Thematic Areas

Reproduction of National ID Card (CNI)

The reproduction of the National Citizen Identification Card (CNI), whether in digital or physical format, raises important data protection concerns. The CNI contains sensitive information that uniquely identifies each citizen, meaning its copying, use, and sharing must comply with current data protection laws.

Is photocopying or scanning the CNI allowed?

Reproduction of the CNI should only occur when strictly necessary and in compliance with data protection regulations. Public or private entities requesting a copy must justify the need for collection and ensure the information will only be used for its intended purpose, adhering to data minimization and security principles.

Can I send a copy of my CNI via email or social media?

Sending a copy of your CNI via email, social media, or other digital platforms should be avoided, as it may expose your personal data to unauthorized access and potential fraud. Whenever necessary, use secure transmission methods and, if possible, conceal non-essential information.

Can companies keep copies of my CNI?

Businesses or organizations retaining copies of your CNI must comply with data protection principles. You have the right to know:
● The purpose of the copy
● How long it will be stored
● How it will be secured against unauthorized access

What should I do if my CNI copy is misused?

If you suspect your data has been misused, you may file a complaint with the National Data Protection Commission (CNPD). Stay vigilant against fraud attempts and protect your documents from unauthorized access.

Neighbor Video Surveillance

The installation of video surveillance cameras in private spaces, such as homes, buildings or condominiums, must comply with personal data protection legislation, especially when the images captured may cover public spaces or common areas shared with neighbours

Is it permitted to install video surveillance cameras in private homes?

Yes, owners may install video surveillance cameras in their homes for their own security. However, the capture of images must be limited exclusively to the owner's private space and may not cover public areas (such as streets, pavements or roads) or common areas of condominiums without proper consent.

Can I film my backyard and the entrance to my house?

Yes, as long as the images are captured only within your property. If the cameras capture outdoor areas shared with neighbours, such as corridors, stairways, lifts or communal garages, you must obtain the consent of the other residents or the condominium.

What if my camera captures part of the public road or my neighbours' property?

Capturing images of public spaces or third-party property without authorisation may constitute a violation of data protection legislation. Cameras must be adjusted to avoid framing areas outside the owner's private property.

Can neighbours install cameras pointing at my house?

No. Installing cameras aimed at neighbouring properties without consent is a violation of the owner's privacy and data protection rights. If you suspect that you are being filmed without authorisation, you can report the situation to the CNPD

What to do in case of misuse of video surveillance?

If you believe that your privacy is being violated due to the installation of video surveillance cameras by neighbours, you can file a complaint with the National Data Protection Commission (CNPD). If in doubt, the CNPD can provide guidance on how to ensure that the use of video surveillance complies with current legislation.
