Detecting Inconsistent Values Caused by Interaction Faults Using Automatically Located Implicit Redundancies

This paper addresses the problem of detecting inconsistent values caused by interaction faults originated from an external system.This type of error occurs when a correctly formatted message that is not corrupted during transmission is generated with a field that contains incorrect data.When traditional schemes cannot be used, one alternative is resorting to receiver-based strategies that employ implicit redundancies - relations between events or data, often identified by a human expert.We propose an approach for detecting inconsistent values using implicit redundancies which are automatically located in examples of communications.We show that, even without adding any redundant information to the communication, the proposed approach can achieve a reasonable error detection coverage in fields where sequential relations exist.Other aspects, such as false alarms and latency, are also evaluated.
