Prueba audiovisual, valoración de la prueba, deepfakes, autenticidad, inteligencia artificialResumen
Contextualización: Los avances recientes de la inteligencia artificial generativa han introducido nuevos desafíos al sistema de justicia penal, particularmente en el ámbito de la prueba digital. Entre las aplicaciones más problemáticas destacan los deepfakes, susceptibles de inducir a error en cuanto a su autenticidad, especialmente en contextos de mayor fragilidad probatoria, como los delitos de violencia doméstica.
Objetivos: El presente estudio tiene como objetivo general comprender las percepciones, experiencias y prácticas de los magistrados en relación con la admisibilidad y valoración de la prueba digital, con especial enfoque en los medios de prueba audiovisual y en los riesgos asociados a su eventual manipulación por tecnologías de inteligencia artificial generativa.
Método: Se adoptó un enfoque cualitativo, recurriendo a la realización de entrevistas semiestructuradas a ocho magistrados con experiencia profesional en procesos de violencia doméstica
Resultados: Se observaron limitaciones en la detección de elementos audiovisuales generados o manipulados por inteligencia artificial. La autenticidad de este tipo de elementos (deepfakes) ha granjeado más credibilidad que los elementos auténticos. De todos modos, aunque la prueba audiovisual se considera relevante, el testimonio de la víctima sigue considerándose la «prueba reina».
