  • Patent number: 8144368
    Abstract: This disclosure describes methods for using embedded auxiliary signals in documents for copy detection and other applications. In on application, the auxiliary signal is formed as an array of elements selected from a set of print structures with properties that change differently in response to copy operations. These changes in properties of the print structures that carry the embedded auxiliary signal are automatically detectable. For example, the changes make the embedded auxiliary signal more or less detectable. The extent to which the auxiliary data is detected forms a detection metric used in combination with one or more other metrics to differentiate copies from originals. Examples of sets of properties of the print structures that change differently in response to copy operations include sets of colors (including different types of inks), sets of screens or dot structures that have varying dot gain, sets of structures with different aliasing effects, etc.

In the case where the content is to be disclosed to a plurality of users having different roles, the encryption of secret keys is performed separately for each user. These encrypted contents and encrypted secret keys are used to generate encrypted text.

  • Patent number: 7797524
    Abstract: In a dynamic database association method, a static contact list is dynamically associated with a dynamic instant messenger contact list so that a user of a first database may access a contact list of a second database with associative links between said first and second databases. The user is also prevented from searching both the first and second databases simultaneously. Moreover, in the abovementioned dynamic database association method, a unified user interface is utilized for integrating management of at least two databases, where each of the at least two databases is operated under a different communication network. Therefore, the defect of inconveniencing the user by utilizing different user interfaces for different databases is avoided.

  • Patent number: 7788179
    Abstract: A cellular phone company closes a contract with a user to the effect that the cellular phone company collects a predetermined basic charge from the user together with a communication charge. When the user intends to print out a contents, the user sends authentication information given to him/her to a contents server from his/her cellular phone. The contents server authenticates the user based on the authentication information, and sends contents data for browsing to the user's cellular phone, if authentication is successful. The user's cellular phone sends print request information to a printer. The printer acquires corresponding contents data for print-out from the contents server in accordance with the print request information, and prints out the contents. The cellular phone company collects the basic charge and the communication charge from the user based on the contract.

  • Patent number: 7770030
    Abstract: A system and method for enabling broadcast programs to be copied once only by consumer recorders includes writing a unique media identification on each blank disk to which content is to copied in a read-only area of the disk before it is initially recorded. Also, a one-way key management media key block is written to the disk. A content key is derived by combining a media key, derived from the media key block, with the media identification. Additionally, to facilitate copying the content one time only, an exchange key is established between the recorder and a sender such as a satellite receiver or a disk player that is associated with the recorder, and the exchange key is modified with one or more special numbers representing control commands including copy once and copy no more. The modified exchange key is then encrypted using the content key to render an encrypted modified exchange key, and the encrypted modified exchange key is then hashed with a nonce to render a bus content key.

  • Patent number: 7761704
    Abstract: One embodiment of the present invention provides a system that can expire encrypted-data. During operation, the system receives an expiry-request that includes object-identifying information, which can be used to identify a set of database objects that contain the encrypted-data, wherein a database object can be a table, a partition, a row, or a column in a row. Furthermore, a database object can have an expiration time, and it can be stored in an archive, which is typically used to store large amounts of data for long periods using a slower, but cheaper storage medium than the storage medium used by the database. The system then identifies a set of keys for the encrypted-data using the object-identifying information. Next, the system deletes the set of keys, thereby expiring the encrypted-data. Note that, deleting the set of keys ensures that the secure key repository does not contain any stale keys associated with expired encrypted-data.

  • Patent number: RE41546
    Abstract: Techniques for reorganizing security levels without implicating accessibility to secured files classified in accordance to one of the security levels are disclosed. In a case of adding a new security level, the controllability or restrictiveness of the new security level is determined with respect to the most restrictive security level or the least security level in a set of existing security levels. A set of proper security parameters are then generated for the new security level and subsequently the existing security levels are reorganized to accommodate the new security level. In a case of removing a security level from the existing security levels, the security parameters for the security level to be deleted are either folded up or down to an immediate next security level, depending on implementation.
