These techniques modify coefficients of compressed codes to embed authentication information, and the marked compressed codes can be decoded to generate an image that is similar to the original one.…”

“…Therefore, protecting the transmitted AMBTC codes has become increasingly crucial for real applications. To protect the compressed codes from being tampered, several authentication techniques designed for AMBTC compressed images [9][10][11][12][13][14][15][16][17][18] have been investigated and gained wide attention due to the applicability of AMBTC.…”

“…The early works [11][12][13][14] for authenticating AMBTC compressed codes mainly focus on the capability of detecting tampered trios. In addition to the detection performance, recent works [15][16][17][18] have paid more effort on improving the marked image quality by using reference table (RT) based embedding techniques [19][20][21] or adding the capability of recovery the tampered trios for some special applications [22]. Li et al [15] present a RT-based AMBTC authentication scheme, in which two digits of base λ are embedded into a compressed trio using a RT of size λ×λ.…”

Chen and Chang [17] notice that the bitmap in method [15] is unprotected, and present a new scheme such that the alteration of bitmap is detectable.

The existing tamper detection schemes for absolute moment block truncation coding (AMBTC) compressed images are able to detect the tampering. However, the marked image qualities of these schemes can be enhanced, and their authentication methods may fail to detect some special tampering. We propose a secure AMBTC tamper detection scheme that preserves high image fidelity with excellent detectability. In the proposed approach, a bit in bitmaps of AMBTC codes is sequentially toggled to generate a set of authentication codes. The one that causes the least distortion is embedded into the quantization levels with the guidance of a key-generated reference table (RT). Without the correct key, the same reference table cannot be constructed. Therefore, the proposed method is able to detect various kinds of malicious tampering, including those special tampering techniques designed for RT-based authentication schemes. The proposed method not only offers better image quality, but also provides an excellent and satisfactory detectability as compared with previous works.
