The authors propose a framework to encrypt Baseline JPEG files directly at bitstream level, i.e., without the need to recompress them. The authors\u2019 approach enables encrypting more than 25 pictures per second in VGA resolution, allowing real-time operation in typical video surveillance applications. In addition, their approach preserves the length of the bitstream while being completely format-compliant. Furthermore, the authors show that an attack on the encryption process, which partly relies on AES, is practically infeasible.<\/p>","DOI":"10.4018\/jdcf.2013070101","type":"journal-article","created":{"date-parts":[[2013,9,9]],"date-time":"2013-09-09T12:59:46Z","timestamp":1378731586000},"page":"1-14","source":"Crossref","is-referenced-by-count":30,"title":["Bitstream-Based JPEG Encryption in Real-time"],"prefix":"10.4018","volume":"5","author":[{"given":"Stefan","family":"Auer","sequence":"first","affiliation":[{"name":"Salzburg University of Applied Sciences, Salzburg, Austria"}]},{"given":"Alexander","family":"Bliem","sequence":"additional","affiliation":[{"name":"Salzburg University of Applied Sciences, Salzburg, Austria"}]},{"given":"Dominik","family":"Engel","sequence":"additional","affiliation":[{"name":"Salzburg University of Applied Sciences, Salzburg, Austria"}]},{"given":"Andreas","family":"Uhl","sequence":"additional","affiliation":[{"name":"Department of Computer Sciences, University of Salzburg, Salzburg, Austria"}]},{"given":"Andreas","family":"Unterweger","sequence":"additional","affiliation":[{"name":"Department of Computer Sciences, University of Salzburg, Salzburg, Austria"}]}],"member":"2432","reference":[{"key":"jdcf.2013070101-0","unstructured":"Barrett, S.
