I got them from Silicon Power (Global)

I think Silicon Power is really weird and this is the very first time that I encounter such a company.  In the first email they asked for my particulars like address and telephone number, then another email asking for my date of birth and passport number, then another email asking for a copy of my passport.  Why should they be asking for a copy of my personal passport?  How can I trust them.  I'm not at all comfortable to give it to some stranger in the foreign country whom I don't know.  Really scary.
