Alessia De Rosa was born in Florence, Italy, in 1972. She received the Electronic Engineering degree and the Ph.D. degree in Informatics and Telecommunications from the University of Florence (Italy) in 1998 and 2002 respectively.

Since 2002, she has been working at the University of Florence as a post-doc researcher with the Department of Electronics and Telecommunications, now Department of Information Engineering, involved in the research activities of the IAPP - Image Analysis Processing and Protection Group, in the framework of National and International Research Projects. She also collaborates with the National Inter-University Consortium for Telecommunications (CNIT).

Since 2010 she contributes to the activity of FORLAB, Forensic Science Laboratory, at the PIN, base of the University of Florence in Prato.



Her main research interests are in the field of image processing and protection, including digital watermarking, human perception models for watermarking and quality assessment, image processing for industrial, medical and Cultural Heritage applications and image forensics for the integrity verification of visual content.
She has carried on these research activities in the framework of numerous projects.

She is co-author of publications on international journals and conferences as well as book chapters and she holds an Italian patent regarding digital watermarking. She is reviewer for several international journals and conferences in the field of image processing and security, including IEEE Transactions on Image Processing, IEEE Transactions on Signal Processing, IEEE Transactions on Information Forensics and Security, International Conference on Image Processing (ICIP), Information Hiding (IH). She was co-editor of the Proceedings “1st and 2nd COST#276 Workshop on Information and Knowledge Management for Integrated Media Communication”, November 27-29, 2001, Leganes, Madrid (SPAIN) - March, 25-26, 2002, Firenze (ITALY); member of the Organizing Committee of the “2004 International Workshop On Multimedia Signal Processing”, September 29 - October 1, 2004, Siena (ITALY); member of the Organizing Committee of the “2005 International Workshop On Digital Watermarking”, September 15-17, 2005, Siena (ITALY).



The research activity has been developed in the framework of National and International Projects funded by the European Commission. In particular:

  • Project EU IST REWIND, 2011-2014 (CNIT)
  • Project EU IST LivingKnowledge, 2009-2012 (CNIT)
  • Project EU IST SPEED (Signal Processing in the EncryptEd Domain), 2006- 2009 (UNIFI)
  • Project EU IST ECRYPT (European Network of Excellence in Cryptology), 2004- 2008 (CNIT)
  • Project PRIN2007 “Privacy aware processing of encrypted signals for treating sensitive information” funded by MIUR, 2008-2010 (UNIFI)
