Stylometric Identification

Threat

Adversaries use stylometric analysis (Writeprints, JStylo) to identify the author of anonymous text by analysing sentence length, vocabulary, punctuation patterns, and other linguistic features.

Countermeasure: StyloScrubber

The StyloScrubber normalises text against a generic frequency table:

• Adjusts average sentence length to a configurable target
• Constrains vocabulary to a target size
• Smooths punctuation distribution

shadowforge scrub --input article.txt --output scrubbed.txt \
  --avg-sentence-len 12 --vocab-size 800

Or inline during embedding:

shadowforge embed --input article.txt --cover photo.png --output stego.png \
  --technique lsb --scrub-style

Residual Risk

Stylometric scrubbing is statistical and partial. A determined adversary with a large corpus of the author’s known writing may still identify residual patterns. This is a risk-reduction measure, not a guarantee of anonymity.
