Online privacy fears stoked by Google, Twitter, Facebook data collection arms race

This week's revelations that Google Inc, Twitter and other popular Internet companies have been taking liberties with customer data have prompted criticism from privacy advocates and lawmakers, along with apologies from the companies.

They are the latest in a long line of missteps by large Internet companies that have faced little punishment for pushing privacy boundaries, which are already more expansive than most consumers understand.

Despite all the chatter about online privacy and the regular introductions of proposed data protection laws in Congress, Silicon Valley is in the midst of a veritable arms race of personal data collection that is intensifying.

Many innovative companies, most prominently Facebook, base virtually all of their services on the ability to personalize, which requires them to know their users well. Their business models likewise depend to an increasing degree on the ability to target a banner advertisement or other marketing pitch to an individual. Millions of times each day, the right to advertise to a specific user is auctioned off in a fraction of a second by computers talking to one another.

For both the buyers and the sellers of the advertising, the business advantage goes to the participant with the most knowledge, and that race is driving companies like Google to learn as much about its users as Facebook does.
