Concern: Understanding Net Users' Attitudes About Online Privacy
by Lorrie Faith Cranor, Joseph Reagle, and Mark S. Ackerman
People are concerned about privacy, particularly on the
Internet. While many studies have provided evidence of this concern,
few have explored the nature of the concern in detail, especially for
the online environment. With this study, we have tried to better
understand the nature of online privacy concerns; we look beyond the
fact that people are concerned and attempt to understand how they are
concerned. We hope our results will help inform both policy decisions
as well as the development of technology tools that can assist
Internet users in protecting their privacy.
We present results here from the analysis of 381 questionnaires
completed between November 6 and November 13, 1998 by American
Internet users. The sample was drawn from the FamilyPC
magazine/Digital Research, Inc. Family Panel. While this is not a
statistically representative sample of US Internet users, our
respondents are heavy Internet users, and quite possibly lead
innovators. As such, we believe that this sample is important for
understanding the future Internet user population.

A Proposed Extension to HTTP : Digest Access Authentication,
by J. Hostetler, J. Franks, P. Hallam-Baker, A. Luotonen, E. Sink, L. Stewart.
Internet Draft, dated 20 December 1995.
The protocol referred to as "HTTP/1.0" includes specification for a Basic
Access Authentication scheme. This scheme is not considered to be a secure
method of user authentication, as the user name and password are passed
over the network in an unencrypted form. A specification for a new
authentication scheme is needed for future versions of the HTTP protocol.
This document provides specification for such a scheme, referred to as
"Digest Access Authentication". The encryption method used is the RSA Data
Security, Inc. MD5 Message-Digest Algorithm.
