CFS - Physical Sciences: Documents
What We Do
Examine documents to determine whether they are authentic or if they have been altered, and to determine how they relate to a person, thing, event or time.
Authentication of documents by:
- comparing handwriting and signatures to identify or eliminate a particular writer
- comparing the pens, pencils, inks, paper and printing processes used to produce them
- examining them to detect and decipher erasures, indentations and alterations
