A system and method implemented in an interactive television system for selectively controlling the verification of interactive television content delivered to a receiver wherein a notification is provided to the receiver to identify content which can be trusted and, when trusted content is delivered to the receiver, verification procedures on the trusted content are inhibited. The notification may be delivered prior to or with the trusted content, and it may be delivered via the same transmission means as the content or by some separate delivery means. The notification may identify the trusted content positively or negatively and may use wildcards in the identification. The trusted content may be identified by its source (e.g., a trusted channel) or by reference to the content itself. The notification may contain an expiration time beyond which is no longer valid. The notification may also contain an identifier and version number so that a subsequent notification having the same identifier and a later version number will supersede the prior notification. |

DETAILED DESCRIPTION The invention comprises a system and method for controlling verification of interactive television content which may include both trusted and non-trusted information.
Trusted content may include information received from a trusted source.
Trusted content may also include information which, although received from a nontrusted source, is itself identified as trusted information.
"Trusted" is used herein to refer to content and/or sources of content for which a receiver has assurance that there is no need to verify the content.
For example, there may be assurance that the content is authentic or that the content meets a level of quality expected by the receiver, so that it is not necessary to verify these qualities.
In one embodiment, a method comprises providing a notification to an interactive television receiver to enable the receiver to skip costly verification procedures.
Interactive television content which is transmitted to the receiver is identified as trusted or non-trusted content.
Portions of the interactive television content which are nontrusted are verified using normal procedures.
Portions of the interactive television content which are trusted do not have to be verified, so verification of the trusted content is inhibited.
The identification of the trusted content may be through identification of one or more trusted sources of content, or through identification of particular pieces of content which can be trusted.
The trusted content may be identified either positively (e.
g.
, "application A is trusted,") or negatively (e.
g.
, "all applications except application B are trusted.
") The authenticity of the notification itself may be ensured by delivery through a trusted means, identification as trusted content, or verification of the notification (e.
g.
, by using a signature.
) The notification may include an expiration date after which the notification is no longer valid.
The notification may also include an identifier and a version number.
When a notification having the same identifier and a later version number than a previous notification is received, the subsequent notification supersedes the previous one
