Aspects of personal information valuation in web browsing and mobile communication

Laburpena

Dado el creciente volumen de datos que implica la interacción con la tecnología, es necesario que los usuarios entiendan y evalúen la importancia de diferentes tipos de información personal, con el fin de hacer mejor uso de ella. El objetivo de esta tesis es entender cómo los usuarios de las web y de telefonía móvil asignan valor a su información personal en dos relevantes contextos: la navegación web y la comunicación móvil. En esta tesis describimos dos estudios. En el primero se utiliza un Método de Muestreo de Experiencias refinado para obtener la valoración económica de la Información Personal Identificable (PII) de usuarios web. Observamos los valores de diferentes tipos de PII de manera comparativa, y reflexionamos sobre cómo estos valores se relacionan las preocupaciones de los usuarios sobre su privacidad y la monetización de su PII. El segundo estudio se enfoca en la anotación de llamadas telefónicas móviles, un proceso que involucra la selección de información que el usuario considera ser la más importante dentro de una llamada. Encontramos los factores que principalmente influencian la necesidad del llamante de tomar notas. También observamos cómo los comportamientos y necesidades de anotación cambian a través del tiempo. Finalmente, evaluamos diferentes técnicas de anotación, incluyendo anotaciones hechas por observadores independientes del contexto. Nuestros hallazgos incluyen ideas importantes para el desarrollo de herramientas automáticas de anotación, y además sugieren que existe potencial en el uso de crowdsourcing para encontrar información notable en llamadas telefónicas móviles.
