<h1>Team creates cryptographic 'voice signatures' for artist to prevent AI deepfakes, raising posthumous publicity and evidence law issues</h1> A prominent singer's associates are undertaking digital preservation of the artist's recorded voice to prevent unauthorised use, tampering, and AI-enabled impersonation by creating a verifiable 'digital signature' linked to archived recordings on public platforms. Legally, this raises issues of posthumous personality and publicity rights, authentication and provenance of audio evidence, and the need for technical markers to support attribution and enforcement against deepfake misuse. Effective protection will depend on robust cryptographic provenance, clear rights ownership, and available civil or criminal remedies under applicable intellectual property, data protection, and anti-fraud laws.
