Automated Deployment of Data Lake

A Data Lake is a central location that can store all your structured and unstructured data, no matter the source or format. Automated deployment for data lake solution is an automated reference implementation that deploys a highly available, cost-effective data lake architecture on the AWS Cloud along with a user-friendly console for searching and requesting datasets. The solution automatically configures the core AWS services necessary to easily tag, search, share, transform, analyse, and govern specific subsets of data across a company or with other external users. The solution deploys a console that users can access to search and browse available datasets for their business needs.

Privacy-Preserving RFID-Based Search System

The employment of mobile readers (or mobile phone collaborated with a Radio frequency identification (RFID) reader) opens a novel application for RFID technology. In particular, an RFID tag search system has been designed to find a particular tag in a group of tags using a mobile reader. Unfortunately, privacy infringement and availability issues in the search system have not been adequately addressed to date. In this paper, we propose a novel RFID tag search protocol that will enhance mobile reader user privacy while being able to operate under conditions of unstable connection to a central server. First, the proposed protocol preserves the privacy of mobile reader users. The privacy of the mobile reader user is at risk because the signal strength emitted from a mobile reader is much stronger than that from the tag, exposing the location of the mobile reader user and thus compromising the user’s privacy. Thus far, such privacy issues have been overlooked. The second issue is presented because of wireless connections that are either unreliable or too remote, causing a mobile reader to disconnect from the central server. The proposed protocol enables serverless RFID tag searches with passive tags, which obtain operating power from the mobile reader. In unstable environments, the protocol can successfully locate specific tags without any server.

Levantamento de Tecnologias para ONGs de Proteção Animal para apoio ao resgate de animais domésticos acoplados ao ciclo de vida de um sistema Web

This paper reports on the stages of identification of existing technologies that can be used to identify and rescue lost animals and to disseminate animals for adoption by NGOs of Animal Protection, Zoonoses Center and Protective Guards. In this article the developed phases of the Course Completion Work are presented. For this, an exploratory research was carried out initially, followed by a questionnaire seeking to identify which technologies are used to identify, locate, rescue and adopt domestic animals. The current technologies found were Microchip - RFID, Microchip - NFC, Collar with qrCode, Collar with Tag, Search application, Identification application, Social networks. In this way the research reports the main technologies used to date and is going to develop an application proposal to improve and expand the dissemination of pets that are lost or for adoption.
