Foil 99 Data Tainting

From Overview of Advanced JavaScript -- Web Scripting Language CPS616 Technologies of the Information Age -- Spring Semester 98. by Tom Scavo,Geoffrey C. Fox
Data tainting, an alternative to the Same Origin Policy, was experimentally implemented in NN3.0
Data tainting allows access to private data (e.g., history[] array) but forbids "export" of this data over the Internet
Both data and methods may be tainted
Tainting has been disabled in NN4, in favor of signed scripts
