A Blockchain Platform for User Data Sharing Ensuring User Control and Incentives

Abstract : In the digital revolution, even secure communication between individuals, services and devices through centralized digital entities presents considerable risks.
Service providers collect and store information that is used for data mining, profiling and exploitation without users' knowledge or consent. Having service providers continue to offer their centric solutions is inefficient in terms of duplication, has serious security lacunae and is cumbersome to the users. The Self-sovereign Identity SSI concept, which includes the individual's consolidated digital identity and verified attributes, enables the users of data to exert their ownership and gain insights from their data's usage.
The authentication and verification of digital identity is essential to achieve the privacy and security of distributed digital identities. However, the current literature still lacks the comprehensive study on components of identity management as well as user privacy and data protection mechanisms in identity management architecture.
In this paper, we provide a coherent view of the central concepts of SSI, including the components of identity proofing and authentication solutions for different SSI solutions. Firstly, we discussed an overview of Identity management approaches, introducing an architecture overview as well as the relevant actors in such a system and blockchain technology as solution for distributed user-centric identity. Then we analyzed the authentication and verification mechanisms in the context of digital identity.
Finally, we discuss the existing solutions and point out the research gaps and elaborate challenges and trade-offs towards building a complete identity management system IdMs. Keywords : Identity proofing Authentication mechanism Self-sovereign identity Blockchain Claim verification.

E.P.A. Chief Vows to ‘Do Better’ to Protect Poor Communities
Blockchains have sparked great enthusiasm from the data science community who believes this technology will be THE solution to data authenticity, data privacy protection, data quality guarantee, smooth data access and real time analysis [1], [2]. Data being considered as the new digital oil, data science and blockchain seem to be the perfect match [3]. So, blockchain provides security and reliability of the manipulated data. But does it sound too good to be true?

Amid the growth in web3, NFTs, DeFi and tokens, institutional investors are also looking at how they can leverage another crypto structure called DAOs to build a new model for community action on the internet. The crypto collectives theoretically are designed around allowing groups to make decisions and operate in a structured capacity governed by smart contracts and blockchain transparency, but DAOs that are popping up recently seem to be indistinguishable from each other, with varying commitments to both decentralization and autonomy. While some camps have focused on how DAOs can be used as autonomous governance mechanisms for technologies like DeFi protocols, others are using them to make collective decisions for NFT project roadmaps, while some see the structure simply as a new way to add a crypto treasury to their Discord or Telegram group chat. The reality is that few people have a tight definition for what DAOs are, leaving room for new organizations to help the crypto-curious make sense of them and help would-be DAO founders make the most of the structure. Founders in the space say that the difficulty in pinning down a catch-all definition for what a "standard" DAO should look like only highlights how broad the opportunities are.

But that was by design, said Johnny Ryan , a senior fellow at the Irish Council for Civil Liberties, whose initial complaint about the IAB system kickstarted a wave of other complaints across Europe, including with the Belgian authorities. So we've crucified them on a pin rather than nailing in all the big nails. The decision is a big deal for Europe, Ryan said, but it could also have ripple effects across the Atlantic. This new decision, Ryan said, exposes that spam to be a violation of the law, not a fulfillment of it. It was a cynical attempt to undermine the law.
Estimating Harm in Invasion of Privacy and Data Breach Disputes
The researches on data security management and privacy protection technologies at home and abroad were analyzed and summarized aiming at current problems in blockchain security, such as unreasonable data management mode, unreliable data sharing scheme, smart contract vulnerabilities not easily fixed and incomplete privacy protection of multiple types of data. Various security problems and reasonable solutions in current blockchain systems were outlined from four aspects: data storage security, data privacy security, data access security and data sharing security. The challenges and future research directions of data security in blockchain were discussed.
3 Future Directions of Enterprise Security
Blockchain is a decentralized computation and information sharing platform that enables us to connect multiple authoritative domains where no one can trust each other in order to cooperate, collaborate and coordinate with each other in an intelligent decision-making process. Figure 1 shows that Blockchain is also a data structure which stores all the ordered set of block-organized transactions Zheng et al. The first block of the Blockchain is called genesis block. A block in a Blockchain can contain only a single transaction or more.
Abstract: Blockchain is a kind of distributed ledger technology with the characteristics of decentralization,security reliability,tamper-proof and programmable. The open and transparent feature of the blockchain system has seriously threatened the transaction privacy of users,and the corresponding privacy problem solution is designed for different application scenarios. Firstly,the basic working principle of block chain technology was introduced,and typical privacy issues was introduced in blockchain,such as transaction privacy and account privacy. Secondly,the existing typical blockchain privacy protection schemes were divided into three types:mixed-coin technology,cryptography technology and secure channel technology,and presents a comprehensive and comprehensive introduction to this three privacy protection schemes; Finally,the blockchain data privacy protection technology was analyzed,the application and development on IoT security were prospeted.

The research presented aims to investigate the relationship between privacy and anonymisation in blockchain technologies on different fields of application. The study is carried out through a systematic literature review in different databases, obtaining in a first phase of selection publications, of which 28 were selected for data extraction.
