The objective of this paper is to give a comprehensive introduction to applied cryptography with an engineer or computer scientist in mind. The emphasis is on the knowledge needed to create practical systems which supports integrity, confidentiality, or authenticity. Topics covered includes an introduction to the concepts in cryptography, attacks against cryptographic systems, key use and handling, random bit generation, encryption modes, and message authentication codes. Recommendations on algorithms and further reading is given in the end of the paper. This paper should make the reader able to build, understand and evaluate system descriptions and designs based on the cryptographic components described in the paper.

Cell phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others relate to coping with fixed focus limitations of cell phone cameras, e.g., in reading digital watermark data. Still others concern user interface improvements. A great number of other features and arrangements are also detailed.

This paper addresses the problem of retrieving images from large image databases. The method is based on local grayvalue invariants which are computed at automatically detected interest points. A voting algorithm and semilocal constraints make retrieval possible. Indexing allows for efficient retrieval from a database of more than 1,000 images. Experimental results show correct retrieval in the case of partial visibility, similarity transformations, extraneous features, and small perspective deformations.

Client-server systems and methods for transferring data via a network, including a wireless network, between a server (61) and one or more clients (41) or browsers that are spatially distributed (i.e., situated at different locations). At least one local client computer provides a user interface to interact with at least one remote server computer which implements data processing in response to the local client computer. The user interface may be a browser or a thin client.

An interactive television program guide system is provided. An interactive television program guide provides users with an opportunity to select programs for recording on a remote media server. Programs may also be recorded on a local media server. The program guide provides users with VCR-like control over programs that are played back from the media servers and over real-time cached copies of the programs. The program guide also provides users with an opportunity to designate gift recipients for whom programs may be recorded.

A data processing system provides a set of service value maps (SVMs) each having a plurality of nodes and linkages between nodes, forms a network model based on the SVMs and analyses the network model to compute aggregate values for the nodes to enable an identification of a node that matches at least one criterion. Analyzing can include using a degree centrality process where a value for each node is defined as a number of outgoing edges from the node, or an eigenvalue centrality process where a value of a node is proportional to a value of those nodes that the node is connected to. Each SVM can be represented as a directed acyclic graph (DAG) where each edge between nodes is an edge in the DAG. The at least one criterion can include a highest valued node identifying a value aggregation point (VAP) of the set of SVMs.

Packaged business applications such as SAP and Oracle offer significant benefits and are critical to transforming businesses using standard-based business processes and prepackaged software solutions. Business process configuration, solution development, and installation of packaged business applications for enterprises comprise a significant portion of the business and IT service industry today. This paper presents an approach to estimating project schedules, staffing, service costs, and business benefits of business transformation using packaged business applications. More specifically, it presents normative and constructive estimation models, software tools and methods for structuring project plans and strategies, configuring project schedules, estimating the cost and value of such projects, and supporting decisions for estimating cost and project schedules.

PROBLEM TO BE SOLVED: To provide a device and a method capable of recognizing and learning the size of an object such as a farm product. SOLUTION: An illumination source for irradiating a screen is provided, the illumination source is controlled and an image processing system obtains the first digital image of the screen provided with the object irradiated at a high level and the second digital image of the object irradiated at a low level. Algorithm is used and an object image is newly area-divided from the background image of the screen by the comparison of the two digital images. The processing image of a round object (usable so as to feature the size of the object) is compared with a stored reference image. When collation is performed, the size of the object is recognized. The processing image of the object of the unrecognized size is stored in a memory based on a specified standard by labelling the actual size of the object and the size of the object is recognized at the time of forming the image in the future. By this system, learning is made possible so as to recognize the size of the object not known beforehand.

A system and method allow a user to extract the set of customizations performed on an application and use these to estimate the time and effort and cost of (a) migrating to a new version of the application and/or (b) consolidating systems. The user can browse the extracted data and select configuration elements for re-use. After downloading the one or more configurations and comparing them, the user selects elements of the configurations for re-use. The first step is to scan one or more application systems and extract the configuration data using a surveyor. The method according to the invention automatically identifies configuration differences. The user then selects configuration elements for re-use. A graphic user interface (GUI) can be provided which allows the user to make these selections by dragging and dropping selected elements to a “To Be” configuration. The selected configurations are then uploaded and installed on an instance of the application.

The heterogeneousness and dynamics of web information sources are the major challenges to Internet-scale information integration. The information sources are different in contents and query interfaces. In addition, the sources can be highly dynamic in the sense that they can be added, removed, or updated with time. This paper introduces a novel information integration framework that leverages the industry standards on web services (WSDL/SOAP) and ontology description language (RDF/OWL), and a commercial database (IBM DB2 Information Integrator⎯DB2 II (DB2 II)). Taking advantage of the data integration and query optimization capability of DB2 II, this paper focuses on the methodologies to transform a user query to the queries on different sources and to combine the transformation results into a query to DB2 II. By wrapping information sources using web services and annotating them with regard to their contents, query capabilities and the logical relations between concepts, our query transformation engine is rooted in ontology-based reasoning. To the best of our knowledge, this is the first framework that uses web services as the interface of information sources and combines ontology-based reasoning, web services, semantic annotation on web services, as well as DB2 II to support Internet-scale information integration.
