Abstract

In today's scenario, one of the biggest challenges facing computer users is how to secure data on a personal computer or in any communication. Various forms of data security and hiding algorithms have been developed in the last decade. Cryptography and steganography are known familiar security methods to be used for hide sensitive data. In this paper, we have developed a data hiding method in images with three security layers. The first layer is compression to reduces the redundancy in data representation, i.e. to decrease the storage capacity required for that sensitive data. The second layer is cryptography using the Advance Encryption Standard (AES) to make the compressed data unusable. The third layer hides the data in the 2 least significant bits (LSB) of images presenting high 3-layers security scheme. The results proven interesting outcomes compared to other methods. This 3-layer technique is showing promising research direction for further text security developments to be coming in the future.

3层PC文本安全通过组合压缩,aes加密,2lsb图像隐写
在当今的情况下,计算机用户面临的最大挑战之一是如何保护个人计算机或任何通信中的数据。在过去的十年中,各种形式的数据安全和隐藏算法被开发出来。密码术和隐写术是常用的用于隐藏敏感数据的安全方法。在本文中,我们开发了一种具有三个安全层的图像数据隐藏方法。第一层是压缩,以减少数据表示中的冗余,即减少敏感数据所需的存储容量。第二层是使用高级加密标准(AES)使压缩数据不可用的加密技术。第三层将数据隐藏在图像的2个最低有效位(LSB)中,提供高的三层安全方案。与其他方法相比,结果证明了有趣的结果。这种三层技术为未来进一步的文本安全发展显示了有希望的研究方向。
