Abstract:
The technology disclosed relates to identifying and notifying a user of nearby attendees at a mega attendance event who are in user&#39;s social graph by comparing the user&#39;s social graph to a list of event attendees. The identified attendees can be stratified into social graph tags that annotate, categorize and prioritize other users in the user&#39;s social graph. The technology disclosed also relates to identifying and notifying the user of nearby attendees of sessions at the event who meet introduction preferences of the user by finding matches between introduction preference attributes specified by the user and attributes of the attendees provided by the list of event attendees.

Description:
RELATED APPLICATION 
       [0001]    The application claims the benefit of U.S. provisional Patent Application No. 61/814,468, entitled, “Peer-to-Peer Enablement,” filed on Apr. 22, 2013. The provisional application is hereby incorporated by reference for all purposes. 
     
    
     BACKGROUND 
       [0002]    The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed inventions. 
         [0003]    The technology disclosed relates to enablement of new features embedded in downloaded software. In particular, it relates to passing enablement of a new feature from one user to the next by personal, proximate contact, in contrast to centralized or distantly email conveyed enablement of hidden features already present in an application. 
         [0004]    Software can be downloaded that requires an unlock code to enable features or to extend operation of the software beyond a trial period. It can be convenient for a software vendor to distribute code that contains a complete feature set and enable only selected features for which the customer has paid. Unlocking features is controlled by a central licensing server. A unique code or a hash of a code plus the user identifier (ID) is provided by the licensing server and used by the installed code to unlock already installed features. This is often called a license key. It may be short enough to be typed by a user or it may be so long that it needs to be cut and pasted or loaded as a file. 
         [0005]    Unlocking features has been depersonalized because automation scales. The less personal, the more efficient. 
         [0006]    An opportunity arises to reverse the whole approach, to personalize feature activation. Improved user experience and engagement and higher user satisfaction and retention may result. 
       SUMMARY 
       [0007]    The technology disclosed relates to enablement of new features embedded in downloaded software. In particular, it relates to passing enablement of a new feature from one user to the next by personal, proximate contact, in contrast to centralized or distantly email conveyed enablement of hidden features already present in an application.

     DETAILED DESCRIPTION 
       [0015]    The following detailed description is made with reference to the figures. Sample implementations are described to illustrate the technology disclosed, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize a variety of equivalent variations on the description that follows. 
         [0016]    Examples of systems, apparatus, and methods according to the disclosed implementations are described in a “conference” context. The examples of conferences and meetings are being provided solely to add context and aid in the understanding of the disclosed implementations. In other instances, examples of occasions for enablement by proximate interaction may include retail store launches, retail promotions, sporting events, concerts, and other events attended by many types of mobile device users. Other applications are possible, such that the following examples should not be taken as definitive or limiting either in scope, context or setting. It will thus be apparent to one skilled in the art that implementations may be practiced in or outside the conference context. 
         [0017]    The technology disclosed relates to using proximate contact to enable features that are disabled or hidden but already present on a mobile device, spreading through a user population like a virus, from user to user. This technology is described borrowing terms from epidemiology, such as “patient-zero device”, “infectious device”, and “susceptible device”. The technology disclosed can be implemented with any population or mixture of computer-implemented mobile system including smart phones, tablets, laptops, computing glasses, personal assistants, wearable computers, and the like. In a home or business, a mobile device could carry enablement to a stationary device at home or the office. 
         [0018]    Initial distribution of applications with disabled or hidden features relies on a computer-implemented system, such as an app store, a database system, a multi-tenant environment, or the like. Moreover, this technology can be implemented using two or more separate and distinct computer-implemented systems that cooperate and communicate with one another. This technology may be implemented in numerous ways, including as a process, a method, an apparatus, a system, a device, a computer readable medium such as a computer readable storage medium that stores computer readable instructions or computer program code, or as a computer program product comprising a computer usable medium having a computer readable program code embodied therein. 
         [0019]    At a conference, the technology disclosed spreads enablement of a pre-installed feature from one or more patient-zero devices that are infectious to susceptible devices. A susceptible device is infected by a feature enablement token. The susceptible device user and the infectious device user can each be given control over conveyance of feature enablement tokens. A feature enablement token is processed to enable at least one disabled or hidden feature and to infect the susceptible device, making it infectious to further susceptible devices. In some implementations, multiple features can be enabled for a convention goer as they attend sessions correlated with or rewarded by various features. The mobile devices can report enablement metadata to an analytics server. The details of enablement metadata can be user controlled. Enablement spreads through convention goers like a made for TV virus. The analytics server allows convention goers to follow the spread of multiple features through the convention population in real time (more closely than the best CDC technology) in more or less detail as dictated by privacy concerns. In some implementations, spread can be geographically mapped at the convention site and beyond. 
         [0020]    At a convention, the patient-zero device can be a mobile device, a stationary device, or a mobile device stationed at a particular location in a conference room. The speaker in a meeting room could hold the patient-zero device and allow everyone within Bluetooth LE range, for instance, to enable feature one on their first mobile device. The infected first mobile devices, with or without user control, could enable feature one on second mobile devices nearby, until proximate interactions in the meeting room enabled the feature for everyone who wanted the feature enabled or everyone whose device had the feature preloaded and auto enablement active. In some deployments, patient-zero infectious devices could be positioned at entrances and exits to the room or at a prominent kiosk. 
         [0021]    Spread of enablement could begin at a predetermined time set in patient zero devices, susceptible devices, or both. Other criteria could control the outbreak of feature enablement. For instance, special bonus feature enablement could be available to a limited number of lucky convention goers. 
         [0022]    Following this example, the conference room could be geo-fenced so that the spread of enablement codes was more or less infectious, more or less user controlled outside the conference room than inside the room. 
         [0023]    In an alternative embodiment, the technology disclosed spreads download enablement tokens used to install a new feature. A live network at the convention combined with content delivery network edge caching could make installation nearly immediate. A less pervasive delivery system might slow spread of enablement tokens until after installation of the new feature. In some implementations, a device that has received an enablement token could be infectious before the feature is symptomatic, before it is downloaded, enabled, or active. 
       Systems and Actors 
       [0024]      FIG. 1  shows example systems and actors  100  that interact to spread enablement of a feature by proximate interaction.  FIG. 1  includes a developer  132 , app store  115 , analytics engine  138 , apps to distribute  114 , and a database of enablement history  118 . These components are linked in communication by a network  145 .  FIG. 1  also includes first and second susceptible devices  176  and  178 , and one or more patient-zero infectious devices  174 . Devices  174 ,  176 , and  178  can communicate through a common relay  165  such as an access point or directly, without relay, as illustrated by lightning comm link connections. These devices can communicate with a broader network  145  by direct connection, such as a cellular or WiMax connection or through one or more relays  165 . 
         [0025]      FIG. 1  shows an environment  108  that includes various actors along with their devices and networks that interconnect the devices. In other implementations, systems and actors  100  may not have the same systems and/or actors as those listed above and/or may have other/different systems and actors instead of, or in addition to, those listed above. The different systems can be combined into single software modules and multiple software modules can run on the same hardware. 
         [0026]    In this environment, some components are linked in communication by a network  145 . Communications network(s)  145  can be any network or combination of networks of devices that communicate with one another. For instance, network  145  can be any one or any combination of Local Area Network (LAN), Wide Area Network (WAN), the Internet, or private networks. Devices can connect to the network via cellular communications, WiMax, WiFi, telephone network, wireless network, mesh network, or wired network. The network can be arranged as a point-to-point network, star network, token ring network, or hub network. Devices can be connected by peer-to-peer connections like Bluetooth, Bluetooth LE, low power WiFi, Near Field Communication (NFC), Z-Wave, ZigBee, or other appropriate configuration. 
         [0027]    The developer  132  prepares and deploys client-side code for mobile devices with hidden or disabled features. The client-side code also can accept downloadable feature modules that can be downloaded at the same time or separately from a main module. Mobile devices typically are tied to an app store  115 . Some mobile devices accept apps exclusively from a designated app store  115 , at least unless hacked, hijacked, or otherwise modified. Other mobile devices prefer an app store  115  but also accept apps from other sources. In some implementations, the app store can be implemented using varying types of computers such as a workstation, server, computing cluster, blade server, server farm, or any other data processing system or computing device. The engine can be communicably coupled to the databases via a different network connection. 
         [0028]    Apps to distribute  114  can be stored by or on behalf of the app store  115 , developer  132 , or both. The data stores and databases used with the technology described use tangible memory that can be organized as relational database management systems (RDBMSs), object oriented database management systems (OODBMSs), distributed file systems (DFS), no-schema databases, file structures, or any other data storing systems. Tangible memory used for storing data can be rotating or nonrotating. Examples of rotating memory are hard disk drives and optical drives. Examples of nonrotating memory are SRAM, NRAM, DRAM, flash memory, and SSD drives. In this application, tangible memory is not meant to include transitory signals subject to the Federal Circuit rule of In re Nuijten. 
         [0029]    The environment illustrated includes an analytics engine  138 . This analytics engine  138  may include a monitoring component that receives messages reporting feature enablement or infection. In some implementations, a separate monitoring server that does not appear in the figure may be part of the system. The analytics engine  138  can be implemented using varying types of computers such as a workstation, server, computing cluster, blade server, server farm, or any other data processing system or computing device 
         [0030]    Analytics engine  138  receives reporting messages. These reporting messages may include metadata such as the location of the device receiving enablement, the location of the device providing enablement, unique identification of either the devices, a date and time stamp for the enablement (which may be different from the date and time that the corresponding reporting messages received), or other descriptive information. The analytics engine  138  summarizes and provides displays of this information. In simple case, the summary is a count of devices receiving enablement. The count could be updated in real-time or periodically. In more elaborate case, geo-tagging information is received and the geographic spread of enablement is depicted on a map or graph. The forms of graph or visual display used in epidemiology can be applied by the analytics engine  138 . 
         [0031]    Using analytics and logs, a transmission graph may be generated that details how the feature was passed from person to person. Similar to a viral transmission graph, the feature enablement percentage of the general user population may grow from 0% towards 100%. Using the transmission graph, conclusions may be drawn near spikes in the transmission rate. For example, the graph may show spikes in transmission rate that correlate to lunch periods, dinner events, and evening parties where there is a broad pollination of users. Other types of visual presentations of transmission data may be generated to show the progress of feature enablement through peer-to-peer transactions. 
         [0032]    A data visualization of successful transactions may be generated based on a log of the indications received from the plurality of user devices. The data visualization may be presented as a transmission graph over time, in one embodiment. In another embodiment, events may be combined into the transmission graph such that the events are displayed as an overlay over the transmission graph. 
         [0033]    Data used by the analytics engine  138  can be stored in a database of enablement history  118 . As with the store of apps to distribute, many types of alternative tangible memory can be used to store this data. In this application, tangible memory is not meant to include transitory signals subject to the Federal Circuit rule of In re Nuijten. 
         [0034]      FIG. 1  also includes first and second susceptible devices  176  and  178 , and one or more patient-zero infectious devices  174 . The susceptible devices or mobile devices of any of the types described above. Client-side code running on susceptible devices receives enablement tokens or other infectious messages as further described elsewhere. Susceptible client-side code is transformed into infectious client-side code. One or more patient-zero infectious devices  174  start out as infectious to susceptible devices. 
         [0035]    In addition to devices  174 ,  176 , and  178  communicating directly, without relay, or through a common relay  165  these devices can communicate with a broader network  145  by direct connection, such as a cellular or WiMax connection or through one or more relays  165 . 
         [0036]    Proximate interaction between devices is further described in the context of other figures. 
         [0037]      FIG. 2  is a high-level block diagram of the device  270  running an infection engine  220  and at least one app  240 . The device  270  illustrated is a susceptible device that includes an apt  240  with feature code  244  and a mechanism for feature enablement  242 . A patient-zero infectious device can be somewhat simpler, because it may not include an app  240 . In  FIG. 2 , a mobile computing device  270  runs many components, most of which are not illustrated. Infection engine  220  running on the device  270  includes components that handled message processing  222  and infectious state tracking  224 . The message handling  222  processes messages pursuant to connections with other devices. These messages may include an enablement token or other infectious message. A susceptible device can receive an infection via the message processing component  222 . When an infection takes place, the infectious state tracking  224  transformed the device from the susceptible device into an infectious device. The message processing  222  also conveys at least part of the message to feature enablement  242  of the app  240 . 
         [0038]    The app  240  begins with feature code  244  which is not enabled or is hidden. In some implementations, the user may have hidden feature code  244  without knowing what the code is capable of doing. At a convention, a user might hear from the speaker about new features that are available by enabling hidden code. Either as part of an app  240  or as a component that interacts with multiple apps  240 , feature enablement  242  processes incoming messages to selectively enable feature code  244 . 
       Infection Vectors 
       [0039]      FIGS. 3-4  depict different communication schemes by which proximate interaction can propagate feature enablement from a patient zero device  174  through first devices  176   a,    176   b,    176   c  onto second devices  178   d - 178   i.  In  FIG. 3 , the client-side software is distributed by the App Store  115  to multiple devices  174 ,  176 ,  178 . Different versions of the software may be distributed to patient zero devices  174 , as opposed to susceptible devices  176 ,  178 . It is possible for patient zero devices  174  to be infectious without actually having a particular feature enabled. It is expected that first and second devices  176 ,  178  will have a desired feature that is enabled when they become infected.  FIG. 3  illustrates direct communications between devices with lightning bolts. This means some kind of wireless connection. Most wireless connection involves radio waves. Other forms of electromagnetic radiation, such as light, can be used, either for infrared communications, as used by remote control units, or 1D or 2D scan codes, such as used by TSA at airports for paperless boarding passes. 
         [0040]      FIG. 4  depicts a second communication scheme in which devices share a common relay  165 . Sharing a common relay allows use of alternative communication modes such as Wi-Fi, while maintaining proximate interaction. Connection to a common relay  165  may define sufficient proximity or may be combined with additional criteria, such as matching colors, figures or codes being displayed on infectious and susceptible devices. One example of requiring a match between colors and patterns displayed on two mobile devices is the SLIP™ application produced by YODEL CODE™. See www.yodelcode.com/slip as of Apr. 17, 2014. Another criteria that could be used is detection of a received signal strength above a certain threshold on a second radio used by the mobile devices, separate from Wi-Fi. Another criteria that can be used is detected location. The location can be resolved by GPS location, Wi-Fi location, such as using SKYHOOK™, or any other location resolution method. It may be required that devices be within a certain distance. A further criteria that can be used is bumping two devices together, combining timing of accelerometer readings with another indication of proximity. 
         [0041]    While the connection between devices in  FIG. 4  is less direct than in  FIG. 3 , the infection vector, indicated by a dashed line and open headed arrow remains the same as the direct connection infection vector indicated by lightning bolts. 
         [0042]    Release of features may be enabled through a social activation technique facilitated by administrators of the system. Specific features may be tied to specific types of peer-to-peer transactions, in one implementation. In another implementation, a feature may only be activated if a pre-defined rule is satisfied, such as completing five peer-to-peer transactions (e.g., a bump between two mobile devices). In other implementation, peer-to-peer feature enablement may be used as part of a gamification of an application&#39;s usage such that points may be earned based on peer-to-peer transactions. 
       User Control 
       [0043]      FIG. 5  illustrates infectious and susceptible device  514 ,  516  interfaces that can be used to confirm sending and receiving a first feature enablement. One or both of these interfaces can be made available to allow users control of enablement. These are conceptual interfaces that may be enhanced by colors, patterns, pictures, codes or other identifiers for two users to match. The infectious device  514  in this example indicates the device to which enablement is being transferred  524 , the feature being enabled  534 , and asks the user to accept or cancel the transfer  544 . In other enablement modes, the infectious device enable features on any other device that is willing, any other device that can match the color, pattern, picture or code displayed on device  514 , or any other device within a threshold distance. As a proximate interaction distance, the threshold can be on the order of zero feet (as in a bump) to 30 feet (probably within view.) Threshold distances of 0-6 feet, 0-10 feet, or 0-15 feet all are supported by ranges of personal interaction in various settings. 
         [0044]    The susceptible device  516  in  FIG. 5  indicates the device from which enablement is being received  526 , the feature being enabled  536 , and asks the user to accept or decline the enablement  546 . 
         [0045]    Not illustrated, the client side software of an infectious device can be further capable of allowing the user to remedy an infectious state if they do not like the feature that they enabled. That is, they can reverse their infectious state so that their device will not pass on enablement of the feature. This decision can be tracked by the analytical engine. 
       Flowchart of Events Leading to Infectious Enablement of Features 
       [0046]      FIG. 6  is a flowchart of one implementation on the infectious device and susceptible device sides of a transmission vector. The steps in the flowchart can be viewed or described from the perspective of a server, infectious device, or susceptible device. Not all of the steps need to be practiced to take advantage of the technology disclosed. While the steps are described with respect to a system and hardware such as depicted in  FIG. 1 , the methods illustrated in the flow charts do not depend on any particular hardware. Similar methods that leverage the technology disclosed may combine steps that are separate in the flowcharts, add supplemental steps, or subdivide the steps illustrated. 
         [0047]    The infectious device portion of the flowchart is steps  610 - 640 . At step  610 , an infectious version of client-side software is downloaded onto a patient zero device. An app store  115  or other installation server or system can select among apps to distribute  114  and cause the infectious version of the software to be provided to the device. 
         [0048]    At step  620 , the infectious device connects to a susceptible device. This may happen automatically or may require a connection protocol enforced by the operating system or the infection engine  220 . For instance, Bluetooth LE can establish a connection without requiring confirmation by either device user. In contrast, traditional Bluetooth usually is implemented with at least one side of the connection selecting a connection to establish. Traditional Bluetooth sometimes is implemented using confirmation of matching between the systems or entry of a code on one or both sides of the connection. 
         [0049]    At step  630 , the infection engine on the infectious device can receive a signal from a user of the device or from a user of the susceptible device that confirms sending the feature enablement token or other message to cause feature enablement on the receiving device and to change the receiving device from susceptible to infectious. 
         [0050]    At step  640 , the infectious device actually transmits the feature enablement token or other message to cause feature enablement. 
         [0051]    The susceptible device portion of the flowchart is steps  650 - 690 . At step  650 , a susceptible version of client-side software is downloaded onto a susceptible device. This susceptible device can have at least one disabled or hidden feature. An app store  115  or other installation server or system can select among apps to distribute  114  and cause the susceptible version of the software to be provided to the device. 
         [0052]    At step  660 , the susceptible device connects to an infectious device. This may happen automatically or may require a connection protocol enforced by the operating system or the infection engine  220 . 
         [0053]    At step  670 , the infection engine on the susceptible device can receive a signal from a user of the device that confirms acceptance of the feature enablement token or other message to cause feature enablement on the receiving device. Acceptance can automatically change the receiving device from susceptible to infectious. In some implementations, the receiving user could have been given separate control over enabling the feature and over becoming infectious. 
         [0054]    At step  680 , the susceptible device receives and implements the feature enablement token or other message to cause feature enablement. The app  240  invokes feature enablement  242  to enable feature code  244 . As indicated above, in some implementations, feature enablement may require an additional step of downloading the feature code using the enablement token or other message as authorization. 
         [0055]    At step  690 , the receiving device changes from susceptible to infectious. The Infection engine  220  invokes infectious state tracking  224  to for this change. 
       Computer System 
       [0056]      FIG. 7  is a block diagram of an example computer system  700  used by an infectious or susceptible device.  FIG. 7  is a block diagram of an example computer system, according to one implementation. Computer system  710  typically includes at least one processor  772  that communicates with a number of peripheral devices via bus subsystem  750 . These peripheral devices can include a storage subsystem  726  including, for example, memory devices and a file storage subsystem, user interface input devices  738 , user interface output devices  778 , and a network interface subsystem  776 . The input and output devices allow user interaction with computer system  710 . Network interface subsystem  776  provides an interface to outside networks, including an interface to corresponding interface devices in other computer systems. 
         [0057]    User interface input devices  738  can include a keyboard; pointing devices such as a mouse, trackball, touchpad, or graphics tablet; a scanner; a touch screen incorporated into the display; audio input devices such as voice recognition systems and microphones; and other types of input devices. In general, use of the term “input device” is intended to include all possible types of devices and ways to input information into computer system  710 . 
         [0058]    User interface output devices  778  can include a display subsystem, a printer, a fax machine, or non-visual displays such as audio output devices. The display subsystem can include a cathode ray tube (CRT), a flat-panel device such as a liquid crystal display (LCD), a projection device, or some other mechanism for creating a visible image. The display subsystem can also provide a non-visual display such as audio output devices. In general, use of the term “output device” is intended to include all possible types of devices and ways to output information from computer system  710  to the user or to another machine or computer system. 
         [0059]    Storage subsystem  726  stores programming and data constructs that provide the functionality of some or all of the modules and methods described herein. These software modules are generally executed by processor  772  alone or in combination with other processors. 
         [0060]    Memory  722  used in the storage subsystem can include a number of memories including a main random access memory (RAM)  734  for storage of instructions and data during program execution and a read only memory (ROM)  732  in which fixed instructions are stored. A file storage subsystem  736  can provide persistent storage for program and data files, and can include a hard disk drive, a floppy disk drive along with associated removable media, a CD-ROM drive, an optical drive, or removable media cartridges. The modules implementing the functionality of certain implementations can be stored by file storage subsystem  736  in the storage subsystem  726 , or in other machines accessible by the processor. 
         [0061]    Bus subsystem  750  provides a mechanism for letting the various components and subsystems of computer system  710  communicate with each other as intended. Although bus subsystem  750  is shown schematically as a single bus, alternative implementations of the bus subsystem can use multiple busses.

       Particular Implementations 
       [0063]    In one implementation, a method is described from the perspective of one or more servers distributing client-side software with features that are not enabled or are hidden. The method includes making enablement of software features contingent on social interaction. This includes delivering for installation to first and second devices susceptible client-side code with at least a first feature in a disabled or hidden state and delivering for installation to third devices infectious client-side code. The first feature can be either enabled or not enabled in the infectious client-side code. Practicing this method, the client-side code makes proximate interaction of a first susceptible device running the susceptible client-side code with a third device running the infectious client-side code capable of enabling the first feature on the first device and of making the first device infectious to other second devices running the susceptible client-side code that have not yet interacted with a device running the infectious client-side code. 
         [0064]    This method and other implementations of the technology disclosed can include one or more of the following features and/or features described in connection with additional methods disclosed. In the interest of conciseness, the combinations of features disclosed in this application are not individually enumerated and are not repeated with each base set of features. The reader will understand how features identified as implementations in this section can readily be combined with sets of base features. 
         [0065]    In some implementations, the method is enhanced by receiving activation spread messages as the enabled state of the first feature spreads by proximate interaction between susceptible devices and infectious devices; and repeatedly reporting at least a count of infected devices as the enabled state of the first feature spreads. 
         [0066]    In some implementations, the method is enhanced by receiving activation spread locations and times; correlating the locations and times with real world events; and repeatedly reporting at least a pattern of the spread. 
         [0067]    In some implementations, the method is enhanced by two or more features in the susceptible client-side code; and requiring different infection vectors to activate respective features.

         [0069]    In some implementations, the method is enhanced by including the susceptible client-side code requiring consent by a user of a first or second device to the proximate interaction with an infectious device before the first or second device enables the feature and becomes infectious. 
         [0070]    In some implementations, the method is enhanced wherein the client-side code on the first and second devices are mobile devices is capable of invoking direct device-to-device communications between the susceptible and infectious devices without relay.

         [0073]    In some implementations, the method is enhanced wherein the direct device-to-device communications uses a 1D or 2D bar code. 
         [0074]    In some implementations, the method is enhanced wherein the first and second devices are mobile devices and the proximate interaction includes bumping together a respective pair of infectious and susceptible devices. 
         [0075]    In some implementations, the method is enhanced wherein the first and second devices are mobile devices and the proximate interaction includes relayed communication through a single access point coupled wirelessly directly to a respective pair of infectious and susceptible devices. 
         [0076]    In some implementations, the method is enhanced wherein the client-side code on at least one of devices is capable of calculating an approximate distance between the respective pair of infectious and susceptible devices and requiring the distance to be less than a predetermined threshold for a proximate interaction to take place. 
         [0077]    Another implementation describes a system that makes hardware capable of carrying out any of the methods described. The system includes client-side code deployed to first, second and third devices, wherein the client-side code makes the first, second and third devices capable of interactions including wherein the client-side code on the first devices and second devices is susceptible client-side code with at least a first feature in a disabled or hidden state; wherein the client-side code on the third devices is infectious client-side code; proximate interaction of a first susceptible device running the susceptible client-side code with a third device running the infectious client-side code enables the first feature on the first device; and makes the first device infectious to other second devices running the susceptible client-side code that have not yet interacted with a device running the infectious client-side code.
