Retail Analytics: How to Balance Security and Privacy in the AI Era

October 5, 2023

The retail industry is experiencing a profound technological revolution, with artificial intelligence (AI) and machine learning transforming the landscape. These new technologies bring immense benefits to expedite operations and enhance security, but they also raise concerns about customer privacy.

As AI expands into new industries, including retail analytics, regulators are increasingly focusing on data privacy issues. The European Union, for instance, has taken significant steps with the AI Act, categorizing AI systems according to the risks they pose and appropriately regulating them. Based on a report by Gartner, by 2024, 40% of privacy compliance technology will rely on AI, up from 5% in 2019, and by 2025, 60% of large organizations will use at least one privacy-enhancing computation technique in analytics, business intelligence, or cloud computing.

Benefits and Risks of AI for Retail Security

AI is revolutionizing how retailers approach security. By moving from reactive measures to proactive ones, businesses can better anticipate and manage risks. However, this transformation also draws greater attention to user privacy and data handling. While AI offers numerous benefits for retail security, it pose critical challenges concerning user privacy.

Some of the benefits are:

  • Detects and prevents fraud, theft, and cyberattacks by analyzing large amounts of data and identifying anomalies, patterns, and threats.
  • Improve customer experience and loyalty by providing personalized recommendations, offers, and services based on customer data and preferences.
  • Optimize inventory management and supply chain by forecasting demand, reducing waste, and enhancing efficiency.
  • Reduce costs and increase productivity by automating repetitive tasks, improving quality control, and enhancing decision-making.
  • Innovate and create new products and services by leveraging data insights, customer feedback, and market trends.

Some of the risks are:

  • Ethical and legal challenges, such as ensuring data privacy, avoiding bias and discrimination, and complying with regulations.
  • Create security vulnerabilities for retailers, such as exposing sensitive data to hackers, malicious actors, or competitors.
  • Disrupt the retail workforce by replacing human workers, creating skill gaps, and requiring new training and education.
  • Increase the complexity and uncertainty for retailers, such as dealing with technical glitches, errors, or failures.
  • Affect the trust and reputation of retailers, such as losing customer confidence, facing public backlash, or facing legal actions.

According to a survey by Taylor Wessing, 69% of consumers said they are concerned about how their personal data is used by companies, and 58% said they are more likely to trust companies that are transparent about their data practices. Therefore, retailers need to consider and balance the benefits and risks of AI for retail security and privacy and adopt a consumer-centric approach to data collection and use.

Data Breaches Threaten Retail Analytics: Real Cases

Costco: In October 2023, the wholesale retailer notified its customers that it experienced a data breach that exposed the personal information of some online shoppers, including names, email addresses, shipping addresses, order details, and Costco membership numbers. The breach occurred due to a third-party vendor that provided chat services on the company’s website.

American Airlines: In June 2023, the airline company reported that it suffered a data breach that exposed the personal information of thousands of pilots who applied for jobs at American Airlines and Southwest Airlines. The breach occurred due to a hacker who accessed a database maintained by a recruiting company that worked with both airlines.

UPS Canada: In July 2023, the delivery company confirmed that it experienced a data breach that exposed the personal information of some customers in Canada, including names, phone numbers, and addresses. The breach occurred due to a misuse of a package tracking tool on the company’s website.


Cybercriminals can exploit customer data from retailers and brands for illicit gains on the dark web or identity and fraud schemes. Retailers and brands must adopt robust security practices to safeguard their customer data and adhere to global rules such as GDPR and CCPA.

How to Achieve the Right Balance between Security and Privacy?

Finding the right balance between increased security and customer privacy requires both technical and non-technical solutions. Here are some best practices that can help retailers achieve this balance:

  • Use AI technologies that protect privacy. For example, tokenization can replace sensitive data with non-sensitive tokens that can be used for analysis without compromising privacy. Encryption can also protect data from unauthorized access or tampering.
  • Audit data and systems regularly. This can help identify potential vulnerabilities, gaps, or violations and take corrective actions accordingly.
  • Be transparent about data processing. Inform customers about what data is collected, why it is collected, how it is used, who it is shared with, and how long it is stored. Provide customers with clear and easy options to opt-in or opt-out of data collection or use.
  • Foster a collaborative culture within the organization. Ensure that all stakeholders involved in retail security have the necessary skills, mindset, and training to handle the complex balance between harnessing AI and safeguarding customer privacy. Encourage communication and feedback among different teams and departments.

Final Thoughts

AI and data privacy are inextricably linked in retail, offering both opportunities and challenges. While AI enhances security, operations, and customer experience, it also raises ethical, legal, and technical concerns. Striking the right balance and adopting a consumer-centric approach is crucial. By following the best practices, retailers can leverage AI for security while safeguarding privacy.

Still, data breaches remain a serious threat, as recent incidents at Costco and American Airlines demonstrated. Protecting customer data and complying with regulations is imperative.
