Towards building weak links between persistent digital identity documents: MetaEngine and distance to make identity less visible

Abstract

Currently, metadata are being democratized and used for various purposes. We present a novel metadata-based mechanism to help making weak links between digital identity documents based on distance score that is generated by a distance function and performance. We identify two parameters of the distance function: elapsed time t and a random vector, which is defined by joint probability density for forgetting between two documents. The more the distance score is high the more the link established between parent and child document becomes weaker, therefore the child document becomes less visible. This would provide user more control over his identity and promote forgiveness in the digital age. We provided also an XRD implementation of the parent and child DigIdMeta documents. © 2011 Springer-Verlag.
