Abstract

"MéTODO E SISTEMA AUTOMATIZADO DE PRODUZIR IMAGENS CODIFICADAS". Um método automatizado de produzir imagens codificadas para incorporação dentro do documento digital é fornecido. O método compreende receber uma solicitação de um usuário para produzir uma imagem codificada. A solicitação inclui dados fornecidos pelo usuário para produzir a imagem codificada, os dados fornecidos pelo usuário incluindo indícios de autenticação fornecidos pelo usuário e/ou pelo menos um parâmetro de codificação fornecido pelo usuário. O método compreende ainda determinar se o usuário está autorizado a produzir uma imagem codificada utilizando os dados fornecidos pelo usuário. Em resposta à uma determinação de que o usuário está autorizado a produzir uma imagem codificada utilizando os dados fornecidos pelo usuário, ações de codificação são efetuadas. As ações de codificação incluem estabelecer pelo menos uma imagem de autenticação digitalizada e estabelecer um parâmetro de codificação fixado que inclui quaisquer parâmetros de codificação fornecidos pelo usuário, o conjunto de parâmetros de codificação é utilizável para codificar um ou mais de pelo menos uma imagem de autenticação digitalizada. As ações de codificação também incluem codificar uma ou mais de pelo menos uma imagem de autenticação digitalizada utilizando o parâmetro de codificação fixado para produzir uma imagem codificada final.
