With the popularization of the Internet and e-commerce and the expansion of e-government services, a variety of recorded data and documents that are relevant to such transactions and services are constantly created and exchanged electronically.This typically takes the form of multimedia content sold over the Internet, which in fact began with the distribution of digitized music, and currently a wide variety of content-based businesses are being launched.In such situations, it is important to preserve the reliability of electronic data and documents by ensuring that the content cannot be altered.In addition to its superior quality, digital content has the characteristics that it is also easy to handle and its quality does not deteriorate even if the content is duplicated.On the other hand, due to the fact that the quality does not deteriorate, digital content also bears the risk that it can be easily duplicated illegally.The problem of content usage abuse that has accompanied the popularization of the Internet and advances in digital technology is one of the barriers obstructing the operation of digital content-based businesses, and the damage that this abuse causes is growing.One technology that can resolve these problems is digital watermarking.Digital watermarking technology leaves evidence that can be used to enforce the copyright of the digital content, and it embeds the creator's information into the digital content itself.In this research, an Internet search engine was operated with the objective of detecting abuse of digital content early, as well as identifying websites disclosing digital content without authorization.By using digital watermarking technology, we provided a means for resolving the problem of damage incurred to e-commerce websites due to copyright infringement.We also embedded information into the content, deterred the abuse of content usage through detection, and verified the results.
