Documents


Documents are examined to determine whether they are authentic, if they have been altered and how they relate to a person, thing, event or time. They can be authenticated by comparing the pens, pencils, inks, paper and printing processes used to produce them and by examining them to detect and decipher erasures, indentations and alterations. Comparing handwriting and signatures can identify or eliminate a particular writer.
