Empowering Global Food Security Through Data-Driven Intelligence

Live Demo | Documentation | API Reference | Community

Project Overview

Purpose

FoodSecurityNet is a production-ready, modular, full-stack web application designed to address global food insecurity by integrating agricultural, environmental, and socio-economic data to provide:

Personalized farming recommendations powered by AI
Interactive 3D agricultural visualizations using Three.js
Natural language queries through LLM integration
Real-time collaboration tools for farmers, policymakers, and NGOs
Data-driven insights for sustainable food systems

The Global Challenge

According to the Food and Agriculture Organization (FAO), approximately 700 million people face hunger annually. Climate change, inadequate agricultural practices, limited market access, and socio-economic barriers exacerbate this crisis, particularly in vulnerable regions like Sub-Saharan Africa and South Asia.

Our Solution

FoodSecurityNet bridges the gap between data and actionable insights by:

Aggregating multi-source data from FAO, USDA, NOAA, and local surveys
Applying AI/ML models to predict optimal farming strategies
Visualizing complex data in intuitive 3D maps and dashboards
Enabling collaboration among stakeholders in real-time
Personalizing experiences for diverse user types (MBTI-based)

Unique Value Proposition

Unlike traditional tools like QGIS (geospatial analysis) or FAO databases (agricultural data repositories), FoodSecurityNet:

Integrates agricultural, environmental, and socio-economic data in one platform
Predicts farming outcomes using AI/ML models
Visualizes data in interactive 3D environments
Collaborates with real-time multi-user sessions
Personalizes based on 16 MBTI personality types
Exports in multiple formats (PNG, SVG, STL, CSV, JSON)

Authentication & Authorization

Overview

FoodSecurityNet supports multiple authentication methods to accommodate different user types and security requirements.

Authentication Methods

1. Local Authentication (Email/Password)

Registration: POST /api/auth/register
Login: POST /api/auth/login
Password Hashing: bcrypt with 12 rounds
Token Type: JWT with 24-hour expiration
Refresh Tokens: 7-day expiration, stored in HttpOnly cookies

2. Single Sign-On (SSO)

Supported Providers:

Provider	Protocol	Configuration
Google	OAuth2	Set `OAUTH2_CLIENT_ID` and `OAUTH2_CLIENT_SECRET`
Microsoft	OAuth2	Configure Azure AD application
Okta	SAML 2.0	Set `SAML_ENTITY_ID` and `SAML_IDP_METADATA_URL`
Generic SAML	SAML 2.0	Custom IdP metadata URL

SSO Endpoints:

Google: GET /api/sso/google
Microsoft: GET /api/sso/microsoft
Okta: GET /api/sso/okta
SAML: POST /api/sso/saml

Configuration Example:

# backend/auth-service/src/main/resources/application.yml
spring:
  security:
    oauth2:
      client:
        registration:
          google:
            client-id: ${OAUTH2_CLIENT_ID}
            client-secret: ${OAUTH2_CLIENT_SECRET}
            scope: profile,email
          microsoft:
            client-id: ${MS_CLIENT_ID}
            client-secret: ${MS_CLIENT_SECRET}
            scope: openid,profile,email

3. Multi-Factor Authentication (MFA)

Supported MFA Methods:

Method	Description	Setup Endpoint
TOTP	Time-based One-Time Password (Google Authenticator, Authy)	POST `/api/mfa/setup/totp`
SMS	SMS verification code	POST `/api/mfa/setup/sms`
Email	Email verification code	POST `/api/mfa/setup/email`
Backup Codes	One-time use backup codes	GET `/api/mfa/backup-codes`

MFA Setup Flow:

Enable MFA: POST /api/mfa/enable
Setup TOTP: Scan QR code with authenticator app
Verify Setup: POST /api/mfa/verify with first code
Generate Backup Codes: GET /api/mfa/backup-codes
Login with MFA: POST /api/auth/login → POST /api/mfa/verify

MFA Configuration:

# .env
MFA_ISSUER=FoodSecurityNet
MFA_ENABLED=true

# Email for MFA codes
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_USER=your-email@example.com
SMTP_PASSWORD=your-email-password

User Roles

FoodSecurityNet implements role-based access control (RBAC) with four roles:

Role	Description	Permissions
USER	Standard farmer/researcher	View data, upload own data, generate visualizations, use LLM
MODERATOR	Community leader/NGO worker	All USER permissions + moderate collaboration sessions, review user submissions
ADMIN	System administrator	All MODERATOR permissions + manage users, configure system settings, access audit logs
ENTERPRISE	Enterprise client	All ADMIN permissions + SSO configuration, custom branding, advanced analytics

Role Assignment:

# Assign role via API (Admin only)
curl -X PUT http://localhost:8081/api/users/123/role \
  -H "Authorization: Bearer ADMIN_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"role": "MODERATOR"}'

JWT Token Structure

{
  "sub": "user@example.com",
  "userId": "123",
  "roles": ["USER", "MODERATOR"],
  "mbtiType": "ENTJ",
  "iat": 1640000000,
  "exp": 1640086400
}

Security Best Practices

HTTPS Only: All authentication endpoints require HTTPS in production
Token Storage: Store JWT in memory or secure HttpOnly cookies, never localStorage
Token Refresh: Refresh tokens before expiration to avoid session disruption
Password Policy: Minimum 8 characters, uppercase, lowercase, number, special character
Rate Limiting: 5 failed login attempts → 15-minute lockout
Audit Logging: All authentication events logged for security monitoring

FoodSecurityNet provides a unique personalization layer based on the Myers-Briggs Type Indicator (MBTI), tailoring the user experience to 16 personality types.

The 16 MBTI Types

Type	Name	Characteristics
ENTJ	The Commander	Strategic, leadership-focused, results-driven
INTJ	The Mastermind	Analytical, strategic, long-term planning
ENTP	The Debater	Innovative, exploratory, idea-driven
INTP	The Thinker	Logical, detail-oriented, problem-solving
INFJ	The Advocate	Intuitive, empathetic, holistic
INFP	The Mediator	Creative, value-driven, narrative-focused
ENFJ	The Protagonist	Inspirational, visionary, community-focused
ENFP	The Campaigner	Enthusiastic, creative, people-oriented
ISTJ	The Logistician	Structured, organized, rule-based
ISFJ	The Defender	Supportive, practical, nurturing
ESTJ	The Executive	Authoritative, task-oriented, organized
ESFJ	The Consul	Warm, community-focused, supportive
ISTP	The Virtuoso	Practical, hands-on, problem-solving
ISFP	The Adventurer	Creative, sensory-driven, flexible
ESTP	The Entrepreneur	Actionable, dynamic, fast-paced
ESFP	The Entertainer	Vibrant, engaging, energetic

How Personalization Works

1. UI Customization

ENTJ (The Commander):

Dashboard: Strategic metrics, crop yield forecasts, policy recommendations
Visualizations: Clean, professional 3D maps with performance metrics
Workflow: Fast, results-focused navigation with executive summaries

INFP (The Mediator):

Dashboard: Artistic, narrative-driven interfaces with storytelling elements
Visualizations: Colorful, creative 3D maps with aesthetic appeal
Workflow: Flexible, value-aligned workflows with inspirational prompts

ESTP (The Entrepreneur):

Dashboard: Dynamic, real-time updates with instant feedback
Visualizations: Interactive, fast-loading 3D maps
Workflow: Quick-action buttons, concise information, minimal clicks

2. LLM Response Styles

ENTJ Query: "What crops should I plant?"

Response: "Based on your region's climate and soil data, I recommend planting drought-resistant maize and sorghum. This strategy will maximize yield by 23% and reduce water usage by 30%. Implement within 2 weeks for optimal results."

INFJ Query: "How can I improve soil health?"

Response: "Nurturing your soil is about creating a sustainable ecosystem that honors the land. Consider incorporating organic compost and cover crops like clover, which will enrich nutrients naturally and support biodiversity. This holistic approach aligns with long-term environmental stewardship."

ESTP Query: "Quick farming tips!"

Response: "1. Plant maize now. 2. Use drip irrigation. 3. Apply fertilizer in 2 weeks. 4. Harvest in 90 days. Done!"

3. Collaboration Features

MBTI Type	Collaboration Style
ENTJ	Leadership tools, decision-making dashboards, strategy planning
INFJ	Empathy tools, conflict resolution, community harmony
ESTP	Fast-paced, live updates, action-oriented collaboration
ISTJ	Structured task lists, organized workflows, clear protocols

Setting Your MBTI Type

During Registration:

curl -X POST http://localhost:8081/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{
    "email": "user@example.com",
    "password": "SecurePassword123!",
    "mbtiType": "ENTJ"
  }'

Update Profile:

curl -X PUT http://localhost:8081/api/users/me \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "mbtiType": "INFP"
  }'

Example Personalization Scenarios

Scenario 1: Farming Recommendations

INTJ: "Detailed soil analysis shows nitrogen deficiency at 15ppm. Implement precision fertilization strategy with controlled-release urea at 120kg/ha. Expected yield increase: 18-22% over 120 days."

ESFJ: "Your community would benefit from planting beans together! This crop improves soil health and provides nutritious food for everyone. Let's coordinate with neighboring farms for a group harvest celebration."

Scenario 2: Troubleshooting

INTP: "Error trace: NullPointerException at line 247. Root cause: CSV header mismatch. Solution: Validate column names ['crop', 'yield', 'region'] against schema. Detailed logs attached."

ISFJ: "Don't worry, we can fix this together! It looks like your CSV file has a small formatting issue. Let's check the column names step-by-step. I'll guide you through it."

Security

Security Best Practices

1. OWASP Compliance

FoodSecurityNet follows OWASP Top 10 security guidelines:

Vulnerability	Mitigation
Injection	Parameterized queries, input validation, sanitization
Broken Authentication	JWT, MFA, password hashing (bcrypt), rate limiting
Sensitive Data Exposure	HTTPS/TLS, data encryption at rest (AES-256)
XML External Entities	Disable XML external entity processing
Broken Access Control	RBAC, JWT validation, permission checks
Security Misconfiguration	Secure defaults, regular updates, minimal privileges
Cross-Site Scripting (XSS)	Content Security Policy, sanitize-html, React auto-escaping
Insecure Deserialization	Validate serialized data, avoid untrusted sources
Using Components with Known Vulnerabilities	Dependency scanning, automated updates
Insufficient Logging & Monitoring	Structured logging, audit trails, alerting

2. Data Encryption

In Transit:

TLS 1.3 for all HTTPS connections
WebSocket Secure (WSS) for real-time communication
Certificate pinning for mobile apps

At Rest:

AES-256 encryption for database fields (PII, passwords)
Encrypted backups
Key rotation every 90 days

Implementation:

// Spring Security TLS configuration
@Configuration
public class SecurityConfig {
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .requiresChannel()
            .anyRequest()
            .requiresSecure(); // Force HTTPS
        return http.build();
    }
}

3. Rate Limiting
