Designing Tomorrow User Experience

In the realm where a significant amount of personal data is processed online, the importance of Privacy in User Experience (UX) design cannot be overstated. As technology evolves and digital interactions become more integrated in our daily lives, users are increasingly demanding transparency, control, and security over their personal data. Therefore, it is imperative for businesses to prioritize privacy-centric design principles to not only meet regulatory compliance requirements but also to cultivate trust and loyalty among their customers.

Introducing the Privacy Experience (PX) concept

In this article, I introduce the innovative “Privacy Experience (PX)” concept, which seamlessly combines data privacy and UX design. In privacy-centric design, the “user” comes first, and it should be empowered with transparent information about data collection practices and provided with granular control over their personal data. By prioritizing user privacy and offering clear choices, UX designers can foster trust and enhance the overall user experience while still meeting business objectives.

The following key PX best practices should be considered when designing websites and applications collecting personal data:

• Collect only a minimum amount of personal data. It is important to request the minimum amount of personal data to fulfill the defined purpose of processing. For example, for subscribing for updates on the website, only the user's email address should be sufficient for this purpose (see picture); for ordering delivery services only first and last name, delivery address and phone number will be enough to deliver the product to the customer.

• Empower users to make informed decisions regarding the sharing of their personal data with a service. Users must be provided with sufficient details about a service and its usage of their personal data to make decisions regarding whether to share their personal data or not. Usually, it can be achieved by providing a Privacy Notice to users stating a list of personal data collected, purposes and lawful basis for personal data processing, retention periods, third parties with whom personal data will be shared including cross border data transfers, data subjects’ rights, security measures, etc. It is imperative to implement just-in-time notices, concise yet transparent, to provide users with small portions of essential information throughout their journey.

• Ensure that consent to personal data processing is freely given, specific to the data collected, and based on informed decision-making. Service must offer users the freedom to withdraw consent, and provide adequate information about its intended use at the time of data collection. Statement such as “By using this website you are agreeing to our Privacy Policy” is not considered as a proper consent anymore. In practice, every form where personal data is collected, should require a clear action from the user, for example, include an opt out check box with a text “I agree to the processing of personal data” and link to the Privacy Notice (see picture). Keep in mind to collect explicit consent for direct-marketing purposes.
• Implement controls around sharing of personal data with third parties. Companies should offer granular privacy settings that allow users to adjust their preferences and permissions. Setting up controls for sharing personal data with third parties gives users the power to choose who can access their personal data beyond the website/application. With simple privacy settings, users can decide who gets their data, building customers’ trust.

• Provide users an opportunity to exercise their rights. Website may collect and retain users’ personal data to enhance its functionality, such as storing credit card details or billing addresses. However, it’s essential for the service to transparently inform users about the specific information being retained and its intended use. Additionally, users should be provided with options to correct or delete their information if needed. In practice, it can be implemented as a list of data subjects’ rights where the user can choose a right which he/she wants to exercise, and fill out a form with the necessary information (see picture).
• Ensure confidentiality, integrity and availability of personal data. It is key to incorporate security features such as end-to-end encryption, multi-factor authentication, and robust data protection measures to protect personal data against unauthorized access or data breaches. Encrypt personal data stored on the device using strong encryption algorithms (e.g. AES 256). Use TLS/SSL with strong cipher suites for data transmitted over the network. Securely manage encryption keys, avoiding hard-coded keys within the application code. Ensure that all API calls are authenticated and data is validated server-side. Validate all user inputs to prevent common vulnerabilities such as SQL injection, cross-site scripting (XSS), and other injection attacks.

Privacy-centric design does not mean sacrificing personalization. By leveraging techniques like pseudonymization, anonymization, businesses can deliver personalized experiences tailored to individual preferences without compromising user privacy.

Ultimately, the end user will use the website/application, and the service should have built-in features (e.g., using the artificial intelligence) to protect this user from disabling technical security mechanisms based on an analysis of the non-standard behavior of this user (for example, under the influence of social engineering).

Final thoughts

In the digital age, privacy is not just a feature but a fundamental right that users expect. UX designers must continually iterate and improve privacy features based on user feedback, emerging technologies, and evolving regulatory landscapes to ensure that privacy remains at the forefront of the user experience.
