Abstract

Strategies are described for validating content transferred over a communication channel using a more effective approach than heretofore provided in the art. A content registration authority is provided which registers the content disseminated by one or more content providers to one or more client devices. A client device which receives content that has been registered can securely consume the content, based on an assumption that a content provider which furnishes the content is entrusted by the content registration authority to provide the content, and without prompting a user of the client device to expressly approve the content provider. In a first solution, the content registration authority registers the content by issuing a certification stamp; in a second solution, the content registration authority registers the content by storing registration information in a central repository. The content may contain instructions which perform operations in the context of an instant messenger application.
