The present invention provides a method of selectively reproducing a CD title according to user authentication, in which each CD title is separated from the title data portion and the title head portion and selectively reproduced through user authentication, when a plurality of titles have embedded CDs. And to the system.

On the other hand, the currently released CD (compact yasc) title must be G (General audience: everyone), PG (Parental Guidance), PG-13 (13 years old and under). Parents), R (Restricted: Parents, cannot be seen under 17 without adult), and X (Adult Movie).

In order to satisfy the above criteria, most CD titles are removed from the scenes of excessive violence or adult scenes for the purpose of censorship, and are released according to the standards of each country.

Therefore, there is a desire from the perspective of viewers who watch a movie to have an original that was deleted when a CD title was purchased, but in reality, this is not the case. Some CD titles are multi-rating discs, but in reality, there is a problem that additional work must be done in the studio, which is currently rarely released.

As a method of reproducing conventional CD titles and DVD titles, Korean Patent Application No. 2002-37149 (Publication No. 2004-1826) authenticates a user by using a PKI (Public Key Infrastructure) certificate currently used at the time of title playback. In this method, the user extracts the value from the certificate, creates a rights certificate, and uses the rights information in the rights certificate to control the playback of the DVD title.

This will be described in detail with reference to FIG. 1 as follows.

First, it is determined whether to present the certificate (403), if not presented by the existing method to play (415), when presenting the certificate to determine whether the authorization certificate exists (405).

As a result of the determination, if there is an authorization certificate (once authenticated and played), the authorization and public key are extracted based on the authorization certificate (417), and playback is performed according to the authorization, and if the authorization certificate does not exist (authentication). If not received and replayed), an identity certificate is submitted to the CA server for user authentication (407). After that, if the validity of the user's identity certificate is not verified from the CA server, the process returns to the process of resubmitting the identity certificate to '407'. If the validity of the user's identity certificate is verified from the CA server, the authentication server is the database of the authentication server. The user's identity certificate (including the identity certificate signature value) and the DVD title's public key information obtained from the search are received from the CA server (409).

To check the user's age in the identity certificate, extract the social security number, generate the authority certificate using the title public key and the signature value of the identity certificate for binding (411), and play back using the generated authority certificate. (413).

When the user submits the identity certificate to the authentication server (CA) in step 407 and also includes the UPC information of the DVD title and sends it to the authentication server (CA), the certificate corresponding to the UPC rating can be received.

As described above, the present invention selects specific scenes of DVD titles released without scenes that are complicated and cumbersome, and are edited or deleted by reproducing the DVD titles using the identity certificate and the authorization certificate according to the viewer's grade. As it adopts a method of restricting viewing, it is difficult to apply in case of CD or DVD with multiple titles. Even if it is applied, multiple identity certificates and authorization certificates for multiple titles are required. As a result, many problems in application occur.

Therefore, in the case of CDs in which a plurality of CD titles are embedded, each CD title is distinguished according to the grade, and when it is desired to selectively play it, an authentication method capable of more effectively playing the title is required.

In order to solve the above problems, the present invention has been proposed. In the case of a CD in which a plurality of CD titles are embedded, each CD title is distinguished according to a grade, and when a user wants to selectively reproduce the CD titles according to the user's authentication, It is an object of the present invention to provide an authentication method and apparatus that can more effectively reproduce titles.

In order to achieve the above object, a method of selectively reproducing a plurality of CD titles includes a CD having a plurality of title data portions in a method of reproducing a CD in which a title head portion and a title data portion are separated, and the plurality of title data portions are reproduced. Is inserted into the user terminal, the web server checks the web location information stored in the CD and provides a corresponding website to the user terminal, and the web server is input from the user terminal through the website. Authentication is provided by receiving ID and password information. If authentication fails, user information including age and real name is received from the user terminal, stored in the member database, and re-authenticated. When authentication is completed, refer to the member database. A second step of issuing a personal unique authentication key; A third step of displaying, on the user terminal, a list of title data portions that can be played back using the title data portion information received from the CD based on a unique authentication key, and the web server receiving selection information from the user terminal and responding; The title header unit is transmitted to the user terminal, and the video reproducing module combines the transmitted title header unit and the title data unit, reconstructs the title into playable title, and plays the video using the video player. Receiving a connection history of the site is characterized in that the fourth step of storing in the history database.

In order to achieve the above object, a device for selectively reproducing a plurality of CD titles is divided into a title head portion and a title data portion, and in a device for reproducing a CD in which a plurality of title data portions are stored, a user ID from a user terminal. Receives a password and performs user authentication, selects a playable title list using a user authentication module for issuing a personal authentication key, a personal authentication key, and a received CD built-in title list, and a titlehead corresponding to the selected title. According to the control module and the control module for transmitting the unit to the user terminal signal generated by generating a coupon number by using the video playback module and the personal authentication key combined with the CD built-in title and the title head unit for streaming video playback to the user Coupon issuing module and sending A coupon database for storing the generated coupon number, a member database for storing the received user information, a title head database for storing a title head corresponding to the CD-embedded title, and a process used by the user to access the website are used as connection history. Characterized in that the history database to store.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is an overall configuration diagram showing a CD title playback apparatus according to the present invention.

In FIG. 2, 100 is a user terminal connected to a web server 200 via an internet communication line.

In addition, the web server 200 includes a user authentication module 210, a control module 220, a video playback module 230, a coupon issuance module 240, and a database 250.

The user authentication module 210 receives a user ID and a password from the user terminal 100 to perform user authentication, and when a user authentication is made, a user unique authentication key is issued. However, if authentication fails, the user receives age and real name from the user terminal and registers as a member through real name and age authentication of the user authentication module, and the user information is stored in the member database. After signing up, personal authentication key will be issued through user authentication.

The personal unique authentication key is associated with the member database and contains the user's personal information, which determines the user's grade as the resident registration number or the user's age. For example, since the first six digits of the social security number indicate the date of birth of the person, this calculates the age of the user.

The video playback module is responsible for combining the title data part and the title head part embedded in the CD according to the signal of the control module, and directly plays the combined title by using the streaming video playback method or separate user terminal. The video player is played to play the video.

The control module selects and displays a list of playable titles using the personal authentication key and the title data portion information embedded in the received CD. The title data portion information includes a unique number and rating information for each title. Therefore, if a grade is determined according to the age of the user in the personal authentication key, it is possible to know what titles are visible to the user of the grade with reference to the title data portion information. For example, if the user is 15 years old, a list of titles corresponding to the grades of G, PG, and PG-13 viewable at 15 years old may be selected and displayed, which is displayed on the user terminal as a list of playable titles. . When the user selects a specific title from the list of playable titles, the title head portion corresponding to the selected title is transmitted to the user terminal and played in the moving picture reproducing module. If a title other than the playable title list is selected, the control unit cannot transmit the corresponding title head unit to the user terminal, so that the title cannot be reproduced. Accordingly, the user can play only a title corresponding to his or her own unique authentication key, and a title not corresponding to the personally unique authentication key can not be played, thereby enabling selective title playback according to user authentication. In addition, the control unit tracks the process of playing the title from the user accesses the website and stores it in the history database, which is utilized for various statistical processing of the user accessing the website.

The coupon issuing module performs a function of generating a coupon number using a personal unique authentication key and transmitting the generated coupon number to a user. The type of coupon issued is different depending on the information included in the personal unique authentication key.

There are three ways to transmit the generated coupons to the user, the first is a method of transmitting the coupon number to the user wireless portable terminal in a text message via the SMS server. The second is to transmit the coupon number to the user's wireless portable terminal via the wireless Internet via a swap server. The third is to transmit the coupon number to the user wireless mobile terminal through the web server to the wired Internet. The coupon number is transmitted to the user by appropriately selecting from the above three methods.

The database is composed of a coupon database, a member database, a title head database, and a history database, which are classified for convenience according to each type of data, and the classification of the database may be variously performed.

The coupon database stores the coupon number generated by the coupon issuing module, wherein the coupon number is stored with the information of the issued member. When the coupon authentication server requests information necessary for the authentication of the coupon number, the coupon number and the member information stored in the coupon database are transmitted to authenticate the coupon number.

The member database stores the received user's personal information, so that when requesting user authentication, it is possible to authenticate whether a member is already subscribed.

The title head unit database stores the title head unit corresponding to the title data unit embedded in the CD. The title head unit can transmit the title head unit according to a control signal of the controller.

The history database stores the process of accessing and using the user from the website as the access history, and the access history corresponds to the list of titles played by the user on the website and the use time.

The SMS server 310, the swap server 320, and the web server 330 are communication servers that transmit the coupon number to the user, and transmit the coupon number to the user by wireless or wired communication, respectively.

The coupon using terminal 400 is a computer terminal that receives the coupon when the user receives the coupon, the coupon is confirmed, the coupon number delivered to the user, and transmitted to the coupon authentication server 500 .

Coupon authentication server 500 compares the received coupon number and the information stored in the coupon database to authenticate the coupon, and transmits the authentication result to the coupon using terminal 400.

Referring to the relationship between the components shown in Figure 2 as follows.

After the user logs in to the web server using the CD (①), he registers the login time and necessary information (②), and if authentication succeeds, he issues his own unique authentication key (③). The issued personally unique authentication key is transmitted to the user terminal (④), and using the authentication key, the video playback module plays the CD title (⑤), and when the playback ends, the user's connection history is stored (⑥). The coupon issuing module issues a coupon number (⑦) and transmits it to the user (⑧, ⑨). When the coupon is received at the coupon use terminal, it is transmitted to the coupon authentication module (⑩), and the coupon authentication is completed (⑪).

3 is a block diagram showing a playback principle of a CD title according to the present invention.

The internal structure of a CD title is divided into a title head portion that defines the file structure of the CD title and a title data portion containing images. The title head portion has information about the volume or the encrypted file structure. Without this information, the title data portion cannot be reproduced. Therefore, when the reproduction is prohibited, the title head portion and the title data portion are separated, and when the reproduction is necessary, the title head portion and the title data portion are combined to enable selective reproduction according to user authentication.

Therefore, in the present invention, when a plurality of title data portions are stored on the CD, the title head portion is stored separately in the web server 210, and the video reproduction module 230 is connected to the title data portion when the title is reproduced. The title head portion is combined and played.

(s20). At this time, the web location information (URL) is a URL for specifying the location of the files in each server that provides a service on the web, including the type of service to be connected, the location of the server (domain name), the location of the file, etc. do.

Through the login window of the web server, the user ID and password are received from the user terminal to perform user authentication at the website (s30). If authentication fails, the user receives the age and real name through the member registration window from the user terminal, and registers through the real name and age authentication of the user authentication module (s31, s32), and stores the authentication information in the member database and Returning to the second step is performed to log in (s33).

If the authentication is successful, it issues a unique authentication key associated with the member database (s40).

The list of playable title data sections is selected and displayed on the user terminal by using the personal authentication key and title data section information received from the CD (s50).

When receiving the selection signal of the title to be reproduced (s60), the titlehead portion of the selected title is downloaded from the web server (S70), and the titlehead portion and the title data portion embedded in the CD are combined and reconstructed into a playable title. In operation S80, the playable title is played using a video player (S90). In this case, the video playing module may use the streaming video player embedded in the website as the video player, or the video player of the user terminal may be selected and used.

Next, the access history of the website received from the user terminal is stored in a history database (s100). The access history of the website includes a list of CD titles used by the user on the website, a use time, and the like. Corresponding.

When the reproduction of the title is finished, the coupon issuing module generates a coupon number of a coupon (for example, a coupon available for a product or an online service) for using an additional service by using the received personal identification key. Store in the number database (s110), and transmits the generated coupon number to the user (s120). As a transmission method, a method of transmitting the coupon number to a user's wireless mobile terminal through a SMS message through a SMS server, a method of transmitting the coupon number to a user's wireless portable terminal via a wireless internet via a swap server, and a web, There is a method for transmitting the coupon number to the user terminal via the server to the wired Internet.

When the coupon authentication server receives a coupon number from a coupon use terminal (for example, a wireless portable terminal or a user terminal), that is, when a user requests authentication from the coupon authentication server to use a coupon issued upon termination of the title, The coupon authentication server searches the coupon number database of the web server and authenticates the coupon number received from the coupon use terminal, and the coupon authentication server sends a completion signal for coupon authentication to the coupon use terminal, Complete the authentication step (s130).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary skill.

As described above, the present invention provides a method and system for selectively reproducing a CD title according to user authentication, in which each CD title is separated from the title data portion and the title head portion and selectively reproduces the title through user authentication. CD titles can be selectively played according to the user's authentication while the titles are classified according to their ratings.
