Data Security

Comprehensive guide to DEEPS security features, privacy protection, and regulatory compliance for educational institutions.

Security Architecture

Privacy-First Design

DEEPS is architected with student privacy as the foundation:

Local-Only Processing: 

🏛️ Your Institution
├── 🖥️ DEEPS Application (Local)
├── 🗄️ Student Database (Local)
├── 📁 Backup Files (Local/Network)
└── 🌐 Internet Connection
    └── ✅ License Verification Only
    └── ❌ No Student Data Transmission

Zero External Data Sharing: - All student records remain within your institutional boundaries - No cloud dependencies for core functionality - Complete offline operation after initial setup - Full institutional control over all data

Compliance Standards

Educational Privacy Regulations:

Family Educational Rights and Privacy Act: - Student consent required for data sharing - Directory information protections - Access logging and audit trails - Secure data handling procedures

General Data Protection Regulation: - Data minimization principles - Right to erasure (right to be forgotten) - Data portability requirements - Breach notification procedures

Country-Specific Requirements: - Adaptable to national privacy laws - Configurable data retention policies - Customizable consent mechanisms - Local audit and reporting support

Access Control

User Authentication

Multi-Layer Security:

  1. Primary Authentication 

    Username: academic.staff@university.edu
Password: [Strong password requirements]

Password Requirements:
• Minimum 8 characters
• Mix of upper/lowercase letters
• Numbers and special characters
• Regular password updates

  2. Session Management

  3. Automatic session timeout
  4. Concurrent session limits
  5. Activity-based session renewal

  6. Secure session token handling

  7. Account Security

  8. Failed login attempt monitoring
  9. Account lockout protection
  10. Password recovery procedures
  11. Security question backup
