Hi Saqib,
Thanks :)
You're right; if the customer can't access their email they can't
access their bank. However, it is not neccessarily a big problem
though, is it ?
Most banks offer other mechanisms to access your account - phone
banking, etc, so if it is an absolute emergency you can use their
backup system.
Also, I would suggest that, unless something goes seriously wrong
with your email provider, it will always be available when you are on
the internet ... Outlook provides a WebAccess system and I imagine the
other big ones would do the same.
I think the most critical issue to deal with if you implemented it
would be the _securing_ your email system. The easiest way to do it is
encrypt the emails. And to make it easy for users to make use of it,
the email providers would need to integrate it or the banks/etc would
need to provide tools that linked in to perform the decryption.
This way the user would only need to remember their general
pass-phrase to utilise their private key to decrypt these emails.

Hello Michael,
Interesting article, and well-written.
The technique you are proposing is very similar to assigning a RSA
SecureID to each of the banc customer. Except in this case the
customer doesn't hold the physical SecureID, instead he/she is sent
the auto-generated number.
One major problem of these kind of systems is that, they are dependent
on 3rd party service being available whenever the customer wants to
access the banc. In this case the 3rd party service is the customer's
personal email provider, which may not be available all the time.
RSA SecureID has the same problem, i.e. what if the customer loses
his/her SecureID and is at a remote location where he/she can not
physically go to banc branch.
Thanks.

Article - A solution to phishing
Hi,
Just a quick little article about a login system that, should (i
think :)), prevent phishing attempts on your site.

Have a look at it and let me know what you think ... and apologies
to anyone if an idea like this is already out there :)
