摘要： For digital rights management (DRM) of e.g. digitally delivered music or video, a technique to make the decryption keys more secure. The technique fragments a message (song or video or other) into a number of portions, and uses a different decryption key for each portion. Each of the various keys is a function of the preceding key, in one version. In another version, each key is a function of a seed value and of the particular portion of the material with which the key is associated.

摘要： Some embodiments provide an account-based DRM system for distributing content. The system includes several devices that are associated with one particular account. The system also includes a set of DRM computers that receives a request to access a particular piece of content on the devices associated with the particular account. The DRM computer set then generates a several keys for the devices, where each particular key of each particular device allows the particular device to access the particular piece of content on the particular device. Through a network, the DRM computer set of some embodiments sends the particular piece of content and the generated keys to the devices associated with the particular account. The network is a local area network, a wide area network, or a network of networks, such as the Internet. In some of these embodiments, the DRM computer set sends the content and keys to one device (e.g., a computer), which is used to distribute the content and the key(s) to the other devices associated with the account. In some embodiments, the DRM computer set individually encrypts each key in a format that is used during its transport to its associated device and during its use on this device.

摘要： Method and apparatus for marking individual video frames of an H.264/ AVC standard compliant or equivalent digital video stream. Each video frame in a H.264/AVC video stream is conventionally divided into NAL units. There are typically a number of NAL units for each video frame. There is specified in the H.264/AVC standard the SEI (Supplemental Enhancement Information) type. This type includes the user data unregistered type, which can contain arbitrary data. In the present method and apparatus, an NAL unit of this type is provided at the beginning of each video frame, preceding the other NAL units associated with that video frame. The data contained in that special SEI unit is typically control information for downstream control of use of the video content. Examples of the type of control information are stream positioning data such as a video frame number; stream bit rate, such as normal, fast forward; decryption data, such as a decryption key or key derivation seed; and validation elements, such as a checksum or hash function value or signature.

摘要： Some embodiments of the invention provide a digital rights management (DRM) method for distributing content to users over a network. Based on a first set of diversity indicia, the method identifies a first security element for distributing a set of content to s first computer. The set of content includes one or more pieces of content. Based on a second set of diversity indicia, the method identifies a second security element for distributing the set of content to $ second computer. Based on the first security element, the method protects the set of comem for the first computer and sends the protected set of content to the first computer through the network. Based on the second security element, the method protects the set of content for the second computet and sends the protected set of content to the second computer through the network.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable media for enforcing application usage policies. As part of an application purchase transaction, the application distributor creates a unique proof of purchase receipt. This receipt can be bundled with the application and delivered to the purchaser. Each machine can maintain an authorization file that lists the users authorized to use applications on that machine. A system configured to practice the method verifies that a user is authorized to use an application on a machine based on an application proof of purchase receipt and the authorization file. If the application proof of purchase receipt and the authorization file are both valid, the system checks if the user account identifier in the receipt is contained in the authorization file. If so, the user can be considered authorized to use the application on the machine.

摘要： A method and associated apparatus for use in a data distribution process to allow an untrusted intermediary to re-encrypt data for transmission from an originator to a message receiver without revealing the data (message) or the cipher to the intermediary. This method uses a composition of two ciphers for re-encrypting the message at the intermediary, without revealing the plain text message or either cipher to the intermediary.

摘要： Method and apparatus enabled by computer (or equivalent) hardware and software for protection of content downloaded or streamed over a computer network. The content is provided to the user via streaming or downloads in encrypted form. The encryption is such that the content key decryption information is transmitted so that it itself is encrypted to be both device and session unique; the key information can be used only to extract the content decryption key for a particular session and for a particular client device, preventing any further use or copying of the content other than in that session and for that particular client. The specificity is accomplished by using a device unique identifier and session-specific anti-replay information to encrypt the content key. A typical application is Internet streaming of audio or video to consumers.

摘要： In a Digital Rights Management (DRM) system, cryptographic keys for decrypting distributed assets (such as audio or video media) are distributed using an offline (e.g., non-Internet) method for distribution of the key generation process, with an implicit authorization to use the distributed key generation process. This is used to update an asset key for use by a client such as a media player when a key formula for generating the key for decrypting an asset has been compromised, such as by hackers.

摘要： Method and apparatus to prevent hacking of encrypted audio or video content during playback. Hackers, using a debugging attachment or other tools, can illicitly access encrypted data in memory in a playback device when the data is decrypted during playback and momentarily stored in digital form. This hacking is defeated here by methodically "poisoning" the encrypted data so that it is no longer playable by a standard decoder. The poisoning involves deliberate alteration of certain bit values. On playback, the player invokes a special secure routine that provides correction of the poisoned bit values, for successful playback.
摘要翻译：播放期间防止加密音频或视频内容黑客入侵的方法和装置。使用调试附件或其他工具的黑客可以在播放过程中解密数据并立即以数字形式存储时非法访问播放设备中的加密数据。这个黑客在这里通过有条不紊地“中毒”加密的数据，使其不能被标准解码器播放，从而被击败。中毒涉及故意改变某些位值。在播放时，播放器调用特殊的安全程序，提供中毒位值的校正，以便成功播放。
