Scope & Boundaries
This section defines the normative scope of applicability for the Visual Evidence Verification Standard and explicitly identifies activities and interpretations that are outside the scope of this standard.
Scope of Applicability
VEVS defines a technical verification methodology for digital images and video, including integrity assessment, provenance indicators, internal consistency analysis, and auditability of verification processes.
Explicit Exclusions and Non-Objectives
VEVS defines methodology and reporting structure only. It does not certify implementations, determine factual truth, establish legal admissibility, or create regulatory or governing authority.
Clarification of Role
VEVS functions solely as a technical standard defining verification methodology. It is not a legal authority, certifying body, enforcement mechanism, or adjudicator. Adoption, implementation, and interpretation of VEVS remain voluntary and are the responsibility of the implementing or relying party.
Responsibility Allocation
Responsibility for misuse, misrepresentation, or overextension of VEVS outputs rests with the implementing or interpreting party. The standard itself does not assume responsibility for downstream decisions, interpretations, or outcomes.
Scope as Stated in the Standard (Section 2, Excerpts)
2.0 Scope
This standard specifies the technical requirements, processes, and terminology for verifying the authenticity and integrity of digital visual evidence. The scope of VEVS includes still images and video recordings that purport to represent real-world scenes, objects, or events.
VEVS applies to the verification methodology itself and to systems that implement this methodology. The standard does not mandate adoption, prescribe legal procedures, or define evidentiary thresholds for specific use cases. It does not guarantee correctness, truthfulness, or admissibility of evidence.
VEVS does not address non-visual data types, such as purely textual records or audio-only artifacts, except where such data is embedded within or directly associated with visual evidence. The standard assumes that annexes may provide additional definitions, scoring models, or schemas to support implementation.
2.2 Evidence Types Covered
VEVS applies to digital visual artifacts that are presented as representations of physical or real-world phenomena. Covered evidence types include, but are not limited to, raster images, encoded video streams, frame sequences extracted from video, and visual composites derived from multiple sources.
The standard applies to both original captures and derived visual artifacts, provided that the evidence is submitted for verification as a visual representation. VEVS does not assume that evidence is original, truthful, or complete; it defines methods for assessing technical properties of the submitted artifact only.
2.3 Evidence Types Excluded
VEVS does not apply to non-visual data types that are not directly associated with visual artifacts. Audio-only recordings, textual documents, numerical datasets, and sensor logs fall outside the scope of this standard unless they are embedded within, or cryptographically bound to, visual evidence as supporting material.
VEVS also does not address the authenticity of physical artifacts, witness testimony, or contextual narratives. The standard is limited to digital visual evidence and the technical processes used to evaluate such evidence.
2.7 Conformance
Conformance to VEVS requires that an implementation satisfy all applicable normative requirements expressed using the term shall within this standard. Statements expressed using the terms should, should not, or may are non-mandatory and do not define conformance obligations. Informative statements, examples, and explanatory text do not define conformance obligations.
An implementation may claim partial alignment with VEVS for internal or developmental purposes; however, such alignment shall not be represented as full conformance unless all applicable mandatory requirements are met. Conformance claims should clearly identify the version of the standard applied and any documented deviations or exclusions.
