“…The Zero Watermarking Technique is based on DWT and SVD methods. Also, PSNR (Peak signal to noise ratio) [4] is used to determine the quality of output image which further indicates the peak error. And in the Lossless Watermarking technique, HMAC, a keyed-hash authentication code [3] is used for authentication.…”

With advancement in communication technology, sharing of medical images over the internet is on rise. But with that it is always required to maintain the integrity of the images. Hence it is necessary to develop techniques for authentication. One solution to protect the digital medical images is by Digital image watermarking. This paper reviews different watermarking techniques for authentication of medical images.

“…When receiving medical data, the receiving end can recover the data content non-destructively while extracting the watermark information, thereby ensuring the integrity and authenticity of the data, which helps doctors more accurately judge the patient's condition. Reversible image watermarking can be divided into the following categories: based on compression technology [8], based on differential expansion (DE) [9][10][11], based on histogram shift (HS) [12,13], based on prediction error (PEE) [14][15][16], and based on integer transformation [17,18].…”

The leakage of medical audio data in telemedicine seriously violates the privacy of patients. In order to avoid the leakage of patient information in telemedicine, a two-stage reversible robust audio watermarking algorithm is proposed to protect medical audio data. The scheme decomposes the medical audio into two independent embedding domains, embeds the robust watermark and the reversible watermark into the two domains respectively. In order to ensure the audio quality, the Hurst exponent is used to find a suitable position for watermark embedding. Due to the independence of the two embedding domains, the embedding of the second-stage reversible watermark will not affect the first-stage watermark, so the robustness of the first-stage watermark can be well maintained. In the second stage, the correlation between the sampling points in the medical audio is used to modify the hidden bits of the histogram to reduce the modification of the medical audio and reduce the distortion caused by reversible embedding. Simulation experiments show that this scheme has strong robustness against signal processing operations such as MP3 compression of 48 db, additive white Gaussian noise (AWGN) of 20 db, low-pass filtering, resampling, re-quantization and other attacks, and has good imperceptibility.
