20090123020 | Method and Device for Reading Digital Tatooing, Computer Software Package and Corresponding Storage Means - The invention relates to a method of reading a watermark, of the type comprising a step of determining at least one watermarking message contained in a data set, possibly preceded by a step of determining at least one suite of parameters of a watermarking channel undergone by the data set, each suite of channel parameters comprising at least one channel parameter. The step of determining at least one watermarking message and/or the prior step of determining at least one suite of channel parameters comprises (comprise): an estimation phase, consisting in processing at least one batch of data comprising data of the data set, so as to obtain N estimated element(s), with N≧0; and a verification phase, consisting in validating or invalidating, in view of the entirety or of at least a subset of the data set, each estimated element. In the foregoing, each estimated element is an estimated watermarking message, in the case of the step of determining at least one watermarking message, and a suite of estimated-channel parameters, in the case of the prior step of determining at least one suite of channel parameters. | 05-14-2009 |

20090208131 | Method and Device for Watermarking on Stream - The invention relates in particular to a stream-wise method of watermarking independent of the compression parameters used (for example type of the transform) so as to allow the reading of the watermarking inserted independently of the format of the data received. The watermarking method according to the invention consists in generating a contribution matrix in the transformation space, in projecting it into another domain and in watermarking the data in this domain on the basis of the projected matrix so as to allow a watermark reader operating in the transformed transformation space to read back the inserted watermarking in the transformation space. The contribution matrix representing the modifications induced on the coefficients in the transformation space by insertion of the watermarking cue in this same domain. | 08-20-2009 |
20090217052 | Method for time-stamped watermarking, method and device for time stamp decoding use - The invention relates to a method for watermarking at least one timestamp in a set of support data, comprising the following steps for each timestamp: association with the timestamp of the value at a given time of a reference timestamp signal, that is a determinist signal varying over time in a given temporal reference and being written as s(t), wherein t is incremented according to an incrementing step equal to one predetermined time unit; and watermarking of the value in the set of support data. The invention also relates to a corresponding decoding method comprising the following steps: reading, in the set of support data, of at least one value of a phase-shifted timestamp signal, of the same form as the reference timestamp signal but having in relation to this signal an unknown phase shift φ in a given temporal reference, the previous watermarking of each timestamp consisting in a watermarking of the value at a given watermarking time of the reference timestamp signal; estimation of the phase shift φ from the at least one read value of the phase-shifted timestamp signal and from the knowledge of the reference timestamp signal; and for the at least one read value, read at a given time t | 08-27-2009 |

20130064368 | METHODS AND DEVICES FOR SELECTIVE FORMAT-PRESERVING DATA ENCRYPTION - Selective data encryption of a file, in particular an H.264/MPEG-4 AVC data stream. If a first unit in the data stream is to be encrypted, it is encrypted and the encryption is put into a further unit, preferably in the data stream. A substitution unit is generated and put in the place of the first unit; if necessary, at least one header value is taken from the first unit for use in the substitution unit. A decryptor receives the encrypted data stream, extracts and decrypts the further unit and replaces the substitution unit with a regenerated first unit. | 03-14-2013 |
