How to Improve Food Security and Farming Systems by Using Wireless Sensor Networks (WSN)

According to a survey approximate 925 million people do not have enough food to eat. So it is a challenge to secure food as well as produce enough to fulfil all needs. A person can live without other necessities but cannot live without food. The food security refers to the ability of food systems to ensure that everyone has enough food to live a healthy life.  A household is considered food-secure when its occupants do not live in hunger or fear of starvation. There are many reasons behind this, due to poor farming system, export restrictions, panic buying, increased farming for use in bio-fuels, global population growth, climate change, loss of agricultural land to residential and industrial development, and growing consumer demand in largest populated country such as China and India are claimed to have pushed up the price of grain. Some other factors which also cause food shortage, the agricultural productivity; soil health, water security, and food quality in storage and distribution are identified as the primary determinants of food security. So in this paper we have discussed how to secure food and enhance farming system by using Wireless Sensors Networks (WSN).

A Study of Image Fingerprinting by Using Visual Cryptography

As digital media has made our life more colourful because of its advantages like easier to access, copy and distribute. But as what we have seen, series of malice activities like copyright infringement, counterfeiting, piracy and information distortion make damages to both the producers and the users of digital products. So we really need some technology to protect the copyright, authenticity, integrity of the digital products and the intellectual property of the users. There are many techniques such as Digital watermarking and Visual Cryptography both have been widely used for protection of data either in text, video, sound or digital images form in modern network time. Digital watermarking is an evolving field that requires continuous effort to find for the best possible method in protecting multimedia content. But Visual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used. Both techniques addresses the growing concerns of theft and tampering of digital media through the use of advanced signal processing strategies to embed copyright and authentication information within media content in their respective manner. In this paper we have discussed image fingerprinting with the help of visual cryptography technique.
