Data protection when using AI: recommendations for using ChatGPT safely

Artificial intelligence has transformed the way we work, communicate and make decisions. Tools such as ChatGPT have become key allies for businesses and professionals, simplifying tasks and streamlining processes. However, their use raises a fundamental question: how can we ensure data protection and regulatory compliance in an environment where information is constantly flowing?

To understand the risks and adopt best practice, it is essential to know how ChatGPT handles user data, which regulations govern it, and what measures can be put in place to minimise vulnerabilities.

Data processing in ChatGPT and its implications for privacy

When we interact with ChatGPT, it is important to know what sort of data it collects and how it is used. OpenAI has set out different policies depending on the type of account used. In the free and standard paid versions, conversations may be stored and analysed for the purpose of improving the model, although this option can be disabled in the Data Controls. In contrast, accounts aimed at businesses, such as ChatGPT Teams or Enterprise, ensure that the data entered is not used to train the model, thereby offering a higher level of security and confidentiality.

User data is stored on OpenAI’s servers located in the United States. Although the company has implemented security measures, the fact that the information is hosted outside the European Union may raise concerns about its level of protection compared with the standards required by the GDPR. Although OpenAI does not sell the information to third parties or use it for marketing purposes, there remains a risk that the data could be exposed in the event of vulnerabilities or unauthorised access.

Bearing these factors in mind, it is essential to adopt a proactive and responsible approach when using ChatGPT, avoiding the sharing of confidential information or personal data that could compromise users’ privacy or a company’s security.

The regulatory framework: the GDPR and the new Artificial Intelligence Act

In Europe, the use of AI tools such as ChatGPT is primarily regulated by the General Data Protection Regulation (GDPR), which sets out key principles such as data minimisation, transparency and user control over their information. Furthermore, in Spain, the Organic Law on Data Protection and the Guarantee of Digital Rights (LOPDGDD) supplements this legislation with additional requirements.

One of the most controversial issues has been the lack of transparency in some AI models regarding the processing of personal data. Although OpenAI has improved its policies, the GDPR requires companies to provide clear and accessible information on how user data is managed. In this regard, one of the remaining challenges is ensuring that ChatGPT’s privacy documentation is available in the user’s language, as it is currently mostly in English.

The regulation of AI in Europe has taken a decisive step forward with the adoption of the Artificial Intelligence Regulation (AI Act). This new legislation establishes a legal framework for the development and use of AI, classifying systems according to their level of risk and requiring greater safeguards regarding transparency, explainability and human oversight, particularly in cases where fundamental rights may be affected. Its implementation marks a turning point in the governance of artificial intelligence in Europe, ensuring that its use is safe, ethical and compatible with the principles of the GDPR.

Best practice for the safe use of ChatGPT

To reap the benefits of artificial intelligence without compromising data security, it is essential to put a number of preventative measures in place. One of the first steps that can be taken is to disable the saving of conversation history in the settings for Data Controls, thereby preventing OpenAI from using the data entered to train the model. This option is particularly recommended for those who handle sensitive information in professional settings.

It is also essential to avoid sharing personal or confidential information when interacting with AI. Details such as official identification documents, addresses, telephone numbers, passwords or financial information should never be entered into a conversation with ChatGPT. In a business context, it is also important to restrict the use of AI when processing strategic data, contracts, internal documents or any information that could compromise corporate security.

As well as limiting the type of information shared, it is advisable to enable multi-factor authentication (MFA) on your OpenAI account to prevent unauthorised access. If you use ChatGPT on shared devices, you should log out after each use to prevent third parties from accessing your conversations.

Another key practice is to manually delete chats if you have accidentally entered sensitive information. Although OpenAI states that stored data is automatically deleted after 30 days, manual deletion further reduces the risk of exposure.

The future of AI and privacy: an evolving relationship

As artificial intelligence continues to evolve, the regulations governing its use are becoming increasingly stringent. With the AI Act coming into force, companies that develop and use AI will have to comply with stricter requirements regarding transparency, security and user rights.

Beyond regulatory requirements, companies are beginning to adopt the “Privacy by Design” approach, integrating privacy as a fundamental principle in the development of new technologies. In this context, artificial intelligence must not only comply with current legislation, but must also build trust among users by ensuring that data is used in an ethical, secure and responsible manner.

Conclusion: using ChatGPT safely and responsibly

The use of ChatGPT and other artificial intelligence tools offers enormous benefits, but it is essential to use them responsibly and safely. Adopting best practices, keeping up to date with the regulatory framework and using the appropriate privacy settings are essential steps for protecting data and ensuring legal compliance.

By implementing these strategies, you will not only make the most of AI’s capabilities, but you will also contribute to a safer and more ethical digital environment.
