What the FLoC, Google? How Google is Developing New and Exciting Ways To Track You

Tracking cookies are on the decline, partly because many browsers now block third-party cookies by default. In response, Google is developing a new way to track users called Federated Learning of Cohorts (FLoC). Instead of using cookies, Google is building FLoC tracking capabilities into the Chrome browser itself and is already trying it out on about 0.5% of its users.

FLoC effectively works by lumping groups of users Google considers similar into buckets called “Cohorts”. Then advertisers can target these groups with ads. Google claims this protects privacy because individual users in the cohort remain anonymous; however, the EFF (Electronic Frontier Foundation), Mozilla, Brave, and many other companies aren’t buying it, citing several issues with Google’s privacy claims (https://www.eff.org/deeplinks/2021/03/googles-floc-terrible-idea).

The question we should be asking is “How can we stop companies tracking users on the Internet?” not “How can we come up with new ways to track people?”.

Apple Introduces AirTags

Apple recently released a new product called AirTags, which allows users to track the physical location of just about anything. AirTags are small, disc-shaped devices and can be attached to keys, backpacks, laptops, and anything else you don’t want to lose. They use Bluetooth in coordination with everyone on the planets’ iPhones to keep track of where they go. This is an extremely powerful technology and is a great way to keep track of things you don’t want to lose, considering the supporting network of more than 1 billion people who use iPhones.

Naturally, there are several privacy concerns, like 1) using other people’s iPhones to constantly report the location of other AirTags locations and 2) how a stalker or abuser might use an AirTag to track a victim’s location.

The first problem is addressed by using encrypted data and rotating keys so that theoretically, not even Apple could track your AirTags location. The second problem is addressed by features Apple has included to prevent stalking, including alerting victim’s if an AirTag is planted on them.

The jury is still out on how secure these devices are. There have already been some reports of the “stalker” feature taking multiple days to kick in.

Coinbase Went Public

The popular cryptocurrency company, Coinbase, went public this past month, trading at $381 per share. Coinbase allows users to buy, trade, and sell various cryptocurrencies. One of its main selling points is its ease of use which is a sticking point for many exchanges.

Such a large crypto exchange going public brings more attention and legitimacy to cryptocurrency holding and trading.
