Cloud vs Local: Better Data Storage Device Mengxuan Chen Edward Liu 1 1

Audience In the new information technology era, universities offer students digital files over hard copies Students need a secure, yet easy to use way to store such digital files This investigation is aiming to solve this problem - The audience of this investigation would be university students 2 2

Problem Compare cloud data storage services and local data storage devices to determine: What is the balance of security and usability for data storage devices? What is the ideal data storage device which satisfies both security and usability criteria for the university students? 3 3

Why is this important? Students need a good way to store study notes and material If data is lost, students will have to waste time to recomplete assignments It is difficult for students to choose between cloud and local data storage. We help students decide by exploring the balance between usability and security between these two storage mediums 4 4
