Step 1 Large-scale LLM-based de-anonymization technology

Step 2 Anonymous post identity exposure risk assessment
→
Step 3 Writing style disguise training and automated transformation

Problem

As LLM-based de-anonymization technology advances, simply changing usernames no longer provides sufficient protection. When whistleblowing, writing company reviews, or expressing sensitive opinions, users need to consciously alter their usual writing style, but style transformation is not intuitive and difficult for non-experts to perform on their own. Reading academic papers on stylometry and self-applying takes 30 minutes to an hour per piece, and even then there is no way to verify effectiveness.

Solution

(1) Analyze the user's typical writing patterns to generate a 'writing fingerprint report,' (2) auto-paraphrase input text to maximize divergence from the user's fingerprint, and (3) provide an interactive coaching mode showing before/after similarity scores.

Target: Heavy users of anonymous workplace communities like Blind and Jobplanet (ages 25-45), public sector and enterprise employees considering whistleblowing
Revenue Model: SaaS Monthly Subscription at $5.15/month per account, 3-day Free Trial, enterprise group license at $3.00/person/month (10+ users)
Ecosystem Role: Education
MVP Estimate: 2_weeks
