Digital evidence
infrastructure, explained
Cyrify is a digital evidence infrastructure and authenticity verification API designed for teams that need tamper-evident capture, device attestation, and long‑lived digital provenance for photos, videos, and files.
The problem: deepfakes, metadata stripping, and a growing trust deficit
Digital content has never been easier to create, copy, and manipulate. Generative models, editing tools, and synthetic media make it increasingly difficult to establish what is real. Even honest captures can lose metadata through re‑compression, uploads, or messaging forwarding.
Traditional approaches depend on embedded EXIF metadata, unstructured notes, or ad‑hoc forensic analysis—creating a fragile status quo:
- Metadata is easily removed or rewritten by apps and platforms.
- Manual documentation is inconsistent and hard to audit.
- Forensic analysis is expensive, slow, and doesn't scale.
Cyrify exists to narrow this gap—not by asserting perfect authenticity, but by providing structured ways to reason about integrity, provenance, and verification limits.
Cyrify turns raw media events into cryptographic proof objects that record integrity, content authenticity signals, and chain of custody, so downstream systems can make better‑informed decisions.
Cyrify in one line: verification middleware
Cyrify sits between how content is captured and how it is later consumed or adjudicated. It provides APIs, data structures, and optional anchoring that make tamper-evident capture and digital provenance practical—without forcing you to change your storage, identity, or case management systems.
Instead of a single "verdict" flag, Cyrify exposes a structured authenticity verification API with explicit signals, statuses, and limitations, designed to be logged, audited, and re‑interpreted as policies evolve.
Three pillars of Cyrify
Integrity
Hashing, signatures, and cryptographic proof structures make post‑hoc alteration detectable. Recomputed hashes and signatures are compared with stored proof data on every verification.
Integrity checks show whether bytes have changed—not whether the original capture was honest.
Provenance
Cyrify records digital provenance data and chain of custody steps so downstream systems can trace which capture client, service, or archive touched each evidence object.
Limited to what systems can observe; not a complete map of offline activity.
Auditability
Verification outputs are deterministic, explainable, and replayable. Results can be stored alongside case files and re‑evaluated later if policies change.
Supports internal review and external oversight without exposing raw media.
Device attestation, without overclaiming
Cyrify can incorporate device attestation signals—verifying that a capture took place on a device meeting certain integrity guarantees using platform‑provided mechanisms.
These signals have clear limitations: attestation does not ensure the scene is genuine, or that no physical spoofing occurred. It provides one more data point—alongside integrity and provenance—when assessing content authenticity.
Cyrify is explicit about these boundaries: device attestation and cryptographic proof improve confidence in how content was recorded and handled, but do not equate to guarantees about reality.
What Cyrify is not
Not an AI deepfake detector
Cyrify does not label content as "real" or "fake" based on pixel‑level semantics. It focuses on verifiable structure: integrity, provenance, and attestation.
Not biometric KYC
Cyrify does not perform identity verification, liveness detection, or biometric checks. It can work alongside such systems but does not replace them.
Not a truth oracle
No combination of digital evidence infrastructure, tamper-evident capture, and device attestation can fully resolve questions of intent or offline context. Cyrify makes technical signals auditable—it doesn't "guarantee" outcomes.
Cyrify improves the technical foundation for digital provenance and chain of custody; human judgment remains essential.
Limitations and responsible use
Even with strong cryptography, tamper-evident capture and content authenticity systems have inherent limitations. Devices can be compromised, keys mishandled, and scenes staged perfectly.
Cyrify should be one component in a broader trust, safety, legal, or compliance program. Internal policies, training, and human review remain critical. Cyrify's goal is to make digital signals more trustworthy, transparent, and explainable—not to replace the people and institutions that make decisions.
