Half of all Irish consumers would stop buying from a shop that had their bank details lost or stolen in a cyber attack, according to a new survey.

A study by Deloitte found that six out of ten respondents would only make an online purchase if they felt confident that their data was secure - while three quarters would like to see businesses held responsible for the user data involved in a transaction.

Just over half of consumers actively control their privacy settings online, while only 42% said they understood how to control the level of information available about them.

According to the Deloitte Consumer Review – Navigating Cyber Risks, less than a third of respondents felt their mobile device was as secure as their laptop - but more than half of respondents said they felt comfortable checking their bank balance via mobile.

Commenting on the results of the study, Partner with Deloitte David Hearn said: “This data is valuable to cyber criminals with the result that businesses are exposed to greater cyber risks than ever before.

“While consumers are alert to these dangers, they are distrustful of how organisations protect and use their personal information.

“Consumers want more control over their data privacy and would like businesses to provide them with better tools to protect themselves online.”
