With the widespread growth of digital information and improved internet technologies, the demand for improved information security techniques has significantly increased due to privacy leakage, identity theft, illegal copying, and data distribution. Because of this, data hiding approaches have received much attention in several application areas. However, those approaches are unable to solve many issues that are necessary to measure in future investigations. This survey provides a comprehensive survey on data hiding techniques and their new trends for solving new challenges in real-world applications. The notable applications are telemedicine, 3D objects, mobile devices, cloud/distributed computing and data mining environments, chip and hardware protection, cyber physical systems, internet traffic, fusion of watermarking and encryption, joint compression and watermarking, biometric watermarking, watermarking at the physical layer, and many other perspectives. Further, the potential issues that existing approaches of data hiding face are identified. I believe that this survey will provide a valuable source of information for finding research directions for fledgling researchers and developers.

数据隐藏

随着数字信息的广泛发展和互联网技术的改进，由于隐私泄露、身份盗用、非法复制和数据分发等原因，对改进信息安全技术的需求显着增加。正因为如此，数据隐藏方法在多个应用领域受到了广泛关注。然而，这些方法无法解决许多在未来调查中需要衡量的问题。本调查对数据隐藏技术及其解决实际应用中新挑战的新趋势进行了全面调查。值得注意的应用是远程医疗、3D 对象、移动设备、云/分布式计算和数据挖掘环境、芯片和硬件保护、网络物理系统、互联网流量、水印和加密的融合、联合压缩和水印、生物特征水印、物理层水印和许多其他方面。此外，确定了现有数据隐藏方法面临的潜在问题。我相信这项调查将为初出茅庐的研究人员和开发人员寻找研究方向提供宝贵的信息来源。
