Post-Digital Rights Management Assignment Apparatus and Method

The present invention relates to an apparatus and method for allocating post digital rights management, and more particularly, to an apparatus and method for allocating post digital rights management (DRM) to be applied after an e-book is published. .

An e-book refers to an electronic publication that has processed and stored contents such as textbooks, books, exam papers, workbooks, and language semesters in a digital form that are used in daily life. The market is growing rapidly due to development.

The standardization of e-book format, centered on the US and European markets, formed the International Digital Publishing Forum (IDPF) with book distributors, e-book solution companies, and publishers centered, and IDPF is an XML-based e-book technology. A standard ePUB (Electronic Publication) standard was developed.

ePUB is widely used as a de facto e-book standard in overseas markets such as the United States and Europe, and in the North American market, most e-book providers distribute e-books in ePUB file format. In addition, in line with this trend, most domestic publishers are producing e-books in ePUB format.

However, although the ePUB market is revitalized, there is a problem in that it is difficult for a publisher who has published a traditional book or an individual who has contents to produce and publish an ePUB e-book.

For this reason, publishers or individuals are producing ePUB e-books using e-book production tools distributed free of charge by distributors, but there is still a problem that users are difficult to handle with this e-book production tool.

These problems are acting as a barrier to the activation of the ePUB market.

Therefore, it is necessary to develop a technology to increase post traceability by assigning DRM, which can be applied after the e-book is published, to check the log of file use.

Therefore, the present invention has been proposed to solve the above problems, and it assigns a post-digital rights management (DRM) that can be applied after the e-book is published to check the log of the file use, so that the follow-up tracking It is to provide a post-digital rights management assignment device and method to increase performance.

1 is a diagram for explaining a series of processes in which an e-book to which post-digital rights management is assigned is provided and applied according to an embodiment of the present invention.

After the distributor converts the e-book 10 to which the post-DRM is assigned through the distributor terminal 100 and uploads it to the server 200, at least one user uploads the uploaded e-book 10 to the user terminal ( 300) to download it.

In the text (vector image) included in the e-book 10, several numbers are assigned to each letter, and there is a decimal point of a certain length after it. Post-DRM can be assigned to each vector data constituting the text.

For example, in order to prepare for a case where one text character is enlarged, data is input only to the first two digits out of six decimal places, and post-DRM is assigned to the remaining four digits. Alternatively, post-DRM may be assigned to only one of the remaining four digits. That is, post DRM may be allocated to some or all of the remaining digits, which can be set and changed as needed.

That is, post-DRM may include numbers, time, watermark graphics, and traceable information through a combination of the remaining digits.

Each user outputs and displays the downloaded e-book 10 through his/her user terminal 300. At this time, when the e-book 10 is displayed, the elapsed time by checking the initial download time and the current time is extracted, and a visual effect corresponding to the extracted elapsed time based on the post-DRM assigned to the e-book is given.

As described above, in the present invention, it is possible to maintain the standard data format while maintaining the original by allocating post-DRM to each vector data rather than inserting additional DRM.

2 is a block diagram showing the configuration of a post digital rights management assignment device according to an embodiment of the present invention, wherein the post digital rights management assignment device may be the distributor terminal 100 .

First, the distributor converts an electronic document including text information and raster image information into an e-book 10 through the distributor terminal 100, and in this conversion process, post-DRM is allocated and included as post-DRM information. Hereinafter, a detailed configuration of the distributor terminal 100 for converting an electronic document into an electronic book and allocating post-DRM will be described with reference to FIG. 2 .

Referring to FIG. 2 , the distributor terminal 100 includes an input unit 101 , an extraction unit 103 , a conversion unit 105 , a storage unit 107 , a transcoding unit 109 , and a control unit 111 .

The input unit 101 receives an electronic document from the distributor. In this case, the electronic document may be a file in the form of HWP, MS Word, or PDF including text information and raster image information.

The extraction unit 103 extracts at least one piece of information about text information and raster image information included in the electronic document. In this case, the at least one piece of information may be coordinate information, layout information, attribute information, or the like.

The conversion unit 105 converts text information included in the electronic document into a vector image and extracts a raster image. In addition, by matching coordinate information, layout information, attribute information, and text information corresponding to the vector image, and allocating post-DRM information to each vector data constituting the vector image, meta information (meta) is generated. Here, the meta information may include coordinate information of a vector image, coordinate information of a raster image, layout information of original content, attribute information on a text font, and the like. In addition, post-DRM information may be set or changed by the distributor as information that can be tracked and logged, or may be preset.

The storage unit 107 stores the vector image and the extracted raster image converted by the conversion unit 105, and stores the generated meta information.

The transcoding unit 109 transcodes the vector image and the raster image stored in the storage unit 107 into an e-book including meta information in one format (package).

When receiving an electronic document from the distributor, the control unit 111 controls to extract coordinate information, layout information, and attribute information for text information and raster image information included in the electronic document. Thereafter, this text information is converted into a vector image, the raster image is extracted and stored, and coordinate information, layout information, attribute information, and text information corresponding to the converted vector image are matched, and for each vector data constituting the vector image Control to generate and store meta information (meta) by allocating post-DRM information. In addition, it controls to transcode the stored vector image, raster image, and meta information into an e-book including one format.

When the input unit 101 receives an electronic document from the distributor (S401), the extraction unit 103 extracts coordinate information, layout information, and attribute information for text information and raster image information included in the electronic document (S403) .

Thereafter, the conversion unit 105 converts the text information into a vector image, extracts the raster image, and stores it in the storage unit 107 ( S405 ). In addition, the conversion unit 105 matches coordinate information, layout information, attribute information, and text information corresponding to the converted vector image, and allocates post-DRM information to each vector data constituting the vector image to generate meta information (meta). generated and stored in the storage unit 107 (S407).

The transcoding unit 109 generates an e-book by transcoding the vector image, raster image, and meta information stored in the storage unit 10 into an e-book in one format (S409).

From the server 200 to which the post-DRM-allocated e-book generated through the distributor terminal 100 is uploaded, the user receives it through the user terminal 300, and the user terminal 300 first downloads the e-book. The elapsed time point is extracted from the time point, and a visual effect corresponding to the elapsed time point is given.

Referring to FIG. 4 , when the elapsed time has passed a preset time, a visual effect of an old feeling may be given to express it so that it feels like an old book, although it is not an actual book.

In addition, for example, when forgery or falsification is confirmed based on a period, number of times, or a user, a visual warning effect such as a color, a symbol, a text, etc. may be provided.

5 is a diagram illustrating an example of a structure of an SVG vector format.

Referring to FIG. 5 , Scalable Vector Graphics (SVG) is a vector format for creating high-quality interactive web graphics, and uses only two digits among numbers constituting path information of a vector graphic displayed in green.

Therefore, all six digits of the standard are not used, and the present invention can generate and track DRM information using the unused decimal places.

In addition, in the case of three decimal places or less, if the content is not magnified by more than 1000 times, it is difficult for the user to distinguish the difference between the contents with the naked eye, and a unique fingerprint such as a seal is formed so that the original can be collated or traced later.

In the present specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms are used, these are only used in a general sense to easily explain the technical content of the present invention and help the understanding of the present invention. It is not intended to limit the scope.
