It means that your pictures are actually of yourself.
You are stating that you have been "authenticated" or "verified".
The process is you have to send in a picture of your real government ID, a picture of you holding the same government ID and a picture of you holding a paper with your work name, today's exact date and the word Eros or Eros Toronto (whatever city you are advertising in, mainly).
They get back to you pretty quickly. They just compare your photos with your advertisements and if they are a similar match, you get authenticated.
