The Corsarius

These are the three major projects I worked for during my undergraduate years in the UP Diliman Department of Computer Science. I typeset and documented the full papers to which these abstracts belong in LaTeX / MikTeX. (It gives me some sort of geeky pride that I know my way around the typesetting tool, hehe.)

Thesis (CS 198/199)

The Highly Secure Adaptive Mobile Multimedia Streaming Service (HAMSTER) provides highly secure streaming, sharing, and management of video clips taken using a mobile device. This is accomplished by implementing robust security algorithms in devices with limited computing power and memory, without compromising performance or user satisfaction.

The advent of MMS-enabled devices has ushered in a multimedia revolution. We are seeing a shift from old services to the new ones that take advantage of the MMS devices’ power and flexibility. While SMS and voice services are still popular, multimedia (specifically video) services are quickly growing in importance and use. However, the management of these videos is laden with problems; mobile devices suffer from limited memory, present video sharing services can use improvement, and security is often an afterthought.

HAMSTER addresses these problems by providing users with video albums that they can access anytime, anywhere through a mobile device application and a web application. These albums, along with almost every action within the service, are strongly protected by the HAMSTER cryptosystem.


*HAMSTER (along with its sister thesis project MOVISS) was ‘branded’ as Sinfinity for the Philippine Emerging Startups Open Challenge and the 1st UPD College of Engineering Marketing Competition. View the HAMSTER thesis poster.

CHESTER, or Curriculum Handling Engine and Student Evaluator, is a web-based application designed to be a one-stop course management information system for the Department of Computer Science of UP Diliman. The system automates the management of the Department’s various curricula, grade submission, enlistment pre-advising, and tracking of the students’ progress in course units taken.

CHESTER reduces the Department’s paper, printing, and manpower costs in carrying out the aforementioned tasks, especially in the determination of whether a student is eligible or not to enlist in a particular subject/s. While not a true subject enlistment engine, CHESTER provides an excellent complement to any such enlistment system by serving as a robust, dynamic, and all-in-one repository of a student’s applying curriculum, units taken, past grades, and other relevant information. CHESTER also provides an intuitive, graphical “flowchart” to represent the progress of a student in his course subjects and their respective grades.

CS 165: Database Systems

by Phillip Kimpo Jr, Adelaida Sophia Marie Lucero, Jonas Fabian Roque, and Maybelle Sibayan


At present, the constituents of the Department of Computer Science (DCS) of the University of the Philippines Diliman — both student and faculty alike — manually request and reserve resources such as LCD and overhead projectors, laptop computers, and rooms in the College of Engineering within DCS jurisdiction. Faculty members trying to obtain office supplies might find these resources to be lacking, and so they must make a verbal request regarding the deficiency to the authorities concerned. This process based on paper forms and mere spoken words is not by any means a paradigm of efficiency.

The Computer Science Online Resource Request and Reservation System (the CORRRS) is a web-based application designed to be a one-stop resource database system for the DCS. It seeks to automate the current resource reservation process employed by DCS students, faculty, and staff, thus alleviating the problems associated with manual paper-based systems.
