Protect yourself with HashGuard!
Video creators, do you have this problem?
"The video I spent a lot of time editing has been copied and uploaded without my permission..."
"Even though the video is monetized, the revenue has decreased due to the copied video..."
"Even if you protest on SNS, the other party will claim that the video is their own, so it will be difficult to resolve the issue..."

Unauthorized copying and illegal uploading are serious problems for creators who make money!
If the videos you worked so hard to create are copied and published, your income and creative motivation will be taken away.
Moreover, even if you protest on SNS, the owner of the fake account will also claim that the video is his own.
It will take time and effort to resolve the issue.
As a result, the freshness of the video decreases, and the revenue that could have been earned is lost.

HashGuard was developed to solve such problems.
