Re: I'll ask the obvious..
said by swintec:Details obviously are thin as to how the files were discovered. But the files can be examined without someone actually examining what's in them.
Ill ask the obvious, what was Verizon doing looking in users personal storage accounts?
The Center for Missing and Exploited Children along with law enforcement have a very large collection of previous exploitation that's used as part of the identification and/or prosecution of victims and offenders. They could easily share hashes of the files with various backup service providers for the detection of illegal content.
When a file is transferred, both the client and server generates hashes of the file to ensure that it was transferred correctly and successfully. The hash could also then be queried against previously and compared to a list of known images that have been shared or otherwise obtained. While a false positive is theoretically possible depending on the hashing technique, it is extremely remote and could easily double checked by authorities.
Or... Providers should already scan for virus protection, both for their sake as well as the consumers. It's not that hard of an extension to just classify the child porn as a type of virus and use the same mechanisms.
