Computer and network security.
Recent test of the 4th amendment (prohibiting unlawful searches and seizures): Use of thermal imaging equipment to find individuals growing marijuana. Is a warrant necessary before use?
US Supreme Court, Kyllo v. United States, 6/11/2001: ``Consequently, the Court ruled that the use of surveillance technology to obtain information about things, people, conditions, or activities inside a home is a 'search' if, (1) the technology enables officers to see, hear, or detect things that could otherwise be detected only by means of a physical intrusion into the house, and (2) the technology is not in general public use. In the words of the Court:
Where, as here, the Government uses a device that is not in general public use, to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a 'search' and is presumptively unreasonable without a warrant,Applying this test to thermal scanning of a home, the Court ruled a warrant is required because scanners furnish officers with information that could otherwise be obtained only by means of a physical intrusion.''

A similar technology: The use of a laser, trained upon a window, to listen in on conversations.
Points of creation of public information: grocery store loyalty programs (easily circumvented -- give false information, trade cards), automotive black boxes, GPS-enabled cell phones, RFID technology (a CA school planned to track children via RFID badges. Plan dropped.)
