摘要： Audio and image (including video) content data is watermarked by processes that take into account human perception attributes of the content. Some methods assess the input content data to discern inherent biases, and tailor the watermarking to exploit such data characteristics. Other methods make use of a trial-encoding process to determine how the watermark survives corruption—such as compression—and tailor the watermarking accordingly. A great variety of other techniques are also disclosed.

摘要： A PSD has a private key which is associated with a specific public key that is stored in the host PC. The host PC sends the PSD public key private key to the PSD. If the PSD determines that the received PSD public key corresponds to its private key, the system has determined that the expected PSD is connected to the Host system and the PSD is activated to accept postal value requests from the host PC. Additionally, a PSD state identification, such as a checksum of a PSD transaction log file stored in the host may be verified by the PSD, which also has stored therein a PSD transaction log file. In this manner the PSD verifies that the PSD has performed all transactions with the host PC sending the checksum. Methods for verifying in the PSD that the expected host PC is coupled to the PSD mirrors the two embodiments for verifying the expected PSD.
摘要翻译： PSD具有与存储在主机PC中的特定公钥相关联的私钥。主机PC将PSD公钥私钥发送到PSD。如果PSD确定接收到的PSD公钥对应于其私钥，则系统已经确定预期的PSD连接到主机系统并且PSD被激活以接受来自主机的邮件请求。此外，PSD状态识别（例如存储在主机中的PSD事务日志文件的校验和）可以由PSD验证，PSD也存储有PSD事务日志文件。以这种方式，PSD验证PSD已经执行与主机PC发送校验和的所有事务。在PSD中验证预期主机PC耦合到PSD的方法反映了两个实施例，以验证预期的PSD。

摘要： A secure environment for entering and storing information necessary to conduct encryption processes. In a computer system according to the invention, session keys, passwords, and encryption algorithms are maintained in a secure memory space such as System Management Mode (SMM) memory. In one disclosed embodiment of the invention, a user password is entered via a secure keyboard channel. The password is maintained in a secure memory space that is not accessible during normal computer operation. In addition to the user password, optional node identification information is stored in secure memory. The node identification information is appended to the user password, and both are subsequently encrypted by an encryption algorithm and encryption keys that are also stored in secure memory. Following the encryption process, the encrypted password and node identification information are communicated directly from secure memory to network interface circuitry for communication over a network. In another disclosed embodiment of the invention, data entered in a secure manner is utilized as an encryption key (or to generate an encryption key) for securely encrypting packets of data prior to communicating the data over a computer network. The encryption key data entered by the user is securely stored for use in multiple encryption processes during a communication session, thereby alleviating the overhead of repeated key renegotiation that is typically required. In addition, an encryption key that is no longer needed can be safely destroyed in secure memory without the danger of unidentified copies of the key remaining in computer memory.
摘要翻译：用于输入和存储进行加密过程所必需的信息的安全环境。在根据本发明的计算机系统中，会话密钥，密码和加密算法被保持在诸如系统管理模式（SMM）存储器之类的安全存储器空间中。在本发明的一个公开实施例中，经由安全键盘通道输入用户密码。密码保存在正常计算机操作期间无法访问的安全存储空间中。除了用户密码之外，可选节点识别信息存储在安全存储器中。节点识别信息附加到用户密码，并且随后都通过加密算法和也存储在安全存储器中的加密密钥对其进行加密。在加密过程之后，将加密密码和节点识别信息直接从安全存储器传送到网络接口电路，以便通过网络进行通信。在本发明的另一个公开的实施例中，以安全方式输入的数据被用作在通过计算机网络传送数据之前用于安全加密数据包的加密密钥（或生成加密密钥）。在通信会话期间，由用户输入的加密密钥数据被安全地存储以用于多个加密过程，从而减轻了通常需要的重复密钥重新协商的开销。此外，不再需要的加密密钥可以安全地在安全存储器中销毁，而不会存在计算机内存中剩余的密钥的不明副本的危险。

摘要： A hybrid one time pad encryption and decryption apparatus with methods for encrypting and decrypting data wherein a one time random number pad provides high security encryption. The random number sequence is encrypted using DES, RSA or other technique and embedded in the message as a function of the random pad itself. This generates an encryption message that is impervious to attempts to directly decode the message text as the message is randomly dispersed throughout a message and the message contains as much quasi-random data as text. The message is also relatively impervious to attempts to decode the cipher, as the cipher is randomly interrupted by the encrypted data.
摘要翻译：一种具有用于加密和解密数据的方法的混合一次性加密和解密装置，其中一次随机数字键盘提供高安全性加密。随机数序列使用DES，RSA或其他技术进行加密，并作为随机填充本身的函数嵌入在消息中。这产生一个加密消息，该消息在消息随机分散在整个消息中时不能直接解码消息文本，并且该消息包含与文本一样多的准随机数据。当加密数据随机中断密码时，该消息对于解码密码的尝试也是相对不透明的。

摘要： An apparatus and methods for facilitating an encryption process for use in systems employing cryptography based security, removes unnecessary data relating to encryption keys prior to storing the data after receipt of the encrypted information from a sender. Encrypted data, such as message data for multiple recipients, is analyzed to determine whether encryption related data for other recipients may be removed and/or whether a preferred encrypting process was used. In one embodiment, the apparatus and method also determines whether a non-preferred encryption process was used to encrypt encrypted data and re-encrypts the encrypted data with a different encryption process in response to detected non-preferred encryption key usage.
