E-mail Privacy
Email privacy is a broad topic dealing with issues of unauthorized access to, and inspection of, electronic mail, or unauthorized tracking spy pixel, when a user reads an email. This unauthorized access can happen while an email is in transit, as well as when it is stored on Message transfer agent, email servers or on a user's computer, or when the user reads the message. In countries with a constitutional guarantee of the secrecy of correspondence, whether email can be equated with Letter (message), letterstherefore having legal protection from all forms of eavesdroppingis disputed because of the very nature of email. In 2022 a lookback at an 1890 law review article about personal privacy (the "right to be left alone”) noted how "digital technology has been allowed to invade our lives" both by personal choice and behavior, and also by various forms of ongoing monitoring. An email has to go through potentially untrustworthy intermediate computers (email servers, ISPs) before r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Mail
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic (digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simulta ...

Information Leakage
Information leakage happens whenever a system that is designed to be closed to an eavesdropper reveals some information to unauthorized parties nonetheless. In other words: Information leakage occurs when secret information correlates with, or can be correlated with, observable information. For example, when designing an encrypted instant messaging network, a network engineer without the capacity to crack encryption codes could see when messages are transmitted, even if he could not read them. Risk vectors A modern example of information leakage is the leakage of secret information via data compression, by using variations in data compression ratio to reveal correlations between known (or deliberately injected) plaintext and secret data combined in a single compressed stream. Another example is the key leakage that can occur when using some public-key systems when cryptographic nonce values used in signing operations are insufficiently random. Bad randomness cannot protect proper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Communications Privacy Act
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 ( ''et seq.''), added new provisions prohibiting access to stored electronic communications, i.e., the Stored Communications Act (SCA, ''et seq.''), and added so-called pen trap provisions that permit the tracing of telephone communications ( ''et seq.''). ECPA was an amendment to Title III of the Omnibus Crime Control and Safe Streets Act of 1968 (the Wiretap Statute), 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 (20 Overview "Electronic communications" means any transfer of signs, signals, wr ...

Stored Communications Act
The Stored Communications Act (SCA, codified at 18 U.S.C. Chapter 121 §§ 2701–2712) is a law that addresses voluntary and compelled disclosure of "stored wire and electronic communications and transactional records" held by third-party internet service providers (ISPs). It was enacted as Title II of the Electronic Communications Privacy Act of 1986 (ECPA). The Fourth Amendment to the U.S. Constitution protects the people's right "to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures". However, when applied to information stored online, the Fourth Amendment's protections are potentially far weaker. In part, this is because the Fourth Amendment defines the "right to be secure" in spatial terms that do not directly apply to the "reasonable expectation of privacy" in an online context. The Fourth Amendment has been stressed as a right that protects people and not places, which leaves the interpretation of the amendment's languag ...

IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pen Register
A pen register, or dialed number recorder (DNR), is an electronic 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 United States statutes governing pen registers are codified unde18 U.S.C., Chapter 206 Definitions The term ''pen register'' originally referred to a device for recording telegraph signals on a strip of paper. Samuel F. B. Morse's 1840 telegraph patent described such a register as consisting of a lever holding an armature on one end, opposite an electromagnet, with a fountain pen, pencil or other marking instrument on the other end, and a clockwork mechanism to advance a paper recording tape under the marker. The term ''telegraph register'' came to be a generic term for such a recording device in the later 19th century. Where the record was made in ink with a pen, the t ...

Expectation Of Privacy
Expectation of privacy is a legal test which is crucial in defining the scope of the applicability of the privacy protections of the Fourth Amendment to the United States Constitution. It is related to, but is not the same as, a ''right to privacy'', a much broader concept which is found in many legal systems (see privacy law). Overall, expectations of privacy can be subjective or objective. Overview There are two types of expectations of privacy: * Subjective expectation of privacy: a certain individual's opinion that a certain location or situation is private; varies greatly from person to person * Objective, legitimate, reasonable expectation of privacy: an expectation of privacy generally recognized by society and perhaps protected by law. Places where individuals expect privacy include residences, hotel rooms, or public places that have been provided by businesses or the public sector to ensure privacy, including public restrooms, private portions of jailhouses, or phone boo ...

Fourth Amendment To The United States Constitution
The Fourth Amendment (Amendment IV) to the United States Constitution is part of the Bill of Rights. It prohibits unreasonable searches and seizures. In addition, it sets requirements for issuing warrants: warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized. Fourth Amendment case law deals with three main issues: what government activities are "searches" and "seizures," what constitutes probable cause to conduct searches and seizures, and how to address violations of Fourth Amendment rights. Early court decisions limited the amendment's scope to physical intrusion of property or persons, but with ''Katz v. United States'' (1967), the Supreme Court held that its protections extend to intrusions on the privacy of individuals as well as to physical locations. A warrant is needed for most search and seizure activities, but the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petraeus Scandal
The Petraeus scandal is a series of events that garnered strong media attention when an extramarital affair between retired four-star general and then-Director of the Central Intelligence Agency (CIA) David Petraeus and Paula Broadwell became public information. Petraeus had chosen Broadwell to be his official biographer. She co-authored his biography, '' All In: The Education of General David Petraeus'', when Petraeus was the International Security Assistance Force (ISAF) commander. On November 9, 2012, she was reported to have been involved in the extramarital affair with Petraeus that triggered his resignation as Director of the CIA when it was discovered by the Federal Bureau of Investigation (FBI). Summary and chronology The case was initiated by Federal Bureau of Investigation (FBI) agent Frederick W. Humphries II after he received a complaint about cyberstalking from Jill Kelley. Humphries reported it to his superiors and then to Republican congressional leaders Dave Rei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Drop
A dead drop or dead letter box is a method of espionage tradecraft used to pass items or information between two individuals (e.g., a case officer and an agent, or two agents) using a secret location. By avoiding direct meetings, individuals can maintain operational security. This method stands in contrast to the live drop, so-called because two persons meet to exchange items or information. Spies and their handlers have been known to perform dead drops using various techniques to hide items (such as money, secrets or instructions) and to signal that the drop has been made. Although the signal and location by necessity must be agreed upon in advance, the signal may or may not be located close to the dead drop itself. The operatives may not necessarily know one another or ever meet. Considerations The location and nature of the dead drop must enable retrieval of the hidden item without the operatives being spotted by a member of the public, the police, or other security force ...
