Need help interpreting CAIPS Notes

Hello Everyone,

I had done my medical on October, 2009 and paid the RPRF fees at the same time. Then I was called for Interview on Aug 2010 and till now no news from the Visa Office. I had applied for CAIPS and below is the line i would like your feedback on.

PAPER FILE SENT TO: PEB BF FILE TO: HII ON 24-03-2011

Previous to this line, I can read clearly where it has been mentioned that my application was approved and send medical and ask for right of permanent residency fees. To my understanding it is the security check that is taking long. On the CAIPS it is also mentioned that verification has been done by local office (visa office in my country) and confirmed geniune. What else are they waiting for or what are they actually verifying? Can you tell what the above line means? Is PEB a visa office or a visa officer. I saw lot of writing from HII so i guess thats a VISA officer. There is also one line in the CAIPS where PEB has written comments to sent my file to KAC to be grouped. Let me know...
