As the 21st century dawns, advances in technology endanger our privacy in ways never before imagined. Direct marketers and retailers track our every purchase; surveillance cameras observe our movements; mobile phones will soon report our location to those who want to track us; government eavesdroppers listen in on private communications; misused medical records turn our bodies and our histories against us; and linked databases assemble detailed consumer profiles used to predict and influence our behavior. Privacy -- the most basic of our civil rights -- is in grave peril.Simson Garfinkel -- journalist, entrepreneur, and international authority on computer security -- has spent his career testing new technologies and warning about their implications. Database Nation is his compelling account of how invasive technologies will affect our lives in the coming years. It's a timely, far-reaching, entertaining, and thought-provoking look at the serious threats to privacy facing us today. The book poses a disturbing question: how can we protect our basic rights to privacy, identity, and autonomy when technology is making invasion and control easier than ever before?Garfinkel's captivating blend of journalism, storytelling, and futurism is a call to arms. It will frighten, entertain, and ultimately convince us that we must take action now to protect our privacy and identity before it's too late.Background:Fifty years ago, in 1984, George Orwell imagined a future in which privacy was demolished by a totalitarian state that used spies, video surveillance, historical revisionism, and control over the media to maintain its power. Those who worry about personal privacy and identity--especially in this day of technologies that encroach upon these rights-- still use Orwell's "Big Brother" language to discuss privacy issues. But the reality is that the age of a monolithic Big Brother is over. And yet the threats are perhaps even more likely to destroy the rights we've assumed were ours.Today's threats to privacy are more widely distributed than they were in Orwell's state, and they represent both public and private interests. Over the next fifty years, we'll see new kinds of threats to privacy that don't find their roots in totalitarianism but in capitalism, the free market, advances in technology, and the unbridled exchange of electronic information.Today's Threats to PrivacyThe End of Due Process. Governments and businesses went on a computer-buying spree in the second half of the 20th century, replacing billions of paper files with electronic data-processing systems. But the new computers lacked some very important qualities of the manual systems that they replaced: flexibility, compassion, and understanding. Today, humans often are completely absent from digital decision-making. As a result, we've created a world in which the smallest clerical errors can have devastating effects on a person's life. It's a world where comput- ers are assumed to be correct, and people wrong.

• The Fallibility of Biometrics. Fingerprints, iris scans, and genetic sequences are widely regarded as infallible techniques for identifying human beings. They are so good, in fact, that fifty years from now identification cards and passports will probably not exist. Instead, a global data network will allow anyone on the planet to be instantly identified from the unique markings of their own body. Will it be impossible for people to conceal their identity from the federal government, and if so, is that a good thing? What about concealing your identity from the local drug store? And who controls the databank, anyway? Would they ever need to create "false" identities?
• The Systematic Capture of Everyday Events. We are entering a new world in which every purchase we make, every place we travel, every word we say, and everything we read is routinely recorded and made available for later analysis. But while the technology exists to capture this data, we lack the wisdom to figure out how to treat it fairly and justly. Nevertheless, more and more raw data of every kind is being recorded every day, largely out of fear that if the information is thrown away, it might be needed at some point in the future. The result is an unprecedented amount of data surveillance, the effect of which we have just begun to grasp.
• The Bugging of the Outside World. Orwell thought that the ultimate threat to privacy would be the bugging of bedrooms and offices. Today, it's clear that an equally large threat to freedom is the systematic monitoring of public places. Right or wrong, we have come to expect privacy in public. Microphones, video cameras, and other remote sensing devices, combined with information processing technology, are taking that privacy away.
• The Misuse of Medical Records and the Perversion of Insurance. Traditionally, medical records have been society's most tightly-held personal records. The obligation to maintain patient confidentiality is widely regarded as one of the most basic responsibilities of medical professionals. But patient confidentiality is expensive and inefficient--two factors at odds with healthcare reform. Meanwhile, the core assumptions of healthcare insurance--pooled risk and shared costs--are under attack by companies who wish to insure only the healthy.
• Runaway Marketing. Junk mail, junk faxes, junk e-mail, and telemarketing calls during dinner are just the beginning of the 21st century's runaway marketing campaigns. Marketers increasingly will use personal information to create solicitations that are continual and virtually indistinguishable from news articles, personal letters, and other kinds of non-commercial communications. Where will we as a society draw the line between the right to free speech and the right to be free from intrusion? Will we ever be able to regulate marketers' attempts to convince people to do things that they wouldn't otherwise wish to do? Should we?
• The Commodification of Personal Information. Personally-identified information--your name, your profession, your hobbies, and the other bits that make up your self--is being turned into a valuable property right. But instead of being given to individuals to help them exert control over their lives, the property right is being seized by big business to ensure continued profits and market share.
• Genetic Autonomy. Breakthrough advances in genetics make it possible to predict disease, behavior, intelligence, and many other human traits--but all with differing levels of accuracy. Whether or not this information is correct, it will change how people are perceived and treated. Will it be possible to treat people fairly and equally if there is irrefutable scientific evidence that people are different, with different strengths, different weaknesses, and different susceptibilities to disease? How can genetic information remain confidential when it is shared within families and ethnic groups? How can our own genetic makeup be kept secret when we are constantly shedding DNA from our bodies into the environment?
• Micromanagement of Intellectual Property. To boost their profits ever higher, businesses are becoming increasingly vigilant in detecting misuse of their own intellectual property. But piracy is hard to prevent when modern technology can turn every consumer into an electronic publisher. To prevent info-theft, publishers are turning to increasingly intrusive techniques for spying on their customers. What can we do, as both producers and consumers of intellectual property, to make sure that everyone gets their fair share and a fair shake?
• The Individual as Terrorist. Astonishingly lethal technologies are now widely available throughout society, and people who resort to violence are more likely than ever before to use these technologies. How can society reasonably protect itself from random acts of terrorism without putting every single person under surveillance? How can society protect itself from systematic abuses by law enforcement officials, even when those abuses seem to be in the public interest?
• Intelligent Computing. The utmost threat to privacy will be intelligent computers--machines that can use human-like reasoning powers, combined with blinding calculating speed, to assemble coherent data portraits, to interpret and anticipate our mental states, and to betray us with false relationships. These awesome machines of the not-too-distant future will ultimately change of the rules on which our society is built.
