Abstract: A number of research papers has been produced about reversible watermarking. Reversible watermarking is one of the important scheme of the watermarking schemes. Some security measures must be there to protect the records from unauthorized user and destruction of information. Basic idea of digital watermarking is to embed the data into the cover media to provide the security to data. The watermarking techniques satisfying these requirements called as Reversible watermarking. Ownership of the original media remains same but the best thing is original media is recovered from the watermarked media. This is the best and main feature of reversible watermarking to extract the original image as it is without any distortion. This feature is applicable in various areas such as medical as well as military images. If there is effect on the cover then it would changes the meaning of this data. The aim of this paper is to represent the purpose of reversible watermarking, some of the techniques related to reversible watermarking.

Abstract: In Indonesia, SMEs are the backbone of the Indonesian economy. Number of SMEs until 2011 to reach around 52 million. SMEs in Indonesia is very important for the economy because it accounts for 60% of GDP and 97% of the workforce holds. But access is limited to financial institutions only 25% or 13 million SMEs who have access to financial institutions. Indonesian government, SMEs, through the Department of Cooperatives and SMEs, in each province or regency / city. Although Small and Medium Enterprises (SMEs) is driving the nation's economy, but in reality many of the problems SMEs are still entangled. The main thing to note is the ability of SMEs to access a wider market. Because of the ability to change and adapt to a changing environment will determine the existence of small businesses in the nation's economy. In the end, the existence of small businesses that have high competitiveness will strengthen the nation's economy as a whole. Thus, in this study will use an appropriate technology tools that can provide assistance in introducing products through internet and increase sales in each SME This study uses a sample of students at the State University of Malang that can make a significant contribution in the small and medium businesses that are being initiated by students.

Abstract: Noise in images is the vital factor which degrades the quality of the images. Reducing noise from the satellite images, medical images etc., is a challenge for the researchers in digital image processing. Several approaches are there for noise reduction. Generally speckle noise is commonly found in Synthetic Aperture Radar (SAR) satellite images and medical images. This research paper put forward some of the filtering techniques for the removal of speckle noise from the satellite images, which enhances the quality of the images. Although many filters are available for speckle reduction, some filters are best suited for SAR images are used for which the statistical parameters are calculated for the output images obtained from all the filters. The statistical measures SNR, PSNR, RMSE and CoC are compared. The output images corresponding to the best statistical values are displayed along with the filters name and corresponding values of the statistical measures.
