Er kan een watermerk worden geplaatst in een afbeelding, audio en video. Dit watermerk maakt het mogelijk om publicaties te traceren en te herkennen omdat er extra informatie in zit zoals licentie-informatie. Digitale watermerken kunnen ook een signaal (bv. bij televisie) identificeren en een automatische actie in gang brengen bij distributie; dit wordt <i>remote triggering</i> genoemd. Deze techniek wordt gebruikt om bijvoorbeeld lokale reclame te laten afspelen. </p> <div class="mw-heading mw-heading3"><h3 id="Vervalsing_en_piraterij_tegengaan">Vervalsing en piraterij tegengaan</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Digitaal_watermerk&veaction=edit&section=6" title="Bewerk dit kopje: Vervalsing en piraterij tegengaan" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Digitaal_watermerk&action=edit&section=6" title="De broncode bewerken van de sectie: Vervalsing en piraterij tegengaan"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Door digitale watermerken te plaatsen kan er een serienummer bij elke copij worden geplaatst met informatie over de aankoop van de muziek, afbeelding of video. Deze serienummers kunnen worden bijgehouden in een database en automatisch gecontroleerd worden door software. Ook kan het digitaal watermerk informatie bevatten of de digitale informatie mag worden gekopieerd. Deze laatste techniek is relatief gemakkelijk te omzeilen door simpelweg bit per bit te kopiëren. </p> <div class="mw-heading mw-heading3"><h3 id="Authenticatie">Authenticatie</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Digitaal_watermerk&veaction=edit&section=7" title="Bewerk dit kopje: Authenticatie" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Digitaal_watermerk&action=edit&section=7" title="De broncode bewerken van de sectie: Authenticatie"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Door een watermerk te plaatsen in documenten kan men de <a href="/wiki/Authenticiteit_(gegevens)" title="Authenticiteit (gegevens)">authenticiteit</a> hiervan controleren. Deze techniek wordt bijvoorbeeld in Amerika gebruikt om valse rijbewijzen tegen te gaan. De foto’s bevatten een digitaal watermerk dat relatief gemakkelijk uitgelezen kan worden met een scanner en zo nagegaan kan worden of het een legitiem rijbewijs is. </p> <div class="mw-heading mw-heading3"><h3 id="Monitoring">Monitoring</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Digitaal_watermerk&veaction=edit&section=8" title="Bewerk dit kopje: Monitoring" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Digitaal_watermerk&action=edit&section=8" title="De broncode bewerken van de sectie: Monitoring"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Digitaal watermerken maken het mogelijk om afbeeldingen, audio en of video’s te traceren op het internet of bij distributie. Het materiaal krijgt dan met behulp van een watermerk extra informatie waarin de datum en tijd van publicatie staan. Grote bedrijven gebruiken dit om te zien of hun dure reclame wel werkelijk op tv of op internet komt te staan op de afgesproken tijdstippen. </p>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Overgenomen van "<a dir="ltr" href="https://nl.wikipedia.org/w/index.php?title=Digitaal_watermerk&oldid=47782374">https://nl.wikipedia.org/w/index.php?title=Digitaal_watermerk&oldid=47782374</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Categorie:Alles" title="Categorie:Alles">Categorieën</a>: <ul><li><a href="/wiki/Categorie:Steganografie" title="Categorie:Steganografie">Steganografie</a></li><li><a href="/wiki/Categorie:Intellectuele-eigendomsrecht" title="Categorie:Intellectuele-eigendomsrecht">Intellectuele-eigendomsrecht</a></li><li><a href="/wiki/Categorie:Informatiebeveiliging" title="Categorie:Informatiebeveiliging">Informatiebeveiliging</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> Deze pagina is voor het laatst bewerkt op 23 okt 2016 om 17:24.</li> <li id="footer-info-copyright">De tekst is beschikbaar onder de licentie <a rel="nofollow" class="external text" href="//creativecommons.org/licenses/by-sa/4.0/deed.nl">Creative Commons Naamsvermelding/Gelijk delen</a>, er kunnen aanvullende voorwaarden van toepassing zijn.
