Digital Evidence Management System Selection Guide: Key Factors to Consider
Choosing the appropriate digital evidence management system is critical for law enforcement agencies. Here’s what you need to consider ensuring you select a system that meets your agency’s specific needs:
Security
As discussed above, considerations of security is of utmost importance when it comes to digital evidence management systems. That’s why it’s essential to have a platform that has the right security features.
A robust digital evidence management system uses encryption to keep data safe during transfer and storage, preventing unauthorized access. It may also include multi-factor authentication, such as an OTP sent to your email. This adds an extra layer of security by requiring more than just a password.
To ensure only authorized personnel can access specific evidence while maintaining confidentiality, it’s important to look for role-based access controls (RBAC). For example, only investigators directly involved with the case would have access to the surveillance footage, while other staff members, such as administrative personnel, would not. This prevents unnecessary exposure and helps maintain the confidentiality of the evidence.
Additionally, your DEMS should ensure the chain of custody by logging every interaction with the footage and creating an audit trail that identifies who accessed or tampered with the evidence. This way, if any unauthorized changes occur, they can be promptly detected and addressed, preserving the integrity of the evidence.
