P2P provides opportunities for law enforcement stings for C.P.



Saturday, at Shenandoah Valley Gay Pride, inside a restaurant called Artful Dodger on Court Square in downtown Harrisonburg, VA, I was seated in a small lounge area where there were some newspapers on a small table.  One small local newspaper was open to a story about a local man who had been arrested for child pornography found on his home computer, about thirty images, simply when an undercover state police officer discovered them through a P2P connection.

I found it interesting that the printed article seemed to have been read and noticed by several people.  That’s a good thing.

People have used P2P for years (I don’t), but it may become even more popular soon as companies promote “the distributed web” and block chain use.
  
However users need to be aware of this.  CP can also be detected in cloud backups and email attachments and image or video uploads by automated screening for hashmarks.  And harshmark technology is rapidly developing.

It's well to review the CPPA and its replacement, the Protect Act of 2003



I generally try to keep up with news that happens in my own court, even small incidents that stay relatively private. That remains so even when the media is so filled with sensational international affairs.
  
This is a good time to review the CPPA of 1996 (presented here Aug/ 17, 2015), which would have made it a crime to put simulated c.p. online even when there is no actual minor.  It was struck down as unconstitutional in 2002 (after considerable outcry in the artistic community on First Amendment grounds), but replaced by a “Protect Act” of 2003 under the first Bush administration. It can be illegal when there is explicit sex shown, and/or when the item is legally obscene or lacks legitimate value.  Here is the Wikipedia reference (look for paragraph 1466A).

In many countries overseas,  simulated or hand-drawn c.p. is illegal.  People who have posted images or video that is legal in the U.S. should bear this in mind if they travel overseas and if their content is available in the country they visit. .

Ironically, possession of c.p. is legal in Russia (CNN story ).  That’s even more surprising given the tone of the 2013 “anti-gay propaganda law” and the Russian idea (even espoused by Putin) that homosexuality is connected to pedophilia.

Wikipedia link for  DOJ Protect our Children banner, was used against Backpage which was seized before FOSTA became law.

Police use K9 dogs to look for digitally stored child pornography (NBC story)



Scott MacFarlane et al have a story on NBC Washington about the use of K-9 dogs in police searches of homes or offices to look for child pornography.
  
The dogs can detect the scent of thumb drives, San disks, and the like, which could be hidden away from possible police searches. 

Of course, people may hide thumb drives or put them in safe deposit boxes as part of completely legitimate home security concerns.
  
A more important development might be the little reported practice of scanning email attachments (even when someone sends an email to self to move it to a different computer) and even cloud storage for watermarked child porn images matched against law enforcement databases.  This has resulted in spotty arrests (at least one in Houston, one in southern Maryland).
  
You wonder if this practice could extend to other illegal behavior, like even storying copyrighted images without publishing them.

"Child Limits and the Limits of Censorship" paper by Protasia foundation, urges moderation in platform enforcement of TOS standards



The Protasia foundation has an important article, “Child Protection and the Limits of Censorship”, on medium, by Jeremy Malcolm.

The article discusses the downstream liability issue in general for service platforms, and explains clearly (near the end) why it opposed (Backpage) FOSTA (now under a lawsuit filed June 29 by EFF) as going after parties distant from real sex trafficking.


It discusses Microsoft’s PhotoDNA system, as to its future implementation by platforms to prevent copyright infringement (it mentions the Copyright Directive and Article 13 issue, which thankfully has been tabled for a while this morning) and possible child abuse. It also discusses the problem of image hash lists (or watermarks) at a higher level.

It discusses the termination of user account when users may have inadvertently handled images marked by NCMEC; apparently not all of these are technically illegal under child pornography laws.
It also gives other examples of overzealous enforcement of “grey” areas shutting down many users, such as a case with Wikipedia in Britain
