Thank you, Kevin.
Thank you to the committee for having me here today.
As Kevin mentioned, I'm Facebook's deputy chief privacy officer. I want to apologize for not being able to join today's committee hearing in person. I'm hosting a summit today in California with many leading privacy experts, a summit that had been scheduled for some time. I appreciate the committee's attention to this important matter, and we appreciate the opportunity to provide information to support your study.
I'd like to spend just a few minutes on the specifics of this situation and what we're planning to do going forward.
In 2015 we learned from a report in The Guardian that a Cambridge University researcher named Aleksandr Kogan had shared data from a quiz app that he operated on the Facebook platform, This Is Your Digital Life, with Cambridge Analytica. It is against our policies for developers to share data without people's consent, so we immediately banned Dr. Kogan's app from our platform and demanded that Dr. Kogan and certain other entities he had relationships with, including Cambridge Analytica, delete any information they had received.
Several weeks ago we saw press reports alleging that some of this information may not have been deleted as Dr. Kogan, Cambridge Analytica, and others had certified. Based on our own data, we estimated a total of 305,000 people around the world had installed the app This Is Your Digital Life and that an additional 86.3 million were friends of people who had installed that app and were therefore potentially affected by data sharing.
While the vast majority of these people were in the United States, we estimate that 272 people in Canada installed the app, potentially affecting 621,889 additional Canadians. This represents 0.7% of the people affected across the world.
We take each case with the utmost seriousness, and that is why we're informing people if there is even a possibility that they may have been affected.
We have a responsibility to make sure that what happened with Cambridge Analytica does not happen again, so we've undertaken a series of steps to increase the protections we're providing for people's information. Here are some of the steps.
First, we need to make sure that developers like Dr. Kogan who got access to a lot of information in the past cannot get access to as much information anymore. We already made changes to the Facebook platform in 2014 to dramatically restrict the amount of data that app developers can receive and to proactively review apps before they can use our platform. Because of these 2014 changes, a developer today would not have access to the same amount of data that Dr. Kogan was able to obtain.
However, there is more that we intend to do to limit the information developers can access and to put more safeguards in place to prevent abuse. For instance, we're removing developers' access to your data if you haven't used their app in three months. We're reducing the data you give an app, when you use the new version of Facebook login, to only your name, your profile photo, and your email address. That's a lot less than is available to developers on any other major app platform. If a developer wants to use Facebook login to obtain more information than this—for example, access people's posts or other private data—we'll require them to sign a separate contract with us that imposes strict requirements.
Second, we're in the process of investigating every app that had access to a large amount of data before we locked down our platform in 2014. If we detect suspicious activity, we'll do a full forensic audit. If we find that someone is improperly using data, we'll ban them and we'll tell everyone affected.
Finally, we're making it easier to understand to which apps you've allowed access to your data. This past week we started showing everyone a list of the apps they've used and then an easy way to revoke permissions they've granted to those apps in the past. This is something you can already do in your privacy settings, but we're putting it at the top of the news feed to be sure everyone sees it.
We've also announced proposed updates to our data policy and terms of service to provide more information about our data practices and the choices people have. We hope this will better enable people to make informed decisions about their privacy and to better understand how we use data across Facebook, Instagram, Messenger, and our other services.
I'd now like to turn it back to my colleague Kevin to talk a bit about what we are doing with respect to election integrity in Canada.
