One method to protect computer data from hackers is an encryption chip. The most recent of these is called the Clipper, and it can be installed in telephones, faxes and computer circuitry. Basically, data sent over a communication device is processed by the chip, and sent to a receiving machine which interprets the information via its own chip. Anyone attempting to intercept data illegally outside of this two-way process will receive nonsense. However, as the government has the only “key” to this encryption chip, civil rights activists claim it is an infringement on the right to free speech.
