摘要： 数字对象惟一标识符(digital object identifier,DOI)是对包括互联网信息在内的数字信息进行标识的一种工具。在传统的出版物中,书刊、磁带、光盘都有国际标准编号(ISBN、ISSN、ISCN)及其条形码作为出版物的惟一标识。这些标识使出版物得到有效的管理,便于读者查找和利用。

关键词： 标识符   DOI   文献   Object   规范化管理   数字对象   国际标准   有效工具  

摘要： DOI,即数字对象唯一标识,为英文Digital Object Identification的缩写。根据国际标准ISO 26324里的解释,它的意思是“一个对象的数字标识符”。这个标识符具有唯一性、永久性的特点。DOI是规范化管理、组织、共享、利用数字资源的有效工具。随着信息技术和互联网的发展,DOI目前已在国际出版界得到广泛推广应用。期刊的DOI标识符,是每篇论文的“身份标识”,通过DOI标识符可以迅速检索到该文献。

关键词： 船舶自动识别系统   标识符  

摘要： 当前,基于船舶自动识别系统的虚拟航标技术已经得到广泛应用,但其对沉船缺乏直观标识的手段,影响了碍航物的指示效果。本文针对船载显示终端对实时沉船信息的显示问题,对沉船实时位置标识信息的传输模式进行研究,设计了基于AIS/ASM广播报文的实时沉船报文格式,为实现实时沉船标识符在导航设备中的应用提供了借鉴。

关键词： Dental records   forensic anthropology   forensic dentistry   orthodontics  

摘要： Orthodontic records, such as photographs, radiographs, and dental casts, provide information useful for identification purposes because it may reveal important morphological, therapeutic, and pathological dental identifiers. Among these identifiers, the type and position of orthodontic appliances figure as distinctive tools for human identification. In this context, the present study aims to report an uncommon case of identification of a putrefied body, found near to a forest region in Brazil. The postmortem (PM) examination showed that the victim had part of a fixed orthodontic appliance installed in the maxillary and mandibular dental arches. To identify the body, relatives of the potential victim presented orthodontic examinations containing panoramic radiography and photographs of the orthodontic treatment. The body was identified based on the analysis of the radiographs and photographs that confirmed the presence of the orthodontic appliances observed PM. More specifically, the identification was supported by the analysis of bracket bonding position of the maxillary and mandibular incisors and the presence of distinctive morphological traits of the canines and incisors, as well dental roots observed radiographically. The present case highlights the importance of orthodontic records as a source of morphological dental identifiers for cases in which only unrestored teeth are available.

关键词： Hierarchical identity-based encryption   Authorized delegation   Encryption privacy   Identifier discrimination  

摘要： It has been almost one and a half decades since the introduction of the concept of hierarchical identity-based encryption (HIBE) systems, and many pairing-based HIBE systems have been proposed;however, how to achieve independent private key delegation in HIBE systems is still open. Independent private key delegation in HIBE systems requires that the following three conditions are satisfied: (1) private keys are not valid delegation credentials for deriving descendants' private keys, (2) any entity intending to derive a private key for any one of its descendants should own a valid delegation credential distributed by the root private key generator (PKG), and (3) a credential is only valid for deriving private keys for a given descendant. We present a new technique for composing private keys for entities in HIBE systems that we call identifier discrimination, aiming at resolving the problem of independent private key delegation. With the technique, we construct a selective identity secure HIBE system under the decisional bilinear Diffie-Hellman (DBDH) assumption in the standard model with the following properties. (1) Every entity in the HIBE system is prevented from deriving private keys for its descendants with the only use of its private key and the public parameters. (2) The root PKG can delegate the privilege (if needed) of generating private keys for each individual entity to any of its ancestors through authorization that we call authorized delegation, by distributing a specifically crafted secret (delegation credential) to the ancestor. (3) The encryption privacy of each ciphertext for its intended recipient is achieved, that is, ciphertexts encrypted on identity of any entity cannot be decrypted by any of its ancestors that we call dedicated encryption privacy.

关键词： facility management   identifiers   IoT   modularization   regular expression  

摘要： This paper is to propose an information management technique, which is easy to understand by humans and easy to utile analysis program, in order to manage complicated machines and facilities. To manage the facilities, we show a modeling that partly defines the structure of the facilities by set theory, further defines the requirements for joining the subset of structured identifiers on consistency. In verification of the proposal and programming method, we show how to control the amount of information of structured identifier as uniquely identifier. As a result, we show our proposal is useful to address real problems in management software.
