    Personal Data Broker Instead of Blockchain for Students’ Data Privacy Assurance
    (Springer, 2019-04-01) Amo, D.; Fonseca, D.; Alier, M.; García-Peñalvo, F. J.; Casañ, M. J.
    Data logs about learning activities are being recorded at a growing pace due to the adoption and evolution of educational technologies (Edtech). Data analytics has entered the field of education under the name of learning analytics. Data analytics can provide insights that can be used to enhance learning activities for educational stakeholders, as well as helping online learning applications providers to enhance their services. However, despite the goodwill in the use of Edtech, some service providers use it as a means to collect private data about the students for their own interests and benefits. This is showcased in recent cases seen in media of bad use of students’ personal information. This growth in cases is due to the recent tightening in data privacy regulations, especially in the EU. The students or their parents should be the owners of the information about them and their learning activities online. Thus they should have the right tools to control how their information is accessed and for what purposes. Currently, there is no technological solution to prevent leaks or the misuse of data about the students or their activity. It seems appropriate to try to solve it from an automation technology perspective. In this paper, we consider the use of Blockchain technologies as a possible basis for a solution to this problem. Our analysis indicates that the Blockchain is not a suitable solu-tion. Finally, we propose a cloud-based solution with a central personal point of management that we have called Personal Data Broker.

    Posibilidades del Blockchain en Educación
    (Ediciones Universidad de Salamanca, 2018-12-31) Bartolomé, A.; Lindín, C.
    Blockchain es una nueva tecnología que está irrumpiendo con fuerza en muchos campos, y también en el sistema educativo. Pero no se trata de una tecnología específica con la que se puede esperar mejorar una situación concreta: se trata más bien de una tecnología que permite registrar eventos de una forma totalmente innovadora. Y esto puede traducirse en cambios insospechados. Tras presentar qué es blockchain y algunos ejemplos de usos sociales, se analizan, en las aplicaciones actualmente en uso, los problemas a los que la tecnología pretende dar respuesta. Una revisión de las experiencias más destacadas, todas en una fase incipiente de desarrollo, nos lleva a algunas conclusiones críticas sobre su viabilidad.
