“The present invention relates to a server and a providing method.
“Description of the Related Art
“In recent years, an increasing number of companies are replacing paper medium information with document data for the purpose of improving work efficiency and resource saving by making paperless. For example, business forms managed in-house are also a target to be replaced. In particular, a large number of pages are often output as forms to be output in a core system of a company, a public office or the like, and thus management costs are enormous, so that the forms are made digitized.
“Also, use of cloud services is beginning to spread as a method of managing business data or performing various processes. More specifically, a user accesses a Web page of a cloud service from a Web browser of a client terminal via the Internet, and browses digitized form document data on the Web page. In this connection, it is expected that the number of use cases for editing and printing the form document data being browsed according to a business flow will increase.
“In case of handling the form document data on the Web page, an SVG (scalable vector graphics) format that has a high affinity with the Web may be used. By using the SVG format, image quality deterioration due to screen enlargement/reduction does not occur. Thus, it is possible to perform drawing using dynamic expressions that are difficult to achieve with conventional form document data, so that it is possible to realize a Web form with high added value.
“Besides, depending on a type of form document, there is a case where a form document with a high security level is displayed. More specifically, a form document created by insurance business often contains customer’s personal information, and care must be taken when handling the relevant form document. Japanese Patent Application Laid-Open No. 2002-215574 discloses a technique of browsing a document with an expiration date.”
