This paper presents several proposed scenarios for medical image transmission over Wireless Multimedia Sensor Networks with multi-level security tools and Unequal Error Protection (UEP) technique to provide highly secure and improved medical images transmitted over the wireless link. The proposed scenario is based on embedding the medical images with audio watermarking technique. The audio signal is presented as a medical report for the embedded medical image. The audio watermarking in this paper used the Singular Value Decomposition technique to hide the image as a watermark into the audio cover signal to form the watermarked signal. This combined signal is transmitted using the UEP technique by employing different error control schemes and different packet lengths to enhance the quality of extracting encrypted/unencrypted medical images. The results show that the quality of the extracted medical images with encoded packets is better, also, the encryption of different error control schemes employing with the image enhances the extracted image and its quality.

本文介绍了几种通过多级安全工具和不等错误保护（UEP）技术在无线多媒体传感器网络上进行医学图像传输的方案，以提供高度安全和改进的通过无线链路传输的医学图像。所提出的方案是基于使用音频水印技术嵌入医学图像的。音频信号作为嵌入式医学图像的医学报告呈现。本文中的音频水印使用奇异值分解技术将作为水印的图像隐藏到音频覆盖信号中，以形成水印信号。通过采用不同的错误控制方案和不同的数据包长度，使用UEP技术发送此组合信号，以提高提取加密/未加密医学图像的质量。
