Survey-Test Recognition of Forged Latent Prints

This a revised of the previous topic "Survey-Test Recognition of Fabricated Latent Prints" from Jan 7th, 2011
Hello Fellow Latent Print Examiners,
This is an invitation to participate in a survey - test for the latent print analysis - Recognition of Forged Latent Prints.
The identity of the participants will remain anonymous.
Purpose: The main purpose of this test is for training and testing the ability of LPEs to recognized forged latent prints. Even the chance to find this type of forged latent into a real case is extremely unlikely I think we as examiners have to be aware of it and be prepare to recognize it. The main reason of fingerprint forgery in the last years is for the purpose of breaking the hi-tech fingerprint security systems.
Eligibility: This test is for latent print examiners and requires analysis of 20 latent prints.
Testing implementation: You have to analyze 20 latent prints and then fill out a form with your answers, choosing between “Real” or “Forged” for each latent print. All forged latent prints in the test were left by couples of dummy finger obtained from molds. All latent prints were place on the same surface (white backing card) powder with black magnetic powder, then lift with clear hinge lift and transfer back to a white backing card. Most latent prints are high QQ, but there are couple with low quality as well.
The form is a PDF file. If you get the message "This operation is not permitted" when you open the file, just click "OK" twice and the form will be active. After it is complete you have to press the “Submit Form” button in the right top corner, or the “Submit by email” in the right bottom corner of the form. Some of the fields are required (marked with red) so if they are not filled out you cannot submit the form.
There is a text field on each latent print answer for comments if you have any. You can also add your comments, suggestions and thoughts about this survey at the end of the form.
You may fill out a fictional email or name in the fields after you press the “Submit Form” button since the form will automatically be submitted back with the data, regardless of what is written in these fields. This will keep the participation anonymous. After you submit the form you should get a message like this: “your response was successfully sent”. Please do not push the button more than once since it will be sent again. In case of an error message (if the form cannot be submitted automatically) you can save it, print, and then either email me back (ioan_truta@hotmail.com) with the PDF form attached, or fax it to 617-343-6024.
I will recommend to fill at least a nick name in Name Field. This way I can track the duplicates.
The anticipated deadline for participation is February 20th, 2011. My hope is to get at least 100 responses back. This survey test idea came to my mind when I was asked to present a seminar and I thought this will be an interesting subject.
You can use the this form and images as well for in-house training for new examiners. The answer key will be available after deadline date.
Download the images of the latents from this link as a compressed (.zip) folder. You have to extract the images from the zip folder on your computer.

The images of the latents are the same as in the previous topic. If you already download them you don't have to do it again.
The new PDF form has minor changes, so please delete the previous version and download the new one. For those who already submitted the old one, since the answers are the same the data is not affected.
Thank you for your participation in this survey.
