With the continuous development of intelligent connected vehicle industry, cameras and other vehicle-mounted devices are widely used, so the amount of data collection is increasing. There is a large amount of sensitive information hidden in the image data generated by connected vehicles. Once the data leakage event occurs, it may cause very serious consequences. In order to improve the security of connected vehicle data and reduce the threat of sensitive information leakage in image data, this paper provides a desensitization process of connected vehicle image data, and desensitizes sensitive information based on instance segmentation technology. In this paper, a real road image dataset is collected, and realizes desensitization of the modified dataset based on proposed framework. © 2023 SPIE.

ITIL (IT Infrastructure Library) provides a framework of best practice guidance for IT service management based on process, and has grown to become the most widely accepted approach to IT service management in the world. ITIL processes are implemented so that they underpin the organization business, and play the core role in the framework. The paper presents ITIL process integration architecture in the context of organization environment from the viewpoint of security, knowledge, information, control and semantics. The architecture illustrates the integration relationships between ITIL processes and organization environment. Actually the ITIL processes are executed in the complex organization environment, and ITIL tools should be interactive with the organization systems. Finally we outline how the integration architecture can be implemented with Web services modeling, composition, scheduling, and other contemporary Web services technologies. The integration architecture facilitates our organization implementation of ITIL processes and tool. © 2008 IEEE.

As blockchain technology research continues to advance, named entity recognition within blockchain patent texts has emerged as a fundamental cornerstone for various other tasks. In light of the absence of a publicly accessible corpus within the current realm of blockchain technology, as well as the challenges posed by insufficient text semantic expression, the dearth of semantic features, and the intricacies associated with capturing diverse word vector representations. This paper us of annotated blockchain patent texts and proposes the MBBC MacBert-BiLSTM-CRF MBBC model for named entity recognition in blockchain patents. The model employs embedding the feature layer to vectorize the input text, enriching text information and mitigating polysemy issues. Text feature information is acquired through the long short-term memory network, and the conditional random field model is integrated to enforce label relationships, yielding an optimal label sequence. In this study, the accuracy rate of BAT (Blockchain Application technology, BAT) on the self-constructed corpus achieves 91%, with a recall rate of 96% and an Fl value of 93%, representing a notable enhancement compared to mainstream models. Ablation experiments further demonstrate that the model in this paper effectively performs named entity recognition tasks associated with blockchain technology and subject content. © COPYRIGHT SPIE.

Reliability of Cyber-Physical system (CPS) components substitution is an important issue for troubleshooting and system upgrading. In this paper, CPS components substitution is equated to CPS service substitution based on a service-oriented architecture of CPS. Then, a reliable workflow for CPS service substitution is proposed, which consists of two parts. One is a qualitative judgment method for CPS service substitution according to the relationship between service compatibility and substitution, based on Time-Space π-calculus with time operator and space operator. The other is a series of substitution processes from the judgment results above, based on service management theory. Finally, a case study is performed to show that how to apply the workflow to ensure CPS components' reliable substitution. The experiment result demonstrates that this workflow is reasonable and feasible. © 2012 IEEE.

In recent years, crowdsourced testing, which uses collective intelligence to solve complex software testing tasks has gained widespread attention in academia and industry. However, due to a large number of workers participating in crowdsourced testing tasks, the submitted test reports set is too large, making it difficult for developers to review test reports. Therefore, how to effectively process and integrate crowdsourced test reports is always a significant challenge in the crowdsourced testing process. This paper deals with the crowdsourced test reports processing, sorts out some achievements in this field in recent years, and classifies, summarizes, and compares existing research results from four directions: duplicated reports detection, test reports aggregation and classification, priority ranking, and reports summarization. Finally explored the possible research directions, opportunities and challenges of the crowdsourced test reports. © ICST Institute for computer Sciences, Social Informatics and Telecommunications Engineering. 2020.

With the growing of hazardous chemicals transportation, supervision system for hazardous chemicals transportation is getting more and more attention. In China, supervisory system for hazardous chemicals is limited to tracking by Global Positioning System (GPS), positioning and simple data collection and judgments which cannot achieve a real sense of risk pre-warning. The paper develops a system architecture based on cyber-physical systems (CPS) for specific application requirements of vehicle rollover warning, and proposes a collaborative model for rollover pre-warning which considering both the conventional and the external environmental factors. The feasibility of the proposed CPS system architecture and collaborative model is then proved by designing and implementing a monitoring system for rollover warning of hazardous chemicals vehicle. © 2012 IEEE.

Blockchain is a decentralized, trust-free distributed ledger technology which has been applied in various fields such as finance, supply chain, and asset management. However, the network isolation between blockchains has limited their interoperability in asset exchange and business collaboration since it forms blockchain islands. Cross-chain is an important technology aiming to realize the interoperability between blockchains, and has become one of the hottest research topics in this area. This paper proposes a cross-chain transaction model based on improved hash locking consulted by the notary and users, which can solve the security problems in traditional hash locking. It can prevent malicious participants from creating large traffic blocking channels based on the key of unlocking condition. At the same time, the scheme of notary multi-signature is designed to solve the problem of lack of trust in traditional model. The transaction process of cross-chain, key agreement, cooperation mechanism of cross-chain, and security analysis based on the model is given in detail. Experiments of cross-chain transactions are implemented in Ethereum private chain, and prove that the proposed model has good application abilities. © 2020, Springer Nature Singapore Pte Ltd.

In mobile edge computing (MEC), task offloading can significantly reduce task execution latency and energy consumption of end user (EU). However, edge server (ES) resources are limited, necessitating efficient allocation to ensure the sustainable and healthy development for MEC system. In this paper, we propose a dynamic pricing mechanism based near-optimal resource allocation for elastic edge offloading. First, we construct a resource pricing model and accordingly develop the utility functions for both EU and ES, the optimal pricing model parameters are derived by optimizing the utility functions. In the meantime, our theoretical analysis reveals that the EU's utility function reaches a local maximum within the search range, but exhibits barely growth with increased resource allocation beyond this point. To this end, we further propose the Dynamic Inertia and Speed-Constrained particle swarm optimization (DISC-PSO) algorithm, which efficiently identifies the near-optimal resource allocation. Comprehensive simulation results validate the effectiveness of DISC-PSO algorithm, demonstrating that it significantly outperforms existing schemes by reducing the average number of iterations to reach a near-optimal solution by 86.88%, increasing the EU utility function value by 0.13%, and decreasing the variance of results by 96.78%. © 2025 IEEE.
