技术领域technical field
本发明涉及一种电子文件预览系统与方法，尤其关于一种不但能够便利使用者预览电子文件，而且还能够保护作者与出版商权益的电子文件预览系统与方法。The present invention relates to an electronic file preview system and method, in particular to an electronic file preview system and method that can not only facilitate users to preview electronic files, but also protect the rights and interests of authors and publishers.
背景技术Background technique
在传统书店中，读者可以翻阅书籍，以确保书籍是否值得购买。在这个过程中，读者可以自由翻阅文件的任何一页，除了书店关门和不能像在家中阅读一样舒适之外，没有更多的限制。In a traditional bookstore, readers flip through books to make sure they are worth buying. In this process, readers are free to flip through any page of the document, and there are no more restrictions except that the bookstore is closed and cannot be as comfortable as reading at home.
随着网际网络的日益普及，各种电子文件阅读软件与设备的不断出现，以及网络购物系统安全性与版权保护方法的提高，电子文件作为一种全新的书籍出版、发行、销售及阅读方式，与传统的书籍(纸张文件)相比，其成本低、具简便性、无时间与空间限制等优势日渐显现。预览是书籍销售过程中一个不可或缺的环节，它是为读者提供了解与选择书籍的方法。With the increasing popularity of the Internet, the continuous emergence of various electronic file reading software and equipment, and the improvement of the security and copyright protection methods of online shopping systems, electronic files are a new way of publishing, distributing, selling and reading books. Compared with traditional books (paper documents), its advantages such as low cost, simplicity, and no time and space constraints are increasingly apparent. Preview is an integral part of the book sales process, it is to provide readers with a way to understand and choose books.
在网络环境下，由于档案或文字的复制非常容易，所以对版权的保护造成了困难。例如，当电子文件经由网络的网页浏览以呈现给使用者时，使用者可以利用浏览器的复制与打印功能来取得并保留电子文件的内容，因此完全无法保护版权。另外，当使用者下载具有时间限制的完整电子文件时，因为上述的时间限制功能可能被破解，所以同样无法保护版权。In the network environment, due to the very easy copying of files or texts, it is difficult to protect copyright. For example, when an electronic document is presented to a user through web browsing on the network, the user can use the copy and print functions of the browser to obtain and retain the content of the electronic document, so the copyright cannot be protected at all. In addition, when a user downloads a complete electronic file with a time limit, the above-mentioned time limit function may be cracked, so the copyright cannot be protected either.
另外，如果为了保护版权而只开放部分电子文件内容供使用者预览，可能会造成使用者的不便。例如，当只提供电子文件的简介时，使用者无法从中了解其具体内容与风格。另外，当只提供电子文件的章节精选时，使用者只能了解电子文件的少数重点，所以使用者可能会因断章取义而误解电子文件的全貌。In addition, if only part of the content of the electronic document is opened for users to preview in order to protect copyright, it may cause inconvenience to users. For example, when only the brief introduction of the electronic document is provided, the user cannot understand its specific content and style. In addition, when only selected chapters of the electronic document are provided, the user can only understand a few key points of the electronic document, so the user may misunderstand the whole picture of the electronic document by taking it out of context.
由以上所述，可以得知在习知技术中，不是限制了读者预览的自由度，就是存在版权保护的问题，所以损害了作者与出版商的权益。因此如何提供给使用者充分预览的自由度与保障作者与出版商权益的电子文件，已成为一亟待解决的重要课题。From the above, it can be seen that in the conventional technology, either the freedom of previewing by readers is restricted, or there is a problem of copyright protection, which damages the rights and interests of authors and publishers.
