“…The use of blockchain gateways is also proposed in [15], where the setup is tailored for use with IoT scenarios, and, more specifically, with legacy devices. In particular, the user can use the same account for connecting to different blockchain-enabled gateways rather than having to register to each gateway, thus enhancing practicality.…”

In the Internet of Things (IoT) ecosystem, the volume of data generated by devices in the user’s environment is continually increasing and becoming of particular value. In such an environment the average user is bound to face considerable difficulties in understanding the size and scope of his/her collected data. However, the provisions of the European General Data Protection Regulation (GDPR) require data subjects to be able to control their personal data, be informed, and consent to its processing in an intelligible manner. This paper proposes ADVOCATE platform, a user-centric solution that allows data subjects to easily manage consents regarding access to their personal data in the IoT ecosystem. The proposed platform also assists data controllers to meet GDPR requirements, such as informing data subjects in a transparent and unambiguous manner about the data they will manage, the processing purposes, and periods. The integrity of personal data processing consents and the immutable versioning control of them are protected by a blockchain infrastructure. Finally, the paper provides a prototype implementation of the proposed platform that supports the main consents management functionality.

“…There have been many proposals to develop services and systems based on the blockchain technology to take advantage of its properties such as immutability, irreversibility, and decentralization, and many more attempts are underway to utilize the technology [2][3][4][5][6][7][8][9][10][11][12][13][14][15]30,31]. For example, Xia et al presented a platform to configure access control of medical information data through blockchain [7].…”

“…To calculate the ITR from A to B, our model determines a broker X who has the highest DTR product (max(DTR A→X * DTR X→B )) among others who have done transactions with both A and B. Once the broker is determined, ITR is derived according to Equation (9). Figure 3 illustrates an example of ITR calculation between the "user" and the "target", given that there is no direct trust (past transaction) between the two.…”

“…Thus the data stored in blocks eventually become invulnerable to potential attacks that might try to manipulate them. Due to these unique characteristics, and also in line with Bitcoin's recent success, there has been growing interest in applying blockchain technology to various domains, such as digital rights management [2][3][4], health care [5][6][7][8], Internet of things [9][10][11][12][13] and e-commerce [14,15]. In particular, applying blockchain's immutability to online payment systems can make it difficult for malicious entities to manipulate transaction history such as the amounts or ratings, which will result in better reliability, security, and trustworthiness of the systems.…”

A Model for Deriving Trust and Reputation on Blockchain-Based e-Payment System

E-commerce has become a crucial part of our life allowing us to buy products, request services, and transfer money easily with a press of a button. As such, establishing immutable trust and reputation of entities that are resilient to manipulation by the malicious are critical in today's online systems. In this work, we propose a model for calculating trust and reputation using the values stored on blockchain ledger. The model is applied to blockchain-based online payment systems which have a characteristic of immutability by preventing data manipulation. The model normalizes user evaluations based on each user's personal evaluation criteria that changes over time.In addition, the model derives reputation of, and trust between, users by applying psychological factors. We evaluate our model using not only simulated transaction data but also on real Bitcoin transaction-based dataset to show that our model is able to derive stable values from immutable transactions on blockchain-based online payment systems. Our model has been built into a live commercial blockchain service platform, and new application developments are underway.

“…K-anonymity protection ensures that information for each user contained in transactions cannot be distinguished from at least k − 1 users whose information also appears in transactions. In order to maintain existing smart devices and connect them to the blockchain network some authors [ 34 ] propose Blockchain Connected Gateways (BC Gateways) to protect users from providing personal data to IoT devices without user consent. In addition, the gateways store user privacy preferences on IoT devices in the blockchain network.…”

Resource consumption in residential areas requires novel contributions in the field of consumer information management and collaborative mechanisms for the exchange of resources, in order to optimize the overall consumption of the community. We propose an authorization system to facilitate access to consumer information and resource trading, based on blockchain technology. Our proposal is oriented to the Smart communities, an evolution of Community Energy Management Systems, in which communities are involved in the monitoring and coordination of resource consumption. The proposed environment allows a more reliable management of monitoring and authorization functions, with secure data access and storage and delegation of controller functions among householders. We provide the definition of virtual assets for energy and water resource sharing as an auction, which encourages the optimization of global consumption and saves resources. The proposed solution is implemented and validated in application scenarios that demonstrate the suitability of the defined consensus mechanism, trustworthiness in the level of provided security for resource monitoring and delegation and reduction on resource consumption by the resource trading contribution.
