Detection of substitution-based linguistic steganography by relative frequency analysis

Linguistic steganography hides information in natural language texts. Because of the increasing in importance and quantity of natural language texts, linguistic steganography plays a more and more important role in Information Security (IS) area today. Substitution-based linguistic steganography is one of the most commonly used linguistic steganography methods, which is of considerable security and favorable simpleness. In this paper, we propose a straightforward method based on Relative Frequency Analysis (RFA), which makes use of the frequency characteristics of the testing texts (the texts being tested), to detect substitution-based linguistic steganography. We formally prove several properties about relative frequency which can be used in the detection process and propose a detection scheme. And then as an example, an existent synonym-substitution system T-Lex is examined and the detection experiment is carried out. In the experiment with pure literature texts, the accuracy, precision and recall of the detection are found to be as high as 98.64%, 97.77% and 99.55%, respectively, when the substitution count is 90, while in the experiment with balanced texts, the highest detection accuracy is 95%, which indicates that the detection scheme is promising.     

Uncovering the Iceberg: Mandating the measurement of fraud in the United Kingdom

Having regard to the impact of the credit crunch on fraud, the 19% average cuts in public spending and the wide disparities in fraud loss data, this article will argue for the mandating of fraud measurement through the introduction of legislation in the United Kingdom. The proposed statute applies to both the public and private sectors and incorporates minimum standards of measurement accuracy and the publication of findings and subsequent reduction strategies. In support of this contention this paper offers empirical evidence provided by the United States (US) Improper Payments Information Act of 2002. Further options for change are also presented including developing the role of the National Audit Office and the creation of an infrastructure for knowledge management through the sharing of best practice.     

加强党校图书馆信息服务保障工作——基于重点学科建设的视角

党校重点学科建设是一项事关党校教育事业科学发展的战略性任务,而党校图书馆作为党校教学和科研服务的文献信息中心,虽然拥有为重点学科建设提供信息服务保障的优势,但其仍然存在一些与重点学科建设所需求的信息服务不相适应的问题,如数字资源服务的内容有待拓展、整体素质有待提高等。因此,党校图书馆必须通过加强纸质文献资源建设、拓展数字资源服务内容、重构图书馆组织架构、加强人才队伍建设等途径加强信息服务保障工作,以期更好地为党校重点学科建设服务。     

国外多导仪犯罪心理测试的准确性评价与发展趋势

经过一百多年的发展,利用多导仪进行犯罪心理测试不同程度地被50多个国家所接受,但对于它的质疑并没有停止过。在对近年来国外关于准绳问题测试和隐蔽信息测试的评价与研究成果进行罗列及评价的基础上,可以发现,未来犯罪心理测试技术虽然由于其心理学原理的科学性而受到争议,并且对于测试人员的经验性要求较高,但是只要严格按照标准进行测试,其准确性仍然能够得到保障。

地理空间预测模型在以情报为导向的警务工作中的应用——以美国新泽西情报运作中心为例

构建地理空间预测模型是指根据犯罪分子有意识或无意识选择的喜好的空间信息,把成百上千个地理空间因素融合在一起,形成统计偏好相似性的地理空间模型。构建地理空间预测模型是以情报为导向的警务工作中所运用的一种新兴工作方法,是一种更为积极主动的预防犯罪的方法。     

当代警务理念变革与公安服务模式创新

社会的发展必然引起警务理念的变革。＂安全被＂与安全治理的警务思维是当代警务理念发展的新趋势。在＂义乌公安经验＂改革模式中,存在着符合当代警务理念发展趋势的一些做法,要在总结实践经验的基础上,建立＂安全被＂式的多元化安全治理目标模式。     

论经济犯罪侦查信息

侦查学基础理论关注对侦查情报的研究,但是鲜有论及侦查信息,从概念指向而言,侦查信息和侦查情报不能等同。信息时代,深入研究侦查信息已经成为一种必然趋势。在经济犯罪侦查领域,研究经济犯罪侦查信息可以帮助侦查主体培养正确的侦查思维,帮助侦查主体树立信息意识和证据意识,帮助侦查主体灵活选择侦查模式,同时还可以正确引导侦查决策。深入研究经济犯罪侦查信息理论对于经济犯罪侦查实务工作也会产生影响,其集中体现在建立和完善经济犯罪侦查协作机制、建立经济犯罪情报系统和建立经济侦查专门队伍三方面。
