Introduction Signatures have long been used as a symbol of identity, consent, and authorisation. From banking transactions and legal agreements to passports and business contracts, signatures continue to play a vital role in everyday life. However, with the increasing cases of forgery and document fraud, verifying the authenticity of signatures ...
Introduction Crime scene evidence plays a crucial role in modern criminal investigations. Every fingerprint, bloodstain, footprint, digital device, or handwritten note collected from a scene has the potential to uncover the truth and help investigators reconstruct events accurately. However, evidence is extremely fragile. A single mistake at the crime scene ...
Introduction Forensic science has traditionally been associated with fingerprints, bloodstains, firearms, and DNA evidence collected from physical crime scenes. However, in the modern digital era, investigators are increasingly encountering a new form of invisible evidence: “digital dust.” Every online action, electronic interaction, deleted file, location ping, and even metadata fragment ...
Introduction Drones have rapidly evolved from simple recreational devices into powerful tools used in photography, agriculture, surveillance, military operations, logistics, and law enforcement. However, as drone technology grows more advanced, cybercriminals are also finding new ways to exploit its vulnerabilities. One of the most serious emerging threats is skyjacking—the unauthorised ...
Introduction Fingerprint evidence has always played a major role in criminal investigations for more than a century. Even with advanced techniques in DNA analysis, CCTV surveillance, and digital forensics, fingerprints remain one of the most reliable forms of identification. Every person has unique ridge patterns on their fingers, making fingerprints ...

They influence decisions involving financial matters, property disputes, and, in many cases, the course of justice. Most importantly, an important question arises: what if the document has been ...

Such a subtle yet powerful form of evidence is known as ghost lines. These faint impressions, often overlooked, can uncover previously written content. ...
Introduction In modern forensic science, few debates are as compelling as the comparison between touch DNA and fingerprint evidence. Both are powerful tools used to link suspects to crime scenes, yet they operate on entirely different scientific principles; more importantly, they carry different weight in courtrooms. So, which one actually ...
Introduction Fire is often seen as a perfect eraser, which is capable of reducing objects, structures, and even entire crime scenes to ashes. In popular imagination, setting a fire is the perfect way to destroy evidence and eliminate traces of a crime. But in reality, fire is far from a ...
