Abstract
Objects can be extracted from data flows captured by a capture device. Each captured object can then be classified according to content. Meta-data about captured objects can be stored in a tag. In one embodiment, the present invention includes receiving a request to present a previously captured object to a user, accessing a tag associated with the requested object, the tag containing metadata related to the object, the metadata including an object signature, and verifying that the object has not been altered since capture using the object signature before presenting the object to the user.
