This paper focuses on the changing process of global competition model based on the analysis of production model and its tendency of development, especially analyses the positive effect of mass customization. The paper introduces the concept of market turbulence to decide the occasion of transformation to mass customization for industries/enterprises. Several transformation roadmaps to mass customization and competitive models and strategies are established.展开更多

Decided by consumerism, hedonic consumption has got popular. Hedonic consumption makes people be personalized during consumption and brings a high degree of prosperity in consumption. But at the same time, for the materialization logic in consumerism, people has been enslaved by substance and involved in the vicious circle about unlimited demand for substance, which brought a series of problems in consumption. Nowadays, sharing consumption is rapidly developing, which leads to the change of consumption values. The application of big data in the consumer area, through bringing ＂big data sense＂ and solving information barrier, is one of the most important reasons to cause the change. This change can help to establish a fair consumption environment and harmonious consumption relations, which will make the economic development faster and better展开更多

Users can enjoy convenience by sending queries to LBS servers and obtaining service information that is nearby.However, these queries may leak the users' locations and interests to the un-trusted LBS servers, leading to serious privacy concerns. In this paper, we propose a Privacy-Preserving Pseudo-Location Updating System(3PLUS) to achieve k-anonymity for mobile users using LBSs. In 3PLUS, without relying on a third party, each user keeps pseudo-locations obtained from both the history locations and the encountered users, and randomly exchanges one of them with others when encounters occur. As a result, each user's buffer is disordered. A user can obtain any k locations from the buffer to achieve k-anonymity locally. The security analysis shows the security properties and our evaluation results indicate that the user's privacy is significantly improved.展开更多

文摘In an object-based storage system,a novel scheme named EAP(extending attributes page) is presented to enhance the metadata reliability of the system by adding the user object file information attributes page for each user object and storing the file-related attributes of each user object in object-based storage devices.The EAP scheme requires no additional hardware equipments compared to a general method which uses backup metadata servers to improve the metadata reliability.Leveraging a Markov chain,this paper compares the metadata reliability of the system using the EAP scheme with that using only metadata servers to offer the file metadata service.Our results demonstrate that the EAP scheme can dramatically enhance the reliability of storage system metadata.
