  • Entitlement access token
    Patent number: 10602094
    Abstract: A top-level service executes a procedure call to at least one dependent service to determine an entitlement result for a user device making a request of the top-level service. A processing device generates an entitlement token comprising the entitlement result, encrypts the entitlement token and sends the entitlement token to the user device. The user device can return the entitlement token when making additional requests of the top-level service to prevent the top-level service from having to make additional procedure calls to the at least one dependent service.
