Abstract: A secure electronics funds or other financial transaction system that provides substantially equivalent security to that obtained by the use of secure point of sale terminals such as automatic teller machines, yet is conducted from unsecure terminal devices such as telephones, is disclosed. A customer registers himself or herself personally, together with information on his or her bank account at a secure transaction processor. A secure terminal is used to generate an encrypted version of a personal identification number (PIN) and provides the encrypted PIN and to the secure transaction processor. The encryption key used during encryption of the PIN is also acquired from either a specific request to, or monitoring data passing from a conventional network security transaction processor. The encrypted PIN is parsed with one portion being stored in the customer record at the secure transaction processor and the other being partially masked and provided back to the customer as an access code.
