Abstract: The present invention relates to hiding codes in input data, e.g., such as still imagery and motion pictures. One claim recites: embedding an N-bit code with a source signal, N being at least one. The embedding proceeds, for each bit of the N-bit code, according to the following: mapping the bit to a portion of the source signal; changing values of at least two data values associated with the portion in accordance with the bit. The act of changing embeds the N-bit code in a manner that is generally imperceptible to a human observer of the source signal. A related claim recites that the portion includes a data value, and the above method further includes changing the value of the data value in accordance with said bit of the code, an amount of the changing being adjusted based on the value. Of course, other claims and combinations are provided as well.

Abstract: The illustrative embodiment of the present invention enables the delivery of digital media source material from a content provider to a consumer in a manner designed to protect the finished composition and digital media distribution quality source material from being distributed to unauthorized users. A digital media content provider delivers source material that is less than distribution quality (“edit quality”) to a distributor. The distributor forwards the edit quality material to an outside editor for editing. The editor performs the editing process and returns the edited material to the distributor in the form of a composition list. The distributor combines the composition list with additional distribution quality digital media source material to produce a finished composition. By applying just-in-time inventory concepts to the process, the finished composition is produced only as needed and is sent to the consumer upon completion.

Abstract: A method and system for embedding signatures within visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, the signature persisting through image transforms that include resizing as well as conversion to print or film among the pixels of an original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount detectable by a digital scanner. The adjusted signature points form a digital signature which is stored for future identification of subject images derived from the image. In one embodiment, a signature is embedded within an image by locating relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema. Preferably, the signature is redundantly embedded in the image such that any of the redundant representations can be used to identify the signature.

Abstract: A method and system for embedding signatures within visual images in both digital representation and print or film.

Abstract: A digital image is scanned to generate image data, which is processed to steganographically embed plural-bit auxiliary data. The system is useful, e.g., for capturing and marking digital images without noticeably changing their visual appearance.

Abstract: A portable data collection device is provided for diagnostic image and data collection at a remote location. The device is implemented as an otoscope including a speculum and light source for illumination of the ear canal. A digital camera element collects the reflected images and provides the images to a processor. The processor processes the images using pattern matching techniques and displays and/or stores suitable images. The images are transferred to a base station for subsequent transmission to a remote server or computer, where an authorized party may access and examine the images. An authorization or prescription from the remote server or computer may be required to enable data collection and transmission by the otoscope.

Abstract: A method of marking a work of authorship without apparent evidence of data alteration. The work (e.g., an image) is represented by a set of data elements (e.g., pixels). The marking includes providing first plural-bit data, and computing therefrom additional, error correcting data. This composite set of data is used in image marking, permitting at least certain errors to be discerned and corrected when the marking is later discerned from the image.

Abstract: A prescription-controlled diagnostic data collection system for collecting, storing and receiving medical diagnostic data. A remote medical diagnostic device is configured to collect and transmit diagnostic data. A health service provider prepares a prescription that authorizes the remote diagnostic device to collect and/or transmit diagnostic data. The prescription includes an identifier unique to the device. A central server receives and stores the prescription from the prescribing party and stores status and data information associated with the prescription. A base unit transfer data and authorization information between the remote medical diagnostic device and the server. The remote diagnostic device is operable by a patient independently of the server and the health care provider to collect the diagnostic data, and is operable to transmit the diagnostic data to the server when appropriate authorizations have been received by the base unit from the server.

Abstract: A digital image is subtly changed to permit its subsequent identification, without essentially altering its human appearance. The changes affect only a minority of the image pixels. By checking for the presence of such changes in a suspect image, a suspect image can be matched with the original image.

Abstract: Plural-bit data is encoded in an image without leaving apparent evidence of image alteration. The image is represented by data elements (e.g., pixels) whose values are changed to effect the encoding. The particular data elements to be changed are selected not on their individual values, but rather on an attribute of a neighboring group of data elements.

Abstract: Plural-bit data is encoded in an image without leaving apparent evidence of image alteration. The image is represented by data elements (e.g., pixels) whose values are changed to effect the encoding. The changes are desirably effected in groups, e.g., pixel groupings 5-10 pixels in height and width, and in a manner calculated to keep the changes relatively inconspicuous.
