Falsificação de recibos com IA – Schneier on Security

Falsificação de recibos com IA

Nas últimas décadas, tornou-se cada vez mais fácil criar recibos falsos. Décadas atrás, exigia papel e impressoras especiais – lembro-me de uma empresa no Reino Unido anunciando seus serviços para pessoas que tentavam encobrir seus negócios. Então, os recibos tornaram-se computadorizados e falsificá-los exigia algumas habilidades artísticas para tornar a página realista.

Agora, a IA pode Faça tudo:

Vários recibos mostrados ao FT por plataformas de gerenciamento de despesas demonstraram a natureza realista das imagens, que incluíam rugas no papel, detalhamento de itens que combinavam com menus da vida real e assinaturas.

[…]

O aumento dessas cópias mais realistas levou as empresas a recorrer à IA para ajudar a detectar recibos falsos, já que a maioria é convincente demais para ser encontrada por revisores humanos.

O software funciona digitalizando recibos para verificar os metadados da imagem e descobrir se uma plataforma de IA a criou. No entanto, isso pode ser facilmente removido pelos usuários que tiram uma foto ou uma captura de tela da imagem.

Para combater isso, ele também considera outras informações contextuais, examinando detalhes como repetição em nomes e horários de servidores e informações mais amplas sobre a viagem do funcionário.

Mais uma corrida armamentista de segurança alimentada por IA.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).

Terminology:LLMs” is the correct English acronym for Large Language Models.
