By exploiting flaws between the interplay of TCP and application-level protocols, ABTH was capable of quiety injecting TCP packets. In the case of Windows Live Messenger and its underlying protocol (Microsoft Notification Protocol), by using ABTH, an attacker was capable of impersonating anybody of his/her choosing and start a conversation with the victim. Read the paper for more details.

ABTH had its beginnings as a course project for EECE412 and would eventually be published in the Proceedings of EuroSec 2009. As an added bonus, we were invited to present our findings at the workshop in Nuremberg, Germany.

For my university capstone project, I designed and developered an activity monitoring system. The system utilizes FireFly sensor nodes that are placed on different parts of an individual's body to form a wireless sensor network. Data collected from this network is wireless transmitted to a processing client where the client will use various means of analysis to classify the user's motions under one of several categories: walking, sitting, running, standing, etc.

The RFID Library Management System was a project created for EECE375. In essence, we built a remote handheld device capable of reading RFID-tagged books where the handheld unit would communicate to base station via Zigbee. As pictures are typically worth a thousand words, here's a system block diagram.

When I became the webmaster for the UBC Badminton Club, I inherited a webpage that looked similar to this. As my eyes were beginning to bleed, I completely redesigned the webpage using Wordpress.

Every year, the UBC Badminton Club has a membership drive. As paper forms = chaos and online registration != chaos, I created an online registration system which resulted in app engine = awesome. Although you require the UBC Badminton credentials to login, the registration system is hosted at ubc-badminton.appspot.com/register.
