Reverse Engineering Socialbot Infiltration Strategies in Twitter

Data extracted from social networks like Twitter are increasingly being used to build applications and services that mine and summarize public reactions to events, such as traffic monitoring platforms, identification of epidemic outbreaks, and public perception about people and brands. However, such services are vulnerable to attacks from socialbots $-$ automated accounts that mimic real users $-$ seeking to tamper statistics by posting messages generated automatically and interacting with legitimate users. Potentially, if created in large scale, socialbots could be used to bias or even invalidate many existing services, by infiltrating the social networks and acquiring trust of other users with time. This study aims at understanding infiltration strategies of socialbots in the Twitter microblogging platform. To this end, we create 120 socialbot accounts with different characteristics and strategies (e.g., gender specified in the profile, how active they are, the method used to generate their tweets, and the group of users they interact with), and investigate the extent to which these bots are able to infiltrate the Twitter social network. Our results show that even socialbots employing simple automated mechanisms are able to successfully infiltrate the network. Additionally, using a $2^k$ factorial design, we quantify infiltration effectiveness of different bot strategies. Our analysis unveils findings that are key for the design of detection and counter measurements approaches

Incluindo dados fisiológicos na ciência do comportamento: uma análise crítica Including physiological data in a science of behavior: a critical analysis

Resumo A posição dos analistas do comportamento sobre a inclusão de dados fisiológicos na análise do comportamento varia. David Schaal, um analista do comportamento contemporâneo, apontou vantagens de tal inclusão para a análise do comportamento em quatro pontos: (a) identificação de mecanismos de retenção do condicionamento operante; (b) a fisiologia dá explicações quando as descrições não são suficientes; (c) elucidação de mecanismos celular e neural de reforçamento e (d) caracterização de alterações degenerativas no cérebro. O presente artigo proporciona discussões futuras desses pontos se eles realmente representam uma vantagem `a análise do comportamento. É argumentado e exemplificado que a análise do comportamento e a neurociência não são multuamente exclusivas. Por fim, as condições sob as quais a inclusão de dados fisiológicos na análise do comportamento representa uma vantagem à área são delineadas. Palavras-chave: análise do comportamento, neurociência, dados fisiológicos, reducionismo Abstract The position of behavior analysts on the inclusion of physiological data in behavior analysis varies. David Schaal, a contemporary behavior analyst, addressed advantages of such inclusion to behavior analysis in four points: (a) identification of retention mechanisms of operant conditioning; (b) physiology provides explanations when descriptions are not sufficient; (c) elucidation of cellular and neural mechanisms of reinforcement; and (d) characterization of degenerative alterations in the brain. The present paper provides further discussion of these points as to whether they truly represent an advantage to behavior analysis. It is argued and exemplified that behavior analysis and neuroscience are not mutually exclusive. Finally, the conditions under which the inclusion of physiological data in behavior analysis represents an advantage to the field are delineated

Face Tracking: An approach for face identification, recognition and tracking for low-cost environments

Abstract. Applicable facial identification and recognition are great trends nowadays, representing a powerful tool needed in various application domains. Its use varies from authentication purposes, business intelligence, emotion recognition, and security services. For this last one, a very desirable application is the use of several cameras geographically sparse, where specific individuals can be recognized for crowded environments. This paper proposes the use of face recognition and identification to help in the development of a low-cost tool. A dataset with several face photos was built to simulate our experimental environment. The obtained preliminary results demonstrate the feasibility of the proposed approach for security applications
