{"Image DocumentName": "SteganographyWe conclude with a discussion of a technique that (strictly speaking), is not encryption,", "Image ImageDescription": "namely, steganography . A plaintext message may be hidden in one of two ways. The methods of. steganography conceal the existence of the message, whereas the methods of. cryptography render the message unintelligible to outsiders by various transformations. of the text. A simple form of steganography, but one that is time-consuming to construct, is one in which an arrangement of words or letters within an apparently innocuous. text spells out the real message. For example, the sequence of first letters of each. word of the overall message spells out the hidden message. Figure 2.9 shows an. example in which a subset of the words of the overall message is used to convey the. hidden message. See if you can decipher this; it\u2019s not too hard.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
