The Facebook app for Android uses a feature called “Global Collector Library” to collect information related to the user's system libraries and send them to its servers companys.
Of course, this is not new, since many times the company has been "caught" collecting any data from its users. The new thing in this case would be that she was not interested in the data, in a parallel universe ίσ .maybe.
Jane Manchun Wong, an application researcher from Hong Kong, discovered that Facebook's Android application scans the phone, creates lists of system libraries and uploads them to a social network server.
Jane he says:
The Facebook app for Android scans system libraries from its user's phone in the background and uploads them to their host. This is called the Global Collector Library on FaceBook, also known as GLC in the application code.
It periodically uploads the metadata of your system libraries to the company server. There does not appear to be an opt-out option for the Facebook Collector Global Library, nor does it appear to be able to display what has been uploaded to our devices.
We do not know what the purpose of the GLC is, but I suppose it can be used to determine system compatibility.
The Facebook application compresses each file before sending it to its servers to minimize traffic.
It is currently unclear what the purpose of this data collection is, what Facebook is doing with the data and whether this data collection is covered or referred to in the terms of service.
It may be some measure security, but who trusts Facebook;
