Description

A SYSTEM WHICH CREATES AND MANAGES THE LEGALLY BINDING ELECTRONIC DOCUMENT AND THE METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of electronic documents, and more particularly, to a system and a method for generating and managing electronic documents having legal binding force by reconstructing data and styles recorded by a user into one object.

Recently, with the development of information technology and the rapid increase in the use of the Internet, all individuals and companies can effectively utilize and share accurate information with each other without restriction of time and space.

However, in order to realize paperless transactions without face-to-face contact with a large number of unspecified people over the Internet, documents sent and received online, such as the Internet, cannot be forged or altered in the same way as paper documents are exchanged in real life. The form and content must be treated at all times.

In addition, since such a mechanism should be a legally recognized method in case of emergency, the format of the document under the public key infrastructure (PKI) of the certification body, that is, the authority that can currently authenticate the transaction of electronic information, It provides a technical mechanism for sending and receiving information that has not changed.

When issuing transactions and supporting documents on the Internet, in order to be legally binding on the documents, the electronic documents must be protected against counterfeiting, forgery and disclaimer.

However, in the current method, only the fact of a transaction through electronic signature is focused on the non-repudiation function, which is authenticated, and there is a problem that the forgery and forgery as the document itself cannot be proved. In other words, the user signed an electronic signature during the transaction, using his own unique certificate and private key, so that the user could not deny the transaction in the future. (Signature, context, style) are not considered to be digital signatures.

Currently, electronic document distribution on the Internet can be largely divided into HTML (HyperText Markup Language) based and XML (eXtensible Markup Language) based.

First, HTML-based electronic transactions simply receive electronic signatures on user input and process them in a server. This is because some of the input data of the transaction information, not the entire document, is processed by receiving an electronic signature. Therefore, a problem arises when a user wants to present an original signed document, which is only an exchange of user data. Therefore, legally valid transactions are not closed.

Second, in the XML-based electronic transaction, the nature of XML is the separation of the content of the document (Document Instance) and the style sheet (StyleSheet) showing the content. Therefore, to view any XML document on the Web, you must have style. In other words, the content and style of the document are managed separately. This can mean that a document's contents can appear in multiple forms (multiple styles applied). However, it can be seen that the user's digital signature on the XML electronic document is applied only to the content of the XML document. After all, this also means that when the user signs the web screen, that is, the style is not signed, there is a problem that the contents signed by the user may be displayed in different forms by the modified style.

In order to solve the above problems, the technical problem to be solved by the present invention is to process the electronic signature with the electronic signature of the contents or data of the electronic document and the style of the electronic document represented on the screen for the transaction. Its purpose is to help.

In addition, it is another object of the present invention to provide a system and method that can be legally effective only by the electronic document by processing the electronic signature of the content or data of the electronic document and the style of the electronic document at the same time.
