Description

1 TARIFF THE HEALTHY USE OF FINGERPRINT DUSTING METHOD DEVICE THAT ENABLES ITS APPLICATION AS SHOWN. TECHNICAL FIELD The invention provides positive identification in forensic science, crime scene investigations, and evidence analysis. Fingerprint identification is the process applied to enable identification; fingerprint The powders used in detection ensure that the traces are detected without disappearing, application 10 ensuring that no harm is done to living things in the environment during the process and the dusting method It is related to the device that ensures its safe application. PREVIOUS TECHNIQUE Forensic science is used for positive identification in crime scene investigations and evidence analysis. Fingerprint identification is one of the important principles. However, in crime scene investigation; plastic bags, rigid duct tape, thin aluminum foil, polished wood, concrete wall, Fingerprints found on surfaces such as brick, printed glossy magazine pages Difficulties during dusting and removing the evidence 20 It is happening. One of the most common and classic methods used to identify fingerprints is, This is a dusting method. In this method, a special powder is applied to the surface where fingerprints are thought to be present. A powder is released, making the traces visible. The devices used for this process and 25 These materials are called "fingerprint dusting devices". This device ensures that the dust is evenly distributed. This ensures that the traces are distributed properly and that they can be examined without being damaged. It helps. 2 Fingerprint Dusting Tool and Method: 1. Dusting Brushes: • Working Principle: Specially designed, usually soft bristles or Magnetic brushes apply a thin layer of powder to the surface. 5 It is used to apply the powder. The brush gently distributes the powder over the marks. It makes the tracks more visible with the dust. • Brush Types: Fiber Brushes: Usually made from natural or synthetic bristles. Brushes are used to disperse dust without damaging the tracks. 10 Its soft and lightweight structure provides a delicate touch to any marks. provides. Magnetic Brushes: For applying magnetic powders. Brushes containing a metal rod are used. These brushes are used to mark the marks. It disperses the powder on the surface without direct contact. 15 • How to use: Apply the powder by brushing over the marks with light, circular motions. It spreads across the surface. Traces become visible in the areas where the dust adheres. 2. Powders (Fingerprint Powders): • Working Principle: The oils and other secretions in fingerprints leave behind 20... It traps dust particles in the trace. This makes the trace visible. Different surfaces and Various fingerprint powders are available for different conditions. • Powder Types: Carbon Powders: Black in color, usually found on light-colored surfaces. Carbon powders are used on the oily areas of fingerprints. By clinging, it makes the marks more prominent. Aluminum Powders: Commonly used on polished surfaces and glass-like materials. Used in materials. These powders are effective on light-colored surfaces. This reveals the traces. Magnetic Powders: Used with magnetic brushes. The powder is 30 It is applied to the surface by magnetic attraction and the marks are not disturbed by brushing. It is distributed. 3 Colored or Fluorescent Powders: These are used on dark-colored surfaces. The dust particles become more visible under UV light. It can shine. 3. Dusting Method: 5 • Preparation: The surface to be dusted should be prepared in a way that will not damage the markings. is examined. Dirty or dusty surfaces are not cleaned; because the cleaning process It can erase fingerprints. • Powder Application: The fingerprint brush is lightly dipped in powder, and the powder is applied to the brush... Excess dust is removed by gently shaking the brush. Then, the brush is used in a light circular motion. It is applied to the surface with movements. • Marking: Fingerprints become more distinct when dust particles adhere to the oils in the print. It becomes visible on the surface. The brush should make very light contact with the marks, otherwise... Otherwise, the tracks may be damaged. • Removing Excess Dust: After the marks become visible, remove excess dust from the surface. 15 It is cleaned by carefully blowing or with an air blower. This makes the traces more visible. It helps to make it clear. 4. Fixing and Examining the Traces: • Photography: Fingerprints are photographed once they become visible. 20 It is recorded as a document. • Removal (Transfer): Fingerprint samples are transported to the analysis laboratory. Fingerprint strips are first used to remove the traces from the surface. The strip, It is carefully applied over the traces, and the trace is transferred under the tape. This The tape is then transferred to the area to be examined. 25 • Examination: Traces obtained with tape are analyzed in a forensic science laboratory. This The analysis involves comparing the fingerprint to prints in a database and identifying the fingerprint. It includes the identification. Advantages of the Fingerprint Dusting Tool: • Easy Application: Thanks to its simplicity and portability, it can be used quickly and efficiently in the field in 30 days. It can be used effectively. • Precision: Dusting can be done on delicate surfaces without damaging the markings. 4 • High Resolution: Fingerprint details are fine, as they become more prominent with dust. Lines and details are clearly visible. Disadvantages: • Dust Spread: Incorrect or excessive use of dust can leave 5 marks on the tracks. This can lead to excessive dust accumulation and deterioration of the tracks. • Surface-Related Limitations: On some porous surfaces (such as fabric and wood) Dusting may not be effective. Detecting marks on such surfaces is more difficult. It's difficult. Fingerprint dusting method is used by forensic investigation teams to detect hidden fingerprints on surfaces. It is frequently used to identify fingerprints. With the right equipment and techniques. When applied, it makes scars more visible with a high success rate. Consequently, due to the aforementioned shortcomings and deficiencies, the relevant 15 The need for an innovation in the technical field has arisen. THE PURPOSE OF THE INVENTION The overall purpose of the invention is to create a complete system that meets the requirements mentioned above. Forensic science, in particular, eliminates disadvantages and brings some additional advantages. Positive identification in crime scene investigations and evidence analysis 5 fingerprint identification is a process applied to ensure; in fingerprint identification The powders used must be detected before the traces disappear, during application. ensuring that the living organisms in the environment are not harmed and that the dusting method is healthy It relates to the device that enables this application.
