Exploring Cyberlockers Content

Abstract

As the bandwidth of Internet rises by ISPs, the proportion of different Internet traffics and underlying used service has changed. There is about 20% decrease of the P2P traffic compared to an increase of more than 10% of the traffic of direct file sharing service through cyberlockers. In this paper we present a recent study over four cyberlockers: Rapidgator, Speedyshare, 1Fichier and Megashares. Compared to prior studies, we apply a bias-free sampling method to randomly gather hosted files on the four cyberlockers. We aim at giving a statistic study to find out the characteristics of the hosted files on cyberlockers. In our work, we analyse and estimate the total number of files and the total size of files on the four cyberlockers. We specifically discuss the size and number distributions of hosted files in file format and file content classifications. Our results show that different cyberlockers have different number and size distributions, but on most cyberlockers split- compressed files and uncompressed files take a relative large part of the volume. Additionally, the content classification analyse results show that users on different cyberlockers have different usage preferences. Rapidgator inclines to entertainment usage; Speedyshare and 1Ficher incline to personal and entertainment usage; Megashares inclines to entertainment and professional usage. And most of them like to upload series files.
