Dự án “Your Face is Big Data” (Khuôn mặt của bạn là Dữ liệu lớn) của nhiếp ảnh gia Egor Tsvetkov là một ý tưởng thông minh nhưng khá đáng sợ bởi tính riêng tư giờ đây dường như không còn nữa.
Nhiếp ảnh gia Egor Tsvetkov đã cho thấy hoàn toàn dễ dàng cho những người lạ có thể thu thập thông tin về bạn. Egor đã dành 6 tuần để chụp khoảng 100 bức ảnh của những người đi tàu điện ngầm ở thành phố St Petersbourg và sau đó sử dụng phần mềm nhận diện khuôn mặt FindFace để tìm kiếm những người này trên mạng Internet.
Nhiếp ảnh gia người Nga đã sử dụng phần mềm mã nguồn mở để quét 55 triệu người dùng trên Vkontakte, mạng xã hội lớn nhất của Nga, và có thể nhận diện được khuôn mặt của cả những người có rất ít điểm giống nhau trên các hình ảnh trên Internet. Egor cho biết đã có thể tìm được 70% số người anh đã chụp.
“Dự án của tôi nhằm mục đích cho thấy tương lai như thế nào sẽ chờ đón chúng ta nếu chúng ta tiếp tục tiết lộ quá nhiều về mình trên Internet”.
Trong một thời đại mà người dùng sử dụng mạng xã hội nhiều hơn bao giờ hết như bây giờ thì có lẽ đã đến lúc chúng ta nên suy nghĩ sẽ chia sẻ những thông tin gì với cả thế giới.

Revealed: How facial recognition can expose your life to strangers
Afacial recognition app that can work out the identities of strangers in a crowd by matching their faces with profiles on social media is taking Russia by storm.
In just two months FindFace has gathered 500,000 users who have run nearly 3 million searches, according to its founders.
The technology gained international attention when a photographer used it to create an art project that revealed just how much information strangers can gather about you with a picture of your face.
Russian photographer Egor Tsevtkov wanted to know how much personal data he could find out about complete strangers on the underground. With this idea in mind he photographed a selection of strangers, and used a free facial recognition software with terrifying results.
The software he used is a website called Find Face, which lets users look up people online using a photo, and accurately matches them up with a Facebook profile, based on their faces.
"I learnt a lot about a person's life without any contact," said Tsevtkov. "I felt slightly uncomfortable."

"I learnt a lot about a person's life without any contact," said Tsevtkov. "I felt slightly uncomfortable."
"I photographed people who were sitting in front of me in the subway, and then looked for them in social networks using open source software," said Tsevtkov, who called the resulting project called "Your face is Big Data".
Tsvetkov uploaded the images taken on the underground and waited as the site scoured Russian Facebook rival VKontakte, which has at least 55m users, for matches.
Through Find Face, Tsevtkov found the profile pages of at least 24 people. With their profiles he was able to understand personal details about their lives, including their hobbies, professions, relationship status and eating habits.
"I was feeling creepy, because when you learn a lot about somebody's private information like family, or work, or pets you see them in another way," he said.

The facial recognition technology used to track down Tsevtkov's subjects is widespread and increasingly accurate. It has been used by Facebook to auto-tag photos and Google to recognise who's in a picture.
Facial recognition can have security benefits, for example in law enforcement databases. But it can also exploited for commercial value: Tesco installed the technology in cameras across 500 stores so that it can map the demographic patterns of its customers, such as their age and gender.
"This experiment highlights the disconnect between individuals believing they are sharing personal information and pictures only with friends, family, and colleagues, when in reality such information is virtually public," said Christopher Weatherhead, a technologist for Privacy International. "It is critical that we should retain control of the information we put online."

Short of hiding your face whenever you're out in public, which isn't as easy in dreary Britain, there's not a lot you can do to prevent someone from taking a picture of you and looking you up online. But you can restrict how much of your personal information is available publicly online.
One way to prevent strangers from being able to find out similar private information about you is to update your privacy settings on Facebook. You can also restrict who can view your Instagram pictures and Twitter posts, making sure that only people you know can see your most personal online details.
