In this paper, novel proof of retrieval (POR) and proof of ownership (POW) protocols for images based on the use of the SPIHT compression algorithm are proposed. The POR protocol can be run by the users to ensure that their images are stored securely in the cloud, and the POW protocol can be run by the cloud storage provider (CSP) to authenticate the true owner of the images. The efficiency of our scheme relies on the fact that only a fraction of the compressed data is used for encoding the images. Experimental results are provided to validate the stated goals.
