航空物探遥感地质资料定密工作初探与实践

在地质调查信息化与地质资料社会化服务工作不断发展的背景下,航空物探遥感地质资料的开发利用与保密管理工作矛盾日益凸显。本文以航空物探遥感资料定密为研究重点,总结了地质、测绘地理信息、海洋等工作领域的定密工作情况,基于对航空物探遥感地质资料分类结果提取了共性资料涉密要素/事项,根据保密法规的相关规定与要求,初步建立了以比例尺/空间精度、测绘地理信息要素、航空物探遥感专业要素为主的定密判定要素集,提出了航空物探遥感地质资料的定密工作原则与参考准则,以期为航空物探遥感地质信息共享服务提供必要的工作支撑。

试论保密的政治价值

研究保密实践的根本目的是满足政治需要、促进经济发展、保障国家安全、维护社会稳定。以科学发展观为指导,采用理论与实践相结合的方法,深刻洞察政治实践的内在需要,科学阐明保密实践服务服从于政治实践的特殊功能,系统阐述保密活动对于夺取国家政权、强化政治统治、改变政治格局的重要作用和价值。加强对保密政治价值的研究,在政治多元化、经济全球化的当今时代,具有特殊重要的意义。     

外包数据库机密性保护方法研究

外包数据库作为现代商业新兴的商业运作模式,正在受到越来越多的企业和组织的欢迎。而如何保障外包数据库的机密性,成为当前云计算应用研究的重点。本文基于现有的外包数据库安全性中的PMD、Hweehw查询验证的不足,提出了一种动态的数据库查询验证技术,从而节省了外包数据库的成本,并提高了验证速度。     

Research and confidentiality: Legal issues and risk management strategies.

Maintaining the confidentiality of research subjects and research data is essential to the research process. However, the legal landscape surrounding the concept of confidentiality is a dynamic one. This article discusses why confidentiality in research is important, various threats to it, efforts to protect it through a “researcher privilege,” as well as other statutory and regulatory provisions relevant to research confidentiality. The article concludes with a discussion of risk management tools that researchers concerned with maintaining confidentiality can use in the design and implementation of research.

A Review of “Children & Their Urban Environment: Changing Worlds”

Problem: Information is often suppressed when public infrastructure is planned by design-build-finance-operate (DFBO) public/private partnerships, an increasingly popular strategy for procuring transportation facilities, hospitals, and schools.

Purpose: I aim to identify strategies to increase transparency and accountability in large infrastructure projects delivered through public/private partnerships.

Methods: I studied the case of an award winning public/private partnership to plan a rapid rail line in Vancouver by comparing confidential documents released after project approval to the information available while planning was underway.

Results and conclusions: I find that although this project followed many best practices for achieving accountable and transparent public/private partnerships, in some instances it kept unfavorable study results from public view, limiting the potential for meaningful public involvement in the planning process. Takeaway for practice: I identify the following strategies to increase transparency and accountability in large infrastructure projects, including those delivered through private-public partnerships: (1) using a clear and narrow standard for what information should be kept confidential; (2) ensuring that public officials with responsibility for project decisions and their staffs have full access to all project information, including that not made public; (3) appointing a watchdog to see that these standards are upheld; and (4) implementing a decision process that allows public input and places the burden for proving that information should remain confidential on the entity making the request.     

网络攻击效果提取和分类

针对现有工作提出的网络攻击效果比较简单、含义抽象的缺点,研究了网络攻击效果的提取和分类。首先定义原子功能作为攻击效果的基本单位,指出原子功能提取的原则,通过分析NVD漏洞数据库、Snort规则库和Lincoln实验室攻击工具三个攻击库,最后得到五类100多个原子功能。这些原子功能可以代表大部分典型的网络攻击效果,含义明确、相互独立,且效果分类具有互斥性,可以作为网络攻击效果评估的基础,用于研究各类效果的量化评估方法,及提取各个原子功能的评估指标。     

计算机网络安全的新阶段分析与应对策略

近年来由于网络安全问题与网络犯罪等事件不断出现,网民对网络安全越来越重视,网络安全直接关系到政府、军事、保密企业等信息资料的保密不被泄露。文章结合计算机网络安全的重要性,计算机网络安全新阶段产生的问题与防御措施详细的叙述分析,提高网民使用计算机网络的安全意识能力。     

基于身份公平的匿名多接收者签密方案

针对Lal等人所提出的基于身份的多接收者签密方案中存在的暴露接收者身份信息隐私性和解密不公平的问题,应用拉格拉日插值方法,提出一种满足接收者身份匿名性和解密公平性的新的多接收者签密方案。基于双线性 Diffie-Hellman 问题和计算 Diffie-Hellman 问题,对随机模预言模型下的 IND-sMIBSC-CCA2和EUF-sMIBSC-CMA的安全性进行了证明,验证本方案具有保密性和不可否认性。     

To accept or not to accept: Referrals and the maintenance of boundaries.

Psychotherapists of all disciplines are confronted with many dilemmas in accepting or declining referrals from colleagues and patients, as well as referrals that may entail contact outside the office. The authors explore countertransference, confidentiality, boundaries, and ethics related to referral sources. Case material illustrates clinical dilemmas. Some suggestions are offered to help therapists critically examine the conscious and unconscious influences affecting their decisions about whether to accept a referral.
