Synopsis: it’s possible to effectively conceal sensitive information inside language without raising eavesdropper suspicion using deep learning. This has important implications for secure communication.

Steganography has been used for ages to communicate information in a hidden manner. A natural question: how is this different from cryptography? Isn’t cryptography a very well-studied field in which two individuals aim to share information with each other without an eavesdropper being able to discover this information? Indeed, these two areas are very similar, but there’s an interesting property of steganography that takes information sharing to a whole different level: the information is shared without an eavesdropper even knowing that anything secret is being shared. What’s the use of, say, Shor’s algorithm (for breaking RSA encryption in polynomial time using a quantum computer) if you don’t even know what to decrypt?

Steganography has long been associated with painting and visual art. Painters often hide signatures, self-portraits, and other secret messages within their works as an “inside joke”. One such example of this is Jackson Pollock’s “Mural”, wherein Pollock hid his entire name in plain sight in the curvatures of the work.

Until recently, however, computational steganography methods for images (such as appending bits at the end of a .jpg file or applying mathematical functions to select RGB pixel values) have been easy to detect and uncover, and hand-crafted ones are difficult and not scalable.

In 2017, Shumeet Baluja proposed the idea of using deep learning for image steganography in his paper “Hiding Images in Plain Sight: Deep Steganography” [1]. In this paper, a first neural network (the hiding network) takes in two images, a cover and a message. The aim of the hiding network is to create a third image, a container image, that is visually similar to the cover image and is able to be used by a second neural network (the revealing network) to reconstruct the message image via the revealed image (without any knowledge of either the original message or the original cover). The loss is defined by how similar the cover and container images are and how similar the message and revealed images are. The concept was expanded upon a few months later by Zhu et al. to allow for arbitrary data encoding into images [2]. The results were astounding: the network was able to create container images that looked very much like the cover yet allowed the revealing network to reconstruct the message very closely.

While this result was very interesting, we felt that the utility of steganography specifically for images is limited.

messageformat is Working Hard to Make Themselves Obsolete

messageformat is an OpenJS Foundation project that handles both pluralization and gender in applications. It helps keep messages in human-friendly formats, and can be the basis for tone and accuracy that are critical for applications. Pluralization and gender are not a simple challenge, and deciding on which message format to implement can be pushed down the priority list as development teams make decisions on resources. However, this can lead to tougher transitions later on in the process with both technology and vendor lock-in playing a role.

Quick note: The upstream spec is called ICU MessageFormat. ICU stands for International Components for Unicode: a set of portable libraries that are meant to make working with i18n easier for Java and C/C++ developers. If you’ve worked on a project with i18n/l10n, you may have used the ICU MessageFormat without knowing it.

To find out more about messageformat, I spoke with Eemeli Aro, Software Developer at Vincit, and OpenJS Cross Project Council (CPC) member. Aro maintains the messageformat libraries, and actively participates in various efforts to improve JavaScript localization. Aro spoke on “The State of the Art in Localization” at last year’s Node+JS Interactive. Aro is an active participant in ECMA-402 processes, runs the monthly HelsinkiJS meetups, and helps organise React Finland conferences.

How do formats deal with nuances in language?

It’s all about choices. Variance, e.g. how the greeting used by a program could vary from one instance to the next, gets dealt with by having the messaging format that you’re using support the ability to have choices. So you can have some random number coming in and depending on the choice of that random number, you select one of a number of choices. This functionality isn’t directly built into ICU MessageFormat, but it’s very easily implementable in a way that gets you results.

We need to decide how we deal with choices and whether you can have just a set number of different choice types. Is it a sort of generic function that you can define and then use? It’s an interesting question, but ICU MessageFormat doesn’t yet provide an easy, clear answer to that. But it provides a way of getting what you want.

What are the biggest problems with messaging formats?

Perhaps the biggest problem is that while ICU MessageFormat is the closest we have to a standard, that doesn’t mean it is in standard use by everyone. There are a number of different other standards. There are various versions that are used by a number of tools and workflows and other processes in terms of localization. The biggest challenge is that when you have some kind of interface and you want to present some messages in that interface, there isn’t one clear solution that’s always the right one for you.

And then it also becomes challenging because, for the most part, almost any solution that you end up with will solve most of the problems that you have. This is the scope in which it’s easy to get lock-in. Effectively, if you have a workflow that works with one standard or one set of tools or one format that you’re using, then you have some sort of limitation. Eventually, at some point, you will want to do something that your systems aren’t supporting. You can feel like it’s a big cost to change that system, and therefore you make do with what you have, and then you get a suboptimal workflow and a suboptimal result. Eventually, your interface and whole project may not work as well.

It’s easy to look at messageformat and go, “That’s too complicated for us, let’s pick something simpler.” You end up being stuck with “that something simpler” for the duration of whatever it is that you’re working on.

You’re forced to make a decision between two bad options. So the biggest challenge is it would be nice to have everyone agree that “this is the right thing to do” and do it from the start! (laughs)

But of course that is never going to happen. When you start building an interface like that, you start with just having a JSON file with keys and messages. That will work for a long time, for a really great variety of interfaces, but it starts breaking at some point, and then you start fixing it, and then your fix has become your own custom bespoke localization system.
