Abstract
A signature graph method is proposed to authenticate shared high-entropy data using a graph that can be easily identified by human eyes (or by computer image recognition algorithms). An example method for authenticating a shared data element comprises receiving a data element to be shared; transforming the data element to be shared into signature graph data, using at least one collision-resistant one-way mapping function; and rendering a human-perceptible representation of the signature graph data, such as an audible and/or visual representation, for perception by a human user. In some embodiments, transforming the data element comprises applying a cryptographic hash function to the data element, to obtain a first hash output, and applying a cryptographic hash function to the first hash output, to obtain the signature graph data.
