The Global Gen World

Cyber sleuthing technology has the potential to unlock valuable information in thousands of crimes that have a digital component in them. The so-called flasher boxes facilitate deeper access to data in the form of complete extraction and examination of all information contained in a wide range of cell phones. This is definitely one step ahead of criminals who are trying to hide evidence in digital devices.

The main advantage of the flasher technology over other existing methods of information retrieval is in the ease of plugging the cell phone into the box to make its entire contents spill out into the computer. Contacts, call history and even deleted images and videos are included. However, the mass of letters and numbers that are shown may make no sense but can be turned into valuable information with the right mathematical translation.

Voice Stress Analysis is a technology that uses voice-based testing to come up with a conclusion. It is based on the basic principle that the human voice contains telltale signs that will betray its speaker’s emotional state like the intent to deceive. Small and often inaudible changes in the voice occur and are visually displayed on a computer screen. It not only seeks to recognize veracity but also a range of other emotions that can be of use in a broader screening process. The lie-detector has increasingly used voice stress analysis as its software continues to be refined.

Suspects are asked several controlled questions to gauge normal vocal response levels. The real questioning that follows would reveal the computer’s interpretation of the responses immediately.

Any benefit derived from DNA technology would not be of any use unless the professionals involved in the criminal justice system or the handlers are provided training and assistance with regards to the collection and use of the DNA evidence. This would more or less include the police officers, prosecutors, defense attorneys, judges, forensic scientists, medical personnel, victim service providers, correction officers as well as the probation and parole officers.

Police officers should have the capability to collect evidence properly. Prosecutors and defense attorneys need to know how to introduce and use it successfully in court. Judges should know how to rule correctly on the evidence’s admissibility. Victim service providers and medical personnel likewise need to understand it to be more responsive to the victim’s needs.

The fundamental infrastructure support needs to be in place before any accomplishment can be hoped to achieve in increasing the analysis capacity of public crime labs. The basic processes of DNA analysis consisting of extraction, quantization, amplification and analysis require equipments and materials for it to be conducted. The process in turn, needs an information management system that is designed to automate evidence handling and casework management. This system is expected to improve the integrity and speed of evidence handling procedures while ensuring proper chain of custody.

Automated systems such as robotic DNA extraction units streamline aspects of the DNA analysis procedure that can be labor and time-intensive. It also aims to limit human error and reduce contamination. Lastly, there must be appropriate evidence storage conditions that will ensure the availability of the evidence throughout the period of investigation and justice proceedings.

There are three different procedures used simultaneously by firewalls to control data flow in a computer system. Firewalls can use a technique called Packet Filtering which evaluates small portions of data against a filter. This technique admits to the system, sections of data that are deemed acceptable while discarding others.

The Proxy Service Method lets the firewall serve as retriever between the Internet and the system where it actually obtains data from the Internet to send to the requesting system. The Stateful Inspection Approach provides that only integral parts of each segment of data are evaluated against a database of information instead of examining entire segments. Incoming information is admitted when there is satisfactory match with the attributes of the information contained within the system.

The term surveillance commonly refers to observation from a distance through the use of electronic equipment or other technological means. In French, it literally means “watching over” while the familiar “eye in the sky” remains to be the great icon of surveillance. Notwithstanding its usefulness as a tool for law enforcement and security, there is the growing concern for loss of privacy.

Surveillance may be covert or overt, but almost always involve watching over the activities of persons or groups from a position of higher authority. A whole new field of operation has been introduced through modern electronic and computer technology from the original idea of using a spy.
