Does anyone know any bank that understands or properly uses PGP or similar digital signing or encryption on communications to/from the bank?
It is probably not something too relevant to most people simply because emailing your bank, or them emailing you, pretty much does not happen. On-line banking is fine for most things and that has a lot of security.
But where you do have a proper bank manager, or a "private banking team" or some such, and you may well want to just email them and get them to just sort something, I would think this would be ideal.
It would allow the convenience of email with the proper security a bank needs. The simplicity of just saying "lost my debit card, can you get me a new one sorted" with the security of the bank knowing it is definitely you asking, and even who you are without you saying.
It would also allow banks to email statements or information as needed in a secure way. They could lose the cost of posting lots of the usual crap and send it by encrypted email.
Basically, I am trying to pitch the idea to Lloyds as they seem quite keen to get us on their private banking package.
The idea is that for a small group dealing with select customers, this sort of extra benefit would be really useful. And if they get their act together - which probably means some central key management - then this could easily extend to more general banking customers.
So, comments please - I'll pass them on to the bank!
