DOI: 10.1007/s11042-019-08112-z
Abstract: Image encryption is very different from that of texts due to the bulk data capacity and the high redundancy of images. Thus, traditional methods are difficult to use for image encryption as their pseudo-random sequences… read more here.

DOI: 10.1007/s13369-019-04272-0
Abstract: In this paper, we propose a LSB steganography algorithm to hide pseudorandomly sensitive information in digital images. This algorithm affects the statistic features of the sensitive information before it is embedded in the cover image.… read more here.

DOI: 10.1007/s40840-017-0505-9
Abstract: This note investigates the conjugacy from Farey map to the skew tent map. We present two explicit expressions of the conjugacy with two kinds of representations for real numbers, and estimate the Hölder exponent of… read more here.
