The biometric security as has become a usual aspect in many smartphones. Its most widespread are the sensor footprints and today we find, not only in high-end mobile, but also in the medium range and in addition there are several technologies available. the Samsung has already tested several technologies and could gamble for a new one with the Samsung Galaxy S8.
The sensor tracks of the last Galaxy S is mounted in the home button front and is capacitive, but there could be changes in this piece. According to rumors, Samsung wants its next flagship to be “all screen” and that would mean the elimination of the sensor fingerprint, which would be under the own crystal and it could be optical, but is this the best option?
what optical Sensor or ultrasonic?
there is Still enough for the arrival of the Samsung Galaxy S8, but the interest that this range, combined with the vacuum left by the Galaxy Note 7, makes the rumors intensified, and the latter continues to support the theory that the next model would follow the line of “all-screen” that is rumored on the iPhone 8 and yesterday we saw with the Xiaomi Mi Mix.
To be able to get the screen occupies the entire front without sacrificing the fingerprint reader, Samsung would from a capacitive sensor to one optical that would allow you to integrate them under the glass, although for that there are technologies more appropriate Sense ID from Qualcomm, which works using ultrasound technology.
To learn more about this hypothetical decision we have consulted Umanick, a start-up Spanish that is dedicated to the biometric security in healthcare. According to Ilko García, CTO of Umanick, the optical sensors reflective capture a two-dimensional image that it is much more easy to replicate, while the capacitive sensors as the one that now leads the Galaxy S7 will add a plus to take into account the irregularities of the fingerprint.
in Addition, the optical sensors are, generally, larger than the capacitive (although there are variants that allow you to create smaller pieces), they consume more and are sensitive to light, so they are not the best option.
We are especially careful with the rumor of the optical sensor in the first place because its implementation would mean a step backward in terms of security. In this sense, as we said the integration of a sensor with the technology of Qualcomm sounds more plausible, for security and because it is easier to integrate in the panel.
on the other hand, in regard to the possibility of Samsung ahead of the launch date of the Samsung Galaxy S8, a director of the company has confirmed that all the controversy of the Note 7 has not caused changes in your usual schedule, so we can expect the Galaxy S8 to the end of February to coincide with the international fair Mobile World Congress, the regular appointment of the brand.
