Combining hashing and enciphering algorithms for epidemiological analysis of gathered data.
Summary Objectives: Compiling individual records coming from different sources is necessary for multi-center studies. Legal aspects can be satisfied by implementing anonymization procedures. When using these procedures with a different key for each study it becomes almost impossible to link records from separate data collections. Methods: The originality of the method relies on the way the combination of hashing and enciphering techniques is performed: like in asymmetric encryption, two keys are used but the private key depends on the patient’s identity. Results: The combination of hashing and enciphering techniques provides a great improvement in the overall security of the proposed scheme…
Chaînage de bases de données anonymisées pour les études épidémiologiques multicentriques nationales et internationales : proposition d'un algorithme cryptographique
Background: Compiling individual records coming from different sources is very important for multicenter epidemiological studies; however, European directives and other national legislation concerning nominal data processing must be respected. These legal aspects can be satisfied by implementing mechanisms that allow anonymization of patient data (such as hashing techniques). Moreover, for security reasons, official recommendations suggest using different cryptographic keys in combination with a cryptographic hash function for each study. Unfortunately, this type of anonymization procedure is in contradiction with common requirements in public health and biomedical research because it becom…
Watermarking - A new way to bring evidence in case of telemedicine litigation
International audience; When dealing with medical data sharing, in particular within telemedicine applications, there is a need to ensure information security. Being able to verify that the information belongs to the right patient and is from the right source or that it has been rerouted or modified is a major concern. Watermarking, which is the embedding of security elements, such as a digital signature, within a document, can help to ensure that a digital document is reliable. However, at the same time, questions arise about the validity of watermarking-based proof. In this paper, beyond the technical aspects, we discuss the legal acceptability of watermarking in the context of telemedici…
L'administration conjointe du dossier patient: une responsabilité partagée entre le patient et le praticien
National audience; The main problem faced by patients, health practitioners and the authorities, is namely the gathering and updating of administrative and medical data in order to accurately reconstitute a patient's medical history. Although solutions to accelerate and to ease this gathering are being implemented at the national level in several European countries, as unique health identifier in France, information still have to be validated before use. Through this article, we propose a mixed management of patients' data, split between the patient regarding administrative information and the Medical Practitioner (MP) regarding medical information. This method is based on two processes. Th…
