     DETAILED DESCRIPTION 
       [0027]    Reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The same reference numbers are generally used throughout the drawings to refer to the same or like parts. Hereinafter, a method and system for prohibiting copy of contents according to the present invention will be explained with reference to the accompanying drawings. 
         [0028]      FIG. 1  is an exemplary screen showing a result of an Internet search, using a is search query “patent.” The result includes a preview  4  of a webpage located from the search. In one embodiment, the search result does not include the preview; however, the preview may display upon user&#39;s selection or clicking of the preview link  2 . 
         [0029]    Certain webpages contain proprietary information or contents, which the owners or posters of such information or contents do not wish to distribute without their authorization. Some of such webpages use a copy prevention or prohibition technology that prevents others from copying such information or contents without authorization of the owners or the webpage administrators. When these webpages are listed in Internet search results like  FIG. 1 , at least a portion of the proprietary information or contents may be displayed in the preview section  4  of the search result page. In some situations, even though these webpages adopt a copy prevention technology, it is possible that the preview portion may still be copied for use in another software application. Embodiments of the invention provide solutions and ways to prevent unauthorized copying of such proprietary information or contents from previews of webpages. 
         [0030]      FIG. 2  is a diagram showing a network with a copy prohibition system according to one embodiment of the present invention. As shown in  FIG. 2 , the copy prohibition system  10  provides a tool for blocking copying of a preview content provided to a user terminal  14  through Internet  12 . The copy prohibition system  10  includes an interface unit  16 , a search unit  18 , a database  20  and a copy prohibition unit  22 . 
         [0031]    The interface unit  16  receives a search query from a user; and provides a search result obtained in response to the search query to the user. Also, the interface unit  16  receives a preview request for a predetermined webpage among the search result provided from the user; and provides a preview page, into which copy prohibition means is inserted in response to the received preview request, to the user. 
         [0032]    The search unit  18  executes or conducts a search for the search query received through the interface unit  16 ; obtains the search result in response to the search query; and provides the obtained search result to the user through the interface unit  16 . One embodiment of the present invention describes that the copy prohibition system  10  includes the search unit  18 . In a modified embodiment of the present invention, the copy prohibition system  10  may not include the search unit  18 , that is, the copy prohibition system  10  receives the search result obtained in response to the search query from an external search server (not shown). 
         [0033]    The preview page for the webpage is stored in the database  20 . The preview page can be stored in the database  20  by caching the webpage. In this case, caching means that the corresponding webpage is stored in the additional database so as to provide the corresponding webpage to the user rapidly. If needed, the webpage may be firstly edited and then stored as well. 
         [0034]    One embodiment of the present invention describes that the database  20  is included in the copy prohibition system  10 . In the modified embodiment of the present invention, the copy prohibition system  10  may use the database (not shown) included in the external search server (not shown), instead of including the database  20  therein. 
         [0035]    The copy prohibition unit  22  generates the copy prohibition means; and inserts the generated copy prohibition means into the preview page read from the database  20 . In the embodiment of the present invention, generation and insertion of the copy prohibition means may be implemented using Java Script. Java Script corresponds to a script programming language proposed so as to dynamically execute the webpage, that is, object-based script programming language based on a prototype concept. 
         [0036]    The copy prohibition unit  22  generates the copy prohibition means using Java Script; and inserts the generated copy prohibition means into HTML document of the corresponding preview page using tag “script”. 
         [0037]    When the copy prohibition unit  22  generates the copy prohibition means in one embodiment of the present invention, it is possible for the copy prohibition means to include information displaying that the copy is prohibited in the corresponding preview page. Thus, the user becomes easily aware of that the copy is prohibited in the corresponding preview page. 
         [0038]    In the above embodiment of the present invention, the copy prohibition unit  22  directly generates the copy prohibition means; and inserts the generated copy prohibition means into the preview page. In the modified embodiment of the present invention, the copy prohibition unit  22  may insert the copy prohibition means generated by the external server into the preview page. In this case, the copy prohibition unit  22  receives the copy prohibition means from the external server; and inserts the received copy prohibition means into the preview page. 
         [0039]    In the above embodiment of the present invention, the copy prohibition system  10  inserts the copy prohibition means into the preview page. In another embodiment of the present invention, the copy prohibition means may be selectively inserted into the preview page. 
         [0040]    For this, the copy prohibition system  10  includes a determining unit  24  to determine whether the copy prohibition function is included in the webpage on user&#39;s preview request. Thus, only when it is determined that the copy prohibition function is included in the corresponding webpage, the copy prohibition means is inserted into the preview page. 
         [0041]    In case of the webpage built so as to prohibit the copy of predetermined information, the webpage can prohibit the copy of information in itself. General preview services do not allow the execution of script. In this respect, the copy prohibition of preview page is determined based on whether the webpage includes the copy prohibition function in itself. 
         [0042]    In one embodiment of the present invention, the determining unit  24  determines whether the webpage includes the information for the copy prohibition of webpage in a webpage parsing step for generating the preview page, to thereby determine whether the webpage includes the copy prohibition function. For example, it is determined that the corresponding webpage includes the copy prohibition function when the corresponding webpage includes a code for realizing the copy prohibition function, or a tag for a copy or paste pre-defined in Java Script object of the webpage. 
         [0043]    In another embodiment of the present invention, when a Uniform Resource Location (URL) of the webpage falls into any URL in a list of predetermined URLs, the copy prohibition function can be inserted into the preview page of the corresponding webpage. In this case, the determining unit  28  determines whether the URL of the corresponding webpage is included in the list of predetermined URLs. 
         [0044]    In another embodiment of the present invention, the webpage may include the copy prohibition function in itself. Then, it could be determined whether the copy prohibition function of the webpage is also implemented in the preview page in the webpage caching step. If not, the copy prohibition means may be inserted into the preview page. 
         [0045]    The above-mentioned embodiment of the present invention describes that the copy prohibition system  10  is applied to the webpage included in the search result. In a modified embodiment of the present invention, the copy prohibition system  10  may be applied to a general webpage other than the webpage included in the search result. For example, a website may provide link information for certain contents, and also provide a preview service for the corresponding contents. 
         [0046]    A method for prohibiting the copy of preview page using the aforementioned copy prohibition system according to the present invention will be described with reference to  FIGS. 3 and 4 . Referring to  FIG. 3 , first, the search query is received from the user, and the search result obtained in response to the corresponding search query is provided to the user (S 100 ). When the selection request for the preview page of the predetermined webpage included in the search result is received from the user (S 110 ), the corresponding preview page is read from the database  20  (S 120 ), and the copy prohibition means to be inserted into the preview page is generated (S 125 ). Then, after inserting the generated copy prohibition means into the preview page read (S 130 ), the preview page with the copy prohibition means inserted thereinto is provided to the user (S 140 ). In one embodiment of the present invention, the generation and insertion of the copy prohibition means can be implemented using Java Script. 
         [0047]    The aforementioned embodiment of the present invention describes that the copy prohibition means is inserted into the preview page. In the modified embodiment of the present invention, the copy prohibition means may be inserted selectively. 
         [0048]    As shown in  FIG. 4 , the search query is received from the user, and the search result obtained in response to the corresponding search query is provided to the user (S 200 ). When the selection request for the preview page of the predetermined webpage included in the search result is received from the user (S 210 ), the corresponding preview page is read from the database  20  (S 215 ). 
         [0049]    Then, it is determined whether the webpage of the corresponding preview page includes the copy prohibition function in itself (S 220 ). When it is determined that the corresponding webpage includes the copy prohibition function in itself, the copy prohibition means is generated (S 225 ); the generated copy prohibition means is inserted into the preview page read (S 230 ); and the preview page with the copy prohibition means inserted thereinto is provided to the user (S 240 ). 
         [0050]    In case of the webpage built so as to prohibit the copy of predetermined information, the insertion of the copy prohibition means into the preview page is determined based on whether the webpage includes the copy prohibition function in itself, so that it disenables the copy of the predetermined information included in the webpage. General preview services do not allow the execution of script. In this respect, the copy prohibition of preview page is determined based on whether the webpage includes the copy prohibition function in itself. 
         [0051]    If the webpage includes the copy prohibition function in itself, it may be necessary for the preview page to include the copy prohibition function therein. If not, it may not be necessary for the preview page to include the copy prohibition function therein. 
         [0052]    When the copy prohibition function is not included in the preview page, the copy prohibition means can be inserted into the preview page after determining whether the corresponding webpage includes the copy prohibition function in itself and the copy prohibition function of the corresponding webpage is also implemented in the preview page in the webpage caching step. When it is determined that the webpage of the corresponding preview page includes the copy prohibition function in itself during the step of S 220 , the preview page read from the database  20  is provided to the user (S 250 ). 
         [0053]    In another embodiment of the present invention, it is determined whether the URL of the corresponding webpage is included in the list of predetermined URLs. When the URL of the corresponding webpage fall into any URL in the list of predetermined URLs, the copy prohibition function may be inserted into the preview page of the corresponding webpage. 
         [0054]    The aforementioned copy prohibition methods may be implemented in type of programs executed by various computers. In this case, the programs to execute the copy prohibition methods are stored in recording media readable by the computers, for example, hard-disc, CD-ROM, DVD, ROM, RAM or flash memory. 
         [0055]    As mentioned above, when receiving the preview request, the preview page with the copy prohibition means inserted thereinto is provided to the user, thereby protecting the copyright of webpage by prohibiting the illegitimate copy of the information displayed on the preview page. 
         [0056]    When providing the preview page to the user, the user can be notified that the corresponding preview page has the copy prohibition function. Thus, the user becomes easily aware of that the copy is prohibited in the corresponding preview page. 
         [0057]    The insertion of the copy prohibition means into the preview page is determined based on whether the webpage with the preview page requested by the user includes the copy prohibition function in itself, so that it is possible to reflect the intent of building the webpage with the copy prohibition function. 
         [0058]    For example, the aforementioned embodiment of the present invention describes that the copy prohibition means is inserted into the preview page. The preview page is only one example of caching the predetermined webpage. The insertion of copy prohibition means according to the present invention can be applied to all cases of caching the predetermined webpage, for example, more-view page or stored page, without limitation. 
         [0059]    The aforementioned embodiment of the present invention describes that the copy prohibition means inserted into the preview page is implemented in type of Java Script. In the modified embodiment of the present invention, the copy prohibition means may be implemented in type of Active X control, and furthermore, in any types of program execution code to prohibit the copy of preview page. 
         [0060]    Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
