摘要： An integrity verification process and associated apparatus to detect tampering or other alterations to computer code (software) or other computer files, and especially useful to detect tampering with code by hackers who might try to plant their own malicious code in the software. To make the verification process more robust versus hackers, each e.g., object code file to be protected is first selected using some sort of rule, then partitioned into variable length blocks or portions, the lengths varying in an unpredictable manner. Each portion has its checksum or hash value computed. An accompanying verification file is created which includes a vector for each portion including the portion's start address in memory, length, and the computed checksum or hash value. When the code is later to be run (executed) the verification file is conventionally read and each portion is verified by computing its checksum or hash value using the same algorithm as before, and comparing that to the value in the associated verification file vector. Lack of a match in the two values indicates tampering, so execution of the code can be halted.

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： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating data via a pseudo-random polymorphic tree. A server, using a seed value shared with a client device, generates a tag stream according to a byte-string algorithm. The server passes the tag stream and the data to be transmitted to the client device through a pseudo-random polymorphic tree serializer to generate a pseudo-random polymorphic tree, which the server transmits to the client device. The client device, using the same seed and byte-string algorithm, generates the same tag stream as on the server. The client passes that tag stream and the received pseudo-random polymorphic tree through a pseudo-random polymorphic tree parser to extract the data. Data to be transmitted from the server to the client device is hidden in a block of seemingly random data, which changes for different seed values. This approach obfuscates data and has low processing overhead.

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 a 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 a second computer. Based on the first security element, method protects the set of content 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 computer and sends the protected set of content to the second computer through the network.

摘要： Some embodiments of the invention provide a method for distributing content over a network. The method distributes a single media storage structure to a device (e.g., a computer, portable player, etc.) that connects to the network. The media storage structure includes first and second pieces of encrypted content. Based on whether the device is allowed to access the first piece of content, the second piece of content, or both, the method provides the device with a set of keys for decrypting the pieces of the content that the device is able to access. The provided set of keys might include one or more keys for decrypting only one of the two encrypted pieces of content. Alternatively, it might include one or more keys for decrypting both encrypted pieces of content. For instance, the selected set of keys might include a first key for decrypting the first encrypted piece and a second key for decrypting the second encrypted piece. Based on the provided set of keys, the device can then decrypt and access either one of the two pieces of content in the media storage structure or both pieces of encrypted content in the media storage structure.

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.
