I. Introduction
It is hard to imagine life without online accounts, for instance, webmail accounts for business and personal communication, e-commerce accounts for online shopping, and cloud storage accounts for convenient document storage and sharing. As of 2014, 21% of EU citizens relied on cloud accounts to store their documents. This shows the widespread utility and adoption of cloud storage platforms. However, there are downsides to the use of cloud accounts. Like most online accounts, cloud accounts often accumulate sensitive information over time, for instance, financial and personal secrets. This makes them attractive targets to cybercriminals seeking to steal and monetize such information [12].
