Bert- don't we kind of have that system with how faxes work? Obviously, one could set up any fax to say it is from any practice but doesn't the receiving fax have the ability to print the sending fax phone number on the top? Which seems somewhat secure- I would not know how to circumvent that one. The mailorder pharmacies such as Caremark all require faxed prescriptions be faxed from the prescriber's office- so a patient cannot fax in a signed written Rx (for many good reasons)- but Caremark must trust that their fax system is "reading" the originating fax as being legit from the prescriber's office.
