DDAS: A Lightweight Hash-Based Framework for Real-Time Duplicate Detection in Multi-Tenant Web Applications
Abstract
As the need for storage grows in multi-tenant web apps, redundant data ingestion is still a major problem. This paper presents the Data Download Duplicate Alert System (DDAS), a streamlined framework designed to alleviate storage inefficiencies via real-time duplicate detection. DDAS uses SHA-256 cryptographic hashing in a Flask-based backend to make unique digital signatures for each file that comes in. Before allocating storage, these hashes are checked against a central MySQL relational database. The results of the experiment show that DDAS works well to get rid of unnecessary uploads while keeping latency to a minimum. This study offers a scalable, low-overhead way to improve data integrity and make better use of storage in distributed environments.

Suraksha Setu: AI-Driven Criminal Identification Using Facial Recognition Technology with Aadhaar Integration for Scalable Intelligent Public Safety in Urban India
Suraksha Setu is an AI-powered dual-platform public safety ecosystem designed to address the critical operational gaps in Indian law enforcement. The system integrates Facial Recognition Technology (FRT) using the DeepFace framework (VGGFace2 backbone), real-time multi-class object detection via YOLOv8 fine-tuned on a 14,200-image custom dataset, and biometric identity verification through the UIDAI Aadhaar Authentication API 2.5. The architecture comprises two primary subsystems: (1) a Citizen Safety Portal providing geofence-triggered crime alerts via Firebase Cloud Messaging, SOS GPS triangulation, and a community gamification layer; and (2) a Police Operational Dashboard delivering live AI-monitored CCTV analytics, LIDAR/UGS-based restricted-zone intrusion detection, crime heatmap visualization via MongoDB GeoJSON, and centralized Aadhaar-linked offender database access. Comprehensive evaluation demonstrates that DeepFace achieves 94.8% facial recognition accuracy under operational CCTV conditions, surpassing FaceNet (91.7%) and ArcFace (89.3%). YOLOv8 attains a mean Average Precision (mAP@0.5) of 91.3% across five threat categories, with weapon detection reaching 92.1% F1-score. System response latency averages 1.2 seconds for SOS dispatch and 2.8 seconds for FRT matching — a 75–80% reduction over conventional systems. An ablation study confirms that each architectural component contributes measurably to system performance. A security assessment across seven threat vectors demonstrates compliance with NIST SP 800-175B, UIDAI regulations, and OWASP Top-10 standards. Suraksha Setu represents a replicable, nationally scalable framework for AI-integrated, constitutionally compliant smart policing
