    摘要: A local content server system (LCS) for creating a secure environment for digital content is disclosed, which system comprises: a communications port in communication for connecting the LCS via a network to at least one Secure Electronic Content Distributor (SECD), which SECD is capable of storing a plurality of data sets, is capable of receiving a request to transfer at least one content data set, and is capable of transmitting the at least one content data set in a secured transmission; a rewritable storage medium whereby content received from outside the LCS may be stored and retrieved; a domain processor that imposes rules and procedures for content being transferred between the LCS and devices outside the LCS; and a programmable address module which can be programmed with an identification code uniquely associated with the LCS. The LCS is provided with rules and procedures for accepting and transmitting content data.

    摘要: This invention relates to security for data objects; more particularly, the present invention relates to improved security based on subliminal and supraliminal channels for data objects. In another embodiment, a method of protecting a data object comprises: steganographically encoding a subset of candidate bits in a digitized sample stream; perceptibly manipulating data in the digitized sample stream; and combining the imperceptible and perceptible data changes to create a secure/unique digital sample stream. In yet another embodiment, a method for securing a data signal comprises: preanalyzing said data signal for candidate watermark/signature bits; steganographically encoding independent data into the data signal into a subset of the candidate watermark bits, at least one time; and encoding the data signal subsequently with a perceptible technique.

    摘要: Disclosed herein are methods and systems for transmitting streams of data. The present invention also relates to generating packet watermarks and packet watermark keys. The present invention also relates to a computerized system for packaging data for transmission to a user. The system may utilize computer code to generate a bandwidth rights certificate that may include: at least one cryptographic credential; routing information for the transmission; and, optionally, a digital signature of a certificate owner; a unique identification code of a certificate owner; a certificate validity period; and pricing information for use of bandwidth. The present invention also relates to an electronic method and system for purchasing good and services by establishing an account whereby a customer is credited with a predetermined amount of bandwidth usage, and then charges are assessed against the account in an amount of bandwidth usage which corresponds to the agreed upon purchase value for the selected item.

    摘要: A method for combining transfer functions with predetermined key creation. In one embodiment, digital information, including a digital sample and format information, is protected by identifying and encoding a portion of the format information. Encoded digital information, including the digital sample and the encoded format information, is generated to protect the original digital information. In another embodiment, a digital signal, including digital samples in a file format having an inherent granularity, is protected by creating a predetermined key. The predetermined key is comprised of a transfer function-based mask set to manipulate data at the inherent granularity of the file format of the underlying digitized samples.
