This is a must-read for anyone living in the digital age. It's a call to action for everyone from security experts to politicians to citizens.

Very valuable information.

Couldn't get through the entire book. I love the concern he has for society in general and the amount of data being captured, manipulated, and controlled. I also like some of his suggestions for improvement (as I've skipped ahead in the book).

Would probably need to re-read completely if I decided to get into this topic into more detail.

skimmed this one, basically bad for big government to control big data, probably not good for all the companies that we buy/charge from having all that info either

Author makes some remarkably conclusory statements assigning malice or ill intention without any support.

This is a good telling of how data used to be collected versus how (and how much) is collected now. Or, rather, in 2015 when it was published. It’s probably worse now. But it’s a good primer on privacy and surveillance, how much our government does, and some steps we can take to counter it.


The book was 383 pages long, but the entire last 150 or so pages are endnotes.

If you've never heard of Ghostery or Disconnect, go ahead and look them up. Try out their web browser extensions (you can always easily uninstall them). What you'll notice is that you're being tracked by many companies, some of which you've heard of, but many of them will be unfamiliar. There aren't just a few companies tracking you, but well over a thousand. And it's not just companies that are tracking you, but governments as well (this should already be obvious). What's great about this book is that it doesn't go into much technical detail, which is great for nontechies; it just gives you an overview of what's happening to your data as you browse around online and offers some suggestions on online privacy.

Disagree with the premise, but it was convincingly and cogently argued. I think the likelihood of rolling back big data surveillance as Schneier hopes is next to 0, too. As a summary of the general collapse of any reliable form of privacy in an age of big data, this pretty much hits it on the head.

Excellent overview of the current issues surrounding privacy and surveillance. Highly recommended

A must read to understand how our privacy is increasingly under attack from both for-profit corporations and governments under the guise of providing personalized user experience and services and in the name of security. How mass surveillance by corporations is being done without the knowledge of the user and how dangerous all this hoarding of data is by both corporations and government.
