Advances in blockchain technology have led to new applications that aim to eliminate central systems, to improve transparency and user control in transactions whiledealing with the privacy and security challenges. In this thesis, a system which enables users to control their private data and to share chosen data to other parties usingsecure computation techniques is reviewed. Then, we present a blockchain-based digital identity system depending on this architecture. This system ensures that identity information is shared and transmitted confidentially in accordance with their own consent.

A Fully decentralized framework for securely sharing digital content
Demir, Ahmet Serhat; Acar, Aybar Can; Department of Cyber Security (2019)
Blockchain is a secure, immutable, and distributed public ledger that stores transactional data. It enables information transfer without the need for a trusted third party via its decentralized consensus mechanism. Besides finance, blockchain technology has the potential to change several industries, through smart contracts and decentralized applications. This thesis explores using blockchain technology, smart contracts, and Ethereum Web 3.0 stack for secure information and file sharing on a fully decentral...
Topology-Aware Cooperative Data Protection in Blockchain-Based Decentralized Storage Networks
Yang, Siyi; Hareedy, Ahmed; Calderbank, Robert; Dolecek, Lara (2020-06-01)
The continuous rise of the blockchain technology is moving various information systems towards decentralization. Blockchain-based decentralized storage networks (DSNs) offer significantly higher privacy and lower costs to customers compared with centralized cloud storage associated with specific vendors. Coding is required to retrieve data stored on failing components. While coding solutions for centralized storage have been intensely studied, those for DSNs have not yet been discussed. In this paper, we pr...
Smart water chain: Immutable, distributed and decentralized water transaction ledgers
Satilmisoglu, Talat Kemal; Keskin, Huzur (2023-01-01)
Blockchain is a transactional data storage system where data can be stored reliably without the need for a central database or trusted authority. The data can be anything like financial transactions, supply chain processes or medical records. It is similar to a classical database but uses a decentralized ledger and allowing each participant in the network to have their own copy of the ledger and be able to see all transactions. Data stored in the distributed ledger can only be read or written, not deleted o...
Analysing Opportunities and Challenges of Integrated Blockchain Technologies in Healthcare
Gökalp, Ebru; Gökalp, Mert Onuralp; Eren, Pekin Erhan (2018-09-20)
Blockchain is a disruptive technology with the potential to have a significant impact on business models and industries, similar to the adoption of Internet. Blockchain promotes distributed, open, inclusive, immutable, and secure architectural approaches, instead of centralized, hidden, exclusive, and alterable alternatives. The adoption of blockchain in the healthcare domain offers promising solutions for securing communications among stakeholders, efficient delivery of clinical reports, and integrating va...
Distributed Content Based Video Identification in Peer-to-Peer Networks: Requirements and Solutions
Koz, Alper; Lagendijk, R. (Inald) L. (2017-03-01)
In this paper, we first discuss the essential requirements for a fingerprint (perceptual hash)-based distributed video identification system in peer-to-peer (P2P) networks in comparison with traditional central database implementations of fingerprints. This discussion reveals that first, fingerprint sizes of existing video fingerprint methods are not compatible with the cache sizes of current P2P clients; second, fingerprint extraction durations during a query are not at tolerable levels for a user in the n...
