Protected TrustLogo Design Contest

Thanks for your entries! Of these, I like #15 best, because it has depth (shown by the shadow underneath) and shows motion, but is still simple. #17 has too much going on with the two orbit rings. I like the shading on #16 - could that be applied to #15?

Not sure I like the lock though.
