If data is gold, then that gold must be protected. In software development, data is often thought to be unbiased, purely mathematical, and have no reason to engage with ethics. However, I want to posit that not just protecting one’s data but centering it’s ethical use is paramount to every software developer’s role, and further, every person’s role in a tech company. We will offer a deep dive into ethical data stewardship, while presenting comprehensive frameworks, guidelines, and a step-by-step walkthrough of an ethical technical sprint designed to integrate these principles into your software development practices.

Understanding Ethical Stewardship in Software Development

Ethical data stewardship is defined by the Open Data Institute, as “an iterative, systemic process of ensuring that data is collected, used and shared for public benefit, mitigating the ways that data can produce harm and addressing how it can redress structural inequities.” This understanding and approach is crucial in preventing data misuse and maintaining public trust, particularly as data-driven technologies increasingly affect every aspect of our lives.

Core Frameworks for Ethical Decision-Making

As software engineers and tech professionals, we often do not engage with ethics in our everyday software development practices. However, there are several ethical frameworks we can incorporate into our daily lives to help fellow developers navigate complex ethical landscapes surrounding data:

    1. IEEE’s Ethically Aligned Design:
      • Principles: Focuses on human rights protection, prioritizing user well-being, and ensuring system accountability.
      • Application: Consider an AI-driven healthcare application where the IEEE principles guide the development to ensure algorithms provide equitable health advice without discriminating based on inherent biases.
    2. Menlo Report:
      • Principles: Emphasizes respect for individuals, beneficence, justice, and respect for law and public interest.
      • Application: Useful for mobile apps that gather user location data, applying Menlo principles would involve ensuring that the data collection is transparent, benefits the users, and distributes data benefits fairly without exploiting specific groups.

Tools and Technologies to Enhance Ethical Practices

Developers have various technologies at their disposal to facilitate ethical data handling:

    • Homomorphic Encryption:
      • Detail: Allows data to be encrypted and processed simultaneously, enabling secure data analysis without exposure.
      • Use Case: In financial services, homomorphic encryption can be used to analyze personal investment data, providing personalized advice without compromising client confidentiality.
    • Differential Privacy:
      • Detail: Adds mathematical noise to datasets or queries, ensuring individual privacy while maintaining the utility of aggregate data.
      • Use Case: When analyzing user behavior data for a marketing study, differential privacy ensures that the insights gained do not allow any individual user’s data to be distinguished.
    • Data Ethics Checklist:
      • Detail: A comprehensive checklist that ensures all aspects of data handling, from collection to analysis, meet ethical standards.
      • Implementation: Before deploying a new user tracking feature, developers can use the checklist to review the ethical implications, ensuring that user consent is obtained and data minimization principles are followed.

Detailed walkthrough of an Ethical Sprint: data anonymization in a sample “HealthTrack” App

Let’s take a look at an example app project to explore how we can apply advanced data anonymization techniques. Our goal is to protect user privacy while keeping the app’s personalized health insights effective and functional.

Objective: Implement state-of-the-art data anonymization techniques in HealthTrack, an app that uses personal health data to provide tailored health insights.

Planning Phase

    • Team Composition: Assemble a multidisciplinary team, including a project manager to oversee the sprint, a backend developer skilled in data security, a frontend developer, and a data privacy expert.
    • Sprint Goals: Establish clear objectives to integrate robust anonymization protocols that protect user privacy without undermining the app’s functionality.

Implementation and Testing Phase

    • Days 1-2: Develop anonymization protocols.
      • Differential Privacy: The backend team integrates algorithms to inject statistical noise into datasets, ensuring that outputs do not compromise individual privacy.
      • Pseudonymization Techniques: Implement processes to replace direct identifiers with pseudonyms systematically, adding an additional layer of security.
    • Day 3: Prototype testing and user feedback.
      • User Experience Trials: Conduct focused group testing to gather feedback on how anonymization impacts user experience and the personalization of health insights.
      • Feedback Review: Analyze feedback to identify any potential trade-offs between anonymization strength and functionality.

Review and Iteration Phase

    • Day 4: Stakeholder reviews and ethical evaluations.
      • Broad Review: Present anonymization strategies to a broader stakeholder group, including potential users and internal compliance teams, to ensure all ethical and operational standards are met.
      • Ethical Impact Assessment: Conduct a comprehensive review to ensure all implementations align with the Menlo Report and IEEE principles.
    • Day 5: Final adjustments and documentation.
      • Refinements: Make necessary adjustments to the anonymization techniques based on stakeholder feedback.
      • Documentation and Reporting: Document the methodologies, decision-making processes, and justifications for the chosen strategies to ensure transparency and accountability.

Promoting an Ethical Culture

Creating a sustainable ethical culture involves more than periodic checks:

    • Regular Ethical Training: Implement ongoing educational programs that keep the team current on ethical issues and emerging technologies.
    • Daily Ethical Practices: Embed ethical discussions into daily routines, such as stand-ups and code reviews, to maintain a continuous focus on ethical decision-making.


Ethical data stewardship is a crucial aspect of software development that demands both attention and action. By embracing the frameworks, tools, and practices outlined above, engineers and tech professionals can ensure that their features and products not only push technological boundaries but also promote fairness, privacy, and trustworthiness in every aspect of the software development process.
