SKYNET (surveillance Program)
SKYNET is a program by the U.S. National Security Agency that performs machine learning analysis on communications data to extract information about possible terror suspects. The tool is used to identify targets, such as al-Qaeda couriers, who move between GSM cellular networks. Specifically, mobile usage patterns such as swapping SIM cards within phones that have the same ESN, MEID or IMEI number are deemed indicative of covert activities. Like many other security programs, the SKYNET program uses graphs that consist of a set of nodes and edges to visually represent social networks. The tool also uses classification techniques like random forest analysis. Because the data set includes a very large proportion of true negatives and a small training set, there is a risk of overfitting. Bruce Schneier argues that a false positive rate of 0.008% would be low for commercial applications where "if Google makes a mistake, people see an ad for a car they don't want to buy" but "if ...

National Security Agency
The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for foreign and domestic intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The existence of the NSA was not revealed until 1975. The NSA has roughly 32,000 employees. Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Between then and the end of the Cold War, it became the largest of the U.S. intelligence organizations in terms of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Positive Rate
In statistics, when performing multiple comparisons, a false positive ratio (also known as fall-out or false alarm ratio) is the probability of falsely rejecting the null hypothesis for a particular test. The false positive rate is calculated as the ratio between the number of negative events wrongly categorized as positive (false positives) and the total number of actual negative events (regardless of classification). The false positive rate (or "false alarm rate") usually refers to the expectancy of the false positive ratio. Definition The false positive rate is FPR=\frac where \mathrm is the number of false positives, \mathrm is the number of true negatives and N=\mathrm+\mathrm is the total number of ground truth negatives. The level of significance that is used to test each hypothesis is set based on the form of inference ( simultaneous inference vs. selective inference) and its supporting criteria (for example FWER or FDR), that were pre-determined by the researche ...

Drone Warfare
Drone warfare is a form of aerial warfare using unmanned combat aerial vehicles (UCAV) or weaponized commercial unmanned aerial vehicles (UAV). The United States, United Kingdom, Israel, China, South Korea, Iran, Italy, France, India, Pakistan, Russia, Turkey, and Poland are known to have manufactured operational UCAVs as of 2019. As of 2022, the Ukrainian enterprise Ukroboronprom and NGO group Aerorozvidka have built strike-capable drones and used them in combat. Drone attacks can be conducted by commercial UCAVs dropping bombs, firing a missile, or crashing into a target. Since the turn of the century, most drone strikes have been carried out by the US military in such countries as Afghanistan, Pakistan, Syria, Iraq, Somalia and Yemen using air-to-surface missiles, but drone warfare has increasingly been deployed by Russia, Ukraine, Turkey, Azerbaijan and by militant groups such as the Houthis. Drones strikes are used for targeted killings by several countries. In 202 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intelligence Agency Programmes Revealed By Edward Snowden
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context. Intelligence is most often studied in humans but has also been observed in both non-human animals and in plants despite controversy as to whether some of these forms of life exhibit intelligence. Intelligence in computers or other machines is called artificial intelligence. Etymology The word ''intelligence'' derives from the Latin nouns '' intelligentia'' or '' intellēctus'', which in turn stem from the verb '' intelligere'', to comprehend or perceive. In the Middle Ages, the word ''intellectus'' became the scholarly technical term for understanding, and a translation f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Intercept
''The Intercept'' is an American left-wing news website founded by Glenn Greenwald, Jeremy Scahill, Laura Poitras and funded by billionaire eBay co-founder Pierre Omidyar. Its current editor is Betsy Reed. The publication initially reported on documents released by Edward Snowden and was considered to be "activist voice for privacy and civil liberties". Co-founders Greenwald and Poitras subsequently left amid public disagreements about the leadership and direction of the organization. In recent years, the website's editorial stance has become more closely aligned with the hard-left of the Democratic Party. It was among the first to report on the campaign of Alexandria Ocasio-Cortez, and often criticizes moderate democrats from a left-wing perspective. Its editorial policy explicitly rejects "mandating balance" when covering stories. ''The Intercept'' has published in English since its founding, and in Portuguese since the 2016 launch of the Brazilian edition staffed b ...

Global Surveillance
Global mass surveillance can be defined as the mass surveillance of entire populations across national borders. Its existence was not widely acknowledged by governments and the mainstream media until the global surveillance disclosures by Edward Snowden triggered a debate about the right to privacy in the Digital Age. Its roots can be traced back to the middle of the 20th century when the UKUSA Agreement was jointly enacted by the United Kingdom and the United States, which later expanded to Canada, Australia, and New Zealand to create the present Five Eyes alliance. The alliance developed cooperation arrangements with several "third-party" nations. Eventually, this resulted in the establishment of a global surveillance network, code-named "ECHELON" (1971). Historical background The origins of global surveillance can be traced back to the late 1940s after the UKUSA Agreement was collaboratively enacted by the United Kingdom and the United States, which eventually culmina ...

Muslim Brotherhood
The Society of the Muslim Brothers ( ar, جماعة الإخوان المسلمين'' ''), better known as the Muslim Brotherhood ( '), is a transnational Sunni Islamist organization founded in Egypt by Islamic studies, Islamic scholar and schoolteacher Hassan al-Banna in 1928. Al-Banna's teachings spread far beyond Egypt, influencing today various Islamist movements from charitable organizations to political parties—not all using the same name. Initially, as a Pan-Islamism, Pan-Islamic, religious, and social movement, it preached Islam in Egypt, taught the illiterate, and set up hospitals and business enterprises. It later advanced into the political arena, aiming to end British colonial control of Egypt. The movement's self-stated aim is the establishment of a state ruled by Sharia law–its most famous slogan worldwide being: "Islam is the solution". Charity is a major aspect of its work. The group spread to other Muslim countries but has its largest, or one of its largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahmad Zaidan
Ahmad ( ar, أحمد, ʾAḥmad) is an Arabic male given name common in most parts of the Muslim world. Other spellings of the name include Ahmed and Ahmet. Etymology The word derives from the root (ḥ-m-d), from the Arabic (), from the verb (''ḥameda'', "to thank or to praise"), non-past participle (). Lexicology As an Arabic name, it has its origins in a Quranic prophecy attributed to Jesus in the Quran which most Islamic scholars concede is about Muhammad. It also shares the same roots as Mahmud, Muhammad and Hamed. In its transliteration, the name has one of the highest number of spelling variations in the world. Though Islamic scholars attribute the name Ahmed to Muhammed, the verse itself is about a Messenger named Ahmed, whilst Muhammed was a Messenger-Prophet. Some Islamic traditions view the name Ahmad as another given name of Muhammad at birth by his mother, considered by Muslims to be the more esoteric name of Muhammad and central to understanding his n ...

Islamabad
Islamabad (; ur, , ) is the capital city of Pakistan. It is the country's ninth-most populous city, with a population of over 1.2 million people, and is federally administered by the Pakistani government as part of the Islamabad Capital Territory. Built as a planned city in the 1960s, it replaced Rawalpindi as Pakistan's national capital. The city is notable for its high standards of living, safety, cleanliness, and abundant greenery. Greek architect Constantinos Apostolou Doxiadis developed Islamabad's master plan, in which he divided it into eight zones; administrative, diplomatic enclave, residential areas, educational and industrial sectors, commercial areas, as well as rural and green areas administered by the Islamabad Metropolitan Corporation with support from the Capital Development Authority. Islamabad is known for the presence of several parks and forests, including the Margalla Hills National Park and the Shakarparian. It is home to several landmarks, inc ...
