(Telecompaper) Less than a third (32 percent) of Europeans believe there are advantages to big data, according to a study conducted by TNS Infratest on behalf of the Vodafone Institute. The survey of 8,000 respondents in eight European countries revealed that even fewer digital users 26 percent thought companies respected the privacy of their personal data, with only 29 percent feeling they had control over what information is collected about them. In terms of the types of companies that Europeans trust to correctly handle their personal data, telecoms operators were trusted by just 18 percent of respondents, slightly above social media companies (11 percent), messaging providers (14 percent) and search engine companies (16 percent).
