Meta Last Modified By Check


Contained within some files is a record of who last modified the file, specifically a username or a more detailed name available to the originating software.

This check raises a flag if an exact copy of the last modified by name is found in other submisions in the target files. It can be useful in detecting submissions based on another submission. It also checks agains the creator information of other submissions to see if any duplication appears there.


An example of this situation would be where one student sends their submission to a classmate. The classmate then makes alterations to their submission. Since both the original submission and the classmates own submission were edited last by the same person a flag would be raised.

In The Report

The meta last modified by information is present in the report for all submissions and can be reviewed in the individual submission summary.
