WhatsApp already has a powerful search engine that allows you to find an image – or any other type of document, video, text… – in the application. However, in the future it may incorporate a second search engine centered on photographs.
“WhatsApp would use the Google API to access its image search engine.”
This is indicated by developers who have investigated the code of the instant messaging application and have found that in the beta version for Android is located this new functionality that would allow a user to “upload” to Google directly any image that came through one of your contacts.
By doing this, I would get more context information about the photograph and I could check if it is a montage or something real. WhatsApp would enable this new functionality as part of the fight it maintains to avoid misinformation and the proliferation of fake news on the platform.
It makes perfect sense to provide users with the possibility of obtaining more information about the graphic documents they receive. To launch this functionality, WhatsApp would use the Google API, which would allow you to use the search option on Android devices.
At the moment it is a function that is in the test phase, since it only appears in version 2.19.73 of the beta of WhatsApp for Android. In iOS you can not know if the same tests are being carried out, even if the integration of Google search systems for this purpose in iPhone mobile phones would be available.
