Federated learning is an important distributed model training technique in Internet of Things(IoT),in which participant selection is a key component that plays a role in improving training efficiency and model accuracy.This module enables a central server to select a subset of participants to performmodel training based on data and device information.By doing so,selected participants are rewarded and actively perform model training,while participants that are detrimental to training efficiency and model accuracy are excluded.However,in practice,participants may suspect that the central server may have miscalculated and thus not made the selection honestly.This lack of trustworthiness problem,which can demotivate participants,has received little attention.Another problem that has received little attention is the leakage of participants’private information during the selection process.We will therefore propose a federated learning framework with auditable participant selection.It supports smart contracts in selecting a set of suitable participants based on their training loss without compromising the privacy.Considering the possibility of malicious campaigning and impersonation of participants,the framework employs commitment schemes and zero-knowledge proofs to counteract these malicious behaviors.Finally,we analyze the security of the framework and conduct a series of experiments to demonstrate that the framework can effectively improve the efficiency of federated learning. 展开更多

Currently,there is a growing trend among users to store their data in the cloud.However,the cloud is vulnerable to persistent data corruption risks arising from equipment failures and hacker attacks.Additionally,when users perform file operations,the semantic integrity of the data can be compromised.Ensuring both data integrity and semantic correctness has become a critical issue that requires attention.We introduce a pioneering solution called Sec-Auditor,the first of its kind with the ability to verify data integrity and semantic correctness simultaneously,while maintaining a constant communication cost independent of the audited data volume.Sec-Auditor also supports public auditing,enabling anyone with access to public information to conduct data audits.This feature makes Sec-Auditor highly adaptable to open data environments,such as the cloud.In Sec-Auditor,users are assigned specific rules that are utilized to verify the accuracy of data semantic.Furthermore,users are given the flexibility to update their own rules as needed.We conduct in-depth analyses of the correctness and security of Sec-Auditor.We also compare several important security attributes with existing schemes,demonstrating the superior properties of Sec-Auditor.Evaluation results demonstrate that even for time-consuming file upload operations,our solution is more efficient than the comparison one. 展开更多

With the intelligentization of the Internet of Vehicles(lovs),Artificial Intelligence(Al)technology is becoming more and more essential,especially deep learning.Federated Deep Learning(FDL)is a novel distributed machine learning technology and is able to address the challenges like data security,privacy risks,and huge communication overheads from big raw data sets.However,FDL can only guarantee data security and privacy among multiple clients during data training.If the data sets stored locally in clients are corrupted,including being tampered with and lost,the training results of the FDL in intelligent IoVs must be negatively affected.In this paper,we are the first to design a secure data auditing protocol to guarantee the integrity and availability of data sets in FDL-empowered IoVs.Specifically,the cuckoo filter and Reed-Solomon codes are utilized to guarantee error tolerance,including efficient corrupted data locating and recovery.In addition,a novel data structure,Skip Hash Table(SHT)is designed to optimize data dynamics.Finally,we illustrate the security of the scheme with the Computational Diffie-Hellman(CDH)assumption on bilinear groups.Sufficient theoretical analyses and performance evaluations demonstrate the security and efficiency of our scheme for data sets in FDL-empowered IoVs. 展开更多

As a unique environmental regulation in China,the official accountability audit was piloted in 2014.With a focus on prioritizing the ecological environment,officials in pilot districts have implemented economic construction,adjusted industrial structures,and promoted coordinated development between the economy and environment.The effects of implementation have garnered widespread attention from society.However,there is limited research on the impact of an accountability audit on industrial structure adjustments.Using the“Accountability Audit of Officials for Natural Resource Assets(Trial)”released in 2015 as a quasi-natural experiment,this study collected panel data from 279 cities between 2013 and 2017.It then empirically analyzed the impact mechanism and effects of the accountability audit on industrial structure adjustment using the Propensity Score Matching and Difference-in-Differences model.The research findings indicate that the accountability audit directly impacted industrial structure adjustment,promoting the upgrading of the primary industry to the secondary industry and restricting the development of the tertiary industry.In addition,the audit is beneficial for enterprise entry,but not conducive to technological innovation,and has no significant impact on foreign direct investment.This conclusion fills a gap in the existing research and provides valuable insights for policymakers. 展开更多

Background: Appropriate sample requesting, collecting and timely dispatch to the appropriate laboratory is essential in establishing diagnosis of pathologies with lesions. Much time and effort may be wasted if this is not done according to certain standards. We conducted this study to assess the route of lymph node samples from requests to reaching the laboratories. Methods: We conducted an audit over a period from 4th June until 10th Aug 2023. Data for all the procedures performed over this period on lymph node samples (was entered into and analysed using Excel. Results: A total of eighteen samples for sixteen patients were obtained during this period. Median age of the patients was 34 years (19 - 73) with a M:F ratio of 5:11. Among the IR samples, nine samples were from the neck, three from inguinal area and one from axilla. Seven samples (53.8%) were tru-cut biopsies, six samples (46.15%) were FNA. All samples were sent to the pathology laboratory fixed in formalin. Samples for TB were sent only for five cases (31.25%) and for only two cases (12.5%) were samples sent for bacterial culture. For the OR samples, none were sent for either bacterial culture or TB. Overall, eight patients (50%) were not investigated for any infectious etiologies like brucella, toxoplasmosis, CMV, EBV plus other possible causes. Repeat sampling was required for 25% of patients (within and out of the audit period). Conclusions: to avoid delays in making diagnoses, it is paramount to consider infectious etiologies as possible diagnosis for lymphadenopathy and request appropriate investigations. This requires liaising with infectious diseases/clinical microbiology experts to guide regarding types of samples, types of media and timely dispatch to the correct laboratory. 展开更多

This paper provides empirical evidence on audit quality in Kazakhstan as measured by audit tenure and the frequency of issuing modified opinions. In addition, an overview of audit institutions of Kazakhstan and an analysis of the current audit market for public companies are offered. This paper also sheds light upon the potential independence problems resulting in low audit quality and current barriers to audit researches in Kazakhstan. Consistent with the findings of extant researches on audit quality and the general perceptions of investors, two hypotheses were developed, i.e., the audits performed by Big 4 audit firms in Kazakhstan also have higher quality than non-Big 4 audit firms in terms of audit tenure and the frequency of issuing modified opinions. The result confirms the hypothesis that Big 4 audit firms provide higher audit quality than smaller local firms in association with audit tenure instead of in relation to the frequency of issuing modified opinions. The result indicates that Big 4 audit firms may not be as independent as they will be in a highly litigious market. Therefore, an independent inspection should be regularly implemented according to the audit law, and the inspection report should be publicized by Chamber of Auditors (COA)1. If this is not practical due to the lack of qualified inspectors, a peer review may be an altemative to implement the quality control policy immediately. To the author's best knowledge, this is the first audit quality research in countries of the Commonwealth of Independence States (CIS). 展开更多

A GIS audit framework is necessary considering the diverse nature of GIS with regard to components, applications and industry. In practice, checklists are generated during the audit process based on specific objectives. There is no standardized list of items that can be used as a reference. The purpose of this study was to develop a GIS audit framework as a foundation for GIS audits. The framework provides that comprehensive approach to various GIS aspects during the audit process. The design builds on a developed conceptual framework where most significant categories of GIS audit parameters namely data quality, software utilization, GIS competency and procedures (work flows) were identified. The study adopted a reductive model approach to simplify the complexity associated with each category of GIS audit parameter. The resultant audit elements for each category are organized in a matrix that forms an integral part of the framework. The columns comprise audit goal, audit questions and audit subjects as indicators which are qualitatively measured. The rows comprise the parameters (data quality, software utilization, personnel competency and procedure (workflows)). To use the framework, an auditor only needs to create an audit checklist that consists of particular parameters and indicators from the framework depending on audit objective. As part of an on-going research, the next step will involve validating the framework through a mock testing process. 展开更多

As a crucial supervisory department overseeing economic operations,the audit department plays a pivotal role in safeguarding the healthy development of the country’s economy,exposing corruption,and effectively maintaining social and economic peace and stability.The work of auditing involves detecting existing issues,providing remedies,and consistently contributing to national governance.However,as the market economic environment undergoes continuous changes,legal systems advance,and the audit environment becomes more complex,audit risks have gradually gained prominence.The prevention of audit risks has increasingly captured the attention of audit agencies at all levels.This necessitates audit institutions to continually adapt to new challenges,comprehend risks,and exert effective control over them.This article delves into the causes of audit risks,exploring ways to effectively identify and respond to these risks within a complex and ever-changing environment.The objective is to ensure the objectivity and accuracy of audit reports,allowing the audit function to truly serve as an“immune”system,protecting public interests. 展开更多

Nowadays, earnings management is a hot issue, but most of the researches focus on the incentives of earnings management and few of them refer to the effect of audit quality on earnings management. In this study, we directly examine the effect of external audit quality on earnings management by using discretionary accruals. We find that the discretionary accruals of non-dual audit companies are significantly greater than those of dual audit companies. We also find that clients of non-First Ten auditors intend to report greater discretionary accruals than those of First Ten auditors. 展开更多

The setting-up of the Malaysian Audit Oversight Board (AOB) in 2010 under the Securities Commission Amendment Act 2010 has extended the role of regulators into the statutory audit domain for public listed companies. Although the auditing profession in Malaysia has International Auditing Standards as prescribed minimum level of quality in the delivery of audit assurance services, self-regulation by the profession alone appears inadequate to ensure the delivery of quality audit services. With co-regulation, auditors now are monitored not just by the profession but also by a new statutory body with considerable regulatory powers to sanction auditors where quality of the audit process has been found wanting. This study solicits the opinions of auditors on their expectations of what the new regulator can achieve. Based on interviews with a sample of 30 auditors, the study finds that the majority believe that audit quality will be taken to a new level following AOB's remit of registration of auditors, compliance inspection with International Standard on Quality Control (ISQC), monitoring of financial statement quality, and its power of sanctions. A review of AOB's early years' inspection confirms these expectations. 展开更多

In this paper,we focus on providing data provenance auditing schemes for distributed denial of service(DDoS)defense in intelligent internet of things(IoT).To achieve effective DDoS defense,we introduce a two-layer collaborative blockchain framework to support data auditing.Specifically,using data scattered among intelligent IoT devices,switch gateways self-assemble a layer of blockchain in the local autonomous system(AS),and the main chain with controller participation can be aggregated by its associated layer of blocks once a cycle,to obtain a global security model.To optimize the processing delay of the security model,we propose a process of data pre-validation with the goal of ensuring data consistency while satisfying overhead requirements.Since the flood of identity spoofing packets,it is difficult to solve the identity consistency of data with traditional detection methods,and accountability cannot be pursued afterwards.Thus,we proposed a Packet Traceback Telemetry(PTT)scheme,based on in-band telemetry,to solve the problem.Specifically,the PTT scheme is executed on the distributed switch side,the controller to schedule and select routing policies.Moreover,a tracing probabilistic optimization is embedded into the PTT scheme to accelerate path reconstruction and save device resources.Simulation results show that the PTT scheme can reconstruct address spoofing packet forward path,reduce the resource consumption compared with existing tracing scheme.Data tracing audit method has fine-grained detection and feasible performance. 展开更多
