Digital TraQ: A System for Archiving, Managing and Sharing Electronic Evidence

The ability to manage digital evidence has been overwhelmed by the ease of generating it. Digital evidence is burned to DVDs for submission to evidence custodians. It is necessary to pull, copy, and refile when needed by investigators, prosecutors, or the defense.

Sometimes including replacing disks. Digital files are hard to find as the search for them is primitive, but agencies copied to a server in the effort to avoid hard media. Digital TraQ helps manage the digital evidence deluge by making it easy for officers to upload all types of digital evidence, insuring file integrity, making files easily to search and share, and providing optional tools to process the evidence for analysis and presentation to court.

In minutes, officers can add and add to files. The system checks for authenticity. The investigators and prosecutors can search on the tags.

Digital Evidence in the Age of E-crime

Digital evidence is information that is stored in a format that can be relied on. Digital evidence can be found on a computer hard drive, a mobile phone, and other places. Digital evidence is now used to prosecute all types of crimes.

Critical evidence regarding the intent, location, and relationship of suspects can be found in their e-mail or mobile phone files. The serial killer who had been on the run since 1974 was finally caught in 2005 thanks to a floppy disk. Law enforcement agencies are trying to fight e-crime and collect relevant digital evidence for all crimes by incorporating the collection and analysis of digital evidence into their infrastructure.

Digital Evidence Preservation

Ensuring that digital evidence is collected, preserved, examined, or transferred during a manner that safeguards the accuracy and reliability of the evidence is a must for enforcement and forensic organizations.

Records Management

It is clear who is responsible for taking the necessary action if a specific need to create and capture records is identified. The archive should be documented if the archive is operated in-house or by a third-party service provider. One way to make sure the sender is who they say they are is using a cipher.

The method of ensuring that received and subsequently stored information is the same as the original one should be documented. The risk analysis should be done to find the best physical storage and handling options for the records. It is important to specify the relationship between the risks and the options for treatment.

Storage options should take into account access and security requirements, as well as physical storage conditions. It is possible that records that are critical for business continuity need additional protection and duplicate copies. Technology failure, fire, flood, utility failure, illness and malicious attack are some of the internal and external events that can disrupt activity.

When disruptions occur, continuity management helps to prevent them. Information may be stored for a long time, and it may be longer than the current technology. It is important to plan for the possibility of a migration process from the beginning.

A change of media, computer hardware or software is possible. Even if the need to produce electronic records in court never arises, the principles of good practice in record keeping are still worth a try. The effort and resources required to comply bring business benefits, whether the organization is in court or not, increasing organizational efficiency and improving control over information assets.

Handling Evidence

The need to handle the original evidence is being reduced by the digitising of evidence. The reduction in the handling of the original evidence reduces the chance of tampering and accidentalContamination and reduces the chain of custody requirements and overheads. The outcome of criminal prosecutions depends on evidence management.

If any of the above aspects of evidence management fail, then it can compromise the outcome of the prosecution. All but the smallest evidence storage facilities have multiple containers for different pieces of evidence. Plastic bins and bags are also seen in the default container.

Cold rooms or freezers will be provided for the preservation of evidence in larger storage facilities. Cold rooms are special environments that require less space and high-density systems are more valuable. Physical containers are usually of a size and shape that a single person can handle.

The DFORC2 Forensic Cloud

Exhibit 2 shows the disk regions generated by the Sifting Collectors diagnostic package. The green and black areas are where the files and media have never been used. Unlike traditional images, Sifting Collectors does not collect the entire disk.

Sifting Collectors discovers which parts of the disk do not contain evidence. The use of Sifting Collectors allows users to collect and analyze disk regions that may contain evidence. It allows them to get evidence quickly and start the case more quickly.

Users can go back to the original and collect the regions if they need to. The most likely reason for resistance is that Sifting Collectors requires a break from current practice. If Sifting Collectors is to achieve widespread adoption, it will be difficult to change current practice.

The number of worker nodes that can be allocated to the clusters is the second factor. DFORC2 organizes resources into a cluster manager. The cluster manager assigns computing tasks to worker nodes.

Evidence processing times will be reduced by more worker nodes. There is a limit to the number of worker nodes that can be implemented on a server, even one that is equipped with a state-of-the-art multicore microprocessor. The current prototype is complex.

i-Sight: Investigative Case Management with Digital Evidence

i-Sight software is used to manage investigations. i-Sight is a specialized investigative case management tool. Request a demo of i-Sight to find out how users are saving time, closing more cases, and reducing risk.

Digital evidence can be altered or deleted remotely, which is challenging. The investigators need to be able to prove their integrity with documentation. Documentary evidence can include other types of media, such as images, video or audio recordings, as well as written forms of proof, such as letters or wills.

The Police1 Law Enforcement Portal

Police1 is changing the way law enforcement finds news, interacts with online and research product purchases. It's the most trusted online destination for law enforcement agencies.

Forensic Software for ESI

The selection of software applications specific to a certain need has given forensic examiners the ability to provide more depth to an aspect. Current forensic software is almost described as point and click applications, compared to early forensic software which was not easy to use. The speed of electronic evidence collection is simply incredible, as compared to any previous year.

The collection of specific information from a computer system is an example of a collection. Smaller and more focused applications may be more efficient than a fully featured forensic suite. Even though there have been improvements in how digital forensic tools and techniques can be used to reduce the time required to work with evidence, there is still an underlying issue of how organization can efficiently manage the data volumes that need to be gathered and processed during a forensic investigation.

There is a need to design a storage solution that can easily adapt to the constantly growing volumes of data that need to be accessed in both real time and near real time. Storage solutions such as an EDW allow organizations to store both structured7 and unstructured8 data in a way that can be easily and dynamically adjusted to changing storage capacity requirements. It is important to remember that there is always the chance of accidentally changing the original data source when working with ESI.
