Computação na nuvem: autenticidade e acessibilidade ao longo do tempo

Abstract

From the evolution of the internet, the problem of guaranteeing the authenticity of digital documents in the cloud arises. With that, this work comes with the objective of elucidating some questions about this topic, seeking to analyze the services available for cloud computing and their respective security in relation to the authenticity and reliability of digital archival documents in the cloud. Based on this, the objectives of this work and its respective theoretical framework were defined, based on four main pillars: Cloud computing; Digital archival document; InterPARES Project and Digital Preservation. In view of these pillars, several texts on the subject were analyzed, obtained from the methodology applied in this work, which is considered applied, exploratory and bibliographical. However, the results obtained in this study were satisfactory, since the types of public, private, hybrid and community cloud and their respective services SaaS, PaaS, IaaS, DaaS, CaaS, EaaS, DBaaS, FaaS and PaaS were identified, as well as the characteristics of the digital archival document and the initiatives identified to guarantee the authenticity of documents in the cloud, which were the metadata, considered a mechanism to help in the preservation with authenticity. In addition, the OAIS reference model that also serves to assist in long-term digital preservation and the PaaST model that is presented as a result of the InterPARES project as an element to guarantee the trust of documents in the cloud, complementing the OAIS model.
