摘要

“在数字时代,保护机密信息的隐私是身份验证和秘密通信的关键问题。密码术、隐写术、数据匿名化是用来保存信息的几种技术。隐写术是将信息隐藏到其他非秘密信息源(如文本、图像或音频)中,使秘密信息肉眼不可见的过程。本文提出了一种新的基于素数的嵌入(PNBE)方法来实现有效的数据隐藏,从而在不产生视觉失真的情况下对图像中的数据进行编码。该方法提出了一种识别图像中数据嵌入位置的新方案,并提出了一种用于消息编码和解码的PNBE算法。用基准图像对该方法进行了验证。在不同大小的图像上测试了数据的编码容量和质量。实验结果表明,基于图像大小,该算法的隐藏容量在6327 ~ 12448字节之间。图像的质量被描述为峰值信噪比(PSNR),它计算原始图像和压缩图像之间的质量差。用更高的PSNR值验证了该方法的有效性。从结果中可以看出,所提出的方法在嵌入容量和图像质量方面优于现有方法。

A Data Hiding Approach for Secured Data Communication
"In the digital era preserving the privacy of confidential information is the crucial issue in authentication and secret communication. Cryptography, steganography, data anonymization are few techniques used to preserve the information. Steganography is the process of hiding information into other non-secret sources of information like text, image or audio, so that secret information is not visible to the naked eye. This paper proposes a novel Prime Number Based Embedding (PNBE) approach for efficient data hiding to encode the data in images without any visual distortion. This approach proposes a novel scheme for identifying the embedding location of the data in the image and PNBE algorithm for the encoding and decoding of messages. The proposed approach is demonstrated with benchmark images. The data encoding capacity and quality are tested on different sized images. Experimental results show better hiding capacity in terms of bytes ranging from 6,327 to 12,448 based on the size of the image. The quality of the image is described as Peak to Signal Noise Ratio (PSNR), which computes the quality difference between original and compressed images. The efficiency of the proposed approach is demonstrated using PSNR with higher values. It is observed from the results that the proposed approach outperforms the existing ones in terms of embedding capacity and quality of the images. "
