Snapchat is a app that\u2019s swept the world over the past few years, and it undoubtedly provides a lot of entertainment and laughs \u2014 and wonder as to how its technology actually works. But how much can you really trust apps like Snapchat? It must be said that it\u2019s important to use caution when using any apps or websites that learn information about your identity and your actions because some of these apps or websites may be malicious. <\/span><\/p>\n

One of Snapchat\u2019s most advanced \u2014 and exciting \u2014 features are filters. Many of those boast facial recognition, where it turns its user into a different character whenever it\u2019s used. But how does that technology work, and what does Snapchat know about you that you may not have realized? Find out below.<\/span><\/p>\n

Snapchat\u2019s Facial Recognition
\n<\/b>The Snapchat filters that we all adore come from a Ukrainian startup called Looksery, which was acquired for an impressive $150 million by Snapchat. While the company tries to keep it under wraps exactly how their technology works, there\u2019s been research done on the topic.<\/span><\/p>\n

To put it in layman\u2019s terms, the app uses computer vision to spot you based on contrast patterns that can commonly be found in the human face. It uses a general \u201cmap\u201d or \u201cgraph\u201d to find people\u2019s faces and overlay the features of these filters. To make this work, Snapchat trained their system with hundreds or even thousands of different faces, manually marking them where features lay: nose, mouth, eyes, and overall face. That means that when each of us uses the filters on our own faces, the program can use up to 24 frames per second to use its \u201cpoint-mask\u201d to shift to match your specific face.<\/span><\/p>\n

How Much Does Snapchat Know?
\n<\/b>This cool (but slightly creepy) process does pose a question: How much does Snapchat know about us? Should we be taking measures while using the app to protect our identity? While the tool does seem to have a lot of information on us \u2014 our contact list, our name, our location, and even our current activities \u2014 it doesn\u2019t seem that the application can detect too much about us via the facial recognition apps. It may learn more about our facial features and the structure of our face, but it\u2019s not presenting anything too crazy at the moment. This means that we can snap away using these fun and quirky filters without fear.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
