Facebook Profile Picture Guard: Completely Preventive or just a Deterrent?

Facebook Profile Guard

This week, Facebook India launched a new tool called the Profile Picture Guard, which is aimed at preventing misuse of profile pictures by third parties and thereby giving an enhanced sense of privacy and safety to the users. But how well can it actually protect user privacy? Continue reading “Facebook Profile Picture Guard: Completely Preventive or just a Deterrent?”

Facebook employing Image Recognition in Accessibility: An Informal Evaluation

Machine learning algorithms (speculative) in use to predict age of people featuring in photo. Prediction not quite accurate in this case; though some might disagree!

Image recognition, especially, facial recognition is nothing new to casual users of smartphones and social networks. Many social networks including Facebook has been using facial recognition to suggest the names of “friends” while tagging newly uploaded photos. With increasing confidence values provided by modified algorithms, apps like Facebook Moments now boldly suggests that you send photos to recognised friends who feature in them. Extensive research work is being carried out in the domain of image recognition by academics and companies to further this kind of applications. In a paper titled DeepFace: Closing the Gap to Human-Level Performance in Face Verification, Taigman et. al. have proposed an approach for face recognition in unconstrained images which performs remarkably with an “accuracy of 97.35% on the Labeled Faces in the Wild (LFW) dataset”. That is almost at the brink of human level accuracy!

In this article, I am going to informally evaluate a new application Facebook is putting its algorithms into. A few months ago, Facebook announced that to aid the perception of photos by differently abled users who have impaired eyesight, it is going to add detected features in the alt-text of images which can then be used by text-to-speech applications to describe the image contents.

Photo tagging abuse : A chagrin of social media

Although the word “tagging” was not coined by social media, yet today it has become quite commonplace, thanks to the mass acceptance and popularity of sites like Facebook and Instagram. We take group photos, upload them on these sites, share them with out friends, but we don’t stop there. We tag the people in them!

Tagging ensures that our friends get to know that we have uploaded their photo, allows our own friends to recognise others and get to know whom we spent those awesome moments at the beach with. But it also serves another purpose – it gives us a larger audience who gets to see the photo on their news feed. And some of these strangers are sure to “like” and “comment”, aren’t they?
