The vast majority – 91% – of Americans believe that consumers have lost control over how personal information is collected and used by companies, according to a survey.
A further 80% also felt that Americans should be concerned about government surveillance, Pew Research suggested.
It looked at attitudes to privacy and data in the wake of Edward Snowden’s allegations about government snooping.
One expert described the findings as “unsurprising”.
The high level of media attention given both to the Snowden allegations and to large-scale data breaches among well-known US brands means concerns about privacy are at an all-time high, according to report author Mary Madden.
