- 1DEDA toolkit decodes hidden printer tracking dotsโDEDA โ Tracking Dots Extraction, Decoding and Anonymisation Toolkit
DEDA, an open-source toolkit for extracting, decoding and anonymising the yellow tracking dots that many colour laser printers secretly print on every page, has drawn attention online. The dots can identify the machine and serial number used to print a document, raising privacy concerns. The tool lets users read and remove this forensic metadata, and researchers and privacy advocates are discussing its implications for anonymity.
- 2Two Laser Pulses Unlock Previously Unreachable Electron StatesโTwo Laser Pulses Unlock Electron States Physicists Had Never Reached Before
Physicists report that firing two precisely timed laser pulses at a material has pushed electrons into quantum states that were previously out of reach, opening a new way to probe and control matter. The technique could inform future research in ultrafast physics and materials science, though practical applications remain distant.
- 3Laser Offers Precise Control of Phonons at NanoscaleโLaser Provides Precise Control over Phonons at Nanoscale Level
Researchers report a laser technique that allows precise control over phonons โ quantized vibrations โ at the nanoscale. The advance could matter for developing phonon-based computing, thermal management in chips, and ultra-sensitive sensors, as it gives scientists a way to direct heat-carrying vibrations with far greater accuracy than before.
- 4DEDA Toolkit Decodes Printer Tracking Dots for AnonymityโDEDA - Tracking Dots Extraction, Decoding and Anonymisation Toolkit https://github.com/dfd-tud/deda # HackerNews # Tech
DEDA, an open-source toolkit for extracting, decoding and anonymising yellow tracking dots that colour laser printers secretly print on documents, has been released on GitHub by researchers at TU Dresden. The tool lets anyone read the hidden identifying information embedded in printed pages and remove it, raising fresh concerns about printer surveillance and document privacy.
