Obfuscation: A User's Guide for Privacy and Protest
With Obfuscation, Finn Brunton and Helen Nissenbaum mean to start a revolution. They are calling us not to the barricades but to our computers, offering us ways to fight today’s pervasive digital surveillance—the collection of our data by governments, corporations, advertisers, and hackers. To the toolkit of privacy protecting techniques and projects, they propose adding obfuscation: the deliberate use of ambiguous, confusing, or misleading information to interfere with surveillance and data collection projects. Brunton and Nissenbaum provide tools and a rationale for evasion, noncompliance, refusal, even sabotage—especially for average users, those of us not in a position to opt out or exert control over data about ourselves. Obfuscation will teach users to push back, software developers to keep their user data safe, and policy makers to gather data without misusing it.
Brunton and Nissenbaum present a guide to the forms and formats that obfuscation has taken and explain how to craft its implementation to suit the goal and the adversary. They describe a series of historical and contemporary examples, including radar chaff deployed by World War II pilots, Twitter bots that hobbled the social media strategy of popular protest movements, and software that can camouflage users’ search queries and stymie online advertising. They go on to consider obfuscation in more general terms, discussing why obfuscation is necessary, whether it is justified, how it works, and how it can be integrated with other privacy practices and technologies.

Obfuscation is the deliberate addition of ambiguous, confusing, or misleading information to interfere with surveillance and data collection.
The underlying driver for considering the deployment of obfuscation techniques is due to asymmetrical relationships, characterized by an imbalance in power in a relationship, especially one in which a weaker force seeks to redress the balance in the relationship with the adversary.
Now you know this, you can start reading...
This short but powerful little book of 100 pages is presented in two sections. It begins with a ‘two-chapter’ section on the vocabulary of obfuscation, and cites many interesting cases of the application of obfuscation techniques such as using chaff to defeat military radar, or filling a channel with noise using twitter bots, through to using excessive documentation to make analysis inefficient.
The second chapter provides many thought provoking and varied examples, including, for example, using software add-ons to click all the advertisements on a web page or swapping loyalty cards to interfere with the analysis of shopping patterns.
The second section helps us to understand obfuscation, consider why it is necessary, if indeed it is justified, and whether it will work. In considering whether obfuscation will work, you need to define your project, and if you want to use obfuscation techniques, you will need to decide which of the six goals below are appropriate:
to buy some time
to provide cover
for deniability
to prevent individual exposure
to interfere with profiling
to express protest
Other questions to consider in your project definition are: is it to be carried out by an individual or does it require collective action; does it matter if your adversary knows or not; is it designed to be directed at a specific adversary (selective) or at a anyone who might be gathering and making use of data about you (general); and finally will it be over a short-term or long-term time-span?
The sheer volume of research that has been required to produce this editorial is well evidenced in the chapter notes towards the end of the book, supplemented by a further bibliography. As you would expect the text is extremely well indexed.
In summary, an enjoyable read, probably best read in two sessions - one section per session.

Not so much a how-to book, this is more of a why-to, with some examples included that provide some ideas of what-to-do. Many of the examples are from the non-IT world, like radar chaff and the use of common masks or uniforms to temporarily confuse the police in the immediate aftermath of a robbery. But there are also examples of internet-era technology obfuscation, including Twitter-bots hijacking hashtag terms, and services that robotically send out streams of unnecessary searches in order to hide the handful of critical searches in the volume. There is certainly plenty to think about, and the authors do a good job of covering the pros and cons of obfuscation, including ethical considerations. This is one of those books that, although relatively short, will have a continued impact on how I think about obfuscation as a tool for the weak against the powerful, and it points up some additional risks of relying on data for optimization algorithms when that data could have been sabotaged.
In one section, the authors described obfuscation involving colluding people in a group that all claimed a single identity or claimed to be the cause of some action. Ah, I’m thinking, I know of this. Then the authors use as an example a scene from the movie “Spartacus,” where the slaves are asked which one is Spartacus, and all slaves claim to be Spartacus, a group act which saved Spartacus’ life. I found it funny that I was thinking of a movie as well, but it was “Seven Brides for Seven Brothers” to illustrate the same thing the same way. I’m not sure what to make of this, but it strikes me as funny.

Fairly scattershot and overwrought. The chapter on ethics (unfortunately the longest) felt very out of place and was not greatly informative, contributing to the book as a whole feeling more like an academic essay rather than a "guide" to anything. The most interesting thing I got out of it was some insight into generalized "classes" of obfuscation or contamination that might be present in a dataset that one is analyzing, allowing one to compensate for them the analysis, though this idea wasn't explicated in the text. A fairly quick read, but I think I could have done without nevertheless.

The subtitle of this book is misleading; it's not a user's guide at all, but more of an introduction to and moral defense of obfuscation practices.
April 16, 2019
This was disappointing.
This book has two parts. The first part (chapter 1 and 2) is an introduction to obfuscation and has lots of examples. It's a great introduction, a mind-expanding survey of the design space for obfuscation techniques. Unfortunately, that's where the practical bit ends. With part two, the book devolves into armchair-theorising about the ethics and ontology of obfuscation.
Chapter 3 says some interesting things about information asymmetries. The authors quote Anthony Gidden's idea of manufactured risk to state that surveillance doesn't just reduce risk, it also exports it. For example, data collection by credit agencies may protect us from one class of risks (insurance at lower premiums), but create another class of risks (hacking of collected data, sharing without consent, so on). Further, data collection usually reduces risk for the many at the expense of increased risk for the few (and this increased risk is distributed differently along different socio-economic axes, mostly affecting the already marginalised). The authors also mention James C Scott's book Weapons of the Weak on peasant resistance against asymmetric power relations and promises that this book continues in the same vein to show how obfuscation can be a tool of protest against information-asymmetric relationships of power (it hardly does, and I really wish it did).
The main takeaways of chapter 4 were ethical guiding principles for applying obfuscation; they make the utilitarian argument ("blocking a data flow is unethical only when the data flow is ethically required"), the contextual integrity argument ("inappropriate flow of information/ legitimate use of obfuscation is normative") and the individualist argument ("how much privacy should the individual have to sacrifice for the common good?"). Nothing novel or ground-breaking.
Chapter 5 has six similar-sounding goals obfuscation achieves and four obvious questions to ask yourself if you're designing an obfuscation system. There are some practical titbits here and there in this book and but it largely fails to deliver on the promise of being a "user's guide". It's more of a "philosopher's guide" than anything else.

The book a collection of starting points for understanding and making use of obfuscation.
It is split into two parts - an analysis of the possible applications of obfuscation and obfuscation as a strategy for privacy protection; the ethical issues obfuscation raises and salient questions to ask of any obfuscation project. The authors took care to emphasize that in addition to privacy, it is not a replacement for one or all of the tools which we already rely on.
There is no simple solution to the problem of privacy, because privacy itself is a solution to societal challenges that are in constant movement.

Decent, but more of a textbook than I was hoping for. The most interesting part was the first section where it talked about a lot of examples of obfuscation. TrackMeNot is a Firefox/Chrome extension that does random search queries in the background.

Decent, but the font was annoying to read and the thread of thought seemed cluttered and the narrative hard to keep cogent at times. Still, I'm glad I read this.

Nice little book with practical applications to ensure privacy for individuals; “getting your obfuscation work out into the world, where it can begin doing good by making noise.”
Quotes:
Obfuscation is the deliberate addition of ambiguous, confusing, or misleading information to interfere with surveillance and data collection.
Obfuscation has a role to play, not as a replacement for governance, business conduct, or technological interventions, or as a one-size-fits-all solution (again, it's a deliberately small, distributed revolution), but as a tool that fits into the larger network of privacy practices. In particular, it's a tool particularly well suited to the category of people without access to other modes of recourse, whether at a particular moment or in general-people who, as it happens, may be unable to deploy optimally configured privacy-protection tools because they are on the weak side of a particular information-power relationship.
Obfuscation, at its most abstract, is the production of noise modeled on an existing signal in order to make a collection of data more ambiguous, confusing, harder to exploit, more difficult to act on, and therefore less valuable.
This is not an argument against other systems and practices; it is merely an acknowledgment that there are circumstances in which obfuscation may provide an appropriate alternative or could be added to an existing technology or approach.
obfuscation is, in part, a troublemaking strategy. Although privacy is served by the constraints of law and regulation, disclosure limits imposed by organizational best practices, protective technological affordances provided by conscientious developers, and the exercise of abstinence or opting out, the areas of vulnerability remain vast. Obfuscation promises an additional layer of cover for these. Obfuscation obscures by making noise and muddying the waters; it can be used for data disobedience under difficult circumstances and as a digital weapon for the informationally weak.
Individuals have good reason to question whether their privacy interests in appropriate gathering and use of information will be secured any time soon by conventional means.
When entering the realms of the political, obfuscation must be tested against the demands of justice. But if obfuscators are so tested, so must we test the data collectors, the information services, the trackers, and the profilers. We have found that breathless rhetoric surrounding the promise and practice of data does not say enough about justice and the problem of risk shifting. Incumbents have embedded few protections and mitigations into the edifices of data they are constructing. Against this backdrop, obfuscation offers a means of striving for balance defensible when it functions to resist domination of the weaker by the stronger. A just society leaves this escape hatch open.

This is an important, if not terribly engaging, and thoughtful discussion of privacy presented in simple, compelling language.
I especially like the opening of Section 3.1 (titled "Obfuscation in Brief") with it's nuanced discussion of privacy and the closing of Section 3.2 (titled "Understanding Information Asymmetry: Knowledge and Power") with its argument that large organizations' data acquisition amounts to externalizing risk (the large organization can operate more efficiently or with more security, while the individual pays the price of breaches or abuses).
Almost half of the book is devoted to a dizzying array of examples of obfuscation. The point is to set the stage by showcasing the varied utility of obfuscation, whether executed by actors moral or not, technical or not, and even conscious or not. It's an impressive list.
my favorite quote: "The goal was not to construct an airtight lie, but rather to multiply the possible hypotheses so prolifically that observers would despair of ever arriving at the truth."

This is a good book for beginners who are interested in the topic of Obfuscation.
What I like about this book is that it's an easy read, and doesn't require a lot of technical knowledge to understand what its talking about. However, it kinda lost me during chapter 4, it kept talking about the topic of justifying Obfuscation over and over, like a rambling man trying to convince you with his ideologies. That doesn't mean the entirety of the book was like this. At its early chapters it had a nice way of presenting ideas in a fluid way that came full circle as you progress through the book, that is until you reach chapter 4. Chapter 4 felt like it was rushed and trying to compress a lot of information all at once.
I like to think that online privacy was always a topic of passion for me. I found myself intrigued and even smiling at a lot of points in this book.
I wonder how this book would have changed what I know about online privacy if I came across it in my younger years.

I didn’t really know what to expect when I saw this book, I had been meaning to learn more about privacy techniques and modern surveillance. What I got was a weirdly deep dive into this small albeit interesting slice of the conversation on privacy. Pretty interesting examples of obfuscations use, from radar chaff to the Craigslist robber, but I think a subtitle like “a users guide for privacy and protest” is a little misleading - I’m left with knowledge about obfuscation, but not much about the privacy space. It seems like there wasn’t a ton to say about obfuscation - the same points were reiterated many times, and the language is unnecessarily verbose, to the point it clouds meaning.
Tl;dr it has piqued my interest ability security, but it’s pretty low ROI in terms of knowledge and understanding

This book is so NOT what the title proclaims it to be.
There is no user's guide here, just yadda-yadda that comes off like a prosecutor's opening speech (what we intend to prove here . . .) or a school paper of the BBB variety.
There is virtually nothing useful to the "user", in the sense of how-to, or even much concrete in the why-to or what-to.
I really wanted a how-to, since privacy has become so difficult to maintain, even minimally, unless you can go off-grid. And with some advocates claiming that with the use of a British company, the political parties can gather enough data to craft personalised approaches to individuals for their campaigning, it's getting downright scary.
But this book was no help.

A nice short intro for obfuscation. Not a practical manual for those interested in practicing obfuscation, but may be a good gateway for further research.
The most interesting part for me was the ethical and political arguments. Of course a book of this length cannot go in depth with those issues and takes a rather broad and shallow approach. However, it is probably enough to inspire one to dive into deeper material.

This is a really inspiring book, describing the everyday problem of power asymmetry between the people vs big organizations (governments/corporations/what have you.) Opting out of this relationship is untenable, and so what are we to do? The book's answer: obfuscation. Obfuscation is the "weapon of the weak," allowing us to resist without needing to revolt. Short and sweet, and well worth the price of admission.

Very short book on Obfuscation. First part was informative to me, being new to this as it covered different techniques used in the past including WW1 and mentioned possible software that you could use currently. However, most of the book dealt with the types of obfuscation and the moral issues of obfuscation which I was less interested in.

Deliberate act to interfere with surveillance and data collection. use to buy time, provide cover, deniability, prevent individual disclosure, interfere with profiling, express protest.
Privacy protection and ethical concerns for both those collecting and those who are subject to collection.
Not so easy to "opt out".

An interesting exploration of the history of and reasons for data obfuscation. Lots of fascinating and thorough examples, and I liked the discussion of the ethics of obfuscation and the different goals one might have for doing it. This was published back in 2015, so I wonder how these concepts relate to the mass violations of data privacy that are so commonplace in today's AI landscape.

Read half this book in every possible location in nyc and the other half from pictures in my camera roll on the plane :p so fun!!!
This little book is effective in communicating the patterns and purposes of obfuscation—an idea which I’ve recognized in many places since reading this, and which seems to be increasingly prevalent.

Good overview of obfuscation techniques with interesting examples from the physical and digital worlds. Aspects of this will likely only get more important - if nothing else a solid list of self defense techniques and tools to try to maintain some amount of privacy in these digital virtual times.

Short book that goes over methods of obfuscation and reasons and justifications for doing so. I thought it was going to be more practical and less philosophical. Moderately interesting, but not mind-blowing. Good enough that I finished most of it in one day.

I found this to be an excellent dive into the world of privacy. I paused for reflection numerous times in this book to evaluate the world around me.

Part I is interesting enough, but less than 40 pages.
Don't waste your time with Part II. It's a repetitive lot of navel gazing reminiscent of a term paper.

Title obfuscates the contents. Not a guide. Should be titled: the politics and ethics of obfuscation. Interesting arguments but completely irrelevant to absolutely everyone except academics.

Pragmatic, amusing, philosophical, concise. Definitely a book I enjoyed reading overall, but occasionally quite dense in prose.

Basically a rundown of the different types of obfuscation, which refers to the strategy of mixing noise to signals to slow down or inhibit detection or catch-up by observers, enemies or competitors.

This is a fantastic book. I highly recommend you stop whatever you are reading now and pick this one up instead

A great introduction, but too brief at times.

Interesting ideas...but could have been a blogpost (and a paper).
