The concept behind the tool is pretty simple: While you can put privacy settings into place to keep strangers from stumbling across your photos on your Facebook page, there’s no way to keep your Facebook friends from, well, sharing your photos wherever they want to.
For example, if you post an incriminating (take that how you will) photo on Facebook and one of your friends teasingly shares it on their wall, then other people could see it. Likewise, if your friend downloads that photo and their computer or email account is hacked, your photo could fall into the wrong hands.
McAfee Social Protection seeks to solve this problem by giving Facebook users a secure platform through which they can upload and share photos without having to worry about people downloading them, copying them, or otherwise sharing them with others.

Basically, this app helps ensure that your photos don’t fall into the wrong hands, even inadvertently. Since your friends cannot save or download your photos, even if their accounts or devices are compromised, your photos are safe.
That said, it’s not foolproof–obviously, if someone was really out to get that photo, there are workarounds (for example, you could just take a physical picture with a separate camera of the screen). But the app does present a stumbling block to the easy, one-click sharing that can sometimes make compromising photos go viral.

Of course, in order for Social Protection to work, people actually have to use it. It’s not quite as simple as uploading photos directly to Facebook–and McAfee hasn’t mentioned whether there will be a mobile component to the app–but the extra step might just be worth the extra protection.
