Abstract
Systems and methods for selectively sharing of portion of unstructured data containers/documents based on security attributes or policies used to encrypt/decrypt data within the unstructured data containers using standard encryption schemes are provided herein. In some embodiments, a system includes a key generation authority to generate encryption keys based on a selected cryptographic security scheme and one or more security attributes or security policies; an encryption service to selectively encrypt one or more data subgroups using the one or more public keys and based on one or more security attributes or security policies assigned to the one or more data subgroups with the unstructured data containers; and a decryption service to decrypt the one or more data subgroups within unstructured data containers using the one or more secret keys and the one or more public keys.
