US study finds online privacy concerns on the rise
Americans are sharing more personal information online than ever, but they also want to better control who can see it, according to a study released Thursday by the Pew Research Center's Internet and American Life Project.
The study says privacy concerns are growing, with 50 percent of Internet users saying they are worried about the information available about them online, up from 33 percent in 2009. Meanwhile, 86 percent of people surveyed have tried at least one technique to hide their activity online or avoid being tracked, such as clearing cookies or their browser history or using encryption.
People cite various reasons. About one-third said they had tried to conceal their activity from hackers or criminals, while 28 percent have tried to block advertisers. Others said they wanted to keep information private from family members or spouses, employers or the government.
"People choose different strategies for different activities, for different content, to mask themselves from different people, at different times in their lives," said Mary Madden, a senior researcher at Pew. "What they clearly want is the power to decide who knows what about them."
The report comes after a national debate erupted again over privacy and national security when a former National Security Agency contractor, Edward Snowden, leaked details of secret government surveillance programs.
The study found that 68 percent of people agreed that the law is insufficient to protect their privacy.
The Pew study, done with help from Carnegie Mellon University, is based on data from 792 Internet and smartphone users contacted by telephone by Princeton Survey Research Associates International from July 11-14. The margin of error is 3.8 percentage points.
