    abstract = {The primary objective of steganographic techniques is to conceal a secret message in an
innocent-looking cover media. One of the well-known techniques is Least Significant Bit (LSB) algorithm which
is used in many information security applications. This current study presents an efficient solution to improve
the security level of the standard LSB. The recommended solution combines two techniques; the standard LSB
algorithm and the ASCII Mapping Technique (AMT). In the first step, AMT is used to encode the secret
message using an image-key instead of classical stego-key. In the second step, the recursive technique along
with circle equation in parametric polar form are used for embedding the message bits into pixels that are
selected randomly. Furthermore, noise data are embedded into stego-image in order to render the steganalysis
task more challenging. The steganalysis not only has to guess which pixels have been used to hide data but
also must isolate real hidden data from noise. Compared to standard LSB algorithm, the proposed technique
achieves a significant security improvement, higher capacity for hiding data with high image quality.}
