Active content is deterministically rendered in a stable format that is independent of any particular targeted environment, which the active content may subsequently be rendered to. Environmental and dynamic dependencies are removed from a specification associated with the active content for purposes of producing a stable and consistent specification for the active content. The stable and static specification is used to subsequently render the active content into the stable format for any targeted or desired environment.

Deterministic rendering of active content

Methods and apparatus, including computer program products, implementing and using techniques for document authentication. An electronic document is presented to a user. The electronic document has data representing a signed state and a current state. A disallowed difference between the signed state and the current state is detected, based on one or more rules that are associated with the electronic document. A digital signature associated with the electronic document is invalidated in response to the detecting.

Document modification detection and prevention

A system and method provide selective access to portions of digital content. A request to access a digital content item is received, the digital content item including multiple portions. Responsive to the request, multiple policies relating respectively to the multiple portions of the digital content item are identified. Access to the multiple portions of the digital content item is selectively enabled, based on the multiple policies.

Selective access to portions of digital content

Methods and apparatus, including computer program products, implementing and using techniques for signing an electronic document, including establishing an electronic signature appearance for an electronic signature, determining a bounding region on the electronic document for the display of the electronic signature appearance, at the time of signing an electronic document, previewing the electronic signature appearance in the bounding region and signing the electronic document with an electronic signature, the electronic signature associated with the electronic signature appearance. The electronic signature appearance can be configured at the time of signing the electronic document.

Dynamic preview of electronic signature appearance

A security component may be associated with a network-enabled application. The security component may access a secure store, which may include customization information, which may include one or more graphical user interface customizations defined by a user, and one or more instances of card information. The card information may specify how to authenticate a user's credentials to access a relying party (e.g., web site). The security component may initiate the display of an embedded region of a window drawn by the network-enabled application. At least a part of the appearance of the embedded region of the window may be defined according to the customization information and not by the relying party. The embedded region may provide a user interface for determining user authentication credentials. The customization information and the one or more instances of card information may not be accessible to the relying party.

Secure portable store for security skins and authentication information

A method includes receiving a request to access a digital content item, the digital content item including multiple portions. Responsive to the request, multiple policies relating respectively to the multiple portions of the digital content item are identified. Access to the multiple portions of the digital content item is selectively enabled, based on the multiple policies.

Methods and apparatus, including computer program products, implementing and using techniques for establishing trust in an electronic document. An electronic document is received. State dependent content in the electronic document is identified. The state dependent content is content that is renderable to have a several appearances. The electronic document is presented to a user, which includes disclosing the presence of any identified state dependent content in the electronic document.

Author signatures for legal purposes

A security component may be associated with a network-enabled application. The security component may initiate the display of an embedded region of a window drawn according to display information received from a relying party. The security component may define at least a portion of the appearance of the embedded region; the relying party may not define this portion. The embedded region may include customization information configured by a user, and 'Card' information received from an assertion provider, indicating how to authenticate user credentials in order to gain access to relying party restricted content. The security component may request authentication of user credentials from the assertion provider, which may be trusted by the relying party. The security component may receive an assertion token from the assertion provider indicating the credentials are authentic. The security component may forward the assertion token to the relying party to gain access to the restricted content.

System and method for trusted embedded user interface for secure payments

Methods and apparatus, including computer program products, implementing and using techniques for digital rights management. A set of content items is defined in an electronic document based on a set of rules. The rules in the set of rules are associated with one or more operations that can be performed on content items in the electronic document. The set of content items include only content items that are invariant to the operations associated with the rules in the set of rules. A representation of the content items in the set of content items is generated. An electronic document is also described.

Document digest allowing selective changes to a document

A security component may be associated with a network-enabled application. The network-enabled application may request access to restricted content from a relying party (e.g., web site). The security component associated with the network-enabled application may receive authentication policy information from the relying party and send a user's authentication credentials to an assertion provider to authenticate the credentials. The relying party may trust the assertion provider to authenticate user credentials. Upon successful authentication, the assertion provider may return an assertion token to the security component and the security component may sign the assertion token as specified in the authentication policy information. Subsequently, the security token may forward the signed assertion token to the relying party and the relying party may grant access to the restricted content.
