摘要：

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. (C) 2004 Elsevier B.V. All rights reserved.
