Identifying tampering operations in image operator chains based on decision fusion

作者：

Highlights：

• A decision fusion method is proposed to detect operations in operator chains.

• The method integrates information obtained by several forensic algorithms.

• A strategy for credibility calculation among different evidence is designed.

• The method has better identification performance against some existing methods.
