For more than 20 years, the main mechanism for gathering data by digital marketing has been third-party cookies. Those small files enabled advertising companies to construct complete information about particular people based on their activities and preferences.
Nevertheless, because of growing concerns regarding digital spying and stringent laws, tech companies had to find a way out of using such a tracking system.
In order to combine the needs for preserving users’ confidentiality and digital advertising, Google has developed a new set of web standards called the privacy sandbox.
In order to better comprehend the concept of browser protection, one should picture themselves as a local guide rather than an investigator. While third-party cookies could be compared with people being tracked by investigators from one platform to another, the browser acts as a shield that protects the users.
The privacy sandbox is an umbrella project that includes various tools and APIs installed in the browser. Rather than sending all the gathered information to advertising servers, it keeps personal records on the user’s own physical device.
Substitution of intrusive cross-site tracking is based on the use of several different APIs tailored for particular advertisement-related objectives:
The functionality involves classification of browsing patterns in terms of broad interest categories (e.g., “Fitness” or “Travel”) during some recent period. Advertisers make requests regarding such generalized topics to deliver suitable advertisements while not being able to get access to actual browsing histories.
This is the tool used for retargeting that conducts ad auctions on the user’s computer to prevent third parties from tracking user activity on independent sites.
The system evaluates the performance of advertisements and conversion rate based on the data collection of conversion metrics anonymously.
Although localizing the processing of information makes everything more secure, there are also some industry considerations for operating in today’s privacy sandbox world:
Advertising is crucial for sustaining all kinds of free online services. The development of the privacy sandbox framework is one of the biggest steps in the replacement of tracking technology with privacy standards.
Through the aggregation of user interests at the level of browser architecture, businesses can thrive without compromising privacy.
