Jones","doi":"10.1109/ISDFS.2019.8757506","DOIUrl":"https://doi.org/10.1109/ISDFS.2019.8757506","url":null,"abstract":"Previous efforts to detect cross-instance cloud remanence have consisted of searching current instance unallocated space for fragments easily attributable to a prior user or instance, and results were necessarily dependent on the specific instances tested and the search terms employed by the investigator. In contrast, this work developed, tested, and applied a general method to detect potential cross-instance cloud remanence that does not depend on specific instances or search terms. This method collects unallocated space from multiple cloud virtual machine instances based on the same cloud provider template. Empty sectors and sectors which also appear in the allocated space of that instance are removed from the candidate remanence list, and the remaining sectors are compared to sectors from instances based on other templates from that same provider; a matching sector indicate potential cross-instance remanence. Matching sectors are further evaluated by considering contiguous sectors and mapping back to the source file from the other instance template, providing additional evidence that the recovered fragments may in fact be content from another instance. This work first found that unallocated space from multiple cloud instances based on the same template is not empty, random, nor identical - in itself an indicator of possible cross-instance remanence. This work also found sectors in unallocated space of multiple instances that matched contiguous portions of files from instances created from other templates, providing a focused area for determining whether cross-instance data remanence exists. This work contributes a general method to indicate potential cross-instance cloud data remanence which is not dependent on a specific provider or infrastructure, instance details, or the presence of specific user-attributable remnant fragments. A tool to implement the method was developed, validated, and then run on Amazon's AWS cloud service.","PeriodicalId":247412,"journal":{"name":"2019 7th International Symposium on Digital Forensics and Security (ISDFS)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129773995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This information helps forensic investigators to guess initial suspects and do further investigations on the suspicious computers. Network and system administrators also use the information to identify security weaknesses of their systems and networks. The goal of this paper is to identify the origins and to reconstruct the propagation path of preferential scanning worm back-in-time. The main idea of this paper is to use back-to-origin modeling and a step-by-step improvement, to identify the origins and to reconstruct the propagation path after the worm outbreak using information gathered over the network. We construct a probabilistic model to receive features over the network and estimate infection status of nodes. We also developed an algorithm that identifies the origins and reconstructs the propagation path, back-in-time using the learned model. In order to achieve this, we used a 4-step method. The proposed method has acceptable accuracy.","PeriodicalId":247412,"journal":{"name":"2019 7th International Symposium on Digital Forensics and Security (ISDFS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125577309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to various digital image processing methods they became part areas such as astronomy, agriculture and more. One of the main task in image processing application is segmentation. Since segmentation represents rather important problem, various methods were proposed in the past. One of the methods is to use clustering algorithms which is explored in this paper. We propose k-means algorithm for digital image segmentation. K-means algorithm's well known drawback is the high possibility of getting trapped into local optima. In this paper we proposed brain storm optimization algorithm for optimizing k-means algorithm used for digital image segmentation. Our proposed algorithm is tested on several benchmark images and the results are compared with other stat-of-the-art algorithms.

Both JPEG and fractal compression algorithms can be used in the data compression process of the proposed new algorithm. In the encryption process, a chaotic key planning algorithm has been used. Chaotic systems are used as an entropy source. This approach, based on the one time pad principle, is unconditionally secure because it uses different secret keys in each encryption process.

The development of digital watermarking methods that are robust against allowable transformations, whose most typical example is lossy compression, presents a challenging task. Such methods and watermarks embedded by them are called semi-fragile. The paper considers different semi-fragile watermarking techniques that resisting JPEG. We focus on the analysis of the effect of watermark capacity, positions of spectral coefficients selected for embedding, and specific algorithms of coefficients modification on the quality of the resulting (secure) image and the authentication accuracy.

Furthermore, it builds on standards and specifications to accomplish a highly resilient and scalable solution. The approach is tested on several hardware platforms.
