Patent number: 7831832Abstract: Described herein is an implementation that produces a new representation of a digital good (such as an image) in a new defined representation domain. In particular, the representations in this new domain are based upon matrix invariances. In some implementations, the matrix invariances may, for example, heavily use singular value decomposition (SVD).Type: GrantFiled: January 6, 2004Date of Patent: November 9, 2010Assignee: Microsoft CorporationInventors: S. Serdar Kozat, M. Kivanc Mihcak, Ramarathnam Venkatesan

Patent number: 7634660Abstract: An implementation of a technology is described herein for deriving robust non-local characteristics and quantizing such characteristics for blind watermarking of a digital good. This technology finds the proper balance between minimizing the probability of false alarms (i.e., detecting a non-existent watermark) and the probability of misses (i.e., failing to detect an existing watermark). The technology, described herein, performs quantization index modulation (QIM) based upon non-local characteristics of the digital good. Non-local characteristics may include statistics (e.g., averages, median) of a group of individual parts (e.g., pixels) of a digital good. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.Type: GrantFiled: December 15, 2004Date of Patent: December 15, 2009Assignee: Microsoft CorporationInventors: M.

Patent number: 7620199Abstract: Systems and methods are described that apply a watermark to data, such as data representing an image. In one implementation, the complexity of the image is measured. A quantization step size is calculated, based in part on the measured complexity of the image. A watermark or message is embedded into the image using the quantization step sizes derived for each coefficient of interest. In a further implementation, a mark decoding system is configured to extract the embedded message from the image data.Type: GrantFiled: August 4, 2005Date of Patent: November 17, 2009Assignee: Microsoft CorporationInventors: M. Kivanc Mihcak, Yuqun Chen, Mariusz Jakubowski

Publication number: 20090067748Abstract: Exemplary methods for estimating an orientation angle and a translation values for scanned images are disclosed. The methods described herein may be embodied as logic instructions on a computer-readable medium. In one exemplary implementation meaningful image information is removed from a scanned image, resulting in a transformed image that comprises alternating, parallel lines disposed at an orientation angle relative to an orthogonal axis. The orientation angle may be determined using geometric techniques or statistical correlation techniques, and statistical correlation techniques may be implemented to determine translation values.Type: ApplicationFiled: November 17, 2008Publication date: March 12, 2009Applicant: Microsoft CorporationInventors: Mustafa Kesal, M.

Patent number: 7406195Abstract: An implementation of a technology is described herein for recognizing the perceptual similarity of the content of digital goods. At least one implementation, described herein, introduces a new hashing technique. More particularly, this hashing technique produces hash values for digital goods that are proximally near each other, when the digital goods contain perceptually similar content. In other words, if the content of digital goods are perceptually similar, then their hash values are, likewise, similar. The hash values are proximally near each other. This is unlike conventional hashing techniques where the hash values of goods with perceptually similar content are far apart with high probability in some distance sense (e.g., Hamming). This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.Type: GrantFiled: August 15, 2005Date of Patent: July 29, 2008Assignee: Microsoft CorporationInventors: M.

Patent number: 7391884Abstract: Exemplary methods for performing a statistical analysis of scanned images are disclosed. The methods described herein may be embodied as logic instructions on a computer-readable medium. In one exemplary implementation a correlation value is determined between a scanned image included in a digital file and an original digital image, and a signal is generated indicating whether the correlation value exceeds a threshold.Type: GrantFiled: November 14, 2003Date of Patent: June 24, 2008Assignee: Microsoft CorporationInventors: Mustafa Kesal, M.

Patent number: 7356161Abstract: Methods and systems for quantization and data embedding are described. In at least some embodiments, a transform is applied on an image that is to be watermarked and statistics associated with the image are computed. The computed statistics are quantized using a symmetric lattice, and a watermark is computed using the lattice quantized statistics. The watermark is then inserted into the image.Type: GrantFiled: June 1, 2004Date of Patent: April 8, 2008Assignee: Microsoft CorporationInventors: Kamal Jain, Ramarathnam Venkatesan, M. Kivanc Mihcak

Patent number: 7302079Abstract: An implementation is described herein facilitates certification of goods and/or identifications of the source of such goods. At least one implementation, described herein, embeds a watermark into a relatively small amount of data in a deterministic manner. At least one implementation, described herein, generates an authentication transformation matrix based, at least in part, upon an authentication watermark and a pre-defined humanly perceptible authentication pattern (e.g., image, audio). With this implementation, it obtains subject goods that may have the authentication watermark embedded therein. It generates a humanly perceptible resultant pattern (e.g., image, audio) based, at least in part, upon the watermark detected in subject goods and the transformation matrix. If the detected watermark is the authentication watermark, then the resultant pattern and the pre-defined authentication pattern will match (or nearly so).Type: GrantFiled: November 19, 2003Date of Patent: November 27, 2007Assignee: Microsoft CorporationInventors: Mustafa Kesal, M.
