Embedding Patient Information In Medical Images Using LBP and LTP
Circuits and Systems: An International Journal (CSIJ), 1 (1): 39-48 (January 2014)
Abstract
In this paper a new efficient interleaving methodology in which patient textual information is embedded in medical images considering Magnetic Resonance Image, Ultrasonic image and CT images of that patient body. The main disadvantages in traditional techniques to Embed patient information in medical images is inability to withstand attacks and Bit Error Rate (BER) when maximum number of characters to be embedded are absent in proposed algorithm. The New robust Embedding Techniques, Local Binary Pattern (LBP) and Local Ternary Pattern (LTP) are used to embed the patient information in medical images. LBP Technique is mainly used to provide the security for the patient information. Along with the security high volume of patient information can be embedded inside the medical image using LTP technique. Statistical parameters such as Normalized Root Mean Square Error, PSNR (Peak Signal to Noise Ratio) are used to measure the reliability of the present technique. Experimental results strongly indicate that the present technique with zero BER (Bit Error Rate), higher PSNR (Peak Signal to Noise Ratio), and high volume of data embedding capacity achieved using LTP as compared with the other data embedding techniques. This technique is found to be robust and watermark information is recoverable without distortion.
