Bio-metrics are physical or behavioral human characteristics to that can be used to digitally identify a person to grant access to systems, devices or data. Examples of these biometric identifiers are fingerprints, facial patterns, voice or typing cadence. Forensic science is a critical element of the criminal justice system. Forensic scientists examine and analyze evidence from crime scenes and elsewhere to develop objective findings that can assist in the investigation and prosecution of perpetrators of crime or absolve an innocent person from suspicion. Forensic evidence is useful in helping solve the most violent and brutal of cases, as well as completely nonviolent cases related to crimes such as fraud and hacking.

Among all the mechanical miracles of advancement, there is one that, in context, can reform reality. During the ongoing two centuries, there have been a few such revelations: power, radio waves, flight, atomic vitality, the Internet, and others. Be that as it may, today mankind remains on the edge of something totally new: nanotechnology.
To begin the clarification of nanotechnology appropriately, let us make sense of what is this “nano” some portion of the word. “Nano” is a prefix utilized in the decimal standard, which means one billionth piece of something; along these lines, nanometer, a standard estimation unit, is a 0,000000001 piece of a meter. To have the option to envision how little this worth is, let us allude to models. One inch is 25,400,000 nanometers. Indeed, even a progressively illustrative model: a sheet of normal office A4 paper is 100,000 nanometers thick (Nano.gov). Human hair is around 80,000 nanometers thick (Nanowerk.com). As a rule, “nano” in “nanotechnology” signifies “little, small.”
All in all, right now, precisely is nanotechnology? As per the U.S. National Nanotechnology Initiative, nanotechnology suggests the capacity to comprehend and control matter at measurements between roughly from 100 up to one nanometer; it likewise includes imaging, estimating, displaying, and controlling issue at the assessed length scale (Nanowerk.com). At the nanoscale, matter has novel properties; properties of materials act under nuclear and sub-atomic guidelines, and this is the reason nanotechnology is so best in class: specialists can deal with these extraordinary properties to make new devices and items in zones of science and designing (nnin.org). For instance, nanotechnology permits to develop materials and structures at a nuclear scale; this implies researchers can “manufacture” materials from particles and atoms.
Nanotechnology is still during the time spent improvement, however by and by, it would already be able to astound mankind with ponders that were incomprehensible quite a few years prior. For instance, there are unique carbon nanotubes that can transform into a fake muscle; there is a 3D printer that can print new malignant growth drugs; there as of now exist self-recuperating materials, for example, solid that fills in its splits to deliver structures that weave back together; infections were made that convert pressure into electrical vitality, etc. These and different developments are the start of another mechanical time (io9.com).
Nanotechnology is a moderately new part of science that can upset the truth we live in today. Nanotechnology works with issue at measurements between balanced hundred nanometers. This permits researchers to deal with the one of a kind properties that issue at such a little scope has. Self-recuperating materials, counterfeit muscle, and other superb developments are just the start of the new period of innovation.
