摘要： 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 and back to digital form. Signature points are selected from 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. Identification of a subject image includes ensuring that the subject image is normalized with respect to the original image or the signed image. Preferably, the normalized subject image is compared with the stored digital signature.

摘要： 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.
摘要翻译：数字图像被微妙地改变以允许其随后的识别，而基本上不改变其人的外观。这些变化仅影响少数图像像素。通过检查可疑图像中是否存在这种更改，可疑图像可以与原始图像匹配。

摘要： 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.

摘要： 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.
