2012 Proceedings of the 28th Annual Computer Security Applications Conference on - ACSAC '12  
We do so by designing and implementing Twitsper, a wrapper around Twitter that enables private group communication among existing Twitter users while preserving Twitter's commercial interests.  ...  Specifically, we demonstrate that such a privacy control can be offered to users of Twitter today without having to wait for Twitter to make changes to its system.  ...  We then send a message from each of the clients and refresh the home screen; there was at least one update to the home screen.  ...

Online Social Networks: Threats and Solutions

Michael Fire, Roy Goldschmidt, Yuval Elovici
2014 IEEE Communications Surveys and Tutorials  
We also offer simple-to-implement recommendations for OSN users which can improve their security and privacy when using these platforms. Furthermore, we suggest future research directions.  ...  According to recent studies, OSN users readily expose personal and private details about themselves, such as relationship status, date of birth, school name, email address, phone number, and even home  ...  Additional possible future research directions include developing privacy-preserving OSNs, such as Safebook [155] , and developing solutions for privacy-preserving ad hoc social networks (i.e., self-configuring  ...

Social media data archives in an API-driven world

Amelia Acker, Adam Kreisberg
2019 Archival Science  
In this article, we explore the long-term preservation implications of application programming interfaces (APIs) which govern access to data extracted from social media platforms.  ...  We then define a range of possible types of API users motivated to access social media data from platforms and consider how these users relate to principles of digital preservation.  ...  While this system is still in development, its organizational home within one of the oldest research data repositories in the world signals that the social science research community is reckoning with  ...
