    An Empirical Study on Android for Saving Non-shared Data on Public Storage

    Get PDF
    With millions of apps that can be downloaded from official or third-party market, Android has become one of the most popular mobile platforms today. These apps help people in all kinds of ways and thus have access to lots of user's data that in general fall into three categories: sensitive data, data to be shared with other apps, and non-sensitive data not to be shared with others. For the first and second type of data, Android has provided very good storage models: an app's private sensitive data are saved to its private folder that can only be access by the app itself, and the data to be shared are saved to public storage (either the external SD card or the emulated SD card area on internal FLASH memory). But for the last type, i.e., an app's non-sensitive and non-shared data, there is a big problem in Android's current storage model which essentially encourages an app to save its non-sensitive data to shared public storage that can be accessed by other apps. At first glance, it seems no problem to do so, as those data are non-sensitive after all, but it implicitly assumes that app developers could correctly identify all sensitive data and prevent all possible information leakage from private-but-non-sensitive data. In this paper, we will demonstrate that this is an invalid assumption with a thorough survey on information leaks of those apps that had followed Android's recommended storage model for non-sensitive data. Our studies showed that highly sensitive information from billions of users can be easily hacked by exploiting the mentioned problematic storage model. Although our empirical studies are based on a limited set of apps, the identified problems are never isolated or accidental bugs of those apps being investigated. On the contrary, the problem is rooted from the vulnerable storage model recommended by Android. To mitigate the threat, we also propose a defense framework

    Millennials and the Increasing Use of Social Media: Impact on the Employee Life Cycle

    Full text link
    The millennial generation is a generation of society that values technology, media, and connections, all three being equally important. This paper studies and theorizes the implications that social media has had on the workplace throughout the employee life cycle and how the traditional processes of this cycle have been altered. In the workforce, this aspect of the employee life cycle incorporates all different stages an employee goes through. From networking to being hired, to forming connections with co-workers, to working hard and performing well, to being fired, social media has impacted each stage of this cycle. Social media is a phenomenon that has continuously grown and has become important in all aspects of society, but this paper argues that it has specifically influenced the work world. Popular social media platforms like LinkedIn and Facebook have encouraged employees to utilize social media to help aid in networking and personal connections but have also been used by employers to determine the organizations hiring and firing process. Social media use has only increased in recent years and it is evident that the implications discussed in this paper have made extremely beneficial changes to the employee life cycle

    Cloudworks: social networking for learning design

    Why do some social networking services work and others fail? Can we apply the best of Web 2.0 principles to an educational context? More specifically can we use this as a means of shifting teaching practice to a culture of sharing learning ideas and designs? Can we harness the potential of technologies to create more engaging learning experiences for students? These are the key questions this paper addresses. We describe how we are using the concept of 'object-orientated social networking' to underpin the creation of a social networking tool, Cloudworks, for sharing learning ideas and designs
