The rise of scientific achievements and the development of medicinal discoveries make computer techniques and internet communication very important for telemedicine and healthcare. A large amount of information is being generated from hospitals and medicinal centers. Huge information needs big memory and an efficient transmission method. There must exist an efficient technique for the realization of transforming the data and an effective memory storage mechanism for large data. In order to the safe transfer of medicinal data represented by images and medicinal signals, and in order to protect medicinal image data during transmission, to ensure that the decryption is not possible, A secure method was used to compress these images using JPEG image compression, and then encrypt these images using RC4 encryption method to preserve the medicinal data from changes that may occur to it or tampering with its contents from an external source. The new image compression method, as well as the encryption of its medicinal data, has proven based on the parameters; "Compression Ratio CR", "Compression Time CT", "Mean Square Error MSE", and "Peak Signal to Noise Ratio PSNR" its efficiency in the transfer process by reducing its size to the lowest possible size without affecting its important medicinal data for Telemedicine purposes.
