Security for EHR Based on ECC with Reconstruction Method

Abstract

Electronic Health Record plays vital role in hospitals and healthcare organizations. security is one of the main issues in EHR . Electronic Health Record allows only the licensed people can access the records. EHR ensure high-quality care. EHR contain treatment histories of patients. Using basic algorithms like symmetric algorithms, public key cryptography, RSA algorithm the Electronic health care can be secured, but there may be a few drawbacks to obtain integrity and confidentiality .The proposed ECC (Elliptical Curve Cryptography) will provide high security in EHR and obtain confidentiality and integrity. The doctors diagnoses, treatment plans, radiology images, and laboratory a test results. Treatments and guidance from doctors to patients mostly through e-mails, also many parties store and run computation while keeping the sensitive health data private.so cipher attack may cause heavy damage from the patients side therefore data may be secure. In order to address this issue this paper presents a patient healthcare data management system using reconstruction outsourcing mechanism to attain privacy in HC.
