摘要
当前,基于图像LSB的隐藏算法已经成为一种主流的信息隐藏技术。根据LSB隐藏将导致图像空域像素区内LSB长游程长度偏移(减小)的特点,本文提出了能够度量这种偏移的游程检测算法,并给出了算法原理和实现方法。该算法基于盲检测、不需要训练图像数据库、在满足一定假设条件下,检测性能优良而且算法简单易于工程实现,具有一定的实用价值。
Information hiding technique using LSB algorithm based images has become a main steganography the basis of the characteristic that LSB hidng in spatial domain of image can cause some offset（reducing） of the length of long Run - length , this paper describes a Run - length detecting algorithm and gives the principle and realization of the algorithm. Under certain assumptions , the algorithm based blind detection is practical , effective, easily achieved and need not training image database.
