The 3S Spatial Awareness Assessment is a privacy-first cognitive testing platform designed to digitize and enhance spatial neglect assessments. Leveraging secure encryption and adaptive machine learning models, it enables continuous, real-world cognitive monitoring without compromising user data privacy. Inspired by validated clinical research, the system provides a scalable, secure foundation for future cognitive health applications.

• Privacy-Preserving Data Collection: End-to-end encrypted cognitive test results.
• Adaptive AI Model: Continuously improves accuracy as more tests are performed.
• Secure Real-Time Updates: User data remains protected while enhancing model performance.
• Web-Based Platform: Lightweight, accessible system for both practitioners and researchers.

• Python: Backend development, data processing.
• Flask: Server-side web application framework.
• PyTorch: Machine learning model development.
• TenSEAL: Encrypted computations using CKKS scheme.
• HTML/CSS/JavaScript/Jinja: Frontend interface.

• Encrypted Model Training: Architected a workflow that allows efficient model updates while data remains encrypted, solving major performance and scalability hurdles.
• CKKS Computation Overhead: Tuned system resources and workflows to support CKKS homomorphic encryption without major latency penalties.
• End-to-End Security: Designed middleware that guarantees encryption persistence across all data handling stages.

• Award Winner: Earned Best Security Hack, sponsored by Nord Security, at HackRU Fall 2024.
• Functional End-to-End Prototype: Achieved encrypted cognitive assessment and adaptive model learning on real data inputs.
• Security-First Design: Successfully demonstrated privacy-preserving machine learning workflows.

The 3S Spatial Awareness Assessment is a research prototype. To run it:

1. Clone the repository and install dependencies:

   git clone https://github.com/VictorJimenez3/threesAssessmentDigitized.git
   cd threesAssessmentDigitized
   pip install -r requirements.txt
   

2. Launch the server:

   python app.py
   

3. Access the assessment tool through your browser at http://localhost:5000.

Note: For demonstration and academic use only. Production deployment would require formal clinical review.
