The remarkable success of AI-Generated Content (AIGC), especially diffusion image generation models, brings about unprecedented creative applications, but also creates fertile ground for malicious counterfeiting and crime. A highly effective family of forgery image detection methods based on diffusion reconstruction error has emerged, as images generated by diffusion are more easily reconstructed by any diffusion model. However, we find that existing methods only use reconstruction error from a single time step, failing to fully leverage the entire reconstruction process. To this end, we propose to comprehensively consider every single time step to form the Temporal Reconstruction Error (TRE) that offers a richer feature representation. Furthermore, we design temporal aggregation and spatial focusing modules from two dimensions respectively to more effectively extract discriminative information from the TRE feature. Finally, we validate the proposed method on two popular datasets, and experimental results demonstrate that the proposed approach achieves state-of-the-art performance.

Robust digital watermarking systems are important building blocks in applications such as fingerprinting, dispute resolving or direct proofs of authorship, where the presence of a watermark serves as evidence for some fact, e.g., illegal redistribution or authorship. A major drawback of (symmetric) watermarking schemes in this context is that proving the presence of a watermark requires disclosing security critical detection information (watermark, detection key, original data) to a (potentially malicious) verifying party. This may completely jeopardise the security of embedded watermarks once this information is revealed. To overcome this problem recent work on secure watermark detection proposes cryptographic proofs that perform the detection on concealed detection information. The proposed solutions focus on correlation-based detection and can be applied to any watermarking scheme whose detection criteria can be expressed as a polynomial relation between the quantities required for the detection. In this paper, we present in-depth guidelines for the adoptions required to transform well-established watermarking schemes by Cox et al and Piva et al into secure cryptographic proofs in the non-interactive setting. Moreover, we present our implementation, its performance results and the corresponding tool we have developed for this purpose. Our results underpin the practicability of the cryptographic approach. © springer-Verlag Berlin Heidelberg 2006.

Processing massive data flow in intrusion detection systems (IDS) become a serious challenge. It is considered as a major deficiency while handling heterogeneous and nonstationary data stream to uncover anomaly in the online operational mode. This paper proposes a novel online method that constructs connections from the massive data flow for evaluating IDS models. The proposed method overcomes this challenge by using a queuing concept of dynamic window size. It captures network traffic and hosts events constantly and handles them synchronously within time slot windows inside the queue in order to construct connection vectors based on certain features. We have evaluated the method in offline mode using DARPA dump data flow and in online mode using a simulated network at the university campus. In addition, we have evaluated our IDS model using the constructed connections to proof the feasibility and plausibility of the proposed method in IDS area. The performance evaluation confirms that, the proposed method is able to operate in offline as well online modes efficiently. Moreover, constructed connections are very adequate for training and evaluating IDS models.

Artificial neural network, recently, is considered as a vibrant area in machine learning. Particularly, Growing Hierarchical Self Organizing Map (GHSOM) model, as an intelligent neural network, is vital in intrusion detection system (IDS). However, it suffers from prosaic topology, adheres to random weight vectors initialization, which degrades the performance metrics. In this paper, we progressively enhance the GHSOM to present a new delicate version, named EGHSOM. It consists of a meaningful initialization process instead of random initialization, a novel splitting threshold technique to stabilize the growth topology, merging and pruning methods on neurons to settle the topology and accelerate the detection, and a classification-confidence threshold to detect unknown anomaly in computer networks. The final model is trained using real-time traffic in addition to NSL-KDD and compared with other approaches. The result shows that EGHSOM is more efficacious than others and solves major drawbacks of intrusion detection in networks.

During the widening of information technology, the need to a framework that efficiently constructs connection vectors from online data flow for evaluating intrusion detection models has become fundamental. Moreover, known datasets in intrusion detection are either outdated or offline aggregated. Therefore, these datasets are not adequate for performance evaluation anymore. In this paper we present a novel framework, OptiFilter, that mines network packets and host events, based on significant features in intrusion detection. The framework collects network packets and host events continuously in real-time and parses them to a queue of dynamic windows, then it generates connection vectors accordingly. We evaluate the framework in a real-time heterogeneous network and compare it with other benchmark datasets. Our framework shows promising results with minimal processing time for maximum amount of packets. Moreover, it can constantly produce significant and meaningful datasets for evaluating intrusion detection systems.

Voice-over-IP systems are quite frequently attacked with the intent of service theft. While VoIP security has been intensively researched in the past, devised solutions often demand significant changes to the VoIP systems. In addition, several solutions propose the filtering of telephone calls, but these solutions only have a limited focus on the privacy rights of the call participants. We propose a method for analyzing communication records with the primary purpose to prevent VoIP attacks. Moreover, our approach integrates with little effort into common VoIP usage scenarios. As an example we use the prevention of toll-fraud attacks as a running example. The analysis of the communication records, however, requires investigating personal information in the communication records, e.g., call habits and phone numbers. Consequently we give an overview of major US and EU laws and regulations to elicit privacy requirements. We also demonstrate how these requirements can be implemented using Comercial-Off-The-Shelf VoIP systems. © 2012 IEEE.

Many companies have already adopted their business processes to be in accordance with defined and organized standards. Two standards that are sought after by companies are IT Infrastructure Library (ITIL) and ISO 27001. Often companies start certifying their business processes with ITIL and continue with ISO 27001. For small and medium-sized businesses, it is difficult to prepare and maintain the ISO 27001 certification. The IT departments of these companies often do not have the time to fully observere standards as part of their daily routine. ITIL and ISO 27001 perfectly fit into companies and help reduce errors through the standardization and comparability of products and services between themselves and other companies and partners. ISO 27001 specifically looks at security risks, countermeasures and remedial actions. We start with the processes that need to be in place for implementing ITIL in an organisation's business processes. We use a cloud service provider as a running example and compare ITIL processes with ISO 27001 processes. We identify which aspects of these two standards can be better executed. We propose a mapping between ITIL and ISO 27001 that makes them easier to understand and assists with the certification process. We show further how to prepare for audits as well as re-certification. Often, these two processes are seen separately and not in conjunction, where synergies can be exploited. Legal requirements, compliance and data security play an integral part in this process. In essence, we present checklists and guidelines for companies who want to prepare for standardization or that are already certified, but want to improve their business processes. We illustrate our method using an high availability video conferencing cloud example. © 2013 IFIP International Federation for Information Processing.
