Using check box as a method of E Signature.
I'm not sure if this question goes beyond the purpose of this forum but you might be able to give some advice or direction. We have a web form that uses a check box as an action of intent and therefore act as a method of e-signature to the form. My research leads me to believe that in European law a check box is legally Binding ( Slightly different to US but none the less legal ). Further reading has given me doubts with how that data is recorded, basically in a database. This is because even though you can put timestamps to data records, this can be altered or manipulated at a later date.
I have looked at other digital signature services where robust audit trails are integrated in to there system. But trying to integrate one of these into our current system would require out sourcing to advanced API developers.
So I suppose my question is is there a way I can authenticate the data from this form or even create some kind of audit trail to the process.
Thanks in advance.
