offered free of charge. Access control is the underlying mechanism for all use cases that require conditional data access like licensing and billing. The SANY system shall
provide several security related services that facilitate the enforcement of access control policies:
-
Authentication verification of user identities, support for multiple authentication mechanisms
-
Authorisation support of roles, authorisation for services, authorisation on the data level, etc
-
User Management storage and management of user profiles
-
Data Integrity. Another security topic is protection of measurement data against manipulation. In order to ensure data integrity cryptographic measures like digital
signatures may be necessary at different operational levels e.g. during transmission, storage in databases etc..
-
Flexible security architecture. The overall security architecture shall be able to integrate security measures without changes to the architecture as security
requirements depend heavily on concrete use case requirements. For example, it may be a security problem to allow certain users of the SANY system to track sensor data
over a period of time e.g. a shipping company does not want competitors to know the exact routes of their ships.
4.6.6 Processing and Fusion
-
Interfaces for data processing services development. The SANY system shall provide general data processing services such as merging data and extracting relevant
data for reports. In addition, the SANY system shall be capable of handling meta- information. This includes the storage of intermediate information to assure that
overall services and service chains can execute with acceptable speed.
-
Image analysis and feature extraction. The SANY system shall be capable of processing images and extracting features e.g. such as a road or a watercourse.
-
Homogenisation of spatial and temporal measurement resolution The SANY system shall be capable of handling and adjusting different temporal andor spatial
resolutions of sensor data, e.g. through data interpolation and aggregation. Furthermore, the SANY system shall cope with missing values in data series.
-
Fusion of measurements of same phenomenon. The SANY system shall be capable of processing and merging measurements of the same phenomenon using different
sensor equipment. The information about the source shall be stored in meta- information. The different data, possibly generated by the equipment at different
times, shall be processed using a fusion service.
-
Library of algorithms as statistical processing services. The SANY architecture shall provide a mechanism for defining re-usable processing services, e.g. for data
interpolation and data fusion.

-
Workflow. The SANY system shall be capable of processing service chaining by workflows. The output results of a model service may be connected to the input of
another subsequent process.
-
Visualisation. In many use cases several services of visualisation are described, e.g. maps or diagrams. The SANY system shall offer flexible means to visualise data in
different styles.
