Decentralizing Privacy: Using Blockchain to Protect Personal Data

Abstract

The recent increase in reported incidents of surveillance and security breaches compromising users' privacy call into question the current model, in which third-parties collect and control massive amounts of personal data. Bit coin has demonstrated in the financial space that trusted, auditable computing is possible using a decentralized network of peers accompanied by a public ledger. In this paper, we describe a decentralized personal data management system that ensures users own and control their data. We implement a protocol that turns a block chain into an automated access-control manager that does not require trust in a third party. Unlike Bit coin, transactions in our system are not strictly financial -- they are used to carry instructions, such as storing, querying and sharing data. Finally, we discuss possible future extensions to block chains that could harness them into a well-rounded solution for trusted computing problems in society.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Only the work proposed by [146] was intended to deal with privacy aspects based on the use of blockchain in smart cities.

    “Based on it, only the work proposed by [146] was intended to deal with privacy aspects based on the use of blockchain.”

    From Privacy-Preserving Solutions for Blockchain: Review and Challenges (2019) · cites this paper as [146]

    The Related Work section describes the paper's contribution as a blockchain-based personal data platform focused on privacy, supporting the identification of this work as addressing blockchain privacy. But Section II specifies a focus on mobile platforms, not smart cities, and the paper does not establish that it was the only work addressing blockchain privacy. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
