types of signature forgery
A tracing can be done by holding the model document and the questioned document up to light and using a pen to trace the lines of the model signature onto the questioned document. In essence then, while the forger creating a simulation does his best to make the prominent focal points of the signature look like the corresponding features in a genuine signature, the auto-forger goes out of his way to make them appear different. The indicators of a transmitted light tracing are similar to that of a simulation and the two are difficult to tell apart (unless the model for the tracing is located). Forgery differs from counterfeiting in that a counterfeit is a forging of coin or paper money. Such “corrections” are sloppy and make the will look unnatural and suspicious. The Fisher signature on the Stock Certificate #1 for Nefco Petroleum LLC for 100,000 shares dated 22 August 2005 (labeled as BG63) appears to be sourced from the affidavit of Ms. Fisher dated 25 October 2007, contrary to the purported date of BG63 as discussed above (Graphic Below – the signature from BG63 is in white and the signature from the affidavit is in black). Simulated forgery: This is the copying of a signature … These signature corrections are quite different than the patching that is frequently found in non-genuine signatures. These imitation signatures differ from other non-genuine signatures in that they may be legally genuine when their use has been authorized by the signature holder. A signature may be nothing more than an extension of one’s normal cursive handwriting, or it may have been personalized to such an extent that it now has few, if any, recognizable letter formations. The most common form involves forging signatures, but people can also copy handwriting to generate handwritten documents … New York classifies forgery in “degrees” based on the type of document that was forged. Extreme care should be taken by anyone, especially the court system, in evaluating the veracity of documents and signatures when no original can be produced. Further inspection will almost always reveal remarkable internal similarities to the genuine signature. These are prime examples of forensically non-genuine but legally authentic signatures. Any fraudulent signature which was executed by actually following the outline of a genuine signature with a writing instrument. Some “paperhangers” employ a light carbon tracing, difficult to see even at a short distance, as an endorsement on stolen checks. In other words, forgery usually involves faking a person’s signature for the purpose of gaining access to secured information such as a bank account or personal records. Forgery as covert operation. The third type of forgery is a tracing. Others start out with larceny in their hearts. Occasionally, the questioned document examiner is rewarded with the recovery of the used carbon paper. When you see a forged will, you often have a feeling that something “doesn’t feel right” but you can’t quite put your finger on it. The forger generates an artistic reproduction of this model. Heavier pressure is used when tracing over the model signature. (This is, of course, dependant ultimately upon court acceptance over what will undoubtedly be rigorous objections). There’s no other signature that looks like this one in our “catalog” of confirmed valid signatures. On occasion, signatures that were executed while the writing paper was on a rough surface (matte finish) contain the illusion of tremor created by simulation or tracing. The fingerprint’s universal connotation would certainly, at the very least, be a deterrent to the individual intent upon passing a forged instrument. Mechanical signatures most often are those produced without the direct aid of the human hand. This type of forgery will sometimes allow an examiner to identify who made the forgery based on the handwriting habits that are present in the forged signature. A second ink line or indentation impressed into the genuine signature by stylus or pen or other pointed implement is usually indicative of a pressure or carbon tracing. Handwriting Forgery. Existential forgery is the creation (by an adversary) of any message/signature pair $ (m, \sigma) $, where $ \sigma $ was not produced by the legitimate signer. Below is an actual court display, in a hearing in Chicago Illinois, used to compare signatures from known standards to a questioned document. If, however, the questioned signature appears to be written in a fluid manner, on a higher skill level than what is expected, the red warning flag should be waving. Often, a forger, because of an inherent high skill level in his writing, may produce a product that contains fewer “indications” of forgery than the genuine writer’s signature. All of us have wondered at one time or another why it is that we are asked to sign a document rather than simply applying an inked fingerprint to the paper as a method of identification. In regular forgery, it is impossible to imitate the unique handwriting characteristics of the writer, such as the microscopic structure of the line and an aggregate of various characteristics. Region duplication is one of the most common manipulations used for tampering digital images. The waxed paper is again rubbed briskly, melting the wax and ink composite. The limited quantity of these characteristics which appear on those occasions is such that identification of the author rarely occurs. The Types of Forgery and Discovering the Problem There are four types of possible forgery issues that the expert may discover. Those who commit forgery are often charged with the crime of fraud. New Schedule:7 & 9 December 2020Monday & WednesdaySeminar Objective:To develop certain level of awareness among participants on the various types of documents being falsified by fraudsters and their methodologies, and the visible characteristics of genuine and falsified signatures, as well as learning the process and effective methods on signature comparison. If all three criteria are met and the questioned writing is contemporaneous to the known standards that are supplied, a positive identification of authorship or non-authorship can normally be made. The properties of a questioned document that are examined include handwriting, signatures, and typewriting. Traced forgery. The forger naturally puts his greatest effort into those parts of the name that he expects to fall under the greatest scrutiny. The signature of an elderly individual may, for instance, be expected to contain tremor and hesitation. While the simulated signature will readily fail the test for genuineness when examined by a competent forensic document examiner, the forger is rarely, if ever, associated with the forgery. All Rights Reserved Websites by. False making refers to a type of forgery where paper and ink have been used to create a document from scratch, such as with a fake passport or Social Security card. Here A denotes the user whose signature method is being attacked, and C denotes the attacker. This simulation can be written with a more natural fluid manner. Types of signature forgeries: In real life a signature forgery is an event in which the forger mainly focuses on accuracy rather than fluency. Total agreement between the model and the questioned signature dictate that the questioned signature was a product of tracing. A comparison is then made between the known standards in order to establish that the writings are consistent, replete with individual handwriting habits and identifiable with each other. If he overwrites the model image with enough speed to make the forgery fluid and natural appearing, he will undoubtedly miss the model line in several areas that will then be readily discernable. Self forgery – in this type of forgery a person forges his own signature in order to deny it at a later stage. Often microscopic observation and/or infrared viewing or imaging techniques will reveal the carbon centerline. The most basic form of forgery is the unauthorized use or reproduction of another person’s signature. The signature itself will have a discernibly faded appearance and the edge of the ink line when viewed under low magnification will have a mottled look rather than sharp appearance. With an auto-forgery, the legal authenticity of the signature may be quite different than that of forensic authenticity. This paper now containing a mirror image of the genuine signature is placed over another document that is to receive the forgery. There are two general methods of perpetrating forgeries, one by the aid of tracing, the other by free-hand writing. Documents that can be the object of forgery include contracts, identification cards, and legal certificates. The forger generates an artistic reproduction of this model. This does not presuppose however, that the placement of an inked thumbprint next to a maker’s signature on a check, about to be negotiated at a check cashing counter in a grocery store, would not be a help. Extensions to entry or terminal strokes, or to lower descending portions of letters, along with corrections to embellishments, are typical of non-genuine patching. Having said that, the reader may find that these terms are occasionally used in a descriptive manner throughout this text. Many people are familiar with the term forgery, as in they have heard it used before and may have even seen it referenced on TV or in a movie. It is vital in image forensics to authenticate the digital image. Quite frequently, the “ghost” line of the carbon impression is not in register with the inked overwriting and a double line is readily apparent. Depending on his skill and amount of practice, the simulation may be quite good and bear remarkable pictorial similarity to the genuine signature. Those who commit forgery are often charged with the crime of fraud. Literary forgery. This is because we know they are genuine, even if the first letter was a bit off. Forgery of Court Documents: This involves knowingly signing the name of another without consent on a court document with the intent to mislead the court. Handwriting forgery is the duplication of someone's handwriting with the intent to create a document for fraudulent or other questionable uses. Although rarely seen today, some older style photocopying machines rely on a pre-sensitized paper coated with zinc oxide. Many people are familiar with the term forgery, as in they have heard it used before and may have even seen it referenced on TV or in a movie. This wider ink line serves to hide the carbon image better than a ballpoint pen. Transparencies of the model signature (if recovered), the impression in the carbon paper and the tracing, when aligned on an overhead projector make for an effective court demonstration. The VSC-2000 is used for magnification and image enhancement of documents. Tremor Because the creation of most forms of non-genuine signatures are little more than drawings, the pen is moving so slowly that small, sometimes microscopic changes in direction take place in what should be a fluid-looking line. Again, caution must be exercised if a second ink line is present in a genuine signature. However, on occasion a similar phenomenon can be found when NCR (National Cash Register – no carbon required) paper is employed. I am giving below a few types of signatures you should not have. These two features are frequently incorrect in the simulation. Normally a signature’s starts and stops are much more dynamic. What are the three types of forgery? Random/Blind forgery — Typically has little or no similarity to the genuine signatures. Please contact us with any questions about taking these samples. or they may require more than twelve. This may cause an emphasized blunt start or ending where the pen was placed in contact with the surface. Initial observations of an auto-forgery often appear similar to what might be expected in a simulated forgery. There are many kinds of forgery, but all are considered crimes. Now and then, the examiner will come across a derivation of this style of tracing that does not use carbon paper. Copied forgery – a copied forgery is a forgery based on a fairly precise imitation of the shape design including an attempt to imitate the space and relative location of the signature's parts. Traced forgery: In this type, the writer traces over a signature or other writing. Why does this happen? Affidavit of Forgery An affidavit of forgery is a legal document completed by a victim of fraud. On occasion there will be two or more forgers attempting to reproduce the same signature. In addition, unlike art theft and antiquities looting, art forgery generally does not involve organized crime. There are two general methods of perpetrating forgeries, one by the aid of tracing, the other by free-hand writing. They will have a slow “drawn” appearance. Close examination will reveal that this tremor is much too abundant and evenly spaced. By definition, a genuine signature is the personal mark of an individual, written by that specific individual. There can be tapered starts and stops, changes in pen pressure, and much less tremor in the moving line. In order to perform this type of examination, an examiner needs known cursive writing samples of the suspected forger in order to compare the handwriting habits in the questioned signature to the habits in the known cursive writing. The most basic form of forgery is the unauthorized use or reproduction of another person’s signature. Elements of Forgery. First degree forgery is a felony and could be punishable by anywhere from 1-2 years to 15 years in prison. Thus, the digital signature function includes the authentication function. Identity document forgery. Keeping this definition in mind, we can discuss those other “signatures” that are not genuine. • Key-only attack: C … This forgery is constructed by using a genuine signature as a model. This soft graphite will then be transferred to the receiving document in much the same manner as if carbon paper was utilized. Similar to a carbon paper tracing, the indented line tracing is produced in essentially the same manner, but does not employ any intermediate reproduction medium. The range of signature forgeries falls into the following three categories: 1. Most traditional ballpoint pen inks employ an ethylene glycol medium as the base ingredient to carry dyes, extenders, plasticizers, and other ink components. This leaves a tapered appearance at the beginnings and endings of names or letters. On these occasions, the writer is not attempting to make the signature more readable, but to make its appearance more pictorial correct. Some individuals may leave the signature alone, caring little about the mistake or imperfection, while others will simply “fix” the signature by correcting the offending portion. Of course, the document examiner faced with total agreement between a number of signatures must take care that the model signature (genuine signature) is not one of the signatures in question. Forgery involves a false document, signature, or other imitation of an object of value used with the intent to deceive another. Basics of Forgery. Although letter forms (especially the more prominent, large or beginning letters) may almost duplicate the genuine letters, proportions and height ratios will seldom be correct. No two signatures or handwritings, even from the same person, are ever totally duplicated. The answer to this riddle lies in the word “intent.” By placing a signature on a document we are implying intent on our part to agree with circumstances provided by that check, codicil, agreement, contract, etc. Using a soft-lead pencil, the reverse side of the paper containing the model signature can be shaded with the pencil’s graphite point. Types of Forgery Simple Forgery: It is very basic and is done with no attempt to follow a known sample of the handwriting or signature. The message m need not be sensical or useful in any way. Elements of Forgery. Counterfeiting. Attacks and Forgeries [GOLD88] lists the following types of attacks, in order of increasing severity.

In order to conduct a proper examination of a signature, the document examiner first needs the original document that contains the questioned signature. Forgery is commonly thought of as the white collar crime of signing another person’s name to a document, like forging signatures on a check, for instance. The product of a rubber stamp or autopen is certainly not a genuine signature but is most frequently used in a previously authorized capacity. The auto-forger, not knowing the perceptual abilities of someone that might examine the signature, incorporates gross changes to the larger, initial, or prominent letters. Start studying Handwriting Analysis. The signature that does not satisfy the requirements for genuineness must necessarily be non-genuine. There are a number of different kinds of forgery, ranging from counterfeiting to art forgery, but they are all treated as crimes under the law.In some instances, forgery is … a contrived fraud; and so, even though forged signatures-the simple and direct device-are by far the most prevalent form of documentary fraud, there is not infrequently encountered today the more intriguing form of forgery above a genuine signature. There will be little, if any, variation in the tremor and the peaks and valleys of the rough surface will be embossed into the written line. The second item needed to determine authorship is known signatures from the purported author. Because the writer does not write in his or her natural hand, it is not possible to identify the writer, but it is possible to determine if the writing was produced by tracing. The examination of signatures can answer several questions. This is the easiest type of forgery to detect because it is usually not close to the appearance of a genuine signature. This is the easiest type of forgery to detect because it is usually not close to the appearance of a genuine signature. Forgery: Types and Penalties in Pennsylvania. This process will result in a forgery that does not conform to, nor contain, the normal observable conditions that are associated with simulated or traced signatures. Contact Speckin Forensic Laboratories today. Non-genuine handwritten signatures may be generally categorized into one of four possibilities. Forgery by tracing is one of the most common and most dangerous methods of forgery. Tracing is a common type of forgery in which a document if forged using ‘transmitted light’ or ‘carbon tracing’ or ‘Indented tracing’. A signature made by employing a pen using this ink may be “transferred” to another document by using ordinary waxed paper or freezer paper. Simple Forgery: Simple forgery is just as it sounds. The closer in time the dates of the known signatures are to the date of the questioned signature, the more meaningful the examination will be. Some are more easily detectable than others. During the creation of this of non-genuine signature, the writer simply writes someone else’s name. Comparisons can be made to anonymous letters, notes and other questioned documents with known handwriting from employment files and business documents which are known to have been authored by the suspect. Signature forgery is a crime that occurs when a person signs someone else's name in order to commit fraud of decieve others. View Show abstract These documents are then aligned so as to put the genuine signature directly under the selected location for the forgery. The model signature, if recovered, may of itself contain evidence of its use in producing a tracing. Simulated forgery: This is the copying of a signature … There are four main types of forgery. This question is commonly asked when a will, a mortgage, or a contract is disputed. Wouldn’t it be just as simple to place a thumbprint on a check instead of a maker’s signature? Black propaganda — false information and material that purports to be from a source on one side of a conflict, but is actually from the opposing side. This impression is then filled in with a pen to create the appearance of the model signature. Read ahead to learn more about various types of forgery as well as the elements needed to commit the crime. (Normal Hand Forgery). In order to do an accurate comparison with either handwriting, handprinting or signatures, it is necessary to have several known, unquestioned standards. Signatures examined by the forensic document examiner for authenticity will eventually be categorized as genuine, or not genuine, if the examination leads to a definitive opinion. Aged or infirmed writers will frequently display similar patterns. If a person signs the name of the checking account holder to a check without the account holder’s permission, this is considered signature forgery. Therefore, it is often difficult to identify who forged a simulation. By associating and grouping the similar defects (when compared to the genuine signature) it may be possible to conclude and illustrate that there are indeed, two or more different forgers. Roman sculptors produced copies of Greek sculptures. Handwriting forgery is the process used by criminals to fraudulently make, alter, or write a person's signature — so that in most circumstances it appears identical with the genuine signature — with the intent of profiting from the innocent party.
