VIDEO SECURITY USING CRYPTOGRAPHY IN CLOUD

It is highly required to secure the video data uploaded on the web cloud serves. Video cryptography (VC) hides the crypto security key on the cipher image on secure images (SI). Video is as sequence of the unsystematic images or frames. Thus, video security is a real tough task to handle because cryptography algorithms for videos must be light weighted to work in real time. A traditional video encryption method offers single type of security and there speed of encryption is also slow. The key features are frequently and outwardly decoded by implying the superimposing of the gifted subset of transparencies or frames, anyway no mystery (cipher) information is gotten from the superposition of a prohibited subset. Paper proposed a Halftone based Video Cryptography (HVC) method using the Floyed dithering halftone process. Proposed HVC based method takes the opportunity to hide the mystery crypto halftone data into shading halftone shares to improve security. The paper proposed an adoptive RGBCMYK based color model for improving the authenticity of the transparencies of crypto security algorithms. These N halftones are used for generating the share data. In meantime the crypto key text of image is embedded into the shading halftone shares. The VC method may be a crypto sharing strategy embedding the mystery crypto image to the transparency frames. The stage vise MSE and PSNR are calculated for the performance evaluation based analysis under the exposure of different noise variances.
