Audio Watermarking, I.e., Embedding Inaudible Data In The Audio Signal (epo) Patents (Class 704/E19.009)
  • Patent number: 11915710
    Abstract: A conference terminal and an embedding method of audio watermarks are provided. In the method, a first speech signal and a first audio watermark signal are received respectively. The first speech signal relates to a speaker corresponding to another conference terminal, and the first audio watermark signal corresponds to the another conference terminal. The first speech signal is assigned to a host path to output a second speech signal. The first audio watermark signal is assigned to an offload path to output a second audio watermark signal. The host path provides more digital signal processing (DSP) effects than the offload path. The second speech signal and the second audio watermark signal are synthesized to output a synthesized audio signal. The synthesized audio signal is adapted for audio playback. A completed audio watermark signal is outputted accordingly.

  • Patent number: 11837243
    Abstract: A processing method of a sound watermark and a speech communication system are provided. Multiple sinewave signals are generated. Frequencies of the sinewave signals are different from each other, and the sinewave signals belong to a high-frequency sound signal. A watermark pattern is mapped into a time-frequency diagram, to form a watermark sound signal. Two dimensions of the watermark pattern in a two-dimensional coordinate system respectively correspond to a time axis and a frequency axis in the time-frequency diagram. Each of multiple audio frames on the time axis corresponds to the sinewave signals with different frequencies on the frequency axis. A speech signal and the watermark sound signal are synthesized in a time domain to generate a watermark-embedded signal. Accordingly, a sound watermark may be embedded in real-time.

  • Patent number: 11468435
    Abstract: In a blockchain network, a “cold wallet” allows users to securely create and store their private key and sign their transaction data only when the wallet is completely offline. When a user requests a transaction, a user key tag that identifies the user's key is determined. The transaction data and the user's key tag are transmitted to a cold wallet that includes an HSM Trusted Client and an HSM over a first one-way communication channel during a window in a first sequence of connection windows. Inside the cold wallet, the HSM Trusted Client uses the user key tag to determine an encrypted version of the user's signing key. During a processing window, the transaction data and encrypted signing key are transmitted to the HSM, where a cleartext key is recovered and used to sign the transaction, and the signed transaction is transmitted back to the HSM Trusted Client. During a second connection window, the signed transaction is transmitted from the HSM Trusted Client for transmission to the blockchain network.

    Abstract: Methods, devices, and computer program products enable the embedding of forensic marks in a host content that is in compressed domain. These and other features are achieved by preprocessing of a host content to provide a plurality of host content versions with different embedded watermarks that are subsequently compressed. A host content may then be efficiently marked with forensic marks in response to a request for such content. The marking process is conducted in compressed domain, thus reducing the computational burden of decompressing and re-compressing the content, and avoiding further perceptual degradation of the host content. In addition, methods, devices and computer program products are disclosed that obstruct differential analysis of such forensically marked content.

  • Publication number: 20090157391
    Abstract: An audio fingerprint is extracted from an audio sample, where the fingerprint contains information that is characteristic of the content in the sample. The fingerprint may be generated by computing an energy spectrum for the audio sample, resampling the energy spectrum logarithmically in the time dimension, transforming the resampled energy spectrum to produce a series of feature vectors, and computing the fingerprint using differential coding of the feature vectors. The generated fingerprint can be compared to a set of reference fingerprints in a database to identify the original audio content.

    Abstract: A system and method are provided for automatically routing a diagnostic interpretation from diagnostic data received from a diagnostic source. The diagnostic interpretation is produced automatically using a voice recognition system. Along with the transcription of the interpretation, the voice recognition system returns a level of confidence of the voice recognition. Based on this level of confidence, the system automatically routes the transcribed interpretation to the appropriate destination for further processing.

  • Publication number: 20080215333
    Abstract: A method of embedding data into an audio signal provides a data sequence for embedding in the audio signal and computes masking thresholds for the audio signal from a frequency domain transform of the audio signal. The masking thresholds correspond to subbands of the audio signal, which are obtained from a masking model used to compress the audio signal. The method applies the masking threshold to the data sequence to produce masked data sequence and inserts the masked data sequence in the audio signal to produce an embedded audio signal. A method of detecting data embedded in an audio signal analyzes the audio signal to estimate the masking threshold used in embedding the data and applies the estimated masking threshold to the audio signal to extract the embedded data.

  • Publication number: 20080208573
    Abstract: The present invention relates to methods and apparatuses for speech signal encoding and decoding. In accordance with the invention, a discrete time speech signal is encoded by identifying a speech element in the speech signal. If the speech element is identified for the first time, the encoder (108) creates a unique tag representing the speech element and an associating between the speech element and the unique tag in a memory and transmits the speech element in discrete time form and the tag and an indication that the tag is to represent the speech element to a decoder (118). If the speech element was identified before, the encoder (108) obtains a unique tag representing the speech element from the memory, removes the speech element from the speech signal and transmits the unique tag representing the speech element as obtained from the memory.

    Abstract: A method of implementing an equalizer in an audio signal decoder and an apparatus therefor are provided. According to the method and apparatus, a signal output from an audio signal decoder is not processed by an equalizer, but the values of frequency components are adjusted according to a user's input before subband sample data is transformed into a frequency domain signal in an audio signal decoder, thereby implementing an equalizer in a codec. In this way, the complexity of implementing an apparatus for reproducing an audio signal can be reduced and delay of an equalizer can be reduced.

  • Publication number: 20080097761
    Abstract: Watermarking of a motion picture release print occurs by providing on at least one soundtrack at least one tone of a particular frequency on at least one location unique to the release print. Typically, placement of the particular frequency tone occurs on location(s) where the tone will have minimal impact on the existing soundtrack audio. A record of location(s) at which the particular frequency tone appears on the release print is maintained to facilitate comparison with the tones detected in audio visual work to determine whether the audio of an illegal media was recorded from that release print.
