A Medical Information Monitoring System Based CP-ABTD for Safe Medical Information Sharing in Fog Computing Environment

Recently, the technology that allows to remotely receive medical service through a smart medical information service has been presented. However, medical information dealt with in such service can infringe people's privacy. Therefore, it is necessary to introduce information security technology including encryption. Only an authorized person who can access to service user's data should be allowed to see the information. To achieve the goal, it is essential to delegate access privilege or even remove the access privilege under a certain circumstance. Such issues can be improved with attribute based encryption. This paper applies user's attribute based encryption, which allows to delegate or revoke an access right to a medical information monitoring system. In addition, it creates a scenario of a medical information monitoring system and propose a relevant system structure using user's attribute, based encryption.
