Transmission of biomedical images over long distance is very important for various applications like telemedicine and distant consultation with health experts.Many of these images carry confidential information and need to be highly secured before transmission.For the purpose of secured transmission, images must be encrypted.Hence, an efficient technique for secured communication of biomedical images is proposed in this communication, which is applicable equally for all types of images.In this communication, the algorithm is applied on mammogram images for detection of breast cancer.Security of transmitted images is enhanced by application of Fractional Fourier Transform (FRFT) and 3D Rabinovich Chaotic map.The algorithm shows satisfactory result for applications where image data are to be transmitted in highly secured way.
