The Traveler

Privacy had become a convenient fiction. Kennard Nash once lectured on that subject to a group of Evergreen Foundation employees. The new electronic monitoring had changed society; it was as if everyone had been moved into a traditional Japanese house with interior walls constructed of bamboo and paper. Although you could hear people sneezing, talking, and making love, the social assumption was that you shouldn’t pay attention to it. You had to pretend the walls were solid and soundproof. People felt the same way when they walked past a surveillance camera or used a cell phone. These days the authorities were using special X-ray machines at Heathrow Airport that could see through passengers’ clothes. It was disturbing to realize that different organizations were watching you, listening to your conversations, and tracking your purchases-so most people pretended that it wasn’t true.

Government officials who supported the Brethren had provided access codes to crucial databases. The largest source was the Total Information Awareness system, established by the American government after the passage of the United States Patriot Act. The TIA database was designed to process and analyze every computer-connected transaction in the country. Whenever a person used a credit card, checked out a library book, transferred money overseas, or went on a trip, the information was entered into the centralized database. A few libertarians objected to this intrusion, so the government transferred control of the program to the intelligence community and changed its name to the Terrorism Information Awareness system. Once the word “Total” was replaced by the word “Terrorism,” all the criticism stopped.

Other countries were passing new security laws and setting up their own versions of TIA. In addition, a variety of privately owned companies were collecting and selling personal information. If the Tabula employees at the computer center in London couldn’t obtain the access codes, they had software programs called Peephole, Hacksaw, and Sledgehammer that allowed them to break through firewalls and enter every database in the world.

Boone felt that the most promising weapons in the battle against the Brethren’s enemies were the new computational immunology programs. The CI programs had originally been developed to monitor the Royal Mail’s computer system in England. The Brethren’s programs were even more powerful. They treated the entire Internet as if it were an enormous human body. The programs acted like electronic lymphocytes that targeted dangerous ideas and information.

During the last few years, CI programs had been released onto the Internet by the Brethren’s computer team. The self-contained programs wandered unnoticed through thousands of computer systems. Sometimes they lingered like a lymphocyte in a person’s home computer, waiting for an infectious idea to appear. If they found something suspicious, the program would return to the host computer in London for further instructions.

The Brethren scientists were also experimenting with a new interactive program that could actually punish the Brethren’s enemies, like a cluster of white blood cells dealing with an infection. The CI program identified people who mentioned the Travelers or the Harlequins in their Internet communications. Once that was done, the program automatically placed a data-destroying virus in the owner’s computer. A small proportion of the most dangerous computer viruses on the Internet had been created by the Brethren or their government allies. It was easy to place the blame on a seventeen-year-old computer hacker living in Poland.

Maya had been tracked down using both computational immunology and a conventional data scan. Three days earlier, the Harlequin had entered an automobile parts warehouse and killed some mercenaries. When Maya fled the area, she’d either had to walk, get a ride from someone, buy a car, or find public transportation. The computer center in London had sorted through Los Angeles police reports involving a young woman in the target area. When that wasn’t successful, they entered taxi company computer systems to discover what passengers hired cabs during the four-hour period after the murders. These pickup and drop-off addresses were matched against information obtained by the CI programs. The central computer had the names and addresses of thousands of people who might help the Travelers or the Harlequins.
