Abstract

Electronic Health Records (EHRs) are entirely controlled by hospitals instead of patients, which complicates seeking medical advices from different hospitals. Patients face a critical need to focus on the details of their own healthcare and restore management of their own medical data. The rapid development of blockchain technology promotes population healthcare, including medical records as well as patient-related data. This technology provides patients with comprehensive, immutable records, and access to EHRs free from service providers and treatment websites. In this paper, to guarantee the validity of EHRs encapsulated in blockchain, we present an attribute-based signature scheme with multiple authorities, in which a patient endorses a message according to the attribute while disclosing no information other than the evidence that he has attested to it. Furthermore, there are multiple authorities without a trusted single or central one to generate and distribute public/private keys of the patient, which avoids the escrow problem and conforms to the mode of distributed data storage in the blockchain. By sharing the secret pseudorandom function seeds among authorities, this protocol resists collusion attack out of N from N -1 corrupted authorities. Under the assumption of the computational bilinear Diffie-Hellman, we also formally demonstrate that, in terms of the unforgeability and perfect privacy of the attribute-signer, this attribute-based signature scheme is secure in the random oracle model. The comparison shows the efficiency and properties between the proposed method and methods proposed in other studies.

  • In the reviewed literature, relatively less attention has been paid to the prevention of external attacks, such as attacks on sensor data, escrow, and collusion attacks.

    “However, relatively less attention has been paid to the prevention of external attacks, such as attacks on sensor data (Brogan et al., 2018), escrow, and collusion attacks (Guo et al., 2018).”

  • Extant research indicates costs including linear increase in protocol costs based on entity characteristics, increased operational overhead and access latency, and transaction/execution costs based on string length and size.

    “Additionally, other costs indicated as constraints and limitations in the extant research include the linear increase in protocol costs contingent upon the characteristics and attributes of the involved entities, such as patients (Guo et al., 2018), increased operational overhead (for the patient) and access latency (for the requester) (Shen et al., 2019), and the transaction and execution costs”

  • There is a distinct lack of studies adopting a strategic perspective in organizational implementation of blockchain focusing on external attack prevention, value creation, or governance.

    “Third, there is a distinct lack of studies that adopt a strategic perspective in the implementation of blockchain in an organization focusing on aspects such as prevention of external attacks (Guo et al., 2018;Fan et al., 2018), value creation or governance (Risius & Spohrer, 2017).”

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.
