One time coded access provides solution for data loss

Gridsure : 21 November, 2007  (Technical Article)
In light of recent data breaches in the UK, the importance of data protection warrants the consideration of alternative approaches to user authentication, according to GrIDsure
The latest data breach scandal to hit Britain has raised obvious questions about how valuable information on British citizens is stored. However, it has also re-ignited concerns about the security of current banking practices.

UK authentication expert GrIDsure is concerned that the current Chip and PIN system is outdated, leaving consumers vulnerable to the rising tide of financial fraud and increasingly exposed following cases of data theft such as that hitting the headlines today.

'With children's names and dates of birth believed to be commonly used as passwords, security codes and PIN numbers, it is extremely concerning that this data is out there and vulnerable to thieves,' said Jonathan Craymer, Chairman, GrIDsure. 'As it stands, the only thing preventing people's bank accounts being subjected to fraud is a flaky password or PIN system; with the personal details of 25 million people having been 'misplaced', this is not good news for the consumer.'

'It may come as little consolation to the millions who have been affected, but at least there was no biometric data leaked on this occasion,' continued Craymer. 'Biometrics is still being billed in some circles as a silver bullet, but its fundamental weakness is ignored. If biometric data is stolen, users will end up in a terrible position - unlike a password, there is no option to change these details!'

GrIDsure has developed a radical new approach to proving 'we are who we say we are'. With GrIDsure, users create a new style 'shared secret', by picking a set of squares on a grid. To aid memory recall, they can use patterns or shapes - such as an 'L' or a 'tick'. Because the grid fills itself with random numbers each time it appears, new 'PIN' or pass codes are created (by reading the numbers in the user's chosen squares). GrIDsure works without the need for extra hardware, such as tokens - generating 'one-time' codes that are secure and resilient.
