Custodia
Evidence Integrity Governance
Two critical capabilities in one solution
Rapid evidence triage
Discover leverage points early before opposing counsel, before trial investment, before settlement windows close. Share evidence securely while preserving chain of custody.

How digital forensic-led decision-making works
Traditional document review relies on visual inspection and basic metadata checks. Sophisticated manipulation, backdating, authorship alteration, and hidden content bypasses these approaches.
Custodia uses AI-powered forensic analysis:
01
Detection algorithms
Examine creation timestamps, modification histories, authorship chains, embedded objects
02
Counter-agent analysis
Proposes legitimate explanations for anomalies, reducing false positives
03
Risk adjudication
Flags high-risk patterns requiring human expert investigation
What we detect
Custodia generates actionable risk alerts, not definitive verdicts. Legal and compliance professionals receive evidence they can investigate further, request explanations for, or use to challenge submissions.
Impossible time stamps
Documents created before software existed, modified after submission deadlines.
Missing metadata
Suspicious absence of expected software and user fingerprints.
Inconsistent formatting
Font mismatches, style anomalies indicating manipulation.
Authorship anomalies
Creation histories incompatible with claimed authorship.
Hidden content
Embedded objects, hidden text or deletion histories revealing manipulation.
How evidence governance works
When evidence must cross organisational boundaries, shared with opposing counsel, experts, and courts, traditional methods break chain of custody. Email attachments can be altered. Cloud links can be copied. Access cannot be proven.
Confidios preserves chain of custody through:
01
Cryptographic access policies
Persist regardless of document location
02
Identity-based permissions
Control who can access evidence
03
Purpose-based restrictions
Limit use to specified operations
04
Time-bound access
Expires automatically after disclosure periods
05
Immutable audit trails
Record every access event with cryptographic proof
What audit trails prove
You can share evidence while maintaining cryptographic proof of exactly who accessed what, when, and why. This is documentation that courts and regulators accept as definitive.
Complete access history
Every person who viewed or modified documents.
Timestamps
Exact date and time of each access event.
Identity verification
Cryptographic proof of who accessed evidence.
Modification tracking
What changed, when, and by whom.
Chain of custody
Unbroken documentation from disclosure through case closure.
