Handwriting samples may be divided into two types: requested writing specimens and collected writing specimens. Forensic Photography: Forensic Photography is the fair and accurate recording of a scene or object, of legal interest, by a camera. b. That is the case, and being able verify origination, content, etc is vital to justice. LO1. Document examination might include alterations, obliterations, paper analysis, forgery, origin, determining authenticity, or any other questions. Conversely, there is also a light watermark that has less density of fiber in the design area, results in light and a more translucent watermark. For example, a fraudulent entry in a will may be added with ink that is visually similar but chemically different from that of the rest of the document, indicating that it was not included at the time of its original writing. Since the first edition published in 1989, there have been drastic changes in the field of forensic document examinationboth from the use of the .

Its like randomly stamping. Random Watermarks: They are randomly placed on the page. The TTI includes information such as the senders name and fax number, the recipients fax number, and the date and time of transmission. b. IR photography. Imaging instruments such as Video Spectral Comparator (VSC) use radiations of varying wavelengths to disclose writing in a different ink. T/F The first pictures the crime-scene photographer takes are the close-up photographs. Stay up-to-date with weekly communications from Robson Forensic, including substantive technical articles, safety practices across various industries and contact information from featured experts. While differentiation among inks can be accomplished by visual examination, nondestructive, and chemical tests, positive identification of the specific source of the ink (i.e., the exact pen) is unlikely. The Scientific Response and Analysis Unit provides end-to-end case support, from initial assessment of investigative or intelligence information, "hot zone" capable scientists, crime scene processing and collections, evidence examination, and courtroom testimony regarding: Pressure causes pattern diffusing over the sheet by making the pulp thinner and less denser, resulting in translucent watermarks.

Obliterations or overwritingthe blocking out of portions of writing using some opaque materialalso may be used to obscure writing or other information on the questioned document. Digital watermarks are darker and hinder the reading ability if they are used over the content of the page. All processes are the same, but with two differences; use a drier paper, and considerable high pressure. However, there will likely be evidence of laborious production, such as signs of uneven pen pressure, pen lifts, and poor line quality. Scientific examination of questioned documents [, A scientific method for forensic examination of paper [, Everything you Wanted to Know About Watermarking: From Paper Marks to Hardware Protection [, Forensic Document Examination: Fundamentals And Current Trends [Book], Forensic Document Examination: Principles And Practice [, Scientific Examination Of Documents Methods And Techniques [. An image or pattern is first created on wire and then placed over the rotating dandy roller, which presses the pattern against the wet paper on the production line similar to stamping a pad, but here no ink.

Questioned document examination consists of handwriting examination, typewriter examination, and ancillary examinations, and the effectiveness of the examiner depends greatly on courtroom presentation and training. In order to do this, it is important to photograph the stamp before making additional impressions so as to preserve its original nature (e.g., ink saturation, dirt, fibers). Any examination involving typewriting should include an evaluation of the class of typewriter, horizontal spacing, typestyle and make and model, and individual characteristics and defects. Queen bee. Digital Watermark Vs Manufacturer Watermarks Which is better? These accrediting programs ensure that forensic laboratories meet established quality standards, and employ expert forensic investigators. An UV bandpass filter mounted on the camera . b. An exemplar is an example or sample of a genuine document. No randomness is seen. Identity 3.

Ultraviolet and Infrared Luminescence Examination The wavelength of the radiations lying in the regions of ultraviolet and infrared regions when striking the erased portion of the document helps detect the erasures' sites and make the text visible. d.The jury, In digital photography, light is recorded as a specific charge on millions of tiny what? Finally, paper fiber analysis is a destructive technique that allows examiners to identify the type and quantity of fibers involved as a result of the pulping process. It is important to note, however, that not all distortions in handwriting are the result of intentional disguise. Document May Be Questioned With Respect To Its 1. Questioned document examination (QDE) is a forensic science discipline pertaining to documents that are potentially disputed in a court of law.

Difficulty/different shade in writing ink pens, pencils, typing, and print over the chemical watermark. Firstly, the design is impressed over wire mesh-like traditional watermarking. In this simple post, I am going to state why watermarks are important in the QD examination and how you can differentiate between different types of watermarks. Adobe Photoshop or similar software may be used to assess line orientation and spacing, which may be particularly useful in helping to identify anomalies or distortions in the text. Questioned documents on issues of materials used in their production. As one of the few destructive techniques employed by forensic investigators, a small piece of the document containing the ink is cut away, dissolved in solvent and analyzed. c. Shutter speed That document is a questioned document. Computer-generated documents are extremely susceptible to alterations, such as text insertion, cutting and pasting, and page substitution. They are primarily used to authenticate secure documents. This includes the forensic examination of handwriting, typewriting, office machine impressions, inks, papers, obliterations, and the recovery of latent handwriting . Watermarks also may be useful to examiners as a means of identifying the type of paper, manufacturer, and date of production. T/F Digital photography has higher resolution than film photography. Indented Writing Analysis This technique has resulted in the recovery of indented impressions on paper up to seven layers beneath the original writing, though findings may vary depending on pen pressure and paper thickness. In the first place, questioned document should be photographed promptly in order that a correct and permanent record maybe made of it and its condition. A large number of impressions should then be taken with the suspected stamp, taking care to vary the angle and pressure with which the stamp is applied, as it is unknown how the suspect applied the stamp. Identify or eliminate persons as the source of handwriting, Identify or eliminate the source of typewriting or other impression, marks, or relative evidence, and. identify and see the different instrument used in document examinations; LO6 . They are easy to make but harder to individualize. Examiners findings should reflect their systematic compilation and evaluation of all of the observed physical facts, in light of the basic rules of identification and their own experience. a.

Questioned Documents Admit it, you or someone you went to school with has tried to pass off a fake doctor's note or parent's note as real. These develop into adult drones. However, more sophisticated insertions or alterations require careful examination of the document as a whole to identify discrepancies. Questioned Documents was published in 1910, and a second edition in 1929. Worker bees are undeveloped females. Individualization, and coming up with a smaller search group can be achieved with chemical watermarks. Bees, known for their painful sting and their delicious honey, are a common sight in flower gardens. With that, the examination could lead to the individualization of a paper batch and its origin. d. White balance, What feature of a digital camera's "night mode" allows the camera to gather as much light as possible to create the image? Because the questioned document examiner (QDE) usually is not one of the original crime scene responders or the investigating detective, he or she is only responsible for the proper care and handling of evidence once it comes into the document examiner's possession. A document examiner, trying to determine if the document has been altered by chemical methods, would use which of the following? d. Disposition of items after collection must be included. This sensitive imaging process reacts to sites of microscopic damages to fibers at the surface of a document, which have been created by abrasive interactions with overlying surfaces during the act of handwriting. These chemicals replace the entrapped air in localized areas. With respect to forensic standards, ASTM describes four components to Forensic Document Examination, indicating that an examiner makes scientific examinations, comparisons, and analyses of documents in order to: The Scientific Working Group for Forensic Document Examination (SWGFDE) is another organization that develops standards in the field of forensic document examination. Information that can be extracted from the digital watermark. This article treats the historical and aesthetic aspects of still photography. The examination of questioned documents involves the non-destructive analysis of handwriting, paper, ink, impressions, etc. Like chemical watermarks, they are also embedded after the production of paper. Documents that contain indented impressions not visible to the naked eye may be recovered through the use of an Electrostatic Detection Device (EDD) and oblique lighting photography. The TYPE classification system is one tool in which investigators can classify the typestyle used in a typed document, which may lead to the identification of the make and model of the source machine. But they are not good for personal or small business use because you have to contact paper manufacturers for special orders (which are usually in bulk). Then it is made to move manually over the specific area (denser). When faced with a computer-generated document, the investigator first attempts to classify the printing process by identifying the printing technology. Font and line spacing should be examined, as discrepancies may be subtle but indicative of an alteration or addition to the original document. forger, this examination would reveal that 2 different pens were used on the document. Thus, forensic document examiners may use magnification, usually 20-40X, to better identify pen lifts and breaks, which is more often found in simulated writing, as compared to natural writing. Note taking is done after all crime-scene processing has been completed. Resolution Ink can be a liquid, paste or powder which used to produce images, text, or to make designs.

A document can be of any type i.e., handwritten or printed. characteristics of handwriting: 1) slant 2) loops 3) pressure 4) speed . Principle of development: it uses a special sheet that has a denser area where the design will impress than the rest of the paper. The first step that should be taken when investigating typewritten and machine printed documents is to determine the type(s) of printing technology involved in creating and printing the document. Disguised writing is distorted writing that is intended to mislead the reader or forensic examiner as to authorship, and is often present in questioned documents. Preliminary investigations of questioned paper documents involve testing the color, thickness, weight, weave pattern, and fiber analysis in order to determine the source of the paper. Questioned document examinations involving facsimile (fax) machines often include questions around the authenticity of a reproduced signature, concerns around whether information has been altered, added, or deleted from a document, or questions about exactly when a fax was transmitted. , this examination would reveal that 2 different pens were used on the page honey importance of photography in questioned document examination are a sight!
