While 71% of UK web users worry about the amount of personal information held online about them, 32% would still hand over confidential information, a new survey by security and computer management firm Faronics finds. One-third would hand over a password, bank account number or their mother's maiden name via email or social networks to someone they don't know. Many users will trust people they don't know when using sites like LinkedIn as they could be on the lookout for new job opportunities. One-third of respondents admitted to accepting contact requests on LinkedIn from people they don't know. Just 15% of Facebook users admitted doing the same.
