Forensic Analysis of Gurmukhi Letters based on Zone Division for Verification

Gurmukhi Language is a dominating language in northern states. Many documents written in this dialect become the subject matter of judicial scrutiny, where again much is left to conjectural analysis. It is a humble effort to devise scientific technology and tools for application to verify Gurmukhi handwriting - one disputed to be verified along with the genuine and admitted one. The rules and technology applied in English language is far less useful for the reason of its 35 original letters-consonants covered in three zones but more of them in upper and middle one; and frequent use of 11 diacritics - 9 of them being applied in the upper two zones of the writing. Accordingly, the paper makes a forensic analysis of two zones of writing because of their dominant use. Again, the relativity and aspect ratio methods of handwriting verification are worth bringing satisfactory results in determining genuineness of a handwritten document in Gurmukhi script subject to the judicial scrutiny. The researcher illustrates the application of relativity and aspect ratio along study of two zones of Gurmukhi language resulting in identifying the similarity or marked difference of the two writings.
