If you have an Alchemy-based firmware running on your home router, you can enable sshd so you can have an always-on ssh tunnel wherever you go.
I did this to my home router and had it all working in about 30 minutes. Most of that time was trying to figure out how to get putty to open a tunnel (and registering/configuring a No-IP dynamic dns account).
My point was that having a computer running 24/7 at home to use as a secure proxy when you are out in the field is a bit wasteful. The technical solution was fine - though I can't see many non-techies getting their heads around this. Why the down vote - pffffh.
2) Install Tunnelier on your laptop, flip to the Services tab and enable SOCKS at 127.0.0.1 and port 1337. Login in to your home computer.
3) Change Chrome target to chrome.exe --proxy-server=socks5://127.0.0.1:1337
Mostly used for obtrusive proxies though it will make you as secure as you are at your home network..
