Question
Can u please inform whether an AI solution exist to compare numerals and signatures. If so, is it being used commercially?
If the finger print is captured in the data base, whether AI can be used for comparing the finger print(using Ink) on an instrument like Check?

Answer
Yes there are many algorithms that compare symbols (numeral, signatures, images etc). Its called "pattern recognition" in AI and is an intensive field of research. As for finger print recognition, see:

Expertise

I can answer most of the questions about the workings of a Fuzzy Logic machine, from the basics up to a certain advanced point.Questions regarding applications of Fuzzy systems intregrating with other technologies such as Neural Nets or Genetic Algorithms are propably out of my reach although,with some research,i could try to answer them(i have working knowledge of Neural Nets an Genetic Algorithms but i`m far from being consider an expert to these areas).

Experience

I have experience in Fuzzy Logic gained in projects i have been part of.The last project was a robotic vehicle that used a Fuzzy Logic path tracker which i designed.
