“…• In [23] the authors propose a blockchain-based system for securely storing electronic health records (EHRs) to address privacy and security concerns. EHRs are widely used in health institutions for access to accurate information, but they can be hacked, limiting patient access.…”

“…Four of these six works used zk-SNARK as the protocol while two used Bulletproofs. However, the performance analysis in [23] is not usable in our comparison since it analyses the performance of deploying smart contracts instead of the zero-knowledge proofs. Similarly, [28] only performed an analysis on the response times of the M1, 16GB RAM [40] unspecified "common computer" [41] Xeon Silver 4210, 16GB RAM [42] i7-9750H, 8GB RAM Other [75] i7-6700k (single thread), ?…”

“…Another avenue for future research, as proposed by [23], [36], and [47], involves exploring the applicability of the proposed solution in different domains or for alternative applications. These authors advocated for such investigations, believing that a solution employing zero-knowledge proofs could offer significant privacy benefits, potentially extending its usefulness beyond the specific subject explored in their respective works.…”

This systematic literature review scrutinizes the implementation and analysis of zk-SNARK, zk-STARK, and Bulletproof non-interactive zero-knowledge proof (NIZKP) protocols in privacy-preserving applications across diverse sectors. Examining 43 research works published from 2015 to April 2023, we categorized findings into financial, medical, business, general, and other domains. Our analysis highlights significant variations in real-world performance across implementations utilizing NIZKP protocols. However, divergent methodologies in security analyses hindered conclusive comparisons. Addressing research gaps, our future endeavors aim to establish a real-world benchmark for these protocols.

“…Zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is a cryptographic technique used in blockchain to provide privacy and confidentiality in transactions [56]. Utilizing zk-SNARKs in a blockchain-powered DCMS can guarantee the confidentiality of sensitive patient (DSs) sensitive data while permitting researchers (DRs) to access the necessary patient data for their research tasks.…”

“…Utilizing zk-SNARKs in a blockchain-powered DCMS can guarantee the confidentiality of sensitive patient (DSs) sensitive data while permitting researchers (DRs) to access the necessary patient data for their research tasks. According to Anusuya et al [56], zk-SNARKs enable the creation of a proof of knowledge that verifies the validity of transmitted data without exposing the actual data. This technology can securely transmit sensitive patient data over a blockchain network while remaining private.…”

Dynamic consent management allows a data subject to dynamically govern her consent to access her data. Clearly, security and privacy guarantees are vital for the adoption of dynamic consent management systems. In particular, specific data protection guarantees can be required to comply with rules and laws (e.g., the General Data Protection Regulation (GDPR)). Since the primary instantiation of the dynamic consent management systems in the existing literature is towards developing sustainable e-healthcare services, in this paper, we study data protection issues in dynamic consent management systems, identifying crucial security and privacy properties and discussing severe limitations of systems described in the state of the art. We have presented the precise definitions of security and privacy properties that are essential to confirm the robustness of the dynamic consent management systems against diverse adversaries. Finally, under those precise formal definitions of security and privacy, we have proposed the implications of state-of-the-art tools and technologies such as differential privacy, blockchain technologies, zero-knowledge proofs, and cryptographic procedures that can be used to build dynamic consent management systems that are secure and private by design.
