A survey on Privacy Preserving The Data Privacy And Copyrights During Image Retrieval in Cloud

Abstract

Current generation uses the images and photosmore than the text messages. Images consume more time and space than the text messages for both retrieval and storage respectively. Hence there is a need for efficient storage and retrieval of images. Cloud computing is the best choice for cloud storage outsourcing. So that the image owner can directly outsource the images to the cloud rather than maintaining local image database. In order to preserve the privacy of confidential images like personal and medical images, it has to be encrypted first before outsourcing it to the cloud. Next in order to access the encrypted images in cloud we use a technology called content based image retrieval. In this paper we use standard block cipher for image encryption and for copy-deterrence and privacy preserving purpose, watermark is embedded to the retrieved images.
