How do I keep my personal data secure in Chrome Browser and Dropbox on my work computer?

Question

dropbox

On my work computer, I work in Google Chrome in my personal profile. I want to restrict access to my personal profile so that no one can see saved passwords and bookmarks. The master password depends on the login password, and this password can easily be changed by the administrator.
Are there any solutions for using google chrome from a flash drive (how can I screw it up)?
Is it possible to block access to the information saved in the profile?
All the same goes for dropbox
Thank you!
