Large Amount of Multi Media Transmission using QR-Code

Abstract

Quick Response (QR) code may be a two-dimensional (2D) barcode widely used in many applications such as producing, advertising, marketing etc. QR code sounds like a noisy structure. And of QR code are often improved by embedding an information data as well as audio into the code. This survey planned a technique where the looks of QR code consists of visually significant patterns chosen by users. Multimedia security represents a class of processes accustomed embed knowledge, adore copyright data, into numerous sorts of media such as image, audio, or text with a minimum amount of information to compress to the “host” signal; i.e., the embedded information ought to be invisible to an unknown human observer. In this survey study about activity in QR code techniques for data hiding and audio compressions, audio to text voice communication, extraction information from QR code and study related the different techniques of that. For text compression, we tend to use totally {different completely different} techniques and for audio to text voice communication, we tend to use different ways. The audio embedding within the QR code is not a simple task because embedded result should be decodable by normal secret writing applications and can be applied to any audio with full area coverage.
