Public Interest Whistleblower Protection Act Article 16

Unless otherwise provided by law or if confidentiality of identity is no longer necessary, a whistleblower may request that their personal data be recorded in transcripts and documents using a code, with their name, gender, date of birth, residence, identification document serial number, or any other information that could directly or indirectly identify them concealed. If it is necessary to keep their signature confidential, they may use a fingerprint or sign with a code instead. A comparison table linking the codes and real names shall be prepared, sealed in an envelope, and attached to the file.Unless otherwise provided by law, the transcripts or documents referred to in the preceding paragraph may not be made available for viewing or provided to any agency (institution), legal person, group, or individual other than investigative or judicial authorities.When a whistleblower is questioned (interrogated) during an investigation or trial, they may, upon request, have their face concealed, voice or image altered, or participate via video conference or other appropriate isolation methods. The same applies when they are confronted or cross-examined in accordance with the law.The whistleblower may opt to forfeit the protection measures in the preceding 3 paragraphs.
