The present invention relates to updating of data, and more particularly, to a method for updating advertisement data in an advertisement output device and an apparatus for updating the same.

Countless commercials are broadcast on television. Some of these advertisements impress viewers and help them sell their products for a long time, while most of them are ineffective and are being pushed out of the viewers' attention and replaced by new ones. Despite such large and small deviations in advertising effectiveness, advertising on television is costly and puts an economic burden on advertisers.

In order to broadcast commercials through a conventional television, it has to be expensive because it requires a request to a broadcasting station or a cable broadcasting station. Moreover, since the advertisement must be newly produced in order to export the advertisement with new contents, the funds invested in the advertisement will increase exponentially. Therefore, advertisers are demanding a new method of advertising that can provide more efficient advertising by advertising in a state of high concentration of viewers at low cost through television.

In particular, an Internet TV set-top box that enables internet communication in a television has been popularized. However, when using an internet communication, an advertisement is not output unlike a television, which is a blind spot of an advertisement. Of course, the advertisement may be displayed on the web page, but the server operator providing each web page includes its own advertisement content. Therefore, advertisers paying huge advertising fees and sending advertisements to television have a problem that the commercials are not output during the Internet use time, which is a complaint due to the deterioration of the advertising effect.

As a niche market for such advertisements, advertisements using the OSD (On Screen Display) function have been developed. That is, an advertisement (for example, an image such as a specific advertisement logo, a video, or a text) by an OSD function is displayed on one side of the screen of the television. Of course, the advertisement data according to the displayed advertisement is stored in a storage means of a type provided or combined in the television, and the television extracts the corresponding advertisement data and displays it on the screen. There is an advantage that can achieve a high advertising effect by drastically discounting the selling price for the television including such an advertising function and inducing to watch the advertisement.

The advertisement data should be updated from time to time. The updating methods include a method of transmitting advertisement data to a corresponding television device through a wireless network and a method of directly transmitting and updating advertisement data to a television device using a wired or short-range wireless communication. This can be.

However, unauthorized advertisements that are not related to the advertiser that requested the advertisement may be updated by any television administrator. For example, if we provide an advertisement produced by an advertiser to each sales branch, each sales branch must update the televisions that manage that advertisement, and some sales branches may place ads other than those listed above. Updating can also have an unfair advantage. Or any non-contractor may update their own ad.

That is, by inadvertently updating the advertising data on the television indiscriminately from the non-certified company, the user may encounter an unauthorized advertisement from the user's point of view, thereby causing a problem.

Accordingly, the present invention has been made to solve the above-described problem, the advertisement output device, such as a television that displays the advertisement on one side or the entire screen of the advertisement output can be updated to prevent only the reckless output of the advertisement advertising The present invention provides a method for updating advertisement data in an apparatus and an apparatus for updating the advertisement data.

1 is a configuration diagram schematically showing an entire system for performing a method for updating advertisement data in an advertisement output device according to an embodiment of the present invention.

Referring to FIG. 1, the entire system according to the present embodiment includes an advertisement production center 50, one or more branch servers 70-1, 70-2,. And an advertisement output device 10.

The advertisement production center 50 functions to request and produce an advertisement from an advertiser and provide advertisement data according to the produced advertisement to each branch server 70.

The advertisement data may be all types of content that may be displayed on a screen such as an image, a video such as a logo, as well as general text.

In particular, the advertisement production center 50 may encrypt the produced advertisement data using the authentication key. Therefore, the advertisement output device 10 subsequently decodes the advertisement data input for the update by using a decryption key (that is, if the decryption is successful, authentication may be processed as unsuccessful authentication), By outputting an advertisement image according to the corresponding advertisement data only when the decoding succeeds (that is, when the authentication succeeds), only the authenticated advertisement data can be used. Of course, the authentication key used in the advertisement production center 50 should be linked with the decryption key so that the advertisement data can be decrypted by the decryption key in the advertisement output device 10.

Herein, the advertisement data is encrypted by the authentication key and the authentication is performed on the advertisement data in a manner that is decrypted by the decryption key. However, the authentication for authentication to the advertisement data is performed instead of the encryption using the authentication key. The key may be included, and authentication may be performed by using the decryption key included in the advertisement output device 10 (for example, comparing the authentication key with the decryption key). That is, the advertisement output device 10 performs an authentication procedure using the authentication key included in the advertisement data (authentication using the decryption key provided), updates the corresponding advertisement data only when the authentication is successful, and then outputs the advertisement later. Updated advertising data is available.

In addition to the authentication method according to the comparison of the authentication key and the decryption key as described above, or the decryption method by the encryption / decryption key to the authentication key, all the methods of authentication processing using the authentication key and the decryption key may be applied in the same manner. Will be more self-explanatory. However, hereinafter, for convenience of description, the advertisement data is encrypted using the authentication key, and the decryption is performed using the decryption key.

The branch server 70 provided in each sales point receives the advertisement data from the advertisement production center 50, the person in charge of the sales point stores the corresponding advertisement data in the update device 30, and the advertisement output device 10 Go to the provided place to update the advertisement data previously stored in the advertisement output device 10 by using the update device 30.

Here, the update device 30 may be a USB memory as shown in the figure coupled to the advertisement output device 10 to transmit and receive data via USB communication. Of course, the present invention is not limited thereto, and all types of devices capable of storing specific data (that is, advertisement data) and transmitting data stored in a wired or wireless manner to the advertisement output device 10 are the same as the update device 30. Can be applied.

The advertisement output device 10 is a device for displaying advertisements according to advertisement data on one side or the whole of the screen, and may be, for example, a television as shown in the figure. The advertisement output device 10 may be provided with a set top box, etc., and may communicate with other devices (eg, the advertisement production center 50, etc.) through a communication network. Of course, the advertisement output device 10 is not limited to a television, and any device capable of outputting an advertisement image according to advertisement data stored in a display screen, such as a computer monitor, may be applied in the same manner. However, hereinafter, the television will be described as an example of the advertisement output device 10 for convenience of description.

When the advertisement output device 10 receives a request for updating the advertisement data from the update device 30, the advertisement output device 10 performs an authentication procedure for the advertisement data. As described above, a comparison between the authentication key and the decryption key, decryption using the decryption key of the advertisement data encrypted with the authentication key, and the like may be used.

According to an embodiment, the decryption key may be stored in advance in the advertisement output device 10. That is, the advertisement output device 10 may be shipped with the decryption key stored in the provided storage means. Of course, the information on the decryption key also has an advertising production center 50, the advertising production center 50 may use an authentication key corresponding to the decryption key. The authentication key used for encryption may be a public key method or a common key method. Of course, the corresponding decryption key stored in the advertisement output device 10 is preferably implemented as a public key method so that it cannot be read from the outside, but the authentication processing method according to the public key method as well as the common key is an external decryption key. There is still a possibility of being read, so there could be a vulnerability in security.

According to another embodiment, when the advertisement production center 50 produces and distributes new advertisement data to be updated on the advertisement output device 10, the corresponding decryption key may be directly provided to the advertisement output device 10 through the communication network every time. It may be. Accordingly, the advertisement output device 10 may receive the decryption key from the advertisement production center 50 through the communication network, and may authenticate the advertisement data received from the update device 30. Of course, in this case, the advertisement production center 50 may waste resources in that it must communicate with the advertisement output device 10 through a communication network.

Hereinafter, an authentication processing scheme according to another embodiment for providing more stable security will be described.

First, the authentication processing method for the embodiment of FIG. 2 will be described schematically. The advertisement output device 10 includes a plurality of decryption keys. The advertisement output device 10 selects one decryption key according to a specific criterion (for example, a predetermined order, etc.) and uses it for authentication of advertisement data. For example, assuming that the advertisement output device 10 is provided with three decryption keys A, B, and C, and it is now time to use C, the advertisement production center 50 generates an authentication key C 'corresponding to C. To encrypt advertising data. Of course, the advertisement production center 50 should also be aware of the order in which the decryption keys in the advertisement output device 10 are used. Accordingly, the advertisement output device 10 attempts to decode the updated advertisement data by using the decryption key C, which is in turn to be used.

In order to provide more stable security, the advertisement production center 50 may provide information about a decryption key to be used among the plurality of decryption keys in real time through a communication network such as the Internet network in response to a request from the advertisement output device 10. have. That is, when new advertisement data is produced and the advertisement is attempted to be distributed to each advertisement output device 10, the advertisement production center 50 decodes the decryption key identification information corresponding to the authentication key (for example, a serial number previously assigned to the decryption key, etc.). ) May be provided to the advertisement output device 10 through a communication network.

Hereinafter, an authentication process according to the present embodiment as described above will be described with reference to the drawings.

Referring to FIG. 2, when an advertisement data update request is input from a wired or wirelessly connected update device 30 (step 210), the advertisement output device 10 may select one of a plurality of decryption keys according to a specific criterion. Select (step 220). As described above, the advertisement output device 10 may obtain information about which decryption key to use for authentication of the authentication key from the advertisement production center 50 through a communication network in real time.

Here, the update may delete the old advertisement data and store the new advertisement data, or may be stored together without deleting the old advertisement data. The updated manner may be separately included in the advertisement data and may be described in the update information in a form interpretable by the advertisement output device 10. Subsequently, the advertisement output device 10 may display an advertisement image according to the updated advertisement data on a display screen.

If it is not decoded (i.e., authentication fails), the advertisement output device 10 does not perform the update (e.g., deletes the requested and copied advertisement data), outputs an error message, Update failure processing such as a warning sound output is performed (step 260).

According to an embodiment different from the above-described embodiment, the advertisement production center 50 periodically updates the authentication key and the decryption key, and directly or via the communication network updates information about the newly updated decryption key. The advertisement output device 10 passes through. In particular, the newly updated decryption key is encrypted with the previous authentication key. Accordingly, the advertisement output device 10 may use the decryption key used for decoding the advertisement data later by decoding the received new decryption key with the previous decryption key.

An embodiment thereof will be described with reference to FIG. 3. The advertisement output device 10 is requested to update advertisement data from the connected update device 30 (step 310).

The advertisement output device 10 extracts the decryption key information included in the advertisement data (step 320), and decodes the extracted decryption key information using the previous decryption key (step 330). Of course, when the decryption key information is not included in the advertisement data or the encryption is not decrypted, the corresponding advertisement data requested for updating may be recognized as not authenticated.

The encrypted data decrypted information is set and used as a new decryption key to decrypt the requested advertisement data (step 340). Subsequent steps may be performed, including step 240 according to FIG. 2.

According to this embodiment, more stable security can be maintained by periodically updating the authentication key and the decryption key.

According to another embodiment, the advertisement production center 50 generates the advertisement data in a file format unknown to the outside except for the advertisement output device 10, rather than a file format well known to the outside such as JPG and AVI. do. Therefore, even if the advertisement data is exposed to the outside, the security of the advertisement data can be achieved, and further, the advertisement output device 10 can recognize only the advertisement data of the corresponding format as authenticated, thereby preventing the update of the unauthorized advertisement data. have.

The authentication processing method using the file format of the advertisement data according to the present embodiment may be used in combination with the method as shown in FIG. 2 or FIG. 3. That is, the advertisement data can be generated in a plurality of file formats, and one file format is determined according to a specific criterion. Therefore, the advertisement output device 10 recognizes the corresponding file format and the requested advertisement data is updated. You can update only in the format. In addition, the format data generated in the format of the previously updated advertisement data is included in the advertisement data, and the advertisement output device 10 determines the update process by comparing the format of the newly requested advertisement data by recognizing the corresponding format information.
