The electronic device acquires location information for the tracking report through a location awareness capability such as a global positioning system. The electronic device acquires user identification information for the tracking report through a biometric scanning component, such as a finger print sensor or other device that senses biometric properties when a user is touching or in close proximity to the device.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation-in-part of U.S. patent application Ser. No. 13/841,020, which was filed on Mar. 15, 2013, and entitled “Biometric Receipt,” which application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/666,722, which was filed on Jun. 29, 2012, and entitled “Biometric Receipt,” both of which are incorporated by reference as if fully disclosed herein.


TECHNICAL FIELD
The present invention relates generally to electronic devices, and more specifically to tracking mechanisms for electronic devices.
BACKGROUND
Electronic devices, such as mobile or cellular phones, may be equipped with location awareness capabilities that allow the electronic device to track its own location. For example, the electronic device may includes a global positioning system (GPS) that communicates with a number of orbiting satellites to determine the present location of the electronic device. By using the location awareness capabilities of an electronic device, an individual or group may track the location of the user of the electronic device by using the location of electronic device as a proxy for the location of the user of electronic device. For example, a parent who wishes to track the location of a child may give the child a mobile phones that has location awareness capabilities. By tracking the location of the mobile phone, the parent is able to track the location of the child.
However, the effectiveness of using the location of an electronic device as a proxy for the user of the electronic device is limited by the uncertainty of not knowing whether or not the user is actually carrying the electronic device at a particular time. For example, a child may leave his electronic device in a locker when he leaves school at the end of the day. Because the child is separated from the electronic device, tracking the location child by tracking the location of the electronic device becomes less effective.
SUMMARY
Examples of embodiments described herein may take the form of an electronic device such as a mobile telephone that provides a tracking report to a computing device that is located remotely from the electronic device. The tracking report may include location information that identifies the geographical location of the electronic device, and device user information that identifies the user of the electronic device. The electronic device may acquire location information for the tracking report through a location awareness capability such as a global positioning system. The electronic device may acquire user identification information for the tracking report through a biometric scanning component, such as a finger print sensor or other device that senses biometric properties when a user is touching or in close proximity to the device.
In accordance with various example embodiments described herein, a electronic device may report tracking information periodically or in response to a specific request. When the electronic device compiles data to include in the tracking report, the electronic device may use stored biometric information that was acquired in a recent biometric scan. Alternatively, compiling data to include in the tracking report may include initiating a fresh biometric. A biometric scan that is initiated to acquire information for a tracking report may done discreetly, without the user knowing that the scan is taking place. Alternatively, the user may be alerted that a scan is required and promoted to enter biometric information.

SPECIFICATION
This disclosure relates generally to location tracking using a location aware electronic device that includes a biometric scanning capability. In accordance with embodiments discussed herein, an electronic device may report tracking information that includes the current location of the electronic device in combination with information identifying the user of the electronic device. The electronic device may acquire location information for the tracking report through a location awareness capability such as a global positioning system. The electronic device may acquire user identification information for the tracking report through a biometric scanning component, such as a finger print sensor or other device that senses biometric properties when a user is touching or in close proximity to the device.
By combining location awareness with a biometric scan, an individual or group may more effectively track the location of the user of the electronic device. Because the tracking report identifies the user of electronic device and because the biometric information used to identify the user was input when the user and the electronic were at least in close proximity, the location of the electronic device can be used as a reasonable proxy for the location of the user. For example, a parent who wishes to track the location of child may do so by employing embodiments discussed herein to track the location of the child's mobile phone. Because the tracking report includes information identifying the user of the mobile phone, the parent can know whether or not the child is separated from the phone. It should be noted that parental tracking is discussed herein by way of example and not limitation, and that embodiments discussed herein may be used in other contexts. For example, embodiments discussed herein may be used by courts to track compliance with restraining orders or house arrest boundaries. In another example, governments may track compliance diplomatic geographic restrictions.
The electronic device may report the tracking information periodically or in response to a specific request. When the electronic device compiles data to include in the tracking report, the electronic device may use stored biometric information that was acquired in a recent biometric scan. Alternatively, compiling data to include in the tracking report may include initiating a fresh biometric scan so that the tracking report correctly identifies the current user of the electronic device. A biometric scan that is initiated to acquire information for a tracking report may done discreetly, without the user knowing that the scan is taking place. Alternatively, the user may be alerted that a scan is required and promoted to enter biometric information.
Embodiments described herein may be configured to operate with a variety of sensors, including strip or swipe sensors, array or other two-dimensional sensors, and the like. FIG. 1 is a schematic illustration of an electronic device 1000 in accordance with embodiments discussed herein. As shown in FIG. 1, an electronic device 1000 embodiment may include touch I/O device 1001 that can receive touch input for interacting with computing system 1003 via wired or wireless communication channel 1002. Touch I/O device 1001 may be used to provide user input to computing system 1003 in lieu of or in combination with other input devices such as a keyboard, mouse, etc. One or more touch I/O devices 1001 may be used for providing user input to computing system 1003. Touch I/O device 1001 may be an integral part of computing system 1003 (e.g., touch screen on a laptop) or may be separate from computing system 1003. In one embodiment, biometric scanning is provided by a fingerprint sensor capability of the electronic device. Here, the computing system 1003 may be operable to acquire a fingerprint from a finger that is used to enter inputs through the touch I/O device 1001.
Touch I/O device 1001 may include a touch sensitive panel which is wholly or partially transparent, semitransparent, non-transparent, opaque or any combination thereof. Touch I/O device 1001 may be embodied as a touch screen, touch pad, a touch screen functioning as a touch pad (e.g., a touch screen replacing the touchpad of a laptop), a touch screen or touchpad combined or incorporated with any other input device (e.g., a touch screen or touchpad disposed on a keyboard) or any multi-dimensional object having a touch sensitive surface for receiving touch input.
In one example, touch I/O device 1001 embodied as a touch screen may include a transparent and/or semitransparent touch sensitive panel partially or wholly positioned over at least a portion of a display. According to this embodiment, touch I/O device 1001 functions to display graphical data transmitted from computing system 1003 (and/or another source) and also functions to receive user input. In other embodiments, touch I/O device 1001 may be embodied as an integrated touch screen where touch sensitive components/devices are integral with display components/devices. In still other embodiments a touch screen may be used as a supplemental or additional display screen for displaying supplemental or the same graphical data as a primary display and to receive touch input.
Touch I/O device 1001 may be configured to detect the location of one or more touches or near touches on device 1001 based on capacitive, resistive, optical, acoustic, inductive, mechanical, chemical measurements, or any phenomena that can be measured with respect to the occurrences of the one or more touches or near touches in proximity to deice 1001. Software, hardware, firmware or any combination thereof may be used to process the measurements of the detected touches to identify and track one or more gestures. A gesture may correspond to stationary or non-stationary, single or multiple, touches or near touches on touch I/O device 1001. A gesture may be performed by moving one or more fingers or other objects in a particular manner on touch I/O device 1001 such as tapping, pressing, rocking, scrubbing, twisting, changing orientation, pressing with varying pressure and the like at essentially the same time, contiguously, or consecutively. A gesture may be characterized by, but is not limited to a pinching, sliding, swiping, rotating, flexing, dragging, or tapping motion between or with any other finger or fingers. A single gesture may be performed with one or more hands, by one or more users, or any combination thereof.
Computing system 1003 may drive a display with graphical data to display a graphical user interface (GUI). The GUI may be configured to receive touch input via touch I/O device 1001. Embodied as a touch screen, touch I/O device 1001 may display the GUI. Alternatively, the GUI may be displayed on a display separate from touch I/O device 1001. The GUI may include graphical elements displayed at particular locations within the interface. Graphical elements may include but are not limited to a variety of displayed virtual input devices including virtual scroll wheels, a virtual keyboard, virtual knobs, virtual buttons, any virtual UI, and the like. A user may perform gestures at one or more particular locations on touch I/O device 1001 which may be associated with the graphical elements of the GUI. In other embodiments, the user may perform gestures at one or more locations that are independent of the locations of graphical elements of the GUI. Gestures performed on touch I/O device 1001 may directly or indirectly manipulate, control, modify, move, actuate, initiate or generally affect graphical elements such as cursors, icons, media files, lists, text, all or portions of images, or the like within the GUI. For instance, in the case of a touch screen, a user may directly interact with a graphical element by performing a gesture over the graphical element on the touch screen. Alternatively, a touch pad generally provides indirect interaction. Gestures may also affect non-displayed GUI elements (e.g., causing user interfaces to appear) or may affect other actions within computing system 1003 (e.g., affect a state or mode of a GUI, application, or operating system). Gestures may or may not be performed on touch I/O device 1001 in conjunction with a displayed cursor. For instance, in the case in which gestures are performed on a touchpad, a cursor (or pointer) may be displayed on a display screen or touch screen and the cursor may be controlled via touch input on the touchpad to interact with graphical objects on the display screen. In other embodiments in which gestures are performed directly on a touch screen, a user may interact directly with objects on the touch screen, with or without a cursor or pointer being displayed on the touch screen.
Feedback may be provided to the user via communication channel 1002 in response to or based on the touch or near touches on touch I/O device 1001. Feedback may be transmitted optically, mechanically, electrically, olfactory, acoustically, or the like or any combination thereof and in a variable or non-variable manner.
Attention is now directed towards embodiments of a system architecture that may be embodied within any portable or non-portable device including but not limited to a communication device (e.g. mobile phone, smart phone), a multi-media device (e.g., MP3 player, TV, radio), a portable or handheld computer (e.g., tablet, netbook, laptop), a desktop computer, an All-In-One desktop, a peripheral device, or any other system or device adaptable to the inclusion of system architecture 2000, including combinations of two or more of these types of devices.

The memory hierarchy can be implemented using any combination of RAM (e.g., SRAM, DRAM, DDRAM), ROM, FLASH, magnetic and/or optical storage devices, such as disk drives, magnetic tape, CDs (compact disks) and DVDs (digital video discs). Medium 2001 may also include a transmission medium for carrying information-bearing signals indicative of computer instructions or data (with or without a carrier wave upon which the signals are modulated). For example, the transmission medium may include a communications network, including but not limited to the Internet (also referred to as the World Wide Web), intranet(s), Local Area Networks (LANs), Wide Local Area Networks (WLANs), Storage Area Networks (SANs), Metropolitan Area Networks (MAN) and the like.
One or more processors 2018 run various software components stored in medium 2001 to perform various functions for system 2000. In some embodiments, the software components include operating system 2022, communication module (or set of instructions) 2024, touch processing module (or set of instructions) 2026, graphics module (or set of instructions) 2028, one or more applications (or set of instructions) 2030, and fingerprint sensing module (or set of instructions) 2038. Each of these modules and above noted applications correspond to a set of instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. In some embodiments, medium 2001 may store a subset of the modules and data structures identified above. Furthermore, medium 2001 may store additional modules and data structures not described above.

Graphics module 2028 includes various known software components for rendering, animating and displaying graphical objects on a display surface. In embodiments in which touch I/O device 2012 is a touch sensitive display (e.g., touch screen), graphics module 2028 includes components for rendering, displaying, and animating objects on the touch sensitive display.
One or more applications 2030 can include any applications installed on system 2000, including without limitation, a browser, address book, contact list, email, instant messaging, word processing, keyboard emulation, widgets, JAVA-enabled applications, encryption, digital rights management, voice recognition, voice replication, location determination capability (such as that provided by the global positioning system (GPS)), a music player, etc.
Touch processing module 2026 includes various software components for performing various tasks associated with touch I/O device 2012 including but not limited to receiving and processing touch input received from I/O device 2012 via touch I/O device controller 2032.
System 2000 may further include a fingerprint sensing module 2038 that may at least be executed to, or otherwise function to, perform various tasks associated with the fingerprint sensor, such as receiving and processing fingerprint sensor input. The fingerprint sensing module 2038 may also control certain operational aspects of the fingerprint sensor 2042, such as its capture of fingerprint data and/or transmission of the same to the processor 2018 and/or secure processor 2040. Module 2038 may also interact with the touch I/O device 2012, graphics module 2028 or other graphical display. Module 2038 may be embodied as hardware, software, firmware, or any combination thereof. Although module 2038 is shown to reside within medium 2001, all or portions of module 2038 may be embodied within other components within system 2000 or may be wholly embodied as a separate component within system 2000.
System 2000 may further include a tracking module 2039 for performing the method/functions as described herein in connection with FIGS. 3-7. The tracking module 2039 may at least function to compile tracking reports that are communicated to a remote computing system. In connection with compiling tracking reports, the tracking module 2039 may acquire biometric data for the device user. Here, the tracking module 2039 may cooperate with the fingerprint sensing module 2038 to acquire fingerprint data that can be used to identify the device user. Additionally, the tracking module 2039 may cooperate with the communication module 2024 to receive tracking requests and to send tracking reports.
I/O subsystem 2006 is coupled to touch I/O device 2012 and one or more other I/O devices 2014 for controlling or performing various functions. Touch I/O device 2012 communicates with processing system 2004 via touch I/O device controller 2032, which includes various components for processing user touch input (e.g., scanning hardware). One or more other input controllers 2034 receives/sends electrical signals from/to other I/O devices 2014. Other I/O devices 2014 may include physical buttons, dials, slider switches, sticks, keyboards, touch pads, additional display screens, or any combination thereof.
If embodied as a touch screen, touch I/O device 2012 displays visual output to the user in a GUI. The visual output may include text, graphics, video, and any combination thereof. Some or all of the visual output may correspond to user-interface objects. Touch I/O device 2012 forms a touch-sensitive surface that accepts touch input from the user. Touch I/O device 2012 and touch screen controller 2032 (along with any associated modules and/or sets of instructions in medium 2001) detects and tracks touches or near touches (and any movement or release of the touch) on touch I/O device 2012 and converts the detected touch input into interaction with graphical objects, such as one or more user-interface objects. In the case in which device 2012 is embodied as a touch screen, the user can directly interact with graphical objects that are displayed on the touch screen. Alternatively, in the case in which device 2012 is embodied as a touch device other than a touch screen (e.g., a touch pad), the user may indirectly interact with graphical objects that are displayed on a separate display screen embodied as I/O device 2014.
Touch I/O device 2012 may be analogous to the multi-touch sensitive surface described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference.
Embodiments in which touch I/O device 2012 is a touch screen, the touch screen may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, OLED (organic LED), or OEL (organic electro luminescence), although other display technologies may be used in other embodiments.
Feedback may be provided by touch I/O device 2012 based on the user's touch input as well as a state or states of what is being displayed and/or of the computing system. Feedback may be transmitted optically (e.g., light signal or displayed image), mechanically (e.g., haptic feedback, touch feedback, force feedback, or the like), electrically (e.g., electrical stimulation), olfactory, acoustically (e.g., beep or the like), or the like or any combination thereof and in a variable or non-variable manner.
System 2000 also includes power system 2046 for powering the various hardware components and may include a power management system, one or more power sources, a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator and any other components typically associated with the generation, management and distribution of power in portable devices.
In some embodiments, peripherals interface 2016, one or more processors 2018, and memory controller 2020 may be implemented on a single chip, such as processing system 2004. In some other embodiments, they may be implemented on separate chips.
In addition to the foregoing, the system 2000 may include a secure processor 2040 in communication with a fingerprint sensor 2042, via a fingerprint I/O controller 2044. Secure processor 2040 may be implemented as one or more processing units. The operation of these various elements will now be described.
The fingerprint sensor 2042 may operate to capacitively capture a series of images, or nodes. When taken together, these nodes may form a fingerprint. The full set of nodes may be referred to herein as a “mesh.” Although the fingerprint sensor is described as operating capacitively, it is understood that this is an example. In various implementations, the fingerprint sensor may be optical, capacitive, ultrasonic, and/or any other such mechanism for capturing one or more images and one or more portions of one or more fingerprints. It is understood that the embodiments discussed herein may operate with any suitable fingerprint sensor, including swipe or strip sensors, array or other two-dimensional sensors, and so on.
Each node in the mesh may be separately captured by the fingerprint sensor 2042, which may be an array sensor. Generally, there is some overlap between images in nodes representing adjacent portions of a fingerprint. Such overlap may assist in assembling the fingerprint from the nodes, as various image recognition techniques may be employed to use the overlap to properly identify and/or align adjacent nodes in the mesh.
Sensed fingerprint data may be transmitted through the fingerprint I/O controller 2044 to the processor 2018 and/or the secure processor 2040. In some embodiments, the data is relayed from the fingerprint I/O controller 2044 to the secure processor 2040 directly. The fingerprint data is encrypted, obfuscated, or otherwise prevented from being accessed by an unauthorized device or element, by any of the fingerprint sensor 2042, the fingerprint I/O controller 2044 or another element prior to being transmitted to either processor. The secure processor 2040 may decrypt the data to reconstruct the node. In some embodiments, unencrypted data may be transmitted directly to the secure processor 2040 from the fingerprint controller 2044 (or the sensor 2042 if no controller is present). The secure processor may then encrypt this data.
Fingerprint data, either as nodes or meshes, may be stored in the computer-readable medium 2001 and accessed as necessary. In some embodiments, only the secure processor 2040 may access stored fingerprint data, while in other embodiments either the secure processor or the processor 2018 may access such data.
FIG. 3 is a flow chart 3000 illustrating a first tracking method embodiment. In the method illustrated by flow chart 3000, the electronic device 1000 reports tracking information in response to a specific request. The specific request may be sent by a computer associated with a person or group that is tracking the device user. For example, the specific request may be from a parent's computer that is tracking the location of a child, a court system computer that is tracking compliance with a restraining order or house arrest boundary, or a governmental computer that is tracking compliance with diplomatic geographic restrictions.
Initially, in operation 3004, the tracking module 2039 receives a tracking request from a computing device that is remote from the electronic device. By way of example, operation 3004 may include the communication module 2024 handling an internet protocol message that contains the tracking request. The internet protocol message may be a wireless communication that is received at the electronic device 1000 through the RF circuitry 2008. Alternatively, the communication module 2024 may handle a communication received at the electronic device 1000 through a wired connection. Once the message is received by the communication module 2024, the communication module 2024 may forward the tracking request to the tracking module 2039 for processing. Once the tracking module 2039 receives the tracking request in operation 3004, control may pass to operation 3008.
In operation 3008, the tracking module 2039 further processes the tracking request by determining the identity of the device user. Here, the tracking module 2039 uses biometric information that is acquired from the user of the electronic device 1000. In one embodiment, the tracking module 2039 uses fingerprint data acquired through the operation of the fingerprint sensor 2042. FIGS. 5-7 illustrate various methods of identifying the device user by fingerprint or other biometric data. In the method illustrated in FIG. 7, the tracking module 2039 uses stored biometric information that was acquired in a recent biometric scan. In other embodiments, the tracking module 2039 may initiate a fresh biometric scan so that the tracking report correctly identifies the current user of the electronic device. For example, in the method illustrated in FIG. 5, the tracking module 2039 initiates a biometric scan discreetly, without the user knowing that the scan is taking place. In the method illustrated in FIG. 6, the tracking module 2039 alerts the user that a scan is required and prompts the user to enter biometric information. Once the tracking module 2039 determines the identity of the device user in operation 3008, control may pass to operation 3012.
In operation 3012, the tracking module 2039 determines the location of the electronic device. Operation 3012 may include determining the location of the electronic device 1000 through the operation of an on-board location awareness subsystem. In one embodiment, the location awareness subsystem of the electronic device 1000 is a global positioning system. Once the tracking module 2039 determines the location of the electronic device 1000 in operation 3012, control may pass to operation 3016.
In operation 3016, the tracking module 2039 reports the user identity and device location information. By way of example, the tracking module 2039 may forward a tracking report to the communication module 2024. The tracking report may include the device user information acquired in operation 3008 and the location information acquired in operation 3012. The communication module 2024 may then format an internet protocol message that includes the tracking report. The communication module 2024 may transmit the message to the remote computer that submitted the request by wired or wireless communication.
FIG. 4 is a flow chart 4000 illustrating a second tracking method embodiment. In the method illustrated by flow chart 4000, the electronic device 1000 reports tracking information on a periodic basis. Tracking information may be included in periodic tracking reports that are sent by the electronic device 1000 to a computer system associated with a person or group that is tracking the device user. For example, the electronic device 1000 may periodically send tracking reports to a parent's computer that is tracking the location of a child, a court system computer that is tracking compliance with a restraining order or house arrest boundary, or a governmental computer that is tracking compliance with diplomatic geographic restrictions.
Initially, in operation 4002, the tracking module 2039 sets a timer. By way of example, the timer may be a countdown timer implemented in either hardware or software. The tracking module 2039 may set the timer to correspond to a desired time interval between operations of sending a periodic tracking report. The tracking module 2039 may be initially programmed to set the timer to a default time interval, which can be adjusted by a user or administrator if desired.
Operation 4006 may be executed following operation 4002. In operation 4006, the tracking module 2039 determines if the timer is expired. If the timer is not yet expired, the tracking module 2039 again executes operation 4006. In this way, the tracking module 2039 loops or otherwise remains suspended until the timer expires. If, in operation 4006, the tracking module 2039 determines that the timer is expired, control passes to operation 4008.
In operation 4008, the tracking module 2039 begins compiling data to be sent in a tracking report by determining the identity of the device user. Here, the tracking module 2039 uses biometric information that is acquired from the user of the electronic device 1000. In one embodiment, the tracking module 2039 uses fingerprint data acquired through the operation of the fingerprint sensor 2042. FIGS. 5-7 illustrate various methods of identifying the device user by fingerprint or other biometric data. Once the tracking module 2039 determines the identity of the device user in operation 4008, control may pass to operation 4012.
In operation 4012, the tracking module 2039 determines the location of the electronic device 1000. Operation 4012 may include determining the location of the electronic device 1000 through the operation of an on-board location awareness subsystem. In one embodiment, the location awareness subsystem of the electronic device is a global positioning system. Once the tracking module 2039 determines the location of the electronic device 1000 in operation 4012, control may pass to operation 4016.
In operation 4016, the tracking module 2039 reports the user identity and device location information. By way of example, the tracking module 2039 may forward a tracking report to the communication module 2024. The tracking report may include the device user information acquired in operation 4008 and the location information acquired in operation 4012. The communication module 2024 may then format an internet protocol message that includes the tracking report. The communication module 2024 may transmit the message to the remote computer that receives the periodic tracking reports by wired or wireless communication. Once the tracking module sends the tracking report in operation 4016, control may again pass to operation 4002 where a timer is set for the next periodic tracking report.
FIG. 5 is a flow chart illustrating a first method of determining the identity of a device user. In the method illustrated by flow chart 5000, the electronic device 1000 conducts a biometric scan as part of compiling information for a tracking report.
