Data Tainting
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
- In principle one could selectively control access but in practice it never worked as too hard to “untaint”
Tainting was extremely clumsy and has been disabled in NN4, in favor of signed scripts
