The disguising of signatures is the most common practice in white collar crime. In case of disguise, people deliberately change their usual pattern of writing including signatures with the intent to deny the authenticity of the same in future for some obvious benefits. There may be numerous methods to disguise the original handwriting and signatures depending upon the capability of the writer and intention behind disguising. In the present case study, the subject has disguised his own signatures by putting the alphabets in lateral expansion instead of usually used overlapped alphabets. A critical study was done to decipher the rare methodology of disguising using technique of lateral expansion. Copyright@ International Science Community Association
