Abstract: Composite applications can be created that utilize a plurality of different services across a plurality of different cloud stack layers. The composite applications are defined using the Service Component Architecture (SCA) model. Composite applications can be translated from the SCA model into a format compatible for a virtualization platform, such as the Open Virtualization Format (OVF). Composite applications, as defined in the format compatible for the virtualization platform, can be deployed on the virtualization platform.

Abstract: A natural language query tool comprising cascaded conditional random fields (CRFs) (e.g., a linear-chain CRF and a skip-chain CRF applied sequentially) processes natural language input to produce output that can be used in database searches. For example, cascaded CRFs extract entities from natural language input that correspond to column names or column values in a database, and identify relationships between the extracted entities. A search engine can execute queries based on output from the cascaded CRFs over an inverted index of a database, which can be based on one or more materialized views of the database. Results can be sorted (e.g., according to relevance scores) and presented in a user interface.

Abstract: A system and method for generating functional tests to verify code migrated from a first host to a second host. In one embodiment, source code is analyzed in order to generate functional tests that can be used for testing the re-hosted application. In particular, user-input scenarios are extracted from the source code and system output responses are determined based on the user-input scenarios. Functional tests can then be generated using the extracted user-input scenarios and output responses to ensure that the re-hosted application responds in a like manner.

Abstract: Code injection is detected based on code digests associated with hashes of selected portions of content supplied to clients by a server. A client receives the content and generates a corresponding code digest, and based upon a comparison with the code digest received from the server, determines if the received content has been corrupted. The code digest can be signed or supplied with a digital certification for verification that the code digest originated from the server providing the content.

Also, for example, source-code query results can be received, selections of facet values associated with groups of the source-code query results can be sent, and based on selected facet values, a subset of the source-code query results can be received.

Abstract: Various technologies related to one-time credit card numbers are presented. One-time credit card numbers can originate from a customer device and be independently generated by the customer device without online communication with an issuer. Signed transaction details can also be sent, providing non-repudiation of the purchase transaction. Merchant infrastructure need not be changed to accommodate the one-time credit card numbers. The technologies can be particularly resilient to replay, forgery, man-in-the-middle, and guessing attacks for credit card number generation or other usage by an attacker.
