Abstract: The present disclosure provides systems, methods, and products for providing a tokenization service and a complementary API. The tokenization service may provide format-preserving tokens. The tokenization service may associate different tokens generated by different users from the same data, so that users can retrieve and use associated tokens for collaboration and access to each other's data, information, etc. The tokenization service may restrict the creation of an association between, and access to, users' tokens based on a requirement for a relationships between users according to a social graph model.
