Artificial intelligence (AI) techniques are used to create convincing deepfakes. The main counter method is deepfake detection. Currently, most of the mainstream detectors are based on deep neural networks. Such deep learning detection frameworks often face several problems that need to be addressed, for example, dependence on large-annotated datasets, lack of interpretability, and limited attention to source traceability. Towards overcoming these limitations, in this paper, we propose a novel training-free deepfake detection framework based on the interpretable inherent source attribution. The proposed framework not only distinguishes between real and fake videos but also traces their origins using camera fingerprints. Moreover, we have also constructed a new deepfake video dataset from 10 distinct camera devices. Experimental evaluations on multiple datasets show that the proposed method can attain high detection accuracies (ACCs) comparable to state-of-the-art (SOTA) deep learning techniques and also has superior traceability capabilities. This framework provides a robust and efficient solution for deepfake video authentication and source attribution, thus, making it highly adaptable to real-world scenarios.</p>\u0000 </div>","PeriodicalId":48821,"journal":{"name":"IET Biometrics","volume":"2025 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bme2/5687970","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond their forensic significance, they can offer insights into physiological traits like blood groups and gender, which can help in forensic analysis to narrow down the search. This exploratory study aims to identify potential associations between fingerprint patterns, gender, and blood groups within a defined regional cohort in Kathmandu, Nepal. This preliminary study included 290 students (144 males and 146 females) from Himalayan Whitehouse International College (HWIC). Fingerprint patterns (loops, whorls, and arches) were analyzed and compared with participants’ ABO-Rh blood groups. Statistical analyses, including chi-square tests, were used to determine associations and trends. Loops emerged as the most common fingerprint pattern (57.14%), followed by whorls (35%), and arches (7.86%). Blood group B+ve was the most prevalent (33.1%) among the study population in Kathmandu. The significant association between gender and fingerprint pattern was observed. The gender analysis revealed that loops were predominant in females, while males showed a higher frequency of whorls. While no significant relationship was observed between ABO blood groups and fingerprint patterns, a strong association was found between fingerprint patterns and Rh factor (<i>p</i> = 0.0496). Loops were more prevalent among Rh-positive (Rh+ve) individuals, while whorls were more common among Rh-negative (Rh−ve) individuals. Additionally, specific fingers were observed to have distinct fingerprint patterns more frequently. Arches were most prevalent in the index finger of both hands, loops were most abundant in both pinky finger, and left middle finger. Whorls were most frequently observed in ring finger of both hands and right thumb. The findings reinforce global patterns of blood group and fingerprint distribution, where Rh+ve individuals represent the majority and loops are most dominant fingerprint pattern. The gender-specific trends suggest the nuanced interplay of genetics, with females displaying a higher frequency of loops and males showing more whorls. Similarly, some blood group are more likely to exhibit a specific set of fingerprint patterns. This research clearly shows the gender-based differences and influence of genetic factors on fingerprint patterns, particularly the Rh factor. These findings contribute to the growing field of dermatoglyphics, with implications for forensic science, and population genetics.</p>\u0000 </div>","PeriodicalId":48821,"journal":{"name":"IET Biometrics","volume":"2025 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bme2/9993120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144323692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thoughtfully designed emotionally appealing products can evoke strong user responses, making them more attractive. Color, as a crucial attribute of products, is a significant aspect to consider in the process of emotional product design. However, users’ emotional perception of product colors is highly intricate and challenging to define. To address this, this research proposes a product color design concept that considers human emotion perception based on deep learning and cluster analysis. First, for a given product, a color style is chosen for rerendering, which is an emotional color image. Different emotional color images have distinct RGB color representations. Second, clustering methods are employed to establish relationships between various emotional color images and different colors, selecting emotionally close style images. Subsequently, through transfer learning techniques, specific grid structures are used to retrain network weights, allowing for the fusion design of style and content images. This process ultimately achieves emotional color rendering design based on emotional color clustering and transfer learning. Multiple sets of emotional color design examples demonstrate that the method proposed in this study can accurately fulfill the emotional color design requirements of products, thereby, offering practical applicability.
