Sustainability Design Applied to the Digital Signature of Documents

Abstract

Information and communication technologies can be an added value in order to provide integrated services to customers. With the technological advancements of the last decades, writing is increasingly done in electronic documents. Digital signatures are designed to ensure authentication, integrity, and non-repudiation of such documents. The methodology was based on the literature review of the field, as well as the description of the case study which emphasizes the added value of the developed application, since it addresses concerns of several dimensions of sustainability. The purpose of the chapter is to describe a case study in which an Android mobile application, SoftDigital, was developed for document flow management in a hospital environment, meeting the principles of sustainability design for the development of software systems. It is therefore considered that the main conclusions are to allow healthcare professionals and patients (or their legal representative) to integrate their digital signature into documents for approval of treatments electronically.
