Sound-Proof: Two-factor authentication can greatly help protect your electronic accounts, but it's definitely an extra trouble. 
It is well known that some do not risk violating their accounts and thus use (we highly recommend) the time-consuming interaction with smartphones their.
But it looks like a new tool is being developed Sound-Proof. It is a new application designed to authenticate logins with ambient sounds.
The Swiss Federal Institute of Technology in Zurich, which is developing Sound-Proof, says:
With Sound-Proof, the second authentication factor is the proximity of the user's phone to the device used to connect. The proximity of the two devices is verified by comparing the ambient noise recorded by their microphones. The recording and comparison of sound is similar to two-factor authentication.
Η ερευνητική ομάδα λέει ότι η εφαρμογή Sound-Proof είναι εύκολη στη χρήση και λειτουργεί με τα σημερινά smartphones και όλα τα μεγάλα προγράμματα περιήγησης, χωρίς plug-ins – αν και θα απαιτούσε μια εφαρμογή για κινητά (ήδη αναπτύσσονται εφαρμογές για iOS και Android). Φυσικά χρειάζεται και μια σύνδεση στο Internet.
The tool only raises the digital signature of the sounds, not the real sounds, for an extra level of privacy.
It sounds very practical, but there are still potential problems.
Let's say the scenario of someone being on the same site as you and trying to hack your account with a known password access. ό χώρος θα μπορούσε να είναι μια καφετέρια μια βιβλιοcase ή ένα σχολείο.
Researchers admit this could happen, and try to resolve it.
