This 5-year study investigated the character of Forensic Handwriting Examiners' (FHEs) authorship opinions on questioned signatures through the medium of blind validation trials. Twenty-nine thousand eight hundred and eleven authorship opinions were expressed by FHEs on trial kits comprising randomized questioned genuine signatures (written by the specimen writer), disguised signatures (written by the specimen writer) and simulated signatures (not written by the specimen writer). Results showed that, as a group, FHEs were significantly more confident at identifying writers' genuine signatures than identifying writers' disguised signatures or eliminating specimen writers from having authored simulated signatures. It is proposed that the difference in FHE confidence arises from the difficulty they have in deciding which alternative authorship explanation accounts for perceived combinations of similar and dissimilar features between specimen and questioned signatures. 相似文献

刑法中伪造信用卡犯罪中的伪造不仅包括仿制其物理外观的形式伪造,还应包括将权利人信息写入磁条介质、芯片等的内容伪造。作为伪造对象的信用卡应当是具有物理载体的实体卡片,事实上不存在对虚拟信用卡的伪造。以虚假身份骗领无对应实体卡的虚拟信用卡应视为妨害信用卡管理罪中的骗领信用卡行为;利用权利人既有实体卡信息,复制虚拟信用卡的行为系对他人信用卡信息资料的非法使用而非伪造。有关伪造信用卡犯罪刑法规定的立法原意并不包含伪造空白信用卡,伪造空白信用卡具有严重的社会危害性,理应将其纳入刑法规制范围,以保持与妨害信用卡管理罪刑法规定的协调。不能通过司法解释改变立法原意,现行刑法中伪造信用卡犯罪的伪造含义应有相应的调整。 相似文献

笔迹鉴定是一门古老的技术,其科学性和可靠性日益得到广泛认可,在司法实践中发挥着越来越重要的作用。但在笔迹鉴定实践中,常常遇到对同一笔迹的认识分歧,甚至得出完全相反鉴定意见的情况。其主要原因是对笔迹特征认识的差异。笔者认为,对笔迹特征的认识存在误区是造成分歧的根本原因。因此,认清笔迹特征的本质属性,进一步捋清笔迹特征与书写习惯之间的关系具有非常重要的现实意义。通过几个相关的基本问题进行了思考,供同行们参考。 相似文献

老年人笔迹变化的形成原因和特点 总被引:1,自引:0,他引:1
世界人口老龄化发展的历史表明,人口老龄化对人类社会生活的各个方面都会产生重大的影响。因此,研究老年人笔迹特点及其变化规律对于老年人笔迹鉴定具有理论指导意义和实用价值。根据老年人笔迹变化的形成原因和对老年人笔迹的实验统计分析,包括横向分析、纵向分析、病理性变化的分析,得出了老年人笔迹的特点。 相似文献

Document examiners are often faced with difficulties in evaluating handwriting by persons under the influence of alcohol. Although numerous articles are available on the subject of alcohol influence on handwriting quality, most of them were based on empirical data such as "few" or "increased", without any statistical evaluation. The aim of this research is to determine whether previous observations on reported effects of alcohol on handwriting are valid and to establish the predictability of observing specific effects. A total of 73 participants, who completed all steps of the experiment, were surveyed. Handwriting samples were taken before and after the consumption of alcohol. The test form, including criteria of prior studies used by document examiners, was evaluated with the help of a Olympus X-Tr stereo microscope, direct and oblique angle lighting and a video spectral comparator (VSC 2000). Measurements were done by means of digital caliper, statistics using repeated measures ANOVA, Pearson correlation, Pearson Chi square test, McNemar test and Wilcoxon signed rank test.The results revealed that the handwriting parameters such as word lengths, height of upper and lower case letters, height of ascending letter, height of descending letter, spacing between words, number of angularity, number of tremor, and number of tapered ends are all significantly increased under the effect of alcohol.It was also determined that the significant correlation between the alteration of handwriting parameters such as height of upper and lower case letters, number of angularity, number of tapered ends and the amount of alcohol. Furthermore, it does not confirm the conclusions of previous studies stating that alcohol levels are not proper indicators. Our data strongly confirms that handwriting changes can be observed at any level of alcohol.None of the alterations in handwriting can be attributed to the effects of alcohol intake alone. However, the presence of some alterations together is strongly suggestive that the person was under the influence of alcohol.First of all, the duty of handwriting examiner is to identify if the questioned and known sample are coming from the same source. Consequently, as this explanatory analysis suggests that differences between sober and intoxicated persons can be identified in handwriting, but the examiner's judgement must be proportionately cautious, keeping in mind the abnormally wide range of variation. 相似文献

论笔迹鉴定差异点的评断 总被引:1,自引:0,他引:1
书写习惯的自身同一是包含了差异的同一,而不同人书写习惯的差异则是包含了共性的非本质差异,因而在通过未知与已知笔迹比较检验来实现书写习惯的同一认定时必须科学评断差异的性质,否则同一认定鉴定意见缺乏科学可靠性。在对笔迹鉴定意见的质证中,对差异点的认识和性质的判断成为争议的焦点,而且成为评价鉴定活动是否严谨和科学,以及鉴定意见是否可以采信的主要依据之一。而今面对证据科学对笔迹鉴定意见的挑战,除严格笔迹鉴定的条件外,必须从理论上完善对笔迹鉴定差异点的评断方法,明确评断的规则,从而保证鉴定意见的科学可靠性。 相似文献

笔迹鉴定作为一门古老的技术,在国内外的司法审判历史中都扮演着重要的角色,尤其是汉字的笔迹鉴定更是在司法实践中发挥着不可替代的作用。但是在近几十年里,笔迹鉴定却面临着十分尴尬的局面:笔迹鉴定的“科学性”不断受到质疑。对此通过从有关笔迹鉴定的鉴定标准、鉴定方法、量化分析、鉴定人资质与培训考核等方面对笔迹鉴定受到质疑的原因进行分析,并从以上几方面,以及系统检验、鉴定意见的审查质证、证据补强规则等方面提出相应的解决办法。 相似文献

近几年来,民事案件中少量字检验逐年增多,由于字迹少,书写者的书写习惯反映不够充分,加上收集样本难等原因,增加了少量字检验的难度。本文作者总结了十几年从事文检鉴定的经验,剖析了少量字的特点,以及少量字的检验方法,以期同行共同研究探讨。 相似文献

笔迹鉴定在现代诉讼中日益增多,因其鉴定多依赖于"经验知识",不具有可验证的重复性,也无法接受实证的重复性检验,致使其在作为证据使用时存在一定的分歧,尤其是遗嘱笔迹因书写人死亡,其鉴定结果更富有争议。香港历经"八年"旷日持久的"世纪遗产争夺案"中的笔迹鉴定颇具典型意义。笔迹鉴定结论如何在法庭中出示以及法庭对有争议的笔迹鉴定结论如何采纳或者排除,既是一个理论问题,又是一个制度问题,还是一个价值选择问题。因此,对笔迹鉴定结论的研究与探讨成为司法鉴定制度和证据制度必须直面的带有现实意义的问题。 相似文献

Handwriting of children in early grades is studied from the viewpoint of quantitatively measuring the development of handwriting individuality. Handwriting samples of children, in grades 2–4, writing a paragraph of text in both handprinted and cursive, collected over a period of 3 years, were analyzed using two different approaches: (i) characteristics of the word “and” and (ii) entire paragraphs using an automated system. In the first approach, word characteristics were analyzed using statistical measures. In the second approach, pairs of paragraphs were compared. Both types of analysis, single word and complete writing, led to the same conclusions: (i) handwriting of each child remains relatively similar when handwriting has been just learnt and becomes markedly different from grades 3 to 4 and (ii) handwriting of different children becomes progressively more different from grades 2 to 4. The results provide strong support that handwriting becomes more individualistic with child development. 相似文献
