With the rapid expansion of the Internet of Things(IoT),user data has experienced exponential growth,leading to increasing concerns about the security and integrity of data stored in the cloud.Traditional schemes relying on untrusted third-party auditors suffer from both security and efficiency issues,while existing decentralized blockchain-based auditing solutions still face shortcomings in correctness and security.This paper proposes an improved blockchain-based cloud auditing scheme,with the following core contributions:Identifying critical logical contradictions in the original scheme,thereby establishing the foundation for the correctness of cloud auditing;Designing an enhanced mechanism that integrates multiple hashing with dynamic aggregate signatures,binding encrypted blocks through bilinear pairings and BLS signatures,and improving the scheme by setting parameters based on the Computational Diffie-Hellman(CDH)problem,significantly strengthening data integrity protection and anti-forgery capabilities;Introducing a random challenge mechanism and dynamic parameter adjustment strategy,effectively resisting various attacks such as forgery,tampering,and deletion,significantly improving the detection probability of malicious Cloud Service Providers(CSPs),and significantly reducing the proof generation overhead for CSPswhilemaintaining the same computational cost forDataOwners.Theoretical analysis and performance evaluation experiments demonstrate that the proposed scheme achieves significant improvements in both security and efficiency.Finally,the paper explores potential applications of the Enhanced Security Scheme in fields such as healthcare,drone swarms,and government office attendance systems,providing an effective approach for building secure,efficient,and decentralized cloud auditing systems. 展开更多

The unprecedented scale of large models,such as large language models(LLMs)and text-to-image diffusion models,has raised critical concerns about the unauthorized use of copyrighted data during model training.These concerns have spurred a growing demand for dataset copyright auditing techniques,which aim to detect and verify potential infringements in the training data of commercial AI systems.This paper presents a survey of existing auditing solutions,categorizing them across key dimensions:data modality,model training stage,data overlap scenarios,and model access levels.We highlight major trends,including the prevalence of black-box auditing methods and the emphasis on fine-tuning rather than pre-training.Through an in-depth analysis of 12 representative works,we extract four key observations that reveal the limitations of current methods.Furthermore,we identify three open challenges and propose future directions for robust,multimodal,and scalable auditing solutions.Our findings underscore the urgent need to establish standardized benchmarks and develop auditing frameworks that are resilient to low watermark densities and applicable in diverse deployment settings. 展开更多

With the deep integration of digital technology and the real economy,AI auditing has emerged as a core paradigm that breaks through the pain points of traditional auditing,such as“sampling limitations,post-event lag,and reliance on manual labor”.This paper systematically reviews the theoretical connotations of AI auditing,reveals its current practical status,deeply analyzes four core challenges:data quality,ethical compliance,talent adaptation,and institutional synergy,and proposes feasible development paths from four dimensions:technological optimization,institutional construction,talent cultivation,and industry synergy.The research indicates that AI auditing needs to be“based on data elements,driven by technological innovation,with institutional guarantees as the bottom line,and talent adaptation as the core”,and achieve an upgrade from“tool assistance”to“governance synergy”under the promotion of new productive forces. 展开更多

Cloud storage,a core component of cloud computing,plays a vital role in the storage and management of data.Electronic Health Records(EHRs),which document users’health information,are typically stored on cloud servers.However,users’sensitive data would then become unregulated.In the event of data loss,cloud storage providers might conceal the fact that data has been compromised to protect their reputation and mitigate losses.Ensuring the integrity of data stored in the cloud remains a pressing issue that urgently needs to be addressed.In this paper,we propose a data auditing scheme for cloud-based EHRs that incorporates recoverability and batch auditing,alongside a thorough security and performance evaluation.Our scheme builds upon the indistinguishability-based privacy-preserving auditing approach proposed by Zhou et al.We identify that this scheme is insecure and vulnerable to forgery attacks on data storage proofs.To address these vulnerabilities,we enhanced the auditing process using masking techniques and designed new algorithms to strengthen security.We also provide formal proof of the security of the signature algorithm and the auditing scheme.Furthermore,our results show that our scheme effectively protects user privacy and is resilient against malicious attacks.Experimental results indicate that our scheme is not only secure and efficient but also supports batch auditing of cloud data.Specifically,when auditing 10,000 users,batch auditing reduces computational overhead by 101 s compared to normal auditing. 展开更多

This paper examines the role of internal audit and the incorporation of Environmental,Social,and Governance(ESG)factors within the corporate governance frameworks of Greek firms in mitigating their financial risk.Time series econometric analysis was performed to determine the factors that influence financial stability,transparency,and regulatory compliance in Greek Firms.Data were collected from 120 internal auditors and financial professionals employed in organizations across multiple sectors of the Greek economy.In line with existing literature,findings show that robust internal audit and ESG practices are essential in promoting financial stability,transparency,and regulatory compliance.The paper provides empirical evidence that well-structured internal audit mechanisms and effective ESG initiatives reduce financial risks,while enhancing organizational sustainability and resilience.The results emphasize the growing importance of ESG considerations in corporate governance and suggest that improvements in both internal audit systems,as well as robust ESG policies,can strengthen risk management strategies and improve long-term financial performance.While previous research has thoroughly investigated the impact of internal audits on financial stability and the influence of ESG on corporate sustainability,this paper specifically examines their combined effect on financial risk management.Using firm level data across various sectors of the Greek economy,this study provides insights into how internal audit and ESG policies can jointly contribute towards enhancing financial resilience,transparency,and regulatory compliance. 展开更多

This study explores ethical violations and audit failures in various large-scale corporate fraud cases.Using a qualitative descriptive method and based on secondary data from documented fraud cases and published audit reports,the study applies the Fraud Triangle framework,focusing on how weak integrity,objectivity,and professional competence have undermined public trust in the auditing profession.Using a qualitative descriptive method and the Fraud Triangle framework,which includes pressure,opportunity,and rationalization,the study analyzes cases from Indonesia(SNP Finance,Jiwasraya),China(Evergrande),and Germany(Wirecard).The analysis reveals that many audit failures observed in this study appear to stem more from ethical challenges than from technical incapability,driven by client pressure,weak internal controls,and compromised auditor independence.These cases demonstrate a recurring global pattern in which auditors neglect their responsibility to act in the public interest. 展开更多

Based on the objective reality that audit risk responsibility has mainly been attributed to certified public accountants in the past,and audit standards have not specifically divided the entities responsible for audit risk responsibility,combined with the understanding of the types of audit risk elements related to audit standards,the differences in the understanding of audit risk and its relationship model application caused by the different audit cultures in China and the West have led to a bias of Chinese certified public accountants to bear inspection risks,which affects their professional enthusiasm and continues to cause accounting firms to be lazy in audit quality management.Based on this,literature research,case analysis,and logical deduction methods were used to redefine the concept of audit risk from the perspective of risk responsibility subjects.The traditional audit risk elements and their relationship models were briefly introduced,and the identification of audit risk elements and optimization of audit risk relationship models were systematically demonstrated. 展开更多
