Here, we present a hierarchical dual-strategy framework for selective knowledge unlearning in medical LLMs that enables precise removal of specialised knowledge whilst preserving fundamental medical competencies, specifically addressing challenges in biomedical and healthcare intelligence using imperfect data. Our approach synergistically integrates geometric-constrained gradient updates, which selectively modulate parameters encoding target knowledge while safeguarding essential capabilities, with concept-aware token-level interventions that systematically distinguish between preservation-critical and unlearning-targeted tokens through a unified four-level medical concept hierarchy. Through comprehensive evaluation on the MedMCQA dataset targeting surgical knowledge removal, and cross-domain validation on the MHQA dataset encompassing anxiety, depression, trauma, and obsessive-compulsive disorder domains, we demonstrate that our method achieves superior selective unlearning performance (82.7% forgetting rate, 88.5% knowledge preservation) compared to existing approaches. Notably, our framework maintains robust privacy guarantees while requiring modification of only 0.1% of model parameters, establishing a paradigm for privacy-preserving medical AI systems that addresses regulatory compliance, hospital auditability, and ethical imperatives in clinical research environments. This work contributes to advancing biomedical and healthcare intelligence by providing an effective solution for auditing and managing imperfect and privacy-sensitive medical data in real-world clinical applications.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"6681-6690"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148836838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While these devices enhance convenience and automation, they generate massive amounts of visual data containing sensitive personal information, thereby increasing the risk of privacy leakage and challenging traditional encryption methods in consumer IoT networks. To address this issue, a cryptanalysis-driven image encryption scheme via a chaos-based 3D S-box and genetic code is proposed, specifically designed to safeguard visual privacy in consumer applications. First, a novel dynamical architecture, formally termed 3D Non-degenerate Hyperchaos (3D-NDHC), is constructed to serve as a robust entropy source. Explicitly defined as a globally bounded volume-expanding hyperchaotic system, 3D-NDHC distinguishes itself from traditional dissipative maps by exhibiting global robust hyperchaos and scalable complexity, where the Lyapunov exponents grow logarithmically with control parameters, ensuring high unpredictability. Next, a dynamically generated three-dimensional S-box driven by these chaotic sequences is introduced to perform efficient image permutation. Subsequently, a genetic code method enhanced by cryptanalysis is applied to confuse the permuted image matrix, specifically addressing the security vulnerabilities often inherent in lightweight encryption algorithms. Finally, under the control of pseudo-chaotic sequences, a lightweight wave diffusion process is employed to spread the pixel values and produce the final ciphertext image. In contrast to conventional algorithms that rely on standard encryption techniques, the proposed approach integrates a chaos-driven 3D S-box with a cryptanalysis-enhanced genetic code scheme. This combination introduces a high level of confusion and diffusion, significantly increasing the difficulty for attackers attempting to illegally decrypt sensitive images from smart devices. Experimental results and security analyses demonstrate that the scheme effectively resists various cryptographic attacks and outperforms several recently proposed image encryption algorithms, offering a robust solution for protecting digital image privacy in smart home environments.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"5483-5494"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CDAuth employs a universally applicable multi-factor authentication approach, integrating pseudo-identity, attribute concealment, and biometric hiding. The authentication information sets can be freely added or modified to accommodate various access scenarios. This boosts privacy, flexibility, and applicability compared to traditional methods. Furthermore, multi-edge servers as Certification Authorities (CAs) store only the union of terminal attributes and a verification token per user in their subdomains, instead of each user’s attribute and biometric sets as in traditional schemes, significantly reducing storage consumption. Additionally, replacing the bilinear pairing operations with the native group operations, while maintaining security, significantly reduces computational consumption. Our analysis shows that CDAuth can resist common security attacks and is more efficient than the previous schemes.","PeriodicalId":13208,"journal":{"name":"IEEE Transactions on Consumer Electronics","volume":"72 3","pages":"5897-5910"},"PeriodicalIF":9.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The framework integrates fine-grained sentiment classification, transaction anomaly detection, and trading recommendation. The key novelty lies in the design of an anomaly detection mechanism that is aware of sentiment dynamics and links social media sentiment to consumer trading guidance.

Despite the deployment of robust encryption protocols (e.g., TLS 1.3 and QUIC) to protect user confidentiality, side-channel information leaking from encrypted traffic remains a significant privacy threat. However, accurately identifying specific video content is increasingly challenging due to complex Adaptive Bitrate (ABR) algorithms, which homogenize traffic patterns, especially in high-motion viral content. Existing methods relying on simple statistical features or single-view deep learning models often struggle to capture the fine-grained fingerprints of specific videos under these conditions. In this paper, we propose a novel Multi-View Fusion Network, namely Rocket-Transformer Fusion (RTF-Net), that integrates time-domain convolutional features with frequency-domain attention mechanisms. Our approach utilizes MiniRocket to extract deterministic sequential patterns from traffic bursts, while simultaneously employing Fast Fourier Transform (FFT) combined with TinyBERT to capture global periodic dependencies in the frequency domain. We evaluate our method on a self-collected dataset comprising 2,000 encrypted traffic traces generated from 20 most viral short dramas (each exceeding 100 million views) on TikTok. Experimental results demonstrate that our method achieves a state-of-the-art classification accuracy of 91.33% using only the first 30 seconds of viewing traffic, significantly outperforming other baseline machine learning algorithms, showing that side-channel leakage is indeed a threat to short video platforms.
