With the rapid advance in digital network, digital libraries, and particularly WWW (World Wide Web) services, we can retrieve many kinds of information anytime. Thus,security has become one of the most significant ptoblems for distributing new information.It is necessary to protect this information while communicated over insecure channels.Thus a need for developing technology that will help to provide security as well as authenticity.Steganography is the idea of hiding private or sensitive data or information within something that appears to be nothing out of the normal. Steganography and cryptography are similar in the way that they both are used to protect important information. Nowadays the term "Information Hiding" relates to both watermarking and steganography. So we proposed combined strategy of cryptography, steganography and digital watermarking to hide secure image with watermark logo inside cover image. For this purpose we use DCT, DWT, SVD and RSA approach. Using DCT, encrypted watermark logo (encryption perform using RSA) is hide inside Secure image, results in Stego image. This Stego image is hiding inside cover image using DWT and SVD. Our approach can be used to transmit secure information like copyright information of company, movie with their respective image, finger-print or thumb impression of particular person. This method can be used for security purpose. Thus would be beneficial to nation for over all security.

Subacute combined degeneration (SCD) from vitamin B12 deficiency and spinal stenosis from degenerative changes may present similarly with weakness, sensory disturbances, and ataxia but require different treatments. This case report describes a 74-year-old male with suspected SCD who was discharged to an inpatient rehabilitation facility (IRF), did not improve with B12 supplementation, and later developed signs of myelopathy and diffuse joint pain. He ultimately was found to have severe cervical stenosis and pseudogout that were treated with a laminectomy and colchicine, respectively. Following surgical intervention, he returned to the IRF, where he had considerable functional improvement and was safely discharged home. This report shows the importance of recognizing the two conditions, their overlap, and the contrast between Occam's razor and Hickam's dictum.
