Steganography is the science and art of concealing messages using techniques that allow only the sender and receiver to know of the message?s existence and be able to decipher it. In this article, we would like to present a new steganographic technique for concealing digital images: the Enhanced Segment Compression Steganographic Algorithm (ESCSA)....

Steganography is a science that focuses on concealing messages using specialized techniques so that only the sender and receiver know of the message's existence and are able to decipher it. In this paper, we aim to present a new steganographic technique based on the Karhunen-Loève Transform we have entitled SCSA (Segment Compression Steganographic...

... Table 1 summarizes the data bits position and its corresponding Hamming bits where X value, which denotes a don't care condition, is in a non-sequential or random format. Moreover, the advantage of using Hamming code is it improves robustness [25] and better in performance on networks where the data streams are susceptible to single-bit errors. However, if multiple errors are present, the Hamming codes can detect the errors, but the resultant could cause another correct bit to be altered, causing an additional error to be present on the data as shown in [26]. ...
... For the second set of images, two bits were used in LSB. compression rate is poor for less segmented images, implying that compressed message will not "fit" inside the carrier [13]. It is clear that as number of segments increases, time required will also more. ...
