Secure Data Hiding in Coded Image using Arduino Speech Recognition

Abstract

The cover medium is used as an envelope to hide inside information. Embedded data may represent a text, image or video to be transferred in the spread media. In this paper, secret information hiding in coded image is exhibited relying upon quantization level and discrete wavelet transform (DWT). Secret data is encrypted and controlled by Arduino speech recognition board in both transmitter ad receiver side to decrypt these secret data. The color image is utilized as a cover image with the discrete wavelet transform it into another form and Absolute Moment Block Truncation Coding (AMBTC) technique is used for embedding the data. The mapping of secret data and image scrambling is depended on the Henon map, while the logistic map is used to encrypt secret data. The proposed method achieved accurate results in peak signal to noise ratio about 34.0524 at average for tested image.
