Topic: Password: Owner or User? - Open or Security?

I use Adobe Acrobat 4 to create document. When I use Standard security handler for encrypting my handler I gave only Change Security Option password. I expected it not to open the document unless password is given.
Where does the viewer get the password string from? it is needed to decrypt the strings or streams.
Also, I don't understand what PDF 1.3 Spec talks about when it says owner or user after this.
Kindly elaborate on this. My main doubt is this: When there is no supplied password string how does a viewer open the PDF document and how can it be opened or decrypted?
The topic could be best understood with the PDF1.3 spec and with the use of a adobe writer.
