The present invention generally relates to wireless terminal security, and more particularly relates to a method and apparatus for facilitating contact between a finder of a misplaced wireless terminal and an authorized user of the wireless terminal.
As the popularity of wireless terminals, such as cellular phones, smartphones, personal digital assistants (PDAs), laptops, etc, continues to grow, these devices are becoming more and more ubiquitous. Users often carry their wireless terminals with them at all times. Such widespread use has heightened concern for loss and theft of wireless terminals. This concern is amplified by the personal and confidential nature of the data that is often stored on these devices.
To protect valuable data, wireless terminals are often passcode-locked to prevent unauthorized access to user data. Such passcodes may include an alphanumeric password, or a predefined touchscreen gesture, for example.
As a further security measure, prior art devices have also included various additional features, such as permitting a remote wipe of a lost phone, or permitting remote initiation of a lock screen on a lost phone. Such security measures operate under the assumption that a finder of a lost wireless terminal may act maliciously upon finding the lost terminal to misuse data, possibly using the terminal to engage in theft or to incur substantial billing charges.
Methods and apparatus for facilitating contact between a finder of a misplaced wireless terminal and an authorized user of the wireless terminal, and/or for providing information for returning the misplaced wireless terminal are disclosed.
An exemplary method facilitates communication between a finder of a misplaced passcode-locked wireless terminal and an authorized user of the wireless terminal. According to the method, at least one menu option is presented to the finder for contacting the authorized user via a wireless communication network with which the wireless terminal is associated. The at least one menu option is accessible from a lock screen of the wireless terminal without entry of the passcode. Responsive to the finder selecting one of the at least one menu options, a communication is initiated between the finder and the authorized user via the wireless communication network. A corresponding wireless terminal operable to implement this method is also described.
An example method that is applicable to both passcode-locked and non passcode-locked wireless terminals facilitates communication between a finder of a misplaced wireless terminal and an authorized user of the wireless terminal. At least one menu option is presented to the finder for contacting an authorized user via a wireless communication network with which the wireless terminal is associated. Responsive to the finder selecting one of the at least one menu options, predefined contact information for the authorized user is used to initiate a communication between the finder and the authorized user via the wireless communication network, with the at least one menu option and the initiated communication hiding the predefined contact information from the finder.
In one or more of the methods described above, the step of presenting to the finder at least one menu option for contacting the authorized user of the wireless terminal includes presenting a menu option for each of a plurality of different contact methods.
In another exemplary method, information for returning a misplaced wireless terminal to an authorized user of the wireless terminal is provided to a finder of the misplaced wireless terminal. The wireless terminal receives a message from the authorized user indicating that the wireless terminal has been misplaced. Responsive to the received message, communication functionality of the wireless terminal is disabled, and a message is presented on a display of the wireless terminal that provides information for returning the wireless terminal to the authorized user. A corresponding wireless terminal operable to implement this method is also described.
Of course, the present invention is not limited to the above features and advantages. Indeed, those skilled in the art will recognize additional features and advantages upon reading the following detailed description, and upon viewing the accompanying drawings.
In one or more embodiments, the present invention facilitates communication between a finder of a misplaced wireless terminal and an authorized user of that terminal, while simultaneously protecting the identity of both the finder and the user. As will be discussed below in greater detail, for passcode-locked wireless terminals, the finder is able to initiate a communication with the user without having to enter the passcode.
Referring now to the drawings, the present invention will be described in the context of a communication network 10 as shown in
The PSTN 14 is a circuit-switched network providing both voice and data communications, and in particular it provides voice service to traditional telephones such as telephone 22. PDN 16 includes a packet-switched network that implements known protocols, such as conventional Internet protocols, for routing packets of data from one end point to another. PDN 16 may include a public or private network, and may be a wide-area network, a local-area network, or a combination of both. The Internet is one well-known example of a PDN 16. The PDN 16 facilitates communication between personal computer (PC) 24 and server 26.
The wireless terminal 20 has one or more authorized users 28. An authorized user 28 could include an owner of a wireless terminal 20, and/or someone who is granted permission by the owner to use the terminal for an extended period of time (e.g. a family member or an employee using a company-owned phone), for example. A company information technology (IT) employee tasked with maintaining the security of company wireless terminals may also be considered an authorized user.
The terminal 20 may be passcode-locked to prevent unauthorized access from unauthorized users, such as a finder 30 of the wireless terminal 20. The passcode may include an alphanumeric password, or a predefined touchscreen gesture, for example. Thus, if the terminal 20 is misplaced and the finder 30 locates the misplaced terminal 20, the secret passcode can prevent the finder 30 gaining unauthorized access to the contents of the terminal 20, or from using the terminal 20 without authorization.
The wireless terminal 30 includes features to facilitate communication between the finder 30 and the authorized user 28, to provide the finder 30 information for returning the wireless terminal 20 to the authorized user 28, or both.
The “Return to Owner” option 42 may be present at all times on the lock screen 40 (or on a home screen for a non passcode-locked phone), for example. Alternatively, the option 42 may be remotely activated by the authorized user 28. In one or more embodiments, the presentation to the finder 30 of the menu option 42 for contacting the authorized user 28 of the wireless terminal 20 is performed responsive to receiving a message from the authorized user 28 indicating that the wireless terminal 20 has been misplaced. The message may be received as a Short Message Service (SMS) message, or via another remote mechanism, for example.
When the finder selects the option 42, the terminal 20 may either directly initiate a communication, such as a phone call, with the authorized user 28, or may instead present a secondary screen 44 that includes a plurality of menu options 46A-C to the finder 30 (see

The predefined telephone number may be updated on the wireless terminal 20 based on input from the authorized user 28. In one example the authorized user 28 may update that predefined number by directly messaging the lost wireless terminal 20 (e.g. via SMS). As another example, the authorized user 28 may use PC 24 to update a phone number database on the server 26, and the server 26 may communicate with the lost wireless terminal 20 to update the number. The server 26 to wireless terminal 20 communication may occur via a running daemon on the wireless terminal 20 that listens to IP communications on a predefined port, for example.
In some embodiments, initiating a communication between the finder 30 and the authorized user 28 includes preparing a message for the authorized user 28 responsive to input from the finder 30, and transmitting the message to the authorized user 28 via the wireless communication network 12. The message may be transmitted as an SMS message to the predefined telephone number or as an email to a pre-populated email address, for example.
Although SMS and email have been discussed above, it is understood that other types of message transmission methods could be used. For example, a message could be sent via an instant messaging program or a social networking service. Whatever the communication method used to transmit the message, the address of the authorized user 28 may be prepopulated to prevent the finder 30 from sending messages to other parties.
In some embodiments, the pre-populated email address (or other contact information for the user) may be remotely updatable by the authorized user 28 much like the update process for the predefined telephone number discussed above. However, in one or more embodiments, the wireless terminal 20 has a hard-coded email address, and the wireless terminal 20 sends an International Mobile Equipment Identity (IMEI) or mobile equipment identifier (MEID) of the wireless terminal 20 along with the message from that hard-coded email address to the server 26. Based on that received message and the enclosed IMEI or MEID, the server may look up a predefined contact method for the authorized user 28 and correspondingly initiate a communication to reach the authorized user 28.
The wireless terminal 20 may be configured to protect the privacy of both the finder 30 and the authorized user 28. For example, the menu options 42, 46 for contacting the authorized user 28 may hide the identity, contact information, or both of the authorized user 28. The finder 30 is unable to enter a phone number, but instead is limited to calling or sending an SMS message to the predefined phone number. Similarly, in email embodiments, the finder 30 is limited to emailing the authorized user 28 using the predefined (and invisible to the finder) email address. These features simultaneously protect the privacy of the authorized user 28, and prevent the finder 30 from calling anyone other than the authorized user (or an emergency number if emergency calling is enabled from the lock screen). Thus, in either the phone call or messaging embodiments, the wireless terminal 20 may be configured to hide the contact information used to contact the authorized user 28 from the finder 30
Dialing a phone number typically emits dual-tone multi-frequency (DTMF) sounds, such that each number dialed has a recognizable DTMF tone. In one or more embodiments, these DTMF tones may be muted when the wireless terminal 20 is dialing the phone number of the authorized user 28, so that the finder 30 is not able to ascertain the hidden phone number of the authorized user 28 by listening to the DTMF tones.

Although the methods 100, 200 have been illustrated and described separately, it is understood that they could both be performed by the same wireless terminal 20. That is, steps 104 and 204 could both be performed as part of initiating contact between the finder 30 and the authorized user 28.
Thus, in one or more embodiments the processor 80 is configured to present to the finder 30 of the wireless terminal 20 at least one menu option (e.g. menu options 42, 46) on a display for contacting the authorized user of the wireless terminal 20 via the wireless communication network 12. Responsive to the finder 30 selecting of one of the at least one menu options, the processor 80 is configured to initiate a communication between the finder 30 and the authorized user 28 via the wireless communication network 12.
If the wireless terminal 20 is passcode-locked, the at least one menu option is accessible to the finder 30 from the lock screen 40 of the wireless terminal 20 without the finder 30 having to enter the passcode. Additionally, for both passcode-locked and non passcode-locked terminals, the terminal 20 is operable to initiate the communication between the finder 30 and the authorized user 28 using predefined contact information for the authorized user 28, while hiding that predefined contact information from the finder 30.
In the same or another embodiment, the processor 80 is configured to receive, via the transceiver 84, a message from the authorized user 28 indicating that the wireless terminal 20 has been misplaced. Responsive to the received message, the processor 80 is configured disable communication functionality of the wireless terminal 20 and to present a message on a display of the wireless terminal, with the message providing information for returning the wireless terminal to the authorized user (see, e.g.,
Although the methods 100, 200 have been separately described, it is possible that the mobile terminal 20 may be operable to implement either one or both of the methods. In one example, upon misplacing the wireless terminal 20, the authorized user 28 could remotely select which of the methods to implement, and could communicate that selection to the wireless terminal using any of the methods described above (e.g., SMS message, via server 26, etc.).
Thus, the foregoing description and the accompanying drawings represent non-limiting examples of the methods and apparatus taught herein. As such, the present invention is not limited by the foregoing description and accompanying drawings. Instead, the present invention is limited only by the following claims and their legal equivalents.
