  • Patent number: 8001596
    Abstract: A method to apply a protection mechanism to a binary object includes using operating system resources to load a binary object from a storage medium along with a manifest and a digital signature. Authentication of the binary object is performed using the digital signature and the manifest is read to determine a category of protection for the binary object. The operating system selects a protection mechanism corresponding to the protection category and injects protection mechanism code, along with the binary object into a binary image on computer RAM. When the binary image is accessed, the protection mechanism executes and either allows full access and functionality to the binary object or prevents proper access and operation of the binary object. The protection mechanisms may be updated independently from the information on the storage medium.

As the program runs, the running time during the service life can be tracked by the module based on computer cycles that occur over the service life rather than on the system clock. In some embodiments, the system clock is only relied upon to track the time between service lives during which the program is asleep, thus minimizing the affect any system clock changes would have on the accuracy of the time estimate. The module adjusts the time left in the service period according to the time determinations.

  • Patent number: 7886362
    Abstract: An optical disc is authenticated by measuring physical attributes of the disc. A challenge is presented to the drive comprising the disc. The challenge includes locations on the disc to be used for authentication. The locations are determined each time the disc is to be authenticated. No restriction is placed on the locations on the medium, and no restriction is placed on the number of locations. Locations on the disc are accessed and an answer to the challenge is calculated in accordance with a physical attribute pertaining to the locations. The answer can include an angle between the locations, the physical separation between the locations, an amount of time elapsed between detection of the locations, an amount of time taken to read data between written between the locations, or a number of rotations occurring between detection of the locations. The answer is analyzed to determine the validity of the disc.

  • Publication number: 20100306860
    Abstract: A system and method for using a custom media library to secure digital media content on a computing system is disclosed. The method includes directly linking the custom media library with a copyright compliance mechanism (CCM)-enabled playback/recording application. In addition, the custom media library generates a new pathway distinct from a commonly used data pathway of the CCM-enabled playback/recording application and a media rendering subsystem of an operating system. Also, a CCM is alerted to monitor a plurality of media subsystems of the computing system. In so doing, a raw media file may be securely passed from the CCM-enabled playback/recording application via the custom media library and over the new pathway to a media subsystem of the operating system that is monitored by the CCM, such that the raw media file is rendered, playable and copyable in a secure environment.

    Abstract: A system and method of secure copy and/or playback control of a usage protected frame-based work is disclosed. The method includes accessing serial copy management system information for the usage protected frame-based work. In addition, the method validates the serial copy management system information. Copy management information of the usage protected frame-based work is also accessed. In so doing, the copy management information is utilized to determine if a secure copy/playback application is authorized to generate a copy of the usage protected frame-based work. Thus the copy management information acts as a technological measure which “effectively controls access to a work” by requiring the application of information, with the authority of the copyright owner, to gain access to the work.

  • Patent number: 7840999
    Abstract: An image processing apparatus authorizing the use thereof by carrying out user authentication prevents fraudulent use of the processor and/or a data leak due to a user's forgetting invalidation of authentication or other reason. When a user is authenticated, whether the user is authorized to use a DMFP is determined by comparing the user's input information with the information of an access-authorized person stored in the DMFP. When both information matches, a range of functions available for the user are specified, and the user is authenticated. Subsequently, for example, operation of copy setting is carried out in making setting on the DMFP. When the setting operation is over, whether authentication on the user is invalidated is determined to execute processes of copy setting, etc. In response to a trigger of invalidation of authentication on the user, the processes of copy setting, etc., are started.

  • Patent number: 7823210
    Abstract: A rights management system is described in which, subsequent to recording a media resource, client-side equipment receives and stores recording definition information (RDI). The RDI provides information that can be used to recover the keys used to decrypt the media resource. When a client device subsequently wishes to consume the media resource, it can forward the RDI to an operations center. At the operations center, a transcription module validates the client device's rights and converts the RDI into client targeted information (CTI) by recovering the keys used to decrypt the media resource. The client device receives the CTI from the transcription module and uses it to consume the media resource. The CTI has an expiration date, after which it can no longer be used.

  • Patent number: 7788504
    Abstract: Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors. However, very few SDSV sequences of data symbols can be found in multimodal codes such as Eight-to-Sixteen Modulation (ESM) utilised in DVDs. It is required to select data symbols, for encoding using a multimodal code, which are capable of forcing an encoder to produce at least one subversive sequence of code words. A possible code word for a data symbol is selected if the code word has a large absolute value of DSV and there are no alternative code words, or all alternative code words are equivalent, or all alternatives except one are ruled out by RLL rules.
