Digital signatures are increasingly used in commercial transactions and communications. They range in complexity from typewritten names to fingerprint and retina scans.
Electronic signatures are only as secure as the business processes and technology used to create them. High value transactions need better quality electronic signatures – signatures used for these transactions need to be more securely linked to the owner in order to provide the level of assurance needed and to ensure trust in the underlying system.
There is legislation around this area. Most importantly, new regulations mean digital signatures can only be used by individuals not corporations.
For very important transactions you may need to employ ‘Trust Services’ which can involve time stamps, registered delivery services and website authentication.
