Secure Evidence Distribution via Solid-State Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for distributing legal evidence, such as burning audio and video files to CD-ROM, DVD, or Blu-Ray disks, are time-consuming, prone to errors, and lack secure access control, leading to potential misuse and loss of metadata, and do not provide reliable audit trails.
Innovation Solution
The EvidenceKey system uses solid-state storage devices with embedded software for secure access and metadata management, allowing authorized users to download and view digital multimedia evidence with two-factor authentication and audit trail logging, eliminating the need for physical disk burning and providing secure access to metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio and video files are burned to CD-ROM, DVD, or Blu-Ray disks for distribution, then evidence can be physically distributed to authorized parties, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the mechanical process of burning physical disks with an electronic download system. Evidence is stored on a server and downloaded electronically to portable media players, eliminating the need for CD-ROM, DVD, or Blu-Ray burning processes. This substitution dramatically reduces the time and labor required for evidence distribution while maintaining secure access controls and audit trails.
2Ease of operation
If physical disks are used for evidence distribution, then evidence can be accessed offline, but secure access control and audit tracking are difficult to implement
Solution Approach 1:
The patent implements preliminary authentication and authorization before evidence is made available for download. Users must log in with credentials and receive specific download tokens that authorize access to particular evidence files. The system pre-configures portable media players with security certificates and establishes encrypted communication channels before data transfer begins. This preliminary security setup ensures that even though evidence can be accessed offline, the initial access control and audit logging are firmly established.
Solution Approach 2:
The patent implements continuous feedback mechanisms through audit logging that tracks every access attempt, download, and playback event. The system monitors user authentication, records which evidence files are accessed, and logs playback events. This feedback loop provides real-time visibility into evidence distribution and maintains security accountability, allowing administrators to track and audit all interactions with evidence files.
3Productivity
If traditional disk burning methods are used, then evidence distribution can occur without internet connectivity, but the process is prone to errors and data loss
Solution Approach 1:
The patent implements a secure electronic copying system where evidence files are transferred from the server to portable media players through controlled download processes. Unlike physical disk burning which requires manual intervention and is prone to errors, the electronic copying process is automated with built-in error checking, validation, and confirmation protocols. The system verifies data integrity during transfer and provides confirmation that evidence files have been successfully copied to the portable device.
4Loss of information
If metadata is included with evidence files, then searchability and evidential value are enhanced, but the risk of unauthorized access and metadata loss increases
Solution Approach 1:
The patent merges metadata with evidence files into integrated data packages that are downloaded and stored together on portable media players. Metadata includes search tags, timestamps, location data, and evidential annotations that enhance the value and searchability of the evidence. The merging process ensures metadata remains attached to its corresponding evidence file, preventing separation and loss. The portable media player stores both evidence and metadata in a unified structure that maintains their relationship.
Solution Approach 2:
The patent uses the portable media player as an intermediary device that securely holds both evidence files and metadata. The device acts as a trusted intermediary between the evidence server and the user, providing local secure storage that prevents unauthorized access while preserving metadata integrity. The media player enforces access controls and protects the evidence-metadata package from tampering or unauthorized copying.
