Abstract This paper introduces a robust and secure data hiding scheme to transmit grayscale image in encryption-then-compression domain. First, host is transformed using lifting wavelet transform, Hessenberg decomposition redundant singular value decomposition. Then, we use appropriate scaling factor invisibly embed the of watermark into lower frequency sub-band image. We also suitable improve ...

Advanced data encryption requires the use of true random number generators (TRNGs) to produce unpredictable sequences bits. TRNG circuits with high degree randomness and low power consumption may be fabricated by using telegraph noise (RTN) current signals produced polarized metal/insulator/metal (MIM) devices as entropy source. However, RTN MIM made traditional insulators, i.e., transition met...
