Abstract
Disclosed are various approaches for using Markov chains and hidden Markov Models to enhance API access controls for secure data. Various embodiments disclosed in this application introduce an access control application between the APIs and a data store that uses Markov chains or hidden Markov models to validate, check, or verify that the data request meets expected security guidelines. These embodiments can enhance security for all requests for data. Additionally, these embodiments can serve as an additional, automated security defense when a developer misconfigures or fails to include the appropriate validation logic within an API.
