“…In 2008, Satoshi Nakamoto proposed the concept of blockchain [13] , [31] , which is a distributed database managed autonomously through peer-to-peer Network and distributed servers. In blockchain, all data are decentralized stored in all nodes involved in recording data and maintained by all participants rather than stored centrally in the central node, which is a secure, unforgeable, and trustworthy distributed database.…”

“…Information security blockchains are generally secure owing to asymmetric cryptography. However, as more attacks are developed, researchers have become interested in the ability of blocks to withstand attacks [43,44,46,52,55,56,61,71,72,77], such as inference attacks, poisoning attacks, DoS Hulk attacks, DDoS attacks, Portscan attacks, replay attacks, Sybil attacks, man-in-the-middle attacks, identity theft attacks, traffic analysis attacks, masquerading attacks, session key disclosure attacks, public ledger attacks, denial of service attacks, strongand weak-collisions attacks, compromised server attacks, insider attacks, stolen smartcard attacks, offline password guessing attacks, impersonation attacks, message modification attacks, fake/bogus message attacks, reply attacks, Eclipse attacks, collusion attacks, quantum computing attacks, and stolen authenticator attacks; 2. Anonymity refers to the exchange of addresses and information realized by users in a blockchain system to interact without revealing their true identities.…”

Faced with the impact of the coronavirus disease (COVID-19) pandemic, governments must protect the well-being of the population. Aside from considerations, such as keeping the virus from spreading and treating patients, the government should also be concerned about the mental health of its citizens during the epidemic. This study aimed to help users who develop depression due to COVID-19 on social media, reduce the cost of counselling, and reduce the need for users to visit the hospital for counselling. This study investigated the opportunities for blockchain technology to provide psychological help to social media users suffering from depression caused by the pandemic. Blockchain-based technology has been used to develop a new model that enables a user autonomy system to allow users to control their own data fully. The model utilizes a delegated proof of stake consensus blockchain to manage depression data to enable low cost and information security while discussing aspects related to trust, privacy, interoperability, and integration with other information communication technologies. The blockchain framework has been proven to provide secure and reliable information management that meets the user requirements for information autonomy. The framework can be combined with various other information technologies to extend its functionality further. Blockchain, privacy, user autonomy, depression, social media. INDEX TERMS

With the rapid development of Non-Fungible Token (NFT) market, various types of digital artwork are published via NFT in recent years for sale. In the current NFT system, owner's address of each NFT is stored in plaintext. This leads to a severe privacy problem: once a person's blockchain address is known, all his NFT assets are viewable, which may further cause problems related to the privacy of holding sensitive NFT or premeditated scams to high-value NFT owners. However, due to the limitation of Ethereum and smart contract, it is hard to prevent others from tracking the owner of NFT. Meanwhile, current state-of-the-art NFT research usually assumes the relation between blockchain address and owner's identity is unknown, thus creating the so-called anonymity. In this paper, based on the most popular NFT marketplace OpenSea's system, we propose a new exchange scheme to hides the address of NFT owner during trading. To achieve our goal, a proof of commitment scheme is exploited to bind the owner to an NFT while hiding the identity. Moreover, An anonymous payment method is designed to prevent attackers from tracing the Ether flow in NFT trading. Our scheme is proven to be secure against curious users and malicious active attackers. Implementation on testnet also shows that the increased gas cost is acceptable, meaning it is suitable for application.INDEX TERMS Non-Fungible Token, owner privacy, blockchain, security
