The aim of this paper is analyze these changes and propose a methodology of the detection PRNU of compact cameras with zoom. cav_un_auth*0276641 Doktorandské Dny 2011 Praha 11.11.2011-25.11.2011 CZ 2014 JD 1 PR RVO:67985556 http://hdl.handle.net/11104/0221735 S 2011 pdf http://library.utia.cas.cz/separaty/2013/ZOI/novozamsky-source camera identification based on prnu invariant to zoom.pdf cav_un_epca*0391294 Doktorandské dny 2011 sborník workshopu doktorandů FJFI oboru Matematické inženýrství 978-80-01-04907-5 163 173 Praha ČVUT Praha 2011 Ambrož P. 340 Masáková Z. 340
