I don't know about that - there are plenty of jobs where you get frisked every time you come to and leave work. As long as you're working there voluntarily, it's up to the employer to define the conditions.
As for the OP, tell your boss to stick it on the collecting phones nonsense - it's not a invasion of privacy you're willing to put up with for this job, and so their choice is only whether to fire you or not - being it's a free country and all.
