just like how bitcoin makes a block hash. the idea is simple. sha(file) and then compare the hash to known hashs from known porn files.
but here is the thing..
to have access enough to make a hash. they need the file data.. .. every byte.. unencrypted
so to be able to get every byte, they need access inside of peoples supposed encrypted icloud storage
and how do they do this. well unlike your phone. the icloud is THEIR server. their property. and so their terms and conditions of service of people uploading to THEIR storage can be changed with just a update of terms and conditions and then a update of the app that does the uploading to ensure files from peoples phones are not encrypted as they get uploaded to their icloud.
so there are risks that even your normal legal content can be accessed by them.
they 'promise' to only look at files that have been flagged as having the file hashes of known illicit material. but then its a question of. being able to view it all technically. but promising not to.. . means they are then open to being court ordered to look at other files by other agencies for other reasons.
When people will start to realize privacy is important, it might already be too late. They're taking away our freedom,
the secret to learn is..
you have the freedom to walk.. because feet
you have the freedom to talk.. because mouth
but when it comes to using something branded. whether its a forum. a megaphone, a convention stage. a phone.
your freedoms dont really extend to other peoples property or service.
its like grocery stores. its their business. they can ban you from entering their business if they want. they can ask you to do certain things too, like only buy 2 items. or stay socially distanced. or dont access certain area's
its there service. you have no freedom or rights on someone elses property.
so thinking facebook, this forum. or a icloud is your "right" is the wrong way of thinking. they are extending a courtesy and a condition which they can remove from their service.
never expect privacy on someone elses service/property. but accept their courtesy if they offer it. and if they take that courtesy away.. and you dont like it. find something else.
the only way services learn is from seeing a lack of customers due to a change they make. if they want customers, they will learn how to follow what customers want.
