Telephone tapping (or wire tapping/wiretapping in the US) is the monitoring of telephone and Internet conversations by a third party, often by covert means. WireTap is a half-hour radio show that airs on CBC Radio One Sunday afternoons at 100 pm (local time 400 pm in the Pacific Time Zone) and again on Wednesday Basic principle A traditional landline telephone system also known as "plain old telephone service" (POTS, commonly handles both signaling and audio information The Internet is a global system of interconnected Computer networks The telephone tap or wire tap received its name because, historically, the monitoring connection was applied to the wires of the telephone line being monitored and drew off or tapped a small amount of the electrical signal carrying the conversation. Legalized wiretapping by police or other recognized governmental authority is otherwise known as lawful interception. Lawful interception (aka Wiretapping) is the interception of telecommunications by law enforcement agencies (LEA's and intelligence services in accordance with local law and

Passive wiretapping attempts only to observe the flow and gain knowledge of the information it contains. Active wiretapping attempts to alter the data or otherwise affect the flow of data.

Legal status

Main article: Telephone recording laws

Telephone tapping is officially strictly controlled in many countries to safeguard an individual's privacy; this is the case in all developed democracies. Telephone recording laws are laws that govern the civilian recording of telephone conversations by the participants (as opposed to laws controlling government or law enforcement Privacy is the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively Democracy is a form of government in which the supreme power is held completely by the people under a free electoral system In theory, telephone tapping often needs to be authorized by a court, and is, again in theory, normally only approved when evidence shows it is not possible to detect criminal or subversive activity in less intrusive ways; often the law and regulations require that the crime investigated must be at least of a certain severity. A court is a forum used by a power base to adjudicate disputes and dispense civil, labour administrative and criminal Justice under its The Law of evidence governs the use of Testimony (eg oral or written statements such as an Affidavit) and exhibits (e In the sociological field, crime is the breach of a rule or Law for which some governing authority or force may ultimately prescribe a Punishment Subversion refers to an attempt to overthrow structures of Authority, including the State. In many jurisdictions however, permission for telephone tapping is easily obtained on a routine basis without further investigation by the court or other entity granting such permission. Illegal or unauthorised telephone tapping is often a criminal offense. However, in certain jurisdictions such as Germany, courts will accept illegally recorded phone calls without the other party's consent as evidence. Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe.

In the United States, federal agencies may be authorized to engage in wiretaps by the United States Foreign Intelligence Surveillance Court, a court with secret proceedings, in certain circumstances. The United States of America —commonly referred to as the The United States Foreign Intelligence Surveillance Court (or FISC) is a U

Under United States federal law and most state laws there is nothing illegal about one of the parties to a telephone call recording the conversation, or giving permission for calls to be recorded or permitting their telephone line to be tapped. However the Telephone recording laws in some U. Telephone recording laws are laws that govern the civilian recording of telephone conversations by the participants (as opposed to laws controlling government or law enforcement S. states require only one party to be aware of the recording, while other states require both parties to be aware. It is considered better practice to announce at the beginning of a call that the conversation is being recorded.

Methods

Official use

Main article: Lawful interception

The contracts or licenses by which the state controls telephone companies often require that the companies must provide access for tapping lines to the security services and the police. Lawful interception (aka Wiretapping) is the interception of telecommunications by law enforcement agencies (LEA's and intelligence services in accordance with local law and A telephone company (or telco) provides Telecommunications services such as Telephony and Data communications Most of the largest telcos whatever An intelligence agency is a governmental agency that is devoted to the Information gathering (known in the context as " intelligence " Police are agents or agencies usually of the executive, empowered to enforce the law and to effect public and social order through the legitimatized use of force In the U. S. , telecommunications carriers are required by law to cooperate in the interception of communications for law enforcement purposes under the terms of CALEA. The Communications Assistance for Law Enforcement Act ( CALEA) is a United States Wiretapping law passed in 1994 (Pub

When telephone exchanges were mechanical, a tap had to be installed by technicians, linking circuits together to route the audio signal from the call. In the field of Telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls Now that many exchanges have been converted to digital technology tapping is far simpler and can be ordered remotely by computer. Telephone services provided by cable TV companies also use digital switching technology. The public switched telephone network ( PSTN) is the network of the world's public circuit-switched Telephone networks in much the same way that the If the tap is implemented at a digital switch, the switching computer simply copies the digitized bits that represent the phone conversation to a second line and it is impossible to tell whether a line is being tapped. In the field of Telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls A well-designed tap installed on a phone wire can be difficult to detect. The noises that some people believe to be telephone taps are simply crosstalk created by the coupling of signals from other phone lines. In Electronics, the term crosstalk ( XT) refers to any phenomenon by which a signal transmitted on one circuit or channel of a Transmission system In Electronics and Telecommunication, coupling is the desirable or undesirable Transfer of energy from one medium, such as a metallic wire or

Data on the calling and called number, time of call and duration, will generally be collected automatically on all calls and stored for later use by the billing department of the phone company. These data can be accessed by security services, often with fewer legal restrictions than for a tap. This information used to be collected using special equipment known as pen registers and trap and trace devices and U. A pen register is an electronic device that records all numbers dialed from a particular Telephone line A trap and trace device is an electronic device used to record and trace all communication signals from a telecommunication system S. law still refers to it under those names. Today, a list of all calls to a specific number can be obtained by sorting billing records. A telephone tap during which only the call information is recorded but not the contents of the phone calls themselves, is called a pen register tap.

For telephone services via digital exchanges, the information collected may additionally include a log of the type of communications media being used (some services treat data and voice communications differently to conserve bandwidth).

Unofficial use

A telephone recording adapter (in-line tap). Carnivore is a system implemented by the Federal Bureau of Investigation that is analogous to wiretapping except in this case E-mail and other Communications The phone jack connects to the wall socket while the phone being monitored is connected to the adapter's socket. The audio plug connects to the recording device (computer, tape recorder, etc). A TRS connector, also called an audio jack, phone plug, jack plug, stereo plug, mini-jack, or mini-stereo, is a common

It is also possible to tap conversations unofficially. There are a number of ways to monitor telephone conversations:

• Recording the conversation - the person making/receiving the call records the conversation using a coil tap (telephone pickup coil) attached to the ear-piece, or they fit an in-line tap with a recording output. A coil tap is a wiring feature found on some electrical Transformers Inductors and coil pickups, all of which are sets of wire coils Both of these are easily available through electrical shops. A more modern alternative is to use telephone recording devices connected to computers, such as call recording software. Call recording software or call logging software allows a party to record a telephone converstation either PSTN or VoIP to a digital File format, usually

• Direct line tap - involves a direct electrical connection to the line using a Butt set or a Beige box, or an induction coil. A lineman's handset is a special type of Telephone used by technicians for installing and testing Local loop Telephone lines It may also This article refers to beige box Phone phreaking devices For information about beige boxes in personal computing see Beige box An induction coil or "spark coil" ( archaically known as a Ruhmkorff coil) is a type of Disruptive discharge Coil. An induction coil is usually placed underneath the base of a telephone or on the back of a telephone handset to pick up the signal inductively. With a direct connection, there will be some drop in signal levels because of the loss of power from the line, and it may also generate noise on the line. A well designed induction tap does not drain voltage or current from the line because it isn't physically connected to the phone line. Direct taps sometimes require regular maintenance, either to change tapes or replace batteries, which may give away their presence.

• Radio tap - this is like a bug that fits on the telephone line. A covert listening device, more commonly known as a bug, is usually a combination of a Miniature Radio transmitter with a Microphone. It can be fitted to one phone inside the house, or outside on the phone line. It may produce noise (there might even be signal feedback on the monitored line on poorly made equipment) to inadvertently alert the caller. Modern state of the art equipment operates in the 30-300 GHz range. The unit is powered from the line to be maintenance free, and only transmits when a call is in progress. These devices tend to be low powered because the drain on the line would become too great, however a state of the art receiver could be located as far away as ten kilometers under ideal conditions, but is usually located within a radius of 1 to 3 km. Research however has also shown that a satellite can be used to receive emissions in the range of a few milliwatts.

Electromagnetic radiation takes the form of self-propagating Waves in a Vacuum or in Matter.

Location data

Mobile phones are, in surveillance terms, a major liability. Surveillance is the monitoring of Behavior. Systems surveillance is the process of monitoring the behavior of people objects or processes within systems for conformity This liability will only increase as the new third-generation (3G) phones are introduced, as the base stations will be located closer together. 3G is the third generation of mobile phone standards and Technology, superseding 2 The term base station can be used in the context of Land surveying, Wireless computer networking, and Wireless communications. For mobile phones the major threat is the collection of communications data. This data does not only include information about the time, duration, originator and recipient of the call, but also the identification of the base station where the call was made from, which equals its approximate geographical location. This data is stored with the details of the call and has utmost importance for traffic analysis. Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in Communication.

It is also possible to get greater resolution of a phone's location by combining information from a number of cells surrounding the location, which cells routinely communicate (to agree on the next handoff—for a moving phone) and measuring the timing advance, a correction for the speed of light in the GSM standard. In the GSM cellular mobile phone standard timing advance value corresponds to the length of time a signal from the Mobile phone takes to reach the Base station GSM ( Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for Mobile phones in the This additional precision must be specifically enabled by the telephone company - it is not part of ordinary operation.

The second generation mobile phones (circa 1978 through 1990) could be easily monitored by anyone with a 'scanning all-band receiver' because the system used an analog transmission system-like an ordinary radio transmitter. A scanner is a Radio receiver that can automatically tune or scan, two or more discrete frequencies, stopping when it finds a signal on one The third generation digital phones are harder to monitor because they use digitally-encoded and compressed transmission. However the government can tap mobile phones with the cooperation of the phone company. It is also possible for organizations with the correct technical equipment to monitor mobile phone communications and decrypt the audio. A device called an "IMSI-catcher" pretends to the mobile phones in its vicinity to be a legitimate base station of the mobile phone network, subjecting the communication between the phone and the network to a man in the middle attack. An IMSI-catcher is a device for forcing the transmission of the International Mobile Subscriber Identity (IMSI and intercepting GSM Mobile phone In Cryptography, the man-in-the-middle attack or bucket-brigade attack (often abbreviated MITM) sometimes Janus attack, is a This is possible because while the mobile phone has to authenticate itself to the mobile telephone network, the network does not authenticate itself to the phone. Once the mobile phone has accepted the IMSI-catcher as its base station the IMSI-catcher can deactivate GSM encryption using a special flag. All calls made from the tapped mobile phone go through the IMSI-catcher and are then passed on to the mobile network. Some phones include a special monitor mode (activated with secret codes or special software) which displays GSM operating parameters such as encryption while a call is being made. There is no defense against IMSI-catcher based eavesdropping, except using end-to-end call encryption; products offering this feature, secure telephones, are already beginning to appear on the market, though they tend to be expensive and incompatible with each other, which limits their proliferation. A secure telephone is a Telephone that provides voice security in the form of end-to-end Encryption for the telephone call and in some cases also the mutual

There were proposals for European mobile phones to use stronger encryption, but this was opposed by a number of European countries, including the Netherlands and Germany, which are among the world's most prolific telephone tappers (over 10,000+ phone numbers in both countries in 2003). The Netherlands ( Dutch:, ˈnedərlɑnt is the European part of the Kingdom of the Netherlands, which consists of the Netherlands the Netherlands Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe.

One-ring calls

These calls cannot be recognized by caller ID as a CID displays the caller's number only between the first two rings. For the protein involved in the synthesis of Major histocompatibility complex II see CLIP (protein. The purpose of a one-ring call is usually to determine if a person is using the phone. Accessing the telephone exchange is one way to determine the origin of these calls. In the field of Telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls Last Call, also known as *69, also gives the CID number even if it only rings once.

History

During the American Civil War, government officials under President Abraham Lincoln eavesdropped on telegraph conversations. Causes of the war See also Origins of the American Civil War, Timeline of events leading to the American Civil War The coexistence of a slave-owning South Abraham Lincoln (February 12 1809 &ndash April 15 1865 the sixteenth President of the United States, successfully led his country through its greatest internal Telephone wiretapping began in the 1890s, following the invention of the telephone recorder. Wiretapping has also been carried out under most Presidents, usually with a lawful warrant since the Supreme Court ruled it constitutional in 1928. Domestic wiretapping under the Clinton administration led to the capture of Aldrich Ames, a former Soviet spy in 1994. Aldrich Hazen Ames (born May 26 1941) is a former Central Intelligence Agency Counter-intelligence officer and analyst who in 1994 was convicted US Senator Robert F. Kennedy monitored the activity of Martin Luther King Jr. by wiretapping in 1966. Robert Francis "Bobby" Kennedy (November 20 1925 – June 6 1968 also called RFK, was the United States Attorney General from 1961 to 1964 and a Martin Luther King Jr ( January 15, 1929 April 4, 1968) was an American clergyman, Activist and prominent leader

Before the Japanese attack on Pearl Harbor and the subsequent entry of the United States into World War II, the U. S. House of Representatives held hearings on the legality of wiretapping for national defense. Significant legislation and judicial decisions on the legality and constitutionality of wiretapping had taken place years before World War II. ^[1] However, it took on new urgency at that time of national crisis. The actions of the government regarding wiretapping for the purpose of national defense in the current war on terror have drawn considerable attention and criticism. In the World War II era, the public was also aware of the controversy over the question of the constitutionality and legality of wiretapping. Furthermore, the public was concerned with the decisions that the legislative and judicial branches of the government were making regarding wiretapping. ^[2]

In the Greek telephone tapping case 2004-2005 more than 100 mobile phone numbers belonging mostly to members of the Greek government, including the Prime Minister of Greece, and top-ranking civil servants were found to have been illegally tapped for a period of at least one year. The Greek telephone tapping case of 2004-2005, also referred to as Greek Watergate, involved the illegal tapping of more than 100 Mobile phones on the The Prime Minister of Greece ( Πρωθυπουργός της Ελλάδος) is the Head of government of the Hellenic Republic and the leader of The Greek government concluded this had been done by a foreign intelligence agency, for security reasons related to the 2004 Olympic Games, by unlawfully activating the lawful interception subsystem of the Vodafone Greece mobile network.

The most recent case of U. S. wiretapping was the NSA warrantless surveillance controversy discovered in December 2005. The NSA warrantless surveillance controversy concerns Surveillance of persons within the United States incident to the collection of Foreign intelligence by the It aroused much controversy, after President George W. Bush admitted to violating a specific federal statute (FISA) and the warrant requirement of the Fourth Amendment to the United States Constitution. George Walker Bush ( born July 6 1946 is the forty-third and current President of the United States. The Foreign Intelligence Surveillance Act of 1978 (" FISA ",) is an Act of Congress which prescribes procedures for the physical and electronic Surveillance The President claimed his authorization was consistent with other federal statutes (AUMF) and other provisions of the Constitution, was necessary to keep America safe from terrorism, and could lead to the capture of notorious terrorists responsible for 9/11. Terrorism is the systematic use of terror especially as a means of coercion

In the most recent issue concerning warrantless wiretapping, earlier in 2007 a Foreign Intelligence Surveillance Act (FISA) court ruled that it increased restraints on the National Security Agency (NSA). The new court ruling requires the NSA to obtain a warrant when intercepting or eavesdropping on foreign-to-foreign intelligence if it passes through any U. S. networks. The Bush Administration in response to this passed a stopgap legislation very quickly through congress that only temporarily relieves the NSA of this prior ruling. Director of National Intelligence Mike McConnell said to Congress that the new ruling could potentially decrease the amount of useful information they collected on groups like al Qaeda by almost two thirds. He also stated that applying for a warrant can run up to 90 pages and can be time consuming and labor intensive. ^[3]

Very active in this issue is The American Civil Liberties Union (ACLU). The ACLU has brought about many legal cases challenging the constitutionality of the bill, inserting that it violates our right to free speech and privacy. They have filed lawsuits, motions, and complaints in over 27 states so far to oppose any legislation that encourages unchecked government surveillance. ^[4] In response to the government arguments, Caroline Fredrickson, Director of the ACLU Washington Legislative Office has said of the bill: “Where will Congress go from here? More unfettered power for an administration that has no respect for the privacy of the citizenry that elected it?”^[5]

The stopgap that was hastily put in place by the Bush Administration expires in February 2008 but Congress and FISA are trying to reach a compromise on the details of the bill to be passed. To reach a compromise both sides are reaching a middle ground on determining when a warrant is or is not necessary. ACLU advocates are pushing to require NSA to provide individual warrants when Americans are involved and on the other hand, U. S. intelligence agencies and the Administration would like as few obstacles in their way of intercepting private information. Both sides have both shown the possibility for a compromise to accept a Bill that would require a FISA court to approve NSA’s procedures while intercepting foreign intelligence when it involves Americans. ^[3]

However, a new addition to this bill, that was recently insisted on by President Bush and Mike McConnell, would grant immunity to telecommunications companies for any "intelligence activity involving communications" that was "designed to detect or prevent a terrorist attack" or attack preparations. ^[6] The Bush Administration has acknowledged that intelligence agencies conducted warrantless eavesdropping on Americans with the help of Telecom companies such as Verizon, AT&T, and Qwest. ^[7] All three of these Telecom companies face multiple civil lawsuits related to their handling of phone records and the passing of this bill would grant them immunity.

In favor of the bill, McConnell has said, such immunity is necessary to prevent the telecoms from being bankrupted and to encourage them to continue to cooperate with intelligence agencies. Bush has said that he will veto any intelligence bill passed that does not include immunity. ^[6] Liz Rose, spokeswoman for the Washington office of the ACLU, says the language of the bill is a "blank check" that would cover not only the warrantless wiretapping program the Bush administration has acknowledged, but any unconfirmed or previously unknown program. Sen. Russ Feingold, D-Wis. , promised to lead a filibuster to block approval of retroactive immunity. "Retroactive immunity set the terrible precedent that breaking the law is permissible and companies need not worry about the privacy of their customers," Feingold said. ^[6]

The bill now goes to the Senate Judiciary Committee, and in the Senate, committees have split on how to handle immunity. With many senators outspoken about their reservations of the bill, more information is needed to continue the proceedings. For now, legislation is stalled in the House. ^[7]
