With the increasing use of Internet technologies, the impressive evolution of digital media and the emergence of electronic commerce, a need for securing virtual worlds remains a significant challenge because of incessant criminal acts (e.g. verbal harassment, fraud and money laundry, theft or data piracy, etc). In order to fill the gaps in information security, we propose, in this paper, an approach for facial recognition applied in the virtual world on non-biological entities (avatars) based on the exploration of wavelet transforms for the characterization and on Support Vector Machines for the classification. Various experiments were carried out on a dataset of 1800 images collected from popular virtual worlds representing various facial expressions of avatars. Recorded tests have shown promising and encouraging results for such first contribution within the framework of this new research direction.
