Forensics technology has become a broad field of investigation that refers to the scientific evidence used in criminal cases. This physical evidence is comprised of scientific collection, and its analysis. There are many new aspects of this type of technology geared toward evidence or establishing facts to be used in civil or criminal proceedings.
One of the technical areas that have much to offer is digital software. Criminals and terrorists have the opportunity to use a wide variety of electronic devices in their crimes. As crimes with a digital component are on the increase, it is necessary for law enforcement to have the equipment to counter these crimes. Digital forensic software has the capacity to recover data from a computer that has been reformatted or repartitioned
Other applicable software programs:
• A program capable of wiping a hard drive clean
• A spy type of software can locate hidden partitions, plus, quickly process large hard drives, and more.
• Images can be compresses into “flat” images from floppy disks for analysis
• A “partition manager” that examines all partitions on a hard drive and can switch them around or even hide them
• A new write blocker program protects computer information more effectively than past programs
The science which interprets image content is forensic image analysis. Several companies have produced efficient equipment that cut cost and speed up investigations. The equipment is designed to do comparison photography, analysis the content, photogrammetry (using photographs to make measurements) and to authenticate the image. Through a variety of techniques, mega data, pixil aspect ratios,and errors are utilized to extract information from video, photographs and animations. This is effective even when an individual has attempted to clock the evidence.
One of the newer tools is video forensics, which is primarily the scientific examination and evaluation of multimedia evidence in legal matters. The goal of this technology is to produce an accurate picture of evidence for a judge and jury to help determine the verdict in a civil or criminal case. In addition, this technology uses processing techniques to enhance video footage, refine grainy photographs, and to enhance a particular person or an object in a video footage, plus it converts digital video into specific formats for forensic analysis. This type of work is important in solving cases for law enforcement, security, surveillance and even military operations.
Data recovery is a process used for legal purposes to retrieve data from computers. It is much more difficult to erase all the information from a computer than most people realize. The purpose of data recovery is to retrieve lost or deleted information. The mined data is done using a process of collection, analysis, and then preservation. With the successful completion of these steps the computer expert will have the lost data to present to the court. This technology may be used in civil or criminal proceedings to provide evidence for the court.
If forensic describes evidence that can be used in court, then it also must cover the technology and science necessary to provide this evidence. A forensic investigation is conducted in a lawful manner, establishing facts and evidences that have been thoroughly examined, keeping in mind the chain of custody, to be presented in a courtroom. Subdivisions that exist under this area of investigation are firewall forensics, database forensics and mobile device forensics.
