Cryptographic integrity verification and adaptive artificial intelligence document extractor system for workflow automation in various domains

A method for integrated workflow verification and document processing, the method comprising:

• executing a workflow instance comprising a sequence of events, each event of the sequence of events being associated with a timestamp;
• computing, via a computation and terminal digest generation subsystem and based on a cryptographic hash function applied to a previous digest value, serialized event data, and a timestamp-derived salt, a rolling digest for the sequence of events;
• upon completion of the workflow instance, generating via the computation and terminal digest generation subsystem, a terminal digest representing a final state of the rolling digest;
• detecting a generation of the terminal digest as a trigger event;
• in response to the trigger event, automatically initiating document processing for electronic documents associated with the workflow instance;
• retrieving the electronic documents using a workflow instance identifier common to both the sequence of events and the electronic documents;
• processing, by an adaptive template-based extraction subsystem, the electronic documents to obtain results;
• embedding the terminal digest as metadata within the results to obtain an embedded terminal digest;
• and
• storing the results with the embedded terminal digest.

A system for integrated workflow verification and document processing, the system comprising:

• at least one processor;
• and
• a computer-readable storage medium storing instructions, which, when executed by the at least one processor, cause the at least one processor to be configured to:
• execute a workflow instance comprising a sequence of events, each event associated with a timestamp;
• compute, based on a cryptographic hash function applied to a previous digest value, serialized event data, and a timestamp-derived salt, a rolling digest for the sequence of events;
• upon completion of the workflow instance, generate a terminal digest representing a final state of the rolling digest;
• detect a generation of the terminal digest as a trigger event;
• in response to the trigger event, automatically initiate document processing for electronic documents associated with the workflow instance;
• retrieve the electronic documents using a workflow instance identifier common to both the sequence of events and the electronic documents;
• process the electronic documents using an adaptive template-based extraction system to obtain results;
• embed the terminal digest as metadata within the results to obtain an embedded terminal digest;
• and
• store the results with the embedded terminal digest.

A method for providing workflow automation, the method comprising:

• logging, via a processor, event messages for a workflow to obtain logged event messages;
• computing a timestamp-salted rolling digest for the logged event messages using a hardware security module;
• embedding a terminal digest in an electronic message associated with a workflow instance for external verification to obtain an embedded terminal digest;
• performing an integrity verification check of the embedded terminal digest to obtain an integrity confirmation;
• and
• initiating, based on the integrity confirmation, processing electronic documents associated with the workflow instance using a workflow instance identifier common to the logged event messages and the electronic documents, wherein processing the electronic documents further comprises utilizing an extraction path having a transformer-based artificial intelligence model that generates new templates when a confidence score meets a threshold and when a layout hash does not match a cached template.
