Mobile privacy versus snoopers

Avoid gossip nowadays it is quite complicated. The use of the smartphone during public transport trips or walking down the street is very common.

A developing technology

Technology under development to prevent gossip

Hee Jung Ryu and Florian Schroff, developers of this protection, assure that it works under various light conditions and that it is capable of detecting gossip in 2 milliseconds. One of the main problems that can appear is the continuous interruption of what we are doing and the loss of data.

In addition, another problem would be that a person continuously looked at the screen with the sole purpose of keeping it in this mode and preventing us from doing anything with our mobile. Either way, for now we are before a prototype of this technology, which has a long way to go. Its future implementation remains to be seen, but it is interesting to see how such a common problem is blamed from within Google.
