I have been through this several times. There's never any advantage to you revealing your current salary. No company is ever going to reject you because you didn't tell them your current salary. So just politely tell the recruiter that you don't want to reveal it. If they insist, just tell them what your salary expectation is (this should give them an idea of what kind of offer you'd be willing to accept which is all they should care about).
