A Security Pattern for Key-Value NoSQL Database Authorization.

Numerous authorization models have been proposed for relational databases. On the other hand, several NoSQL databases used in Big Data applications use a new model appropriate to their requirements for structure, speed, and large amount of data. This model protects each individual cell in key-value databases by labeling them with authorization rights following a Role-Based Access Control model or similar. We present here a pattern to describe this model as it exists in several Big Data systems.
