was determined to be hacked the system removes this source from querying to enhance reliability and security once the filtering is complete step 741 the it is checked whether user identity is sufficiently validated step 743 if it is determined that the id check of the user is valid the process continues to authorization step 736 otherwise validation using human assistance is performed step 745 an id check of the identified user may be found to be validated when an mi score for one or more required fields either separately and or combined depending upon system settings is equal to or greater than one or more corresponding thresholds such as a corresponding mi threshold value mi thresh for example a combined score for all or select mi fields is calculated and compared to a corresponding mi threshold value mi thresh if the total mi score for each of the corresponding mi field s is greater than or equal to mi thresh the id check of the identified user is validated otherwise the id check of the identified user does not pass depending on the implementation the fields may be chosen by the system e g as required fields with other fields considered non required fields the system may then ignore the mi field s which are not selected at least until selected when for example determining a combined.
