Scalable Secure MJPEG Video Streaming

Abstract

In today's world, more and more applications are developed for mobile devices and ever-increasing amount of communication happens over mobile devices and mobile networks. Though providing mobility and convenience, mobile devices generally do not offer intensive computations like their wired counterparts. In this paper we propose a set of methods that aims to protect video, specifically Motion JPEG (MJPEG) video streams, using selective data encryption. More precisely, our algorithm selects the most critical pixel information of MJPEG video as the input of encryption to keep itself lightweight while choosing and encrypting additional less-important video information when the environment allows. The proposed method was originated from the fact that JPEG images are encoded using prioritized pixel information. Experiment results show that the proposed algorithm performs well in terms of frame rate and CPU load at playback.

Technical vision system for the robotic model of surface vessel

“…Координаты реального надводного судна в открытом водном пространстве определяются с помо-щью систем глобального позиционирования (GPS, ГЛОНАСС). Использование подобных систем в соста-ве робототехнического комплекса невозможно в силу ряда причин [1][2][3][4][5]. Это связано с малыми размера-ми модели, в результате чего погрешность определения координат превышает разумные пределы.…”

Performance evaluation of matrix- and EXIF-based video rotation methods in MJPEG-based live video encoder

“…In our experiments, we use MJPEG (Motion JPEG) [11,12,13] as a video encoding format. MJPEG was chosen for two reasons: its straightforward implementation on Android platform, which is a test platform in our experiments, and its broad client-side support.…”

“…MJPEG (Motion JPEG) [11,12,13] is a video compression format that is nowadays widely used by various video-capture devices, such as digital cameras, IP cameras in video surveillance settings, and webcams. MJPEG is also streamable over the HTTP [14,15] and natively supported by Safari, Google Chrome, and Mozilla Firefox web browsers, as well as several standalone video players.…”

A Comparative Study of Video Encryption Schemes

“…This algorithm [23] is applicable to MJPEG format only as it does not use inter-frame correlation. Authors propose four categories of encryption according to the amount of encryption done.…”
