The Internet of Things (IoT) connects physical and digital worlds with mobile devices, accompanied by a surge in cybersecurity issues. With the rapid adoption of mobile devices, mobile forensics emerges as a new interdisciplinary field that concerns many forms of sabotage and cybercrime in the context of mobile computing. One of the most common cyberattacks is tampering. Digital watermarking is a tamper-evident technique used to protect data integrity. In this paper, we present an antitamper image watermarking scheme designed for mobile communications with low computational cost. A reference matrix based on cellular network topology is introduced to guide the watermark embedding and extraction processes. This reference matrix serves as a lookup table to reduce computational complexity, thereby enabling efficient implementation on mobile devices. Our scheme is aimed at offering high accuracy in detecting and localizing tampered regions. We also achieve a high watermarking capacity while leaving the visual quality of the carrier images nearly unharmed. Experimental results validate the effectiveness of our scheme against various types of simulated forgery including cropping and copy/paste attacks.

“…After the preparation operation, three categories, smooth block, less complex block, and high complex block, of the AMBTC compression codes have been identified. A data embedding operation is conducted based on a turtle-shell reference matrix, called TSM, defined in [11] as shown in Fig. 3.…”

“…AMBTC's compression speed is relatively efficient and effective, and the PNSR of the decompressed image is better than other BTC variants. Many researchers treated the compression codes of AMBTC as cover media and studied how to apply different block classification strategies to achieve good performance on hiding capacity no matter their designed data hiding schemes with or without reversibility [11]- [16], [41], [42]. Chuang et al proposed a BTC-based data hiding method in 2006 [13] which classified BTC compression codes into smooth and edge categories by a pre-determined threshold, and embedded 16 bits secret data into each smooth block.…”

This paper proposes an innovative and novel steganography method for an AMBTC compressed image by combining a turtle-shell reference matrix and (7, 4) Hamming code, called hybrid strategy and block feature-based data hiding method (HBF-DH). Firstly, the proposed method compresses an original image by an AMBTC compression technique, and then applies a user predefined threshold pair to classify all compressed blocks into three categories: a smooth block, less complex block, and high complex block. Next, the smooth and less complex blocks are smoothed out with the aim of vacating more space for data hiding. The embedding process is divided into two phases. In the first phase, each quantization level pair of the AMBTC compression codes is used to embed an 8-ary secret digit by using a restrictive turtle-shell reference matrix. The second phase embeds binary secret data into a bitmap according to block characteristics. For smooth blocks, the bitmap is directly replaced as binary secret data by using bit replacement. For a less complex block, the binary secret data is concealed into a bitmap by using our proposed (7, 4) Hamming code based data hiding strategy, which increases the data hiding capacity without significant impact on image quality. The experimental results and analyses prove that the proposed HBF-DH method is superior to other existing AMBTC based data hiding methods in terms of data hiding ability with satisfactory image visual quality.INDEX TERMS Steganography, AMBTC, (7, 4) hamming code, turtle-shell reference matrix, high payload, block features.
