    Abstract: A fast and secure syntax compliant encryption schema, “locally iterative encryption,” can produce compliant ciphertext for a general syntax specification. In one implementation, an engine partitions a data stream into blocks, and encrypts each block iteratively until syntax compliance conditions are met. A system using the schema can utilize either stream ciphers or block ciphers in different modes. Locally iterative encryption methods are fast and remain at approximately the same speed even as the length of the data stream to be encrypted increases. Besides providing superior processing speed, the locally iterative encryption schema is also more robust to errors in the resulting ciphertext and in the resulting decrypted plaintext than conventional syntax compliant encryption techniques. Locally iterative encryption is secure as long as an underlying encryption cipher selected for use in the schema is secure.

    Abstract translation: 快速和安全的语法兼容加密模式“本地迭代加密”可以为通用语法规范提供符合规定的密文。 在一个实现中，引擎将数据流分割成块，并且迭代地对每个块进行加密，直到满足语法符合条件。 使用该模式的系统可以利用不同模式的流密码或块密码。 即使要加密的数据流的长度增加，本地迭代加密方法也是快速且保持大致相同的速度。 除了提供优越的处理速度之外，本地迭代加密模式对于所生成的密文中的错误以及生成的解密明文也比传统的符合法规的加密技术更加鲁棒。 只要选择用于模式的底层加密密码是安全的，本地迭代加密就是安全的。

    Abstract: A flexible framework for generating “scalable layered access” codestreams allows a bitstream architect to select the number of access types and the number of access layers within each access type. At least some of the access layers are encrypted (or scrambled). Some of the access layers may be left unencrypted or unscrambled to allow free access to those layers. The framework facilitates simultaneous access of multimedia content by different users enjoying selective decryption of different access types and different access layers. An exemplary key schema for the framework sends only one or only a few keys to an end user for a given access layer, from which decryption keys for the content can be derived by hashing and then combining under a Group Diffie-Hellman key agreement. In one implementation, only one key is sent in a license to an end user and other partial key information for Group Diffie-Hellman combination with the licensed key is included in the publicly distributed codestream.

    Abstract translation: 用于生成“可分级分层访问”码流的灵活框架允许比特流架构师选择每种访问类型中的访问类型的数量和访问层数。 至少一些接入层被加密（或加扰）。 一些访问层可以保持未加密或解扰，以允许对这些层的自由访问。 该框架便于不同用户同时访问多媒体内容，享受不同接入类型和不同接入层的选择性解密。 用于框架的示例性关键模式仅向给定访问层的最终用户发送一个或仅几个密钥，通过散列然后根据Group Diffie-Hellman密钥协议来组合内容的解密密钥。 在一个实现中，只有一个密钥在许可证中发送给最终用户，并且用于具有许可密钥的组Diffie-Hellman组合的其他部分密钥信息被包括在公开分发的码流中。

    Abstract: The described implementations relate to establishing authenticated communication between a client computing device and a service provider. In one implementation, once a registration procedure is complete, multiple authentication servers are used by a client computing device and a service provider to facilitate the establishment of an authenticated communication session. However, the authentication servers are not necessarily trusted authorities. That is, secrets of the various described devices are not revealed to each other.

    Abstract: Systems and methods for secure multimedia authentication with discrete level tamper localization are described. In these aspects, the term “discrete” means that tamper localization is at the pixel level with respect to an image or video data, or at the sample level with respect to audio data. More particularly, and in one aspect, multimedia is evaluated to determine authenticity of the multimedia. This evaluation is based on data block(s). Responsive to determining that the multimedia is not authentic, a tampered portion of the multimedia is localized by addressing each respective pixel or sample of the tampered portion.

    Abstract: A method of embedding data into an audio signal provides a data sequence for embedding in the audio signal and computes masking thresholds for the audio signal from a frequency domain transform of the audio signal. The masking thresholds correspond to subbands of the audio signal, which are obtained from a masking model used to compress the audio signal. The method applies the masking threshold to the data sequence to produce masked data sequence and inserts the masked data sequence in the audio signal to produce an embedded audio signal. A method of detecting data embedded in an audio signal analyzes the audio signal to estimate the masking threshold used in embedding the data and applies the estimated masking threshold to the audio signal to extract the embedded data.
