US Patent 10904254 Transaction security systems and methods

Outbound traffic of a host application may be received from a host device having a host processor. The secure resource may be configured to provide a secure transaction based on the outbound network traffic. Using a second processor different than the host processor, it may be determined whether the host application is authorized to provide the outbound network traffic to the secure resource. The outbound network traffic may be allowed to be forwarded to the secure resource if the host application is authorized. The outbound network traffic may be disallowed to be forwarded to the secure resource if the host application is not authorized.
