Patent number: 9153006Abstract: Methods and devices are provided to thwart analysis of a watermarking system by preventing analysis of watermarks in a host content. Upon receiving a content at a watermark embedding device, the content is analyzed to ascertain whether one or more test features are present in at least a first portion of the received content. When the analysis reveals that one or more test features are present, embedding of watermarks in at least the first portion of the received content is disabled. The test features of interest include a temporal, a spatial and/or a frequency characteristic such that, if a region of the content that includes test feature is embedded with a watermark, at least one characteristic of the embedded watermark is detectable upon analysis of that region. The test feature can, for example, approximate an impulse signal, a step function signal or a pure sinusoidal signal.Type: GrantFiled: August 15, 2014Date of Patent: October 6, 2015Assignee: Verance CorporationInventors: Rade Petrovic, Babak Tehranchi, Joseph M.

Patent number: 8538066Abstract: Methods and devices are provided to embed imperceptible watermarks into a host content and to subsequently extract embedded watermarks in a manner so as to achieve desired levels of robustness, transparency and security. For a particular host content, a first number of embedding opportunities are used to insert watermarks, which is less than a number of all embedding opportunities within the host content. Watermarks are extracted from a first number of watermark extraction opportunities, which is less than a number of all watermark extraction opportunities associated with the host content. The relationship between the first number of embedding opportunities, the first number of watermark extraction opportunities and the number of all watermark extraction opportunities is such that a circumvention attempt that overwrites watermarks at all extraction opportunities degrades perceptual quality of the host content below a desired perceptual quality level.Type: GrantFiled: September 4, 2012Date of Patent: September 17, 2013Assignee: Verance CorporationInventors: Rade Petrovic, Babak Tehranchi, Joseph M.

Patent number: 8340348Abstract: Methods and apparatus for thwarting circumvention of watermark detection are provided. When content is received at a device that is equipped with a watermark extractor, an attacker may disguise the form of the received content in an attempt to circumvent detection of watermarks that are embedded in the content. A signal processing operation is performed on the received content such that the signal processing operation does not significantly degrade the perceptual quality of the content if the content is indeed in the form that is purported to be. The signal processing operation, however, significantly degrades the perceptual quality of the content if the content is in a different form, thereby discouraging the attacker's attempts to thwart watermark detection.Type: GrantFiled: September 28, 2011Date of Patent: December 25, 2012Assignee: Verance CorporationInventors: Rade Petrovic, Babak Tehranchi, Joseph M.

Methods and apparatus for enhancing the robustness of watermark extraction from digital host content
Patent number: 8005258Abstract: Methods and apparatus for enhancing the robustness of watermark extraction from digital host content are provided. Embedded watermarks may be extracted from received digital host content in accordance with a stego key. A first watermark is extracted and a number of errors in the first extracted watermark is assessed. If the number of errors is above a first pre-determined value, at least a second watermark is extracted from the host content. A number of errors in at least the second extracted watermark is assessed. If the number of errors in at least the second extracted watermark is above a second pre-determined value, the extraction results for the extracted watermarks are combined in order to cumulatively assess the validity of the first extracted watermark and at least the second extracted watermark.Type: GrantFiled: September 25, 2009Date of Patent: August 23, 2011Inventors: Rade Petrovic, Babak Tehranchi, Joseph M.

Publication number: 20060239501Abstract: Methods and apparatus for embedding digital watermarks into a digital host content are provided. A digital host content is received, e.g., at a receiver or other device incorporating a receiver. One or more watermark embedding technologies is selected. Multiple embedding opportunities are identified within the host content. A subset of the identified embedding opportunities is selected. A multiplicity of digital watermarks are then embedded into the host content in accordance with the selected subset of embedding opportunities utilizing the one or more selected watermark embedding technologies. The selecting of the subset of embedding opportunities may be adapted to provide a desired tradeoff between levels of robustness, security, and transparency of the watermark. A plurality of watermarking embedding technologies may be selected and used in the embedding step.Type: ApplicationFiled: April 26, 2005Publication date: October 26, 2006Applicant: Verance CorporationInventors: Rade Petrovic, Babak Tehranchi, Joseph Winograd, Kanaan Jemili

Patent number: 7046808Abstract: A system for determining the amount of processing that has been applied to watermarked signal. A steganographic signal is provided that includes an original signal and an embedded fragile watermark. The fragile watermark is characterized by a low energy and a high redundancy in comparison to a robust watermark. The steganographic signal is communicated over a distribution channel to a decoder. At the decoder, a measure of a presence of the fragile watermark in the acquired steganographic signal is provided, along with an estimate of the fragility profile of the fragile watermark for this particular original signal. Based on these factors, a estimate is made of the amount of processing that the steganographic signal has undergone. This processing can include, for example, A/D and D/A conversions, resampling, band-limiting, perceptual compression/decompression, etc.Type: GrantFiled: March 24, 2000Date of Patent: May 16, 2006Assignee: Verance CorporationInventors: Eric Metois, Rade Petrovic, Kanaan Jemili
