Auditable Message Token for Secure Web Service Communication

The patent introduces a token provider as an intermediary component that generates and manages security tokens. This mediator sits between the source service and target service, issuing auditable message tokens that encapsulate security context and transmission history. The token provider centralizes security logic, allowing services to communicate securely without each service implementing complex security validation mechanisms themselves.

The patent embeds multiple layers of security information within nested token structures. The auditable message token contains nested elements including transmission history, security context, validation results, and attack detection records. This nested structure allows complex security functionality to be packaged within a single token object that can be passed through the communication chain without expanding the message structure externally.

The token provider performs security validation and attack detection actions in advance before the message reaches the target service. By pre-validating the token and detecting potential attacks during token generation and initial processing, the system avoids repeated validation cycles that would slow down message transmission. The auditable token carries forward security context so subsequent services can rely on pre-established validation results.

The patent implements feedback mechanisms where the token provider receives confirmation data from target services about message receipt and processing. This feedback loop allows the system to track which security checks have been performed and adjust validation intensity accordingly. Services can provide feedback about successful validation to avoid redundant checking, optimizing the balance between security thoroughness and transmission speed.
