web security technologies issue paper, v. 4

Hi All,

Attached is a new version of my issue paper on web security technologies. I revised and augmented it according to recommendations I received during last week's teleconference.
New content includes descriptions of security tokens and keygen, an HTML5 element. I also added a section on ease-of-use ideas, i.e.:

*     Allow alternative authentication factors, such as:

o  location (e.g., user's home or place of employment);

o  presence of a trusted family member or friend, who is detected, for examples, by a wearable biometric device or by a mobile device

*     Develop and use common sets of vocabulary and iconography across web security technologies.
I look forward to your review and suggestions.

John
