==METHOD AND DEVICE FOR PROVIDING A SIGNED AUDIO BITSTREAM WITH VARIABLE GRANULARITY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240323029 titled 'METHOD AND DEVICE FOR PROVIDING A SIGNED AUDIO BITSTREAM WITH VARIABLE GRANULARITY

The abstract describes a method for providing a signed bitstream in the process of capturing and encoding an audio signal as a bitstream, where data units represent time segments of the audio signal. The method involves assigning scores to data units, monitoring accumulated scores back to a reference point, inserting a signature unit with a digital signature into the bitstream when a threshold is reached, and resetting the reference point. The score is based on the content of the time segment, contextual information, and conditions of capturing the segment.

* Assigning scores to data units
* Monitoring accumulated scores back to a reference point
* Inserting a signature unit with a digital signature into the bitstream
* Resetting the reference point
* Score based on content, contextual information, and capturing conditions

2. What are the potential implications of this technology in the music industry?
- This technology can help prevent unauthorized tampering with audio files, ensuring the integrity of music recordings.


==Original Abstract Submitted==

a method of providing a signed bitstream, performed in association with a process of capturing an audio signal and encoding it as a bitstream, which includes a sequence of data units representing time segments of the audio signal. the method comprises: assigning a score to each data unit; monitoring an accumulated score of data units back to a reference point; when the accumulated score reaches a threshold, inserting into the bitstream a signature unit including a digital signature of fingerprints of a subsequence of the data units back to the reference point; and resetting the reference point. the score is based on a) a detected content of the time segment of the audio signal corresponding to the data unit, b) contextual information relating the time segment to a history of the audio signal, and/or c) information relating to the conditions of capturing the time segment.
