SNS Privacy Exposure Analyzer

2.95

Derivation Chain

Step 1 LLM-powered large-scale de-anonymization technology
→
Step 2 Unintentional personal information exposure risk on social media
→
Step 3 Comprehensive privacy score calculation from SNS posts

Problem

Active social media users in their 20s-30s (working professionals posting on Instagram, Twitter, and blogs) are unaware that LLM-based aggregate analysis of their public posts can infer their residential area, workplace, commute route, family relationships, and income level. While individual posts appear harmless, collective analysis of hundreds of posts can build an identity-level profile. This increases the risk of stalking, phishing, and social engineering attacks, yet no self-assessment tool exists.

Solution

(1) Analyze user's public SNS accounts (Instagram, Twitter, blogs) and generate a Report of inferable personal information (residence, workplace, family, schedule patterns, etc.), (2) Display risk scores per category and show 'which posts contributed to this inference,' (3) Recommend deletion or privacy setting changes for high-risk posts.

Target: Active SNS users (working professionals ages 20-35), job seekers (who need to manage public profiles), influencer managers
Revenue Model: Basic assessment free (top 5 risk items), full Report at 19,000 KRW (~$14), Monthly Subscription with weekly auto-scan at 39,000 KRW/month (~$29)
Ecosystem Role: Consumer
MVP Estimate: 2_weeks
