Prafull Agarwal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11930116
    Abstract: A monitoring service monitors performance of an authentication application that authenticates a user or service and securely communicates a status of the authentication application to a service application providing a software service. The monitoring service generates a token using a private key. The token is stored in a secure datastore writable only by the monitoring service and is also provided to the service application. The service application validates a signature of the token using a public key and determines an authenticity of the token by comparing the received token to the stored token in the secure datastore. In doing so, there is a high degree of confidence that the token, or an associated encrypted message, originated from the monitoring service and properly identifies the status of the authentication application.

  • Patent number: 11568026
    Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for implementing asymmetric cryptography for digital rights licensing during system disruptions. In particular embodiments, the disclosed systems transmit, to a licensing device that issues digital licenses, a digital communication indicating a system outage of an identity server that verifies digital licenses of client devices. Based on the digital communication, the disclosed systems call a monitoring device using a licensing device identifier. In response to the call, one or more embodiments of the disclosed systems use the monitoring device to encrypt and transmit a verification token back to the licensing device. In certain implementations, the disclosed systems then verify the system outage by decrypting the encrypted verification token and validating a corresponding digital signature.
