Blockchain-Enhanced Privacy Protection in Social Network Research and Applications

Abstract

While social networks offer users unprecedented convenience and connectivity, they inadvertently risk exposing sensitive user data. To address the juxtaposition of utility and vulnerability, this paper delves into the potential of blockchain technology as a tool for enhancing privacy protection within social networks. By first critiquing the limitations of current protective measures, it becomes clear where traditional methods fall short in counteracting common avenues of privacy breaches. This paves the way for the integration of blockchain technology into the privacy infrastructure of social networks. The paper elucidates the core cryptographic principles underpinning blockchain and, by drawing from real-world applications such as ShoCard, underscores the advantages that this nascent technology brings to the fore. Despite the evident merits, challenges remain, especially as the technology becomes a potential target for advanced cyber-attacks. The incorporation of elements like smart contracts, digital signatures, and decentralized storage manifests blockchain's promise in building a robust digital fortress, safeguarding user privacy. However, as the technology is still in its evolutionary phase, ongoing research must address vulnerabilities and ensure a holistic defense against potential threats.
