In an announcement on their blog, YouTube reveled it has added a new tool that allowed users to blur out the faces in an uploaded video. In an attempt to give anonymity to users the site took this step.
The site announced in it’s post, "Whether you want to share sensitive protest footage without exposing the faces of the activists involved, or share the winning point in your 8-year-old’s basketball game without broadcasting the children’s faces to the world, our face blurring technology is a first step towards providing visual anonymity for video on YouTube."
After uploading the video, YouTube’s Video Enhancement tool will lead you to additional features, where the video uploader can click apply under “blur all faces”. Selecting “delete original video” will then delete the copy of the video with exposed faces. However, YouTube states that the technology is imperfect and may leave some faces un-blurred. But the video can be viewed before you upload it.
Spokesperson for YouTube, Jessica Mason stated that the company is working on perfecting the technology, "We use an algorithm that scans a video and detects facial features like eyes. From there it blurs the detected faces by adding things like noise and pixelation to the detected features," she wrote in an email to Ars.
