A secure protocol for protecting the identity of providers when disclosing data for disease surveillance

Abstract: BackgroundProviders have been reluctant to disclose patient data for public-health purposes. Even if patient privacy is ensured, the desire to protect provider confidentiality has been an important driver of this reluctance.MethodsSix requirements for a surveillance protocol were defined that satisfy the confidentiality needs of providers and ensure utility to public health. The authors developed a secure multi-party computation protocol using the Paillier cryptosystem to allow the disclosure of stratified cas… Show more

“…However, the resulting integrated de-identified dataset does not satisfy a standard privacy model (e.g., k -anonymous) and suffers a significant loss of utility [85,86]. Even when individuals' privacy is protected, the de-identified dataset of a healthcare provider might reveal its sensitive business information [29].…”

“…Other examples of deploying MPC for social good include tax fraud detection [6] and disease surveillance [7]. Additionally, because MPC decouples computing and networking resources from data, users can leverage the benefits of large data centers without ceding control over their sensitive data.…”
