Abstract

PURPOSE: A method for providing images of an online publication is provided so that a client can be easily informed of wanted contents and a transmission speed can be remarkably increased by analyzing reaction of the client and automatically selecting and transmitting the images of appropriate resolution to the client. CONSTITUTION: A client accesses a web server of an institution through the Internet(S10). The client logs in the web server. Here, a client ID, access date and time, IP address or check sum data are stored in a client information database(S12). The information is encoded, and illegal duplication tracking information is generated and stored in the client information database(S14). The web server confirms whether the client transmits a transmission request of a random page, for example p-th page of an online publication(S16). According to the transmission request, the web server reads low resolution integrated images of the p-th page from an image server, and outputs the images to a monitor of the client(S18). The web server confirms whether the client transmits the transmission request of the px-th page for 3 to 5 seconds(S20). When there is no transmission request from the client, the web server judges that the client is interested in the currently-displayed p-th page, reads middle resolution integrated images of the p-th page from the image server, and transmits the images to the client(S22).

Description

Image transmission method for online publication

The present invention relates to a method for providing an image of an online publication. In particular, in providing an image of an online publication to a client, the present invention reflects offline reading behavior so that an online publication can be provided quickly without any inconvenience in viewing the image. A method of providing a publication.

In recent years, the use of the Internet has been established not only in the workplace but also in the home, and the Internet has become an indispensable means for communication or information transmission. In addition to this trend, in the publishing world, the so-called online publication, which is called an online publication, has been converted into a digital file, and a system that provides online to a desired reader is being used in part, and will be used more actively in the future. It is predicted to be.

However, when humans are reading publications that contain relatively many pictures, for example, magazines such as weekly / monthly magazines, or publications for products / advertisements such as catalogs, pages that are not of interest are immediately turned over by visual recognition. If you have what you need, stay on the page and read the contents only when you need to read the catalog and the contents.

On the other hand, these online publications, especially online publications that contain a lot of pictures in the content and are transmitted in the form of image data to the client (hereinafter, the term is used as a meaning of the customer or the PC used by the customer unless otherwise specified). In this case, since the amount of data per page is usually large, ranging from several hundreds [Kb] to several [Mb], it takes a considerable amount of time even if a high-speed Internet dedicated line is used.

Nevertheless, in providing an online publication in the past, the communication line and time due to the page that the client is not interested in because the high resolution integrated image is transmitted for all pages without considering the above-described reading behavior of the offline publication. Wasteful factor is generated. In addition, the client has a problem that the client is slow and uncomfortable with the online publication, and thus there is a problem that the online publication is not activated.

On the other hand, in the case of online publications, the contents are provided in the form of intangibles without direct contact with each other, and it is possible to transmit them in bundles simultaneously through a communication network, thereby preventing illegal copying from the provider's point of view. Countermeasures are becoming an important issue. As part of the countermeasure, the identification information (hereinafter referred to as "piracy tracking information") of the client that received the data is encrypted and inserted into the image data transmitted as part of the countermeasure. To make it possible.

However, in inserting illegal copy tracking information into the image data of the conventional online publication, since the whole image is being worked on, the amount of work is enormous and accordingly, there is a problem that a heavy load is placed on the server.

The present invention provides a method for providing an image of an online publication that can automatically increase the transmission speed without interrupting the client's knowledge of desired contents by automatically selecting and providing an image having an appropriate resolution according to the client's response. The purpose is.

It is another object of the present invention to insert an illegal copy tracking information for tracking an illegal copy of an online publication in image data, and to insert the segmented portion of the image, thereby reducing the amount of work for the online publication image providing method. To provide.

In order to achieve the above object, the present invention provides an online publication providing institution and an online publication providing method performed by an online publication providing institution in which a client equipped with a stretching function and a multitasking function is connected by a communication network, the method comprising: (a Preparing a relative low resolution integrated image and a relative medium resolution integrated image to be enlarged by a stretching function after being transmitted to the client for the same original; (b) transmitting the low resolution integrated image when a transmission request for any page of the original exists; (c) determining whether there is a transmission request for another page of the original until a predetermined time elapses after the low resolution integrated image is transmitted; (d) transmitting the low resolution integrated image for the other page if there is a transmission request for the other page before the predetermined time elapses as a result of the determination in step (c); and (e) And as a result of the determination in step (c), if the transmission request for the other page does not exist until a predetermined time elapses, transmitting the medium resolution integrated image for the arbitrary page. do.

In the above-described configuration, if the low resolution integrated image or the medium resolution integrated image is additionally transmitted to a page having a predetermined relationship with the transmitted page after the transmission of the low resolution integrated image or the medium resolution integrated image is completed, When there is a transfer request from the client for the page having the predetermined relationship, the page can be quickly displayed on the monitor screen.

Furthermore, in the step (a), further preparing a high resolution split image provided in the request for the detailed image transmission from the client for the original, (f) determining whether a request for the transmission of the detailed image from the client exists; and g) transmitting the high resolution split image when there is a request for transmission of a detailed image from a client.

In addition, the method further includes (h) encrypting the login information of the client and (i) inserting the encrypted contents into the partial partitioned image of the high resolution partitioned image, thereby inserting piracy tracking information with a small amount of work. .

In addition, (f1) if there is a request for transmission of the detailed image from the client in step (f), confirming the desired part of the transmission request, and (g1) transmitting the high resolution split image in the step (g). In this case, the step (f1) includes the step of performing the transmission in the order of the high resolution split image in a position relatively close to the position identified, it is possible to provide a faster image to the client.

Hereinafter, an image providing method of an online publication of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram illustrating a network in which an image providing method of an online publication of the present invention may be implemented, and FIG. 2 is a diagram for describing an image stored in an image server in FIG. 1. First, as illustrated in FIG. 1, the method for providing an image of an online publication of the present invention is largely made by providing an online publication providing institution 100 and a client 200 by an appropriate communication network, for example, the Internet. The online publication provider 100 (hereinafter referred to simply as the "provider agency") includes an image generator 110 for generating an image to be provided again, and an image server 120 for storing the image generated by the image generator 110. , A customer information database 130 storing various information about the client 200, and a web server 140 directly communicating with the client 200.

In the above-described configuration, the image generator 110 outputs an image having various formats used by the editing software used in the current publication in the case of electronic material to an EPS (Encapsulated PostScript), which is a general vector file format, and then converts the image into JPEG. (Joint Photographic Experts Group) format to create and, in the case of off-line publications, scan with a scanner to produce images in JPEG format directly.

As such, in the present invention, by using a standard format in the JPEG format, an online publication implemented as an image using only a general web browser such as Microsoft's Internet Explorer (registered trademark) without a client installing separate dedicated software can be used. You will get it.

On the other hand, the image generator 110 is reduced to the original image, such as (a) of Figure 2 obtained in this way, for example, reduced to about 1/16, as shown in (b) of FIG. (Hereinafter referred to as "low resolution integrated image"). The image generator 110 also reduces the original image to, for example, one quarter, so that an integrated image having a relatively medium resolution as described in (c) of FIG. 2 (hereinafter referred to as "medium resolution integrated image"). ), And finally, as shown in (d) of FIG. 2, an image obtained by dividing the original image itself into n pieces (hereinafter, referred to as "division"), for example, several to several tens (hereinafter, " High resolution split image ".

Then, the processed image is stored in the corresponding folders 122, 124, 126, separated by files by the download module of the image server 120, and then selected by the web server 140 On request, the appropriate one will be provided. Here, a low resolution integrated image may typically have a data amount of several hundreds [byte] to several [Kb] or less, and a medium resolution image may typically have a data amount of several [Kb] to several tens [Kb] or less. have.

The web server 130 is implemented as a common gateway interface (CGI) in general web server software using the existing HTTP (Hypertext Transfer Protocol). For example, the ISAPI (Internet of Internet Information Server) server of Microsoft Corporation Server Application Program Interface) can be implemented as CGI.

3 is a flowchart illustrating an image providing method of an online publication according to a preferred embodiment of the present invention, and FIGS. 4A to 4C illustrate low resolution integrated images, medium resolution integrated images, and high resolution integrated images displayed on a client monitor. It is shown as an enemy. First, as shown in FIG. 3, when the client 200 accesses the web server 140 of the provider 100 through the Internet in step S10, a log in is performed in step S12. In the process, information such as ID of the client 200, an access date and time, an IP address of the client 200 or check sum data is checked and stored in the customer information DB 130. Of course, information such as an address, a phone number, or a social security number of a user who is a client may be obtained in advance during the membership registration process and stored in the customer DB 130.

Next, in step S14, the information obtained in the above-described login process is encrypted to generate illegal copy tracking information, and then stored in the customer information DB 130. In this case, as the encryption method, n number, preferably, a numeric method (hereinafter, referred to as "numeric tracking information") of decimal number or more, may be used, and the number of divisions of the high resolution split image described above with n representing the decimal number may be used. It is preferable to match (n).

In this state where the login is performed so that the client 200 can use the information provided by the provider 100, in step S16, the web server 130 can select any page in the online publication provided by itself, for example p page. It is determined whether there is a transmission request from the client 200 for the image. As a result of the determination in step S16, when there is a transmission request from the client 200, in step S18, the web server 130 first receives the low resolution integrated image for the corresponding p page from the image server 120 and transmits the client. Output on the monitor of (200).

As soon as this operation is completed, a request is made to the web browser of the client 200 to request a p + 2 or p-2, which is a low-resolution integrated image and a difference adjacent page, for the p + 1 or p-1 page adjacent to the currently output p page. The low resolution integrated image for the page is sequentially received and stored in its own memory. In this case, it is preferable to receive in the order of p + 1-> p-1-> p + 2-> p-2. In addition, such a background task is achieved by a multi-tasking function built in the client 200. As described above, since the low-resolution integrated image is at most [Kb] or less, it may be short for one second. Even a few pages can be sent in time.

Meanwhile, a general web browser mounted on the client 200 is provided with a stretching function as a basic specification. The low resolution integrated image transmitted in step S18 is expanded to the entire client 200 monitor screen by the stretching function. As a result, as shown in FIG. 4A, the client is provided with an image such that the client can determine whether the overall outline is recognized.

In this state, if it is determined that the client, the client, is not the desired content, the web server 130 quickly displays an image of another px page, typically an adjacent page p + 1 or p-1 page, if it is not desired. You will be asked for In view of this, in step S20, the web server 130 is another px page from the client 200 until a predetermined time (t), for example, from 2 seconds to 10 seconds, preferably 3 to 5 seconds. Determine if there is a request to send an image.

As a result of the determination in step S20, when there is no request to transmit another page image from the client 200 until a predetermined time t elapses, the web server 130 may display the p page on which the client 200 is currently displayed. If it is determined that there is interest, the step S22 is performed to retrieve the medium resolution integrated image for the p page from the image server 120 and transmit it to the client 200. Thereafter, the client 200 overlays the medium resolution integrated image thus transmitted by its own function on the currently displayed low resolution integrated image. In this process, the stretching function is used. As a result, as shown in FIG. 4B, the image is output to a degree that can grasp not only the overall outline but also the details. In addition, when there is time, the medium resolution image for the adjacent p + 1 or p-1 page is transmitted to the client 200 and stored.

Unlike the above, when a request for transmission of another pxpage image is received from the client 200 before a predetermined time t elapses in step S20, the web server 130 performs step S36 to perform a low resolution on the requested pxpage. The integrated image is retrieved from the image server 120 and transmitted to be output on the monitor of the client 200. Of course, even in this case, the pages adjacent to the currently displayed px page are transmitted so that the client 200 stores them in its own memory.

On the other hand, if the page requested by the client 200 in step S36 is p + 1, p-1, p + 2 or p-2 pages adjacent to the p page, that is, the page has already transmitted the low resolution integrated image in step S18 The client 200 may quickly display a desired image regardless of the transmission speed from the web server 130 by loading it from its own memory and displaying it on a monitor.

As described above, the method of the present invention allows the client 200 to receive an image of a page which is expected to be requested next in advance while the network is free, and when the page is requested, the client performs its own operation to execute the page. It can be displayed quickly. Here, which pages are to be transmitted in advance or in what order the pages are to be transmitted in advance may be appropriately changed depending on the amount of data the pages have, the transmission speed of the network, and the like.

Meanwhile, when the low resolution integrated image or the medium resolution integrated image is displayed on the monitor of the client 200 or when the client 200 requests to transmit the high resolution image for the page while the display is completed, the web server 130 may perform the step. After determining this in S24, step S34 is performed to retrieve and transmit the high resolution split image of the corresponding page from the image server 1120.

In this case, in order to provide convenience to the client 200, the web server 130 performs step S28 in addition to the portion of the client 200 that the client 200 particularly wants to see on the currently displayed page (the determination of the position of this portion For example, it may be known by the click position of the client 200 mouse. Further, in performing step S34, it is preferable to sequentially transmit the high resolution split image corresponding to the identified portion first, and then transmit the high resolution split image of the portion adjacent to the portion. That is, when the position clicked on by the client 200 corresponds to, for example, the split image of row c, the split image of row c is transmitted first, and then the split image of row c-1 and row c + 1 is transmitted. Subsequently, the transfer is performed by transmitting split images of rows c-2 and c + 2.

On the other hand, if encryption for the online publication is requested, steps S30 and S32 are additionally performed before step S34 to insert the above-described illegal copy tracking information into at least part of the high resolution split image. In this case, as an insertion method of the piracy tracking information, for example, a specific graphic element having a size that is visually recognizable even when the online publication is printed corresponds to the number of digits of the above-described numeric tracking information. It is inserted into the page and sent.

FIG. 5 illustrates an image displayed on the client monitor in an encrypted state in FIG. 3. As shown in FIG. 5, the insertion position of the graphic element on each page may be a high resolution split image having an action value corresponding to the number of digits of the numerical tracking information. For example, if the numeric tracking information generated for any client 200 is 4162 _{16 in} hexadecimal, the number of high resolution split images is also preferably 16. In this case, the page into which the graphic element is inserted is 4 pages total. The first page is inserted into the fourth high resolution split image corresponding to "4" which is the number of the first digit of the numeric tracking information. Similarly, on page 2, a graphic element is inserted in the first high resolution split image in the high resolution split image, corresponding to the second digit "1". The same is true for pages 3 and 4, which allows at least the entire online publication to be pirated so that the identity of the pirate can be verified by restoring the numeric tracking information by the page containing the graphic element and then decrypting it. do.

In the present invention, since the illegal copy tracking information is inserted into the image, the amount of work is drastically reduced because the work is performed on only a partial image of the entire image.

On the other hand, while performing the above-described steps appropriately, in step S26 it is determined whether the client 200 wants to log out, the program is terminated when the client 200 wants to log out.

This invention is not limited to the above-mentioned embodiment, It can be variously modified and implemented within the range which the technical idea of this invention allows. For example, in the above-described embodiment, the high resolution image is transmitted as the divided image, but the high resolution image may also be configured as the integrated image and transmitted. In this case, of course, the piracy tracking information will be performed on the integrated image.

According to the method of providing an online publication of the present invention as described above, by analyzing the client's response and automatically selecting and providing an image having an appropriate resolution, the transmission speed is dramatically increased while preventing the client from learning the desired contents. You can.

In addition, in inserting the piracy tracking information for tracking the illegal copy of the online publication in the image data, it is possible to improve the operation efficiency of the equipment by inserting the divided parts of the image, thereby drastically reducing the workload for this. It works.
