designed to distinguish genuine human-written content from AI-generated or AI-assisted text. The system focuses on analyzing **writing behavior** alongside **statistical and linguistic characteristics** of the text to establish reliable authorship verification. - -This repository represents the **design and conceptual foundation** for the Vi-Notes system. - ---- - -## Motivation - -With the widespread availability of AI writing tools, verifying true human authorship has become increasingly challenging. Most existing detection methods rely primarily on textual analysis, which can be inconsistent and easy to bypass. - -Vi-Notes approaches this problem by combining: -- Behavioral signals from the writing process -- Statistical analysis of the written content -- Correlation between how content is written and what is written - ---- - -## Core Idea - -Human writing naturally includes: -- Variable typing speeds -- Pauses during thinking -- Revisions during idea formation -- Irregular sentence structures -- A relationship between content complexity and editing frequency - -AI-generated or pasted text often lacks these behavioral signatures. - -Vi-Notes is designed to capture and analyze these characteristics to assess authorship authenticity. - ---- - -## Key Features - -### Writing Session Monitoring -- Capture keystroke timing metadata (not raw key content) -- Track pauses, deletions, edits, and writing flow -- Detect pasted or externally inserted text blocks - -### Behavioral Pattern Analysis -- Pause distribution before sentences and paragraphs -- Typing speed variance -- Revision frequency relative to text complexity -- Micro-pauses around punctuation and structural boundaries - -### Textual Statistical Analysis -- Sentence length variation -- Vocabulary diversity metrics +### Database +MongoDB will automatically create the `vi-notes` database and required collections. + +## 🔌 API Endpoints + +### Session Management +```http +POST /session/start +Content-Type: application/json + +{ + "userId": "string" +} + +Response: +{ + "status": "ok", + "sessionId": "string", + "baseline": { + "sessionCount": number, + "status": "no_baseline|new|developing|mature", + "features": {...} + } +} +``` + +```http +POST /session/end +Content-Type: application/json + +{ + "sessionId": "string" +} + +Response: +{ + "status": "ok", + "session": { + "sessionId": "string", + "userId": "string", + "duration": number, + "eventCount": number, + "startTime": "ISO string", + "endTime": "ISO string" + }, + "finalBaseline": {...} +} +``` + +### Event Processing +```http +POST /events/batch +Content-Type: application/json + +{ + "events": [ + { + "sessionId": "string", + "type": "keydown|keyup|paste|delete", + "key": "string", + "timestamp": number, + "pasteLength": number + } + ] +} + +Response: +{ + "status": "ok", + "features": {...}, + "detection": { + "score": number, + "confidence": "low|medium|high", + "flags": ["array of flags"], + "explanation": "string" + }, + "baseline": { + "comparison": {...}, + "summary": {...} + } +} +``` + +### Reporting +```http +GET /report/:sessionId + +Response: +{ + "status": "ok", + "report": { + "sessionId": "string", + "userId": "string", + "sessionInfo": {...}, + "analysis": { + "features": {...}, + "detection": {...}, + "baselineComparison": {...}, + "overallRisk": "low|medium|high", + "confidence": number + }, + "events": number, + "generatedAt": "ISO string" + } +} +``` + +### Health Check +```http +GET /health + +Response: +{ + "status": "ok", + "database": "connected|disconnected" +} +``` + +## 🎯 Usage Example + +```javascript +// Start a session +const sessionResponse = await fetch('/session/start', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ userId: 'alice' }) +}); +const { sessionId } = await sessionResponse.json(); + +// Send typing events +const events = [ + { sessionId, type: 'keydown', key: 'H', timestamp: Date.now() }, + { sessionId, type: 'keydown', key: 'i', timestamp: Date.now() + 150 }, + // ... more events +]; + +await fetch('/events/batch', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ events }) +}); + +// End session and get report +await fetch('/session/end', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ sessionId }) +}); + +const reportResponse = await fetch(`/report/${sessionId}`); +const { report } = await reportResponse.json(); +console.log('Risk Level:', report.analysis.overallRisk); +``` + +## 🔍 Analysis Results + +### Detection Scores +- **0-30**: Genuine behavior (high confidence) +- **31-60**: Mixed indicators (medium confidence) +- **61+**: Suspicious behavior (low confidence) + +### Risk Levels +- **Low**: Authorship appears genuine +- **Medium**: Additional verification recommended +- **High**: Significant behavioral deviations detected + +### Baseline Status +- **no_baseline**: First session, establishing profile +- **new**: Building initial behavioral profile +- **developing**: Profile maturing with more sessions +- **mature**: Stable profile for reliable anomaly detection + +## 🧪 Testing + +### Run All Tests +```bash +# Backend tests +cd server +node test-e2e.js # End-to-end integration +node test-integration.js # API endpoint tests +node test-db.js # Database operations + +# Frontend development +cd client +npm run dev +``` + +### Manual Testing +1.
