Courtroom Admissibility & Forensic Methodology

How Rocket preserves evidence integrity from first acquisition to final testimony—engineered around the Federal Rules of Evidence and the Federal Rules of Civil Procedure.

Zero-Footprint Execution

Dual-Pass Verification

FRE 902(13) & 902(14)

FRCP 26(b)(1) Proportionality

01 / EXECUTION LAYER

Zero-Footprint Memory Execution

Rocket runs ephemerally in volatile memory for the duration of each collection. Nothing is installed, no persistent services or drivers are registered, and no data is written to the custodian’s Windows registry, system files, or target storage drives. Because the host is never modified, the collection introduces no self-generated forensic artifacts that opposing experts could characterize as contamination.

No writes to the Windows registry, system files, or target storage drives

No persistent agents, services, or kernel drivers left on the endpoint

Source state preserved for independent re-examination by any expert

02 / INTEGRITY LAYER

Dual-Pass Mathematical Verification

Every collection is fingerprinted twice. A SHA-256 digest is computed at the moment of capture, then independently recomputed once the evidence lands at rest in your designated storage. Matching values prove, bit for bit, that the preserved image is identical to the data that left the source endpoint.

H = SHA-256(M)

where M is the raw, un-spoliated block data or logical volume captured from the source endpoint

Pass 1 — digest computed at acquisition, before data leaves the endpoint

Pass 2 — digest recomputed and verified at rest in your storage

Hash-chained, tamper-evident timestamps link every custody event in sequence

03 / AUTHENTICATION LAYER

FRE 902(13) & 902(14) Self-Authentication

Federal Rules of Evidence 902(13) and 902(14) permit machine-generated records and data copied from electronic devices to be authenticated through the certification of a qualified person. Rocket’s automated Chain of Custody logs and expert-witness-ready forensic reports supply the hash values, timestamps, and process documentation that certification relies on—streamlining evidence certification and reducing the need for live foundational testimony.

Expert-witness-ready forensic reports with hash values and process records

Documentation structured to support a qualified person’s written certification

04 / SCOPE LAYER

FRCP Rule 26(b)(1) Proportionality

Rule 26(b)(1) limits discovery to matter that is relevant and proportional to the needs of the case. Rocket’s targeted collection profiles let counsel define scope before acquisition begins—preserving only responsive data and avoiding the over-collection that inflates review costs and privacy exposure.
