## Title
Systems and methods for tracking paired computing devices

## Abstract

A computer-implemented method may include determining that a plurality of computing devices comprising first and second computing devices are paired via a wireless communication technology that facilitates communication between the computing devices. The computer-implemented method may also include establishing a maximum distance that the first and second computing devices are allowed to move away from one another. The computer-implemented method may further include calculating a current distance between the first and second computing devices and then determining that the current distance exceeds the maximum distance. In addition, the computer-implemented method may include providing a notification to at least one of the first and second computing devices to alert a user of the first computing device that the current distance between the first and second computing devices exceeds the maximum distance and to indicate a location of the second computing device. Various other methods, systems, and computer-readable media are also disclosed.

## Background
BACKGROUND
Computing devices have become a ubiquitous part of everyday life. In particular, millions of people may carry and use mobile computing devices (e.g., cellular telephones, MP3 players, laptops, Bluetooth headsets, etc.) throughout their daily activities. However, such computing devices (especially relatively small, mobile computing devices) may be easily misplaced by users and/or stolen by thieves.
Unfortunately, while traditional security mechanisms may enable a user to identify the location of a misplaced or stolen computing device after the fact, such traditional security mechanisms generally fail to alert the user at the point in time that the computing device is misplaced or stolen. As a result, the user may be unable to prevent the computing device from being misplaced or stolen in the first place. What is needed, therefore, is a mechanism for more effectively tracking computing devices and alerting users when computing devices are misplaced or stolen.
SUMMARY
As will be described in greater detail below, the instant disclosure generally relates to systems and methods for tracking paired computing devices. In one embodiment, a method for tracking paired computing devices may include determining that a plurality of computing devices are paired via a wireless communication technology (such as a Bluetooth technology, a Wi-Fi network, or a cellular network) that facilitates communication between the computing devices. For example, a determination module may determine that two cellular phones are paired via a Bluetooth technology. Examples of such paired computing devices include, without limitation, multiple cellular phones, a cellular phone and a Bluetooth headset, multiple cellular phones and a server, or any other suitable combination of paired computing devices.
A distance module may establish a maximum distance that the paired computing devices are allowed to move away from one another. In one example, the distance module may enable a user of one of the paired computing devices to specify the maximum distance via a user interface. In another example, the distance module may obtain a predetermined maximum distance from security software installed on the paired computing devices.
The distance module may also calculate a current distance between the paired computing devices. In one example, a paired computing device may send a communication to another paired computing device. In this example, the distance module may then determine the amount of time required to send the communication between the paired computing devices and then use this amount of time to calculate the current distance between the paired computing devices.
In another example, the distance module may obtain coordinates that identify a geographic location of each of the paired computing devices. For example, the distance module may obtain GPS coordinates that identify the geographic locations of two paired cellular phones from GPS devices located on the paired cellular phones. In this example, the distance module may use the coordinates to calculate the current distance between the paired computing devices.
The distance module may then determine that the current distance between the paired computing devices exceeds the maximum distance that the paired computing devices are allowed to move away from one another. For example, the distance module may compare the current distance with the maximum distance to determine that the current distance is greater than the maximum distance. After the current distance has been determined to exceed the maximum distance, a notification module may provide a notification to at least one of the paired computing devices to alert a user of the paired computing device that the current distance exceeds the maximum distance. The notification module may also notify the user of the location of at least one other paired computing device (e.g., the misplaced or stolen computing device). By alerting the user of the paired computing device that the current distance exceeds the maximum distance, and by providing the user with location information about a paired computing device, the notification may prompt the user to immediately find the paired computing device that is not in the user's possession to prevent such a paired computing device from being lost or stolen.
In some examples, the notification module may initiate a phone call and/or send a text message to at least one paired computing device (such as a paired cellular phone). In one example, the notification module may obtain coordinates that identify a geographic location of a paired cellular phone that has moved beyond the maximum distance. In this example, the notification module may then provide the geographic location of this paired cellular phone in a text message to enable another paired cellular phone to present the geographic location to a user in a geographic map. In other examples, the notification module may cause at least one paired computing device (such as a paired cellular phone or Bluetooth headset) to vibrate, emit at least one noise, and/or flash at least one light.
In further examples, the current distance between a paired server and a paired cellular phone may prevent the paired server from directly communicating with the paired cellular phone. In such examples, the notification module may send a notification from the paired server to another paired cellular phone to relay the notification to the paired cellular phone with which the server is unable to directly communicate.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
As will be described in greater detail below, the instant disclosure generally relates to systems and methods for tracking paired computing devices. For example, two cellular phones may pair via a Bluetooth technology to enable security software to monitor the distance between the paired cellular phones. If the distance between the paired cellular phones ever exceeds the maximum distance allowed by the security software (e.g., if a user inadvertently leaves a paired cellular phone at a particular location but walks away with another paired cellular phone), the security software may provide a notification to at least one of the paired cellular phones to alert a user that the distance between the paired cellular phones exceeds the maximum distance allowed by the security software and to provide device-location information to the user. By alerting the user that the distance between the paired cellular phones exceeds the maximum distance, and by providing device-location information to the user, the notification provided by the security software may prompt the user to immediately find the paired cellular phone that is not in the user's possession to prevent this paired cellular phone from being lost or stolen.
The following will provide, with reference to FIGS. 1-2, detailed descriptions of exemplary systems for tracking paired computing devices. Detailed descriptions of corresponding computer-implemented methods will also be provided in connection with FIG. 3-5. In addition, detailed descriptions of an exemplary computing system and network architecture capable of implementing one or more of the embodiments described herein will be provided in connection with FIGS. 6 and 7, respectively.
FIG. 1 is a block diagram of an exemplary system 100 for tracking paired computing devices. As illustrated in this figure, exemplary system 100 may include one or more modules 102 for performing one or more tasks. For example, and as will be explained in greater detail below, exemplary system 100 may include a determination module 104 programmed to determine that a plurality of computing devices are paired via a wireless communication technology that facilitates communication between the computing devices.
Exemplary system 100 may also include a distance module 106 programmed to establish a maximum distance that the paired computing devices are allowed to move away from one another. Distance module 106 may be further programmed to calculate a current distance between the paired computing devices and then determine that the current distance between the paired computing devices exceeds the maximum distance. In addition, and as will be described in greater detail below, exemplary system 100 may include a notification module 108 programmed to provide a notification to at least one of the paired computing devices to alert a user of the paired computing device that the current distance between the paired computing devices exceeds the maximum distance and to provide the user with device-location information. Although illustrated as separate elements, one or more of modules 102 in FIG. 1 may represent portions of a single module or application (such as security software installed on paired computing devices or an application that provides one or more built-in functions of paired computing devices).
In certain embodiments, one or more of modules 102 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing device, may cause the computing device to perform one or more tasks. For example, as will be described in greater detail below, one or more of modules 102 may represent software modules stored and configured to run on one or more computing devices, such as paired computing devices 202(1)-(2) in FIG. 2, server 502 in FIG. 5, cellular phones 508(1)-(2) in FIG. 5, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7. One or more of modules 102 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks.
As illustrated in FIG. 1, exemplary system 100 may also include one or more databases 120. Databases 120 may represent portions of a single database or computing device or a plurality of databases or computing devices. In one embodiment, exemplary system 100 may include a pairing-information database 122 configured to store information used to pair and/or identify a plurality of paired computing devices. Examples of such information include, without limitation, identification addresses (such as IP addresses or MAC addresses), registration keys, link keys, or any other information related to paired computing devices.
In addition, exemplary system 100 may include a notification-information database 124 configured to store information that identifies one or more types of notifications to be provided to paired computing devices. Examples of such information include, without limitation, location information for paired computing devices, information that directs notification module 108 to initiate a phone call to at least one paired computing device, send a text message to at least one paired computing device, cause at least one paired computing device to vibrate, cause at one paired computing device to vibrate or emit at least one noise or flash at least one light, or any other information related to notifications provided to paired computing devices.
Databases 120 in FIG. 1 may represent a portion of one or more computing devices. For example, databases 120 may represent a portion of one or more of paired computing devices 202(1)-(2) in FIG. 2, server 502 in FIG. 5, one or more of cellular phones 508(1)-(2) in FIG. 5, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7. Alternatively, databases 120 in FIG. 1 may represent one or more physically separate devices capable of being accessed by a computing device, such as one of paired computing devices 202(1)-(2) in FIG. 2, server 502 in FIG. 5, one of cellular phones 508(1)-(2) in FIG. 5, computing system 610 in FIG. 6, and/or portions of exemplary network architecture 700 in FIG. 7.
Exemplary system 100 in FIG. 1 may be deployed in a variety of ways. For example, all or a portion of exemplary system 100 may represent portions of exemplary system 200 in FIG. 2. As shown in FIG. 2, exemplary system 200 may include computing device 202(1)-(2) capable of pairing and communicating with one another via a wireless communication technology (such as a Bluetooth technology, a Wi-Fi network, or a cellular network). In one embodiment, and as will be described in greater detail below, paired computing devices 202(1)-(2) may be programmed by determination module 104 to pair via a wireless communication technology.
In some embodiments, paired computing devices 202(1)-(2) may be programmed by distance module 106 to establish a maximum distance that the paired computing devices are allowed to move away from one another. Paired computing devices 202(1)-(2) may also be programmed by distance module 106 to calculate a current distance between paired computing devices 202(1)-(2) and then determine that the current distance exceeds the maximum distance that paired computing devices 202(1)-(2) are allowed to move away from one another. In addition, paired computing devices 202(1)-(2) may be programmed by notification module 108 to provide a notification to at least one of paired computing devices 202(1)-(2) to alert a user of the paired computing device that the current distance between paired computing devices 202(1)-(2) exceeds the maximum distance.
Each of paired computing devices 202(1)-(2) generally represents any type or form of computing device capable of reading computer-executable instructions and pairing with another computing device via a wireless communication technology. Examples of paired computing devices 202(1)-(2) include, without limitation, cellular phones, Bluetooth headsets, laptop computers, tablet computers, MP3 players, Global Positioning System (GPS) devices, combinations of one or more of the same, and/or any other suitable computing devices.
In some embodiments, paired computing devices 202(1)-(2) may be paired via a wireless communication technology that facilitates communication between paired computing devices 202(1)-(2). Examples of such a wireless communication technology include, without limitation, a Bluetooth technology (such as a device that facilitates communication using the Bluetooth technology standard), a Wi-Fi network (such as a wireless local area network (WLAN) or a wireless personal area network (WPAN)), a cellular network (such as a GSM network or a CDMA network), or any other suitable wireless communication technology.
FIG. 3 is a flow diagram of an exemplary computer-implemented method 300 for tracking paired computing devices. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1 and/or system 200 in FIG. 2.
As illustrated at step 302 in FIG. 3, the various systems described herein may determine that a plurality of computing devices are paired via a wireless communication technology that facilitates communication between the computing devices. For example, determination module 104 may, as part of one or more of computing devices 202(1)-(2), determine that computing devices 202(1)-(2) are paired via a wireless communication technology. In this example, the wireless communication technology may be a Bluetooth technology, a Wi-Fi network, a cellular network, or any other suitable wireless communication technology.
The term “paired” (or “pairing”), as used herein, generally refers to any type or form of secure connection that has been established between a plurality of computing devices. Such a secure connection may enable paired computing devices 202(1)-(2) to exchange encrypted communications and prevent other non-paired computing devices from interpreting encrypted communications exchanged between paired computing devices 202(1)-(2).
The systems described herein may perform step 302 in a variety of ways. In one example, determination module 104 may identify a link key that enables computing devices 202(1)-(2) to cryptographically authenticate communications received from one another. For example, determination module 104 may locate a link key within pairing-information database 122 stored on at least one of computing devices 202(1)-(2). In another example, determination module 104 may determine that a plurality of computing devices are paired via a wireless communication technology by identifying at least one encrypted communication sent between computing devices 202(1)-(2).
In some embodiments, the link key may be used to generate an encryption/decryption key that enables paired computing devices 202(1)-(2) to encrypt and/or decrypt communications from one another. In other embodiments, the link key itself may serve as an encryption/decryption key that enables paired computing devices 202(1)-(2) to encrypt and/or decrypt communications from one another.
In a further example, determination module 104 may determine that a plurality of computing devices are paired via a wireless communication technology by identifying at least one device identifier (such as an IP address, a MAC address, or a phone number) within pairing-information database 122. For example, determination module 104 may locate a device identifier that identifies paired computing device 202(1) within pairing-information database 122 stored on paired computing device 202(2). In this example, the device identifier may identify paired computing device 202(1) as a computing device that is paired with computing device 202(2) via a wireless network (such as a Wi-Fi network or cellular network).
In other embodiments, determination module 104 may determine that a plurality of computing devices are paired by querying one or more of the paired devices. For example, determination module 104 may query an operating system, Bluetooth service, wireless service, and/or any other suitable system on a device to determine whether the device is paired with another device.
As illustrated at step 304 in FIG. 3, the various systems described herein may establish a maximum distance that the paired computing devices are allowed to move away from one another. For example, distance module 106 may, as part of one or more of paired computing devices 202(1)-(2), establish a maximum distance 204 that paired computing devices 202(1)-(2) are allowed to move away from one another. In this example, maximum distance 204 may represent any distance within which the wireless communication technology is capable of facilitating communication between paired computing devices 202(1)-(2). In other examples, the maximum distance may be established as the maximum range of wireless communications between the paired devices.
The systems described herein may perform step 304 in a variety of ways. In one example, distance module 106 may establish maximum distance 204 by obtaining a predetermined maximum distance from security software installed on paired computing devices 202(1)-(2). For example, the predetermined maximum distance may be stored as a default setting within the security software installed on paired computing devices 202(1)-(2).
In another example, distance module 106 may enable a user of paired computing device 202(1) to specify maximum distance 204. For example, distance module 106 may cause paired computing device 202(1) to display a user interface that enables a user of paired computing device 202(1) to enter maximum distance 204. In this example, the user interface may prompt the user to enter maximum distance 204 or simply allow the user to change maximum distance 204 (from, e.g., a predetermined maximum distance) without being prompted.
As illustrated at step 306 in FIG. 3, the various systems described herein may calculate a current distance between the paired computing devices. For example, distance module 106 may, as part of one or more of paired computing devices 202(1)-(2), calculate a current distance 206 between paired computing devices 202(1)-(2). In this example, current distance 206 may represent a distance measured between paired computing devices 202(1)-(2) at a particular point in time. In addition, distance module 106 may be configured to calculate a new current distance at scheduled intervals.
The systems described herein may perform step 306 in a variety of ways. In one example, paired computing device 202(1) may send a communication to paired computing device 202(2) and determine the amount of time required to send the communication from paired computing device 202(1) to paired computing device 202(2). In this example, distance module 106 may then use the amount of time required to send the communication from paired computing device 202(1) to paired computing device 202(2) to calculate current distance 206 between paired computing devices 202(1)-(2). For example, distance module 106 may calculate current distance 206 by multiplying the amount of time required to send the communication by the known speed (e.g., the speed of light divided by the refractive index of air) at which the communication travelled from paired computing device 202(1) to paired computing device 202(2).
In another example, distance module 106 may obtain coordinates that identify a geographic location of each of paired computing devices 202(1)-(2). For example, distance module 106 may obtain a set of GPS coordinates that identify the geographic location of paired computing device 202(1) from a GPS device located on paired computing device 202(1). Similarly, distance module 106 may obtain another set of GPS coordinates that identify the geographic location of paired computing device 202(2) from another GPS device located on paired computing device 202(2). In this example, distance module 106 may cause computing device 202(1) to send the set of GPS coordinates that identify the geographic location of paired computing device 202(1) to paired computing device 202(2).
After computing device 202(2) has received the set of GPS coordinates that identify the geographic location of paired computing device 202(1), distance module 106 may use both sets of GPS coordinates to calculate current distance 206 between paired computing devices 202(1)-(2). For example, distance module 106 may identify the respective latitude and longitude coordinates of paired computing devices 202(1)-(2) within the sets of GPS coordinates. In this example, distance module 106 may then calculate the current distance between paired computing devices 202(1)-(2) by applying the latitude and longitude coordinates (formatted in radians) to a Haversine formula based on the Earth's radius.
In some embodiments, distance module 106 may calculate a current distance between the first and second computing devices by determining that the first and second computing devices are not within range of one another. For example, distance module 106 may determine that the first and second computing devices are no longer within a wireless range of each other (e.g., by determining that the devices are no longer paired and/or that the devices are unable to pair). In such embodiments, the maximum distance is established by the range of the wireless mechanism used to pair the devices.
As illustrated at step 308 in FIG. 3, distance module 106 may determine that the current distance between the paired computing devices exceeds the maximum distance that the paired computing devices are allowed to move away from one another. For example, distance module 106 may, as part of one or more of paired computing devices 202(1)-(2), determine that current distance 206 exceeds maximum distance 204.
The systems described herein may perform step 308 in a variety of ways. In one example, distance module 106 may determine that current distance 206 exceeds maximum distance 204 by comparing current distance 206 with maximum distance 204. For example, distance module 106 may compare current distance 206 with maximum distance 204 and determine that current distance 206 is greater than maximum distance 204.
In embodiments where calculating the current distance between paired computing devices comprises determining that the paired computing devices are no longer within wireless range of each other, determining that the current distance between the first and second computing devices exceeds the maximum range may include checking a policy (e.g., a policy set by establishing the maximum distance in step 304) to determine whether the devices are allowed out of wireless range of one another. If the policy indicates that the devices are not allowed to be out of wireless range of one another, distance module 106 may conclude that the maximum distance has been exceeded. In such embodiments, the paired devices may not be able to communication with each other, and any notifications sent between the paired devices may be transmitted through an intermediate network (e.g., the Internet, a WAN, a LAN, etc.) and/or through an intermediate paired device that is still within range of each of the other paired devices.
As illustrated at step 310 in FIG. 3, distance module 106 may provide a notification to at least one of the paired computing devices to alert a user of the paired computing device that the current distance between the paired computing devices exceeds the maximum distance. For example, notification module 108 may, as part of one or more of paired computing devices 202(1)-(2), provide a notification to at least one of paired computing devices 202(1)-(2) to alert a user of the paired computing device that current distance 206 exceeds maximum distance 204. In this example, notification module 108 may determine the type of notification (e.g., phone call, text message, vibration, flashing light, and/or noise) to provide to the paired computing device by locating information that identifies the type of notification within notification-information database 124.
The systems described herein may perform step 310 in a variety of ways. In one example, notification module 108 may initiate a phone call to paired computing device 202(1) and/or paired computing device 202(2). For example, if paired computing devices 202(1)-(2) represent two paired cellular phones, notification module 108 may initiate a phone call from one paired cellular phone to another paired cellular phone. In this example, the phone call may alert a user of the other paired cellular phone that current distance 206 exceeds maximum distance 204. For example, the phone call may play a prerecorded sound clip that verbally informs the user that current distance 206 exceeds maximum distance 204.
In another example, notification module 108 may cause at least one of paired computing devices 202(1)-(2) to vibrate. For example, if paired computing devices 202(1)-(2) represent two paired cellular phones, notification module 108 may cause at least one of the paired cellular phones to vibrate. Similarly, if paired computing devices 202(1)-(2) represent a cellular phone and a Bluetooth headset, notification module 108 may cause at least one of the cellular phone and the Bluetooth headset to vibrate. In this example, by causing at least one of paired computing devices 202(1)-(2) to vibrate, notification module 108 may alert a user of the paired computing device that current distance 206 exceeds maximum distance 204.
In a further example, notification module 108 may cause at least one of paired computing devices 202(1)-(2) to emit a noise. For example, if paired computing devices 202(1)-(2) represent two paired cellular phones, notification module 108 may cause at least one of the paired cellular phones to emit a noise (such as a chime) that indicates current distance 206 exceeds maximum distance 204. Similarly, if paired computing devices 202(1)-(2) represent a cellular phone and a Bluetooth headset (respectively), notification module 108 may cause at least one of the cellular phone and the Bluetooth headset to emit a noise (such as a chime) that indicates current distance 206 exceeds maximum distance 204. In this example, by causing at least one of paired computing devices 202(1)-(2) to emit a noise, notification module 108 may alert a user of the paired computing device that current distance 206 exceeds maximum distance 204.
In an additional example, notification module 108 may cause at least one of paired computing devices 202(1)-(2) to flash at least one light. For example, if paired computing devices 202(1)-(2) represent two paired cellular phones, notification module 108 may cause at least one of the paired cellular phones to flash at least one light that indicates current distance 206 exceeds maximum distance 204. Similarly, if paired computing devices 202(1)-(2) represent a cellular phone and a Bluetooth headset (respectively), notification module 108 may cause at least one of the cellular phone and the Bluetooth headset to flash at least one light that indicates current distance 206 exceeds maximum distance 204. In this example, by causing at least one of paired computing devices 202(1)-(2) to flash at least one light, notification module 108 may alert a user of the paired computing device that current distance 206 exceeds maximum distance 204.
In some examples, notification module 108 may send a text message, voice message, email, instant message, or other electronic message to paired computing device 202(1) and/or paired computing device 202(2). For example, if paired computing devices 202(1)-(2) represent two paired cellular phones, notification module 108 may send a text message from one paired cellular phone to another paired cellular phone. In this example, the text message may alert a user of the other paired cellular phone that current distance 206 exceeds maximum distance 204.
In one example, notification module 108 may provide location information that indicates the location of one or more of the paired devices. For example, notification module 108 may provide coordinates that identify the geographic location of the paired cellular phone in the text message sent to the other paired cellular phone. In one embodiment, notification module 108 may obtain GPS coordinates that identify the geographic location of the paired cellular phone from a GPS device. In this example, notification module 108 may then include the GPS coordinates that identify the geographic location of the cellular phone in a text message, email message, instant message, voice message, and/or other message sent to the other paired cellular phone. This message may enable the other paired cellular phone to present the geographic location of the misplaced or stolen paired cellular phone to a user in a geographic map.
Notification module 108 may also provide location information in a variety of other ways. For example, notification module 108 may use cellular-phone triangulation data to identify a location of a paired device (e.g., a lost or stolen device) and may send this location information to another paired device (e.g., a device that is still with a user).
In some embodiments, notification module 108 may send a notification that causes a misplaced or stolen device to be locked or otherwise disabled to protect confidential information. For example, notification module 108 may send a notification to a cellular telephone or laptop that causes the phone or laptop to lock itself against unauthorized access.
As illustrated in FIG. 4, exemplary text message 400 may be sent from paired cellular phone 402(2) to paired cellular phone 402(1). In one example, exemplary text message 400 may include coordinates that identify the geographic location of paired cellular phone 402(2). In this example, upon identifying the coordinates within exemplary text message 400, paired cellular phone 402(1) may use the coordinates to present the geographic location of paired cellular phone 402(2) relative to the geographic location of paired cellular phone 402(1) in a geographic map 404.
In some embodiments, geographic map 404 may include one or more physical structures and/or landmarks to provide identifying context to the geographic location of paired cellular phone 402(1) and/or paired cellular phone 402(2). For example, geographic map 404 may include one or more streets (e.g., “State St.,” “Main St.,” “Union St.,” and “Confederate St.”) that surround the geographic location of paired cellular phone 402(1) and/or paired cellular phone 402(2). In addition, geographic map 404 may be presented to a user in a variety of designs, styles, shapes, colors, and/or sizes.
In some embodiments, notification module 108 may send one or more notifications to each of the paired computing devices. In other embodiments, notification module 108 may send one or more notification to only one of the paired devices or to any other subset of the paired devices. In such embodiments, notification module 108 and/or distance module 106 may attempt to determine which of the paired devices is lost or misplaced so that a notification may be send to one or more other paired devices that are still in the user's possession. For example, distance module 108 may determine (e.g., using GPS, an accelerometer, or any other suitable technology) that one of the paired devices is moving and the other paired device is not moving. In such embodiments, distance module 104 may assume that the moving device is the device that is still with the user and may send the notification only to the moving paired device.
In other embodiments, distance module 104 may assume that a stationary device is with the user (e.g., if the moving device is stolen) and may send the notification to only the stationary paired device. A user may be able to select which mode (i.e., send notifications only to stationary devices, send notifications only to the moving device, send notifications to all devices, send notifications to a subset of devices, etc.) notification module 108 uses for providing notifications.
As illustrated in FIG. 5, exemplary system 500 may include server 502 and laptops 508(1)-(2) capable of pairing and communicating with one another via a wireless communication technology (such as a Bluetooth technology, a Wi-Fi network, or a cellular network). For example, each of laptops 508(1)-(2) may be paired with server 502 via a Wi-Fi network. In another example, server 502 and laptops 508(1)-(2) may all be paired with one another via a Wi-Fi network.

Current distances 506(1)-(2) may be calculated in a variety of ways, including any of those described above in connection with current distance 206.
In one example, distance module 106 may determine that current distance 506(1) is preventing server 502 from being able to directly communicate with laptop 508(1). For example, server 502 may be unable to directly communicate with laptop 508(1) because laptop 508(1) is out of range (meaning that the wireless communication technology is unable to facilitate communication at current distance 506(1)). In this example, notification module 108 may send the notification from server 502 to laptop 508(2). Upon receiving the notification, laptop 508(2) may then relay the notification to laptop 508(1) with which server 502 is unable to directly communicate. In some embodiments, such a notification may notify a user of laptop 508(1) that the laptop is out of an approved area and should be returned to the approved area. In certain embodiments, the notification may disable laptop 508(1) (e.g., by shutting down laptop 508(1), locking laptop 508(1), etc.) to unauthorized access of data on laptop 508(1).
