A new chaos based medical image encryption scheme

Image encryption has great importance in transmitting images securely for numerous applications taking the advantages of modern communication networks. Due to the era of modern technology medicine sector has updated in dramatic way such as the concept of telemedicine, more specifically the tele radiology services, has raised a great deal of concerns in the security of medical images transmitted over open networks. In order to meet the necessary challenge, a new chaos based encryption scheme is proposed with emphasis on stronger security with variable control parameter facility in a simplistic way. Thorough experimental tests are carried out and the obtained results have shown satisfactory performance which means proposed scheme provides an effective way for online secure medical image transmission over public networks.
