Data Mining Practical Machine Learning Tools and Techniques

Aspect] is a simple and practical aspect-oriented extension to Java With just a few new constructs, AspectJ provides support for modular implementation of a range of crosscutting concerns. In AspectJ's dynamic join point model, join points are well-defined points in the execution of the program; pointcuts are collections of join points; advice are special method-like constructs that can be attached to pointcuts; and aspects are modular units of crosscutting implementation, comprising pointcuts, advice, and ordinary Java member declarations. AspectJ code is compiled into standard Java bytecode. Simple extensions to existing Java development environments make it possible to browse the crosscutting structure of aspects in the same kind of way as one browses the inheritance structure of classes. Several examples show that AspectJ is powerful, and that programs written using it are easy to understand.

Digital watermarking is a key ingredient to copyright protection. It provides a solution to illegal copying of digital material and has many other useful applications such as broadcast monitoring and the recording of electronic transactions. Now, for the first time, there is a book that focuses exclusively on this exciting technology. Digital Watermarking covers the crucial research findings in the field: it explains the principles underlying digital watermarking technologies, describes the requirements that have given rise to them, and discusses the diverse ends to which these technologies are being applied. As a result, additional groundwork is laid for future developments in this field, helping the reader understand and anticipate new approaches and applications.

The fast growing Internet technology has affected many areas of human life. As it offers a convenient and widely accepted approach for communication and service distribution it is expected to continue its influence to future system design. Motivated from this successful spreading we assume hypothetical scenarios in our paper, whereby automotive components might also be influenced by omnipresent communication in near future. If such a development would take place it becomes important to investigate the influence to security and safety aspects. Based on today's wide variety of Internet based security attacks our goal is therefore to simulate and analyze potential security risks and their impact to safety constraints when cars would become equipped and connected with an IP based protocol via unique IP addresses. Therefore, our work should motivate the inserting of security mechanisms into the design, implementation and configuration of the car IT systems from the beginning of the development, which we substantiate by practical demo attacks on recent automotive technology.

Non-destructive latent fingerprint acquisition is an emerging field of research, which, unlike traditional methods,
makes latent fingerprints available for additional verification or further analysis like tests for substance abuse or
age estimation. In this paper a series of tests is performed to investigate the overall suitability of a high resolution
off-the-shelf chromatic white light sensor for the contact-less and non-destructive latent fingerprint acquisition.
Our paper focuses on scanning previously determined regions with exemplary acquisition parameter settings.
3D height field and reflection data of five different latent fingerprints on six different types of surfaces (HDD
platter, brushed metal, painted car body (metallic and non-metallic finish), blued metal, veneered plywood) are
experimentally studied. Pre-processing is performed by removing low-frequency gradients. The quality of the
results is assessed subjectively; no automated feature extraction is performed. Additionally, the degradation
of the fingerprint during the acquisition period is observed. While the quality of the acquired data is highly
dependent on surface structure, the sensor is capable of detecting the fingerprint on all sample surfaces. On blued
metal the residual material is detected; however, the ridge line structure dissolves within minutes after fingerprint
placement.

Non-destructive forensic latent fingerprint acquisition with chromatic white light sensors

This paper provides first ideas and considerations for designing and developing future technologies relevant for challenging privacy-preserving preventive applications of contact-less sensors. We introduce four use-cases: preventive detailed acquisition of fingerprints, coarse scans for fingerprint localisation, separation of overlapping fingerprints and age determination for manipulation detection and automatic securing of evidence. To enable and support these four use-cases in future, we suggest developing four techniques: coarse scans, detailed scans, separation and age determination of fingerprints. We derive a new definition for the separation from a forensic approach: presence detection of overlapping fingerprints, estimation of the number of fingerprints, separation and sequence (order) detection. We discuss main challenges for technical solutions enabling the suggested privacy-preserving use-cases combined with a brief summary of preliminary results from our first experiments. We analyse the legal principles and requirements for European law and the design of the use-cases, which show tendencies for other countries.

A wide range of watermarking evaluation approaches and especially image benchmarking suites have been described in the literature. Our paper sets the main focus on the evaluation of digital audio watermarking with StirMark Benchmark for Audio (SMBA). Here we describe the currently implemented single geometric attacks in detail and introduce our so-called attack profiles. Profiles reflect an application oriented point of view ranging from the normal usage of audio content like internet radio or music shops up to typical attacker scenarios. In particular we present a definition of an extended profile which is composed of three basic profiles specific for annotation watermarks. Furthermore, we demonstrate how SMBA attacks can be used to evaluate the transparency of digital watermarking algorithms regarding the embedding strength. Test results based on an example audio watermarking algorithm and the measurement of transparency and capacity are presented.

Audio watermark attacks: from single to profile attacks

Digital watermarking has become an accepted technology for enabling multimedia protection schemes. Based on the introduced media independent protocol schemes for invertible data authentication in references 2, 4 and 5 we discuss the design of a new 3D invertible labeling technique to ensure and require high data integrity. We combine digital signature schemes and digital watermarking to provide a public verifiable integrity. Furthermore the protocol steps in the other papers to ensure that the original data can only be reproduced with a secret key is adopted for 3D meshes. The goal is to show how the existing protocol can be used for 3D meshes to provide solutions for authentication watermarking. In our design concept and evaluation we see that due to the nature of 3D meshes the invertible function are different from the image and audio concepts to achieve invertibility to guaranty reversibility of the original. Therefore we introduce a concept for distortion free invertibility and a concept for adjustable minimum distortion invertibility.
