A system and method that automatically, transparently and securely controls software execution by identifying and classifying software, and locating a rule and associated security level for executing executable software. The security level may disallow the software's execution, restrict the execution to some extent, or allow unrestricted execution. To restrict software, a restricted access token may be computed that reduces software's access to resources, and / or removes privileges, relative to a user's normal access token. The rules that control execution for a given machine or user may be maintained in a restriction policy, e.g., locally maintained and / or in a group policy object distributable over a network. Software may be identified / classified by a hash of its content, by a digital signature, by its file system or network path, and / or by its URL zone. For software having multiple classifications, a precedence mechanism is provided to establish the applicable rule / security level.

A method of organizing a set of recognition models of known objects stored in a database of an object recognition system includes determining a classification model for each known object and grouping the classification models into multiple classification model groups. Each classification model group identifies a portion of the database that contains the recognition models of the known objects having classification models that are members of the classification model group. The method also includes computing a representative classification model for each classification model group. Each representative classification model is derived from the classification models that are members of the classification model group. When a target object is to be recognized, the representative classification models are compared to a classification model of the target object to enable selection of a subset of the recognition models of the known objects for comparison to a recognition model of the target object.

A trusted relabeler system and software is provided that allows for the simultaneous reclassification of multiple files to multiple classification labels (security domains or computer networks) through automation of the multi-person review process. Roles, used to break down the requirements of the multi-person review process, dictate what specific function a user can perform. There are three roles used: Submitter, Processor, and Reviewer. The Submitter is allowed to submit one or more documents for reclassification, while the Processor is allowed to submit one or more documents for reclassification, perform an initial review and acceptance of the document, and assign a specific Reviewer for the document. The Reviewer is allowed to perform final verification and, upon acceptance, allows the document to be reclassified appropriately. Users are assigned one or more roles and a set of source and destination classification labels inside the security policy of a specific user that are bounded (restricted) by the clearance (maximum classification) assigned to a user on the trusted operating system on which the trusted relabeler system is implemented.

An integrity seal is generated to verify that the files are not tampered with between processing by the Processor and the Reviewer. Files are upgraded or downgraded only if all processes are completed successfully.
