A system and method for authenticating documents and content thereof. A counterfeit resistant document recording medium is provided, having thereon a predefined unique document identifier and at least one security feature. The recording medium is thereafter imprinted with document content, which typically varies between documents. The document content is stored in a database, indexed by an associated document identifier. The document may then be authenticated by checking the security feature and comparing the stored document content with a perceived document content. The system provides a number of opportunities for commercial exploitation, including sales of identified recording media, recording of information in a database, on-line authentication transactions, differential accounting for document validations and counterfeit identifications, imprinting devices, authentication devices, and the like. The system prevents counterfeiting of valuable documents through casual means by providing both physical and logical security.

Disclosed is a system and method that uses digital signature technology to authenticate the contents of one or more manifests located on a storage device. Each manifest contains a list of file records, where each record contains the name of a file stored on the storage device, and a signature value derived from the contents of the file. At boot time, the gaming machine first authenticates the contents of the manifest and then authenticates the contents of the files using the signature value stored in the manifest. Files are verified using the signature, as they are needed, during the boot up of the operating system and throughout normal operation. This method reduces the boot time of the gaming machine and eliminates the need to check digital signatures for each individual file or over the entire contents of a non-secure media. Similarly, a method of adding authentication ability to legacy software components without necessarily altering the legacy software components is disclosed. Introduction of a stronger authentication algorithm, or when a private key has been compromised would normally require the software component to be re-built to support the new algorithm or private / public key pair; however, a method is disclosed where algorithms and key pairs may be changed and applied to legacy software without having to re-built, re-test, re-sign, or re-submit the component to regulatory agencies for approval. Also disclosed is a system and method of establishing a trusted environment containing a gaming operating system and associated authentication module, file system drivers, and / or network drivers that may be used to in the process of authenticating contents of one or more manifests located on a storage device.

Described is a storage reports duplicate file detector that operates by receiving file records during a first scan of file system metadata. The detector computes a hash based on attributes in the record, and maintains the hash value in association with information that indicates whether a hash value corresponds to more than one file. In one implementation, the information corresponds to the amount of space wasted by duplication. The information is used to determine which hash values correspond to groups of potentially duplicate files, and eliminate non-duplicates. A second scan locates file information for each of the potentially duplicate files, and the file information is then used to determine which groups of potentially duplicate files are actually duplicate files.
