Title: Wireless authentication systems and methods

Description:
CROSS-REFERENCE TO RELATED APPLICATION AND PRIORITY CLAIM 
     This application is a continuation of U.S. patent application Ser. No. 16/931,659, filed 17 Jul. 2020, entitled “WIRELESS AUTHENTICATION SYSTEMS AND METHODS,” the entire contents and substance of which is incorporated herein by reference as if fully set forth below. 
    
    
     FIELD 
     The present disclosure relates to keyless systems, and, more particularly, to systems and methods for wireless authentication. 
     BACKGROUND 
     Traditionally, activating a secured system requires physical interaction. For example, entering a locked room requires interacting with a physical lock using a physical key. Similarly, motor vehicles utilize an ignition lock that required a physical ignition key to start the motor vehicles&#39; engines. More recently, the use of a physical key has been replaced with wireless authentication systems. For certain secured facilities, an ID badge or security fob may be capable of emitting an authentication signal to open doors. Similarly, in motor vehicles, a keyless ignition system can replace the use of a physical key by using a fob that interacts with a receiver in the motor vehicle. When a “start” button is pushed, the motor vehicle broadcasts a request signal, and the fob responds with an authentication response. After the authentication response is received, the motor vehicle validates the response and starts the motor vehicle&#39;s engine. 
     Wireless authentication provides several benefits over physical authentication systems. First, wireless authentication is more convenient as a user can be authenticated without physically interacting with the system. For example, with a motor vehicle, a user can leave a fob in their pocket or purse to start the vehicle. Additionally, wireless authentication allows the use of advanced security measures to protect the wireless authentication key from being compromised. For example, since the wireless authenticator exchanges encrypted or secret information, it cannot be easily replicated. 
     One drawback of wireless authentication systems, however, is that they respond to anyone having the authenticator. For instance, if a third-party steals an ID badge, they can access the secured area. Similarly, if a car&#39;s fob is stolen or copied, the vehicle will respond to the possessor of the fob as if the possessor were a legitimate user. Therefore, there is a need for improved systems and methods for wireless authentication.

     DETAILED DESCRIPTION 
     The present disclosure can be understood more readily by reference to the following detailed description of one or more example embodiments and the examples included herein. It is to be understood that embodiments are not limited to the example embodiments described within this disclosure. Numerous modifications and variations therein will be apparent to those skilled in the art and remain within the scope of the disclosure. It is also to be understood that the terminology used herein is for describing specific example embodiments only and is not intended to be limiting. Some example embodiments of the disclosed technology will be described more fully hereinafter with reference to the accompanying drawings. The disclosed technology might be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. 
     Aspects of the present disclosure relate to systems and methods for providing enhanced wireless authentication. In an embodiment, an interference unit responds to a request signal (e.g., authentication request) to “jam” or otherwise interfere with the response signal from the authenticator. The interference unit responding together with an authentication key “confuses” the authentication system, making it unable to verify the response signal (e.g., authentication response). For example, when a “start” button is pushed, the motor vehicle broadcasts a request signal. As discussed above, when the fob receives the request signal, it outputs a wireless response. The interference unit likewise receives the request signal broadcast from the motor vehicle and outputs its own wireless response at or about the same time. Thus, the motor vehicle receives a response from both the fob and the interference unit around the same time, or in quick succession and the motor vehicle is unable to authenticate the fob&#39;s response signal due to the additional signal from the interference unit. In some cases, the interference unit could detect the wireless response from the fob and, in response, outputs an interference signal (e.g., an interference signal, modification signal, etc.). Thus, the motor vehicle may still receive a response from both the fob and the interference unit around the same time, or in quick succession, and the motor vehicle is unable to authenticate the fob. By outputting the response or interference signal only in response to detecting the request signal and/or response signal from the authentication device, the interference unit may have enhanced battery life. 
     In some cases, the interference unit may receive wireless instructions (e.g., WiFi, Bluetooth, 4G, 5G or telephony signal) that instruct the interference unit to be in an active state (i.e., output response or interference signals) or an inactive state (i.e., do not respond to request or response signals). In such a way, the interference unit may be remotely configured to deny an authentication of a user. In an embodiment, the interference unit may be able to exchange short-range instructions with an external controller. For example, an external controller could exchange data with a remote server and control an activation state of the interference unit utilizing short-range communication (e.g., Bluetooth Low Energy, any of the IEEE 802.15.4 or IEEE 802.11 based protocols, etc.). Thus, the interference unit could use minimal power while enabling remote configuration to deny authentication of the user. 
     An interference unit may respond to a signal initiated by an authentication key to “jam” or override, or otherwise interfere with the signal from the authentication key. For example, certain motor vehicles have a remote start feature. With the remote start feature, a user presses a start button on a key fob and remotely starts the motor vehicle. In such cases, the interference unit may detect a beginning portion of the start signal from the fob and output an interference signal with a latter portion of the start signal. 
     The interference unit outputting together with an authentication key “confuses” the authentication system, making it unable to verify the response signal (e.g., authentication response). For example, when a “start” button is pushed, the motor vehicle broadcasts a request signal. As discussed above, when the fob receives the request signal, it outputs a wireless response. The interference unit likewise receives the request signal broadcast from the motor vehicle and outputs its own wireless response at or about the same time. Thus, the motor vehicle receives a response from both the fob and the interference unit around the same time, and the motor vehicle is unable to authenticate the fob&#39;s response signal due to interference from the interference unit or from the content of the interference message. In some cases, the interference unit could detect the wireless response from the fob and, in response, outputs an interference signal. Thus, the motor vehicle may still receive a response from both the fob and the interference unit around the same time, and the motor vehicle is unable to authenticate the fob. By outputting the response or interference signal only in response to detecting the request signal and/or response signal from the authentication device, the interference unit may have enhanced battery life. Although certain embodiments discuss the use of a key fob, one of ordinary skill will recognize in light of the present disclosure that the key fob could be, for example, a mobile phone, tablet, or other communication or multifunction device set-up to output an authentication response. Additionally, while key fob and/or authentication key may be used, this is merely an example and one of ordinary skill will recognize in light of the present disclosure that the interference unit  210  can operate with various authentication devices. 
     Aspects of the present disclosure will now be discussed with reference to the figures. While aspects of the present disclosure are discussed in relation to wireless authentication for user access or use of a keyless ignition system, these are merely examples. One of ordinary skill will recognize that aspects of the present disclosure may be used in various wireless authentication systems. 
       FIG. 1  illustrates an example of wireless authentication without an interference unit or with an interference unit being inactive. At  100   a , user  130  approaches door  190 . Door  190  is associated with authentication terminal  150 . Authentication terminal  150  may have authentication activator  160  that instructs authentication terminal  150  to output an authentication request. As non-limiting examples, authentication activator  160  may be a button-switch or a presence sensor that detects the presence of user  130 . However, these are merely examples, and authentication activator may be implemented in various forms as would be understood by one of ordinary skill. Additionally, in some cases, authentication terminal  150  may repeatedly or periodically output an authentication request. 
     At  100   b , authentication terminal  150  outputs authentication request  155  (e.g., in response to a signal from authentication activator  160 ). If wireless authentication key  120  is present (e.g., in user&#39;s  130  hand or pocket), at  100   c , wireless authentication key  120  outputs authentication response  125  in response to the request  155 . At  100   d , authentication terminal  150  validates authentication response  125  and opens doors  190 . 
       FIG. 2  is a block diagram of an example wireless authentication environment  200 . Wireless authentication environment  200  includes authentication terminal  150 , wireless authentication key  120 , and interference unit  210 . Wireless authentication environment  200  may also include authentication activator  160  and/or server  270 . Authentication terminal  150  may output an authentication request (e.g., in response to instructions from authentication activator  160 ). Wireless authentication key  120  may output an authentication response to authentication terminal  150 . If interference unit  210  is not present or in an inactive state, authentication terminal  150  may validate the authentication response to authorize wireless authentication key  120 . 
     However, if interference unit  210  is present and active, interference unit  210  may output an interference signal (e.g., an interference signal) in response to the authentication request (e.g., a low-frequency request signal). For example, interference unit  210  may output the interference signal at a sufficient magnitude to substantially render the authentication terminal  150  unable to correctly receive the authentication response. In some cases, the interference signal may be a similar or greater amplitude as the authentication response as received by authentication terminal  150 . If a directionality of transmitter antennas is asymmetrical, the antenna may be positioned such relative to the authentication terminal  150  to provide a sufficiently powerful interference signal. In some cases, interference unit  210  can control the frequency spectrum of the interference signal to match characteristics of the authentication terminal  150  (e.g., approximately match expected frequency and amplitude of the authentication response). For example, interference unit  210  can modulate a frequency of the interference signal in a specific way to match what is expected by the authentication terminal  150 . 
     In other cases, the interference signal may interfere with, contradict, override, or otherwise alter portions of authentication response as it appears to be received by authentication terminal. Accordingly, the combination of the interference signal and the authentication response received by the authentication terminal  150  may provide different information than the authentication response received alone, making the reception invalid. In some cases, data from interference signal may comingle with data from authentication response as it is received by authentication terminal  150 . In such cases, authentication terminal may be unable to differentiate the data contained in interference signal from the data contained in authentication response, making the authentication response unintelligible. 
     Interference unit  210  may be configured to detect an authentication request from authentication terminal  150  within a particular frequency range and respond thereto. For example, authentication terminal  150  may output the authentication request within one or more predetermined frequency range(s) or channel(s). One of ordinary skill will recognize that various signals may be transmitted within the predetermined frequency range(s), both by authentication terminal  150  and other external devices. Accordingly, interference unit  210  may be configured to identify and/or decode signals within the predetermined frequency range(s) to determine whether the signal is from authentication terminal  150  and/or corresponds to an authentication request. In some cases, interference unit  210  can be configured to determine how to detect a signal from authentication terminal  150  and/or an authentication key  120  (e.g., which frequency bands, modulation patterns, power levels to use, what authentication terminal  150  identifier(s) to look for in the incoming messages, etc.). In some cases, authentication terminal  150  and/or an authentication key  120  may operate over a plurality of frequency ranges, channels or spectrums either simultaneously or optionally. Additionally, interference unit  210  can be configured to customize an interference signal to be effective with a specific authentication terminal  150 /authentication response. For example, interference unit  210  can create interference signals with various parameters such as transmit frequency channels, signal modulation, signal strength, signal duration, exact or partial data to be transmitted, etc. 
     In some cases, the predetermined frequency range(s) could include one or more bands from among 315 MHz, 433 MHz, and 868 MHz, and/or 915 MHz. However, the present disclosure is not so limited and, in some cases, interference unit  210  could operate in ranges similar to other ISM bands (e.g., 2.4 GHz and/or 5 GHz bands) as well as bands utilized by Ultra Wide Band (UWB) chips. 
     Additionally, in some cases, authentication key  120  and/or authentication terminal  150  may utilize different frequencies. For example, authentication terminal  150  may utilize a low frequency, (e.g., 125 kHz) while authentication terminal  150  may operate at a higher frequency (e.g., 315 MHz, 433 MHz, 868 MHz, 915 MHz, 2.4 GHz, etc.). Furthermore, authentication key  120  and/or authentication terminal  150  may use frequency hopping (e.g., defined, logic-controlled, random, or pseudo-random frequency hopping) to transmit authentication request and/or authentication response. Accordingly, in some cases, override unit  210  may monitor a plurality of channels or bands. Additionally, override unit  210  can output interference signal across a plurality of channels either simultaneously or in quick succession to interfere with or otherwise disrupt the authentication process. As a non-limiting example, if the authentication response is 6 milliseconds and includes frequency hopping across 3 channels, override unit  210  could output interference signal on each channel for 2 millisecond each in rapid succession. However, this is merely an example and, in some cases, interference unit  210  could be configured to mimic the frequency hopping of authentication terminal  150 /authentication key  120  so that interference signal can mimic the authentication response. 
     Additionally, in some cases, interference unit  210  may have a plurality of output antennas of overlapping ranges. While the interference signal is broadcast in a first channel via a first antenna, a second antenna could be tuned to a next frequency in the frequency hopping sequence. Thus, when interference signal should broadcast over this next frequency, it may be immediately broadcast using the second antenna, thus minimizing tuning delays. 
     Interference unit  210  may include one or more receivers, one or more transmitters, and/or one or more transceivers. The receiver may detect signals (e.g., authentication request and/or authentication response) and the transmitter may broadcast signals (e.g., interference signal). The one or more receivers may be programmable or adjustable to detect signals within different frequency ranges and/or across different bands or channels. Similarly, the one or more transmitters may be programmable or adjustable to output signals within different frequency ranges and/or across different bands or channels. Interference unit  210  may also include a controller for controlling the receiver and transmitter, for example to tune one or more antennas of the receiver and transmitter and/or control output of the transmitter. Interference unit  210  may be configured to communicate with additional external systems. 
     In some cases, server  270  may communicate with interference unit  210 , for example, over a wireless data channel (e.g., cellular, 4G, 5G, etc.). Server  270  may set an activation state of interference unit  210 . In an active state, interference unit  210  may interfere with the authentication of authentication key  120 . In an inactive state, interference unit  210  may not interfere with the authentication of authentication key  120 . Accordingly, an additional layer of security may be provided by remotely controlling the interference unit  210  through server  270 . However, this is only an example, and one of ordinary skill, in view of the present disclosure, would understand that various other remote or local systems may control interference unit  210 . In some cases, interference unit  210  activate or deactivate based on lock commands. For example, with a motor vehicle, doors may be locked or unlocked remotely with a fob (e.g., authentication key  120 ) or through the use of cellular communication. Interference unit  120  may “listen” for an unlock command from the fob and/or a cellular device, and switch to an inactive state. Likewise, interference unit  120  may “listen” for a lock command from the fob and/or a cellular device, and switch to an inactive state. As another example, interference unit  210  may be active during periods of time (e.g., set to interfere with response signals during the night or specific days of the week) or specific locations (e.g. by use of geo-fences) when no authentication is desired. Additionally, interference unit  210  can be configured to determine when to output interference signals (e.g., when interference unit  210  is “on”). This can include, for example, awaiting specific instructions from an external system (e.g., server  270  and/or interference controller  640  as discussed below with reference to  FIG. 6 ) and/or having a set (or preset) rule or algorithm for determining when authentication is allowed/override is disabled (e.g., based on specific geo-fencing, time of the day, external temperature, etc.). 
     Server  270  may also communicate with interference unit  210  to establish parameters for detecting an authentication request and/or an authentication response (e.g., frequency, message code), as well as parameters for outputting an interference signal (e.g., frequency, duration, amplitude). In such a way, interference unit  210  may be configurable to adapt to new and/or various authentication terminals  150  and authentication keys  120 . In some cases, interference unit  210  may report tampering attempts to server  270 . Thus, if a malicious user attempts to circumvent interference  210  through physical or electronic manipulation, an alert may be provided to server  270 . Additionally, in some cases, interference unit  210  can detect unusually authentication request/response activity. For example, interference unit  210  would detect authentication requests and, if a number authentication requests are received in short succession when the interference unit is active, override unit  210  could alert server  270  of the repeated attempted authentication (e.g., access or vehicle start). 
     As would be understood by one of ordinary skill, different authentication terminals  150  and authentication keys  120  may operate over different frequency ranges, distances, and/or with different encoding mechanisms. Accordingly, in some cases, interference terminal  210  may be programmed to correspond to specific authentication terminals  150  and/or authentication keys  120 . For example, if interference unit  210  is to be used with a specific motor vehicle, interference unit  210  may be configured to “confuse” the authentication terminal  1500  of the specific motor vehicle make, model, and year. For instance, a vehicle identification number (VIN) of the motor vehicle may be determined, and server  270  may determine the motor vehicle&#39;s make, model, and year and provide configuration instructions to interference unit  210 . Specific vehicle identification may also be used to ensure only this particular vehicle is monitored for controlling access. Specifics of individual vehicle identification may be established during installation of the interference unit  210 . 
       FIG. 3  illustrates an example of wireless authentication within wireless authentication environment  200 . At  300   a , user  130  approaches door  190 . Door  190  is associated with authentication terminal  150 , which controls access to door  190 . Authentication terminal  150  may have authentication activator  160  that instructs authentication terminal  150  to output an authentication request. As non-limiting examples, authentication activator  160  may be a button-switch or a presence sensor. However, these are merely examples, and authentication activator may be implemented in various forms as would be understood by one of ordinary skill. Additionally, in some cases, authentication terminal  150  may repeatedly or periodically output an authentication request. 
     At  300   b , authentication terminal  150  outputs authentication request  155  (e.g., in response to a signal from authentication activator  160 , or periodically on its own). If wireless authentication key  120  and interference unit  210  are both present (e.g., in user&#39;s  130  hand(s) or pocket(s)), at  300   c , in response to the request  155 , wireless authentication key  120  outputs authentication response  125  and interference unit  210  outputs interference signal  315 . Since authentication response  125  and interference signal  315  are output at substantially the same time, potentially from a similar location, authentication terminal  150  receives authentication response  125  and interference signal  315  at approximately the same time. Therefore, authentication terminal  150  is unable to validate authentication response  125 . Accordingly, at  300   d , authentication terminal  150  does not open doors  190 . 
     In some cases, interference signal  315  may be output at a sufficient magnitude to substantially block authentication response  125 . In such cases, authentication terminal  150  may not detect authentication response  125 . In some cases, interference signal  315  may interfere with, contradict, override, or otherwise alter portions of authentication response  125  as it appears to be received by authentication terminal  150 . Because of the apparent changes to authentication response  125 , authentication terminal  150  may be unable to validate authentication response  125 . In some cases, data from interference signal  315  may comingle with data from authentication response  125  as it is received by authentication terminal  150 . In such cases, authentication terminal  150  may be unable to differentiate the data contained in interference signal  315  from the data contained in authentication response  125 , and the data received would not correspond to a valid authentication key. In another case, the interference signal  315  may explicitly or implicitly signal the authentication terminal  150  to invalidate the authentication response  125  sent closely in time to the interference signal  315 . 
       FIG. 4  is a block diagram of an example wireless authentication environment  400 . Wireless authentication environment  400  includes authentication terminal  150 , wireless authentication key  120 , and interference unit  210 . Wireless authentication environment  200  may also include authentication activator  160  and/or server  270 . Authentication terminal  150 , wireless authentication key  120 , authentication activator  160 , and server  170  may operate substantially similar to like elements discussed above with reference to  FIGS. 2 and 3 . For example, authentication terminal  150  may output an authentication request, and authentication key  120  may output an authentication response. If interference unit  210  is not present or inactive, authentication terminal  150  may validate the authentication response. 
     However, if interference unit  210  is present and active, interference unit  210  may output an interference signal in response to the authentication response from authentication key  120  (e.g., instead of or in addition to in response to the authentication request from authentication terminal  150 ). For example, interference unit  210  may respond to a signal in a specific frequency range of authentication key  120 . In response to detecting the signal, interference unit  210  may output the interference signal. Interference Unit  210  may be programmed or configured to ensure that the interference signal is received at the same or overlapping time as the authentication response, before or immediately after it. 
     As discussed above, the interference signal may have a sufficient magnitude to substantially block the authentication response, thus preventing authentication terminal  150  from receiving the authentication response. In other cases, the interference signal may interfere with, contradict, override, or otherwise alter portions of authentication response as it appears to be received by authentication terminal  150 . Accordingly, the combination of the interference signal and the authentication response received by the authentication terminal  150  may provide different information than the authentication response received alone, making the reception invalid. In some cases, data from the interference signal may comingle with data from the authentication response as it is received by authentication terminal  150 . In such cases, authentication terminal  150  may be unable to differentiate the data contained in the interference signal from the data contained in the authentication response, making the authentication response unintelligible. In some cases, the interference signal may explicitly or implicitly signal the authentication terminal  150  to invalidate the authentication response sent closely in time to the interference signal. 
     Interference unit  210  may be configured to detect an authentication response from authentication key  120  within a particular frequency range and respond thereto. For example, authentication key  120  may output the authentication response within a predetermined frequency range. One of ordinary skill will recognize that various signals may be transmitted within the predetermined frequency range, both by authentication key  120  and other external devices. Accordingly, interference unit  210  may be configured to decode signals within the predetermined frequency range to determine whether the signal is from authentication key  120  and/or corresponds to an authentication response. 
       FIG. 5  illustrates an example of wireless authentication within wireless authentication environment  400 . At  500   a , user  130  approaches door  190 . Door  190  is associated with authentication terminal  150 . Authentication terminal  150  may have authentication activator  160  that instructs authentication terminal  150  to output an authentication request. As non-limiting examples, authentication activator  160  may be a button-switch or a presence sensor. However, these are merely examples, and authentication activator may be implemented in various forms as would be understood by one of ordinary skill. Additionally, in some cases, authentication terminal  150  may repeatedly or periodically output an authentication request. 
     At  500   b , authentication terminal  150  outputs authentication request  155  (e.g., in response to a signal from authentication activator  160 ). If wireless authentication key  120  is present (e.g., in user&#39;s  130  hand or pocket), at  500   c , in response to the request  155 , wireless authentication key  120  outputs authentication response  125   a . Then, if interference unit  210  is present and active (e.g., in user&#39;s  130  hand or pocket), at  500   d , in response to detecting a first part of the authentication response  125   a , interference unit  210  outputs interference signal  515 . Thus, at least a portion of authentication response  125   b  and interference signal  515  are output at substantially the same time from a similar location (e.g., from within a certain distance from the authentical terminal  150 ), and authentication terminal  150  receives authentication response  125   b  and interference signal  515  at approximately the same time. Therefore, authentication terminal  150  is unable to validate authentication response  125 . Accordingly, at  500   e , authentication terminal  150  does not open doors  190 . 
     Although  FIGS. 4 and 5  are discussed with reference to an interference unit  210  responding to an authentication response, this is merely an example. In some cases, authentication key  120  may initialize an authentication attempt by outputting an authentication message. In view of the present disclosure, one of ordinary skill would recognize that interference unit  210  could detect and respond to an authentication message originating from authentication key  120  as if it was an authentication response. 
       FIG. 6  is a block diagram of an example wireless authentication environment  600 . Wireless authentication environment  600  includes authentication terminal  150 , wireless authentication key  120 , interference unit  210 , and interference controller  640 . Wireless authentication environment  600  may also include authentication activator  160  and/or server  270 . Authentication terminal  150 , wireless authentication key  120 , and authentication activator  160  may operate substantially similar to like elements discussed above with reference to  FIGS. 2-5 . For example, authentication terminal  150  may output an authentication request, and authentication key  120  may output an authentication response. If interference unit  210  is not present or inactive, authentication terminal  150  may validate the authentication response. 
     However, if interference unit  210  is present and active, interference unit  210  may output an interference signal in response to the authentication request from authentication terminal  150 , the authentication response from authentication key  120 , or both the authentication request and the authentication response, as discussed above with reference to  FIGS. 3-5 . Interference controller  640  may create a connection (e.g., using a short-range type connection such as one based on a Bluetooth standard, IEEE 802.15.4, or the like, using a physical connection) or otherwise broadcast instructions to interference unit  210 . For example, the instructions may control an activation state of interference unit  210 . In some cases, the instructions may configure interference unit  210  to operate with the specific authentication terminal  150  and/or authentication key  120 . 
     As a non-limiting example, interference controller  640  could be a verification device or system. If the verification device determines that the condition is verified, it may control interference unit  210  to deactivate. For example, interference controller  640  could be an in-vehicle breathalyzer (e.g., an alcohol or drug interlock system). In this potential use case, a user would be required to breathe into the breathalyzer before being able to start their vehicle. If the breathalyzer determines that the individual is able to drive, the breathalyzer may signal the interference unit to allow authentication (e.g., for a predetermined period of time following verification). In other cases and at other times (e.g., whenever the breathalyzer does not determine that the individual is able to drive), the authentication may be not allowed. 
     In some cases, server  670  may communicate with interference controller  640 , for example, over a wireless data channel (e.g., cellular, 4G, 5G, etc.). Server  670  may direct an activation state of interference unit  210 , which is relayed by interference controller  640 . One of ordinary skill, in view of the present disclosure, would understand that various other remote or local systems may communicate with interference controller  640 . For example, in some cases, interference controller  640  may be configured to place interference unit  210  in an inactive state during periods of time (e.g., set to interfere with response signals during the night or on the weekend) when no authentication is desired. Interference controller  640  may be fixed near authentication terminal  150  and may have an extended power supply (e.g., either an independent battery or draw from the same power supply as authentication terminal  150 ) compared to interference unit  210 . Thus, interference unit  210  may be remotely controlled while minimizing the size and power consumption of interference unit  210 . In some cases, interference controller  640  may report tampering attempts to server  670 . Thus, if a malicious user attempts to circumvent or uninstall interference controller  640 , an alert may be provided to server  670 . 
     While interference unit  210  and interference controller  640  may be separate devices, this is merely an example. In some cases, interference unit  210  and interference controller  640  may be combined in a single unit. 
       FIG. 7  illustrates an example of wireless authentication within wireless authentication environment  600 . At  700   a , user  130  approaches door  190 . Door  190  is associated with authentication terminal  150 . Authentication terminal  150  may have authentication activator  160  that instructs authentication terminal  150  to output an authentication request. As non-limiting examples, authentication activator  160  may be a button-switch or a presence sensor. However, these are merely examples, and authentication activator may be implemented in various forms as would be understood by one of ordinary skill. Additionally, in some cases, authentication terminal  150  may repeatedly or periodically output an authentication request. 
     At  700   c , authentication terminal  150  outputs authentication request  155  (e.g., in response to a signal from authentication activator  160 ). If wireless authentication key  120  and interference unit  210  are present and interference unit  210  is in an active state, at  700   d , in response to the request  155 , wireless authentication key  120  outputs authentication response  125  and interference unit  210  outputs interference signal  715 . Since authentication response  125  and interference signal  715  are output at substantially the same time from a similar location, authentication terminal  150  receives authentication response  125  and interference signal  715  at approximately the same time. Therefore, authentication terminal  150  is unable to validate authentication response  125 . Accordingly, at  700   e , authentication terminal  150  does not open doors  190 . 
       FIG. 8  is a flowchart  800  of an example method of operating an interference unit (e.g., interference unit  210 ). For ease of description, the flowchart  800  will be discussed with reference to interference unit  210 , but this is merely an example, and one of ordinary skill will recognize, in light of the present disclosure, that the method may be performed by various other devices and in various other environments. At  810 , interference unit  210  determines whether it is in an active state. For example, an activation state of interference unit  210  may be set by server  240 , an interference controller, or by internal controls (e.g., a pre-set schedule or algorithms residing inside of the interference unit  210  that consider all sensor data available to the interference unit  210  when making the activation state determination). If interference unit  210  is in the active state ( 810 -Yes), interference unit  210  waits to detect a signal at  820 . Interference unit  210  may attempt to detect an authentication request from an authentication terminal  150 , an authentication response from authentication key  120 , or both an authentication terminal  150  and an authentication response from authentication key  120 . The detection may be at same, similar or different frequencies. 
     In response to detecting the signal ( 820 -Yes), interference unit  210  outputs an interference signal at  830 . For example, interference unit  210  may output the interference signal at a sufficient magnitude to substantially block the authentication response, thus preventing authentication terminal  150  from receiving the authentication response. In other cases, the interference signal may interfere with, contradict, override, or otherwise alter portions of authentication response as it appears to be received by authentication terminal  150 . In some other cases, it may signal the request to invalidate the message received as the authentication response that was received within close proximity. Accordingly, the combination of the interference signal and the authentication response received by the authentication terminal  150  may provide different information than the authentication response received alone, making the reception invalid. In some cases, data from interference signal may comingle with data from authentication response as it is received by authentication terminal  150 . In such cases, authentication terminal  150  may be unable to differentiate the data contained in interference signal from the data contained in authentication response, making the authentication response unintelligible. 
     After outputting the interference signal, interference unit  210  may determine whether a change in state has occurred at  840  to place interference unit  210  into an inactive state. If no change of state has occurred ( 840 -No), interference unit  210  again waits to detect a signal at  820 . If the state changes to inactive ( 840 -Yes), interference unit  210  waits until the state is changed back to active ( 850 -Yes) before again awaiting to detect a signal at  820 . 
       FIG. 9  is a flowchart  900  of an example method of operating an interference unit (e.g., interference unit  210 ). For ease of description, the flowchart  900  will be discussed with reference to interference unit  210 , but this is merely an example, and one of ordinary skill will recognize, in light of the present disclosure, that the method may be performed by various other devices and in various other environments. At  910 , interference unit  210  connects to interference controller  640 . Interference controller  640  may set an activation state of interference unit  210 . In some cases, interference controller  640  may likewise connect to a remote system (e.g., server  670 ), so that the authentication privileges may be established remotely. Next, interference unit  210  determines whether it is in an active state at  920 . If interference unit  210  is in the active state ( 920 -Yes), interference unit  210  senses a signal at  930 . Interference unit  210  may sense an authentication request from an authentication terminal  150 , an authentication response from authentication key  120 , or both an authentication terminal  150  and an authentication response from authentication key  120  depending on a circumstance. 
     In response to detecting the signal, interference unit  210  outputs an interference signal at  940 . For example, interference unit  210  may output the interference signal at a sufficient magnitude to substantially block the authentication response, thus preventing authentication terminal  150  from receiving the authentication response. In other cases, the interference signal may interfere with contradict, override, or otherwise alter portions of authentication response as it appears to be received by authentication terminal  150 . Accordingly, the combination of the interference signal and the authentication response received by the authentication terminal  150  may provide different information than the authentication response received alone, making the reception invalid. In some cases, data from interference signal may comingle with data from authentication response as it is received by authentication terminal  150 . In such cases, authentication terminal  150  may be unable to differentiate the data contained in interference signal from the data contained in authentication response, making the authentication response unintelligible. 
     After outputting the interference signal, interference unit  210  may determine whether new instructions are to be received at  950 . For example, interference unit  210  may listen (e.g., periodically, constantly, near-constantly, or sporadically) for data broadcast or sent by interference controller  640 . If the data indicates a change, interference unit  210  may query interference controller  640  for additional details. In this way, interference controller  640  may not be easily located by a malicious third-party, such as with the use of a wireless signal detector/triangulator. If no new instructions are to be received ( 950 -No), interference unit  210  again determines with it is in an active state at  920 . However, if new instructions are to be received ( 950 -Yes), interference unit  210  again connects to interference controller  640  for the updated instructions (e.g., a change in state command or a change in an activation schedule). 
     As will be understood by one of ordinary skill, one benefit according to certain aspects of the present disclosure is that interference unit  210  may be swiftly installed and/or de-installed. This installation can be accomplished after-market without substantial physical interference with authentication terminal  150 . For example, once interference unit  210  is configured to a particular authentication terminal  150  and/or authentication key  120  it only needs to be placed in relative proximity to the authentication terminal  150  to operate. Accordingly, in some cases, no hardware integration of interference unit  210  with authentication terminal  150  is required for interference unit  210  to operate. In some cases, installation could include loading configuration information into the interference unit  210  (e.g., by physical or wireless connection, such as by server  270 ), and moving the interference unit  210  proximal to the authentication terminal  150 . 
     However, this is merely an example and, in some cases, interference unit  210  could be trained to a particular authentication key  120  and/or authentication terminal  150 . For example, interference unit  210  could be instructed (e.g., by server  270 ) to identify with a authentication terminal  150  (e.g., be instructed to become in learning mode) and “listen” to an authentication request and/or response or a plurality of authentication requests and/or responses. Interference unit  210  may then, by itself, or working with the server  270 , determine configuration data for listening to the particular authentication requests and/or responses and generating a configured interference signal. In some cases, interference unit  210  could communicate with server  270  to determine configuration setting based on the authentication request and/or authentication response. For example an authentication request could include vehicle identification (e.g. Vehicle Identification Number (VIN), License plate, etc.) information which could be communication to server  270 . Server  270  may access a database to determine configuration information for the particular vehicle and send configuration instructions to interference unit  210 . 
     Meanwhile, de-installation can be accomplished by removing interference unit  210  from an area proximal to authentication terminal  150 . Since interference unit  210  may not be intimately integrated with authentication terminal  150 , the installation and de-installation processes can be significantly faster and easier than the approaches described in the related art. 
     Additionally, because interference unit  210  may only require proximity to authentication terminal, it can be hidden from a user or otherwise secured. Accordingly, interference unit  210  provides additional security built into the system. For example, even if a malevolent actor acquires wireless authentication key  120 , interference unit  210 , when configured accordingly (either by its own logic, or via message from the server  270 , or from any other device able to communicate to it) can prevent authentication despite the presence of authentication key. Additionally, by being hidden, interference unit  210  cannot be easily removed or overcome. 
     In some embodiments, interference unit  210  could be configured to communicate with an additional or alternative device to server  270 . For example, a user device (such as a mobile phone or “smart phone”) could connect with and/or exchange messages with interference unit  210  directly (through the use of short range communications such as Bluetooth, Near Field Communications, 802.15.4-based protocols and the like), or indirectly through any wireless or wired communications network, through server  270 , and/or through interference unit  210 . When a user would like to activate and/or deactivate interference unit  270 , the user could send messages and/or instructions to interference unit  210  to operate accordingly. In another example, interference unit  210  can be configured to communicate with an additional device to server  270  that provides additional or alternative means of authentication of the user. This device can include, for example, a camera, a fingerprint scanner, or any other device able to recognize and authenticate the user and provide proof of authentication to the interference unit  210  either directly (e.g., through the use of a wired connection, wireless connections such as Bluetooth, Near Field Communications, 802.15.4-based protocols, UWB communications and the like), or indirectly (e.g., through a wireless or wired communications network, through server  270 , and/or through interference unit  210 ). 
       FIG. 10  is a block diagram of an illustrative system architecture  1000 , according to an example implementation. As non-limiting examples, portions of interference unit  210 , authentication terminal  150 , authentication activator  160 , wireless authentication key  120 , server  370 ,  670 , and/or interference controller  640  may be implemented using one or more elements from the system architecture  1000 . It will be understood that the device architecture  1000  is provided for example purposes only and does not limit the scope of the various implementations of the present disclosed systems, methods, and computer-readable mediums. 
     The computing device architecture  1000  of  FIG. 10  includes a central processing unit (CPU)  1002 , where computer instructions are processed, and a display interface  1004  that acts as a communication interface and provides functions for rendering video, graphics, images, and texts on the display. In certain example implementations of the disclosed technology, the display interface  1004  may be directly connected to a local display, such as a touch-screen display associated with a mobile computing device. In another example implementation, the display interface  1004  may be configured for providing data, images, and other information for an external/remote display  1050  that is not necessarily physically connected to the mobile computing device. For example, a desktop monitor may be used for mirroring graphics and other information that is presented on a mobile computing device. In certain example implementations, the display interface  1004  may wirelessly communicate, for example, via a Wi-Fi channel or other available network connection interface  1012  to the external/remote display  1050 . 
     In an example implementation, the network connection interface  1012  may be configured as a communication interface and may provide functions for rendering video, graphics, images, text, other information, or any combination thereof on the display.

In another example, the display interface  1004  may be configured to provide video, graphics, images, text, other information, or any combination thereof for an external/remote display  1050  that is not necessarily connected to the mobile computing device. In one example, a desktop monitor may be used for mirroring or extending graphical information that may be presented on a mobile device. In another example, the display interface  1004  may wirelessly communicate, for example, via the network connection interface  1012  such as a Wi-Fi transceiver to the external/remote display  1050 . 
     The computing device architecture  1000  may include a keyboard interface  1006  that provides a communication interface to a keyboard. In one example implementation, the computing device architecture  1000  may include a presence-sensitive display interface  1008  for connecting to a presence-sensitive display  1007 . According to certain example implementations of the disclosed technology, the presence-sensitive display interface  1008  may provide a communication interface to various devices such as a pointing device, a touch screen, a depth camera, etc. which may or may not be associated with a display. 
     The computing device architecture  1000  may be configured to use an input device via one or more of input/output interfaces (for example, the keyboard interface  1006 , the display interface  1004 , the presence sensitive display interface  1008 , network connection interface  1012 , camera interface  1014 , sound interface  1016 , etc.) to allow a user to capture information into the computing device architecture  1000 . The input device may include a mouse, a trackball, a directional pad, a track pad, a touch-verified track pad, a presence-sensitive track pad, a presence-sensitive display, a scroll wheel, a digital camera, a digital video camera, a web camera, a microphone, a sensor, a smartcard, and the like. Additionally, the input device may be integrated with the computing device architecture  1000  or may be a separate device. For example, the input device may be an accelerometer, a magnetometer, a digital camera, a microphone, and an optical sensor. 
     Example implementations of the computing device architecture  1000  may include an antenna interface  1010  that provides a communication interface to an antenna; a network connection interface  1012  that provides a communication interface to a network. As mentioned above, the display interface  1004  may be in communication with the network connection interface  1012 , for example, to provide information for display on a remote display that is not directly connected or attached to the system. In certain implementations, a camera interface  1014  is provided that acts as a communication interface and provides functions for capturing digital images from a camera. In certain implementations, a sound interface  1016  is provided as a communication interface for converting sound into electrical signals using a microphone and for converting electrical signals into sound using a speaker. According to example implementations, a random-access memory (RAM)  1018  is provided, where computer instructions and data may be stored in a volatile memory device for processing by the CPU  1002 . 
     According to an example implementation, the computing device architecture  1000  includes a read-only memory (ROM)  1020  where invariant low-level system code or data for basic system functions such as basic input and output (I/O), startup, or reception of keystrokes from a keyboard are stored in a non-volatile memory device. According to an example implementation, the computing device architecture  1000  includes a storage medium  1022  or other suitable type of memory (e.g. such as RAM, ROM, programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), magnetic disks, optical disks, floppy disks, hard disks, removable cartridges, flash drives), where the files include an operating system  1024 , application programs  1026  (including, for example, a web browser application, a widget or gadget engine, and or other applications, as necessary) and data files  1028  are stored. According to an example implementation, the computing device architecture  1000  includes a power source  1030  that provides an appropriate alternating current (AC) or direct current (DC) to power components. 
     According to an example implementation, the computing device architecture  1000  includes a telephony subsystem  1032  that allows the device  1000  to transmit and receive sound over a telephone network. The constituent devices and the CPU  1002  communicate with each other over a bus  1034 . 
     According to an example implementation, the CPU  1002  has appropriate structure to be a computer processor. In one arrangement, the CPU  1002  may include more than one processing unit. The RAM  1018  interfaces with the computer bus  1034  to provide quick RAM storage to the CPU  1002  during the execution of software programs such as the operating system application programs, and device drivers. More specifically, the CPU  1002  loads computer-executable process steps from the storage medium  1022  or other media into a field of the RAM  1018  to execute software programs. Data may be stored in the RAM  1018 , where the data may be accessed by the computer CPU  1002  during execution. 
     The storage medium  1022  itself may include a number of physical drive units, such as a redundant array of independent disks (RAID), a floppy disk drive, a flash memory, a USB flash drive, an external hard disk drive, thumb drive, pen drive, key drive, a High-Density Digital Versatile Disc (HD-DVD) optical disc drive, an internal hard disk drive, a Blu-Ray optical disc drive, or a Holographic Digital Data Storage (HDDS) optical disc drive, an external mini-dual in-line memory module (DIMM) synchronous dynamic random access memory (SDRAM), or an external micro-DIMM SDRAM. Such computer readable storage media allow a computing device to access computer-executable process steps, application programs and the like, stored on removable and non-removable memory media, to off-load data from the device or to upload data onto the device. A computer program product, such as one utilizing a communication system may be tangibly embodied in storage medium  1022 , which may include a machine-readable storage medium. 
     According to one example implementation, the term computing device, as used herein, may be a CPU, or conceptualized as a CPU (for example, the CPU  1002  of  FIG. 10 ). In this example implementation, the computing device (CPU) may be coupled, connected, and/or in communication with one or more peripheral devices, such as display. In another example implementation, the term computing device, as used herein, may refer to a mobile computing device such as a Smartphone, tablet computer, or smart watch. In this example implementation, the computing device may output content to its local display and/or speaker(s). In another example implementation, the computing device may output content to an external display device (e.g., over Wi-Fi) such as a TV or an external computing system. 
     In example implementations of the disclosed technology, a computing device may include any number of hardware and/or software applications that are executed to facilitate any of the operations. In example implementations, one or more I/O interfaces may facilitate communication between the computing device and one or more input/output devices. For example, a universal serial bus port, a serial port, a disk drive, a CD-ROM drive, and/or one or more user interface devices, such as a display, keyboard, keypad, mouse, control panel, touch screen display, microphone, etc., may facilitate user interaction with the computing device. The one or more I/O interfaces may be used to receive or collect data and/or user instructions from a wide variety of input devices. Received data may be processed by one or more computer processors as desired in various implementations of the disclosed technology and/or stored in one or more memory devices.
