研究了非对称环境下基于传感器噪声的数字相机识别问题。我们主要关注指纹复制攻击，攻击者只能访问JPEG图像，而防御者可以利用未压缩的图像。这就导致了脆弱的传感器指纹的概念，这些指纹只对防御者可用，但不能在有损压缩中存活。用七种不同的摄像头进行的实验表明，只要不向公众公开高质量的图像，就可以高度可靠地检测到攻击。
We study digital camera identification based on sensor noise in an adversarial environment with asymmetries. We focus on fingerprint-copy attacks, where the attacker has access to JPEG images only, while the defender may leverage uncompressed images. This leads to the notion of fragile sensor fingerprints that are only available to the defender but do not survive lossy compression. Experiments with seven different cameras suggest a highly reliable detection of the attack as long as no high-quality images are shared with the public.
