Security for Bluetooth-Enabled Mobile Phones (Thesis)

Thanks to those who replied to my e-mail, and I'm so sorry because the topic for our thesis was changed by our professor.  I'm very sorry.

We have a new topic now; it's about 'mobile phone security for bluetooth enabled' (security for bluetooth-enabled mobile phones). We were asked to create software that could enable a mobile phone user to block access to the phone using bluetooth. 

Please help us.  I need it for our thesis, please.  Thanks.
