I happened to hear from Peter Wayner that he’s got new editions of both his Disappearing Cryptography (third edition) and Translucent Databases (second edition) now available. Both books are now available from Amazon.
Since the advent of PCI-DSS and increasing concerns about data breaches involving personal information, I’m sure Peter’s techniques are becoming much more widely read – and applied! See my March 14, 2005 post about a talk that Peter gave at Stanford that day. See also Peter’s web site and this list of recent articles he’s written for the New York TImes.
