Can a fingerprint be copied?
Yes. Almost all biometric features can be copied at varying expense. Fingerprints can be copied in the form of data sets, paper prints, wax molds, etc. It is possible with criminal technical methods to observe, analyze, and copy latent fingerprints unwittingly left behind on beer glasses or door handles. One of the oldest descriptions of a high tech copy procedure has been given in a novel from R. Austin Freeman [Freeman]: Take a plate of chromate gelatin, expose this plate with the slide of the fingerprint and wash out the surface. Thereby those locations which have not been hardened by light are removed, thus leaving a fingerprint relief. Whether the copy is recognized as such or is accepted as the original depends on the fingerprint sensor and the analysis algorithm. Ultimately, however, the specific use dictates whether copying is worth while at all and whether it can be harmful. In most applications, it helps very little if a forger can make an exact copy of his own finger. From optimized protection systems, one can expect that a copy will cause no damage.
How easy is it to copy a fingerprint?
It is relatively easy and inexpensive to copy the own fingerprint (may be compared with the manufacturing of a duplicate key). This may be done in the form of a rubber stamp which may be delivered by a stamp manufacturer on the basis of an electronic fingerprint template. Mechanical copies require as interim step a negative. Paper copies are made using a stamp pad. Copies from the own finger are a risk for systems for which the feint of an authentication by a complice can result in a damage (e.g., attendance system: feint of attendance by abandoning a suitable fingerprint copy to a colleague).
Much more complicated is the manufacturing of a finger image copy from a non-cooperative person (feature theft). Here one has to get access to a fitting fingerprint of the foreign person. One way is to find latent fingerprints. However, latent prints often
• are difficult to find
• have a quality which in fact allow a dactyloscopic analysis, but which are inapplicable to electronic fingerprint verification systems
• belong to the wrong finger
• show the false area
• cannot be gathered without leaving significant traces (e.g., graphite powder)
In security considerations often (but misleadingly) "cooperative victims" are supposed. To acquire the own latent print or that of a conscious contributor is relatively easy. It depends from the assurance requirement of an application whether a fingerprint authentication system must be able to distinguish between copied prints and authentic prints or if the fingerprint may be considered as a secret.
Are you referring to Sharon or Chris’s prints? If you’re referring to Chris’s prints, it might’ve been because as Sharon was her mom, Chris grew up within the bo, knowing that she would one day take her mom’s place. Hence, the BO would be able to give her the fake prints as mentioned above right from the moment she became an adult/was known to public.
Well, I agree that my statement was wrong. But I think that knowing the BO, they would be cautious at all time and as I have said earlier, , the BO might’ve given her the fake prints as mentioned above right from the moment she became an adult/was known to public.
Conan deduced that they were the same person because “the serial killer” wiped the blood and “Dr Araide” rescued him at the bus hijacking case. Wouldn’t it make sense if the “serial killer” was Chris Vineyard??? And since the one disguised as Dr Araide was also Chris Vineyard, she helped him and continued rescuing him after that to show her gratitude.
