PHR(Personal health Record) is a model which is using for exchange the health information of patient. Generally PHR system is operate by the third party for storage purpose like cloud storage purpose. Though there are a lot of concerns over privacy like PHI that can be show to servers & unauthorized users of the third party. Before outsource the PHR data, PHR data encryption is very important for the security reasons. In this paper, we are working over enhancing the security of PHR by implementation of DWT that is based over Steganography. Steganography is that process in which information can be hided in a picture. Steganography has the ability of inserting more information into one image. PHR data will be hided in one image by Steganography. In the Steganography encryption & decryption process will be executed by DWT. In this paper, we are working for hiding the PHR data into a single image for the security reasons. For hiding the PHR data into an image, Wavelet based Steganography is proposed in this paper. In the results, Elapsed time and Error rate get reduce up to 80-90%.
