Author Obfuscation: Attacking the State of the Art in Authorship Verification
نویسندگان
چکیده
We report on the first large-scale evaluation of author obfuscation approaches built to attack authorship verification approaches: the impact of 3 obfuscators on the performance of a total of 44 authorship verification approaches has been measured and analyzed. The best-performing obfuscator successfully impacts the decision-making process of the authorship verifiers on average in about 47% of the cases, causing them to misjudge a given pair of documents as having been written by “different authors” when in fact they would have decided otherwise if one of them had not been automatically obfuscated. The evaluated obfuscators have been submitted to a shared task on author obfuscation that we organized at the PAN 2016 lab on digital text forensics. We contribute further by surveying the literature on author obfuscation, by collecting and organizing evaluation methodology for this domain, and by introducing performance measures tailored to measuring the impact of author obfuscation on authorship verification.

Overview of the Author Obfuscation Task at PAN 2017: Safety Evaluation Revisited
We report on the second large-scale evaluation of style obfuscation approaches in a shared task on author obfuscation, organized at the PAN 2017 lab on digital text forensics. Author obfuscation means to automatically paraphrase a given text such that state-of-the-art authorship verification approaches misjudge a given pair of documents as having been written by “different authors” if in fact t...
متن کامل“Appropriation Art” and Recognition of the Legal Status of the Author
It is often thought that appropriation art doesn’t give rise to its traditional concept and place. Because there are secondary works in the world of visual arts that are taken from the original works. From a legal point of view despite their uniqueness, definite and certain material existence of these works, the situation of the author is not very clear. “How can be explained the authorship re...
متن کاملAnalyzing Stylometric Approaches to Author Obfuscation
Authorship attribution is an important and emerging security tool. However, just as criminals may wear gloves to hide their fingerprints, so too may criminal authors mask their writing styles to escape detection. Most authorship studies have focused on cooperative and/or unaware authors who do not take such precautions. This paper analyzes the methods implemented in the Java Graphical Authorshi...
متن کاملDistractorless Authorship Verification
Authorship verification is the task of, given a document and a candidate author, determining whether or not the document was written by the candidate author. Traditional approaches to authorship verification have revolved around a “candidate author vs. everything else” approach. Thus, perhaps the most important aspect of performing authorship verification on a document is the development of an ...
متن کاملOverview of PAN'16 - New Challenges for Authorship Analysis: Cross-Genre Profiling, Clustering, Diarization, and Obfuscation
This paper presents an overview of the PAN/CLEF evaluation lab. During the last decade, PAN has been established as the main forum of digital text forensic research. PAN 2016 comprises three shared tasks: (i) author identification, addressing author clustering and diarization (or intrinsic plagiarism detection); (ii) author profiling, addressing age and gender prediction from a crossgenre persp...
