Abstract

Disclosed herein is a system for configuring and setting up a one to one communication correspondence between a headset and a mobile device. The authentication PIN allows communication of the headset with only those devices that are authenticated using the PIN. A first software application and a second software application are provided on the mobile device and a headset respectively. The process of configuring the PIN access information on the headset using the first and second application comprises the step of establishing a secure communication link by completing challenge response sequence between the headset and the device using the currently prevailing PIN, transmitting a configuration set PIN from the device to the headset, enforcing reauthentication using the newly configured PIN, and establishing and locking a communication between the device and the headset based on the new personal identification number.

Claims

1. A method of configuring an authentication personal identification number on a headset, wherein said authentication personal identification number allows communication of the headset with only those devices that are authenticated using said authentication personal identification number, the method comprising the steps of:

providing a first application on a device;

providing a second application on the headset;

configuring the personal identification number access information on said headset using said first application and second application, further comprising the steps of;

establishing a secure communication link by completing challenge response interactions between the headset and the device, using a currently prevailing personal identification number;

transmitting a new configuration set personal identification number from said device to said headset, wherein said transmission is performed via a secure Bluetooth wireless communication channel; and

automatically enforcing reauthentication using said new configuration set personal identification number.

2. The method of claim 1, further comprising the step of establishing and locking a communication between the device and the headset, wherein said communication is established using the new configuration set personal identification number.

3. The method of claim 1, wherein said personal identification number access information can be configured multiple times.

4. The method of claim 1, wherein when said headset enters the coverage range of an unauthorized device, and a challenge response sequence with the headset is unsuccessful, the unauthorized device prompts a user of the unauthorized device to enter the authentication personal identification number for authenticating access to the headset.

5. The method of claim 1, wherein when said headset enters the coverage range of an authorized device, said authorized device is automatically authenticated to access the headset.

6. The method of claim 1, wherein more than one personal identification number is associated with the headset.

7. The method of claim 1, wherein said authentication personal identification number may be specific to a device, whereby said device uses said specific authentication personal identification number to gain access to the headset.

8. A method of altering a plurality of configuration parameters of a headset using a human machine interface of a device, the method comprising the steps of:

providing a first application on the device;

providing a second application on the headset;

configuring the parameters of said headset using said first application and second application, further comprising the steps of;

establishing a secure communication link by completing a challenge response sequence between the headset and the device, using a currently prevailing personal identification number; and

transmitting new values of said configuration parameters from said device to said headset, wherein said transmission is performed via a secure Bluetooth wireless communication channel.

9. A system for configuring an authentication personal identification number on a headset and establishing a one to one communication correspondence between said headset and a device operated by a user, comprising:

a first application provided on said device, said first application further comprises a first personal identification number configuration module;

a second application provided on the headset, said second application further comprising;

a second personal identification number configuration module and

a personal identification number identification module; and

a personal identification number storage means that stores permitted personal identification numbers;

a first Bluetooth transceiver located within the device and a second Bluetooth transceiver located within the headset that transfer Bluetooth packets between the headset and the device.

10. The system of claim 9, wherein said personal identification number storage means contains a memory unit and memory access means.

11. The system of claim 9, wherein said personal identification number storage means contains a memory access means, and wherein the device further comprises a memory unit that is accessed by said memory access means.

12. The system of claim 9, wherein in an attempt to establish a communication correspondence between the device and the headset, the user is required to input the unique personal identification number when prompted, wherein after authentication using the personal identification number, a communication correspondence is permitted between the device and the headset.

13. The system of claim 10, wherein the memory unit of the second application stores user profiles, headset information, personal identification number access information, currently prevailing personal identification number, the time at which the personal identification number was set, and details of the users permitted to change the personal identification number, and a list of all the permitted personal identification numbers.

14. The system of claim 9, further comprising a communication module that establishes authenticated communication, locks said authenticated communication for the entire duration of the connection, warns the user if the headset moves out of the coverage range, and disconnects existing connection after said duration.

15. A computer program product comprising computer executable instructions embodied in a computer-readable medium, said computer program product comprising:

a first computer parsable program code on a headset for conducting personal identification number identification and authentication procedures;

a second computer parsable program code on a device for conducting personal identification number identification and authentication procedures;

a third computer parsable program code for configuring the personal identification number access information on said headset, further comprising;

a fourth computer parsable program code for establishing a secure communication link by completing challenge response interactions between the headset and the device, using the currently prevailing personal identification number;

a fifth computer parsable program code for transmitting a new configuration set personal identification number from said device to said headset, wherein said transmission is performed via a secure Bluetooth wireless communication channel; and

a sixth computer parsable program code for automatically enforcing reauthentication using said new configuration set personal identification number.

16. The computer program product of claim 15, further comprising a seventh computer parsable program code for establishing and locking a communication between the device and the headset, wherein said communication is established using the new configuration set personal identification number.
