Abstract

An e-book is provided to prevent users from copying the e-book illegally while restricting thoughtless use by including user authentication information such as available expiration information, available playback count information, and terminal authentication information. An e-book(100) is executed in a user terminal, and includes data(110) and user authentication information(114). The user authentication information restricts usage of the e-book and prevents other terminals from executing the e-book. The user authentication information includes available expiration information(104) for restricting a use period, available playback count information(106) for restricting an execution count, and terminal authentication information(108) for checking whether the terminal for executing the e-book downloads the e-book to be executed. The available playback count information is updated by decreasing the execution count by one in every execution.

The present invention relates to an e-book, and more particularly, to an e-book provided to suppress indiscriminate use and illegal copying.

Recently, due to the development of computer and communication network technology, the digital contents industry using them is prevalent.

Digital content refers to all intangible information distributed online, such as e-books and multimedia (images, music, videos, games, etc.). It is based on the nature of digital content itself. Disks) to easily copy and distribute the data.

Due to the nature of digital content, illegal copying of digital content has been popular in recent years, and each digital content producer has been making various efforts such as introducing a membership system or installing an anti-piracy device to prevent this. However, these methods cannot fundamentally prevent the dissemination of digital contents due to the recent piracy.

As a result, digital content producers lose their motivation to produce content and suffer a lot of economic losses. As a result, the digital content business, which is gaining worldwide attention, is shrinking.

In the case of multimedia, among the various digital contents, many protection devices have been developed by record producers and film producers, but in the case of e-books, such protection devices are rarely developed.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is to provide an e-book provided to suppress indiscriminate use and illegal copying.

In order to achieve the above object, the e-book according to the present invention is an e-book in the form of digital content executed through a user terminal, including data containing a book content consisting of text, and the degree of execution by the user and different from the terminal. Characterized in that it comprises a user authentication information for restricting execution in the terminal.

And the user authentication information is valid period information for limiting the expiration date; Valid play count information for limiting the number of executable times; And terminal authentication information for checking whether the terminal to be executed is the terminal which downloaded the e-book.

In addition, the effective replay count information is characterized in that it is updated to decrease by one count at each execution.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The e-book 100 according to the present embodiment is a kind of digital content, as shown in FIG. 1, and includes data including a header 102 and an end of file (EOF) 112, and a book content composed of text. ).

In particular, the e-book 100 according to the present embodiment includes a user authentication information 114 for regulating the degree of execution by the user and limiting the execution of the terminal and the other terminal, which is the e-book 100 Its purpose is to curb indiscriminate use and piracy.

The user authentication information 114 is valid period information 104 for limiting the expiration date, valid play count information 106 for limiting the number of times of execution, and whether the terminal to be executed is the terminal that has downloaded the e-book. Terminal authentication information 108 for checking whether or not to include.

Therefore, the e-book 100 having the user authentication information 114 may be executed only for a predetermined period of time in the state of being downloaded and stored in the user's terminal through the expiration date information 104 and the effective replay count information 106. In addition, as the number of times of play is limited within a certain period, indiscriminate use by the user is suppressed, thereby increasing the value of use.

In this case, the effective replay count information 106 of the user authentication information 114 is updated to decrease by one count at every execution in a state where the effective replay count information 106 is initially set to a predetermined number of times.

In addition, the user authentication information (114) of the terminal authentication information (108) is whether the terminal to execute the e-book (100) whether the e-book (100) downloaded from the web whether the e-book (100) The e-book is executed only in the terminal that has downloaded the illegal copying of the e-book 100 to be useless.

Next, the process of using the e-book 100 will be described in detail with reference to FIG. 2.

2 is a flow chart sequentially illustrating a process of using an e-book according to the present invention.

As shown in FIG. 2, in an initial step 201, the e-book provider may include valid period information 104, valid reproduction count information 106, and terminal authentication information 108 in data 110 including text of a book. Add to generate the e-book 100 file, and in step 202, the e-book 100 file generated as described above is uploaded to the web.

Thereafter, in step 203, the user searches for the desired e-book 100 file on the web, and in step 204 pays for the desired e-book 100 and downloads it to his terminal.

Subsequently, the user inputs an execution command of the e-book 100 file of his terminal in step 205. Then, in step 206, the user terminal checks the user authentication information 114 in the terminal.

If the validity period information 104, the effective playback count 106 and the terminal authentication information 108 is confirmed to be valid, the process proceeds directly to step 207 and the e-book 100 file is executed through the user's terminal. In this state, as the user inputs the e-book 100 file termination command to the terminal (step 208), the executed e-book 100 file can be terminated.

On the other hand, if any one of the three user authentication information 114 is not satisfied in step 206, the process proceeds to step 209 instead of step 207. In step 209, the user authentication information 114 is displayed through the display unit of the terminal. An invalid reason is displayed and the entire process is ended as the execution of the e-book 100 file is rejected.

As described in detail above, the e-book according to the present invention has user identification information such as valid period information, valid play count information, and terminal authentication information, thereby preventing illegal duplication while preventing indiscriminate use by the user. It can increase the value of use.
