Description
The present invention provides a software compilation and software quality verification, distribution, and sales management method for a software sales and distribution system for use in a computer and a portable information communication device using a wired or wireless transmission method in an information communication network, and a computer and a portable information communication device. The present invention relates to the technical idea of identifying copyrights by finding and inspecting copyrights of pictures, music, sounds, icons, and symbologies embedded in a program for use.
Digital Rights Management (DRM) system is one of the computerizations in which all elements such as server security, system security, information security, hacking, and information management are concentrated enough to be called 'flowers' in security, like online games. Field.
Historical information (hereinafter referred to as content) is not a big problem because of the media cost or quality deterioration even if the copy is made by distributing the paper, CD, plastic, etc. based on offline.
However, now that all content is digitized, the nature of the digital does not degrade the quality of the original and the copy, and the cost of copying converges to zero, so many people want to copy and use it without paying for the content if possible.
The creator of the content (hereinafter referred to as the copyright holder) should, of course, have to pay the price from the users. If there is no information protection device, the user will use the content without paying the price. Thus, the copyright holder has no place to pay for his efforts. The DRM system is an information protection device to protect the rights of rights holders.
It has been less than 20 years since the DRM system was born. In the early days of the DRM system, most viewer-based DRM systems were applied in the form of specially designed programs (viewers) that drive security-enabled contents to prevent illegal use by users.
Since then, the viewer plug-in DRM system appeared by inserting a security plug-in into a popular viewer.
In recent years, the security of the operating system has evolved to a viewer-independent DRM system that supports a general-purpose viewer. As such, the DRM system has been developed in a different way from academia and industry.
