Overview
PROTECTING DIGITAL WORKSPACES IN REAL TIMEKhetak serves as a real-time browser guardian designed during a high-stakes cybersecurity hackathon. Its core purpose is to filter out NSFW or adult content on popular feeds like Instagram and Twitter via intent-aware AI models. It also contains a 'One-Click Report' dashboard linked directly to cybersecurity portals, giving users immediate pathways to flag malware, phishing, and online harassment.
The Problem
Workspaces and children are exposed to inappropriate visual content and cyberthreats on modern social feeds. Building a low-latency browser plugin that blurs adult content client-side without degrading browser speed or violating user privacy presents a complex local processing challenge.
My Solution
We engineered Khetak using TensorFlow.js for local browser execution and WebExtensions APIs. Image streams are analyzed client-side via optimized neural nets. When mature content is identified, custom CSS filters are applied to blur the parent node in real-time. Phishing threats are checked using local FastAPI database logs.
Impact & Results
Measurable outcomes that drive business growth and user engagement.
