The Electronic Communications Privacy Act (ECPA), discussed in Chapter 7, is actually a combination of three different provisions. Title I, known as the Wiretap Act, restricts interception of communications while in transit. Title II, known as the Stored Communications Act, restricts the disclosure of communications contents that are stored on a server or in the cloud. Title III, known as the Pen Register Statute, limits the government's ability to obtain non-content communications data (e.g., a list of phone numbers dialed or the to/from lines of email messages).
Title I, Wiretap Act, 18 U.S.C. 2510–2522
