The French engineering school Epitech published a survey on this topic. They polled 1032 persons.

Sorry, the report is in French. Nevertheless, the most interesting out comes:

• Among the people who use Internet at work for personal use, 47% believe that it may cripple the security of their company 🙁 And they do it nevertheless!!!
• 61% feel safe on Internet
• 96% are aware that they leave many traces on Internet. This is a very positive point. I was not expecting such level of awareness 🙂
• This information leakage worries 52% only.
• Only 8% would trust the government to guarantee their security on Internet.
• 94% believe that it is possible to spy exchanges on Internet
• Furthermore, 44% believe that spying can be done by anybody.
• 62% would not give away privacy for more security. Nevertheless, 23% would! 🙁
• 80% believe that ITC may lead to establishing files on every body. Big Brother

I was more pessimistic. People seem more aware of privacy and security issues on Internet then I thought. Unfortunately, we do not see the job categories of the polled people.

Would the data in other countries be similar?
