Passive forensics in image and video using noise features: A review

Due to present of enormous free image and video editing software on the Internet, tampering of digital images and videos have become very easy. Validating the integrity of images or videos and detecting any attempt of forgery without use of active forensic technique such as Digital Signature or Digital Watermark is a big challenge to researchers. Passive forensic techniques, unlike active techniques, do not need any preembeded information about the image or video. The proposed paper presents a comprehensive review of the recent developments in the field of digital image and video forensic using noise features. The previously existing methods of image and video forensics proved the importance of noises and encourage us for the study and perform extensive research in this field. Moreover, in this paper, forensic task cover mainly source identification and forgery detection in the image and video using noise features. Thus, various source identification and forgery detection methods using noise features are reviewed and compared in this paper for image and video. The overall objective of this paper is to give researchers a broad perspective on various aspects of image and video forensics using noise features. Conclusion part of this paper discusses about the importance of noise features and the challenges encountered by different image and video forensic method using noise features.     

浅论对侦查行为的法律监督

我国现行侦查程序缺乏有效的法律监督．检察院对侦查程序的提前介入没有立法上的保障,法院无权对侦查机关的行为进行审查和控制,犯罪嫌疑人无权与侦查机关进行平等的对话和抗争。因此,从基本理念和基本结构上对我国侦查程序进行反思,有必要限制侦查机关的权力,保护被追诉方的权利,并赋予法院对侦查行为的司法审查权。     

情报信息主导侦查机制的构成要素

侦查机关要在与犯罪作斗争的过程中赢得先机,必须建立一套长期有效的侦查机制。情报信息主导侦查机制是社会信息化的产物,是新时代适应打击违法犯罪的需要。该机制主要有六部分组成,包括情报意识、硬件设施及技术、组织管理体系、专业队伍、制度及情报信息数据库等。     

中国古代侦查谋略探源

中国古代侦查谋略极为发达,主要原因有三个方面:一是古典哲学的产生为侦查谋略的发展奠定了理论基础;二是权谋之争和频繁的战争为侦查谋略的运用提供了实践基础;三是后人对前代的学习与继承是侦查谋略发展的力量之源.     

论侦查策略的认识论和逻辑学原理

侦查策略制定的起点是观察、调查访问和侦查描述等逻辑方法。分析、综合、判断、推理等逻辑方法是从一定的人、事、物和场所等侦查策略对象到制定出侦查策略的中间环节,侦查策略措施的选择是在运用选言推理、比较等逻辑方法的基础上作出的综合决策。     

基层法官司法知识的开示

基于时中国基层司法的调查和研究,本文试图概括地总结中国基层司法中经常运用的一些在现有的法律知识体制中末于以足够重视的知识和技术,并予以初步的理论分析。本文认为,由于中国基层法院法官所处的特定制度空间（初审法院）和时空位置（中国基层社会）,他／她们所需要的知识和技巧不仅与理想型法官不同,而且与上诉审法官也不同。在这种余件下,中国基层法院法官实际上经常并非自党地创造和运用一些知识和技术。这种知识和技术有助于实用主义地解决一些实际问题,并且从现代的其他学科知识看来也具有一定的学理上的正当性,但是在有些情况下,也有可能被滥用。这种从司法实践来的知识,尽管来自基层,缺乏实践者的自我反思,但仍然具有实践意义和理论意义,需要当代中国关注现实的法学象的重视和研究。     

The acceptance,relevance and dominance of lobbying the EU Commission — a first‐time survey of the EU Commission's civil servants

Among public affairs techniques lobbying is by far the most mystifying one — at least in Europe. Lobbying comes from the Latin word ‘labium’ and means ‘entrance hall’ or ‘lounge’. Therein the essential meaning can be seen: today political decisions are not made in plenary assemblies but primarily in the pre‐political phase of balancing the various interests. Lobbying is to be understood as the ‘diverse intensive activities of social groups, chambers and companies in the political and bureaucratic vestibule’ (Beyme 1980). Modern lobbying on the EU level is an intermediary policy for the support of political decision making — even if some critics refuse to believe it. Lobbying at EU level has become a politically realistic dimension. Even if the mass media still take a very sceptical and negative view of lobbying in Brussels, based on the existing European taboo on influencing politics, an in‐depth analysis reveals various lobbies at work in EU institutions. Lobbying today is an essential part of all EU decision areas. This paper describes the functional theory approach of lobbying known as ‘cooperation as confrontation through communication’. For the first time, recipients of lobbying in the EU Commission are demonstrating their acceptance of lobbying efforts. The paper is based on the doctoral thesis ‘The acceptance, relevance and dominance of lobbying the EU Commission’ by Peter Koeppl, University of Vienna (unpublished).

谈警务技战术教师的“务”与“技”

警务技战术,是建立在良好身体素质基础上的通过训练形成的合理的克敌制胜的方法。警务技战术训练既是能力、技巧和策略的训练,也是执法水平的训练和塑造人民警察形象的训练。公安院校是培养公安后备人才、提高人民警察自身素质、加强公务队伍建设、进行警讯国际交流的重要阵地。警务技战术教学在公安院校教学中占据相当重要的地位,公安院校学员对警务技战术的学习也非常重视,同时警务技战术教师既是人民教师又是人民警察,这就要求警务技战术教师要具有较好的技战术素质,正确处理好＂务＂与＂技＂的关系。     

论“裸聊”犯罪案件的侦查

近年来,计算机网络的普及带来了犯罪形态的变化,很多传统型犯罪纷纷借助网络这一新的平台实施新型犯罪,"裸聊"犯罪就是其中之一。在短短几年内,"裸聊"扩散范围之广、危害之大已经引起了整个社会的关注。为此,公安机关只有创新侦查手段,才能有力打击此类行为,净化网络环境和社会道德风尚。     

国际刑事法院侦查程序初探

百年来,为惩治战犯、实现和平,国际社会成立了五大国际刑事法院,构建了新的法律体系。作为完整的诉讼机构,国际刑事法院设置了国际检察官与案件调查制度,产生了新型的国际侦查程序。国际侦查程序主要包括调查的启动、调查的实施、结果的处分、程序的监督等方面内容。探析国际刑事法院侦查程序对于完善国际刑事法理论与实践具有重大意义。
