Information security is major concern in modern digital ages, and the outdated algorithms need to be replaced with new ones or to be improved. In this article a new approach for hiding secret text message in color images is presented, combining steganography and cryptography. The location and the order of the image pixels chosen for information embedding are randomly selected using chaotic pseudo-random generator. Encrypting the secret message before embedding is another level of security designed to misguide the attackers in case of analyzing for traces of steganography. Evaluating the proposed stegoalgorithm. The standard statistical and empirical tests are used for randomness tests, key-space analysis, key-sensitivity analysis, visual analysis, histogram analysis, peak signal-to-noise ratio analysis, chi-square analysis, etc. The obtained results are presented and explained in the present article.

具有随机选择像素顺序和加密文本消息嵌入的彩色图像中的隐写术

信息安全是现代数字时代的主要关注点，过时的算法需要用新的算法代替或加以改进。在本文中，提出了一种将隐秘术和密码术相结合的在彩色图像中隐藏秘密文本消息的新方法。使用混沌伪随机发生器随机选择用于信息嵌入的图像像素的位置和顺序。在嵌入之前对秘密消息进行加密是另一种安全级别，旨在在分析隐匿痕迹的情况下误导攻击者。评估拟议的隐秘算法。标准的统计和经验测试用于随机性测试，键空间分析，键敏感度分析，视觉分析，直方图分析，峰信噪比分析，卡方分析等。
