Document image security processing

Abstract:

A document image is obtained and fine-grain item-specific information within the document image is encrypted with varying levels of encryption, each encryption level associated is with a specific security access role. When the document image is presented to an end-user, the end-user's security access role determines which portions of the fine-grain item-specific information is decrypted and which portions remain encrypted, such that some portions of the document image are obfuscated from the end-user based on the end-user's security access role.
