Hi Gene!
My blog is a arunning, sequential series of posts, taken from a book I wrote. But rather than publishing it as on old-school, I'm trying to present this information in blog form in the hopes of engaging others who have experience doing these types of things. Any uncertainty can probably be cleared up by reading previous posts you may have missed.
Addressing your specific question:
"ACTUAL YOU"- Is the living, breathing flesh-and-blood entity currently reading this post-- regardless of your name or how you are known to the government.
"PERSON OF RECORD"- This is Actual You, as known by your "real name." The name by which you are plugged into officialdom, such as the DMV and your state's Bureau of Vital Statistics.
"VIRTUAL SELF"- A made-up name (or names) underwhich you might be living, working or transacting business, or by which you socially introduce yourself.

Total privacy is probably impossible, especially if the Government has a specific intrest in you, specifically. For the rest of us, I believe that sufficient privacy can be achieved through obfuscation and misdirection to meet the needs of most. Thanks for commenting, and keep reading!
