IntroductionIn recent decades, enormous technological advances have revolutionized the way intelligence and information are collected, processed, used and disseminated. According to Curry et al. (2013), organizations grapple with the challenge of processing and analyzing huge volumes of highly dynamic data. The same challenge continues to face our intelligence apparatus and those charged with the responsibility of protecting citizens from internal and external threats (Cogan, 2004). Importantly, the new role of Big Data emerges at a time when increasingly complex adversaries are emerging and the compelling power of globalization continues to eliminate national boundaries (Curry et al., 2013). A universally accepted definition of the word The term "intelligence" has not yet been adopted. However, a common element of intelligence operations, as most conventional definitions of the phenomenon show, is secrecy (Dupont, 2005; Cogan, 2004; Scott and Jackson, 2004). However, thanks to technological advances, it is now possible to access information from sources that the intelligence community considers open (Rolington, 2013). As we will see later, this has its own advantages and disadvantages. Some contemporary definitions strongly emphasize that the traditional concept of secrecy becomes less and less useful as the need for information sharing becomes imperative for intelligence operations (Scott & Jackson, 2004; Cogan, 2004; Warner, n/d ). On the other hand, some argue that as long as it is open, it cannot be secret (Lowenthal, 2009). Certainly, big data holds great promise for intelligence, but whether or not the boundary between intelligence and information is disappearing is a two-sided question...... middle of paper ...... there is . Traditionally, secrecy is the building block of intelligence. Proponents argue that secrecy is important to intelligence operations because of the need to protect the sources from which it is obtained and the need to avoid premature judgments. However, critics have largely questioned the validity of the definition of intelligence from this perspective and its applicability today. Some fear that such a description limits the understanding of the boundary between intelligence and information. With the multiplicity of information sources in the Internet age, open source intelligence has become more important than ever, despite the intelligence community's widespread reluctance to recognize it. Whether the boundary between intelligence and information has collapsed under the weight of big data is a two-dimensional question..
