A Patient Privacy Protection Scheme for Medical Information System

摘要: In medical information systems, there are a lot of confidential about patient privacy. It is therefore an important problem how to prevent patient's personal privacy from being disclosed. Although traditional security protection strategies (such as identity authentication and authorization access control) can well ensure data integrity, they cannot system's internal staff administrators) accessing disclosing information. this paper, we present effective scheme protect patients' for system. the scheme, before stored in database server system would be encrypted using encryption algorithms, so that even if disclosed also difficult decrypted understood. However, execute various kinds query operations over efficiently, augment with additional index, process much possible at side, without need decrypt data. Thus, mainly explore index constructed, operation translated into new corresponding it executed side immediately. Finally, both theoretical analysis experimental evaluation validate practicality effectiveness our proposed scheme.
