Information Commissioner’s Office (ICO) has reviewed the public Wi-Fi networks available around the UK, and the levels of personal data requested from individuals wanting to connect. ICO found a significant variation in the amount of data requested from users, ranging from no requests for personal data, to the user’s full name, postal, telephone and email address details as well as gender and date of birth. The ICO also found that, generally, these requests were processed for marketing purposes. A number of practical suggestions for users have been provided by ICO, who will also be contacting the Wi-Fi providers reviewed to suggest any necessary improvements.
