Abstract
Personal health records (PHRs) contain sensitive health information that needs to be protected from unauthorized access. At the same time, patients may need to share their PHRs with healthcare providers or researchers to receive appropriate care or participate in medical studies. Attribute-based proxy re-encryption with keyword search (ABPRE-KS) is a what cryptographic technique that enables secure and controlled sharing of encrypted PHR data while preserving privacy and confidentiality of sensitive patient information. ABPRE-KS works by encryption of the PHR data using a key derived from the patient's attributes and allowing the patient to delegate access to the data to third parties using a proxy re-encryption scheme. To enable keyword search on the encrypted PHR data, an additional searchable encryption scheme can be used. ABPRE-KS provides a powerful tool for securely sharing and searching PHR and it can be used to facilitate better healthcare outcomes and medical research while protecting patient privacy.
