Child Abuse Imagery Found Within Bitcoin's Blockchain (theguardian.com)

German researchers have discovered unknown persons are using bitcoin's blockchain to store and link to child abuse imagery, potentially putting the cryptocurrency in jeopardy. From a report: The blockchain is the open-source, distributed ledger that records every bitcoin transaction, but can also store small bits of non-financial data. This data is typically notes about the trade of bitcoin, recording what it was for or other metadata. But it can also be used to store links and files. Researchers from the RWTH Aachen University, Germany found that around 1,600 files were currently stored in bitcoin's blockchain. Of the files least eight were of sexual content, including one thought to be an image of child abuse and two that contain 274 links to child abuse content, 142 of which link to dark web services. "Our analysis shows that certain content, eg, illegal pornography, can render the mere possession of a blockchain illegal," the researchers wrote. "Although court rulings do not yet exist, legislative texts from countries such as Germany, the UK, or the USA suggest that illegal content such as [child abuse imagery] can make the blockchain illegal to possess for all users. This especially endangers the multi-billion dollar markets powering cryptocurrencies such as bitcoin."

      I'm also not impressed by laws that criminalise possession of certain bits, be it cryptographic material, snuff movies, child porn, you name it. In the case of child porn, banning of pictures is not going to make children safer from harm. Instead, driving possessors more into hiding also makes the evidence of child abuse that much harder to dig back up and so makes it harder to find and punish child abusers.

      And, of course, the utter convenience of having handy the knowledge there'll be some stray files that just happen to be findable on someone's computer, like because it's running a full node and so has a complete copy of the blockchain, so you can prosecute your designated convictee-to-be whether he actually watched any child porn ever or not.

      You know, if someone distributes child pornography to discredit someone else, they're still guilty of distributing child pornography. Knowingly doing that would pretty much be a summary conviction in most places.

      Which would be awfully stupid.

      But, as I understand it, isn't the entire purpose of the block chain to act as a ledger of everywhere that coin has been? In which case the people who did this, and potentially anybody who had those coins afterwards, will be both identifiable, and potentially charged.

      So presumably, this can be traced back to individuals (or at least abstract entities, not entirely clear on that). And then the fun will really begin, because the why will be irrelevant.

      The problem bitcoin and other cryptocurrencies face is that it started out as the wild west, with people saying "yarg, teh regulations and laws don't apply". Well, financial industry laws and child porn laws have a long reach, and they're quite enthusiastically enforced.

    For a moment a few years ago I was interested in some kind of crypto messaging system loosely based on the concept of BitTorrent (I forget the name, like BitMessage or something) but your PC, acting as a node, basically got a copy of every message, encrypted, and your client could only decrypt the messages that were encrypted with your public key, so you could only read your mail. So far so good... if your PC had a copy of a message with illegal material in it, you'd have plausible deniability - there's no way you could read it without the recipient's key so no (sane) court would convict you for possession.

    The problem is the system also supported broadcast messages. So I could write a message encrypted with my private key, and everyone who had my public key could decrypt it. It offers a way of authenticating that a certain person sent a message. The problem is, now I've potentially got illegal content on my PC and since the key to decrypt it is public, I can no longer claim I can't read it. Any forensic group could grab my PC and "prove" that it had illegal content on it very easily. In fact, it allows someone to plant easily provable illegal content on everyone's PC. Bad idea.

    9. Re:Surprised they wouldn't have considered this by Anonymous Coward · · Score: 1

      I just wanted to elaborate on the parent, with regard to how "broadcast" messages are implemented in bitmessage:

      Addresses in bitmessage are a text representation of a user's public key. User can generate as many private/public key pairs (and hence addresses) as they want. Every user receives every message, and brute-force tries decrypting them with each public key, to see if it was addressed to them. This was designed to work like email: one-to-one messages. If you wanted to send to multiple different people, then you sent a separate copy of the message to each of them. A proof-of-work (hashcash) system is used to make the cost of sending each one of these messages high(ish), to try and discourage spam.

      Being limited to one-to-one messaging is annoying, so initially, bitmessage had a centralized mailing list system. These had 1 address (private/public key pair) associated with them. Any messages sent to this address were resent to the addresses of anyone who had registered with the mailing list. Becasue of the proof-of-work system,running a centralized mailing lists had a significant cost to the operator.

      However, in bitmessage, you also have the option to specify the random seed to use to generate keys, in case you want an easy way to recover the keys from a different machine without needing to memorize them or copy files (just use any sufficiently random but memorable string as a seed).

      If multiple users use the same random seed, then they all generate the same set of keys, and can use them to receive any messages sent to the corresponding address. So, for example, anyone who uses the "test" string to generate keys would get the same private key, and by extension they would be able to read any messages sent to the address associated with the "test" public key. Now users who want to discuss some niche topic can replace "test" with whatever topic they want, and suddenly they have a distributed uncensored anonymous forum in which to discuss it, with no public registry that the forum exists (though the seed can still be spread by word of mouth or posted publicly). Awesome on paper, but there are enough terrible real people to make this a nightmare, and as the parent said this kinda kills plausible deniability.

      There are scalability issues with this approach. Everyone-receives-everything falls apart as soon as you gain a significant number of users, which manifests as eating up a lot of bandwidth and disk space. Which means it's pretty much only useful to crypto enthusiasts who want to play with it, and people who actually have something to hide. If the majority if people who use an anonymous thing are doing something criminal with it (be it child abuse or something less morally reprehensible, like using the word "square" in china), then anonymity kinda goes out the door, since the mere use of it becomes probable cause that someone is up to something.

      This is in contrast with Tor, where things at least sort-of scale. You'll never get "normal" people to use a thing in mass if performance gets killed when you try to scale up the user base, and a large population of normal users is needed to provide cover traffic to anyone who does have something to hide (this is ostensibly why the US government released it to the public--an anonymous network does you no good if your intelligence assets incriminate themselves merely by using it).

      tl;dr bitmessage is pretty cool on paper, but IMO you shouldn't actually use it in its current state.

These numbers are pretty much picked arbitrarily to meet people's expectations (why for instance are they not automatically indexed to inflation).

You can in fact exterminate entire colonies of insects without major repercussions, but you can't cut down trees with a diameter larger than 6" w/o a city permit, except if it is a fruit tree. In many states, you can not kill a fetal pig (a chinese delicacy) to roast, but you can legally abort a human fetus. These laws are completely unexplained in a logical context using a "gold-standard", they are simply agreed to by society and the current boundaries of "acceptable" behavior. And these things change over time.

      "http://cointelegraph.com/news/113806/warning-kaspersky-alerts-users-of-malware-and-blockchain-abuse

      Warning! Kaspersky Alerts Users of Malware and 'Blockchain Abuse'

      Kaspersky Labs warns users of a possible exploit in cryptocurrency blockchains
      that would allow malicious actors to distribute malware or even images
      depicting child abuse.

      The warning is the result of research of INTERPOL Cyber threat experts, a group
      that includes a Kaspersky employee.

      They warn that the extra space provided in each transaction, intended for
      notes, messages and as a space to allow additional functions to be built on top
      of the blockchain, could in fact be used to spread malicious code or worse.

      Kaspersky's report states:

      "The design of the blockchain means there is the possibility of malware
      being injected and permanently hosted with no methods currently available
      to wipe this data. This could affect 'cyber hygiene' as well as the sharing
      of child sexual abuse images where the blockchain could become a safe haven
      for hosting such data."

      The blockchain, as CoinTelegraph readers are assuredly aware, is the virtually
      unmodifiable public ledger that acts as the backbone for the Bitcoin network.
      Once someone commits data to the blockchain, it is there forever unless more
      than 51 % of bitcoin miners decide to mine on a modified blockchain that
      doesn't include that data. That would be what is called a "hardfork" and would
      be extremely difficult if not impossible to pull off, with the current number
      of bitcoin users.

      Despite Kaspersky's recent warnings, storing illegal data in a compressed
      manner has been a concern for the Bitcoin community for a while. In fact, links
      to sites containing child abuse images have already been found in early
      blockchain blocks and storing an image in a hashed form has also been
      accomplished.

      Blockchain transactions don't provide enough room to store illegal images in an
      uncompressed form effectively. What INTERPOL and Kaspersky seem to be concerned
      about is either compressed, hashed, images on the Bitcoin blockchain or
      uncompressed images on alternative coin blockchains that allow for more space.

      Encrypted and compressed data needs to be uncompressed and decrypted with an
      algorithm. Theoretically, since an algorithm is just a set of rules to
      interpret data, any code can be turned into any other kind of code. Even the
      words of this text could, in theory, be "decrypted" into an image of the
      algorithm creator's choosing. It seems extremely unlikely that Bitcoin users
      would be subject to prosecution for possession or distribution of child
      pornography, when those images don't "exist" without proper decrypting
      software.

      A more realistic concern would be a small script embedded into the blockchain
      that either forces the download and install of more powerful code or somehow
      manages to run a damaging script in the few kilobytes of space provided. It
      seems it would be difficult to get those scripts to run without user
      interaction. Nevertheless, Kaspersky implies that even our private keys could
      be at risk.

      "[Blockchain malware] could also enable crime scenarios in the future such
      as the deployment of modular malware, a reshaping of the distribution of
      zero-day attacks, as well as the creation of illegal underground
      marketplaces dealing in private keys which would allow access to this
      data."

      Kaspersky stressed that they are believers in decentralized technology like the
      blockchain, but pointed out that their role is to identify threats before they
      become reality. At press time, there is no kno

    Possession of child porn effectively makes one an accessory after the fact to the crime of child sexual abuse. Paying for child porn probably makes one an accessory before the fact, because it funds and encourages additional abuse.

    If we apply legal theory about copyright infringement, then it turns out possessing child porn without paying for it is incredibly damaging to child porn intellectual property owners. Redistributing those images is basically putting child porn producers out of business. Isn't that a good thing?

In all of history, we're not going to generate a googol of numbers of that size (10^100), so the chance of randomly producing that number is less than one in 10^293,900.

      Therefore, if a number translates in some halfway reasonable way to an image or video of child pornography, that's what it is. If there are two extant numbers that can be combined to make child pornography, that's child pornography with the equivalent of a one-time pad.
