Web Services in Building Automation: Mapping KNX to oBIX

Abstract: Web services are a key technology for enabling interoperable machine-to-machine interaction over a network. They also lend themselves excellently to the integration of automation and IT systems. This paper discusses oBIX, a new standard for representing and accessing building automation (BA) data via Web services. It is shown how access to a BA system that follows the KNX protocol standard can be faithfully represented by way of oBIX entities. A prototype implementation of such a gateway is presented. The extensible nature of the oBIX data model is leveraged by using it to express the required KNX-oBIX mapping information as well. This approach allows a particularly clear and efficient gateway design.

Hypervisor assisted single instance data access by multiple virtual machines

Abstract: A data instance to be shared by multiple virtual machines is stored at a hypervisor level. A file system driver is provided to each virtual machine. Each virtual machine mounts a file system backed by the data instance, and thus has read access to the data through its mounted file system. A virtual machine is suspended. A copy of the data instance is saved as part of the stored image of the suspended virtual machine. The suspended virtual machine is subsequently restored from the stored image, and the copy of the data instance is present in the restored virtual machine. The copy of the data instance is detected at a hypervisor level, and the restored virtual machine is provided with read access to the data instance through its mounted filed system.

Multi-tenant agile database connector

Abstract: A module provides an interface between a multi-tenant database and a non-tenant-specific application instance such that the application instance sends data access commands to the module as if it is communicating with a single-tenant database. The module translates the non-tenant-specific data access command from the non-tenant-aware application into a multi-tenant data access command, as needed, without needing to alter the non-tenant specific application instance in any way. In this manner, a single-tenant application could be used by multiple tenants in a multi-tenant environment.

Secure access to data over the Internet

Abstract: Security issues are the major roadblock currently preventing greater access to databases over the Internet. In this paper, we propose a framework for secure access to databases by a wide audience over the Internet, using World Wide Web information servers, a modified version of the NCSA Mosaic Internet browser and role wrappers (software modules that assign roles to incoming database requests, based on the credentials submitted with the request). We also describe an application embodying this framework. >

Data processing systems for generating and populating a data inventory for processing data access requests

Abstract: In particular embodiments, a data processing data inventory generation system is configured to: (1) generate a data model (e.g., a data inventory) for one or more data assets utilized by a particular organization; (2) generate a respective data inventory for each of the one or more data assets; and (3) map one or more relationships between one or more aspects of the data inventory, the one or more data assets, etc. within the data model. In particular embodiments, a data asset (e.g., data system, software application, etc.) may include any entity that collects, processes, contains, and/or transfers personal data (e.g., a software application, database, website, server, etc.). A data asset may include any software or device (e.g., server or servers) utilized by a particular entity for such data collection, processing, transfer, storage, etc. The system may then utilize the generated model to fulfil a data subject access request.
