In computing, the Least Significant Bit (LSB) is the bit position in a binary integer giving the units value, that is, determining whether the number is even or odd. We do not use this format. In conventional Intel bit ordering, the Most Significant Bit (MSB) is numbered 7 and the least significant bit (LSB) is numbered 0: 2⁷ (MSB) 2⁶ 2⁵ 2⁴ 2³ 2² 2¹ 2⁰ (LSB) D = d7 d6 d5 d4 d3 d2 d1 d0 For example, if on the record of number D = 131 = 10000011 we invert the MSB = 1 into MSB = 0, then obtain D = 00000011 = 3, but if we invert LSB = 1 into LSB = 0, then distortions are considerably fewer: D = 10000010 = 130. It is common to assign each bit a position number, ranging from zero to N – 1, where N is the number of bits in the binary representation used. Normally, this is simply the exponent for the corresponding bit weight in base-2 (such as in 2⁷, 2⁶, …, 2¹, 2⁰). In this article to reduce the stego-errors we use a pair of numbers D₁ and D₂ and a pair of corresponding LSB d₁,₀ and d₂,₀.

Metoda steganograficzna na podstawie analizy LSB dwóch sąsiednich próbek danych jednowymiarowych

nr 4

109-116

In this article is elaborated a steganography algorithm on the base on the partly distortion of container LSB with use the two of containers least significant bits, estimated distorting the container at using this method and brought comparing with the method the LSB exchange. It was shown, that the method drawn up was more immune before reading out the message by strange persons, than the existing method of building in stego –message into media data, what show Normalized Cross–Correlation rates to.
