A Study to Focus on Augmentation of Pre-existing Methodologies for Tampered Document Examination

The most common types of cases encountered by the investigators are of Alterations, Additions, Erasures, Obliteration, invisible writings and charred documents. [...]several instrumental analysis techniques have been developed for the decipherment of the data from the destroyed Questioned document. The results were best seen in the documents which were recently erased. [...]it failed to give good results in case of documents which were not recently erased and time lapsed in their examination. [...]some advanced methods need to be devised which can be beneficial in charred documents handling as they are highly fragile. [...]there is an urgent need to develop selective scientific techniques and methods for the detection and decipherment of tampered documents which occupies the major areas in questioned documents so that the investigators can reveal facts and findings in the cases more accurately and in a speedy manner with a less chance of errors so as to avoid the damage of the questioned document.
