TCCService?

Hi, guys idk if someone have any info about the Disgnostic & Usage reports but right now in this section on my iphone 5s using iOS 7.1 it appears a log called

"TCCService-xxxx-xx-xx-... .plist"

and i search in google and i cant find anything about this log, wich it seems odd

the only thing i can understand about the log inside is that it talks about Whatsapp being the responsible...

Someone can explain me what is this TCCService?

Thanks!
