It is possible that the other two fingerprints are either those of people who don’t have identification cards or driver’s licenses in France, or that the two fingerprints are that of someone who is not a French citizen. There are also a second and third set of prints that are not found in any French data base. Say like a French defendant is on trial for a crime committed in France and fingerprinting is being used to connect them to a crime because their fingerprints were found at the crim scene. This is an issue when it comes to international crimes – crimes that are committed in one country that are committed by someone born in or living in another country. First off, there isn’t one worldwide database where fingerprints are stored. The prints are then lifted with tape, special powders or digital readers and examined.ġ. Prints that come from crime scenes can come from everything from surfaces to objects to blood. Fingers are pressed in silicon or a surface that scans the prints and they’re converted to a pattern of data that can digitally be stored and compared to other data patterns. Today, digital technology has replaced the analog ink and pen techniques. The card would then pick up the print on the card. Fingers would be pressed into ink and then on a card, either rolling the finger from edge to edge, or just keeping it flat. For most of the time fingerprinting has been used in the US, it’s been done with ink and paper. There’s been a lot of debate about how precise the measurement and calculations are for fingerprinting and in the last 10 years there have been four different people who were once convicted on fingerprinting alone who have been exonerated based on new findings. In the last 15 years, fingerprinting has come under fire though. Until DNA profiling came along in the mid 1980s, fingerprinting was considered the most reliable scientific data source that could help convict people of crimes. To start, fingerprinting, more officially known as dactyloscopy, has been a tool that dates all the way back to the ancient Babylonians, but it’s been in use in the US since the 1858. Either way, finger printing is an interesting tool that is has been used a lot in the past to identify people… but is it as accurate as it’s reputation? Others are fingerprinted when they are incarcerated or if they are subpoenaed as a reason for authorities to think they might be part of a crime. They are used as something to prove that you aren’t someone else, and always as a way to track that your exist. ![]() However, as much as you might think it would be weird to walk up to your spouse and ask them to look at their fingers to make sure they’re really your spouse, fingerprints are something that are as unique to individual humans as our faces.įor the majority of us, fingerprints are taken when we get our driver’s license or ID. What you might not immediately think of when distinguishing people is fingerprints. Things like height, weight, and body shape definitely play into recognize people. There are specific body attributes that we might use to describe a person, too. Eyes, hair and facial structure are ways we usually give descriptions of other people and how they recognize people we know fairly immediately. When you look at someone you know, you generally might recognize them by something on their face.
