Recently, remote banking services, such as home trading, cyber securities trading, e-commerce, phone banking and personal computer banking, have been used by financial companies to provide financial services. The convenience of eliminating the time and space constraints that exist between customers is highly preferred among various financial services, and at the same time, the growth of the population is accelerating.

Today, due to the development of various electronic technologies, the spread of tools that can access specific information that requires security through various paths is being changed. As it is developed and announced by non-experts, it is expected that more advanced security technologies will be introduced to block and protect the activities such as access, reading, destruction, cloning, and theft by unauthorized persons. .

Taking advantage of this technological trend, security systems are being developed from various angles to secure security related to authentication of remote financial services systems, which are one of the mainstream areas. It is an electronic signature system.

An electronic signature is a symbol or code included in an electronic document for the purpose of identifying and tampering with a signer that has the same function as a signature that stipulates the creator of the document and affirms that the content displayed on the document has been correctly displayed by the person.

Since the exchange of electronic documents or e-commerce through the information communication network is carried out using the communication network and the communication terminal without the parties meeting in person, an electronic signature is required to verify the identity of the document in order to prevent the contents from being altered or forged by the sender. need.

It is difficult to forge because digital signatures cannot be signed by anyone who has a digital signature generation key, it is possible to prove that the person who signed the electronic signature is difficult, and it is difficult to change an electronic document signed by an electronic signature. In addition, the electronic signature has the effect that it is difficult to deny that the person is due to his intention (denial of containment). This is not only a simple identification and verification of the content, but also a guarantee that the documents you have electronically signed have not been altered, and usually have the ability to go beyond signatures. The activation of electronic documents and electronic commerce requires a credible certification authority that issues digital signatures and institutional devices that can have legal effects such as electronic signatures.

Various electronic signature methods are known in accordance with such social and technical demands. Representative prior applications related to electronic signatures are Korean Patent Publication No. 1999-78671 (name of the invention: fingerprint proof financial transaction system) and Korean Patent Publication.
