Crot Plagiarism Checker
Block is based on document fingerprinting technologies for pair-wise document comparison.
Please note that as of August 01, 2012 the block does not perform global / Internet search due to monetization of Bing search engine API.
A distinctive feature of this plug-in is that all local checkups are happening on your Moodle server without sending any documents outside. Thus, in contrast to other available solutions, the plug-in does not impose any issues related to student intellectual property protection.
This module is the successor of Crot for Moodle block: http://moodle.org/mod/data/view.php?d=13&rid=2141&filter=1. This version is tailored for the plagiarism API in Moodle 2.x.
This is standalone module that doesn't require a connection to the external plagiarism detection service.

Error in moodle 2.5: Coding error detected, it must be fixed by a programmer: Invalid table name {plagiarism_crot_submission_pair}: name is too long. Limit is 28 chars.
It is giving an error of:
Strict Standards: Declaration of plagiarism_plugin_crot::get_form_elements_module() should be compatible with plagiarism_plugin::get_form_elements_module($mform, $context, $modulename = '') in /var/www-dev/moodle/plagiarism/crot/lib.php on line 37
I'm not sure what this error means to start fixing it.
I made a new assignment and submitted 2 fake but similar entries and it identified high % similarities. There are all sorts of dubugging errors but the functionality seems to work.
