This is the fourth bi-annual index of its type from the IT services firm, but the report shows that bank security concerns have soared in the last year, with 92% of respondents saying they were worried about bank card fraud, and 91% saying ID theft was also a major concern.
Citing figures from CIFAS, the UK's fraud prevention service, the study notes that 102,500 cases of bank card fraud were identified in 2010, with many more cases not being reported.
Interestingly, researchers found that people had conflicting feelings about WikiLeaks and the right to reveal secret information.
Nearly three-quarters of UK citizens surveyed (71%) believe that online whistle-blowing sites like WikiLeaks should not be allowed to exist. Despite this, 49% also said they believed in posting secret information online exercises our freedom of speech.
61%, meanwhile, believed that publishing classified information online should be considered an act of treason.
Delving into the report reveals that 63% of respondents are also worried about physical security - notably terrorism - involving large gatherings like the 2012 Olympics. In addition, 74% of UK citizens surveyed for the report said they believed that airports and aeroplanes are vulnerable to a malicious or terrorist attack.
Commenting on the figures, Neil Fisher, vice president of global security services with Unisys, said that they are alarming findings.
"But when you think about the government austerity measures, the security implications of hosting the Olympics in 2012, threats to aviation security - even the recent hoax bomb which made its way from the UK to Turkey undetected - the public would be justified in feeling insecure", he said.
"Knee-jerk approaches to managing security clearly aren't working, as the index rate in the UK reflects. Until government and industry come together to address these vulnerabilities in a more collaborative and integrated fashion, the public's confidence will continue to suffer", he added.
The Unisys security index is a bi-annual global study that provides insights into the attitudes of consumers on a wide range of security related issues. This latest study took in responses from more than 11,700 people in 12 countries, with 953 people in the UK surveyed.
