Abstract: With the rapid advancement of blockchain technology in recent years, its application in scenarios requiring confidentiality, such as the health sector, has become encouraged and extensively discussed. This paper presents an architecture for protecting the privacy of stored health-related data. This paper presents an architecture to ensure the privacy of health-related data, which are stored and shared within a blockchain network in a decentralized manner through encryption with the RSA, ECC, and AES algorithms. To determine the impact of cryptography on the proposed architecture in terms of computational effort, memory utilization, and execution time, evaluation tests were conducted. The results primarily impact the execution time and the increase in computational effort for transmitting data to the blockchain. This is justifiable in light of the privacy and security offered by the architecture and encryption.
