Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transaction apparatus such as an automatic teller machine (ATM) in a bank or the like, and an electronic journal such as a bookkeeping machine, and more particularly to a transaction card or a passbook. The present invention relates to an image data recording apparatus capable of reading a part of data as image data and encrypting the image data to ensure authentication and confidentiality.

Recently, automatic machines such as ATMs and bookkeeping machines have become widespread in financial institutions such as banks. However, in such a device, the authenticity of a customer medium such as a transaction card or a passbook can be verified in order to prove the transaction content. Some data needs to be recorded in the journal.

Because of the nature of an automatic machine, a transaction is completed without any staff such as tellers. Therefore, in the unlikely event of a trouble with the customer regarding the transaction content, it is necessary to have a record with authenticity. This is because

Conventionally, in a customer medium having an emboss such as a transaction card (hereinafter referred to as a card), a roller is used to make an authentic copy on a pressure-sensitive paper. However, this method is gradually shifting to a method in which an image reader and a printer are combined due to damage to the emboss of a card or the like and the problem of storability of pressure-sensitive paper.

In this case, in order to maintain the authenticity, the information digitized by the image reader is immediately printed on the printer to prevent falsification. However, in order to replenish journal paper, eliminate the need for paper running costs and storage space, and facilitate maintenance management, electronic journal methods that use auxiliary storage media such as floppy disks as journals are being adopted. In this case, a method that can secure authentication and confidentiality is desired.
