Practical Privacy-Preserving in Cloud Image Repositories

Abstract

Cloud computing is an emerging technology utilized widely due to its various advantages. However the major issue faced here is security in maintaining files. Our proposed work focuses on storing and retrieving of image data in secure way in cloud through double step verification. In general, cryptography is utilized to store data in secure way. The key logic is when there is less security automatically data will be reveal to unauthorized users. In our proposed method, these issues are overcome through double step verification. Initially image has been encrypted through Attribute Based Encryption (ABE). In addition to provide better security repository encryption has been implemented by RC4 approach. This will provide better security for user data in cloud through this two step verification. To ensure originality of user image watermarking technique has been implemented. Therefore it ensures without user knowledge an unauthorized user could not get the original image. Hence our system achieves maximum security compared to other existing approaches.
