A Recoverable Image Authentication Scheme by Reed-Solomon Code

Wen-Chuan Wu,


Generally, image authentication is able to verify artificial images and then to repair their damages. However, most image authentication schemes require hiding authentication data and recovery data both due to the abilities of tamper detection and data recovery. As a result, our work attempts to draw a portion of specific features as the important authentication and recovery data at the same time for the purpose providing a better image quality and confirming image integrity. We first encode an image by vector quantization technique to produce its compression codes. Then, an error correction code, Reed-Solomon code, is applied to protect the preceding compression codes against some malicious tampering attacks. Experimental results showed that the proposed scheme could yield a satisfactory image quality. Moreover, the usage of Reed-Solomon code is also able to resist tampering attacks and to correct recovery data.
