  • Application identification and license enforcement
    Patent number: 7464270
    Abstract: The restriction of particular resources includes providing a digital signature for unauthorized resources based on a structure-related parameter of the resource. Thus, attempts at circumventing recognition of such resource will likely result in altering the overall functionality of the resource. Further, such digital signatures are encoded in a critical file required for loading of a resource, thus ensuring that the identity of the resource is considered before execution thereof. Enforcement of the resource restriction includes generating a verification signature for a resource that requests loading. The verification signature is compared to the signature coded into the critical file, and a positive match results in the resource being blocked from loading.
    Type: Grant
    Filed: July 23, 2003
    Date of Patent: December 9, 2008
    Assignee: Microsoft Corporation

  • Method and apparatus for merging user accounts from a source security domain into a target security domain
    Patent number: 5768519
    Abstract: A method is provided, in accordance with the present invention, for merging a source domain into a target domain in a network. Merging domains comprises replacing a first account identification for each account associated with the source domain by a second account identification associated with the target domain. Next, in accordance with the present invention, for each account associated with the source domain, the first account identification is added to an account security data structure storing account identifications with which the account has previously been associated when associated with a former, merged domain.
