USPS Shared Customers Postal Addresses With Meta, LinkedIn and Snap
Thursday July 18, 2024. 09:21 PM , from Slashdot
An anonymous reader quotes a report from TechCrunch: The U.S. Postal Service was sharing the postal addresses of its online customers with advertising and tech giants Meta, LinkedIn and Snap, TechCrunch has found. On Wednesday, the USPS said it addressed the issue and stopped the practice, claiming that it was 'unaware' of it. TechCrunch found USPS was sharing customers' information by way of hidden data-collecting code (also known as tracking pixels) used across its website. Tech and advertising companies create this kind of code to collect information about the user -- such as which pages they visit -- every time a webpage containing the code loads in the customer's browser.
In the case of USPS, some of that collected data included the postal addresses of logged-in USPS Informed Delivery customers, who use the service to see photos of their incoming mail before it arrives. It's not clear how many individuals had their information collected or for how long. Informed Delivery had more than 62 million users (PDF) as of March 2024. The code also collected other data, such as information about the user's computer type and browser, which appeared as partly pseudonymized -- essentially scrambled in a way that makes it more difficult for humans to know where data came from, or who it relates to, by using randomized identifiers in place of real customer names. But researchers have long warned that pseudonymous data can still be used to re-identify seemingly anonymous individuals. TechCrunch also found that tracking numbers entered into the USPS website were also shared with advertisers and tech companies, including Bing, Google, LinkedIn, Pinterest and Snap. Some in-transit tracking data was also shared, such as the real-world location of the mail in the postal system, even if the customer was not logged in to USPS' website. USPS spokesperson Jim McKean said in a statement: 'The Postal Service leverages an analytics platform for our own internal purposes, so that we understand the usage of our products and services and which we use on an aggregated basis to market our products. The Postal Service does not sell or provide any personal information that is collected from this analytics platform to any third party, and we were unaware of any configuration of the platform that collected personal information from the URL and that shared it without our knowledge with social media.' 'We have taken immediate action to remediate this issue,' the spokesperson added, without saying what action was taken. Read more of this story at Slashdot.
