TL;DR: In this article, a patient's disease is diagnosed and/or treated using electronic data communications between not only the physician and his/her patient, but also via the use of electronic data communication between the physicians and one or more entities which can contribute to the patient's diagnosis and treatment, including information that was priorly received electronically from the patient and was developed as a consequence of an electronic messaging interaction that occurred between the patient, and the physician.
Abstract: Patient disease is diagnosed and/or treated using electronic data communications between not only the physician and his/her patient, but via the use of electronic data communications between the physician and one or more entities which can contribute to the patient's diagnosis and/or treatment, such electronic data communications including information that was priorly received electronically from the patient and/or was developed as a consequence of an electronic messaging interaction that occurred between the patient and the physician. Such other entities illustratively include a medical diagnostic center and an epidemiological database computer facility which collects epidemiological transaction records from physicians, hospitals and other institutions which have medical facilities, such as schools and large businesses. The epidemiological transaction record illustratively includes various medical, personal and epidemiological data relevant to the patient and his/her present symptoms, including test results, as well as the diagnosis, if one has already been arrived at by the e-doc. The epidemiological database computer facility can correlate this information with the other epidemiological transaction records that it receives over time in order to help physicians make and/or confirm diagnoses as well as to identify and track epidemiological events and/or trends.

TL;DR: This article illustrates the idea of instance-based browsing, which involves structuring retrieval around the critiquing of previously retrieved examples, and retrieval strategies, or knowledge-based heuristics for finding relevant information, with examples of working FindMe systems.
Abstract: While the explosion of online information has introduced new opportunities for finding and using electronic data, it has also underscored the problem of isolating useful information and making sense of large, multidimensional information spaces. In response to this problem, we have developed an approach to building data tour guides, called FindMe systems. These programs know enough about an information space to help users navigate through it, making sure they not only come away with useful information but also insights into the structure of the information space itself. In these systems, we have combined the idea of instance-based browsing, which involves structuring retrieval around the critiquing of previously retrieved examples, and retrieval strategies, or knowledge-based heuristics for finding relevant information. This article illustrates these techniques with examples of working FindMe systems, and describes the similarities and differences between them. FindMe tour guides help users to select the perfect car, movie, restaurant, stereo or apartment on the World Wide Web.

Journal ArticleDOI
TL;DR: This article examines the conflicts between establishing health care databases and protecting a person's right to privacy, explores ethical values that may help to resolve those conflict, reviews applicable federal and state laws to determine whether they facilitate efficient collection of health care data while adequately protecting personal privacy, and proposes national legislation to safeguard the privacy of personal information on health care.
Abstract: During the early 1990s, the U.S. government addressed the issue of providing universal health care to all its citizens. Although this issue has not been completely resolved, centralization of electronic data and sharing of health care information among insurers and providers have been pursued. The emergence of electronic data banks in health care has raised another issue: each citizen's right to privacy compared with the collective benefit to society when critical data on quality assurance and scientific research are shared by an array of network users. The choices we face are difficult, and the solution may necessarily reflect a compromise that alters traditional beliefs in the right to personal privacy. However, Congress can take the initiative by enacting statutes to ensure that sensitive information contained in electronic patient records is not divulged without a patient's consent and is protected against fraudulent access and abuse.

TL;DR: In this article, a method and apparatus for transmitting electronic messages wherein payment is required for the transmission is presented, where the electronic message preferably is encrypted prior to transmission and decrpyted when it is received by an electronic addressee.
Abstract: A method and apparatus for transmitting electronic messages wherein payment is required for the transmission. Payment is made as messages are transmitted using previously obtained electronic stamps or credits. An electronic sender obtains in advance the electronic stamps which are usable to pay for the transmission. Electronic stamps are represented by a signal which is transmitted with the message and must be present for transmission to occur. The encoded signal preferably includes authenticating data. The balance of electronic stamps available is debited as stamps are used and incremented as they are obtained. The value of stamps necessary to pay for a transmission can vary according to the data content of the electronic message and the invention therefore preferably examines the data content of the message and encodes the proper electronic stamp amount. The invention also preferably alters the encoded signal representing the stamps which have been used for transmission to prevent further use of the signal as payment for another transmission. The electronic message preferably is encrypted prior to transmission and decrpyted when it is received by an electronic addressee.

TL;DR: In this article, a nonvolatile memory is provided with a counterfeit detection mechanism by storing an encryption key and performing cryptographic operations on chip, which is based on unique data within the non-volatile memories.
Abstract: A nonvolatile memory is provided with a counterfeit detection mechanism by storing an encryption key and performing cryptographic operations on chip. The encryption key, which is stored in the nonvolatile memory in a protected manner such that it is never exported, is based on unique data within the nonvolatile memory. Unless an expected encryption key calculated from the unique data matches the stored encryption key, the system will not allow the resource containing the nonvolatile memory to be utilized. Equivalence of the expected and stored encryption keys is tested by enciphering and deciphering a random number. The data in the nonvolatile memory may be copied but not altered since each data block includes an electronic signature. Modification of the data in the nonvolatile memory as part of an effort to counterfeit the stored encryption key is therefore useless.
