One of the key concerns surrounding electronic voting is personal data protection, especially as digital platforms handle sensitive voter information.
Electronic (eVoting) and online (iVoting) voting are among the most exciting technological innovations in participatory democracy in recent years. Through the use of advanced computer systems, it is possible to cast one’s vote electronically, with all the advantages that come with it in terms of convenience, speed, and security.

However, the adoption of this technology requires caution especially on the protection of voters’ personal data. In this article, we will explore the General Data Protection Regulation (GDPR) rules in relation to electronic voting, and see what measures need to be taken to ensure adequate privacy protection.
How personal data protection shapes secure electronic voting
Personal data protection plays a central role in the design and operation of secure electronic voting systems. From voter registration to ballot submission, each phase of the process must safeguard sensitive information against unauthorized access or misuse.
Ensuring compliance with data protection regulations—such as GDPR, CCPA, or LGPD—requires voting platforms to implement encryption, access controls, and data minimization principles. By embedding privacy by design into the voting infrastructure, organizations not only meet legal obligations but also build trust with voters, reinforcing the integrity and transparency of the entire election process.
What is GDPR?
The GDPR is the European Data Protection Regulation that came into force on May 25, 2018, replacing the previous European Directive of 1995. Its main objective is to ensure a high level of protection for the fundamental rights and freedoms of individuals, particularly with regard to the processing of personal data. The GDPR applies to all organizations that process personal data, regardless of whether they are public or private, large or small. This means that any organization that collects, uses or stores personal data of individuals within the European Union must comply with the GDPR.
Electronic voting and data processing
In the case of digital voting, the processing of personal data takes on special importance. The information collected during the voting process may include sensitive voter data. For this reason, the GDPR establishes a set of rules and principles to be followed to ensure proper handling of personal data in the context of digital voting.
Transparency
One of the fundamental principles of the GDPR is that of transparency. Organizations that process personal data must adequately inform data subjects about how their personal data are collected, processed, and stored, as well as the security systems in place to prevent possible privacy breaches.
Data minimization
Another important principle of the GDPR is that of data minimization. Organizations that process personal data must collect only the information necessary to fulfill their purpose, and they must limit the amount of data processed to the bare minimum. In the case of digital voting, this means that only the data necessary to ensure voter identification should be collected, without overdoing it with superfluous or irrelevant information.
Security of personal data
Personal data protection under the GDPR requires that appropriate technical and organizational measures be taken to ensure the security of personal data. In the case of telematics voting, this means that secure and reliable computer systems must be used that are capable of preventing any cyber attacks or unauthorized intrusions. In addition, organizations must adopt procedures for backing up and restoring data in the event of technical problems or system malfunctions.
Finally, the GDPR provides for the right of data subjects to access their personal data, to request its rectification or erasure, and to object to its processing in certain cases. To ensure the effective application of GDPR rules in the context of digital voting, the privacy guarantors of EU member states have issued specific guidelines.
What about outside Europe?
While the GDPR is the most recognized data protection framework globally, many countries have introduced their own privacy regulations that impact how electronic voting systems must handle personal data.
In the United States, the California Consumer Privacy Act (CCPA) sets strong requirements for transparency, data access, and consumer control, which influence how platforms manage voter data. In Brazil, the Lei Geral de Proteção de Dados (LGPD) mirrors many GDPR principles, requiring clear consent, purpose limitation, and secure data handling practices. Canada’s PIPEDA (Personal Information Protection and Electronic Documents Act) also places emphasis on informed consent and accountability, particularly in the private sector.
Across these jurisdictions, the common thread is the need for privacy by design, meaning that electronic voting platforms must integrate data protection at every stage—from voter identification to encrypted vote storage and result reporting. For multinational organizations, this means choosing voting technologies that comply with multiple privacy laws simultaneously, ensuring secure and inclusive elections across borders.
Choosing a voting platform with strong personal data protection features is crucial for ensuring trust and legal compliance.
