Digital identity is the black hole of the internet. Our online lives simply aren’t protected by a system without strong authentication. Killing the password is Mission One for security professionals because they’re so readily stolen through phishing attacks and malware.

Banks, of course, look to repayment history to make such determinations but in much of the world, banking relationships and repayment track records are few.

I recently had the time and opportunity to bone up on machine learning.  The opportunity that presented itself was a 10-week on-line course taught by a well known Stanford Computer Science professor, Andrew Ng.  The course, offered by coursera.org included lectures, quizzes, and programming exercises.
