i have a question fellas and for us its related to secure our data.

what i want is to pair one device to the phone and that device can only send files to the phone, apart from that i want to block all other devices from pairing with the phone and dont want any other device to send and receive files to phone. i also want to stop user from changing the settings of bluetooth in the phone
this is what we want for protecting our important customer data.
any package which gives such functionality or anything u guys think i can do to achieve this objective any thoughts or idea will be highly appreciated.
