摘要： Techniques are detailed for steganographically embedding auxiliary data (1030) within electronic content (e.g., audio, video, still imagery, etc.) (1020) in manners that are computationally simple, yet highly inconspicuous (1010). The embedded data can convey copyright or other ownership information, or may be used for device control purposes (e.g., preventing unauthorized reproduction). A number of countermeasures against removal of the auxiliary data are contemplated, including keying use of the content to the presence of such data. The embedded data may be made dependent on the media encoded, e.g., by modifying the embedded data in accordance with characteristics from the media. Encryption can also advantageously be employed (1040). Playback devices may be equipped to track IDs from previously-accessed content, and enforce usage rules. Some embodiments employ multiple watermarks to advantage, e.g., a robust watermark is encoded prior to distribution and indicates the content is protected, and a second watermark is encoded by the playback device and serves to uniquely link that content to that device. Some applications benefit from scrambling of content, in a manner that leaves certain information (e.g., from a header) unscrambled and freely accessible.

摘要： PROBLEM TO BE SOLVED: To provide a digital distribution and e-commerce system for preventing piracy of digital content. SOLUTION: Copyright notification and sales of metadata can help counteract the problem. The novel solution shows different methods to provide copyright notification and sell metadata, such as including identification of the content (via digital watermarks, fingerprints or header data) and a personal domain. Metadata is ideal to sell since it is dynamic, and, thus, is accessed from a master server. COPYRIGHT: (C)2011,JPO&INPIT

摘要： A method and system for provides routing of metadata related to media content, using content identifiers to locate the metadata content and rules to determine a subset of the metadata to deliver. This method registers globally unique identifiers for content objects. These globally unique identifiers each comprise a content identifier provided with the content object and a bounding identifier identifying a set of content identifiers of which the content identifier is a member. For each of the globally unique identifiers, information is maintained about a metadata source. The method receives a first content identifier for the content object, and uses a bounding identifier associated with the set of the first content identifier to determine the globally unique identifier for the first content identifier. The user is routed to the metadata source associated with globally unique identifier.

摘要： This disclosure describes methods and systems for synchronizing broadcast and network content, such as web content. It also describes related technology for facilitating linking from broadcast content to related information and e-commerce on a network. One method detailed in this disclosure synchronizes broadcast content with dynamic network content at a network address. This method embeds an identifier in a broadcast, extracts the identifier embedded in broadcast content, and uses the identifier to identify corresponding network content. The method then posts the corresponding network content on a network device located at the network address (e.g., a web page at the URL of the broadcaster). The network device (e.g., web server) is responsive to requests sent to the network address to provide the network content over a network. Using this method, the broadcast content is synchronized with the corresponding network content. This approach enables the content at the broadcaster's fixed web site URL to change dynamically with the broadcast. This approach is transparent to the user, who simply visits the same URL to get more information about current programming or purchase a product currently advertised in current programming.

摘要： A method for issuing a credential includes scanning in documents (e.g., breeder or ID documents) used to verify the applicant of the credential and creating data records including the image of the documents. As a means to reduce fraud, these data records are linked to the credential and to the issuer location, operator and time and place of issuance. If the document includes machine readable information, the method automatically reads the machine readable information from the document and uses at least part of the machine readable information from the document to pre-populate a form used to create a credential, such as an identification document. The method includes applying a transformation to the image of the document that enables protection against fraudulent use. The transformation secures the image of the document from tampering and/or enables tracking of the use of the document image to deter fraud. A method of verifying a credential comprises reading a physical security feature attribute on the credential, reading a logical attribute on the credential, and comparing information from the physical security feature with the logical storage element on the credential to verify the credential.
摘要翻译：用于发布凭证的方法包括扫描用于验证凭证申请人的文档（例如育种者或ID文档）并创建包括文档图像的数据记录。作为减少欺诈的一种手段，这些数据记录与证书和发行人地点，运营商以及发行时间和地点相关联。如果文档包括机器可读信息，则该方法自动从文档读取机器可读信息，并使用来自文档的机器可读信息的至少一部分预先填充用于创建凭证的表单，例如标识文档。该方法包括对文档的图像应用转换，使得能够防止欺诈性使用。该转换确保文档的图像免遭篡改和/或能够跟踪文档图像的使用，从而防止欺诈行为。验证凭证的方法包括读取凭证上的物理安全特征属性，读取凭证上的逻辑属性，以及将来自物理安全特征的信息与凭证上的逻辑存储元件进行比较以验证凭证。

摘要： The present invention provides a method of securing messages steganographically embedded in media (e.g., printed or electronic objects, audio, and video). In one implementation, a message inclues a first portion and a second portion. The first portion includes a first message and a first checksum, which are encrypted with a private key. The encrypted first protion is combined with the second portion. The second portion includes a second message and a second checksum. The combined encrypted first portion and the second portion form a signature. The signature is encrypted wth a common key or universal key, perhaps after error correction coding. The private key is uniquely associated with an entity such as a document issuing jurisdiction.

摘要： Consumers should be allowed to easily access content within their home, and share between their homes if allowed based upon geographical constraints, but not allow the content to be illegitimately shared between domains of different ownership. An efficient solution is to add intelligence information to the header of the IP packets that enables the firewall to determine if that packet, without requiring other packets from the same content and without touching the data within the packet, can be forwarded and/or if billing charges should apply.
