  • Data Source Diversity in Identifying and Understanding Events
    BABEL BEACON WORLDWIDE: DATA SOURCE DIVERSITY IN IDENTIFYING AND UNDERSTANDING EVENTS Introduction: As the online data landscape continues to exponentially expand, analysts are increasingly challenged to find where key pieces of information are hiding. Because actionable data can be found anywhere online, it is essential to cast the widest possible net over the vast pool of data sources – globally. It is our observation that many analysts, when analyzing publicly available information (PAI), tend to focus on just a few large social media (SM) platforms like Facebook, Instagram, and/or Twitter. Indeed, these data sources are useful for situational awareness in certain areas around the world. But they, in context, comprise only a small portion of the immense available data within the data universe. So, the appropriate question is: “What other data sources are there, relative to my question, that should be queried?” This Beacon explores the importance of leveraging the variety of global data sets by diving into historical social media posts and analyzing conversations they spawned both within and beyond the original posting site. Babel Street analysts winnowed down data from thousands of social media outlets, blogs and message boards, global news outlets, and the dark web to identify where else these posts were being referenced and by whom, in order to pinpoint relevant and potentially actionable intelligence. BLUF: o Focusing PAI research on only a few large SM platforms severely limits the information analysts can derive about ongoing

  • Why Are Some Websites Researched More Than Others? a Review of Research Into the Global Top Twenty Mike Thelwall
    Why are some websites researched more than others? A review of research into the global top twenty Mike Thelwall How to cite this article: Thelwall, Mike (2020). “Why are some websites researched more than others? A review of research into the global top twenty”. El profesional de la información, v. 29, n. 1, e290101. https://doi.org/10.3145/epi.2020.ene.01 Manuscript received on 28th September 2019 Accepted on 15th October 2019 Mike Thelwall * https://orcid.org/0000-0001-6065-205X University of Wolverhampton, Statistical Cybermetrics Research Group Wulfruna Street Wolverhampton WV1 1LY, UK [email protected] Abstract The web is central to the work and social lives of a substantial fraction of the world’s population, but the role of popular websites may not always be subject to academic scrutiny. This is a concern if social scientists are unable to understand an aspect of users’ daily lives because one or more major websites have been ignored. To test whether popular websites may be ignored in academia, this article assesses the volume and citation impact of research mentioning any of twenty major websites. The results are consistent with the user geographic base affecting research interest and citation impact. In addition, site affordances that are useful for research also influence academic interest. Because of the latter factor, however, it is not possible to estimate the extent of academic knowledge about a site from the number of publications that mention it. Nevertheless, the virtual absence of international research about some globally important Chinese and Russian websites is a serious limitation for those seeking to understand reasons for their web success, the markets they serve or the users that spend time on them.

All files related to privacy are popular instant messaging (IM) in China. We have managed encrypted and not readable without a successful login. to acquire the contact list, the QQ account, the chats Even if we are able to acquire these files, it takes great records, the QQ discussion group, the display names and the efforts to parse them. However, we can collect sensitive contents of network notepad. They are of great interest to the examiners. Besides, as the techniques we use to search information from the physical memory. The QQ client for process are able to reveal terminated and hidden would decrypt all received messages. Therefore, the processes, we are very likely to find sensitive information as physical memory would contain the plaintext of these long as somebody has logged in the QQ client. What’s more, messages. we propose the method of reconstructing the process space Thus it can be seen that the forensics for the QQ client by integrating paging file into memory dump file.

  • On the Existence of Subliminal Channel in Instant Messaging Systems
    International Journal of Security and Its Applications Vol. 9, No. 3 (2015), pp. 353-362 http://dx.doi.org/10.14257/ijsia.2015.9.3.27 On the Existence of Subliminal Channel in Instant Messaging Systems Lingyun Xiang1, Yuhua Xie2, Gang Luo3 and Weizheng Wang1 1School of Computer and Communication Engineering, Changsha University of Science and Technology, Changsha 410114, China 2Loudi Municipal Office, SAT, Loudi 417000, China 3College of Information Science and Engineering, Hunan University, Changsha 410082, China [email protected], [email protected], [email protected] Abstract Subliminal channel is a covert communication channel that can securely exchange secret information. By analyzing the communication protocols and encryption algorithms of two popular instant messaging systems QQ and Skype, this paper devotes the efforts to find whether they satisfy the condition of establishing subliminal channel or not. The broad-band subliminal channel can be established in Skype and QQ messages. Therefore, two subliminal channel schemes are proposed to embed and extract subliminal information. Finally, performances of the proposed subliminal channels are compared with those of the ones based on ElGamal digital signature and Newton channel. Experimental results and theoretical analysis show that they are easy to be implemented with large bandwidth and execute fast. Keywords: subliminal channel, covert communication, instant messaging, Skype, QQ 1. Introduction Subliminal channel is a covert communication channel constructed in public channel. It hides additional message mainly in public-key cryptosystem, authentication, and digital signature schemes. The sender and the designated receiver can transmit secret information by the subliminal channel without arousing suspicion from the public or channel warden.
