Description

Technical Field [0001] The present invention relates to a digital stamp input system,

The present invention relates to a digital stamp input system and method, and more particularly, to a digital stamp input system and method capable of inserting a stamp image or signature on an electronic document stored in a computer or a smart pad interlocked with a stamp pen and a sensing pad.

BACKGROUND ART [0002] In recent years, an encryption method has been used for transmission and reception of messages in network communication technology.

A public common key scheme is also used for the encryption scheme, but a public key encryption scheme is used for the reason that the management of the key becomes complicated.

In the public key cryptosystem, each individual secretly manages his private key and discloses his or her public key to others.

The other person encrypts the message using the private key of the individual and sends it to the individual. Since the message encrypted by the public key can only be decrypted by the person who knows the secret key, the content of the message is kept secret to the third party.

This public-key cryptosystem has a feature that so-called digital signature can be easily performed.

In other words, when a person, who is a person, performs his or her signature on a predetermined message, it encrypts the message with the secret key of the person. The message encrypted with this secret key can be decrypted only with the public key of the client. Therefore, anyone can decrypt the message with his / her public key and confirm the contents of the original message. The only thing that can be decrypted with A's public key is the one that A's encrypts with the secret key. Therefore, decrypting with the public key of the party means that the party has definitely encrypted the message with the private key of the party.

And since it is only the owner which knows the secret key of the company, it is only the company which can encrypt such.

In this way, since the process that can be performed only by the customer can be confirmed by the other person, it can be regarded as the "signature" of the customer through this process.

However, in the public key cryptosystem including the digital signature, the secret key must be known only to the owner.

In other words, the secret key must be strictly managed by each individual at his / her own responsibility.

However, in order to maintain the strength of the cipher, the length of the key used for the public key cipher system used recently has been proposed or proposed to be about 500 bits to 1000 bits.

Such 500-bit or 1000-bit data is not easily memorable by a person.

Therefore, in general, the public key type secret key is stored in the hard disk in the computer or stored in the IC card.

However, if the secret key is stored in a hard disk or the like in the computer, it is possible that anyone can use the secret key.

Therefore, in many cases, the secret key stored in the hard disk is often protected by a password.

That is, when the secret key is used for digital signature or the like, the user can use the secret key only by inputting the password.
