Systems and Methods for Secure Transaction Management and Electronic Rights Protection

A method and device are provided for controlling access to data. Portions of the data are protected and rules concerning access rights to the data are determined. Access to the protected portions of the data is prevented, other than in a non-useable form; and users are provided access to the data only in accordance with the rules as enforced by a mechanism protected by tamper detection. A method is also provided for distributing data for subsequent controlled use of those data. The method includes protecting portions of the data; preventing access to the protected portions of the data other than in a non-useable form; determining rules concerning access rights to the data; protecting the rules; and providing a package including: the protected portions of the data and the protected rules. A user is provided controlled access to the distributed data only in accordance with the rules as enforced by a mechanism protected by tamper protection. A device is provided for controlling access to data having protected data portions and rules concerning access rights to the data. The device includes means for storing the rules; and means for accessing the protected data portions only in accordance with the rules, whereby user access to the protected data portions is permitted only if the rules indicate that the user is allowed to access the portions of the data.

Rights management information is used at least in part in a matching, narrowcasting, classifying and/or selecting process. A matching and classification utility system comprising a kind of Commerce Utility System is used to perform the matching, narrowcasting, classifying and/or selecting. The matching and classification utility system may match, narrowcast, classify and/or select people and/or things, non-limiting examples of which include software objects. The Matching and Classification Utility system may use any pre-existing classification schemes, including at least some rights management information and/or other qualitative and/or parameter data indicating and/or defining classes, classification systems, class hierarchies, category schemes, class assignments, category assignments, and/or class membership. The Matching and Classification Utility may also use at least some rights management information together with any artificial intelligence, expert system, statistical, computational, manual, or any other means to define new classes, class hierarchies, classification systems, category schemes, and/or assign persons, things, and/or groups of persons and/or things to at least one class.

Documents and other items can be delivered electronically from sender to recipient with a level of trustedness approaching or exceeding that provided by a personal document courier. A trusted electronic go-between can validate, witness and/or archive transactions while, in some cases, actively participating in or directing the transaction. Printed or imaged documents can be marked using handwritten signature images, seal images, electronic fingerprinting, watermarking, and/or steganography. Electronic commercial transactions and transmissions take place in a reliable, “trusted” virtual distribution environment that provides significant efficiency and cost savings benefits to users in addition to providing an extremely high degree of confidence and trustedness. The systems and techniques have many uses including but not limited to secure document delivery, execution of legal documents, and electronic data interchange (EDI).

Trusted and secure techniques, systems and methods for item delivery and execution

A descriptive data structure provides an abstract representation of a rights management data structure such as a secure container. The abstract representation may describe, for example, the layout of the rights management data structure. It can also provide metadata describing or defining other characteristics of rights management data structure use and/or processing. For example, the descriptive data structure can provide integrity constraints that provide a way to state rules about associated information. The abstract representation can be used to create rights management data structures that are interoperable and compatible with one another. This arrangement preserves flexibility and ease of use without compromising security.

Techniques for defining, using and manipulating rights management data structures

A method of distributing a plurality of data files to a plurality of recipients including the steps of: placing encrypted copies of the data files to be distributed on a plurality of identical media and providing the recipients with media reading devices having data file decryption capability; logically arranging the data files into data file groups; in response to a recipient's request for access to selected file groups providing the recipient with a group access map indicative of the file groups to which access is requested; in further response to a recipient's request for access to selected file groups providing the recipient with a password to be used for access verification; completing an access verification operation using the group access map and the password and data indicative of the media being read and data indicative of the reading device being used; providing access to the data files in the file groups to which access is requested by use of the group access map; and decrypting the accessed data files.

A Z-fold print media handling system for printing banners and the like uses an inkjet printing mechanism without a tractor-feed. A series of stuttering stopping and starting steps generates varying static and dynamic frictional forces to separate the first sheet of a Z-fold stack from the remainder of the stack. Both conventional cut-sheet media and Z-fold media are fed using the same printing mechanism, which pulls the media toward a printzone through frictional engagement with a first surface of the media. To prevent printhead crashes and smearing the image near the perforations joining the Z-fold sheets, the printhead to media spacing is increased for Z-fold media over the standard spacing used for cut-sheet media. A cam feature is incorporated into the media drive clutch disk to determine whether an operator has set a selector lever for cut-sheet or Z-fold printhead to media spacing.

Optimization of printer throughput is achieved through the use of a printhead carriage control method and a corresponding apparatus which directs acceleration of the printhead carriage based on the length of a future printhead carriage swath. According to the improved method, print data is periodically previewed to determine the length of a future swath, and the carriage is accelerated to an optimal printing velocity which is selected based on the determined swath length. The printer prints at the selected printing velocity, and then decelerates the carriage to complete the pass. During deceleration, the medium is advanced to its next position, and the print data is again previewed in order to determine the swath length for use in selecting the optimal printing velocity for the next carriage pass.

Various embodiments of a method for changing the perceived view direction in an image of a person's face are disclosed.

System and method for adjusting perceived eye rotation in image of face

A printer control method and apparatus are provided whereby print media feed and printhead carriage acceleration are overlapped in order to optimize the time which a printer spends preparing to print. The printhead carriage is accelerated at a time which has been determined to provide for concurrent completion of printhead carriage acceleration and media feed. This typically is accomplished by periodically previewing print data stored in memory for use in identifying a duration of time required to accelerate the printhead carriage to printing velocity and a duration of time required to advance the print medium. The difference between these times determines when to begin printhead carriage acceleration.
