The Covid-19 pandemic is spreading worldwide, the demand for controlling and screening fever is increasing very rapidly. Some traditional methods like using thermometers or medical checking cannot handle many people in crowded areas such as airports, train stations, or buildings. Some thermal imaging systems are used to control people’s ins and outs. These systems help many governments decrease and prevent viruses’ spread by screening human temperature based on skin radiation. Despite all of the advantages this technology has had, this system’s very high cost is one reason to prevent some organizations from applying it despite the high potential of image processing, artificial intelligence, and the Internet of Things. This paper will present a system combining a low-cost thermal camera and a standard RGB camera for screening fever combined with attendance checking. The experimental results show that this proposed system can be applied in many areas, from universities to buildings, with the minimum cost and acceptable performance.

Community Supported Agriculture (CSA) model is an efficient solution that not only solves the problem of the agricultural product’s origin but also provides a method to share the market risk between consumers and producers. In the CSA model, consumers order and pay for products in advance. Then, the producers will send packages of fresh products to consumers after a fixed period corresponding to the paid amount. However, the critical weakness of the CSA model is the lack of solutions for both sides to demonstrate the product’s quality, which makes consumers unsure about the condition of receiving products. In consequence, consumers become hesitant to order and pay money in advance. In this paper, we will propose a novel solution that allows consumers to track their products through agricultural diaries recorded by farmers every day. The key difference of the proposed solution is to leverage Blockchain technology advantages in authenticating and protecting the integrity of information. Such that, consumers could track all steps in the production process quickly and reliably. Meanwhile, producers can build and increase their enterprise branding by transferring product information transparently and responsibly.
