Development of latent fingerprints on compact disc and its effect on subsequent data recovery

Chance fingerprints may be found on every type of surfaces of contact and when they are latent, need to be developed by various methods. The type of surface on which latent prints are to be developed is one of the important factors when a choice for a method of development is to be made. The matter becomes more crucial when the surface is unique like a compact disc containing digital data. In this case, to develop the fingerprints is not the only matter to be taken care of but also, is very important to select such a method which may not effect the stored data and its retrieval. In present investigation, various methods have been tried to develop fingerprints on the writing surface of a CD and results are discussed with respect to their development as well as its effect on stored data and data retrieval.
