Audio Watermarking is useful technique for audio systems. This technique can work on different domains like frequency and time. By using the different scheme of watermarking at different levels of audio, it can be secure from many types of attacks. This paper shows some techniques which can be used to secure the audio system from attacks and survey on(More)
There are a number of algorithms which provide methods to encrypt parts of video frames to make them unrecognizable or degraded. The proposed scheme treats the video as a sequence of ordered frames and provides an algorithm to break this order of frames by first distributing frames into n frame-sequences and then by internally scrambling these(More)
Stochastic search algorithms that take their inspiration from nature are gaining a great attention of many researchers to solve high dimension and non – linear complex optimization problems for which traditional methods fails. Shuffled frog – leaping algorithm (SFLA) is recent addition to the family of stochastic search algorithms that take its inspiration(More)
A method to protect video contents from unauthorized access is known as a video encryption scheme. This paper first surveys the literature to identify most desired features of an encryption algorithm. Then a classification has been drawn according to their characteristics. After that, some of the algorithms are discussed and their working has been explained(More)
