摘要： An exclusive encryption system is established using multiple computing devices. The exclusive encryption system allows for the exclusion of certain plaintext (e.g., by one of the computing devices) and ciphertext (e.g., by another of the computing devices) while at the same time maintaining the privacy created by the encryption (e.g., so the other computing device cannot see the plaintext). The exclusive encryption system may be implemented as part of a serverless distributed file system with directory entries (e.g., file names or folder names) being the plaintext, or alternatively as part of other systems.

摘要： Methods and systems are described that enable protection of digital content, such as movies and the like, by making pirated copies traceable back to a unique decryption key that was utilized to decrypt the originally encrypted content. The innovative advancements do not rely on post-distribution watermarking or fingerprinting techniques, and yet intrinsically link any unauthorized copies back to a unique cryptographic key or key collection that was used when the genuine copy was reproduced. In one embodiment, digital content is provided and comprises multiple partition sets, with each partition set comprising a first partition and at least one different version of the first partition. Each partition of each partition set is uniquely marked and encrypted with a different key. Individual unique key collections are then defined to contain, for each partition set, one key that was used to encrypt a partition from the partition set and no two key collections are identical. This means that each key collection can decrypt one unique version of the digital content. This unique version of the digital content is thus inextricably tied to the key collection that was utilized to decrypt the content. Each key collection is then encrypted with a different public key associated with one of multiple content players on which the digital content is to be played. Thus, each content player is inextricably associated with one key collection, and each key collection is inextricably associated with a unique version of the digital content. The digital content and one or more key collections can then be provided to the content players. When a content player decrypts its associated key collection and uses the key collection to decrypt the digital content, the version of the digital content that is decrypted points directly to the specific content-player that was authorized to decrypt it with that key collection.
摘要翻译：描述了通过使盗版拷贝可追溯到用于解密原始加密内容的唯一解密密钥来实现数字内容（例如电影等）的保护的方法和系统。创新的进步不依赖于后期分发水印或指纹技术，而是将任何未经授权的副本本质上链接到复制真实副本时使用的唯一加密密钥或密钥集合。在一个实施例中，提供数字内容并且包括多个分区集合，其中每个分区集包括第一分区和第一分区的至少一个不同版本。每个分区集的每个分区都用不同的密钥进行唯一标记和加密。然后，将各个唯一的密钥集合定义为包含每个分区集一个用于从分区集加密分区的密钥，并且两个密钥集合是相同的。这意味着每个密钥集合可以解密数字内容的一个唯一版本。因此，数字内容的独特版本与用于解密内容的密钥集合密不可分。然后，利用与要在其上播放数字内容的多个内容播放器中的一个相关联的不同的公钥来加密每个密钥集合。因此，每个内容播放器与一个密钥集合不可分割地相关联，并且每个密钥集合与数字内容的唯一版本不可分割地相关联。然后可以向内容播放器提供数字内容和一个或多个密钥集合。当内容播放器解密其关联的密钥集合并使用密钥集合来解密数字内容时，被解密的数字内容的版本直接指向被该密钥集合被授权解密的特定内容播放器。

摘要： This document describes tools that constrain a login to a subset of access rights. In one embodiment, the tools generate a constrained password by executing a cryptographic algorithm on a user ID, general password, and one or more desired constraints. The constrained password is used in place of the general password to gain access rights that are a subset of the access rights that would be granted if the general password were used instead.

摘要： A system and method for automatically determining if a computer user is a human or an automated script. Human interactive proofs (HIPs) are currently used to deter automated registration for web services by automated computer scripts. Unfortunately, HIPs entail multiple steps (request service, receive challenge, respond to challenge) that can be burdensome. The system and method of the invention in one embodiment provides a “black-box” to potential users consisting of a challenge generator and a secret key. The challenge is generated for the user and the response can be provided as part of the service request, eliminating the need for a separate challenge from a service provider and response to the challenge.

摘要： A hierarchical identity based cryptographic system (“HIBC”) is integrated with the domain name system (“DNS”). A private key is assigned to each of the top level domain name authorities responsible for assigning the top level domain names (e.g., net, .com, etc.). The private key is generated according to an HIBC system, wherein the corresponding public key is based on the identity of the particular domain authority. When user requests a domain name from one of the top level domain name authorities, the user is issued a private key that is generated by the top level domain authority using its private key and the identity of the user according to the particular HIBC system implemented. The user's corresponding public key can be derived from the identity of the user and the public key of the top level domain name authority. Similarly, when the user adds servers and accounts to the users domain, the user can generate private keys for the servers and accounts using the users private key according to the particular HIBC system. Later, emails originating from the users domain can be authenticated by recipients using the public key associated with the top level domain name authority.
