In our project we focused on hidden communications in VoIP and GSM in which voice data is typically compressed and transmitted in realtime. A framework has been developed to meet these requirements, providing interfaces for robust steganographic algorithms.\n","original_language":"eng","persons":["Marcus Nutzinger","Rainer Poisel"],"tags":["27c3"," Hacking"],"view_count":38,"promoted":false,"date":"2010-12-28T01:00:00.000+01:00","release_date":"2011-01-04T01:00:00.000+01:00","updated_at":"2024-08-16T21:45:02.806+02:00","length":3460,"duration":3460,"thumb_url":"https://static.media.ccc.de/media/congress/2010/27c3-4138-en-secure_communications_below_the_hearing_threshold.jpg","poster_url":"https://static.media.ccc.de/media/congress/2010/27c3-4138-en-secure_communications_below_the_hearing_threshold_preview.jpg","timeline_url":"https://static.media.ccc.de/media/congress/2010/import-be08ac24c3b79ec5d1-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/congress/2010/import-be08ac24c3b79ec5d1-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/27c3-4138-en-secure_communications_below_the_hearing_threshold","url":"https://api.media.ccc.de/public/events/import-be08ac24c3b79ec5d1","conference_title":"27C3: We Come In Peace","conference_url":"https://api.media.ccc.de/public/conferences/27c3","related":[{"event_id":30,"event_guid":"import-26f964c4d0bd0d0add","weight":1},{"event_id":1179,"event_guid":"import-b30e3e74eed3d62975","weight":1},{"event_id":1456,"event_guid":"import-ffedc66f28f81c9a2e","weight":1},{"event_id":1468,"event_guid":"import-c101d62bc033267900","weight":1},{"event_id":1488,"event_guid":"import-df9d8732b1d4fe59a0","weight":1},{"event_id":2414,"event_guid":"b27fffbe-258a-4bc9-a27c-f7558bcba446","weight":1},{"event_id":3041,"event_guid":"29aaed8b-5b17-4feb-a9fc-7cc584682746","weight":1},{"event_id":3640,"event_guid":"700a07e7-a9c4-437b-a4c5-4491b23a9b4a","weight":1},{"event_id":3747,"event_guid":"fc6c53de-ec9d-4966-a912-5cfaf54c0dd2","weight":1},{"event_id":4756,"event_guid":"ff07fa0e-c32a-11e7-b8e4-fb6414355a49","weight":1},{"event_id":4783,"event_guid":"79c1ee55-8004-4dcd-9282-9f7acae9c94a","weight":1},{"event_id":4823,"event_guid":"bf924a39-2860-4e27-8741-b8fa0c010363","weight":1},{"event_id":4826,"event_guid":"16645200-2036-4a3c-a44d-a5ff44ac2991","weight":1}],"recordings":[{"size":680,"length":3460,"mime_type":"audio/ogg","language":"eng","filename":"27c3-4138-en-secure_communications_below_the_hearing_threshold.ogg","state":"downloaded","folder":"ogg-audio-only","high_quality":true,"width":720,"height":576,"updated_at":"2014-05-10T15:26:52.863+02:00","recording_url":"https://cdn.media.ccc.de/congress/2010/ogg-audio-only/27c3-4138-en-secure_communications_below_the_hearing_threshold.ogg","url":"https://api.media.ccc.de/public/recordings/2826","event_url":"https://api.media.ccc.de/public/events/import-be08ac24c3b79ec5d1","conference_url":"https://api.media.ccc.de/public/conferences/27c3"},{"size":680,"length":3460,"mime_type":"video/mp4","language":"eng","filename":"27c3-4138-en-secure_communications_below_the_hearing_threshold.mp4","state":"downloaded","folder":"mp4-h264-HQ","high_quality":true,"width":720,"height":576,"updated_at":"2016-01-27T11:03:43.892+01:00","recording_url":"https://cdn.media.ccc.de/congress/2010/mp4-h264-HQ/27c3-4138-en-secure_communications_below_the_hearing_threshold.mp4","url":"https://api.media.ccc.de/public/recordings/2825","event_url":"https://api.media.ccc.de/public/events/import-be08ac24c3b79ec5d1","conference_url":"https://api.media.ccc.de/public/conferences/27c3"},{"size":680,"length":3460,"mime_type":"video/webm","language":"eng","filename":"27c3-4138-en-secure_communications_below_the_hearing_threshold.webm","state":"downloaded","folder":"webm","high_quality":true,"width":720,"height":576,"updated_at":"2016-01-27T11:03:43.921+01:00","recording_url":"https://cdn.media.ccc.de/congress/2010/webm/27c3-4138-en-secure_communications_below_the_hearing_threshold.webm","url":"https://api.media.ccc.de/public/recordings/2824","event_url":"https://api.media.ccc.de/public/events/import-be08ac24c3b79ec5d1","conference_url":"https://api.media.ccc.de/public/conferences/27c3"}]}
