In today's world of developing technology, Multimedia transmission through public network is increasing drastically, so there is a need of fast transmission with data security. Compressive Sensing (CS), is a new approach which can acquire the signal in a compressed form. It dimensionally reduces the signal with the help of measurement matrix. Reduction of dimension is totally dependent on the Sparsity. CS has a feature to reconstruct the signal in lesser than the Nyquist sampling rate if the signal is sparse. In the case of transmission, signal security is also a serious concern. CS has an embedded feature of cryptography. It works as a cryptosystem when measurement matrix is shared as a key between the sender and receiver. CS has a vital scope in medical imaging, video acquisition etc. Many researchers have tried to encrypt the signal with the help of different chaos based measurement matrix. This paper gives a detailed survey and critical analysis on the image encryption techniques using CS which can help the naive researchers to excel the field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
