A Biometrics Based Secure Communication Scheme for Bluetooth Environment
Mostafa Akhavan-E-saffar · 2011
A novel personnel authentication and verification system for devices communicating through Bluetooth protocol has been proposed in this paper. Unlike existing verification systems which provide password or a PIN as a key, the system uses biometrics features as a key. In the implementation of the scheme, ridges and bifurcation based parameters are derived to generate a 128 bit Bluetooth pairing PIN In this paper a unique translational and rotational invariant feature set has been developed. These extracted feature data, unlike traditional systems which include the extracted data into payload, is used for device connection by generating the 128 bit PIN the system performance is analyzed using the pairing PIN for inter- sample and intra-sample recognition To validate the stability of the system the performance is analyzed with external samples which are not a part of the internal database . The offices of yesterday were a mesh of wired cables which often resulted in confusion with the exponential growth in peripheral devices. With so many devices like fax machines, printers, desktops, laptops, landline phones, the hazard and the clutter associated with the cables could not be overlooked . Bluetooth as a wireless network protocol provides a low-cost solution, for a wireless and cable free work area. Most of the electronic devices which are widely and commonly at workplaces, home and commercial establishments are Bluetooth enabled. the Bluetooth devices when connecting to each other follow the Bluetooth protocol where two devices share a common pairing key. the pairing keys chosen are based on choice of the user and are easy to be hacked and use by impostors, which can lead to serious security issues in places where high level of security is required. Biometric features provide the capability of a secure authentication because of the uniqueness associated with them. Among the extractable and collectible features, fingerprints have acquired widespread acceptance because of the ease associated with their collectibility and uniqueness. Other biometrics features are also widely used, but have certain disadvantages associated with them . A system which can combine the wireless connectivity of the Bluetooth with the user- specific advantage of biometrics can provide a solution for scenarios, where high level security is required. Suppose, a user enters a high security wireless area and he/she wants to access the database of the system. If he/she happens to be a legitimate user, he/she can pair with the database master device and become a part of the whole set-up. As opposed to the other valid and established systems, the system will use the biometric data to generate the pairing key between the two devices. Thus the devices connected are not only permitting a legal user, also the slave device can be synchronized as per the user logging in, into the system .
