Just how much does the Constitution protect your digital data?The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant if the phone is on or around a person during an arrest.California has asked the justices to refrain from a sweeping ruling particularly one that upsets the old assumption that authorities may search through the possessions of suspects at the time of their arrest.It is hard,the state argues,for judges to assess the implications of new and rapidly changing technologies.The court would be recklessly modest if it followed California’s advice.Enough of the implications are discernable,even obvious,so that the justices can and should provide updated guidelines to police,lawyers and defendants.They should start by discarding California’s lame argument that exploring the contents of a smart phone—a vast storehouse of digital information—is similar to,say,rifling through a suspect’s purse.The court has ruled that police don’t violate the Fourth Amendment when they sift through the wallet or pocketbook of an arrestee without a warrant.But exploring one’s smart phone is more like entering his or her home.A smart phone may contain an arrestee’s reading history,financial history,medical history and comprehensive records of recent correspondence.The development of“cloud computing,”meanwhile,has made that exploration so much the easier.Americans should take steps to protect their digital privacy.But keeping sensitive information on these devices is increasingly a requirement of normal life.Citizens still have a right to expect private documents to remain private and protected by the Constitution’s prohibition on unreasonable searches.As so often is the case,stating that principle doesn’t ease the challenge of line-drawing.In many cases,it would not be overly onerous for authorities to obtain a warrant to search through phone contents.They could still invalidate Fourth Amendment protections when facing severe,urgent circumstances,and they could take reasonable measures to ensure that phone data are not erased or altered while a warrant is pending.The court,though,may want to allow room for police to cite situations where they are entitled to more freedom.But the justices should not swallow California’s argument whole.New,disruptive technology sometimes demands novel applications of the Constitution’s protections.Orin Kerr,a law professor,compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a virtual necessity of life in the 20th:The justices had to specify novel rules for the new personal domain of the passenger car then;they must sort out how the Fourth Amendment applies to digital information now.

问答题Practice 4 Bluetooth is the newest kid on the technology block, and it holds a lot of promise for the assistive technology industry. Named for a 10th Century King of Denmark who unified the kingdoms of Denmark and Norway, Bluetooth is a shot-range wireless communication specification that promises to improve and increase electronic access to a number of environments by overcoming some of the obstacles typical of current technology. Bluetooth technology will enable devices to communicate and transfer data wirelessly and without the line-of-site issues of infra red technology. So how does it work? Bluetooth devices search each other out within their given operational range. Unlike devices that are wired together, Bluetooth devices do not have to be aware of the capabilities or properties of the devices to which they will connect beforehand. Bluetooth devices have a built-in mechanism that lets each device identify itself as well as its capabilities as it connects into this new Bluetooth network. This dynamic network does have a controlling device that designates itself as the master for the connection. Its programming and the capabilities necessary for the given task determine whether or not a device can be a master. For example, a cell phone may act as a master device when connecting to a headset, an ATM, or an information kiosk. However, the same cell phone or headset may act as a slave device to the information kiosk, now acting as the master device, broadcasting emergency evacuation information. The cell phone and kiosk can function in either capacity depending on the required function and their programming.

问答题Practice 6 Fiber-optic lines will form most of the backbone of the information highway, just as they do for the phone system today. Fiber-optic cable is made of long, thin strands of glass rather than wire, and it transmits information in the form of digitized pulses of laser light rather than the radio waves used by coaxial cable. Because light pulses have shorter wavelengths than radio waves, engineers can cram much more data into fiber-optic lines than into other kinds of cables and wires. A single fiber, for example, can handle a mind-boggling 5,000 video signals or more than 500,000 voice conversations simultaneously. This huge capacity allows it to transmit all signals digitally. So noise or static easily can be filtered out. Finally, because glass is an inherently more efficient medium for transmitting information than other materials, a fiber-optic line can transmit a signal thousands of miles without much “signal loss”. Fiber-optic cable, simply put, is the method of choice for transmitting massive quantities of information over long distances. Another key is “digital compression”—a variety of methods for reducing the amount of digital code (streams of ones and zeros) needed to represent a piece of information—whether it is a document, a still picture, a movie or a sound. Digital compression is most critical for transmitting video, because digitized video consumes enormous amounts of space. Just four seconds of a digitized film, for example, would completely fill a 100-megabyte hard drive. A feature film of typical length, if uncompressed, would occupy more than 350 ordinary compact discs. Compression techniques achieve their gins by recording only the changes from one frame to the next, The background image in a movie scene, for example, typically does not change much from one flame to another. In a digital compression scheme, the background would be recorded only once; after that, only the actors’ movements would be captured. One result is more choices—hundreds of channels coming through your cable TV line instead of dozens. Digital compression also makes it easier to piggyback data onto media that were not designed with data in mind: in particular, phone lines.
