Farmers are confused to take correct decision regarding selection of fertilizer, pesticides, etc., time to do particular farming actions and the price for their products that they produce and sell. To overcome all problems, we proposed an android-based app, which addresses the issues of farmers, benefits them with additional guidance regarding soil type, fertilizers, pesticide, irrigation requirements etc. Our proposed system “Secure light-weight Android application for Farmer based on Rating and reviews” (SAFR) provides security for payment as well as data encryption (AES algorithm) using different security based algorithms. SAFR provides rating and review using the Collaborative Filtering Recommendation Algorithm (CFRA).

INTRODUCTION The agriculture sector has a big contribution in the economic development of India. A large population in India depends on agriculture to fulfill their livelihood. Agriculture combines the cultivation of crops, breeding of animals for food, fiber, biofuel, medicines and other products used to sustain and enhance human life. Farming is the key development in the ascent of human culture, which produces food surpluses that nurtures the growth of culture. In India, most of the population is dependent on farming. However, updating the technology needs reviewing and revitalizing the mechanism. Agriculture may see major changes in upcoming years due to enhancement in technologies. Agriculture is believed to be the mainstay of Indian economy. Now-a-days farmers are having huge economic losses due to several causes. To overcome the problem of economic loss, we propose the System-Secure Android application for Farmers based on Ratings and reviews (SAFR). Farmers are confused to take right decision regarding selection of fertilizers, pesticides and time to do particular farming actions, the price for their products that they produce and sell. SAFR serves as a platform for movement of agricultural products from the farms directly to the consumers or retailers. SAFR is a mobile application, which provides privilege for both farmers and consumers/retailers to buy and sell the required products without the involvement of an intermediary at the product’s fair profitable price. Today everyone, including the farmers and countryside people, utilizes mobile devices frequently. A mobile device is preferred over other devices for presenting SAFR as mobile devices can include a number of applications, which any user can access independent of other applications, and cost is comparatively low. Information & Communication Technologies (ICT) observed that mobile plays vital role in everyday life of farmers [4]. The application management interface of mobile devices includes a menu part and a display part. The menu part of application management interface includes multiple tabs, each tab providing access to particular feature related to particular tab. The display part of application management interface includes one or more than one application objects, each application object presenting information about respective application. The objective of modern farming technique using SAFR is to enhance transparency in the agriculture commodity market place by providing market price information, facilitating collective buying of inputs and selling of products. Farmers rely on weather forecasts to decide what work to do today and tomorrow. We introduce and provide detailed information on an Android based multilingual app “Secure Android application for Farmers based on Ratings and reviews (SAFR)”, which targets to provide solution /suggestion to the farmer’s problems, facilities, benefits them with additional guidance in their area of interests like soil type, fertilizers, irrigation requirements etc. Security is the main objective of SAFR. SAFR provides secure payment gateways by using standard algorithm and data security by encrypting the private data using AES algorithm. Collaborative Filtering Recommendation Algorithm is used for rating and review of products. Rating and reviews over products can help the buyers to choose the most convenient product for themselves. II. MOTIVATION Farming is the mainstay of our Indian economy, but farmers are the one who face huge economic losses. The responsibility of today’s generation is to maintain farming as the backbone of our nation’s economy for a lot more generations to come. Farmers suffer a lot when drastic change in climate occurs due to rising global temperature. Crop failure due to unsuitable weather conditions is a major concern, which forces farmer to end their lives. Modern technologies are helpful to many people and organizations, so SAFR can be useful for helping the farmers as well. Our proposed system SAFR solves the problems of farmers at one click and provides secure transactions. III. RELATED WORK In a recent survey by Sowmyaa Guptaa and Gaurav Trivedi [4], the proposed system, which is an android based application e- krishakMitra, is intended to address the farmer issues and find an efficient solution for their problems that can help them with smooth farming taking into consideration the present weather conditions. e-krishakMitra is a cloud-based application that integrates
