Abstract

A fingerprint table or other type of data structure including a plurality of entries may be provided, each entry including a transmitter fingerprint set of a respective network location. Determining whether a current network location is a network location known to a user device may include comparing a determined transmitter fingerprint set of the entity with the transmitter fingerprint set of one or more fingerprint table entries. A user interface may be provided that enables a user to control when a transmitter fingerprint set is determined, compared with fingerprint table entries and/or recorded.

Claims

1. A computer program product comprising:

at least one computer-readable storage medium;

said

computer-readable storage medium storing instructions that, as a result of being executed by a user device, instruct the user device to perform a method of assisting a user of a user device in recording a transmitter fingerprint set of a network location, the method comprising;

(a) providing a user interface to enable the user to initiate recording the transmitter fingerprint set of the network location, the initiation of recording being performed at least in part in response to receiving a signal;

(b) determining a transmitter fingerprint set of the network location;

(c) accessing an information source storing one or more transmitter fingerprint sets of one or more network locations; and

(d) determining that the determined transmitter fingerprint set does not match any of the transmitter fingerprint sets stored in the information source,

wherein the act (a) is performed in response to the act (d).

2. The computer program product of claim 1, wherein the act (a) comprises displaying a window to the user that indicates to the user an option of recording the transmitter fingerprint set of the network location.

3. The computer program product of claim 1, wherein the method further comprises:

(b) receiving a user input indicating to record the transmitter fingerprint set of the network location; and

(c) recording the transmitter fingerprint set in response to the input.

4. The computer program product of claim 3, wherein the act (c) comprises storing the transmitter fingerprint set in an information source configured to store transmitter fingerprint sets of network locations.

5. The computer program product of claim 1, wherein the method further comprises:

(b) determining that an information source configured to store one or more entries representing transmitter fingerprint sets does not include any entries,

wherein the act (a) is performed at least in part in response to the determination that the information source does not include any entries.

7. The computer program product of claim 1, wherein the act (a) is performed at least in part in response to a lapsing of a particular amount of time since a predetermined time.

6. A computer program product comprising:

at least one computer-readable storage medium said

computer-readable storage medium storing instructions that, as a result of being executed by a user device, instruct the user device to perform a method of assisting a user of a user device in recording a transmitter fingerprint set of a network location, the method comprising;

(a) providing a user interface to enable the user to initiate recording the transmitter fingerprint set of the network location, the initiation of recording being performed at least in part in response to receiving a signal;

(b) determining a transmitter fingerprint set of the network location;

(c) accessing an information source storing one or more transmitter fingerprint sets of one or more network locations; and

(d) determining that the determined transmitter fingerprint set matches one of the transmitter fingerprint sets stored in the information source to an extent that is above a matching threshold and below a re-record threshold,

wherein the act (a) is performed in response to the act (d).

8. A system for assisting a user of a user device in recording a transmitter fingerprint of a wireless access point, the system comprising:

a user interface to enable the user to initiate recording the transmitter fingerprint of the wireless access point, wherein the user interface is operative to enable the user to initiate recording the transmitter fingerprint in response to the user device receiving a signal from the wireless access point;

a fingerpoint determination module to determine a transmitter fingerprint of the wireless access point; and

an identification module operative to access an information source storing one or more transmitter fingerprints of one or more wireless access points, and operative to determine that the determined transmitter fingerprint matches one or the transmitter fingerprints stored in the information source,

wherein the user interface is operative to eable the user to initiate recording the transmitter fingerprint at least in part in response to the determination that the determined transmitter fingerprint matches one of the transmitter fingerprints stored in the information source.

9. The system of claim 8, wherein the user interface is further operative to receive a user input indicating to record the transmitter fingerprint of the wireless access point, and wherein the system further comprises a recording module to record the transmitter fingerprint in response to the input.

10. The system of claim 9, wherein the recording module is operative to store the transmitter fingerprint in an information source configured to store transmitter fingerprints of wireless access points.

11. The system of claim 8, wherein the system further comprises:

a checking module operative to determine that an information source configured to store one or more entries representing one or more transmitter fingerprints does not include any entries, and

wherein the user interface set is operative to enable the user to initiate recording the transmitter fingerprint at least in part in response to the determination that the information source does not include any entries.

12. A system for assisting a user of a user device in recording a transmitter fingerprint of a wireless access point, the system comprising:

a user interface to enable the user to initiate recording the transmitter fingerprint of the wireless access point, wherein the user interface is operative to enable the user to initiate recording the transmitter fingerprint in response to the user device receiving a signal from the wireless access point;

a fingerprint determination module to determine a transmitter fingerprint of the wireless access point; and

an identification module operative to access an information source storing one or more transmitter fingerprints of one or more wireless access points, and operative to determine that the determined transmitter fingerprint matches one of the transmitter fingerprints stored in the information source to an extent that is above a matching threshold and below a re-record threshold,

wherein the user interface is operative to enable the user to initiate recording the transmitter fingerprint at least in part in response to the determination that the determined transmitter fingerprint matches one of the transmitter fingerprints stored in the information source to an extent that is above the matching threshold and below the re-record threshold.
