Description: 图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string, however, one byte for each data bit is not an important degree of the same, often only two adjacent low-byte is not the same. For example: 00100110 and 00100111 represent the gradient of two different degrees of red, but on the human eye is not out to tell. Least significant bit LSB algorithm, is to take advantage of this point, to achieve image compression, or digital watermark feature.

Description: technique is quite small owing to the low compression ratio. Based on this, a general least significant
bit-plane (LSB) embedding technique in the spatial domain was proposed by Celik et al. [6]. The payload and
imperceptibility of embedded data are largely improved because of the more efficient compression technique.
Domingo-Ferrer et al. [5] proposed a spread spectrum data hiding method that is only reversible with respect
to the modified version of the original host signal . Xuan et al. [7] proposed a reversible data hiding algorithm
carried out in the integer wavelet transform (IWT) domain. An improved version of this algorithm was
reported in [11]. By exploiting the superior features of wavelet transform, in particular, the high decorre-technique is quite small owing to the low compression ratio. Based on this, a general least significant

Description: Nowadays, with the rapid growth in formation technology more and more images and data are available on the internet. So there is a need to provide some kind of authentication to such important data. When the sender transmits the image to the receiver, there may be intruders present in between who may capture the image. After capturing the image the mage the intruder may view the meaningful content in the image. This may not be the problem in some cases. But if we consider security applications like medical and military images then such distortion is unacceptable. To avoid misuse or loss of information several reversible data hiding techniques (RDH) are implemented. This paper gives details on watermarking, LSB, Histogram and RDH using optimum Thresholding with related results.-Nowadays, with the rapid growth in information technology more and more images and data are available on the internet.

Description: LSB Hiding : Advanced encryption standard (AES) that has been
proposed by National Institute of Standards and Technology
(NIST) plays a significant role of a secure algorithm for
data exchanged. Two prime processes involved: encryption
(cipher) and decryption (decipher). Cipher is a process
to convert data into unintelligent form called ciphertext.
Similarly decipher is a process for the data to be converted
back into its original form called paintext.
