Abstract
Common content is generated and provided to client computer systems. The common content includes encrypted portions, corresponding unencrypted portions, and decryption key identifiers that identify decryption keys for decrypting the encrypted portions. Decryption keys are provided to the client computer systems separately from the common content for decrypting portions of the common content that an associated user is authorized to view or otherwise utilize. In order to use or display the common content, the client computer systems determine for each encrypted portion in the common content whether an associated decryption key has been received. Each encrypted portion for which a decryption key is available is decrypted and displayed or otherwise utilized. For each encrypted portion for which a decryption key is not available, the unencrypted portion corresponding to the encrypted portion may be displayed or otherwise utilized.
