The management of sensitive data in elections is one of the most relevant challenges for organizations, professional associations, universities, and public entities that organize digital electoral processes.
Elections inevitably involve the processing of personal data in voting, and in many cases also what the GDPR defines as special categories of data, such as political opinions, trade union membership, or belonging to certain organizations.
If the identity of the voter could be linked to their choice, the integrity of the electoral process would be compromised.
What the GDPR considers sensitive data in elections
Sensitive data in elections is not limited to the basic information of a voter. In reality, electoral processes involve the processing of different types of personal data that, in certain contexts, may reveal intimate aspects of a person’s identity, opinions, or affiliations, and this completely changes the level of protection required by law.
The General Data Protection Regulation (GDPR) defines personal data as any information relating to an identified or identifiable natural person. This includes obvious elements such as a name or identification number, as well as less obvious ones such as IP addresses, access credentials, or digital identifiers used during an online vote.
In Article 9, an even more sensitive concept is introduced, the special categories of personal data, which include information that, by its nature, requires a reinforced level of protection. These include political opinions, trade union membership, religious or philosophical beliefs, ethnic or racial origin, data concerning health, sexual orientation, among others.
A digital voting system must guarantee that the vote cast cannot reveal any of these sensitive data in elections.
GDPR principles applied to the handling of electoral data
The GDPR establishes a series of fundamental principles that must be respected in any processing of personal data.
| GDPR principle | Application in electoral processes | Main objective |
| Lawfulness and purpose limitation | Data is used exclusively to organize and validate the vote | Prevent misuse of information |
| Data minimization | Only the information strictly necessary to identify the voter is collected | Reduce the risk of data exposure |
| Storage limitation | Data is deleted or anonymized once the electoral process has ended | Avoid unnecessary storage |
| Integrity and confidentiality | Use of encryption, access control, and system auditing | Protect sensitive data in elections |
Modern electronic voting platforms such as Eligo apply multiple layers of security to protect this data, and to prevent any possibility of linking voter identity with the electoral decision.
Eligo facilitates GDPR compliance in electoral processes
The GDPR introduces principles such as privacy by design and privacy by default, which require data protection to be incorporated directly into the architecture of digital systems. Therefore, properly managing sensitive data in elections is not only a legal matter, but also a technological responsibility.
Eligo integrates security and privacy mechanisms adapted to the electoral context from its design stage. This includes features such as secure voter authentication, separation between identity and vote, management of the electoral register, and role based access control. All security controls are automated, helping organizations comply with the principles of security, integrity, and confidentiality established by the GDPR.
A significant example of this technological application can be found in the case of Enel, one of the largest energy companies in Europe. The company organized digital union elections for more than 29,000 employees, managing a complex electoral process that involved the processing of information related to trade union membership.
The digitalization of the process made it possible to simultaneously guarantee vote anonymity, identity verification, and the protection of participants’ personal data.
Conclusion, protecting sensitive data in elections is a strategic responsibility
Organizations that organize electoral processes must adopt a responsible and structured approach. It is not enough to formally comply with the regulations. It is necessary to apply technological and organizational best practices that ensure the electoral process is secure from the very beginning.
If your organization organizes internal, union, university, or corporate elections and needs to manage sensitive data in elections in a secure, transparent, and GDPR compliant way, it may be the right time to explore specialized solutions.

5 FAQs about sensitive data in elections
What legal risks exist if an organization mishandles data in a digital vote?
It may face significant penalties. The GDPR provides for administrative fines that can reach up to 20 million euros or 4% of the organization’s global annual turnover. Beyond the legal impact, poor management of sensitive data in elections can seriously damage the organization’s reputation and create distrust among voters.
Who is responsible for data processing in an online electoral process?
The main responsibility lies with the organization that calls the vote, as it acts as the data controller under the GDPR. When external electronic voting platforms such as Eligo are used, they act as data processors and strictly follow the instructions established by the controller.
How can it be prevented that a system administrator sees how participants voted?
In many cases, the vote is encrypted before it is sent to the server and is only decrypted during the counting process. This ensures that even those who manage the platform cannot link the voter’s identity with their electoral choice.
Can voters exercise their data protection rights during an election?
Yes. Participants in an electoral process retain all the rights recognized by the GDPR, such as the right of access, rectification, or restriction of the processing of their personal data. The organization must clearly inform voters about these rights and how they can exercise them.
Is it mandatory to conduct a data protection impact assessment for digital elections?
In many cases, yes. When an electoral process involves the processing of special categories of data or the use of technologies that may significantly affect the rights of participants, the GDPR recommends carrying out a Data Protection Impact Assessment, DPIA.
