wordpress plugin for PLAGIARISM

build a wordpress plugin to find copied content within that site itself. I find this tool [login to view URL] is useful. But it needs a lot of manual work to copy paste content and it has limit of 1000 words. The objective: To find if there is any copied content in my website. you may induce proxies or google search api or what ever requires. The tool should run in background on the server and provide the report with snippets of the copied content. How it should work 1. It should be in plugin format (installable and un installable ) 2. Count number of posts initially before it starts 3. Examine content post by post 4. Examine content each sentence 5. Google search each sentence with double quotes "" 6. If other URL coms in fist position then count that sentence as copied one. 7. Store all the copied data, urls(both copied from and copied to), in a different table for reporting 8. Rescan option 9. Resume the search automatically if it interrupts in the middle.
