Protect the Privacy of Your Video Entry; Use YouTube's "Unlisted" Option
The following information is provided from the YouTube site:
"An unlisted video is a different type of private video. Unlisted means that only people who know the link to the video can view it (such as friends or family to whom you send the link). An unlisted video will not appear in any of YouTube's public spaces (such as search results, your channel, or the Browse page). An unlisted video is different to a private video in these ways:
Even though your video will not appear in any of YouTube's public spaces, links to the video could still appear elsewhere on the web if anyone who knows the video's URL shares it. It is therefore up to you to maintain the privacy of your video and the unlisted URL. You can further restrict the video at any time by returning to your account and marking the video as Private.
How do I create an unlisted video?
You can choose to make any of your uploads an unlisted video in your YouTube Account settings. Here’s how:
Choose the video you want to edit and click the Edit button below the video thumbnail.
Scroll down to the Basic Info tab and find the Privacy section.
You'll see the option to make the video Public, Unlisted, or Private.
Select Unlisted. Make sure to click the Save Changes button at the bottom of the page.
How do I share an unlisted video? Once you’ve set your video as unlisted in your Account settings, you’re ready to share your video. In order to share your video, just send the video’s URL to the people with whom you’d like to have access to the video. They’ll then be able to view the video."
