The Secrets Behind "Signature": 5 Things You Might Not Know About Proof (That Courts And Police Want To Tell You)

Have you ever been worried that your signature may have been forged? Or vice versa, when a lawsuit occurs, you want to reject the signature, but the process seems cumbersome, delayed, and the results are uncertain. Many people often question: In an age when fingerprint or iris scanning technology has gone so far, why is it still a big deal in court?

As a forensic consultant, I'm going to take everyone through the "tactics" and the secrets behind the pen marks. These are the reasons why the little details you overlooked became the last bulwark to destiny the lawsuit.

1.Trick to solve the game "handwriting bending" people: Why sign to the full 5 pages of paper?

When a "Specimen / Exemplar" is stored by writing in front of a Request / Witnessed Writing Officer, an investigator or court will often let you sign the same signature repeatedly on a paper with five full pages of lines.

The reason is not for satisfaction or fussy, sir, but this is a scientific "trap" to test human nature:

* The person with the intention of forging / bending the handwriting: will be able to control the bending pattern well on pages 1-2, but when you enter pages 3-4, the brain will become confused and cannot remember the "molding" pattern. The lines will start to fuse and not remain constant.

* Natural signing people: Despite fatigue, the basis of the stripes will remain the same. What has changed, only the "cold" will increase with the fatigue of the hand muscles.

"If you bend your handwriting, the lines will change because the author is confused and cannot remember the bending pattern, but if you sign by nature, the signature will start to colder with fatigue."

This allows experts to see the true "Line Quality" and screen immediately whether the sample is honest in providing evidence.

2. Secret Formula of Selection "Sample Document": + / - 3-Year Rule and a Fair Number

At the heart of the test is the so-called Collected Writing, which many people often miss by sending any document to check. We actually have iron rules to remember:

* Period rule (+ / - 3 years): Our handwriting changes with age and health, so choose documents written at the closest time to the event, such as if the "Questioned Document" indicates 1987, the sample submitted should be from 1984 to 1990 only.

* Qty 10-20 samples: A single sheet of submission cannot confirm the handwriting standard. We need 10-20 samples that come from "different days, different agendas and different transactions" to see the consistency of handwriting in everyday life.

* Focus on archives: Choose from bank documents, property transfer contracts, or government books because humans intend to sign as the most "standard," and "work time slip" or "pick-up sheet" usually doesn't work because we often sign in such a hurry that the lines are distorted from reality.

3. Maya on the "Age of Ink": What Forensic Science Still Can't Do

One of the most common false beliefs is the expectation that experts can say, "How many years did this ink write down?"

The truth is, "There is no process in the world that can prove the exact duration of writing or determine the age of ink and paper." However, as a consultant, I often suggest an equally powerful alternative: "ink type" examination.

If the documents claim to have been made in 1977, but the results of the investigation show that it was the type of ink that first began production in 2007, this is the most obvious bundle of evidence of retrodating (Anachronism), without even relying on ink age examination.

4. "Photo copy" is also detectable! (If the lines are not too sparse)

In many cases, the manuscript is lost until only a copy of the photo is left. The question is, can it be detected? The answer is "yes" if these three conditions are reached:

1. Clarity: Must not be blurred or fuzzy (high-quality scan will be very advantageous)

2. Line Detail: The signature must be complex. There is a clear line or weight. If it is a simple signature such as "Da," even if it is real, experts can give it a hard time because of too little information.

3.Enough number of samples: A lot of Specimen is required for comparison to compensate for the missing details in the copy.

However, it must be determined that the summary of the copy may only weigh "probably yes" or "probably no" (Possibility), which is inferior to the original examination.

5.Defect: Printer "DNA" and Correction Trace

Not only are signatures not lying, machines have a "unique blame." In the case of older typewriters or seals, experts look for defects, such as chipping, tilting, or the legs of a that do not ink.

These blames are like the DNA of a machine, which is very difficult to forge. On the other hand, a new computer or printer system is often printed too perfectly that there is no specific blameplay, making the results often "inconclusive."

In addition, forensic tools can detect subtle corrections, such as the case with the "Year of Limitations" correction to extend the Statute of Limitations from 1998 to 2001. Traces of line filling or ink use are clearly revealed under the proof tool, despite how smooth it originally looked.

Conclusions and last thoughts

Proof of evidence is not a matter of magic, it is a matter of "standards" and "information" to get the justice done quickly. What you should do is:

* Exclude Questioned from Specimen.

* Inform the expert the details of which document is the real one or which copy is the only one that cannot be found.

* Prepare a court review report attached to the Inspector for a clear purpose.

In the digital age, you might think that everything is easy to imitate, but believe it, the "hand weight" and "human fatigue" that appear on five sheets of paper are among the most honest evidence that AI technology has not yet been fully imitated.

Do you think that today's signature with your hands is still a reliable enough last bastion to protect your rights? If in doubt, consulting an expert to prepare a forensic example is the most important first step before going to court.
