Gidon Gershinsky updated PARQUET-1376:
--------------------------------------
Description:
Data obfuscation in sensitive columns - for users without access to column
encryption keys.
# Implement on top of [basic Parquet
encryption|https://github.com/apache/parquet-format/blob/encryption/Encryption.md]
# Built-in support for multiple masking mechanisms, with different trade-off
between data utility, leakage, and size/throughput overhead
# Provide interface for plug-in custom masking mechanism
# Enable storing multiple masked versions of the same column in a file
# Provide readers with explicit list of column’s masked versions in a file
# Enable readers to select a masked version of a column
# Stretch: Implement tools for analysis of file data privacy properties and
information leakage
# Stretch: Leverage privacy analysis tools for tuning file data anonymity
# Optional: Support aggregated obfuscation
was:
Anonymity layer for hidden columns
# Different data masking options
** per-cell
** aggregated (average, etc)
# Reader notification on data access status
# Providing readers with a choice of masking options (if available)
> Data obfuscation layer for encryption
