ConvoProtect is a tweak which is to be officially launched in Cydia for iDevice owners and it will allow you to secure individual conversations of the Messages application. As you can already see from the image above, the tweak has a settings menu available in the Settings application of our iDevices, through which the phone numbers can be set for which the protection offered by it is activated.
For now, it is not known when it will be available for download ConvoProtect, but it will work on all iDevices that have iMessage activated and I will return with details when it is officially available in Cydia.
