== Privacy implications == The use of SilverPush to track users across multiple devices has privacy implications and allows for more detailed tracking of users. Data can be collected from multiple devices used by a single user and correlated to form a more accurate picture of the person being tracked.<ref name="ars">{{cite web | url=https://arstechnica.com/tech-policy/2015/11/beware-of-ads-that-use-inaudible-sound-to-link-your-phone-tv-tablet-and-pc/ | title=Beware of ads that use inaudible sound to link your phone, TV, tablet, and PC | date=13 November 2015 | publisher=Ars Technica | accessdate=31 March 2016}}</ref>
In July 2014, TechCrunch reported that SilverPush was using "ultrasonic inaudible sounds" called "audio beacons" along with cookies to reliably track users across multiple devices and that devices with an app containing the SilverPush SDK are constantly listening for audio beacons.<ref>{{cite web | url=https://techcrunch.com/2014/07/24/silverpush-audio-beacons/ | title=SilverPush Says It's Using "Audio Beacons" For An Unusual Approach To Cross-Device Ad Targeting | date=24 July 2014 | publisher=TechCrunch | accessdate=1 April 2016}}</ref>
In April 2015, SilverPush claimed 67 apps were using its code.<ref name="vice">{{cite web | url=https://www.vice.com/en/article/silverpush-ftc-stop-eavesdropping-with-audio-beacons/ | title=Creepy Ad Company Says It Will Stop Eavesdropping With 'Audio Beacons' | date=21 March 2016 | publisher=Vice | access-date=1 April 2016}}</ref>
In October 2015, the Center for Democracy and Technology submitted comments to the Federal Trade Commission (FTC) regarding SilverPush's cross-device tracking technology.<ref name="CDT">{{cite web | url=https://cdt.org/files/2015/10/10.16.15-CDT-Cross-Device-Comments.pdf | title=Re: Comments for November 2015 Workshop on Cross - Device Tracking | publisher=Center for Democracy and Technology | accessdate=1 April 2016}}</ref><ref name="register">{{cite web | url=https://www.theregister.co.uk/2015/11/20/silverpush_soundwave_ad_tracker/ | title=How TV ads silently ping commands to phones: Sneaky SilverPush code reverse-engineered | publisher=The Register | accessdate=1 April 2016}}</ref>
In March 2016, the FTC issued warning letters to 12 app developers using SilverPush code in their apps.<ref name="ftc">{{cite web | url=https://www.ftc.gov/news-events/press-releases/2016/03/ftc-issues-warning-letters-app-developers-using-silverpush-code | title=FTC Issues Warning Letters to App Developers Using 'Silverpush' Code | date=17 March 2016 | accessdate=1 April 2016}}</ref> The FTC warned these developers that they may be violating the FTC Act if they state or imply that their apps are not tracking television viewing habits when they in fact are. Shortly after the FTC warning, SilverPush made an official statement that they are ending the Unique Audio Beacon service.<ref>{{cite web | url=https://www.forbes.com/sites/thomasbrewster/2016/03/21/silverpush-tv-mobile-ad-tracking-killed/ | title=Silverpush Quits Creeping World Out, Ceases Tracking TV Habits Via Inaudible 'Beacons' | work=Forbes | accessdate=1 April 2016}}</ref><ref name="vice" /> However, as of 21 March 2016, SilverPush is still advertising Unique Audio Beacon on their website.<ref name="vice" />
In November 2016, researchers from UCL, UCSB and PoliMI demonstrated the security and privacy implications of the ultrasound cross-device tracking (uXDT) technology used by SilverPush.<ref>{{cite web|author = Vasilios Mavroudis |display-authors=etal |title = Talking behind your Back: Attacks and Countermeasures of Ultrasonic cross-device Tracking|publisher = Black Hat Europe 2016|url=https://www.blackhat.com/eu-16/briefings.html#talking-behind-your-back-attacks-and-countermeasures-of-ultrasonic-cross-device-tracking|accessdate=26 November 2017}}</ref> The most notable of their attacks uses uXDT-enabled applications to deanonymize Tor users.<ref>{{cite web|author = Vasilios Mavroudis |display-authors=etal |title = On the Privacy and Security of the Ultrasound Ecosystem|publisher = Proceedings on Privacy Enhancing Technologies|url=https://reyammer.io/publications/2017_pets_ultrasound.pdf|format = PDF|website=reyammer.io|accessdate=28 April 2026}}</ref>
