric information corresponding to the user. 
     In one or more instances, the computing platform may continuously, throughout a duration of the enhanced reality collaborative experience and for all participants of the enhanced reality collaborative experience: 1) receive biometric information and other data corresponding to the participants, and 2) perform anomaly detection for the participants. In one or more instances, the enhanced reality collaborative experience may be one of: a virtual meeting, a virtual training session, a test taking session, or a collaborative academic session. In one or more instances, performing the anomaly detection may include analyzing one or more of: hand movement of the avatar, a dominant hand of the avatar, a running gait of the avatar, a head turn motion of the avatar, speech patterns of the user, or other movements of the user. 
     These features, along with many others, are discussed in greater detail below.

     DETAILED DESCRIPTION 
     In the following description of various illustrative embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments in which aspects of the disclosure may be practiced. In some instances, other embodiments may be utilized, and structural and functional modifications may be made, without departing from the scope of the present disclosure. 
     It is noted that various connections between elements are discussed in the following description. It is noted that these connections are general and, unless specified otherwise, may be direct or indirect, wired or wireless, and that the specification is not intended to be limiting in this respect. 
     As a brief introduction to the concepts described further herein, one or more aspects of the disclosure relate to an improved process for ensuring security in collaborative virtual experiences. In some instances, avatars may be used in these collaborative virtual experiences to represent an individual. Since it might not be known whether or not the actual participant is real, it may be difficult to ensure that someone using an avatar is actually an authorized participant when participating in such collaborative virtual experiences or alternatively accessing the avatar without authorization (e.g., to spoof and/or otherwise impersonate another user). 
     Accordingly, one or more aspects of the disclosure relate to using a separate authorization channel for each participant that is independent of the quality of the 5G network, and using a token to open a channel of participation on an augmented reality (AR) and/or virtual reality (VR) environment on a 5G network once authentication is complete. In addition, anomaly detection may be performed. For example, the AR/VR system may employ an engine to detect anomalies of the user. In some instances, biometric sensors, a computer interface, an XR safety initiative (XRSI) tool and/or other devices may be used to identify an individual based on personal information. Then, risk scoring may be used to take action in real time with respect to an anomalous user (e.g., put them in a waiting room, log them off, send an alert based on a risk factor, and/or perform other actions). 
     These and other features are described in further detail below. 
       FIGS.  1 A- 1 B  depict an illustrative computing environment configured to prevent unauthorized participation in collaborative AR and VR experiences in accordance with one or more example embodiments.

     Referring to  FIG.  1 B , collaborative meeting authorization platform  102  may include one or more processors  111 , memory  112 , and communication interface  113 . A data bus may interconnect processor  111 , memory  112 , and communication interface  113 . Communication interface  113  may be a network interface configured to support communication between collaborative meeting authorization platform  102  and one or more networks (e.g., network  101 , or the like). Memory  112  may include one or more program modules having instructions that when executed by processor  111  cause collaborative meeting authorization platform  102  to perform one or more functions described herein and/or one or more databases that may store and/or otherwise maintain information which may be used by such program modules and/or processor  111 . In some instances, the one or more program modules and/or databases may be stored by and/or maintained in different memory units of collaborative meeting authorization platform  102  and/or by different computing devices that may form and/or otherwise make up collaborative meeting authorization platform  102 . For example, memory  112  may have, host, store, and/or include collaborative meeting authorization module  112   a , collaborative meeting authorization database  112   b , and/or a machine learning engine  112   c.    
     Collaborative meeting authorization module  112   a  may have instructions that direct and/or cause collaborative meeting authorization platform  102  to prevent unauthorized participation in enhanced reality experiences, as discussed in greater detail below. Collaborative meeting authorization database  112   b  may store information used by collaborative meeting authorization module  112   a  and/or collaborative meeting authorization platform  102  in application of advanced techniques to prevent unauthorized participation in enhanced reality experiences, and/or in performing other functions. Machine learning engine  112   c  may be used to train, host, and/or otherwise maintain a machine learning model that may be used by the collaborative meeting authorization module  112   a  and/or collaborative meeting authorization platform  102  to prevent unauthorized participation in enhanced reality experiences. 
       FIGS.  2 A- 2 E  depict an illustrative event sequence for preventing unauthorized participation in collaborative AR and VR experiences in accordance with one or more example embodiments. Referring to  FIG.  2 A , at step  201 , the first user device  103  may establish a connection with the collaborative meeting authorization platform  102 . For example, the first user device  103  may establish a first wired/wireless data connection with the collaborative meeting authorization platform  102  to link the first user device  103  to the collaborative meeting authorization platform  102  (e.g., in preparation for requesting a collaborative enhanced reality experience). In some instances the first user device  103  may identify whether or not a connection is already established with the collaborative meeting authorization platform  102 . If a connection is already established with the collaborative meeting authorization platform  102 , the first user device  103  might not re-establish the connection. If a connection is not yet established with the collaborative meeting authorization platform  102 , the first user device  103  may establish the first wired/wireless data connection as described herein. 
     At step  202 , the first user device  103  may send a collaborative experience request to the collaborative meeting authorization platform  102 . For example, the first user device  103  may send a request to establish a virtual meeting, a virtual training session, a test taking session, a collaborative academic session, or other collaborative session, any of which may involve the use of enhanced reality (e.g., AR, VR, and/or other enhanced reality technology). In some instances, the first user device  103  may send a request to establish a collaborative experience that involves the use of avatars to represent the physical appearance of one or more participants. In some instances, the first user device  103  may send the request for the collaborative enhanced reality experience to the collaborative meeting authorization platform  102  while the first wired/wireless data connection is established. 
     At step  203 , the collaborative meeting authorization platform  102  may receive the collaborative experience request sent at step  202 . For example, the collaborative meeting authorization platform  102  may receive the collaborative experience request via the communication interface  113  and while the first wired/wireless data connection is established. 
     At step  204 , the collaborative meeting authorization platform  102  may verify an authorization channel for the first user device  103 . For example, the collaborative meeting authorization platform  102  may authorize the first user device  103  based on a user identifier, device identifier, authentication token, and/or other authentication mechanism, which may have been received along with the collaborative experience request. In some instances, in verifying the authentication channel, the collaborative meeting authorization platform  102  may verify an authentication channel that is specific to the first user device  103  and that is independent of quality on a 5G network over which the collaborative experience request was sent. If the collaborative meeting authorization platform  102  verifies the authentication channel for the first user device  103 , the collaborative meeting authorization platform  102  may proceed to step  205 . Otherwise, if the collaborative meeting authorization platform  102  does not verify the authentication channel for the first user device  103 , the collaborative meeting authorization platform  102  might not proceed to step  205 , and may instead await a subsequent request to initiate another collaborative experience. 
     At step  205 , the collaborative meeting authorization platform  102  may initiate the collaborative experience requested by the first user device  103 . For example, the collaborative meeting authorization platform  102  may establish a virtual meeting, a virtual training session, a test taking session, a collaborative academic session, or other collaborative session, any of which may involve the use of enhanced reality (e.g., AR, VR, and/or other enhanced reality technology). In some instances, in initiating the collaborative experience, the collaborative meeting authorization platform  102  may configure the collaborative experience for participation by a user of the first user device  103  (e.g., a first user), which may, in some instances, involve the use of an avatar, representative of the first user, displayed within the collaborative experience. In some instances, in initiating the collaborative experience, the collaborative meeting authorization platform  102  may initiate the collaborative experience on a 5G network. 
     Referring to  FIG.  2 B , at step  206 , the second user device  104  may establish a connection with the collaborative meeting authorization platform  102 . For example, the second user device  104  may establish a second wired/wireless data connection with the collaborative meeting authorization platform  102  to link the second user device  104  to the collaborative meeting authorization platform  102  (e.g., in preparation for sending a request to join the collaborative experience). In some instances, the second user device  104  may identify whether or not a connection is already established with the collaborative meeting authorization platform  102 . If a connection is already established with the collaborative meeting authorization platform  102 , the second user device  104  might not re-establish the connection. If a connection is not yet established with the collaborative meeting authorization platform  102 , the second user device  104  may establish the second wired/wireless data connection as described herein. 
     At step  207 , the second user device  104  may send a collaborative experience request to the collaborative meeting authorization platform  102 . For example, the second user device  104  may send a request to join the collaborative experience established at step  205 . In some instances, the second user device  104  may send the collaborative experience request to the collaborative meeting authorization platform  102  while the second wired/wireless data connection is established. 
     At step  208 , the collaborative meeting authorization platform  102  may receive the collaborative experience request sent at step  207 . For example, the collaborative meeting authorization platform  102  may receive the collaborative experience request via the communication interface  113  and while the second wired/wireless data connection is established. 
     At step  209 , the collaborative meeting authorization platform  102  may verify an authorization channel for the second user device  104 . For example, the collaborative meeting authorization platform  102  may authorize the second user device  104  based on a user identifier, device identifier, authentication token, and/or other authentication mechanism, which may have been received along with the request to join the collaborative experience. In some instances, in verifying the authentication channel, the collaborative meeting authorization platform may verify an authentication channel that is specific to the second user device  104  and that is independent of quality on a 5G network over which the collaborative experience request was sent. If the collaborative meeting authorization platform  102  verifies the authentication channel for the second user device  104 , the collaborative meeting authorization platform  102  may proceed to step  210 . Otherwise, if the collaborative meeting authorization platform  102  does not verify the authentication channel for the second user device  104 , the collaborative meeting authorization platform  102  might not proceed to step  210 , and may instead await a subsequent request to join the collaborative experience and/or otherwise monitor participants of the collaborative experience as described further below. 
     At step  210 , the collaborative meeting authorization platform  102  may admit a user of the second user device (a second user) to the collaborative experience. For example, the collaborative meeting authorization platform  102  may admit the second user to a virtual meeting, a virtual training session, a test taking session, a collaborative academic session, or other collaborative session, any of which may involve the use of enhanced reality (e.g., AR, VR, and/or other enhanced reality technology). In some instances, in admitting the second user to the collaborative experience, the collaborative meeting authorization platform  102  may configure the collaborative experience for participation by the second user, which may, in some instances, involve the use of an avatar, representative of the second user, displayed within the collaborative experience. In some instances, in initiating the collaborative experience, the collaborative meeting authorization platform  102  may initiate the collaborative experience on a 5G network. 
     Referring to  FIG.  2 C , at step  211 , first biometric data collection device  105  and/or the second biometric data collection device  106  may establish a connection with the collaborative meeting authorization platform  102 . For example, the first biometric data collection device  105  and/or the second biometric data collection device  106  may establish a third and/or fourth wired/wireless data connection with the collaborative meeting authorization platform  102  to link the first biometric data collection device  105  and/or the second biometric data collection device  106  (e.g., in preparation for sending biometric information). In some instances, rather than directly connecting to the collaborative meeting authorization platform  102 , the first biometric data collection device  105  and/or second biometric data collection device  106  may establish a connection with the first user device  103  and/or second user device  104 , respectively. In these instances, the first biometric data collection device  105  and/or second biometric data collection device  106  may send the biometric information to the first user device  103  and/or second user device  104 , which may then send the biometric information to the collaborative meeting authorization platform  102 . In some instances, the first biometric data collection device  105  and/or the second biometric data collection device  106  may identify whether a connection is already established with the collaborative meeting authorization platform  102 . If a connection is already established with the collaborative meeting authorization platform  102 , the first biometric data collection device  105  and/or the second biometric data collection device  106  might not re-establish the connection. If a connection is not yet established with the collaborative meeting authorization platform  102 , the first biometric data collection device  105  and/or the second biometric data collection device  106  may establish the third and/or fourth wired/wireless data connection as described herein. 
     At step  212 , the first biometric data collection device  105  and/or the second biometric data collection device  106  may send biometric data to the collaborative meeting authorization platform  102  (either directly or via the first user device  103  and/or second user device  104  respectively). For example, the first biometric data collection device  105  may send biometric data corresponding to the first user and the second biometric data collection device  106  may send biometric data corresponding to the second user. In some instances, the first biometric data collection device  105  and/or the second biometric data collection device  106  may send the biometric information to the collaborative meeting authorization platform  102  while the third and/or fourth wired/wireless data connection is established. In some instances, the first biometric data collection device  105  and/or the second biometric data collection device  106  may implement computer interface, XRSI, and/or other biometrics technology in data collection/transmittal. 
     In some instances, in addition or as an alternative to the biometric information send by the first biometric data collection device  105  and/or the second biometric data collection device  106 , the first user device  103  and/or the second user device  104  may send interaction information for the first user and/or the second user, which may, e.g., include video data, audio data, image data, and/or other information, indicating or otherwise corresponding to interactions of the first and/or second user within the collaborative experience. 
     At step  213 , the collaborative meeting authorization platform  102  may receive the biometric information and/or interaction information sent at step  212 . For example, the collaborative meeting authorization platform  102  may receive the biometric information via the communication interface  113  and while the third and/or fourth wired/wireless data connections are established. For example, in receiving the biometric information and/or interaction information, the collaborative meeting authorization platform  102  may receive information indicating: avatar hand movements, avatar dominant hands, running gaits of the avatars, head turning motions of the avatars, speech patterns, eye movements, and/or other information indicating interactions, movements, and/or other data corresponding to the first user, the second user, and/or any other participants in the collaborative experience. 
     At step  214 , the collaborative meeting authorization platform  102  may feed the biometric information and/or the other interaction information into an anomaly detection model. For example, the collaborative meeting authorization platform  102  may have previously trained a machine learning model using historical biometric and/or interaction information for a plurality of individuals (e.g., including the first user and the second user). In some instances, users may opt in to the collaborative meeting authorization service, and may provide initial interaction and/or biometric information through the creation of a user profile. In some instances, the collaborative meeting authorization platform  102  may prompt users for different amounts/types of information in the user profiles based on services requested by the corresponding users. Once this initial information is used to train the machine learning model, the collaborative meeting authorization platform  102  may collect additional information throughout various user interactions going forward, and may use this information to further train and/or otherwise refine the machine learning model/baselines accordingly (as described further below). In training the machine learning model, the collaborative meeting authorization platform  102  may identify baseline values/patterns of avatar hand movements, avatar dominant hands, running gaits of the avatars, head turning motions of the avatars, speech patterns, eye movements, and/or other information indicating interactions, movements, and/or other data corresponding to the first user, the second user, and/or any of the remaining plurality of individuals. Accordingly, the collaborative meeting authorization platform  102  may configure the machine learning model to identify anomalies in behavior or biometrics for participants in various collaborative experiences. 
     For example, the collaborative meeting authorization platform  102  may identify whether any of the above described metrics are outside of a predetermined tolerance window when compared to the particular individual&#39;s baseline. If any of the above described metrics are outside of the predetermined tolerance window, the collaborative meeting authorization platform  102  may identify an anomaly for the corresponding user. If none of the above described metrics are outside of the predetermined tolerance window, the collaborative meeting authorization platform  102  may identify that no anomalous behavior has been detected for the corresponding user. 
     Although the receipt of information and performance of the anomaly detection is described with regard to steps  212 - 214  above, these processes may be continuous and dynamic throughout a duration of the collaborative experience. For example, data/information corresponding to participants may be continuously received and analyzed to detect any anomalies (e.g., not merely once upon admittance to the collaborative experience). Similarly, as additional data/information is received, the collaborative meeting authorization platform  102  may use this additional data/information to dynamically refine/update the machine learning model to improve its performance, accuracy, and capabilities over time. 
     Such detection may be important, for example, because in such collaborative experiences, as described above, individuals might not be observable themselves within the collaborative experience (e.g., as they would be in a conventional video call). For example, each individual may be represented by an avatar, and thus it may be easier for an unauthorized individual to pose as an authorized individual (because only a corresponding avatar may be visible rather than an image of the individual themselves). Accordingly, such analysis may enable the identification of anomalous behavior, regardless of the use of the avatars, and appropriate action may be taken accordingly (as described further below) to prevent unauthorized individuals from covertly accessing private collaborative experiences. 
     At step  215 , the collaborative meeting authorization platform  102  may identify that the first user is valid or otherwise authorized (e.g., an individual represented by an avatar of the first user is in fact the first user). For example, based on the results of the machine learning model, the collaborative meeting authorization platform  102  may identify that one or more types of data, information, and/or other patterns are within an acceptable tolerance window of baseline data, information, and/or patterns for the first user. Accordingly, the collaborative meeting authorization platform  102  might maintain the first user&#39;s access to the collaborative experience (e.g., allow the first user to remain within the collaborative experience). 
     Referring to  FIG.  2 D , at step  216 , the collaborative meeting authorization platform  102  may identify that the second user is not valid or is otherwise unauthorized (e.g., an individual represented by an avatar of the second user is in fact the second user). For example, based on the results of the machine learning model, the collaborative meeting authorization platform  102  may identify that one or more types of data, information, and/or other patterns are outside of an acceptable tolerance window of baseline data, information, and/or patterns for the second user. Accordingly, the collaborative meeting authorization platform  102  might identify that anomalous behavior has been detected for the second user. 
     At step  217 , the collaborative meeting authorization platform  102  may score the detected anomaly. For example, the collaborative meeting authorization platform  102  may score the detected anomaly based on, for example, a standard deviation (or number of standard deviations) of the detected anomaly when compared to the corresponding baseline. For example, the collaborative meeting authorization platform  102  may assign a score based on the corresponding number of standard deviations. For example, the collaborative meeting authorization platform  102  may apply the following model to score the anomaly: 
     
       
         
           
             
               anomaly 
               ⁢ 
                   
               score 
             
             = 
             
               
                 
                   
                     ∑ 
                     
                       
                         ( 
                         
                           
                             x 
                             
                               i

                           ⁢ 
                           μ 
                         
                         ) 
                       
                       2 
                     
                   
                   N 
                 
               
               . 
             
           
         
       
     
     In these instances, N may represent a data points used to establish the corresponding baseline value plus one (e.g., plus an extra data point representative of the newly received data), μ may represent the previously identified baseline value for the corresponding metric (which may e.g., be an average), and x i  may represent a value of the newly received data. 
     In some instances, the collaborative meeting authorization platform  102  may use these individually identified anomaly scores to establish dynamic and comprehensive compliance scores for each participant in the collaborative experience. In some of these instances, the comprehensive score may be compared to a predetermined security threshold as described below, and security actions may be taken accordingly. In these instances, the comparison of the comprehensive scores may be performed in addition to or as an alternative to the comparison of the specific anomaly scores. 
     At step  218 , the collaborative meeting authorization platform  102  may compare the anomaly score, identified at step  218 , to a predetermined security threshold. For example, the collaborative meeting authorization platform  102  may perform the comparison using the model: 
     
       
         
           
             
               
                 
                   
                     ∑ 
                     
                       
                         (

     no anomaly detected. If the collaborative meeting authorization platform  102  identifies that the anomaly score meets or exceeds the security threshold, the collaborative meeting authorization platform  102  may proceed to step  219 . Otherwise, if the collaborative meeting authorization platform  102  identifies that the anomaly score does not exceed the security threshold, it may proceed to step  223 . 
     At step  219 , based on or in response to detecting that the anomaly score met or exceeded the security threshold, the collaborative meeting authorization platform  102  may perform one or more security actions. For example, the collaborative meeting authorization platform  102  may remove the second user from the enhanced reality collaborative experience, move the second user to a waiting room of the enhanced reality collaborative experience, prompt the second user to re-authenticate to the enhanced reality collaborative experience, and/or perform one or more other security actions. 
     Referring to  FIG.  2 E , at step  220 , the collaborative meeting authorization platform  102  may sending a notification to a host (e.g., the first user) of the enhanced reality collaborative experience (or other network/security analyst) indicating the detected one or more anomalies. In some instances, the collaborative meeting authorization platform  102  may also send one or more commands directing the first user device  103  to display the anomaly detection notification. For example, the collaborative meeting authorization platform  102  may send the notification to the first user device  103  via the communication interface  113  and while the first wired/wireless data connection is established. 
     At step  221 , the first user device  103  may receive the anomaly detection notification sent at step  220 . For example, the first user device  103  may receive the anomaly detection notification while the first wired/wireless data connection is established. In some instances, the first user device  103  may also receive one or more commands directing the first user device  103  to display the anomaly detection notification. 
     At step  222 , based on or in response to the one or more commands directing the first user device  103  to display the anomaly detection notification, the first user device  103  may display the anomaly detection notification. For example, the first user device  103  may display a graphical user interface similar to graphical user interface  405 , which is shown in  FIG.  4   , and which may, for example, indicate that an anomaly has been detected for the second user and prompt the host of the collaborative experience (e.g., the first user) to re-admit the second user if an error was made. 
     At step  223 , the collaborative meeting authorization platform  102  may update one or more anomaly detection baselines based on any received data, patterns, or other information, and any results/outputs from the machine learning model. In doing so, the collaborative meeting authorization platform  102  may continue to iteratively update/refine the machine learning model to improve accuracy of its predictions/analysis over time and account for any drift in preferences/habits of any corresponding individuals. 
     Although a first and second user are described, this is for illustrative purposes only, and any number of individuals may be involved in the above described method without departing from the scope of this disclosure. Furthermore, although identification of unauthorized users is described above, the above described systems and methods may be used to identify behavior that violates a code of conduct for a collaborative virtual experience or is otherwise aggressive/passionate and merits removal/suspension from the experience, without departing from the scope of this disclosure. For example, the collaborative meeting authorization platform  102  may identify use of profanity and/or other inappropriate behavior. In these instances, the above described security actions may be performed as a result. 
       FIG.  3    depicts an illustrative method for preventing unauthorized participation in collaborative AR and VR experiences in accordance with one or more example embodiments. Referring to  FIG.  3   , at step  305 , a computing platform having at least one processor, a communication interface, and memory may receive a request to initiate a collaborative experience. At step  310 , the computing platform may verify an authorization channel corresponding to the request. If the computing platform identifies that the authorization channel corresponding to the request is verified, the computing platform may proceed to step  315 . If the computing platform identifies that the authorization channel is not verified, it may return to step  305  to await another collaborative experience request. 
     At step  315 , the computing platform may initiate the requested collaborative experience. At step  320 , the computing platform may receive a request to join the collaborative experience. At step  325 , the computing platform may identify whether an authentication channel corresponding to the join request is verified. If the computing platform identifies that the authentication channel corresponding to the join request is not verified, it may return to step  320  until another join request is received. If the computing platform identifies that the authentication channel is verified, it may proceed to step  330 . 
     At step  330 , the computing platform may grant access to the collaborative experience. At step  335 , the computing platform may receive biometric and/or other information corresponding to participants in the collaborative experience. At step  340 , the computing platform may input the biometric and/or other information into an anomaly detection model to identify whether or not anomalous behavior is detected. If the computing platform does not detect anomalous behavior, it may return to step  335  to receive further information from the participants. If the computing platform does detect an anomaly, it may proceed to step  345 . 
     At step  345 , the computing platform may score the detected anomaly. At step  350 , the computing platform may compare the anomaly score to a security threshold. If the computing platform identifies that the score does not exceed the security threshold, it may proceed to step  365 . If the computing platform identifies that the score does meet or exceed the security threshold, it may proceed to step  355 . 
     At step  355 , the computing platform may execute a security action. At step  360 , the computing platform may send an anomaly detection notification to a host of the collaborative experience. At step  365 , the computing platform may update the machine learning model based on any newly received data, information, and/or patterns of the participants, and/or the results of the machine learning analysis.
