Integrity verification via hash (SHA-1, SHA-256, SHA-512), X.509 digital certificates and timestamping (RFC 3161).
Analysis of PDF dictionaries, revisions and incremental signatures, according to the format's internal structure (ISO 32000).
Analysis of bank contracts and onboarding dossiers: tokens, access logs, geolocation, XML/JSON files and audit trails.
Liveness detection and distinguishing a real selfie from a photo of a photo or a deepfake, supported by AI image-manipulation detection tools.
