Imaging System of Remaining Information of Fingerprint in Paper
This article elaborates on the testing principles and working procedures of the remaining trace on paper (mainly invisible fingerprints of sweat). In order to keep the original testing samples intact, a new method is proposed to test and get image of the invisible of fingerprints of sweat. The new approach is to test the difference on resistance between the remaining trace in paper and non-remaining trace, and input the tested data into computer. This approach makes use of software to convert the tested data into image and some method to obtain a keener image.
