A picture is worth a thousand words

Ever wanted to remember forever the crazy atmosphere of Saturday party with your friends? The liberating moment when you graduate? The cuteness of your cat chasing a laser beam? In most of those cases, you would take a picture or record a video in order to store this memorable instant. Visual multimedia have become an inseparable part of our social lives, and they often capture moments tied to deep affections.

Unstructured data (images, video) are taking over structured data in the past few years

Everything in the palm of your hand

Meanwhile, the famous Moore’s law is at work (even though some are questioning its existence today). Chips keep shrinking at a formidable rate, and, alongside the information revolution, you can now carry in your pocket a computer a million times more powerful than Apollo’s space shuttle. Another striking example is that most recent phones are actually now almost as powerful as their contemporary laptops!

User privacy at the forefront

The advent of mobile devices came with a curse, security. Protecting user privacy and the access to these numerous devices has become a primary concern. Services storing user data on their server are particularly exposed. For example, Yahoo! disclosed a breach of all their 3 billions accounts, (not 1 billion as initially estimated) including telephone numbers, dates of birth, password and more. No matter the sector, data that are centralised are exposed to potential hacks, whether you are a dating website, an entertainment company, or even the department of defense of the United States. Similarly, ill-protected devices can be used for malicious purposes. In September 2016, the world’s largest DDoS (Distributed Denial of Service) attack to date used around 150 000 compromised connected devices (CCTV cameras and personal video recorders) against OVH, a French web host provider. And the list continues.

Resurrect your memories

The ambition of Zyl is to take advantage of state-of-the-art computer vision algorithms to bring back to life your best memories buried in your phone. Wouldn’t it be easier to enjoy them by finding a precise moment easily? group automatically your pictures by album? or finding the best portraits of your friends? Such features require deep learning technics brought directly to the user, while everything should stay on his or her mobile. All your photos belong to you, and only you. In an upcoming post, we will explain in more details the kind of technologies we use at Zyl to achieve such functionalities.
