Following on from the interesting discussion in my last post about the jpeg signatures, I undertook some quick testing on the impact of using / not using the EOF sections of a DROID signature file.
I previously posted this signature file here: http://dl.dropbox.com/u/59534857/DROID_SignatureFile_V55%20-%20no%20EOF.xml
I have compiled my results and written a brief paper that is available here: http://dl.dropbox.com/u/59534857/Comparing%20DROID%20signature%20files.pdf
I have included the summary section here:
“This short paper presents the results found when the End Of File (EOF) section is removed from the current Droid Signature (v55).
A second test is completed, in which the ‘Maximum Scan Bytes’ function is tested with the same signature files.
A recommendation is made to repeat these tests, and extend the scope of the source files.
A recommendation is made to consider the case for removing some EOF markers if there is an efficiency gain in doing so.
A recommendation is made to assess the impact of using the ‘Fast’ mode of Droid v6.”
Thought, comments and questions welcomed as ever.
