Title: Live video anomaly detection

Description:
BACKGROUND 
     The present invention generally relates to computer systems, and more specifically, to live video anomaly detection. 
     Recording and video capturing devices are widely available and are part of our everyday lives. There are many applications that support live streaming and video chat sessions where various type of information can be exchanged. These applications are useful in both personal settings when communicating with family members who live a distance away using tablets and/or mobile phones and are also useful in business enterprise settings when conducting meetings with international partners in conference rooms equipped with webcams or other image/video capturing devices. Live streaming video capability has enhanced the daily lives of its users by providing convenience and efficient exchange of information. 
     SUMMARY 
     Embodiments of the present invention are directed to computer-implemented methods, computer program products and systems for live video anomaly detection. The embodiments include detecting live stream data, determining an activity from the live stream data, and receiving contextual data associated with the live stream data. The embodiments also include prompting a user to redirect the live stream data from a first channel based on the activity and the contextual data, and redirecting, responsive to the prompt, the live stream data to a different channel and simultaneously maintaining the live stream data on the first channel.

Accordingly, in the interest of brevity, many conventional implementation details are only mentioned briefly herein or are omitted entirely without providing the well-known system and/or process details. 
     It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. 
     Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. 
     Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. 
     Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes. 
     Referring now to  FIG. 1 , illustrative cloud computing environment  50  is depicted. As shown, cloud computing environment  50  comprises one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment  50  to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices  54 A-N shown in  FIG. 1  are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser). 
     Referring now to  FIG. 2 , a set of functional abstraction layers provided by cloud computing environment  50  ( FIG. 1 ) is shown.

     In today&#39;s environment, user devices are equipped with video capturing abilities and these devices as well as other monitoring/video capturing systems are present in our daily lives. Various applications can support live streaming. However, applications do not support live streaming and redirecting the current live stream to an external system unrelated to the live streaming application. For example, when a user is recording and live streaming an emergency situation where appropriate authorities should get involved, users are faced with the dilemma of either continuing the live feed or stopping the live feed to dispatch the proper respondents to the emergency situation being captured. Currently, only after the footage is recorded can the proper individuals such as the police, journalists, lobbyists, etc. 
     In one or more embodiments of the invention, the techniques described herein provide users the ability to live stream video and redirect the live stream to an unrelated external system while continuing the live stream. In addition, the techniques also include the ability to dynamically recognize anomalies within the live stream relative to a specific user filming the live stream. Based on the user&#39;s sensitivities and the contextual information, the system can provide a prompt to redirect the live feed to an appropriate channel. The invention leverages pattern and facial recognition, contextual recognition of video, machine-learning, etc. to select a redirection channel. 
     Turning now to an overview of technologies that are more specifically relevant to aspects of the invention, social media platforms and applications offer live streaming capabilities. In addition, a user&#39;s social media profile can offer information related to the user&#39;s like/dislikes and preferences which can provide further information on the user&#39;s sensitivities to various events. For example, a user may post videos related to extreme sports where the user has participated in. In addition, the user&#39;s comments can be analyzed to determine whether user likes extreme sports or has no interest. Posts that a user has shared can be also be used to show a user&#39;s preference. The techniques described herein leverage social media and other publicly accessible information. 
     Turning now to an overview of the aspects of the invention, one or more embodiments of the invention address the above-described shortcomings of the prior art by providing the functionality to determine an anomaly occurring in a live stream and providing a prompt to redirect the live feed to the appropriate parties. In one or more embodiments of the invention facial recognition can be used to identify the individuals being filmed and this information can be leveraged to provide notifications to their important contacts. 
     In one or more embodiments, the invention utilizes situational training relative to the user or surrounding situations to detect anomalies of different situations. Data is collected from the emergency situations that have been captured either by the user or by other users and the responses taken. 
     In the event a similar event is captured during the live video stream after training, data inputs and severity are used to understand the emergency situation. Based on a one or more of the data inputs, event tolerance, detected event, and the available response channels, the appropriate channel is selected. The live stream of the emergency situation is transmitted on the appropriate channel, including the segment displaying the scenario. The user can be prompted to invoke the emergency channel or entirely bypassing the invocation based on the situation. These measurements are user specific and anomaly indicators for a specific event are not necessarily the same across different users depending on their exposure to such an event. 
     The above-described aspects of the invention address the shortcomings of the prior art by providing additional functionality to the user during the recording of a live stream. The live stream can be redirected to an appropriate channel and can be simultaneously maintained on the original recording device. 
     Turning now to a more detailed description of aspects of the present invention,  FIG. 4  illustrates a block diagram of a system  400  for a live video anomaly detection system according to one or more embodiments. In the illustrative embodiment,  FIG. 4  depicts a user device  402  where the user device  402  includes an image capturing device. The user device  402  includes a plurality of modules and sensors to collect data. It should be understood that other devices, processors and modules can be included in the present invention. The image/video capturing device is configured to record live stream  404  events and activities over a first channel  410 . The user device  402  configured to communicate with server  406  which can also store data. The user device  402  is also configured to detect data from receive contextual data from other sensors/devices  408 . Sensors/devices can include but are not limited to smartwatches, smart appliances, baby monitors, microphones, thermometers, gyroscopes and accelerometers, etc. 
     In addition, the server  406  is configured to process an analyze data from other users  430  such as other user profile data and factoring other users&#39; sensitivities towards a detect activity. 
     In one or more embodiments, the user device  402  is configured to redirect data to one of a plurality of channels  412  to other entities/contacts  430 . One channel can be provided to emergency responders, another channel can be provided for the police, and a different channel can be for designated emergency contacts configurable by the user. In one or more embodiments of the invention, the live stream anomaly detection system  400  can be determined from a frequently contacted list of the user recording the live stream. Embodiments of the invention include the system analyzing the inputs and other contextual data within proximity of the user device  402  to automatically select the appropriate redirection channel  412  to transfer the live stream and/or or recorded video to one or more the contacts  440 . 
     In one or more embodiments of the invention, the anomaly indicator table is calculated case by case for each user/activity depending on the type of sensor collecting the information. Measurements and calculations are user specific and anomaly indicators for a specific activity are not necessarily the same across different users depending on the user&#39;s exposure to such an event. 
     For example, in the case of gunshots recorded in the table above the microphone can calculate/measure decibel levels, repeated patterns, distance, etc. 
     In one or more embodiments of the invention, a user&#39;s sensitivities and tolerance levels can be updated as their responses are recorded and change over time. Upon the detection of live stream feed, if the user&#39;s calculated tolerance has been exceeded, the live video anomaly detection system  400  can provide a prompt to the user based to redirect the live feed to the appropriate authorities. 
     Now referring to  FIG. 5 , a user specific profile  500  used in live video anomaly detection is shown. The data stored in the user specific profile  500  includes data for previous occurrences and reactions for a specific user that have been captured. Similar circumstances can lead to different outcomes for a range of users based on each respective user&#39;s determined sensitivities. The data can be detected by various techniques or input by the user. 
     The user specific profile  500  includes activities/events of previous occurrences. In addition, facial recognition relevance data, audio sentiment data, situational analysis data, event tolerance data, response information, and severity information is stored. 
     “Previous occurrence” identifies scenarios that have been previously live streamed by a user. A few non-limiting examples from the profile  500  includes capturing footage of “a person falling off the roof,” “a child falls and breaks arm,” and “wrestling event, person falls.” 
     “Emotion” data indicates the emotion of the person captured in the live stream. In this example, “1” indicates an intense emotion where “0” indicates no emotion at all. 
     “Facial recognition relevance” to the user is detected. For example, facial expressions can be compared to that of the user to determine whether the facial expression of the live recording provides a similar facial expression as the user. For example, a happy face of a user can be compared to a happy face of a person in the live stream. The higher the correlation, the higher the value is attributed to this factor. 
     “Audio sentiment” provides data on the audio of the live stream. For example, the loud cheers for a wrestler can be discerned from loud aggressive language used in a street fight. 
     “Situational analysis” factors other contextual information related to the occurrence of an activity. For example, the system can determine a location of a person that has fallen. For example, a person falling off of a roof is different than a child falling in a playground which is also different than a wrestling falling in a wrestling match. The higher the value for the situational analysis, the stronger the contextual information supports the occurrence of a particular event. 
     “Event tolerance” indicates a threshold where the user recording the live stream is to be prompted for a redirection of the channel. In this non-limiting example, a “0” indicates no tolerance where the user should be prompted immediately. “1” indicates a high tolerance to the content of the live stream feed. 
     In one or more embodiments, the social media profile data of the user can be analyzed to determine how a particular event appeals to a person&#39;s sensitivities. For example, the sight of blood may be less of a shock to an experienced doctor compared to a young adult who is disturbed by the sight of blood. 
     “Responses” includes calling  911  or notifying a particular in-case of emergency contact (ICE). In addition, the “response” can include taking no action. 
     “Severity” indicates a level of urgency or potential harm. The severity can be determined based on a combination of the previously mentioned factors. In addition, the severity can be confirmed by the user after the occurrence. In this example, the severity is measured between indicators including highest, high, medium, low, none. In the event  911  is called, the system can automatically indicate the previous occurrence with the “highest” severity. 
     In one or more embodiments of the invention, anomaly indicator table  600  can be stored in the user device  402 . In another embodiment, the anomaly indicator table  600  can be stored in the server such as server  406  of  FIG. 4 . 
     Now referring to  FIG. 6 , an anomaly indicator table  600  used in live video anomaly detection in accordance with one or more embodiments. 
     The anomaly indicator table  600  stores data used to determine that an anomaly is being captured by the user device  402 . In one or more embodiments of the invention, the anomaly indicator table  600  can be stored in the user device  402 . In another embodiment, the anomaly indicator table  600  can be stored in the server such as server  406  of  FIG. 4  and accessed by the user device  402 . It should be understood that other data can be used in the determination. 
     Continuing with reference to  FIG. 6 , the anomaly indicator table  600  includes event/activity data, location information, date/time information, context indicator, detection method, anomaly indicators, and contextual recognition information. 
     The event/activity information provides data of the live stream being captured. Event/activity information can be determined by the user device by a number of techniques. As a live video stream is captured, the location information can provide an indication. For example, Frank&#39;s Gun Park can indicate the gunshots are detected. 
     The anomaly indicator table  600  includes location information of the event/activity. The location can be obtained by location systems such as GPS. 
     The date and time information can be used provide further information about whether a certain activity is occurring at normal times are odd times. Continuing with Frank&#39;s Gun Park example, the days/hours of operation of the establishment can be obtained from an Internet search and compared to the time/date the live stream is filmed. The table  600  indicates the date is Nov. 2, 2017 at 2:52 which is during the normal hours of operation which weighs towards a normal scenario. 
     The context indicator provides additional data that can be collected by other devices, sensors, etc. The detectors can include cameras, microphones, smartwatches, smart devices such as smart appliances, TVs. A network of devices can be used to determine the circumstances surrounding the activity/event of the live feed being recorded. In one or more embodiments of the invention, data can be collected by a variety of sensors from nearby IoT sensors. 
     The analysis of the live stream at Frank&#39;s Gun Park uses facial recognition where happy facial expressions were captured in the live stream. This can indicate that there is no reason for alarm and no anomaly is detected. 
     The detection method indicates the device that detected the context indicator data. For example, the gunshots are detected by a microphone of a user device such as a mobile phone or smartwatch. In addition, data from the microphone can be further analyzed to calculate the decibel level, frequency of this type of event (how many times similar readings have occurred), type of gunshot via tonal/decibel analysis of readings from various weapons, rate of fire, proximity, etc. in order to determine the potential danger, harm, anomalous occurrence. 
     In addition, the facial expressions are captured by the video capturing device of the user device using facial recognition technology. It should be understood that other types of facial expressions can be detected such as apprehension, sadness, anxiety, etc. 
     The contextual recognition can provide information on the type of event/activity. The contextual recognition of a video feed and compared against calculated tolerance level for each given event type and determine if the severity/intensity of the event being captured in the live video feed exceeds the tolerance level and should trigger a response in the system. If the response/prompt is ignored, continued recognition of the event that is exceeding tolerance level will trigger a second response/prompt for user interaction. The prompt may also include an option to begin recording the feed and subsequently forwarding the feed to a necessary/desired party. 
     In a non-limiting example, screaming resulting from an argument in a home setting can be distinguished from yelling and cheering at a concert or show. As shown in  FIG. 6  the location can be determined using sensors. In addition, the live stream video can be analyzed to determine the facial expressions of those in proximity. Facial expressions showing anger and/or panic and audio indicating shouting can be an indicator of violence. Also, the audio can be analyzed to determine the types of words that are being used. Sensors such as smartwatches including heart rate monitors can be used to detect the heart rate of the user. A normal heart rate of the user filming and witnessing the event, based on a history of the user&#39;s heart rate, can indicate that the user is filming an abnormal situation. If the event live stream is filming a concert, a schedule of the concert can be searched to confirm that a concert matching the location, venue, and time in fact exists. 
     In one or more embodiments of the invention, a car crash occurring in a movie can be distinguished from a car crash in a movie. For example, sensors can detect the location, context indicators can detect whether the audio profile matches a movie&#39;s audio profile. In addition, sensors such as smartwatches can detect the heart rate of the user to be factored in the determination. 
     Now referring to  FIG. 7 , a flowchart  700  for live video anomaly detection is shown. Block  702  includes detecting live stream data. In one or more embodiments of the invention, the live stream data/feed is recorded using a user device such as a mobile phone, tablet, computer, and the like having video capturing capability. 
     Block  704  includes determining an activity from the live stream data. The system analyzes the live stream data to determine an activity being conducted in the live stream. 
     Next, as shown at block  706 , the method  700  includes receiving contextual data associated with the live stream data. In one or more embodiments of the invention, the contextual data can include data provided from one or more sensors of the device or one or more external devices such as smart devices and smart appliances. For example, location data can be used to determine a venue such as movie theatre or park. The location data can be used to determine whether the user is hearing gunshots at a shooting range or an action film at the theatre. The location data can also be used to determine that a user is filming a fight of a wrestling match in an arena or filming a street fight. 
     In addition, information from the user&#39;s social media page can analyze the text, video, images to determine the user&#39;s likes/dislikes. This information can be leveraged to increase the confidence level that a user is filming a particular activity. The cognitive processing of social media profiles includes determining the activities present on a user social media profile. In addition, image analysis, pattern recognition, text and sentiment analysis to determine data such as age, gender, preferences, like/dislikes, etc. Also, user entered preferences on preferred activities can be used to determine the user&#39;s sensitivities for extreme scenarios and activities. Externally available information includes local laws, restricted areas, public parks, restaurants businesses, and the like can be obtained and used in determining whether the content places the user in any harm. 
     In one or more embodiments of the invention, a user can be prompted to redirect the live stream data from a first channel based on the activity and the contextual data. A prompt is provided to the user on the user device. The prompt can include options for the user to redirect the live stream to another channel or the user has the option to ignore the prompt. In one or more embodiments of the invention, the user can select a different contact to redirect the live feed. The system  400  can be configured to automatically connect the “in case of emergency” (ICE) contact with the user based at least in part on the emergency situation and the predetermined ICE contacts of the user. In another embodiment, users can opt-in to the live video anomaly detection system described herein, and the redirection can be performed automatically without providing a prompt to the user. For example, in the event the user is streaming and detecting an emergency situation, the channel redirection can be automatically redirected to a different channel. 
     The method  700  at block  708  provides redirecting, the live stream from a first channel based on the activity and the contextual data to a different channel and simultaneously maintaining the live stream data on the first channel. In the event the user selects from the prompt to redirect the live stream, the live stream can be transferred to one or more other channels such as a channel for emergency responders, authorities, emergency contact list, guardians, etc. After the live stream is redirected, the user maintains the capability to record the live stream while simultaneously providing a live feed to the other channel. 
     In one or more embodiments of the invention, the live stream is configured to buffer and transmit a portion of the live stream prior to the user selecting another channel to redirect the live stream. In a non-limiting example, the system  400  can record the previous 30 seconds of video and include the recorded content in the redirected feed. 
       FIG. 8  depicts a computer program product  800  in accordance with an embodiment that includes a computer readable storage medium  802  and program instructions  804  is generally shown. 
     The techniques described herein provide improvements over the prior art by allowing a live stream feed to continue while having the capability to simultaneously transfer the live stream to another appropriate channel. In addition, the techniques include real-time analysis of the live stream feed, contextual information, and respective user profiles to prompt users to redirect the live stream feed. 
     The technology described herein can be applied to other live stream applications such as closed caption TVs, body cameras, and the like. Also, this technology can be applied to Internet of Things (IoT) mesh networks or other devices to enhance a confidence level or tolerance level in the surrounding events by the devices within proximity to the user device providing the live feed wherein the proximity can be detect by a wireless signal strength or a shared network address of an access point or other techniques. The technology can be configured to automatically connect the “in case of emergency” (ICE) contact with the user based at least in part on the emergency situation. 
     The technical benefits and effects of the invention include anomaly detection within a live stream and a technique to intuitively select additional channels to transfer the live stream factoring in contextual information and user specific sensitivities/preferences. 
     The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention. 
     The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages.
