Abstract

A method and apparatus to provide an authoring tool enabling a user to create content and to selectively encrypt content is described. The encryption is designed to associate an entitlement with the content, the entitlement restricting access to the content. The system in one embodiment further includes a reading tool to access various content, the reading tool to enable an integrated reading of clear-text content and encrypted content. The system, in one embodiment, is designed to interact with a secure content service to provide a decryption key when an authorized user wishes to access the encrypted content.

Claims

1. A system comprising:

an authoring tool including an input device to enable a user to create a feed of content and to selectively encrypt at least a portion of the content as it is added to the feed of content to create clear-text content and encrypted content in the feed, the encryption including an entitlement with the feed of content, the entitlement restricting access to the encrypted content;

the authoring tool to further enable encryption of the entitlement;

a reading tool including an output device to access various content, the reading tool to enable an integrated reading of clear-text content and encrypted content in the feed;

a secure content service to compare, using a microprocessor, a profile of a reading user to the entitlement;

upon a successful authorization of the reading user, identify a filter specification specified at least in part in the encrypted entitlement;

perform at least one of actions (i) determine the encrypted content meets the filter specifications related to release time and (ii) apply the specified filter to restrict access rights of encrypted content; and

provide, using a microprocessor, a decryption key to the authorized reading user to decrypt the encrypted content.

2. The system of claim 1, wherein the entitlement comprises one or more of the following:

a static group including an authorized individual user, a dynamic group including a predefined user group having at least one user, a virtual dynamic group wherein group membership is specified by one or more characteristics in a user profile.

3. The system of claim 2, wherein the entitlement is defined by a characteristic specified in or derivable from a reader'"'"'s user profile.

4. The system of claim 2, wherein the entitlement is defined by a characteristic specified in or derivable from an author'"'"'s user profile.

5. The system of claim 1, wherein the reading tool further comprises:

a message substitution logic to insert an encryption-appropriate message for display when a non-authorized user attempts to view an encrypted entry.

6. The system of claim 1, wherein the authoring tool further comprises:

a timing logic to enable the setting of an entitlement period for a specific duration.

7. A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a microprocessor to perform the following steps:

providing a feed of content;

selecting a portion of the content to be encrypted as it is added to the feed of content;

including an entitlement with the feed of content, wherein the entitlement restricts access to the encrypted content;

encrypting the selected portion of the content;

encrypting the entitlement included with the feed of content;

accessing a portion of content not selected to be encrypted;

comparing a profile of a reading user to the entitlement;

upon a successful authorization of the reading user, identifying a filter specification specified at least in part in the encrypted entitlement;

performing at least one of actions (i) determine the encrypted content meets the filter specifications related to release time and (ii) apply the specified filter to restrict access rights of encrypted content; and

providing, using a microprocessor, a decryption key to the authorized reading user to decrypt the encrypted content.
