Datamart Management System
ABSTRACT
Current
event processing systems lack methods to preserve privacy constraints of
incoming event streams in a chain of subsequently applied stream operations.
This is a problem in large-scale distributed applications like a logistic chain
where event processing operators may be spread over multiple security domains.
An adversary can infer from legally received outgoing event streams
confidential input streams of the event processing system. This paper presents
a fine-grained access management for complex event processing. Each incoming
event stream can be protected by the specification of an access policy and is
enforced by algorithms for access consolidation. The utility of the event processing
system is increased by providing and computing in a scalable manner a measure
for the obfuscation of event streams. An obfuscation threshold as part of the
access policy allows to ignore access requirements and deliver events which
have achieved a sufficient high obfuscation level.
Existing System
On the one hand, sampling
techniques can be used to estimate the conditional probabilities of the
Bayesian network. However, their precision depends strongly on the number of
samples taken from the network, and no approximation scheme exists that allows
to draw samples in polynomial time to achieve a certain precision. This makes
the approximate algorithms infeasible for security applications, since no guarantees
can be made in appropriate time. On the other hand the complexity of calculating
exact inference can be reduced by storing partial results of the
inference calculation which otherwise would have to be calculated multiple
times. However, the benefit of these optimizations is heavily dependent on the
structure of the Bayesian network.
Proposed System
A role-based access control is
proposed. Pesonen et al. and Bacon et al. discuss how publish/subscribe systems
can be secured by introducing access control policies in a multi-domain
architecture. They describe how event communication between the domains can be supported.
Opyrchal et al. present the concept of event owners that can be specified.
These are used to provide access to their events. Tariq et al. propose a
solution to provide authentication and confidentiality in broker-less content-based
publish/subscribe systems. Our work is based on the previous work which make
event communication secure among different entities in the system a. We assume
the presence of a system that can handle access control on events. Based on
this, we use policy composition in order to derive the necessary access
policies at any point during the event processing steps.
IMPLEMENTATION
Implementation is the stage of the project when the theoretical
design is turned out into a working system. Thus it can be considered to be the
most critical stage in achieving a successful new system and in giving the
user, confidence that the new system will work and be effective.
The implementation stage involves careful planning,
investigation of the existing system and it’s constraints on implementation,
designing of methods to achieve changeover and evaluation of changeover
methods.

DESCRIPTION:
1.
Event Processing
2.
Manufacturer

Shipping Company
4.
Customer
Event
processing
Event
processing systems respond to events in the system’s environment or user interface.
The key characteristic of event processing systems is that the timing of events
is unpredictable and the system must be able to cope with these events when
they occur.
