Abstract(in English)	The Internet is now common tool used by corporations and individuals to send private or confidential information all over the world. However, this information is not always concealed from third parties. As a result, the field of digital-watermarking as a way of protecting the confidentiality of information is growing. This study shows the effects of a technique called "Keyfile" which determines the parameters of embedded information using 3^ digital contents. The use of "Keyfile" enables a firm to conceal its identity and advance information to clients without being decoded by parties.
