Managing tethered data traffic over a hotspot network
Presented is a system and method for controlling access to a mobile hotspot on a mobile device utilizing a hotspot management application. The method includes detecting unauthorized data traffic over a tethered link between the mobile device and a tethered device by analyzing a signature of the unauthorized data traffic. Analyzing the signature of the unauthorized data traffic may be carried out utilizing a rules engine, where the rules engine is based on one or more carrier controlled tethering policies and one or more user controlled tethering policies. Detecting unauthorized data traffic may further include detecting an unauthorized tethering application on the mobile device utilizing a database of known unauthorized tethering applications. The method further includes controlling the unauthorized data traffic. The method additionally includes redirecting a user of the mobile device to a captive portal for authorized tethering plan support.
1. A method for controlling access to a mobile hotspot on a mobile device utilizing a hotspot management application, said method comprising:
detecting an unauthorized data traffic over a tethered link between said mobile device and a tethered device by obtaining a signature of said unauthorized data traffic and determining that said signature does not match an authorized signature stored in a memory of said mobile device, wherein said obtaining said signature of said unauthorized data traffic is carried out utilizing a rules engine, and wherein said rules engine is based on one or more carrier controlled tethering policies and one or more user controlled tethering policies;
determining, using said signature of said unauthorized data traffic, an identity of an unauthorized application or device generating said unauthorized data traffic, wherein said determining of said identity of said unauthorized application or device includes looking up said signature of said unauthorized data traffic in a database; and
redirecting, in response to said detecting, a user of said mobile device to a captive portal for carrier-authorized tethering data plan support.
2. The method of claim 1 , further comprising:
detecting when said hotspot management application is not installed on said mobile device; and
automatically reinstalling said hotspot management application on said mobile device.
3. The method of claim 1 , wherein said signature of said unauthorized data traffic is a hash of one of a binary of said unauthorized application or device, an executable filename, and a brand product name of said unauthorized application or device.
4. The method of claim 1 , wherein said mobile device is one of a smartphone, a personal computer, a tablet computer and a personal digital assistant.
5. The method of claim 1 , wherein said tethering link comprises one of a USB connection, a Bluetooth connection, a WiFi AP connection, a WiFi direct connection and an Ethernet connection.
6. The method of claim 1 , further comprising reporting said signature of said unauthorized data traffic to a central server.
7. The method of claim 1 , wherein said captive portal is hosted on said mobile device.
8. A mobile device for controlling access to a mobile hotspot utilizing a hotspot management application, said mobile device comprising:
a memory storing an authorized signature;
a hardware processor configured to:
detect an unauthorized data traffic over a tethered link between said mobile device and a tethered device by obtaining a signature of said unauthorized data traffic and determining that said signature does not match said authorized signature stored in said memory of said mobile device, wherein said obtaining said signature of said unauthorized data traffic is carried out utilizing a rules engine, and wherein said rules engine is based on one or more carrier controlled tethering policies and one or more user controlled tethering policies;
determine, using said signature of said unauthorized data traffic, an identity of an unauthorized application or device generating said unauthorized data traffic, wherein determining said identity of said unauthorized application or device includes looking up said signature of said unauthorized data traffic in a database; and
redirect, in response to detecting, a user of said mobile device to a captive portal for carrier-authorized tethering data plan support.
9. The mobile device of claim 8 , wherein said processor is configured to:
detect when said hotspot management application is not installed on said mobile device; and
automatically reinstall said hotspot management application on said mobile device.
10. The mobile device of claim 8 , wherein said signature of said unauthorized data traffic is a hash of one of a binary of said unauthorized application or device, an executable filename, and a brand product name of said unauthorized application or device.
11. The mobile device of claim 8 , wherein said mobile device is one of a smartphone, a personal computer, a tablet computer and a personal digital assistant.
12. The mobile device of claim 8 , wherein said tethering link comprises one of a USB connection, a Bluetooth connection, a WiFi AP connection, a WiFi direct connection and an Ethernet connection.
13. The mobile device of claim 8 , wherein said processor is configured to report said signature of said unauthorized data traffic to a central server.
14. The mobile device of claim 8 , wherein said captive portal is hosted on said mobile device.
