提出了一种用于图像认证和篡改检测的脆弱水印算法。它使用梯度图像及其结构来实现定位和安全要求。它提供了卓越的本地化和更高的安全性，可以抵御包括矢量量化攻击在内的许多攻击。
A fragile watermarking algorithm for image authentication and tamper detection is proposed. It uses a gradient image and its structure to achieve localization and security requirements. It provides superior localization with greater security against many attacks including vector quantization attack.
