As an instant messaging service, of course data security and user privacy will always be the most important. For example, WhatsApp services, for example, Facebookwill present advertisements on this service, but the ad recommendation data is not taken directly from WA itself but from Facebook activities, users who use the same number.
Thus the security and privacy of its users will remain safe and secure, even though one day it can still be broken, but certainly everything has been anticipated by Facebook to see its history so bad throughout 2018 yesterday.
Now, to add more security to the plan, WhatsApp is working on an authentication mechanism using fingerprints embedded on most Smartphone devices. If indeed this happens, it will be something extraordinary.
The WhatsApp fingerprint sensor feature itself was first known after the developer launched the WA application update for Android users version 2.19.3 for the Beta program on Google Play. Reportedly for this authentication method will later use a third-party locking application called Redundant.
The users will find a new session in the application which is a special option to enable or disable the fingerprint feature. With this feature activated, users will be asked for fingerprint data every time they open the WhatsApp application. Not only on Androiddevices , it is reported that this feature will also be present on iOS devices .
From the information conveyed by a reputed leaker , namely WABetaInfo, for now the feature is still in the further development stage. Just a knowledge that previously the most popular instant messaging service in the World also had time to develop similar features, namely authentication of Face ID and Touch ID for WhatsApp applications on iOS devices. But unfortunately for these features it cannot function properly.
