_fpsd user running lskdd process group? Who is this, Have I been hacked ?

Who is this User (_fpsd) on my activity monitor? Also what is the "lskdd process group"? From what ive found fpsd has to do with FairPlay streaming. Also ive found that lskdd is an iPhone Local System Kernel Debug Daemon". I checked my system preferences under users and groups nowhere does it say show fpsd so im worried my computer is being remotely accessed. Ive tried Force quitting the process in activity monitor but it just instantly turns back on. Im desperate to find out what this is. Please help!
