The multiple benefits of the Big Data new paradigm have being used in the novel nutrition-based vegetable production and distribution system in order to generate a healthy food recommendation to the end user, and to obtain different analytics results that could improve the system's efficiency. As next step in this study, the new paradigm Internet of Things (IoT) is included in the Big Data approach of the system to use its benefits, particularly automation and tracking technologies, to add much more data to the system to be processed in order to deliver to the user a much richer experience. In this regard, the IoT paradigm is bridging the real world with its virtual image, where devices located in different areas could exchange information each other without any type of supervision or control. But, spite of all the benefits that IoT could bring to society, the security of the information as well as privacy must be strongly enforced and managed in this new environment with unique characteristics. In our project we make a particular approach and security assessment of the use of IoT to provide automatic data to the system.
