A Digital Watermarking Algorithm Based on DCT: Application on Medical Image

subject

description

International audience; This work is a presentation of a new approach of robust watermarking applied in medical domain such as telemedicine hence the need to keep the visual aspect of medical images and other conservation of the various data substituted. For hiding information, the proposed method uses the Discrete Cosine Transform (DCT) space. To control identification and eventually the correction (if possible) of the data inserted, it should be noted that we used the series turbocode to recover the data inserted and after application of several attacks.
