I know a lot of people in the security industry, & I know a lot of people who enjoy Facebook. However, there"s not much overlap between these groups. As someone who"s in both groups, I"m an oddity. Many security experts either always steered clear of the social network or are currently advocating deleting it. I closely follow security topics & products such as antivi khuẩn utilities, and I also use Facebook, but carefully. I don"t see any need to delete my Facebook account. But now that Facebook has made it so easy to download everything the social network has about me, I went ahead with that process. Perusing the resulting archive, I ran into lớn some surprises, both positive và otherwise.

I"m Careful, Really I Am

I"ve sầu known for years that with Facebook, I"m not the customer, I"m the sản phẩm. I keep my profile private except khổng lồ friends. I don"t post a lot in my visible protệp tin, và not all of what I display is true. For example, while it"s true that I studied Existentialism in college, I"m not actually a Pastafarian; I have sầu not been "touched by his noodly appendage." I never wildly click link that seem shady. And I maintain a security suite that warns if a dangerous links gets past my radar.

I never play Facebook games; you"d be surprised, or appalled, at how much data games can gather. I had khổng lồ silence one family member because of a Farmville tài khoản that kept pinging me lớn come play. I"ve been known lớn try some silly quizzes, but only the ones that ask you questions khổng lồ figure out, say, which trò chơi of Thrones character will kill you. Even then, the questions better not be the kind of thing that might answer your security questions. Those quizzes that offer to lớn scan your Facebook data và give you a result? Those are poison! I don"t touch them.

I never use Facebook (or my email account) to log inlớn websites. Doing so makes your Facebook password a single point of failure. One exposure và all your accounts are wide open. Instead, I use a password manager khổng lồ create strong, chất lượng passwords for every site.

But being careful myself isn"t enough. Sloppy security on the part of my friends can potentially make some of my information public. So I tightened up my settings to lớn keep Facebook from sharing my data. I went all-out, choosing the option khổng lồ totally disable the sharing platform. Facebook offered dire warnings about how doing so would disable my apps, and keep me from logging in using my Facebook credentials. I smiled & went ahead. Now I"m fine, right? Well, maybe.

Download Your Archive

These days, it"s easy to lớn download an archive sầu of all the data Facebook has on you. (At least, they say it"s everything…) Well, it"s fairly easy. You vì have sầu to lớn go through several steps, which are in place to lớn prsự kiện someone else from stealing your archive. Here"s how I did it, và how you can get your own archive sầu.


Log inkhổng lồ Facebook, cliông xã the down-triangle icon at top right, & choose Settings. On the General Settings page, cliông chồng the last chiến thắng, the liên kết to download a copy of your data. Facebook warns that collecting data may take a while. Cliông chồng Start My Archive sầu. On the next page, cliông xã Start My Archive sầu again, and wait for a notification that it"s done. Download your Facebook archive.

Note that you"ll have to supply your Facebook password twice during this process, because this is sensitive information. Facebook also warns that you should protect the downloaded data, as it contains sensitive material. Your best bet would be khổng lồ encrypt the data when you"re not actively studying it.

No Surprises, to lớn Start

Once you unzip the downloaded archive sầu, you"ll find you have sầu a folder containing a tệp tin INDEX.HTM plus folders named html, messages, photos, and videos. Ignore the folders for now; just launch INDEX.HTM & start exploring.

You start at the Protệp tin page, with general information about you & your Facebook trương mục. This includes the exact moment you started with Facebook (Thursday, June 28, 2007 at 8:15 a.m. PDT in my case) as well as your address (if you entered it), birthday, gender, hometown, & so on. It doesn"t distinguish between public details và those you"ve made private.

My archive sầu also lists everyone I"ve sầu identified as family members, all three dozen of them. Family connections are a big part of what keeps me on Facebook. The lists of Music, Books, Movies, Restaurants, & Websites I"ve sầu liked are short; I don"t tkết thúc to lớn give sầu likes in those areas. But the các mục of Other likes is more interesting. Apparently, I"ve sầu liked more than 60 pages, ranging from Notorious RBG lớn Thic Nhat Hanh to lớn "The Official Petition khổng lồ Establish "Hella-" as the SI Prefix for 10^27." At least Facebook doesn"t have a hellabyte of data on me...

This page also lists all the Groups I belong lớn. It"s a bigger danh sách than I expected, mostly because at least half of them haven"t had any activity for years. I"m not sure there"s any benefit in actively disengaging from moribund groups, though.

Friends và Not-Friends

Clicking the Friends links got me a list of all my Facebook friends, sorted from newest to lớn oldest. No surprise there! But scrolling down farther, I found a lot more. It also lists: Sent Friend Requests, Received Frikết thúc Requests, Declined Frikết thúc Requests, & Removed Friends. That"s right. Facebook knows everytoàn thân you"ve unfriended, và ever friover request you"ve denied, or ignored.

I dumped the list inlớn Excel for analysis, because that"s what I bởi. I found that several dozen of the entries appear in more than one category, & that some of these duplicates seem to lớn tell a story. Some years ago, I purged my friends list down lớn something manageable, but later added some of the purged folks baông chồng. And there they are—Removed Friends, but later, Friends. Others were persistent folks, Declined Frikết thúc Request followed later by Received Friend Request (which I ignored).

Possibly the most interesting category involve people who showed up in the Received Friend Request menu và no other. That means I received the request and just ignored it, without actively declining. I confess khổng lồ friend-request overload. And after ignoring requests for a while, it gets tough to lớn actively go through and decline the unwanted ones. To the 70 people in that category—sorry!

At the tail over of the các mục, I found a couple other minor categories. I have sầu exactly one Followee, meaning there"s one semi-public figure that I follow without actually being FB friends. You may have sầu more. Facebook"s analysis of my friend collection places me in the Frikết thúc Peer Group called "Established Adult Life." Why? Perhaps for advertising?

Who Are These Contacts?

The Friends page makes sense, though it includes more information than I thought it would. But the Liên hệ Info page totally mystifies me. It lists hundreds of people, in no apparent order, along with one, two, or three phone numbers. Who are these people, and where did they come from? The danh mục even includes entries for people no longer living, some of them deceased before I ever joined Facebook.

I dumped this danh sách inkhổng lồ Excel as well, và checked off any that I might have actually called on the phone. That accounts for just 10 percent of the list. About 6 percent of the contacts appear twice, most with the same phone number. Almost all of the names seem at least vaguely familiar, but not through Facebook.


For a sanity kiểm tra, I used an Excel formula to lớn flag every name from my Friends menu that also appears in the Contacts các mục. That accounts for 11 percent of my friends. Looking the other direction, because there are more Contacts than Friends, just 6.5 percent of my Contacts match the Friends danh sách.

I don"t know for sure how Facebook got this các mục of contacts and their phone numbers. I must have sầu given it permission to see my contacts on some platform, but even then, I mostly keep gmail addresses (notably absent from this list), not phone numbers. It"s a puzzlement!

My Whole Timeline at a Glance

At first, I was unimpressed with the page reached by clicking Timeline. Like many, I frequently post an image with a snarky bình luận. The Timeline view skips the images, and the snarky comments alone don"t make sense. Then I hit Ctrl+End, khổng lồ go to the over of the page. Wow!

Every post I ever made on Facebook is here in the timeline. I don"t know if it"s even possible khổng lồ go this far baông chồng within the Facebook user interface. If it were possible, it would take hours, maybe days, of scrolling down, down, down. I found the nearly ten-year-old posts fascinating. The post "feeling chilled after biking 10 miles in the rain Sunday to watch the Amgene riders start the first 100-mile ride" reminded me of the thrill of watching the opening of the first Amgen Tour of California bicycle race. And I was proud to lớn remember my grown daughter"s high-school success, Grvà Prize in a regional animation contest.

Even in this convenient one-long-page size, paging through the entire Timeline would be too much khổng lồ handle. But if you want to kiểm tra just when a certain event happened, an sự kiện you posted on Facebook, you can easily search the page for details. In effect, it"s an index for your entire Facebook history. What an unexpected treasure this is.

Every Phokhổng lồ, Awkwardly

Clicking Photos gets you a similar danh mục, a timeline of every pholớn or album you ever posted. It includes the date for albums, và any comments, but not the text you shared along with the album. When you cliông chồng through khổng lồ the individual photos, you don"t see the dates, unless the photo itself has comments. Facebook reports a raft of (to me) pointless information. Camera make và model. Orientation, width, & height. F-stop, ISO, và focal length. In my oldest photos, these are all the more useless because they"re often either blank or zero. I couldn"t figure out why some iPhone photos include a modicum of information, while others get nothing.

Some photos appear automatically in predefined folders such as Smartphone Photos, Timeline Photos, and Profile Pictures. As with photos in your handcrafted folders, these display the non-useful camera data, followed by any comments. Any post that went along with the photo doesn"t appear, nor is there any indication of a date, unless in the comments.


For a few photos, Facebook provides a link titled Facial Recognition Data. Clicking the liên kết brings up a mix of incomprehensible numbers and raw data. The fact that all of these were photos of Halloween pumpkins doesn"t inspire confidence.

In my view, Facebook could handle this a lot better. Suppress the camera data except when requested. Include the date for any photo lớn. And when I snap a photo lớn và post it, include the text of the post with the phokhổng lồ.

Small-Screen Video

Clicking Videos, as expected, gets a list of all the videos you"ve sầu posted, from newest lớn oldest, with a 284 by 160 px thumbnail. You also get the video"s date & time, and any comments. When I clicked on a video clip, though, I got a surprise.

The Facebook archive sầu stores videos as 400 by 224 MP4 files; it doesn"t link to lớn the full-form size video that you posted. When I launched one of those, I found that the sound worked fine, but the video itself just showed shifting bands of color. I tried a half-dozen videos, and the same thing happened with all of them.

That was under Firefox. When I opened the same page in Chrome or Edge, the Clip played bachồng just fine. Internet Explorer didn"t try internal playback, but instead suggested opening the đoạn phim in the Movies và TV app. Movie và TV blew the video up to full screen, making it blurry, but it worked. I"m not sure what the problem is with Firefox, but there are plenty of other browsers for viewing your archive.


What if your real urge is lớn find the full-scale original video clip that you uploaded? You can"t get there directly from the archive sầu, but it can be a help. Cheông xã the date under the desired video clip, then open the list of videos right in your Facebook account online. Make a guess as to how far you should scroll down. Click a đoạn phim & check the date in the post that appears. Scroll up or down as necessary lớn bracket the desired date. It"s not igiảm giá khuyến mãi, but also not too difficult.

Ads và More Ads

Facebook exists to tempt you & other users with ads. Every time you cliông chồng an ad, that"s another data point for your profile. The first thing you see when you cliông xã the Ads liên kết is a danh sách of all the topics Facebook thinks interest you. In my case, the các mục runs to more than five sầu dozen items. Some make sense: coffee, California, computer security, network security, journalism, Alejandro Jodorowsky. Others have me head-scratching, things like water, landkhung, watermelon, and Order of Interbeing (what?). But those are the topics that inform just what ads Facebook inflicts on my feed.

More interesting is the following section, Ads History. This is simply a danh mục of ads and sponsored posts you"ve sầu clicked on recently. I"m not sure of the time period; the oldest one in my feed is from about seven weeks ago. It could also be a fixed number of the most recent ad-clicks. In my archive the total number lists comes out at the suspiciously round number 100. Yes, I confess, I clicked 100 ads. To be fair, I avoid clicking unsupported "Sponsored posts," but I bởi vì sometimes cliông xã ads shared by friends.

At the very kết thúc, the archive lists "Advertisers with your liên hệ info," eight of them, in my case. I recognize most of them, though I"m not sure how they got my contact info, or what it means that they did. But a couple are completely unfamiliar. I"m very deliberately not Googling these, figuring that doing so might just give sầu The Watchers more information.
