Abstract
Systems and methods are provided for access control enforcement through real-time packet inspection and transaction screening. The system employs one or more processors and memory to execute instructions that analyze packet headers and payloads, enforce access control policies, and utilize machine learning-driven agentic systems to predict associations with sanctioned entities. By comparing packet data against sanction lists and employing hierarchical decision-making processes, the system blocks or flags high-risk packets.
Claims20
A method for improving transaction screening accuracy, comprising:
- using machine learning systems trained on historical transaction data to perform screening operations by:
- dynamically adjusting screening thresholds and predefined criteria based on past outcomes, thereby generating adjusted screening thresholds and adjusted predefined criteria;
- executing cascading decision trees to evaluate the adjusted predefined criteria and decision-making steps using a hierarchical rules engine established by:
- defining the cascading decision tree nodes with the adjusted predefined criteria,
- incorporating artificial intelligence models at each decision node, and
- setting threshold values and weighting factors for transaction analysis;
- and
- generating evaluation outputs comprising:
- detection accuracy metrics for each decision node;
- identified patterns in false positive triggers;
- and
- recommended threshold adjustments.
