Google opens SynthID detector as Nigeria eyes election deepfakes
Google has made SynthID Detector publicly available worldwide in English, giving journalists, fact-checkers and ordinary users a way to upload images, video or audio and check for invisible AI watermarks from supported systems. The tool matters for Nigeria because the next election cycle is already raising concerns about deepfakes, cloned voices and fabricated campaign material moving quickly through social media and messaging apps. Its limits are just as important as its promise: SynthID can only detect recognised watermarks from Google and participating companies such as OpenAI, NVIDIA and Kakao, with Apple expected later, so a clean result does not prove a file is genuine. For Nigerian newsrooms and voters, it adds one useful check, but not a replacement for source tracing, metadata checks and conventional verification.
