No. An enterprise-grade DEMS is designed to prevent users, including top-tier administrators, from modifying, overwriting, or deleting historical audit entries once they are written. By employing append-only database architectures, the system creates a tamper-evident record built to protect activity logs against unauthorized changes or intentional manipulation.

Yes. According to the FBI’s CJIS Security Policy, the process of comprehensive tracking is essential when it comes to working with criminal justice information. It is necessary to have an  automatic record of all logins, accesses to files, changes, etc.

Gaps usually happen when digital evidence is pulled out of a secure system, like downloading a video onto a local hard drive or sharing a file through an unmanaged link. Defense attorneys look for these exact tracking gaps in court to argue that the digital evidence was exposed or mishandled, which can cause a judge to throw the file out entirely.

A cryptographic hash function converts the contents of a digital file into a unique, fixed-length alphanumeric string. Think of it as a digital fingerprint. If even a single pixel in an image or a frame in a video is altered, the resulting hash changes completely. Comparing the current hash against the ingestion hash provides definitive proof that a file has not been modified.

No. When an authorized user views a video, the platform opens the file in a strict read-only environment. The native metadata, such as the creation date and original camera settings, remains perfectly intact. The system simply logs the viewing activity as a separate historical entry without modifying the source asset.

Yes. When a case transitions to the prosecution phase, investigators or digital evidence technicians can export the complete history of an asset as a standard, human-readable document (such as a secured PDF). This report can be included directly in the discovery packet to show an unbroken chain of custody.

When a civilian uploads photos or videos using a secure link or dynamic QR code, the platform logs the entry as an external public ingestion event. The system automatically records the upload timestamp, the target case directory, and the initial file signatures, ensuring the asset is fully tracked from the moment it enters law enforcement custody.

Yes. When files are shared with external parties using secure links, the system tracks when the recipient accesses the portal, views the contents, or downloads the assets. This metadata is appended directly to the case history, providing a clear record of discovery delivery.

As a standard practice, tracking logs are retained for at least the same duration as the underlying digital evidence. Furthermore, many public safety regulations require the historical metadata and tracking trail to be archived permanently, even after the source media files have been purged under standard retention rules, to legally document how the digital evidence was handled.

Role-based access control (RBAC) determines the actions that a user can do according to their role in an organization. RBAC logs all authentication activities together with those of the user. If a user tries to open a case file beyond their authorized activities, the platform stops them and logs the activity.
