Proof of ownership for deduplication systems: A secure, scalable, and efficient solution

Computer Communications, 2016
Abstract Deduplication is a technique used to reduce the amount of storage needed by service providers. It is based on the intuition that several users may want (for different reasons) to store the same content. Hence, storing a single copy of these files would be sufficient. Albeit simple in theory, the implementation of this concept introduces many

Proof of Retrieval and Ownership Protocols for Images through SPIHT Compression

2014 IEEE Intl Conf on High Performance Computing and Communications, 2014 IEEE 6th Intl Symp on Cyberspace Safety and Security, 2014 IEEE 11th Intl Conf on Embedded Software and Syst (HPCC,CSS,ICESS), 2014
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 ...

Concurrently-secure credential ownership proofs

Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007
We address the case in credential systems where a credential owner wants to show her credential to a verifier without taking the risk that the ability to prove ownership of the same (and any other) credential is transferred to the verifier. We define credential ownership proof protocols for credentials signed by standard signature schemes.

Proofs of Ownership and Retrievability in Cloud Storage

2014 IEEE 13th International Conference on Trust, Security and Privacy in Computing and Communications, 2014
With the development and maturity of cloud computing technology, the demand for cloud storage is growing. Deduplication is a basic requirement for cloud storage to save storage space of cloud servers. And as clients are untrusted from the perspective of the server, the notion of Proofs of Ownership (PoWs) has been proposed in client-side deduplication.

A proof of copyright ownership using moment-preserving

Proceedings 24th Annual International Computer Software and Applications Conference. COMPSAC2000, 2002
A technique for proving copyright ownership of images is proposed. We use the moment-preserving to represent the characteristics of images. The secret key for copyright detection is generated from the image's feature and the owner's watermark/trademark. This strategy for a watermarking system is wholly different from traditional work.

Zero-Knowledge Watermark Detection and Proof of Ownership

2001
The goal of zero-knowledge watermark detection is to allow a prover to soundly convince a verifier of the presence of a watermark in certain stego-data without revealing any information which the verifier can use to remove the watermark. Existing proposals do not achieve this goal in terms of definition (not formally zero-knowledge), security (unproven)

Towards Proofs of Ownership Beyond Bounded Leakage

2016
Cloud servers save their storage cost by applying deduplication. Duplicated copies of the same file uploaded by the cloud service clients can be reduced to a single copy by maintaining a list of clients who own the same file. Nowadays it is a common practice to rely on the message digest of the file for showing its possession.

Anticounterfeiting in Pharmaceutical Supply Chain by establishing Proof of Ownership

TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019
Drug counterfeiting is a serious and increasing critical issue worldwide, which puts the health of consumers and the general population at risk. WHO estimates that the world's counterfeit drug market make billions of dollars annually. It is due to the inadequate supply chain in the developing countries that one in the drug is counterfeit.

Secure and efficient proof of ownership for deduplicated cloud storage

Proceedings of the 10th International Conference on Security of Information and Networks, 2017
The rapid increment in volume of outsourced data has raised an issue of data management for Cloud Storage Server. To solve this issue, Deduplication, a data compression technique was introduced which avoids duplicate data storage. However, Deduplication is vulnerable to malicious access to genuine Cloud Clients' files.
