Personal health record is sustained in the centralize server to preserve patient’s personal and diagnosis data. Personal health record (PHR) is a future patient-centric model of health data commutation, which is frequently outsourced to be stored at a third party, specified as cloud suppliers. However, there have been broad secrecy concerns as personal health information could be open to those third party servers and to unauthorized parties. The security systems are applied to protect personal information from public access. To secure the patients’ control over access to their own PHRs, it is a promising technique to encode the PHRs before outsourcing. In this paper we are giving some methods review for the security of the information from the external attacks.
