Characteristics analysis for the cyberlockers files study on Rapidgator Speedyshare and 1Fichier

摘要

As the bandwidth of Internet rises from ISPs, the proportion of different Internet traffic and underling services have changed. There is about 20% decrease of the P2P traffic compared to an increase of more than 10% of the traffic of cyberlockers services, which are websites providing direct file download functionalities. In this paper we present a recent study over three cyberlockers: Rapidgator, Speedyshare and 1Fichier. Compared to prior studies, we applied a bias-free sampling method to randomly gather hosted files on the three cyberlockers. We aim at figuring out the characteristics of the hosted files on cyberlockers. In our work, we analysed and estimated the total number of files and the total size of files on these three cyberlockers. We specifically discussed the file size and file number distribution of hosted files in different file format and file content. Our results show that split-compressed files take a large part of the volume; there are many raw files on cyberlockers. Additionally, the results point that Rapidgator and 1Fichier are used to host entertainment and professional files while Speedyshare is mainly used to host private files.
