    Enhancing Deepfake Detection: Proactive Forensics Techniques Using Digital Watermarking

    Zhimao Lai1,2, Saad Arif3, Cong Feng4, Guangjun Liao5, Chuntao Wang6,*

    CMC-Computers, Materials & Continua, Vol.82, No.1, pp. 73-102, 2025, DOI:10.32604/cmc.2024.059370 - 03 January 2025

    Abstract With the rapid advancement of visual generative models such as Generative Adversarial Networks (GANs) and stable Diffusion, the creation of highly realistic Deepfake through automated forgery has significantly progressed. This paper examines the advancements in Deepfake detection and defense technologies, emphasizing the shift from passive detection methods to proactive digital watermarking techniques. Passive detection methods, which involve extracting features from images or videos to identify forgeries, encounter challenges such as poor performance against unknown manipulation techniques and susceptibility to counter-forensic tactics. In contrast, proactive digital watermarking techniques embed specific markers into images or videos, facilitating More >

    A GAN-EfficientNet-Based Traceability Method for Malicious Code Variant Families

    Li Li*, Qing Zhang, Youran Kong

    CMC-Computers, Materials & Continua, Vol.80, No.1, pp. 801-818, 2024, DOI:10.32604/cmc.2024.051916 - 18 July 2024

    Abstract Due to the diversity and unpredictability of changes in malicious code, studying the traceability of variant families remains challenging. In this paper, we propose a GAN-EfficientNetV2-based method for tracing families of malicious code variants. This method leverages the similarity in layouts and textures between images of malicious code variants from the same source and their original family of malicious code images. The method includes a lightweight classifier and a simulator. The classifier utilizes the enhanced EfficientNetV2 to categorize malicious code images and can be easily deployed on mobile, embedded, and other devices. The simulator utilizes… More >

    Muhammad Shakeel Faridi1, Saqib Ali1,2,*, Guojun Wang2,*, Salman Afsar Awan1, Muhammad Zafar Iqbal3

    CMC-Computers, Materials & Continua, Vol.77, No.2, pp. 1837-1854, 2023, DOI:10.32604/cmc.2023.041929 - 29 November 2023

    Abstract Trustworthiness and product traceability are essential factors in the apparel industry 4.0 for establishing successful business relationships among stakeholders such as customers, manufacturers, suppliers, and consumers. Each stakeholder has implemented different technology-based systems to record and track product transactions. However, these systems work in silos, and there is no intra-system communication, leading to a lack of complete supply chain traceability for all apparel stakeholders. Moreover, apparel stakeholders are reluctant to share their business information with business competitors; thus, they involve third-party auditors to ensure the quality of the final product. Furthermore, the apparel manufacturing industry… More >

    Cross-Domain Data Traceability Mechanism Based on Blockchain

    Shoucai Zhao, Lifeng Cao*, Jinhui Li, Jiling Wan, Jinlong Bai

    CMC-Computers, Materials & Continua, Vol.76, No.2, pp. 2531-2549, 2023, DOI:10.32604/cmc.2023.040776 - 30 August 2023

    Abstract With the application and development of blockchain technology, many problems faced by blockchain traceability are gradually exposed. Such as cross-chain information collaboration, data separation and storage, multi-system, multi-security domain collaboration, etc. To solve these problems, it is proposed to construct trust domains based on federated chains. The public chain is used as the authorization chain to build a cross-domain data traceability mechanism applicable to multi-domain collaboration. First, the architecture of the blockchain cross-domain model is designed. Combined with the data access strategy and the decision mechanism, the open and transparent judgment of cross-domain permission and More >

    Application of Blockchain Sharding Technology in Chinese Medicine Traceability System

    Fuan Xiao1, Tong Lai1, Yutong Guan1, Jiaming Hong1, Honglai Zhang1, Guoyu Yang2, Zhengfei Wang1,*

    CMC-Computers, Materials & Continua, Vol.76, No.1, pp. 35-48, 2023, DOI:10.32604/cmc.2023.038937 - 08 June 2023

    Abstract Traditional Chinese Medicine (TCM) is one of the most promising programs for disease prevention and treatment. Meanwhile, the quality of TCM has garnered much attention. To ensure the quality of TCM, many works are based on the blockchain scheme to design the traceability scheme of TCM to trace its origin. Although these schemes can ensure the integrity, sharability, credibility, and immutability of TCM more effectively, many problems are exposed with the rapid growth of TCM data in blockchains, such as expensive overhead, performance bottlenecks, and the traditional blockchain architecture is unsuitable for TCM data with… More >

    Scalable Blockchain Technology for Tracking the Provenance of the Agri-Food

    B. Subashini*, D. Hemavathi

    CMC-Computers, Materials & Continua, Vol.75, No.2, pp. 3339-3358, 2023, DOI:10.32604/cmc.2023.035074 - 31 March 2023

    Abstract Due to an increase in agricultural mislabeling and carelesshandling of non-perishable foods in recent years, consumers have been calling for the food sector to be more transparent. Due to information dispersion between divisions and the propensity to record inaccurate data, current traceability solutions typically fail to provide reliable farm-to-fork histories ofproducts. The three most enticing characteristics of blockchain technology areopenness, integrity, and traceability, which make it a potentially crucial tool for guaranteeing the integrity and correctness of data. In this paper, we suggest a permissioned blockchain system run by organizations, such as regulatory bodies, to… More >

    Smart Contract to Traceability of Food Social Selling

    Cristian Valencia-Payan*, José Fernando Grass-Ramírez, Gustavo Ramirez-Gonzalez, Juan Carlos Corrales

    CMC-Computers, Materials & Continua, Vol.74, No.3, pp. 4703-4728, 2023, DOI:10.32604/cmc.2023.031554 - 28 December 2022

    Abstract Traditionally, food sustainability has been considered solely in the stage of agricultural production. However, globalization, the expansion of the food production industry, and the emergence of supermarket chains that control the retail food market require specific significant changes in supply chains in the food sector and, therefore, we need to address the economic, social, and environmental impacts of these events. On the other hand, social selling has increased rapidly in recent years, with a further boom, following current events related to the coronavirus disease (COVID-19). This explosion of social sales, where there are usually no… More >
