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. 相似文献

This paper explores the way in which unruly or `deviant' women have historically been subjected to various strategies and mechanisms of control, designed to regulate and reform them back to the acceptable and appropriate standards of femininity from which they were perceived to have strayed. In particular the way in which `semi-penal' institutions were utilised for this purpose is examined. It is argued that `semi-penal' institutions such as refuges, reformatories and homes, occupied a unique position within the social control continuum, somewhere between the formal regulation of the prison and
the informal control of the domestic or communal sphere. What made them particularly unique was the way in which they managed
to combine both formal and informal methods of control in order to produce feminising regimes, aimed at reforming recalcitrant women into respectable, gendered subjects. In addition, these institutions had the effect of `widening the net' of control for women, establishing an all-encompassing system of surveillance which was at once punitive and reformative. To facilitate this analysis, five groups of women have been identified; prostitutes, criminals, the `wayward', inebriates and the `feeble-minded'. The specific methods utilised to control and reform each of these groups will be discussed along with the themes of continuity
which serve to synthesize the history of the treatment of such women.

A convergence of post-9/11 security governance practices and a dependence on extractive economies has resulted in changes to the way Canadian policing agencies classify environmental movements. We detail how the category of ‘critical infrastructure protection’ (CIP) now enables surveillance of environmentalists under the banner of national security. We examine the growth of CIP as a security category, its changing character from the Cold War to the present, and the role of threat entrepreneurs. We demonstrate that CIP networks have institutionalized collaborations between national security agencies and energy corporations, creating a petro-security apparatus that aims to suppress dissent. We conclude with reflections on what surveillance regimes driven by the petro-security apparatus mean for debates about national security and social movements. 相似文献

论视频监控的犯罪预防功能及犯罪侦查价值 总被引:1,自引:0,他引:1
各国的犯罪预防理论发展至今,已经形成了比较完善的犯罪预防体系,主要包括司法预防、社会预防和情景预防三种模式。在我国的犯罪预防体系中,向来重视司法预防和社会预防,而对情景预防关注不够,情景预防措施尚不完善。作为一种对犯罪的干预,视频监控是一种对情境犯罪的干预,研究发掘其在犯罪预防中的作用对完善犯罪预防体系具有重要意义。同时,视频监控系统在犯罪侦查方面也具有重要作用。 相似文献

Abstract: We tested the hypotheses that foraging insects can acquire human DNA from the environment and that insect‐delivered human DNA is of sufficient quantity and quality to permit standard forensic analyses. Houseflies, German cockroaches, and camel crickets were exposed to dusty surfaces and then assayed for human mitochondrial and nuclear loci by conventional and qPCR, and multiplex STR amplification. Over two experiments, 100% of insect groups and 94% of dust controls tested positive for human DNA. Of 177 individuals, 33–67% tested positive and 13 yielded quantifiable human DNA (mean = 0.022 ± 0.006 ng; mean dust control = 2.448 ± 0.960 ng); four had at least one positive allele call for one or more locus; eight others showed multiple peaks at some loci. Results imply that application to routine forensic casework is limited given current detection methodology yet demonstrate the potential use of insects as environmental samplers for human DNA. 相似文献

Because there is so much money involved in virtual worlds these days, there has been an increase in criminal activity in these worlds as well. The gaming community calls people who promote conflict “griefers”. Griefers are people who like nothing better than to kill team-mates or obstruct the game’s objectives. Griefers scam, cheat and abuse. Recently, they have begun to set up Ponzi schemes. In games that attempt to encourage complex and enduring interactions among thousands of players, “griefing” has evolved from being an isolated nuisance to a social disease. Much in the same way crime has become the real world’s social disease. Grief is turning into crime. 相似文献

在社会转型时期,由于犯罪现象本身呈现出与常态社会的极大不同,以保障人权和追诉犯罪为目的的刑事强制措施也得因之变化。监视居住是我国刑事诉讼法规定的一种强制措施,但现如今,随着其制度生存的社会根基被剥离,适用条件违反了比例原则,适用空间极其微小,以及无法破除的执行困境等废除理由的凸显和强化,它必将日渐式微并最终被废除。 相似文献
