GOVERNED FORENSIC REPORT

# OSHI-5 VESTIGE-VIDEO ## Forensic Video Chain of Custody Authentication Report --- **REPORT CLASSIFICATION:** Governed Forensic Documentation **SYSTEM DESIGNATION:** Oshi-5 VESTIGE-VIDEO **PATENT REFERENCE:** USPTO Application 19/571,156 **REPORT GENERATED:** 2025-04-27 (UTC) **FILE UNDER ANALYSIS:** `test-video.mov` **SCOPE LIMITATION:** *This report authenticates provenance, metadata integrity, and chain of custody only. No video content has been analyzed, interpreted, or described by this system.* --- ## ⚠️ AUTHENTICATION STATUS SUMMARY ``` ┌─────────────────────────────────────────────────────────────────┐ │ CHAIN OF CUSTODY AUTHENTICATION: ██ CONDITIONAL — INCOMPLETE │ │ CGI SCORE (AI-Generation Index): 14% — LOW SYNTHETIC SIGNAL │ │ NSI CRITICAL GAPS: 4 RED-SEVERITY FIELDS │ │ DRI INTEGRITY ANOMALIES: 0 DETECTED │ │ RULE 707 READINESS: READY (4/5 FACTORS MET) │ │ OVERALL ADMISSIBILITY POSTURE: CONDITIONAL — SEE §6 │ └─────────────────────────────────────────────────────────────────┘ ``` --- ## SECTION 1 — VIDEO PROVENANCE ASSESSMENT ### 1.1 File Identification Record | Field | Value | Status | |---|---|---| | File Name | `test-video.mov` | ✅ Present | | File Format | MOV (MPEG-4 / QuickTime Container) | ✅ Present | | File Type Signature | `qt` | ✅ Present | | File Size | 2,486,555 bytes (~2.37 MB) | ✅ Present | | Duration | 13.96 seconds (formatted: 0:13) | ✅ Present | | Time Scale | 600 ticks/second | ✅ Present | | Has Audio Stream | TRUE | ✅ Present | | Has Video Stream | TRUE | ✅ Present | | Creation Date | 2025-04-27T18:44:54.000Z | ✅ Present | | Modification Date | 2025-04-27T18:44:56.000Z | ✅ Present | ### 1.2 Temporal Provenance Analysis **Creation-to-Modification Delta:** 2 seconds This 2-second delta between `creationDate` and `modificationDate` is consistent with normal container finalization behavior in QuickTime/MOV workflows (moov atom write completion, index finalization). This gap does **not** constitute an anomaly indicator under current DRI thresholds. > **Forensic Note:** MOV/QuickTime container structure writes the `moov` atom upon file close. A sub-5-second creation-to-modification delta is a recognized artifact of this container format and is not treated as a tampering signal absent corroborating indicators. ### 1.3 Provenance Completeness Assessment Of the 18 total provenance metadata fields evaluated, **10 fields are present and confirmed**; **8 fields are absent**. Provenance completeness rate: **55.6%**. Critical provenance identifiers — originating device (camera make/model), creator identity (artist), and geospatial anchor (GPS coordinates) — are all absent. This materially limits the depth to which chain of custody can be authenticated in the forward direction. **Provenance Tier Assessment:** ``` TIER 1 — File Identity: COMPLETE ████████████ 100% TIER 2 — Temporal Anchoring: COMPLETE ████████████ 100% TIER 3 — Device Origin: ABSENT ░░░░░░░░░░░░ 0% TIER 4 — Creator Identity: ABSENT ░░░░░░░░░░░░ 0% TIER 5 — Geospatial Record: ABSENT ░░░░░░░░░░░░ 0% TIER 6 — Software Pipeline: ABSENT ░░░░░░░░░░░░ 0% TIER 7 — Rights/Attribution: ABSENT ░░░░░░░░░░░░ 0% ``` --- ## SECTION 2 — CHAIN OF CUSTODY AUTHENTICATION STATUS ### 2.1 Authentication Determination **STATUS: CONDITIONAL — CANNOT FULLY AUTHENTICATE** Chain of custody authentication for `test-video.mov` is **conditionally established** based on structural file integrity and temporal consistency. It is **not fully authenticated** due to the absence of four red-severity provenance fields that form the foundational triad of forensic video chain of custody: **device origin**, **creator identity**, and **geospatial anchoring**. ### 2.2 Authentication Factor Matrix | Authentication Factor | Present | Weight | Contribution | |---|---|---|---| | File format structural integrity | ✅ Yes | High | Positive | | Container type signature match | ✅ Yes | Medium | Positive | | Temporal record (creation/modification) | ✅ Yes | High | Positive | | Dual-stream confirmation (audio + video) | ✅ Yes | Medium | Positive | | File size consistency with duration | ✅ Yes | Medium | Positive | | Camera device identification | ❌ No | **Critical** | **Gap** | | Creator/artist identity | ❌ No | **Critical** | **Gap** | | GPS geospatial anchor | ❌ No | **Critical** | **Gap** | | Software pipeline record | ❌ No | Medium | Gap | | Resolution/encoding record | ❌ No | Medium | Gap | ### 2.3 Custody Gap Declaration This system formally declares a **Custody Gap** under VESTIGE-VIDEO Protocol §2.3. The absence of device-origin and creator-identity metadata means the file cannot be traced to a specific capture device or individual through metadata alone. External affidavit, device seizure records, or supplemental forensic evidence would be required to close this gap for evidentiary purposes. --- ## SECTION 3 — NSI FINDINGS (Null/Sparse Indicator Analysis) *NSI analysis identifies absent provenance fields, assigns severity ratings, and documents the forensic impact of each gap.* ### 3.1 RED SEVERITY FINDINGS (4) --- **NSI-001 | Artist / Creator — MISSING** - **Severity:** 🔴 RED - **Field Purpose:** Identifies the human or organizational entity responsible for creating the video file. Functions as the primary identity anchor in chain of custody. - **Forensic Impact:** Without creator identity, the file cannot be attributed to a specific individual or organization through metadata. Chain of custody is broken at the origination node. Requires supplemental extrinsic evidence for attribution. - **Evidentiary Consequence:** Admissibility challenge likely under FRE 901(a) (authentication requirement). Proponent must provide extrinsic authentication. - **Remediation Path:** Obtain sworn affidavit from purported creator; cross-reference with device capture logs; obtain custodian declaration. --- **NSI-002 | Camera Make — MISSING** - **Severity:** 🔴 RED - **Field Purpose:** Identifies the manufacturer of the capture device (e.g., Apple, Samsung, Canon). Links the file to a class of originating hardware. - **Forensic Impact:** Cannot establish hardware provenance. Prevents cross-verification with device seizure or inventory records. Eliminates device-class consistency checking. - **Evidentiary Consequence:** Inability to corroborate physical device chain of custody with metadata chain of custody. - **Remediation Path:** Physical device examination by qualified forensic examiner; device IMEI/serial correlation; carrier records if applicable. --- **NSI-003 | Camera Model — MISSING** - **Severity:** 🔴 RED - **Field Purpose:** Identifies the specific capture device model. Enables cross-reference with known device metadata profiles for authenticity validation. - **Forensic Impact:** Cannot perform device-model consistency analysis. Cannot validate that encoding parameters are consistent with claimed device class. Eliminates model-level provenance anchor. - **Evidentiary Consequence:** Same as NSI-002; compounds device provenance gap. - **Remediation Path:** Same as NSI-002. Note that combined absence of Make and Model constitutes a compound red finding. --- **NSI-004 | GPS Coordinates — MISSING** - **Severity:** 🔴 RED - **Field Purpose:** Provides geospatial anchoring of the capture event. Enables location verification and corroboration with witness statements, surveillance records, or scene documentation. - **Forensic Impact:** Cannot geospatially anchor the file to a specific location. Time-location pairing (creation timestamp + GPS) — a standard forensic authentication technique — is unavailable. - **Evidentiary Consequence:** Inability to independently corroborate claimed capture location through metadata. Location claims must be established entirely through extrinsic evidence. - **Remediation Path:** Cell tower records; carrier location data; scene witness statements; corroborating surveillance footage with confirmed location metadata. --- ### 3.2 YELLOW SEVERITY FINDINGS (4) --- **NSI-005 | Title — MISSING** - **Severity:** 🟡 YELLOW** - **Forensic Impact:** Descriptive field absent. Does not break chain of custody but reduces contextual provenance depth. Note: filename `test-video.mov` suggests a testing or draft context, which may be relevant to custody narrative. - **Remediation Path:** Custodian declaration of file identity and purpose. --- **NSI-006 | Software — MISSING** - **Severity:** 🟡 YELLOW - **Forensic Impact:** Software pipeline cannot be reconstructed from metadata. Cannot determine whether file was captured natively, processed through editing software, or transcoded. Absence of software field in a MOV container is atypical for standard iOS/macOS capture workflows, which typically embed QuickTime/AVFoundation identifiers. This absence warrants note but does not independently constitute a tampering indicator. - **Remediation Path:** Binary-level container analysis for embedded software strings; examinee disclosure of production workflow. --- **NSI-007 | Copyright — MISSING** - **Severity:** 🟡 YELLOW - **Forensic Impact:** Rights attribution absent. Relevant to provenance in intellectual property and commercial contexts. Chain of custody impact is secondary. - **Remediation Path:** Rights declaration from custodian. --- **NSI-008 | Resolution — MISSING** - **Severity:** 🟡 YELLOW - **Forensic Impact:** Cannot validate resolution consistency with claimed capture device class without this field. Note: Resolution should be determinable through deeper container parsing (video track headers); absence in surface metadata may indicate metadata stripping or non-standard export settings. - **Remediation Path:** Deep container parse of video track atom headers (`tkhd`, `vmhd`); forensic container examination tool analysis. --- ### 3.3 NSI Summary Table | ID | Field | Severity | Chain of Custody Impact | |---|---|---|---| | NSI-001 | Artist / Creator | 🔴 RED | Breaks origination node | | NSI-002 | Camera Make | 🔴 RED | Breaks device provenance | | NSI-003 | Camera Model | 🔴 RED | Breaks device provenance | | NSI-004 | GPS Coordinates | 🔴 RED | Breaks geospatial anchor | | NSI-005 | Title | 🟡 YELLOW | Reduces contextual depth | | NSI-006 | Software | 🟡 YELLOW | Pipeline unverifiable | | NSI-007 | Copyright | 🟡 YELLOW | Rights attribution absent | | NSI-008 | Resolution | 🟡 YELLOW | Encoding profile incomplete | **Red Findings:** 4 | **Yellow Findings:** 4 | **Green (No Gap):** 10 --- ## SECTION 4 — DRI INTEGRITY ANALYSIS (Digital Reliability Indicators) ### 4.1 DRI Finding Status **DRI ANOMALIES DETECTED: 0** No Digital Reliability Indicator anomalies were returned by the DRI analysis engine for `test-video.mov`. The following integrity dimensions were evaluated: | DRI Dimension | Finding | Status | |---|---|---| | Temporal consistency (creation vs. modification delta) | 2-second delta — within normal MOV finalization range | ✅ CLEAR | | Container format signature consistency | MOV/QuickTime `qt` type confirmed | ✅ CLEAR | | File size to duration ratio | ~178 KB/second — within reasonable range for compressed video | ✅ CLEAR | | Timescale validity | 600 ticks/second — standard QuickTime timescale value | ✅ CLEAR | | Dual-stream declaration consistency | Audio and video streams both declared present | ✅ CLEAR | ### 4.2 DRI Interpretive Note A clean DRI finding confirms that **no detectable integrity anomalies exist in the available metadata layer**. This finding is **constrained** by the scope of available metadata. The absence of anomalies does not constitute positive authentication; it establishes only that no indicators of post-capture modification, timestamp manipulation, or container-level inconsistency are detectable from the provided metadata set. > **Scope Limitation:** DRI analysis is performed on metadata fields only. Pixel-level, codec-level, or content-level integrity analysis falls outside the scope of this system and has not been performed. ### 4.3 CGI Score Interpretation **CGI Score: 14% — LOW AI-GENERATION SIGNAL** The Computational Generation Index score of **14%** indicates a low probability of AI-generated or synthetically originated content based on metadata-layer indicators. Specific CGI scoring factors contributing to this determination are: - Absence of known AI-platform software signatures in metadata fields - Temporal metadata consistent with organic capture workflow - File size and duration ratio consistent with camera-native compression profiles - No AI-generation watermark or provenance markers detected in metadata > **CGI Interpretive Limitation:** A 14% CGI score reflects metadata-layer analysis only. This system makes no determination regarding pixel-level synthetic generation, deepfake indicators, or generative AI content within the video stream itself. Content-level AI detection is expressly outside this system's scope. --- ## SECTION 5 — COMPLIANCE MAPPING ### 5.1 Regulatory Framework Status --- **EU AI Act Article 50 — AI-Generated Content Labeling** - **Status:** ✅ ADDRESSED - **Basis:** Creation metadata is present and structured. CGI score (14%) is computed and documented. This report constitutes a governed transparency disclosure consistent with Art. 50 labeling obligations for AI-assisted analysis systems. - **Gap Note:** If the video itself were determined to be AI-generated, downstream Art. 50 obligations would attach to the video's originator, not to this analysis system. --- **EU AI Act Article 9 — Risk Management System** - **Status:** ✅ ADDRESSED - **Basis:** Pre-Expansion Gate protocol fires before analysis initiation. Risk classification is applied prior to any inference or documentation output. This report is produced under a documented risk management framework. --- **California SB 942 — AI Transparency Act** - **Status:** ✅ ADDRESSED - **Basis:** This system's identity (Oshi-5 VESTIGE-VIDEO), methodology, and scope limitations are disclosed within this report. A governed provenance chain receipt is produced. The system does not obscure its AI-assisted nature. --- **NIST AI RMF — GOVERN Function** - **Status:** ✅ ADDRESSED - **Basis:** Pre-inference governance gate is operational. Organizational accountability for AI system outputs is documented through USPTO 19/571,156 framework. Scope limitations are affirmatively disclosed. --- **NIST AI RMF — MEASURE Function** - **Status:** ✅ ADDRESSED - **Basis:** CGI score of 14% is deterministic, reproducible, and documented with scoring methodology. Quantitative measurement of AI-generation probability is integrated into the forensic output. Error rate is calculable from methodology documentation. --- **ISO 42001 Clause 9.1 — Performance Monitoring** - **Status:** ✅ ADDRESSED - **Basis:** AGD (Automated Governance Documentation) receipt system provides continuous monitoring artifact. This report serves as an ISO 42001-compliant performance monitoring record for the analysis event. --- **FRE Rule 707 (Proposed) — AI-Generated Evidence** - **Status:** ⚠️ GAP — CONDITIONAL - **Basis:** See
