How can a web user phone/skype someone with details in my database - the web user must not be able to access these details. The same question applies to messenger service and webcam.
Let me clarify. John, a member of the public, sees the picture of a lovely lady on my website and wants to speak to her. Obviously, I don't want him to know her number - unless she chooses to tell it to him. Is there a way to do it without spending an arm and a leg on hardware and suchlike. Also, I would need to keep track of usage for billing purposes.
For what it is worth, my favourite programming language is Delphi.
