Secure and Private Live Video Broadcast
Abstract
Smartphones are becoming increasingly popular and are being used by over 5 billion people worldwide. It is expected that smartphones will replace digital devices like laptops and personal computers in the near future. Smartphones are being continuously enhanced using various technologies such as GPS, front and rear facing cameras, microphone, and always-on Internet connection. With the increase in the usage of smartphones, exchange of information among people has become more convenient. Multimedia is an important type of content, which includes sound and video. Multimedia applications allow a user to share videos, which is an extremely powerful way to convey information as it incorporates a personal touch that other types of media lack. The advantage of integrating video into a multimedia application makes the user effectively convey a great deal of information in a short amount of time. With the introduction of newer and more powerful generation of handheld devices, along with always-on Internet, developing mobile applications that make use of these advancements is one area that has immense potential with very limited research done in it. In this paper, we propose a model to develop an easy to use mobile app for users to broadcast live video.Our mobile app, VidNow, provides privacy to the end user by encrypting the live video end-to-end and also allows the sender of the video to decide whether the receiver can save the received video to disk. A thin lightweight server is used to validate users and to send push notifications to users. As VidNow is mobile-to-mobile, the lightweight server only acts as a repeater to broadcast the live video to potentially millions of receivers. The latency for live video is 650ms on average. VidNow has been submitted to the Apple app store for public release.
