Law Enforcement: Certified Evidence for Investigations and Proceedings

Forensic-grade data capture and certification to protect evidence integrity from the field to the courtroom, ensuring admissibility across jurisdictions and full compliance with international standards.

In an era where 90% of criminal cases involve digital evidence and deepfake content grows by 900% year over year, law enforcement agencies face a critical challenge: proving that photos, videos, audio recordings, and documents collected during operations are authentic and have not been altered. Human detection of high-quality deepfakes barely exceeds 24%, and courts increasingly dismiss digital evidence when its integrity cannot be independently verified. A single gap in the chain of custody can render months of investigative work inadmissible.

TrueScreen addresses this challenge by providing law enforcement officers with a forensic-grade platform to capture, verify, and certify digital evidence at the exact moment of collection. Every certified file is protected with qualified timestamps and cryptographic verification, creating an immutable record of authenticity that satisfies the most demanding international standards — from ISO/IEC 27037 to eIDAS, from INTERPOL digital forensics guidelines to the authentication requirements of the US Federal Rules of Evidence. The result is evidence that withstands legal scrutiny across borders, collected through a process that eliminates manual documentation errors and reduces the time between fieldwork and case-ready reporting.

Sector

Needs

  • Field evidence challenged in court without certified capture proving authenticity and integrity

  • Budapest Convention and UN Cybercrime Convention require evidence integrity across borders

  • ISO/IEC 27037 mandates strict protocols; manual logging extends backlogs of 1-2 years

  • Deepfake incidents up 257% in 2024 — courts need certified proof against manipulation claims

  • ACPO/NPCC four principles demand audit trails and reproducibility, costly with manual processes

Solution

TrueScreen provides law enforcement agencies with a complete evidence certification workflow that begins at the point of capture. Officers use the mobile app to acquire photos, videos, audio, GPS coordinates and screen recordings through a controlled process.

Each acquisition is automatically sealed with eIDAS-compliant timestamps, digital signature and verified metadata: operator identity, intervention context and protocol number.

The platform builds a digital chain of custody compliant with ISO/IEC 27037, from capture to archiving and court production. Certified reports are available immediately and ready for attachment to proceedings.

What gets certified

Crime scene photographs and environmental documentation

Surveillance and operational video recordings captured and certified in the field.

Audio recordings and GPS-verified evidence locations

Witness statements, field interviews, and GPS coordinates confirming exact evidence collection location.

Screen recordings and web browsing sessions

Digital content capture, online activity, websites, and social media with qualified timestamps.

Documents, physical evidence scans, and email communications

Scanned physical evidence, documents, and email communications relevant to investigations.

Expected benefits

  • Evidence withstands legal challenges, reducing case dismissal from chain-of-custody gaps

  • Cross-border evidence sharing legally defensible under Budapest and UN Conventions

  • Qualified timestamps carry legal presumption of accuracy across all EU Member States

  • Deepfake challenges countered with verifiable proof of authentic capture time and location

  • Forensic backlogs decrease as field-certified evidence arrives pre-documented and structured

  • Officers without forensic specialization collect court-ready evidence on mobile devices

FAQ: certified digital evidence for law enforcement

1) What is certified digital evidence with TrueScreen for law enforcement?
It is the transformation of photos, videos, audio, and GPS data captured in the field into legally certified evidence: qualified eIDAS timestamps, cryptographic seals, and geolocation protect every piece of content from the moment of capture.
2) What types of content can officers certify during field operations?
Photographs, videos, audio recordings, GPS coordinates, screen recordings, web browsing sessions, documents, and emails — each with a qualified timestamp and cryptographic integrity seal.
3) Does TrueScreen-certified evidence comply with international forensic standards?
Yes. The certification process is aligned with ISO/IEC 27037 for digital evidence handling, eIDAS for qualified timestamps, and supports the ACPO/NPCC four principles for digital evidence.
