In the past, the main distribution method for content such as albums and movies was to store files embodying the content on storage media such as CDs and tapes, and trade the storage media offline. At this time, while producing the entire album, the artist's emotional code was incorporated into it, and the creative intention of the producer and artist who produces and sells the music was clearly expressed. In particular, consumers who demand content were able to receive not only the music included in the album, but also the album's jacket photo, production intention, production episodes, and the artist's pictorial.

However, thanks to the rapid development of wireless communication and its equipment, the distribution method of providing media content has now moved to online communication networks. In other words, users subscribe to an online content service, receive music and other content streamed online through their smartphones, and listen to the music or watch the video. However, as online content services became widespread, the emotional satisfaction that could be felt in the past by purchasing CDs or tapes offline and owning the entire album could no longer be satisfied, and it became difficult to clearly communicate production intentions.

In addition, recently, in addition to content such as albums, various artist-related products or goods are being sold, so there is a demand for offline content services for these goods as well.

Hereinafter, specific details for implementing the present invention will be described with reference to the drawings.

In addition, in explaining the present invention, like parts are given the same reference numerals, and repeated description thereof is omitted.

First, examples of the configuration of the overall system for implementing the present invention will be described with reference to FIG. 1.

As shown in Figure 1, the mobile-based content service system for online and offline distribution (hereinafter referred to as service system) according to the present invention is installed on a content authentication medium 10 that stores authentication information of the content and a mobile terminal 20. It consists of a service system 30 and a content server 50 that provides content online. Additionally, it may further include a database 40 that stores data such as content, or a network 80 that connects the mobile terminal 20 and the content server 50.

First, the content authentication medium 10 is equipped with a short-distance communication module. The short-distance communication module stores content playback information and authentication information for the content product.

The content playback information stores the ID or location information of the content. In particular, the content playback information may include playback information that allows access to the content server 50 to play specific multimedia content, for example, URL (Uniform Resource Locator) information.

Additionally, the authentication information is authentication information for the content product, and once the authentication information is confirmed (verified), the content can be played. In other words, the authentication information is authority information that permits playback of the corresponding content.

Preferably, the short-range communication module may be a module capable of short-range wireless communication, such as a Near Field Communication (NFC) tag or an RFID tag, especially a passive module. Additionally, the short-distance communication module may use a code detected by optics, such as a barcode or QR code. The short-distance communication module is not limited to specific examples, and any module (or passive module) capable of short-distance communication is applicable.

Meanwhile, the content authentication medium 10 may be implemented in the size or shape of a credit card, coin, etc. Or, as another example, the content authentication medium 10 may be implemented by being attached to goods, products, etc. For example, the content authentication medium 10 may be buried and installed within a goods product such as a doll.

Next, the mobile terminal 20 is a mobile terminal such as a smartphone or tablet PC, and is a terminal in which a program can be installed and executed. Additionally, the mobile terminal 20 may be a dedicated terminal that has a dedicated program installed, such as an iPod, and plays content.

In addition, the mobile terminal 20 is equipped with a short-range wireless communication function that can read NFC tags, RFID tags, etc., or is equipped with a function that can optically scan barcodes, QR codes, etc., such as with a camera. This function will be called a short-distance communication function.

In addition, the mobile terminal 20 is equipped with a wired or wireless communication function capable of communicating with the content server 50 and the network 80.

Next, the service system 30 is a mobile program (or application, app, etc.) or a dedicated program installed on the mobile terminal 20, and verifies authentication information and plays content.

In particular, the service system 30 connects to the content server 50 and receives and stores the authentication information group.

Additionally, the service system 30 connects to the content server 50 to receive and store content, receive streaming content online, and play the received or streamed content.

Additionally, the service system 30 reads the content reproduction information and authentication information of the content authentication medium 10 through the short-distance communication function of the mobile terminal 20. Then, the service system 30 verifies (authenticates) the read authentication information by comparing it with the authentication information group, and when confirmed, plays the corresponding content.

Next, the content server 50 provides content and authentication information or authentication information group for the content. In particular, the content server 50 provides content services in conjunction with the service system 30 installed in the mobile terminal 20.

In particular, the content server 50 provides content, downloads it for storage, or provides the content in real time through streaming.

Content includes digital media data such as voice, sound source, video (or video), and text data.

Additionally, content may be provided in a form consisting of multiple contents, that is, in the form of an album. For example, a content album may consist of multiple sound sources, such as seven. Additionally, a content album may consist of 7 sound sources, 3 music videos, an album description document, etc. In other words, a content album may be composed of multiple contents and multiple types of content.

Additionally, the content server 50 may download authentication information for the content and store it in advance in the mobile terminal 20 or the service system 30. In particular, authentication information is downloaded in groups. Therefore, the content server 50 is configured to download authentication information to each mobile terminal 20 or service system 30 rather than directly performing authentication for the content.

Next, a mobile-based content service system 30 for online and offline distribution according to an embodiment of the present invention will be described with reference to FIG. 2. As previously described in FIG. 1, the content service system 30 according to the present invention is implemented as a program system 30 installed in the mobile terminal 20.

As shown in Figure 2, the mobile-based content service system for online and offline distribution according to the present invention includes an authentication group storage unit 31 that downloads the authentication information group from the content server 50, and a content authentication medium 10. An authentication information acquisition unit 32 for acquiring authentication information, an authentication result transmission unit 33 for transmitting the authentication result to the content server 50, a content reception unit 34 for receiving content from the content server 50, and, It consists of a content playback unit 35 that plays content once authenticated. Additionally, it may be configured to further include a data storage unit 38 for storing data.

First, the authentication group storage unit 31 downloads the authentication information group from the content server 50.

That is, the authentication group storage unit 31 connects to the content server 50 and provides playback information such as produced/released media information, overall production information of the content, or location information of the content, and authentication information of the content. Download to the mobile terminal 10 in advance. The downloaded playback information and authentication information are stored in the data storage unit 38.

Additionally, the authentication group storage unit 31 continuously updates authentication information. As an example, the content server 50 is periodically accessed to continuously update authentication information through installation and updates of application software.

Additionally, the authentication information in the media/content production list is hashed or encrypted into bytes of a specific length and downloaded. Preferably, data of the authentication information group and hash data of the corresponding authentication information group are transmitted together. These are used for integrity verification. Additionally, authentication information group data (and hash data) may be encrypted and transmitted.

In particular, the authentication group storage unit 31 receives and stores authentication information in groups.

Authentication information groups can be set by the user. In other words, groups of serviceable media and content authentication information can be selectively downloaded according to the user's preference. As an example, when installing application software, a group (or preference group) of authentication information to be downloaded may be selected through a procedure to confirm the user's preferences. Additionally, users can set or change their preference groups midway. Additionally, downloading of media and content can be applied only to products scheduled to be purchased or to all services depending on the user's selection.

That is, in the process of installing the client application for media and content services, that is, the service system 30, the authentication information of the content is downloaded in advance. Additionally, when new media and content are produced/released, authentication information is downloaded (updated) manually or automatically (with user selection) and stored in the mobile terminal 20 or the data storage unit 38.

A group of authentication information can be set based on criteria for classifying content. For example, it can be set according to release date, media type, artist, agency, album, etc. In addition, it may be set according to standards for classifying content, etc.

Based on the release date, each content (or content's authentication information) can be classified by year, month, or specific period by dividing the release date into a period.

In the case of music, content types can be classified (grouped) according to music genre, such as ballad, dance, rap/hip-hop, R&B/soul, indie, rock/metal, trot, and folk/blues. Additionally, in the case of videos, content types can be classified according to video genre, such as comedy, drama, romance, action, thriller, science fiction, and music video. Additionally, content types can be classified according to region. For example, it can be classified into the United States, Korea, foreign countries, etc.

Additionally, they can be grouped according to artist. A specific artist can be designated, or it can be designated by the artist's age/gender, etc.

Additionally, artists can be grouped based on their agency. For example, agency A's group can be composed of all content released by that agency.

Additionally, albums can also be grouped as a criterion. In other words, one album may consist of multiple contents. For example, you can set this year's Hot 100 albums and group the top 100 songs, videos, music videos, etc. from that year. Additionally, all authentication information for the album can be bundled, and authentication information can be individually authenticated for each content within the album. As another example, assuming a platform album as a media data product, the release list of all platform albums released by a specific artist corresponds to the authentication information group.

Additionally, when setting up a group, you can set the group by combining multiple criteria. For example, you can set a detailed combination by combining multiple criteria, such as Korea/Artist in his 20s/Hip Hop, etc. At this time, the combination of criteria may be composed of a combination using a logical operation (boolean).

Meanwhile, the content server 50 defines and stores metadata for each content product. In other words, for newly released products, whether or not they are included in the authentication information group is defined as metadata according to the product's attributes and then stored. An example of the form of metadata for creating a group of authentication information is shown in the table in FIG. 3. Metadata can be added depending on the characteristics of the product.

Various groups can be created according to each content of metadata. By the authentication group storage unit 31, authentication information for the group that meets the conditions selected when installing application software or when the user specifies an option is downloaded to the mobile terminal 20 or the data storage unit 38. For example, if a user selects a female 4-member ballad music group, the authentication information for the artists corresponding to the metadata with metadata number 3 having a value of 1, number 7 having a value of 1, and number 8 having a value of 4 is provided. It is downloaded. Or, if you want products for all artists of RBW's agency, authentication information for metadata where item 6 of the metadata is 1 is downloaded.

Meanwhile, when the authentication information group is downloaded from the content server 50, authentication information for all products produced and released is not downloaded. Instead, only the authentication information that allows the purchase of products based on the time the user installs the application software is downloaded. Additionally, purchases and authentication made by other users that cannot be authenticated by other users are also excluded from the authentication information. Therefore, authentication information shrinks as time passes. Additionally, even when sales of a product are discontinued, the authentication information for the corresponding product is removed from the content server 50 and reflected when updating the authentication information.

Additionally, a processing method for transmitting authentication information to the mobile terminal 20 uses a hash function. In other words, it is used to check the integrity of the data of the authentication information stored in the mobile terminal 20 or the data storage unit 38 in case of damage, damage, manipulation, modification, etc. In other words, the data of the transmitted authentication information or authentication information group is transmitted along with the hash of the corresponding data, and the hash data is used for integrity verification.

Next, the authentication information acquisition unit 32 obtains authentication information from the content authentication medium 10 and verifies the authentication information by referring to the authentication information group. In other words, it is checked whether the acquired authentication information is registered in the authentication information group.

As described above, the content authentication medium 10 is equipped with a short-range communication module, and content playback information and authentication information for the content are stored in the short-range communication module. At this time, the short-range communication module may be a module capable of short-range wireless communication, such as an NFC tag or RFID tag, especially a passive module. Additionally, the short-distance communication module may use a code detected by optics, such as a barcode or QR code.

That is, the user obtains authentication information from the content authentication medium 10 using the short-range wireless communication function or the optical function of the camera through the mobile terminal 20. That is, user authentication is performed in the mobile terminal 20 using methods such as wireless or camera recognition. For example, in the case of wireless, product information (or authentication information) is transmitted through a wireless connection between the mobile terminal 20 and the content authentication medium 10, such as short-distance wireless communication such as NFC. Then, the user is authenticated by comparing the authentication information of the media and content stored in the mobile terminal 20 or the information in the authentication information group.

The authentication method of the purchased product or content is shown in Figure 4. In other words, the obtained authentication information (or product authentication information) is compared with the authentication information in each authentication information group to check whether there is a match.

The authentication information acquisition unit 32 compares the hash data (stored authentication information group data) of information obtained from the content authentication medium 10, such as the purchased product, to determine whether the purchased product (or content authentication medium) is a normal product. Check the integrity of

Specifically, as shown in Figure 5, the integrity of the stored authentication information or authentication information group is confirmed, and the integrity is confirmed through hash comparison between the obtained authentication information and the stored authentication information. After the two types of integrity are verified in this way, the data is compared between the authentication information extracted from the product information (or content authentication medium 10) and the authentication information downloaded from the content server 50 and stored in the mobile terminal 20. . Through this, the authentication process proceeds on the mobile terminal 20. If there is matching information between the two pieces of information, authentication is confirmed and media and content services are provided. Additionally, if there is no matching information, the service is not provided.

In particular, the primary integrity verification hashes the authentication information data transmitted from the content server 50 and compares the hashed data with the hashed data transmitted from the server. As shown in Figure 5, the content server 50 generates hash data by hashing the original data of the authentication information, and transmits the encrypted authentication information and the hash data together to the mobile terminal 20. Then, the authentication information transmitted from the mobile terminal 20 is hashed to generate hash data, and the generated hash data is compared with the received hash data. And if they match, it is considered that the integrity verification has passed.

In addition, the secondary integrity verification creates hash data by hashing the authentication information obtained from the content authentication medium 10 of products and services, and verifies the integrity by comparing the generated hash data with the hash data transmitted from the server. .

Since authentication for product purchase is performed on the user's mobile terminal 20, it has the advantage that the mobile terminal 20 does not necessarily have to be online. In other words, even in an environment where online connection is difficult for the mobile terminal 20 (service shadow area, overseas, service unavailable area, etc.), user authentication for product purchase is possible and immediate service of media and content is possible.

In particular, the authentication information acquisition unit 32 obtains authentication information from the content authentication medium 10 while not connected to the content server 50 and performs verification by referring to a pre-stored authentication information group.

Next, the authentication result transmission unit 33 transmits the authentication result to the content server 50.

Once the content product is authenticated, the user authentication (or authentication of the product) result is transmitted to the content server 50 when online.

At this time, the content server 50 updates authentication information and group information of the sold product. That is, the content server 50 excludes the authentication information of content that has already been authenticated from the authentication information group. In other words, items that cannot be authenticated by other users due to purchases and authentication made by other users are also excluded from the authentication information group. Therefore, authentication information shrinks as time passes. After the authentication information for already sold and certified products is removed from the content server 50, it is reflected when updating the authentication information in the mobile terminal 20.

Additionally, the authentication result transmission unit 33 may transmit information that has not been authenticated to the content server 50 according to the user's intention.

Next, the content receiving unit 34 receives content from the content server 50.

The content receiving unit 34 can download content in advance. In other words, if the user has downloaded all production/release information and media/content in advance, offline authentication and offline media/content services are immediately possible.

In addition, if data for media/content has not been downloaded in advance, immediate download occurs when online access is available at the mobile terminal 20, and services for media and content are possible.

Next, the content playback unit 35 plays the content once authenticated.

In other words, if the content is downloaded and authentication for the content is completed (passed), the content can be played. Preferably, it is played upon user's command. Or, in another embodiment, if authentication information is obtained from the content authentication medium 10 and authenticated, the corresponding content can be played immediately.

Next, the product authentication process in terms of a content server and a mobile terminal according to an embodiment of the present invention will be described with reference to FIG. 6.

As shown in FIG. 6, first, when content products and services are produced/released in the content server 50 (S1), authentication information for the products and services of the content is generated (S2). Then, metadata for authentication information for the content is created, and authentication information groups are grouped and created (updated) according to the metadata (S3).

Next, the content server 50 hashes the authentication information group to be transmitted and performs encryption (S4). The encrypted authentication information group data and hash data are transmitted to the mobile terminal 20 and stored in advance.

Next, the service system 30 is installed in the mobile terminal 20 (S5). The application software of the service system may be installed in advance.

Next, the mobile terminal 20 obtains reproduction information and authentication information from the content authentication medium 10 of the product or service (S6).

Next, the authentication information (and reproduction information) of the obtained product/service is hashed (S7). At this time, the encrypted and transmitted authentication information group is decrypted (S8). Then, the hash values of the authentication information are compared to verify the integrity (S9). As previously explained, integrity verification consists of primary verification, which hashes the transmitted authentication information and compares it with the received hash value, and secondary verification, which hashes the obtained authentication information and compares it with the received hash data.

Next, authentication of products and services is performed by comparing the transmitted and pre-stored authentication information group with the acquired authentication information (S10). And when authentication passes, the content of the corresponding product or service is activated (S11).

Next, the mobile terminal 20 transmits the authentication result to the content server 50 (S12). At this time, the content server 50 updates the authentication information group by reflecting the authentication result (S13).

Above, the invention made by the present inventor has been described in detail according to the above-mentioned embodiments, but the present invention is not limited to the above-described embodiments, and of course can be changed in various ways without departing from the gist of the invention.
