This paper proposes a new technique based on reversible watermarking to improve information embedding capacity and security level in medical images. This technique uses two methods namely Image compression and image partitioning techniques. Original image is converted into R-S Vector interms of ones and zeros and it is compressed to provide space for embedding more information. Hash value is calculated from original image to analyze security level. Image partitioning technique divides the image into two parts then secret information is embedded into LSB bits. This image compression and partitioning technique improves the information embedding capacity level and hash output confirms the image integrity level.
