Query: Trust Me If You Can: Trusted Transformation Between (JSON) Schemas to
  Support Global Authentication of Education Credentials   Recruiters and institutions around the world struggle with the verification
of diplomas issued in a diverse and global education setting. Firstly, it is a
nontrivial problem to identify bogus institutions selling education
credentials. While institutions are often accredited by qualified authorities
on a regional level, there is no global authority fulfilling this task.
Secondly, many different data schemas are used to encode education credentials,
which represents a considerable challenge to automated processing.
Consequently, significant manual effort is required to verify credentials.
  In this paper, we tackle these challenges by introducing a decentralized and
open system to automatically verify the legitimacy of issuers and interpret
credentials in unknown schemas. We do so by enabling participants to publish
transformation information, which enables verifiers to transform credentials
into their preferred schema. Due to the lack of a global root of trust, we
utilize a distributed ledger to build a decentralized web of trust, which
verifiers can query to gather information on the trustworthiness of issuing
institutions and to establish trust in transformation information. Going beyond
diploma fraud, our system can be generalized to tackle the generalized problem
for other domains lacking a root of trust and agreements on data schemas.
