Prototyped a secure decentralized EHR(Electronic health record) Audit System using Hyperledger Fabric(audit data stored on a shared public ledger) and a Node.js application(web-browser based UI). Users(patients or auditors) can query audit data, view the raw encrypted ledger and perform an immutablility test on the audit data. System implements privacy, identification and authorization using appropriate cryptographic constructions.

[Research Paper] written in lieu of final project for CSCI530 Security Systems under the guidance of Prof Clifford Neuman. The paper analyzes and compares the performance and caveats of five different kernel-level rootkit detection mechanisms.

Created an app which lets users search for restaurants and businesses, look at detailed information (like reviews, location on map, operational hours, open/closed status, generic business details, pictures etc.) about them, share reviews on Twitter and FB, schedule reservations, review and/or cancel the reservations if needed. App has a Node.js backend hosted on Google Cloud Platform which uses the Yelp API suite for business search and search query autocompletion functionalities, the IPInfo geolocation API for auto-detecting the user's location and the Google Maps' geocoding API.

Given the source and binary release of a skeletal operating system called Weenix(developed as a teaching tool by Brown University), added in the missing functionalities for Processes & Threads, Virtual File System Layer and virtual memory.

Simulated a time-driven token bucket filter setup for streamlining incoming data packets. System included a packet arrival facility, a token bucket and the transmission facility(2 server entities). Mechanism ran in either of deterministic(uniform control parameters for all packets) or trace-driven mode(non-uniform control parameters provided in trace specification file) with provision for SIGINT interrupt handling for a graceful finish.

App to alert drivers of blackspots(accident prone areas) on highways based on tracked GPS location and data stored on Google Firebase. Alerts sent when nearing,entering and on exiting blackspot radius. User can also review marked blackspots on map. Dataset acquired from NHAI (Tamil Nadu blackspot data).
