It was a nice month, with some casework, some work for the Forensic IT working group of ENFSI www.enfsi.org and developing new tools that are also used in casework such as http://prnucompare.sourceforge.net/, which were developed by our team. It includes now also wavelet methods published by Fridrich et. al. and batch processing, since these methods can be time consuming in calculation time.
It is good to see that work in literature is implemented in easy to use open source software, such that published methods in literature are available in the open source community, and it becomes easier to validate the different software approaches. We also have a database with some examples on line at http://forensic.to/prnu . Of course validation of the uniqueness of PRNU patterns with different cameras is always needed before reporting and drawing conclusions based on the results.
