Description

{Creative Method and Active Viewing Method for A Electronic Document}

The present invention relates to a method for creating and reading an electronic document, extracting image data and text data for a document from an electronic document created by existing general-purpose commercial software, and generating the electronic document in a format suitable for the practice of the present invention. Its purpose is to provide a way for clients to view it.

Conventionally, there are electronic document formats such as "Word", "Excel", "PowerPoint" of Microsoft Corporation, and "Hangul" of Korean and Computer Corporation. These electronic documents are basically text documents, and employ a method of processing character information into text data. However, since such information is processed as text data in order to be able to continue editing in any system, the display form is dependent on the environment of the system in which the document is opened.

On the other hand, a document format that maintains the form of the document regardless of the system environment is Acrobat's "PDF" file format. This file format is designed to maintain the initial editing status of documents on different platforms during the distribution of documents. This file format is not related to the existence of specific fonts and maintains the same document format on different operating systems. There is an advantage.

However, when the PDF file format is distributed online, the structure of the document is complicated and the size of the viewer program is large. Therefore, the PDF file format has a problem in that it takes a long time from the request point to view the document.

According to the present invention, there is provided a method for converting various original electronic documents or original images so that they can be viewed independently on a platform in an on / offline environment, and a document format supporting the same.

And, and provides a customer response analysis method for analyzing the reading status of the client using the electronic document comprising the step of analyzing the transmitted data.

The following is a description of terms used in the description of the present invention.

SDF: Streaming Document Format invented in the present invention

Constructor: the creator of the SDF document

SDF Viewer: Software that runs on the viewer's platform and enables the viewing of SDF documents. The SDF document is linked to the SDF document format, and any SDF document called will be called through the SDF viewer. In addition, the SDF viewer is plugged into the Internet browser running on the platform, so that the SDF document can be viewed through the browser. The SDF viewer has a form of opening and reading a real book.

Viewer, User: A person who browses the SDF document created by the creator through online / offline.

Online: When accessing SDF documents through the general Internet or a specific data network.

Offline: When a viewer accesses and browses SDF documents stored in the storage device of the platform he is using.

Platform: Computers and operating systems used by the creator or viewer

Dynamic Viewing: Allows the user to immediately view the desired page on the SDF document on / offline, or to view any page other than the first page when the SDF document is first viewed by a particular setting. Enable

Streaming: Send data for dynamic viewing on-line

Page: One side of the document to be viewed

Hereinafter, a detailed configuration of the present invention will be described with reference to the accompanying drawings.

The present invention consists of two parts. Encoding the original document to generate an SDF document file, and viewing the SDF document file on / offline.

First, the step of generating an SDF document file by encoding an original document will be described in detail with reference to FIG. 1.

In step 1 of FIG. 1, the following information is automatically or manually input by the user.

(1) Security-related items: viewer scope, service scope (online, offline, service server limitation, reader platform limitation, password setting, encryption algorithm selection, printing support, screen copying availability

(2) Copyright-related items: Author information, designation of the handling method when the viewer is not permitted by the security setting (document deletion, automatic movement to the specified URL, warning message designation)

(3) User response analysis related items: Whether to use user response analysis related to the technology of Patent No. 0456438, setting elements required for reaction analysis, response analysis server address, range of user response analysis items

Step 2 is generally used to obtain the original document and should be printable.

Step 3 is a step of converting the original document into a file in a platform independent form, using a plug-in or a standalone conversion software.

Steps 4 and 5 analyze the file after the neutral formatting process to determine and generate the data structure of the SDF file in a format suitable for the type of original document.

Steps 6 to 8 extract the characters contained in the original document from the neutral file generated in step 3. If the original document is a text format, the text is extracted directly from the neutral document. Extract the characters through the process. In this process, the coordinate value and relative size of the position of the character in the document are calculated and databased in pairs.

Steps 9 to 11 are the steps of converting the neutral file generated in step 3 into standard data in order to provide platform independence while maintaining the original configuration. The data is analyzed through the data optimization process by analyzing the characteristics of each page. The process of reducing the size of the system is included. In the case of the image data, the palette is generated through the three-dimensional optimization process for the color space in the data optimization process and automatically converted into the appropriate image compression format according to the characteristics of the palette.

Steps 12 and 13 calculate the interrelated information of the data created in steps 8 and 11 to configure the data format that can be viewed and streamed dynamically. Generating meta data is included.

Steps 14 and 15 are steps of synthesizing data generated in each of steps 13, 8, and 11 through an encryption process to finally generate an SDF document. In this case, encryption uses the encryption method specified by the creator in step 1.

Tasks in steps 1 to 15 of FIG. 1 may be processed offline by client-only software, but may also be provided as a web service.

Next, the steps of viewing the SDF document file on / offline will be described in detail with reference to FIG. 2.

In step 17 of FIG. 2, if the SDF viewer capable of decoding the SDF document is installed on the viewer's platform or automatically installed on / off line, the SDF viewer reads the meta data of the SDF document first.

In step 18, the SDF viewer analyzes only the data related to security and reading conditions from the meter data read in step 17 and checks whether the current viewing situation satisfies the security and reading conditions specified by the creator. At this stage, if the inspection turns out to be inadequate, the SDF viewer performs the processing steps specified by the creator. If it is found to be suitable, the SDF viewer sets the environment according to the viewing conditions and proceeds to step 19.

In step 19, the SDF viewer analyzes data related to the page data structure from the meter data read in step 17 to create a condition capable of dynamic viewing. At this time, the data for searching is read first from the page data.

 Steps 20 and 21 are the steps of initially reading the specific page data set by the first page or creator in a streaming manner, and then reading any page data requested by the user. In this case, when viewing the SDF document online, the SDF viewer continuously performs steps 20 and 22 to 25 as background operations unless the data of the front and rear pages of the currently viewed page is not read from the SDF document.

In step 22, the page data read in step 20 is decoded and restored to the data of steps 8 and 11.

Step 23 is a step of generating an image by decoding the image data in the page data reconstructed in step 22 according to the image compression algorithm used.

Steps 24 and 25 are steps of calculating and displaying the coordinates in the page based on the result calculated in step 7, in the page data restored through step 22. At this time, in order to display the location of the search result when the viewer searches, the character and coordinate calculation data are maintained in a recyclable state.

In step 26, the SDF viewer integrates the results generated in steps 23 and 25 and displays them on the screen of the viewer platform.

In step 27, when the request of the viewer in step 21 is an enlargement / reduction / move / link in the page being viewed, the step proceeds to step 26 by constructing a screen suitable for the viewer's fairy without performing steps 22 to 25. to be..

Step 28 shows the behavior of the viewer's request in Step 21 and the status of the input devices (mouse, keyboard, etc.) operating on the platform. A step of processing the viewer's response analysis using the technique of Patent No. 0456438.

By providing the present invention, it is unsuitable for the web service of the existing general-purpose electronic document (e.g., PDF): when the amount of documents increases or the network bandwidth is limited, the loading time becomes long,

 Maintain original font / editing form, which is a problem of existing web documents, and original font / editing form, and problem of existing image-based e-book format, random access is possible, but it cannot process font information It is possible to overcome problems such as limitations in web services depending on the specific platform.
