Digital Forensics Importance Of Hash Values
...Computer science Hash Values in Digital Forensics
Introduction
Hash values denote condensed representations of digitized or binary content within digital material; however, they offer no additional information pertaining to the contents of any material interpretable by an individual. Moreover, the hash function is algorithms that convert variable-sized text quantities into hash values (which are fixed-sized outputs). Also called “cryptographic hash functions,” they facilitate the development of digital signatures, short textual condensations, and hash tables for the purpose of analysis (Fang et al., 2011; Kumar et al., 2012). In this paper, hash functions and their significance will be addressed.
Description
H (hash function) represents a transformation taking variable-sized input „m? and returning fixed-sized strings (h or hash value; i.e., h = H (m)) (Kumar et al., 2012). The hash functions possessing only the above property can be put to various broad computational uses; however, when applied to cryptography, they normally possess a few……

US Customs And Border Protection And Defense Intelligence Agency
...Computer science Private Security and Homeland Defense
Questions 2 and 3
Question 2:
The Intelligence Community is comprised of 17 agencies. These agencies work with Federal, State, Local, Tribal and Territorial partners to protect the homeland. Four of these agencies are intelligence elements of the Department of Defense Services – Army, Navy, Marine Corps and Air Force. Please pick ONE of these Department of Defense Services intelligence elements and explain its mission. In what ways does it contribute to the intelligence cycle? Provide examples.
The Department of Defense Services intelligence element that I selected in this particular case is the Defense Intelligence Agency (DIA). The stated mission of DIA is “provide intelligence on foreign militaries to prevent and decisively win wars” (DIA, 2020). Thus, it is important to note, from the onset, that this particular agency largely concerns itself with not only the gathering, but also the production of military intelligence. As……

Fake News Detection
...Computer science Fake News Detection
Introduction
How can fake news be detected and prevented from dominating the online discourse of news events? Numerous researchers have been discussing this issue and identifying ways to detect fake news, whether on social media (Shu et al.) or by creating a benchmark dataset to facilitate the process (Wang). The topic of this study is fake news detection and what methods are available in this new field. The reason for addressing this topic is that fake news has been a hot button issue in politics ever since the election of Donald Trump. Understanding how fake new proliferates and what can be done to stop its proliferation is something that the digital community can benefit from. The inquiry question for this review is: What are some of the ways that fake news detection can be facilitated?
Body
This literature is organized according to what the researchers have found.……
