Yovo: No way to keep the chat log software

Now the privacy problem is very serious, you chat when you are afraid of people know chat record? Today small series for everyone recommend a very careful protection of user privacy software, named Yovo. An application named Yovo aims at the market where the software is burned by Snapchat, and the software's biggest feature is that there is no way to save chat records or private pictures through screenshots, which can better protect users ' privacy than Snapchat. Yovo in the iOS app Store in Wednesday and has no Android version yet. Like Snapchat and other burnt applications, Yovo allows users to send photos to friends, and friends have a limited amount of time to view them before they are automatically deleted. But Yovo's biggest difference is that it has a feature called D-fence, which allows users to try screenshots or use a camera to photograph a mobile phone screen with opaque vertical stripes on the picture. This free application was developed by the ContentGuard developer, a company that previously focused on confidential document-sharing software. Scott Richardson, ContentGuard's product director, said the company wanted to develop a privacy-oriented social application, like Snapchat and Wickr; not like Instagram, Anyone can see and store your uploaded photos. Richardson also said application developers realized early on that they needed a way for users to have no way to save pictures through screenshots. If you can save a picture with a screenshot, then the private application will not be able to talk about it. Yovo's solution uses the visual perception of the characteristics of the occlusion in front of the photo of the opaque vertical stripes will disappear according to a certain frequency and appearance, such a way to ensure that users can clearly see the picture content, but also to ensure that the screen can not be saved by screenshots. Of course, Yovo can also send fully visualized photos, depending on whether the user chooses to use the D-fence feature when sending photos. Richardson tells us that these vertical stripes move across the image quickly, so it looks like you can see the whole picture, but if someone wants to save those images protected by a screenshot or by using another camera, they will only get blurry pictures. This application can generate a URL for the picture, which users can share by email, SMS, Facebook and Twitter, and the images that are shared are still protected. With Yovo this more focused on user privacy applications, the existing Snapchat users will consider migrating to Yovo, and how Snapchat will respond to the challenges that are imminent, worthy of our expectation.
