Technology researcher Jane Manchon Wong revealed in her blog a new feature tested by Facebook for Android phones.
The feature, which has not yet been released, is intended to extend the original feature of Wi-Fi Search that was first introduced two years ago, according to the Reclaim The Net technical site.
Facebook explained that the Find Wi-Fi feature is designed to help users of social networks that may travel frequently or for any other reason, such as the inability of a person to use the data from his phone.
Jane explained that the development of the feature is that, if enabled, this feature will allow "Facebook" to periodically know the location of the user.
This is done so that Facebook can connect network data in a large cell.
Jane predicts that Facebook could have access to the vast list of these large residential networks by collecting user data that allowed the app to access their sites.
Apps on Android devices are allowed to collect this type of data from time to time to facilitate sharing with advertisers.
"By outsourcing Wi-Fi networks and linking them to geo-location data, companies can identify the relationships between users, for example, whether they are roommates, neighbors, colleagues, or business associates." their place of work, etc. This allows ads to be targeted more precisely. "
