Over at UMPCPortal last week I took a long look at Windows 8 security features. One of the weak-points in my opinion is authentication. It’s single-channel, requires no proof of ‘personal presence’ and it leaves the user to choose the level of security. Poor passwords are a killer and as a result I’ve been looking at alternative and two-stage solutions. PalmSecure is a palm-vein detection technology and it’s pretty much the best technology out there for laptops right now.
