Nearly four out of five people in Britain believe their personal information is insecure in the hands of the companies that hold the data, according to a recent survey by Symantec and online price comparison site, Moneysupermarket.com.
The research was commissioned by Symantec to assess attitudes towards online risks from both a consumer and business perspective.
An even higher number, 89 per cent of respondents, believes that reckless or repeated data breaches should be a criminal matter and punishable by imprisonment, with four out of five people saying it should be a 'one strike and you're out' rule when it comes to data loss.
This low level of consumer trust could have a vast impact on the reputation and brand value of a company, when taking into account the response from businesses.
"These statistics are very concerning for business, particularly in the current unstable market conditions," said John Brigden, senior vice president for Europe, the Middle East and Africa at Symantec.
"Not only do they risk losing large numbers of customers following an incident of data loss, but almost 60 per cent of companies said it would be a lot harder to attract new customers once the reputation had been tarnished."
A further 75 per cent of consumers are concerned by how much information companies hold about them, whether online or offline, and a staggering 93 per cent will not provide personal details to a company which has past problems of losing data.
When questioned on the trustworthiness of public companies, half of those polled rated the Government as the least trustworthy organisation.
"Today we all have an enormous digital footprint, whether we realise it or not," said Brigden. "Every time we shop online, bank online or increasingly simply surf the web, we are giving away our personal information, and clearly people are concerned how businesses and government handle that data."
Despite their strong views, people are not careful when it comes to protecting their own information, with 73 per cent of respondents not checking what happens to their credit card information when it leaves their sight and 18 per cent not verifying the security of websites they use.
