Project Concept

Combate a Golpes no E-commerce com IA

🎯 A Ideia

Uma ferramenta de IA que analisa imagens de anúncios em tempo real e alerta consumidores sobre fraudes: imagens roubadas, deepfakes de produtos e design predatório.

🔴 O Problema

Consumidores, especialmente idosos e pessoas com pouco letramento digital, são vítimas de golpes visuais em e-commerce:


Imagens roubadas: Vendedores copiam fotos de produtos legítimos


Deepfakes: IA gera imagens de produtos que não existem ou exageram características


Design predatório: Cores berrantes, selos falsos de urgência, promessas irreais (“emagrece 10kg em 1 dia”)

Impacto: Prejuízos financeiros massivos e erosão da confiança no comércio digital.

💡 A Solução

Transparência Visual é uma extensão de navegador que sobrepõe um indicador visual simples em cada anúncio:


🟢 Verde: Baixo risco (anúncio legítimo)


🟡 Amarelo: Atenção (recomenda-se verificar)


🔴 Vermelho: Alto risco (forte indício de fraude)

🤖 Como a IA Funciona (3 Camadas)

1️⃣ Busca Reversa

Verifica se a mesma imagem está sendo usada por múltiplos vendedores suspeitos ou foi roubada de um site oficial.

2️⃣ Detecção de IA (SynthID + Gemini Vision)

Identifica se a imagem foi gerada ou manipulada por IA usando:


SynthID (Google DeepMind): Detecta marca d’água invisível de conteúdo gerado por IA


Gemini Vision API: Analisa artefatos visuais (dedos estranhos, reflexos irreais, texturas inconsistentes)

3️⃣ Análise de Padrões Enganosos

Detecta elementos predatórios:


Extrai texto da imagem (OCR) e procura por promessas irreais


Identifica cores berrantes, selos gigantes de urgência, cronômetros falsos


Compara qualidade da imagem de capa com fotos de avaliações

Score Final: Combina os 3 scores em uma fórmula ponderada (0-100).
