Surveillance is the monitoring of behavior, many activities, or information for the purpose of information gathering, influencing, managing or directing. This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic. It can also include simple technical methods, such as human intelligence gathering and postal interception.
Wiretapping, also known as wire tapping or telephone tapping, is the monitoring of telephone and Internet-based conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on an analog telephone or telegraph line. Legal wiretapping by a government agency is also called lawful interception. Passive wiretapping monitors or records the traffic, while active wiretapping alters or otherwise affects it.
Computer and network surveillance is the monitoring of computer activity and data stored locally on a computer or data being transferred over computer networks such as the Internet. This monitoring is often carried out covertly and may be completed by governments, corporations, criminal organizations, or individuals. It may or may not be legal and may or may not require authorization from a court or other independent government agencies. Computer and network surveillance programs are widespread today and almost all Internet traffic can be monitored.
A hidden camera or spy camera is a camera used to photograph or record subjects, often people, without their knowledge. The camera may be considered "hidden" because it is not visible to the subject being filmed, or is disguised as another object. Hidden cameras are often considered a surveillance tool.
A pen register, or dialed number recorder (DNR), is a device that records all numbers called from a particular telephone line. The term has come to include any device or program that performs similar functions to an original pen register, including programs monitoring Internet communications.
The Omnibus Crime Control and Safe Streets Act of 1968 was legislation passed by the Congress of the United States and signed into law by President Lyndon B. Johnson that established the Law Enforcement Assistance Administration (LEAA). Title III of the Act set rules for obtaining wiretap orders in the United States. The act was a major accomplishment of Johnson's war on crime.
The Electronic Communications Privacy Act of 1986 (ECPA) was enacted by the United States Congress to extend restrictions on government wire taps of telephone calls to include transmissions of electronic data by computer, added new provisions prohibiting access to stored electronic communications, i.e., the Stored Communications Act, and added so-called pen trap provisions that permit the tracing of telephone communications . ECPA was an amendment to Title III of the Omnibus Crime Control and Safe Streets Act of 1968, which was primarily designed to prevent unauthorized government access to private electronic communications. The ECPA has been amended by the Communications Assistance for Law Enforcement Act (CALEA) of 1994, the USA PATRIOT Act (2001), the USA PATRIOT reauthorization acts (2006), and the FISA Amendments Act (2008)
Katz v. United States, 389 U.S. 347 (1967), was a landmark decision of the U.S. Supreme Court in which the Court redefined what constitutes a "search" or "seizure" with regard to the protections of the Fourth Amendment to the U.S. Constitution. The ruling expanded the Fourth Amendment's protections from an individual's "persons, houses, papers, and effects", as specified in the Constitution's text, to include any areas where a person has a "reasonable expectation of privacy". The reasonable expectation of privacy standard, now known as the Katz test, was formulated in a concurring opinion by Justice John Marshall Harlan II.
The USA PATRIOT Act was passed by the United States Congress in 2001 as a response to the September 11, 2001 attacks. It has ten titles, each containing numerous sections. Title II: Enhanced Surveillance Procedures granted increased powers of surveillance to various government agencies and bodies. This title has 25 sections, with one of the sections containing a sunset clause which sets an expiration date, December 31, 2005, for most of the title's provisions. This was extended twice: on December 22, 2005 the sunset clause expiration date was extended to February 3, 2006 and on February 2 of the same year it was again extended, this time to March 10.
NSA warrantless surveillance — also commonly referred to as "warrantless-wiretapping" or "-wiretaps" — was the surveillance of persons within the United States, including U.S. citizens, during the collection of notionally foreign intelligence by the National Security Agency (NSA) as part of the Terrorist Surveillance Program. In late 2001, the NSA was authorized to monitor, without obtaining a FISA warrant, phone calls, Internet activities, text messages and other forms of communication involving any party believed by the NSA to be outside the U.S., even if the other end of the communication lays within the U.S.
The Terrorist Surveillance Program was an electronic surveillance program implemented by the National Security Agency (NSA) of the United States in the wake of the September 11, 2001 attacks. It was part of the President's Surveillance Program, which was in turn conducted under the overall umbrella of the War on Terrorism. The NSA, a signals intelligence agency, implemented the program to intercept al Qaeda communications overseas where at least one party is not a U.S. person. In 2005, The New York Times disclosed that technical glitches resulted in some of the intercepts including communications which were "purely domestic" in nature, igniting the NSA warrantless surveillance controversy. Later works, such as James Bamford's The Shadow Factory, described how the nature of the domestic surveillance was much, much more widespread than initially disclosed. In a 2011 New Yorker article, former NSA employee Bill Binney said that his colleagues told him that the NSA had begun storing billing and phone records from "everyone in the country."
Telephone call recording laws are legislation enacted in many jurisdictions, such as countries, states, provinces, that regulate the practice of telephone call recording. Call recording or monitoring is permitted or restricted with various levels of privacy protection, law enforcement requirements, anti-fraud measures, or individual party consent.

Telephone tapping in the Eastern Bloc was a widespread method of the mass surveillance of the population by the secret police.
The Digital Collection System Network (DCSNet) is the Federal Bureau of Investigation (FBI)'s point-and-click surveillance system that can perform instant wiretaps on almost any telecommunications device in the United States.
Countersurveillance refers to measures that are usually undertaken by the public to prevent surveillance, including covert surveillance. Countersurveillance may include electronic methods such as technical surveillance counter-measures, which is the process of detecting surveillance devices. It can also include covert listening devices, visual surveillance devices, and countersurveillance software to thwart unwanted cybercrime, such as accessing computing and mobile devices for various nefarious reasons. More often than not, countersurveillance will employ a set of actions (countermeasures) that, when followed, reduce the risk of surveillance. Countersurveillance is different from sousveillance, as the latter does not necessarily aim to prevent or reduce surveillance.
Cellphone surveillance may involve tracking, bugging, monitoring, eavesdropping, and recording conversations and text messages on mobile phones. It also encompasses the monitoring of people's movements, which can be tracked using mobile phone signals when phones are turned on.
Network eavesdropping, also known as eavesdropping attack, sniffing attack, or snooping attack, is a method that retrieves user information through the internet. This attack happens on electronic devices like computers and smartphones. This network attack typically happens under the usage of unsecured networks, such as public wifi connections or shared electronic devices. Eavesdropping attacks through the network is considered one of the most urgent threats in industries that rely on collecting and storing data. Internet users use eavesdropping via the Internet to improve information security.
A microphone blocker is a phone microphone connector used to trick feature phones that have a physical microphone switch to disconnect the microphone. Microphone blockers won't operate on smartphones or laptops because the microphone is controlled with software rather than a physical switch.
