Cloud security using Biometric authentication and 6D Hyper Chaotic System

Nowadays, cloud computing is more frequently used to store data, especially digital images. The security of digital images in the cloud is very crucial. Here in this research paper, a technique is proposed to secure the cloud images. Biometric authentication makes our scheme more powerful in the security aspects. The proposed scheme uses the user's fingerprint to provide much more protection to digital images which are stored in a cloud network in encrypted form by using a 6D hyperchaotic map. To access the images, first user has to verify himself by using his fingerprint then a reverse encryption process is performed to get the decrypted images. Different types of security analysis tests are performed to check the robustness of the proposed encryption scheme. Experimental results show the robustness and efficiency of the technique.
