Teaching self-sovereign identity

Abstract

Para los proveedores de servicios, la identificación segura y confiable de los usuarios es fundamental para prestar sus servicios. Desde la perspectiva del usuario, los identificadores tradicionales actualmente son proporcionados por entidades centralizadas que tienen la capacidad de controlar, no solo la creación del identificador, sino también la retirada. Además, en la mayoría de los casos se proporciona más información personal de la que se necesita demostrar. Una Auto-Identidad Soberana basada en blockchain proporciona un método de identificación seguro y fiable para los proveedores de servicios, le da al usuario el autocontrol del identificador y permite una forma de proporcionar sólo la información esencial que se necesita para obtener el servicio. Este trabajo tiene como objetivo realizar dos documentos prácticos, siendo el primero una práctica introductoria para iniciarse en este tema y el segundo que consiste en desarrollar un sistema de inicio de sesión de Auto-Identidad Soberana simple para servicios web ofrecidos a estudiantes universitarios.

Per als proveïdors de serveis, la identificació segura i fiable dels usuaris és fonamental per prestar els seus serveis. Des de la perspectiva de l'usuari, els identificadors tradicionals són proporcionats actualment per entitats centralitzades que tenen la capacitat de controlar, no només la creació de l'identificador, sinó també la retirada. A més, en la majoria dels casos es proporciona més informació personal de la que cal demostrar. Una identitat autosobirana basada en blockchain proporciona un mètode d'identificació segur i fiable per als proveïdors de serveis, dóna a l'usuari l'autocontrol de l'identificador i permet una manera de proporcionar només la informació essencial que es necessita per obtenir el servei. Aquest treball té com a objectiu fer dos documents pràctics, sent el primer una pràctica introductòria per iniciar-se en aquest tema i el segon que consisteix a desenvolupar un sistema d'inici de sessió d'identitat autosobirana simple per a serveis web oferts a estudiants universitaris.

For service providers, secure and reliable identification of users is essential to provide its services. From a user perspective, traditional identifiers are currently solved by centralized entities who have the capacity to control not only the creation of the identifier, but also the withdrawal. Moreover, in most cases more personal information is being provided than needs to be demonstrated. A blockchain-based Self-Sovereign Identity (SSI) provides a secure and reliable identification method for service providers, gives the user self-control of the identifier, and enables a way to provide just the essential information that is needed to get the service. This paper aims to make two practical documents; the first one being an introductory practice to get started with this topic and the second one that consists of developing a simple SSI login system for web services offered to university students.
