Google's proposal of engagement as a user gesture has significant implications for the understanding of privacy and the ability to predict functionality availability in the context of web fingerprinting and privacy on the web. This proposal introduces a new approach to user engagement and interaction with web applications, which can have both positive and negative consequences.
Firstly, let us explore the impact on privacy implications. Web fingerprinting refers to the process of collecting and analyzing various attributes of a user's web browser and device to create a unique identifier or "fingerprint." This fingerprint can then be used to track and identify users across different websites and online activities. Traditionally, web fingerprinting techniques have relied on passive data collection, such as analyzing browser headers, user agent strings, and installed plugins.
However, Google's proposal introduces the concept of active user engagement as a gesture to enhance privacy. Instead of passively collecting data, web applications would require explicit user actions or gestures to access certain functionalities or collect specific information. For example, a web application might prompt the user to grant permission for location access or microphone usage only when the user actively interacts with a relevant feature, such as a map or voice search.
This approach has the potential to provide users with more control over their privacy by requiring their explicit consent for data collection. By making user engagement a prerequisite for data collection, it becomes more difficult for websites to passively collect information without the user's knowledge or consent. This can help mitigate some of the privacy concerns associated with web fingerprinting techniques.
On the other hand, this proposal also presents challenges in predicting functionality availability. With the introduction of user engagement as a requirement, the availability of certain functionalities becomes contingent upon the user's actions. This means that the behavior and functionality of web applications can vary depending on the user's level of engagement.
For example, a web application might offer additional features or personalized content only when the user actively engages with the site, such as by clicking on specific elements or providing explicit feedback. This introduces a level of unpredictability in terms of what functionalities are available to the user at any given time.
Moreover, the ability to predict functionality availability becomes more challenging for web developers and security analysts. Traditional methods of analyzing web applications and their behavior may no longer suffice, as the availability of certain features is tied to user engagement. This necessitates a more dynamic and adaptive approach to understanding and predicting the behavior of web applications.
Google's proposal of engagement as a user gesture brings both privacy benefits and challenges in terms of predicting functionality availability. By requiring explicit user engagement, this approach can enhance user privacy by providing more control over data collection. However, it also introduces unpredictability in terms of what functionalities are available to the user, posing challenges for web developers and security analysts.
