Is there a way to prove the ownership of an address without spending bitcoins? I Imagine something like signing some given data with the private key - how much would that weaken the security of the bitcoins behind the Address? Any good read on this topic is welcome!

Removed a comment here, because using a spoofed link to refer to lmgtfy is rude. Please rather ask, whether OP has tried looking for "correct keyword", or just flag it as the corresponding duplicate. – Murch – 2014-09-18T21:49:36.583
